Tibialis anterior tendon tear is an uncommon injury. Nontraumatic or degenerative tears are usually seen in the avascular zone of the tendon. Treatment can be conservative or surgical. Conservative treatment is adequate for low-demand older patients. For active patients, surgical treatment can be challenging for the surgeon because after debridement of degenerative tissue, a gap may be formed t...

Introduction Banked allogeneic bone grafts have been used widely in clinic for the repair of bone defects. Massive allografts are thought to function through an osteoconductive pathways, demineralized bone was reported to be osteoinductive. Morselized allograft which has been used to fill bony defects in revision arthroplasty to fulfill a mechanical role, as well as to provide a scaffold for ne...

Background There is no consensus regarding the best method of reconstruction in pediatric population following the wide resection of malignant bone tumors. More exploration of the complications of osteoarticular reconstruction leads to less existing controversy of this type of reconstruction, which is the main point of this article. Methods Long-term outcomes and complications of osteoarticul...

Hydatid disease is caused by the parasitic tapeworm Echinococcus granulosus. Osseous involvement accounts for 0.5% to 4% of cases in humans. Patients usually are from endemic zones and are initially asymptomatic, presenting with pain and edema at a later stage of disease. However, large lesions may present initially as pathologic fractures. Standard radiographs usually show expansive osteolytic...

OBJECTIVES The purpose of this study was to compare union rates for isolated subtalar arthrodesis with and without the use of bone grafts or bone graft substitutes. METHODS We retrospectively reviewed 135 subtalar fusions with a mean follow-up of 18 ± 14 months. The standard approach was used for all surgeries. Graft materials included b-tricalcium phosphate, demineralized bone matrix, iliac ...

INTRODUCTION Achieving solid implant fixation to osteoporotic bone presents a challenge to both spinal surgeons and hardware designers. Loss of surgical construct stability as a result of screw loosening is a well-known complication [1,2], particularly in patients with poor bone quality [3,4]. Thus, the development of novel strategies to address the issue of obtaining enhanced bone-to-screw pur...

UNLABELLED INTRODUCTION Interprosthetic fractures of the humerus are rare. Revisions of total elbow arthroplasty components in these cases are difficult. We report the first case of a patient with hemophilia who underwent a revision with a tibial allograft prosthetic composite without the need for hardware augmentation. CASE PRESENTATION A 43-year-old Caucasian man with a history of hemoph...

STUDY DESIGN This was a biomechanical push-out testing study using a porcine model. OBJECTIVE The purpose was to evaluate the strength of implant-bone interface of a porous titanium scaffold by comparing it to polyetheretherketone (PEEK) and allograft. SUMMARY OF BACKGROUND DATA Osseointegration is important for achieving maximal stability of spinal fusion implants and it is desirable to ac...

INTRODUCTION Performing intercalary segment reconstruction after malignant bone tumour resection results in both mechanical and biological challenges. Fixation must be solid enough to avoid short-term or mid-term mechanical failure. The use of an allograft or autograft must ensure long-term survival of the reconstruction. The goal of this study was to analyse the clinical and radiological outco...
