Background: The aim of this study was to investigate the effect of dry needling (DN) applied to the abductor hallucis (ABH) muscle on pain function and angle in patients with hallux valgus (HV). Methods: The study included 31 HV patients. Patients were randomly divided into two groups. The first group received toe-spread-out (TSO) exercise. The second group received three sessions of DN for myofascial trigger points in the ABH muscle in addition to TSO exercise. Visual analog scale (VAS) (rest, activity) and foot function index (FFI) (pain, disability, activity) were used for clinical evaluation. Hallux valgus angle (HVA) and intermetatarsal angle (HVA) were measured. The evaluations were performed at baseline and at the first and fourth weeks following treatment. Results: VAS-rest baseline–fourth week and baseline–first week changes were significantly superior in the TSO-plus-DN group compared to the TSO group (p = 0.023, p = 0.039, respectively). FFI-disability baseline–fourth week change was significantly superior in the TSO-plus-DN group compared to the TSO group (p = 0.040). HVA and IMA baseline–fourth week changes were significantly superior in the TSO-plus-DN group compared to the TSO group (p = 0.001, p = 0.045, respectively). Conclusions: According to our findings, the combination of DN for the ABH muscle with TSO exercise may be recommended for the treatment of patients with mild-to-moderate HV. Full article

Background: The Lapidus procedure has become a cornerstone in the surgical management of hallux valgus, especially in cases with associated tarsometatarsal instability. This study investigated and compared the radiographic outcomes of three distinct Lapidus constructs, aiming to provide valuable insights into the optimal fusion configurations for achieving long-term stability improvement and maintaining the intermetatarsal angle (IMA) postoperatively. Methods: In this retrospective study, the objective was to assess and compare the outcomes of three different fusion constructs used in the Lapidus procedure: group 1, transverse screw fixation; group 2, metatarsal cuneiform screw fixation; and group 3, combined transverse and metatarsal cuneiform screw fixation. The study encompassed 32 feet: 11 in group 1, 8 in group 2, and 13 in group 3. The primary focus was to evaluate postoperative stability through radiographic imaging complemented by clinical assessments and an examination of complications. Statistical analyses were used to compare outcomes across the three fixation groups immediately, 3 months, 6 months, and 1 year postoperatively. Results: Radiographic assessments demonstrated successful fusion, and patients reported improvements in pain and function and overall satisfaction with the procedure. Complication rates were within an acceptable range. The IMA in all three groups exhibited a significant reduction postoperatively compared with preoperative measurements. Group 3 demonstrated a notably stronger initial reduction in the IMA compared with groups 1 and 2, and they maintained a statistically significantly more stable IMA value and exhibited a lower recurrence rate compared with the other two groups 1 year postoperatively. Conclusions: These findings endorse the use of Lapidus fusion with these three constructs, particularly with combined transverse and metatarsal cuneiform screw fixation, as a dependable and efficacious surgical approach in addressing hallux valgus with concomitant tarsometatarsal instability.

Background: Intrinsic foot muscle strengthening and orthotic devices such as toe spacers are commonly used to improve foot alignment and function. However, evidence regarding the combined effects of strengthening exercises and interdigital spacers remains limited. Objective: To examine whether adding a silicone toe spacer to a foot strengthening exercise program provides additional benefits compared with exercise alone. Design: Randomized controlled trial. Setting: University biomechanics laboratory. Participants: Twenty-five healthy adults (mean age 23.8 ± 1.3 years) without lower limb injury or neurological disorders were randomly allocated to one of two intervention groups. Interventions: Participants performed a six-week foot strengthening program (22 sessions). One group performed exercises alone, while the second group performed the same exercises while wearing a silicone interdigital toe spacer. Main outcome measures: The primary outcome was hallux valgus angle. Secondary outcomes included active and passive hallux range of motion (ROM), ankle dorsiflexion ROM (weight-bearing lunge test), navicular drop, and postural stability during single-leg stance assessed using center-of-pressure (CoP) measures. Results: Both groups demonstrated improvements over time in hallux valgus angle (p = 0.001, η² = 0.361), active hallux range of motion (p < 0.001, η² = 0.545), and ankle dorsiflexion (p < 0.001). However, no significant between-group differences were observed for the primary outcome or most secondary outcomes. A significant time × group interaction was observed only for passive hallux range of motion (p = 0.040, η² = 0.170), indicating greater improvement in the exercise-only group. Navicular drop and postural stability variables did not change significantly. Conclusions: A six-week foot strengthening program improved hallux alignment, hallux mobility, and ankle dorsiflexion in healthy adults. The addition of a silicone toe spacer did not provide additional short-term benefits compared with exercise alone. Full article

Background/Objectives: Foot impairments are common in older adults, but the independent associations of specific foot indices with locomotive syndrome (LS) severity remain unclear. We examined hallux valgus angle (HV), navicular height (NH), and passive ankle dorsiflexion (ADF). Methods: This cross-sectional study included 119 community-dwelling older adults classified into LS stages 0–3. Bilateral measures were summarized as maximum HV and minimum NH/ADF, reflecting the worst-affected side. Proportional-odds ordinal logistic regression modeled LS stage (0–3) with foot indices and covariates (age, sex, body mass index [BMI]). Extended models additionally adjusted for Timed Up and Go (TUG), gait speed, or single-leg stance (SLS). Sensitivity analysis used binary logistic regression (LS ≥ 2 vs. <2). Results: Greater ADF was independently associated with lower LS severity (OR per 1°, 0.91; 95% CI, 0.85–0.98; p < 0.01), whereas higher BMI was associated with greater LS severity (OR per 1 kg/m², 1.15; 95% CI, 1.01–1.30; p < 0.05). HV and NH were not significant. After adjustment for TUG, gait speed, or SLS, ADF remained inversely associated with LS severity (ORs, 0.92–0.93; p < 0.05), while the BMI association was attenuated. In binary logistic regression, greater ADF was associated with lower odds of LS ≥ 2 (OR per 1°, 0.85; 95% CI, 0.76–0.94; p < 0.005). Conclusions: Reduced passive ankle dorsiflexion is independently associated with greater LS severity, robust after accounting for key mobility and balance measures. Interventions targeting ankle mobility may represent a potentially modifiable factor and warrants confirmation in longitudinal and interventional studies. Full article

Background: The number of patients with rheumatoid arthritis (RA) undergoing forefoot arthroplasty has increased to better control the disease. Despite patients frequently expressing concerns regarding postoperative foot appearance and footwear-related expectations, no study has investigated postoperative changes in foot length and width in patients with RA. The aim of this study was to evaluate the effect of surgical procedures for rheumatoid forefoot deformities on variations in radiologically determined foot length and width. Methods: In total, 72 feet of 50 women and 3 men (average age: 66.7 years) underwent joint-preserving arthroplasty (n = 33) and arthrodesis of the first metatarsophalangeal joint with shortening osteotomy of the lesser metatarsals or resection arthroplasty of the lesser metatarsal heads (n = 39); procedures were carried out in our institute from August 2013 to February 2020. The mean disease duration was 23.5 years, and the average follow-up period was 17.5 months. Pre- and postoperative hallux valgus angle (HVA), intermetatarsal angle (IMA) of the first and second metatarsals (M1M2A), and IMA of the first and fifth metatarsals (M1M5A) were measured on weightbearing radiographs as well as foot length and width. We also evaluated the correlation between changes in radiographic parameters and variations in radiologically determined foot length and width. Results: Radiologically determined foot width changed significantly from 10.1 cm to 9.7 cm (p < 0.01), while no significant difference was found between pre- and postoperative radiologically determined foot length. HVA, M1M2A, and M1M5A were significantly improved after the surgery (p < 0.01, p < 0.01, and p < 0.01, respectively). A significant negative correlation was found between the variation in radiologically determined foot length and changes in HVA (r = −0.29, p = 0.02) and M1M5A (r = −0.23, p < 0.05), while a significant positive correlation was found between the variation in the foot width and changes in HVA (r = 0.34, p < 0.01), M1M2A (r = 0.55, p < 0.01), and M1M5A (r = 0.45, p < 0.01). There were no significant differences between operative procedures regarding variation in radiologically determined foot length and width. Conclusions: Surgical procedure for rheumatoid forefoot deformity improved radiographic parameters and reduced radiographic foot width while maintaining foot length. Full article

Background/Objectives: Flexible symptomatic flat foot in children can be surgically treated with calcaneus stop screws. This raises the question of whether pre- and postoperative radiographs (X-ray) can be analyzed in two planes using AI. Methods: In this monocentric retrospective study, angle measurements generated by Bone Metrics AI (Gleamer) were compared with manual measurements using Centricity™ (GE Healthcare). A total of 659 X-rays from 124 operated feet (2014–2024) were available, of which 422 were analyzable by AI and 299 met defined quality criteria. Bland–Altman plots were used to assess agreement. Linear and logistic regression analysis examined the influence of age, gender, accessory navicular bone, additional foot pathologies, and flat foot severity on comparability of the measurement methods and measurability by the AI. Finally, radiographs meeting and missing quality criteria were compared. Results: AI measurements were comparable to manual measurements for calcaneus inclination, hallux valgus, 1st–2nd and 1st–5th metatarsal angle both pre- and post-operatively. For the talus-1st metatarsal and medial arch angles, AI results differed significantly (p < 0.001 and p ≤ 0.013) from manual measurement. AI generated talus-1st metatarsal angle was measured larger by 6.14°, 95% [−7.14; −5.14] pre-operatively and 2.80°, 95% [−3.79; −1.81] post-operatively. Medial arch angle was smaller by 1.63° pre-operatively, 95% [1.03; 2.23] and 0.52° post-operatively, 95% CI [0.11; 0.93] with AI. Post-operative measurability was not significantly lower than pre-operative. AI measured angles on incorrectly taken radiographs as often or more often than on correctly taken ones. Discussion: Screw implantation did not negatively impair measurability or AI accuracy. However, age, gender, and flat foot severity influenced AI performance. Bad radiograph quality did not affect AI measurability negatively, indicating that AI cannot yet distinguish between X-rays suitable and unsuitable for angle measurements. Conclusions: Manual measurements are still indispensable in the diagnosis of children’s flat feet. In the future, continuous training of the AI is expected to bring it into line with manually measured radiological values. Full article

Background/Objectives: Hallux valgus (HV), a common foot deformity, is difficult to quantify beyond traditional angular measurements. This study introduces a novel dynamic distance mapping technique to visualize HV progression and identify spatial features linked to severity. Methods: A retrospective analysis of 335 feet from 178 patients undergoing HV surgery at Hasharon Hospital, Israel (2014–2024), utilized custom Python software to annotate 24 landmarks on preoperative standing anteroposterior radiographs. This generated 276 normalized Euclidean distances, analyzed via Pearson correlation against HV angles (HVA, IMA, DMAA, HIA). Results: Seven distances correlated negatively (r > 0.4, p < 0.05) and seven positively with HVA, involving the distal phalanx, sesamoids, and second metatarsal. Eleven distances showed strong positive correlation (r > 0.4, p < 0.05) with IMA, reflecting displacement patterns. Moderate correlations were observed with DMAA (six negative, r −0.3 to −0.4; two positive, r 0.3 to 0.4, p < 0.05) and HIA (two negative, r −0.3 to −0.4, p < 0.05). Visualizations highlighted progressive spatial changes. Conclusions: Dynamic distance mapping provides valuable insights into hallux valgus (HV) progression, as evidenced by significant correlations with HVA and IMA, supporting its potential role in surgical planning. However, its ability to capture 3D deformities requires validation against weightbearing computed tomography (WBCT). Future research should explore correlations with specific indications for corrective osteotomies to enhance clinical applicability. Full article

Background: Distal metatarsal chevron osteotomy is widely used in hallux valgus surgery, and many different osteotomy methods have been described in the literature because of its complications, such as nonunion, loss of reduction, and osteolysis. This study aimed to biomechanically compare the newly defined Parmaksızoğlu osteotomy and the distal chevron osteotomy. Methods: A total of 14 sawbone models were divided into two groups, and Parmaksızo
glu and distal chevron osteotomies were performed with the created incision guides. For biomechanical tests, fatigue testing was performed on the samples with 1,000 cycles of axial loading up to 10 N at a 15° angle. Rigidity, dorsal angulation, and deforming force values were recorded. Results: In the chevron osteotomy group, the average rigidity value of the 1,000th cycle was measured as 3.69 N/mm, the dorsal angulation value was 1.95°, and the average deforming force value was 20.14 N. In the Parmaksızo
glu osteotomy group, the average rigidity value of the 1,000th cycle was measured as 2.28 N/mm, the dorsal angulation value was 2.12°, and the average deforming force value was 26.72 N. Conclusions: In this study, Parmaksızo
glu osteotomy and chevron osteotomy were compared in terms of rigidity, dorsal angulation, and deforming force, and no statistically significant superiority of one technique over the other was observed. It has been statistically shown that the Parmaksızo
glu osteotomy, which has demonstrated a lower complication rate and a higher American Orthopaedic Foot & Ankle Society score in previous studies, has biomechanically similar features to the distal chevron osteotomy. Full article

Background: Correct use of the feet, step techniques, and positions constitute significant factors in the success of a dancer. Moreover, the type of dance has crucial effects on the posture of the foot and ankle. Therefore, the primary aim of our study was to determine whether there was a relationship between dancesport, dance experience (years), shoe-wearing time (hours), and shoe heel height (centimeters) in dance athletes performing Sportive Latin American Ballroom (SLAB) dance. Second, we aimed to compare the foot posture of SLAB dancers and nondancers with similar demographic characteristics. Methods: Twenty-six professional SLAB dancers and 26 nondancers who had similar demographic characteristics and did not use high-heeled shoes volunteered to take part in this study. Foot posture (using the Foot Posture Index [FPI]), foot pronation (using the navicular drop test [NDT]), tibiocalcaneal angle, hallux valgus angle (HVA) (using a goniometer), and ankle dorsiflexion range of motion (ROM) (using the weightbearing lunge test) were evaluated. Results: There was a positive moderate correlation between FPI score and shoe-wearing time on the dominant (P = .041; r = 0.40) and nondominant (P = .026; r = 0.43) sides. A positive very good correlation was found between shoe heel height and HVA (P < .001; r = 0.75). A negative good correlation was observed between years of dancing and nondominant ankle dorsiflexion ROM (P = .027; r = 20.43). When dancers and nondancers were compared, a statistically significant difference was found between FPI and NDT scores (P < .001). The FPI and NDT scores, tibiocalcaneal angle, HVA, and ankle dorsiflexion ROM were significantly greater in the dancer group compared with the nondancer group (P < .001) in all measurements of the dominant and nondominant sides. Conclusions: Revealing the relationship between dance experience and shoe-wearing time and the difference between the foot posture and deformities of athletes who perform SLAB dance and those of nondancers constitutes a pivotal endeavor that will increase awareness and knowledge among dancers and clinicians.

Background/Objectives: Juvenile hallux valgus (JHV) and flexible flatfoot (FFF) often coexist in children, yet their combined surgical management remains poorly explored. This study evaluates clinical and radiographic outcomes following a simultaneous approach using lateral hemiepiphysiodesis of the first metatarsal (LHFM) and calcaneal-stop (C-Stop) procedures in skeletally immature patients. Methods: A retrospective cohort of 24 bilateral patients (48 feet) aged 10–12 underwent LHFM and C-Stop between 2017 and 2023. Radiographic evaluation included Hallux Valgus Angle (HVA), Intermetatarsal Angle (IMA), Meary’s angle (MA), and transverse TaloCalcaneal (Kite’s) Angle (tTCA). The Foot and Ankle Disability Index (FADI) and the Tegner Activity Scale (TAS) were administered at the most recent follow-up and complications were recorded. Results: The mean follow-up was 3.7 years. Postoperative radiographs showed significant improvements in all parameters, with correction inversely correlated to baseline deformity severity. Full normalization of flatfoot parameters was achieved in 68.8% of feet, with mild residual deformity in the remainder. Males showed greater radiographic correction than females. IMA and HVA improved in most cases, reaching full normalization in 53.1% and 50% of feet, respectively. Clinically, all patients showed corrected hindfoot alignment and medial arch restoration; 90% achieved the maximum FADI score and 88% resumed recreational sports. Two cases of screw migration occurred, with one revision; no further complications were reported. Conclusions: Simultaneous correction of FFF and JHV using C-Stop and LHFM proved effective, yielding significant radiographic improvements and excellent functional outcomes in most cases, with minimal complications. However, full hallux alignment was achieved in only half of the cases, suggesting that additional distal metatarsal procedures may be needed for more severe deformities. Full article

Background/Objective: The recurrence of hallux valgus (HV) after primary surgical correction remains a clinical challenge, often requiring combined approaches to address both bony realignment and soft tissue imbalance. While locking plates have shown some biomechanical advantages in HV correction, evidence regarding their application in revision procedures is limited. This study presents a retrospective single-surgeon experience with a small cohort, aiming to describe radiographic and functional outcomes and to share practical insights rather than provide definitive conclusions. Methods: In this retrospective case series, patients undergoing revision surgery for failed HV correction over the past ten years at a single tertiary institution were analyzed. Radiographic parameters—hallux valgus angle (HVA), intermetatarsal angle (IMA), distal metatarsal articular angle (DMAA), and sesamoid position—were assessed. Functional outcomes included the American Orthopaedic Foot and Ankle Society (AOFAS) score and the Visual Analog Scale for pain. Surgical strategies were tailored according to recurrence mechanisms, and some cases involved Wilson osteotomy with intramedullary plate fixation. The Mann–Whitney U test and the Wilcoxon signed-rank test were applied to assess efficacy. Results: A total of 11 feet treated by one surgeon were included. Both soft tissue procedures and combined osteotomy with intramedullary plate fixation led to statistically significant but preliminary improvements in HVA, IMA, DMAA, and sesamoid alignment. Functional scores improved, and the complication rate was within the range reported in the previous literature. Conclusions: This retrospective single-surgeon study with a limited sample size suggests that Wilson osteotomy combined with intramedullary plate fixation may represent a joint-preserving and biomechanically supportive option for recurrent HV, particularly in cases with large DMAAs and severe sesamoid displacement. However, the findings should be interpreted cautiously given the small cohort, retrospective design, and absence of multi-angle radiographic visualization. The results highlight a potential approach in specific clinical settings rather than a definitive solution. Larger, prospective, multi-center studies are required to confirm long-term utility.

Objectives: This study aimed to compare the clinical, functional, and radiological outcomes of three different fixation techniques—dorsal locking plate, crossed cortical screw, and a combination of both—used in first metatarsophalangeal (MTP) joint arthrodesis for advanced-stage hallux rigidus. The goal was to provide evidence-based guidance for surgical technique selection. Methods: This retrospective cohort study included 52 patients with advanced hallux rigidus (stage III–IV, Coughlin–Shurnas classification) who underwent surgical treatment between 2023 and 2025 at the Department of Orthopedics and Traumatology of Ankara Etlik City Hospital, with a minimum follow-up of one year. Patients were categorized into three groups according to the fixation technique used. Visual Analog Scale (VAS), American Orthopaedic Foot & Ankle Society (AOFAS) score, and Foot Function Index (FFI) were assessed using validated Turkish-language versions of the questionnaires. Radiological parameters included hallux valgus angle, first toe dorsiflexion angle, distal interphalangeal (DIP) arthritis, and radiographic union—defined as trabecular bridging across at least three cortices on weight-bearing anteroposterior and lateral radiographs. ANCOVA was performed with age as a covariate. Results: A total of 52 patients were included: Group 1 (dorsal plate fixation, n = 19), Group 2 (crossed cortical screw fixation, n = 16), and Group 3 (combined fixation, n = 17). Group 1 patients were significantly older (mean age: 64 ± 6 vs. 55 ± 6 and 59 ± 5 years; p < 0.001). After age adjustment, VAS pain scores were significantly higher in Group 1 compared to Group 3 (mean VAS: 2.8 ± 0.6 vs. 1.9 ± 0.5; p = 0.010). AOFAS scores did not differ significantly (p = 0.166), although Group 2 showed the highest median value (90 [70–93]). FFI scores differed significantly (p < 0.001), with Group 1 reporting worse outcomes (19 [17–31]) than Group 2 (15 [13–22], p = 0.03) and Group 3 (15 [11–16], p = 0.01). Dorsiflexion angle was significantly lower in Group 2 than Group 1 (median 19° vs. 27°; p = 0.04), though all remained within the physiological range. Radiographic union was achieved in 50/52 patients (96.2%), without significant intergroup differences (p = 0.612). Complications included two cases of wound dehiscence in Group 1; no infections, symptomatic non-union, malalignment, or hardware irritation were observed. Conclusions: Crossed cortical screw fixation yielded the most favorable functional outcomes, whereas the combined technique achieved the lowest postoperative pain scores. Dorsal plate fixation alone consistently underperformed. While outcomes were adjusted for age, residual confounding cannot be excluded. These results highlight the importance of tailoring fixation strategy to patient profile, with crossed screw and combined methods representing reliable choices for optimizing postoperative outcomes in advanced hallux rigidus.

Background: Foot deformities, particularly hallux valgus, significantly impact patients’ quality of life. Conventional radiographs are essential for their assessment, but manual measurements are time-consuming and variable. This study assessed the reliability of a deep learning-based solution (Milvue, France) that automates podiatry angle measurements from radiographs compared to manual measurements made by radiologists. Methods: A retrospective, non-interventional study at Perpignan Hospital analyzed the weight-bearing foot radiographs of 105 adult patients (August 2017–August 2022). The deep learning (DL) model’s measurements were compared to those of two radiologists for various angles (M1-P1, M1-M2, M1-M5, and P1-P2 for Djian–Annonier, calcaneal slope, first metatarsal slope, and Meary–Tomeno angles). Statistical analyses evaluated DL performance and inter-observer variability. Results: Of the 105 patients included (29 men and 76 women; mean age 55), the DL solution showed excellent consistency with manual measurements, except for the P1-P2 angle. The mean absolute error (MAE) for the frontal view was lowest for M1-M2 (0.96°) and highest for P1-P2 (3.16°). Intraclass correlation coefficients (ICCs) indicated excellent agreement for M1-P1, M1-M2, and M1-M5. For the lateral view, the MAE was 0.92° for calcaneal pitch and 2.83° for Meary–Tomeno, with ICCs ≥ 0.93. For hallux valgus detection, accuracy was 94%, sensitivity was 91.1%, and specificity was 97.2%. Manual measurements averaged 203 s per patient, while DL processing was nearly instantaneous. Conclusions: The DL solution reliably automates foot alignment assessments, significantly reducing time without compromising accuracy. It may improve clinical efficiency and consistency in podiatric evaluations. Full article

Background/Objectives: Akin osteotomy, in the context of corrective surgery for hallux valgus, is an effective tool available to surgeons. However, few studies have thoroughly investigated the anatomical and technical characteristics to be considered in order to perform an optimal osteotomy. This cross-sectional observational study aims to identify the ideal site for performing Akin osteotomy and to identify the factors that influence its corrective power. Methods: To this end, an analysis was conducted on a random sample of 100 patients (186 feet) who underwent X-rays without surgical treatment. Variations in the width between the metaphysis and diaphysis were measured at five different points. For each cut level, corresponding to wedge bases of 2, 3 and 4 mm, three corrective angles were calculated. In addition, the distance between the cut line and the joint was recorded. Results: The base width ranged from 12.6 to 23.2 mm, showing greater variability in the metaphyseal region. The corrective power of the osteotomy showed wide variability, ranging from 5.9 to 18.4 degrees. Four determining factors emerged: the width of the base, the inclination of the medial cortex, the height at which the cut is made and the thickness of the wedge of bone removed. The data obtained suggest that osteotomy should not be performed less than 10 mm from the joint line to avoid the risk of joint invasion. Conclusions: In conclusion, there is no universally ideal site for performing an Akin osteotomy: the choice depends on the degree of correction desired, which in turn is influenced by the factors identified in the study.

Background: Weight gain during pregnancy, loosening of the foot ligaments with relaxin hormone release, and anthropometric and biomechanical changes can be seen in the foot with the growing fetus. We sought to determine whether these pregnancy-related changes cause painful musculoskeletal problems by altering the proximal structures of the lower extremities and the structure of the spine. Methods: Both feet of 210 women (half in the third trimester of pregnancy) aged 18 to 40 years with similar demographic characteristics were evaluated by measuring navicular drop, hallux valgus angle, foot width, foot length, and tibiocalcaneal angle. Foot Function Index for foot-ankle, Kujala Patellofemoral Score for knee, Western Ontario and McMaster Universities Osteoarthritis Index for hip, Oswestry Disability Index for waist, and Modified Neck Disability Index for neck were used to determine pain and functional limitation. Results: Pain and functional disability in the waist, hip, knee, and foot-ankle joints; navicular drop; hallux valgus angle; and tibiocalcaneal angle were significantly higher in pregnant women versus the control group (P < .001). Pain and dysfunction in all of the joints increased as navicular drop increased in pregnant and nonpregnant women. In addition, the increase in other anthropometric measurements in both groups was determined to caused pain and functional disability in most of the women, especially in foot-ankle joints. However, the cause of joint pain and functional deficiencies was unrelated to pregnancy. Conclusions: Foot deformities and proximal region complaints were significantly higher in pregnant women, and foot deformities caused more foot-ankle pain and disability in both groups. No difference was observed in pregnant women versus the control group. Full article
