Application of bovine bone versus bovine DBM graft on bone healing of radial defect in rat

AbstractReconstruction of the fractured bone and bone healing biology is compound processes, and the effectiveness of osteosynthesis is determined by their success. Currently, autografts or allografts and mineral bone substitutes are used commonly for skeletal restoration. The aim of this study is to evaluate the effects of bovine demineralized bone matrix (DBM) and bovine bone (bovine xenografts) on the bone healing process in rat. Sixteen female Sprague-Dawley rats were used in separate four groups: autograft (positive control,n = 4), untreated defect (negative control,n = 4), bovine DBM (n = 4), and bovine bone graft (n = 4). Radiological, histopathological, and biomechanical evaluations were done during the study, and results were recorded and analyzed statistically. At the 56th postoperative day, there was no significant differences in different groups in the biomechanical and radiographical criteria (P >  0.05), but there were significant differences in the mode of union and cancellous bone formation between the groups in histopathological evaluation at the 56th postoperative day (P

This study aimed to analyze cervical alignment after single-level ACCF using autologous bone graft without spinal instrumentation for CPS compared with that for CDD.MethodsSix patients underwent single-level ACCF using autologous bone graft without spinal instrumentation for CPS. The control group included 18 age-matched patients who underwent single-level ACCF using autologous bone graft for CDD without spinal instrumentation for the same duration. Cervical and lateral plain radiographs and computed tomography scans were taken. The Frankel classification was used to assess the neurological status preoperatively, postopera...

We present the case of a 31-year-old male with debilitating post-traumatic arthritis of the ankle secondary to osteonecrosis of the tibial plafond. He was treated with a custom-cut tibial osteochondral allograft transplantation. At 1-year follow-up, radiographs confirmed incorporation of the graft. He had demonstrated significant improvement in terms of both subjective pain and functionality of the ankle and was ready to return to work. Our observation in this case suggests that osteochondral allograft implantation may be a viable alternative treatment in cases of ankle arthritis in the younger patient.

Conclusion: Our data showed that the new allograft cage is superior to the PEEK cage in providing a high fusion rate and fewer complications after 1-level and 2-level ACDF procedures. It may represent an excellent alternative to other cages.

AbstractPurposeBone tunnel widening following anterior cruciate ligament reconstruction (ACLR) is well documented, although the aetiology and clinical significance of this phenomenon remain unclear. At mid-term follow-up, a greater prevalence of tunnel enlargement has been reported with the use of hamstring (HS) grafts. However, there are paucity of data on what happens in the longer term. The aim of this study was to assess the change in femoral and tibial tunnel dimensions 15  years after four-strand HS ACLR.MethodsThis is a retrospective review of 15 patients who underwent arthroscopic ACLR using HS autograft tendo...

Structural glenoid bone grafting in reverse total shoulder arthroplasty (RSA) has previously been reported to have good functional outcomes and low complication rates. We have observed different complication rates and hypothesized that baseplate fixation and severity of deformity may be predictors of early failure.
