Special Issue Information

Dear Colleagues,

Bone defects still represent a major challenge for orthopedic and trauma surgeons. They are serious complications that are most commonly caused by trauma, tumor, infection, and failed arthroplasty or congenital musculoskeletal disorders. Bone defects entail a sustained increase in hospitalization, risk of complications, and associated increase in expenses. Skeletal reconstruction of bone defects is challenging and can be lengthy with often unpredictable outcomes.

Surgical management aims to reconstruct the bone defect, avoiding amputation and providing acceptable functional outcomes. The most common and widely accepted procedures are, e.g., the vascularized bone-free transfer and Ilizarov bone transport techniques.

The healing of bone defects is a well-orchestrated physiological process involving multiple cell types and signaling molecules interacting at the fracture site to replace and repair bone tissue without scar formation. In the case of a bone nonunion, the implantation of, e.g., biomaterials as defect-filler-like scaffolds for repairing these defects and bone regeneration, respectively, is essential.

This Special Issue aims to detail the latest progress and research in treating bone defects, touching on biomechanics, implants, biomaterials, and clinical outcomes. 

We welcome submissions of original research and comprehensive review perspectives, including, but not limited, to the following fields:

  • Bone and fracture biomechanics;
  • Bone healing;
  • Critical size bone defects;
  • Fracture non-union;
  • Inflammation;
  • Joint arthroplasty and fracture osteosynthesis;
  • Implant designs;
  • Materials proprieties;
  • Patient selection;
  • Primary and revision settings.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Life is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Cartilage repair techniques for chondral defects in the hip are crucial for treating conditions like femoroacetabular impingement, developmental dysplasia, and osteonecrosis, especially in young patients to delay the progression of osteoarthritis. This study aims to present age and sex distributions and trends in hip-preserving surgeries in Germany from 2006 to 2022, analyzing 116,179 procedures using the German OPS coding system. The procedures were categorized into three groups: debridement, refixation, and regeneration. Arthroscopy was more common than arthrotomy (98,916 vs. 17,263). Males underwent more procedures than females (63,771 vs. 52,408). Debridement had a monomodal age distribution peaking at 43.42 years, while refixation and regeneration exhibited bimodal patterns. Regenerative procedures were primarily performed on younger patients (average 27.73 years). A Joinpoint analysis showed an initial increase in procedures, peaking around 2013, followed by a decline. Arthroscopic procedures peaked at approximately 9000 in 2013, whereas arthrotomies peaked at around 1200 after 2014. The decline in procedures post-2013 may reflect refined surgical indications and a shift towards outpatient settings. These findings underscore the trend towards minimally invasive, scaffold-based treatments, with regenerative techniques showing promising outcomes in younger patients. Future research should focus on prospective comparative studies and cost–benefit analyses to guide clinical decision-making. Full article
