OBJECTIVE To compare the fusion rate of a hydroxyapatite demineralized bone matrix (DBM) with post-laminectomy acquired autograft in lumbar interbody fusion surgery and to evaluate the correlation between fusion rate and clinical outcome. METHODS From January 2013 to April 2014, 98 patients underwent lumbar interbody fusion surgery with hydroxyapatite DBM (HA-DBM group) in our institute. Of t...

INTRODUCTION The aim of the study was to compare and analyze retrospectively the outcomes of arthroscopic posterior cruciate ligament reconstruction with autograft versus allograft. MATERIAL AND METHODS Seventy-one patients who underwent arthroscopic posterior cruciate ligament reconstruction with an autograft or allograft met our inclusion criteria. There were 36 patients in the autograft gr...

OBJECTIVE To compare the behavior of a tissue-engineered living skin equivalent (LSE) with an autograft in acute donor site wounds. DESIGN Paired-comparison, randomized control trial. SETTING A university dermatology service. PATIENTS Three donor sites were created on the anterior thigh of each of 20 patients requiring split-thickness skin grafts. INTERVENTION For each patient, the dono...

STUDY DESIGN A retrospective study. PURPOSE To investigate clinical and radiological outcomes when using spinous process as a tricortical autograft for segmental spinal fusion in transforaminal lumbar interbody fusion (TLIF). OVERVIEW OF LITERATURE Interbody spinal fusion is one of the important procedures in spinal surgery. Many types of autografts are harvested at the expense of complicat...

Pulmonary autograft valve replacement has been simulated by implanting the pulmonary valve into the aortic position of the same cadaver heart from both human and porcine sources. The forces acting on the pulmonary valve leaflets have been calculated on the basis of a triaxial ellipsoid mathematical model. These forces on the pulmonary autograft valve were shown to be essentially similar to thos...

BACKGROUND CONTEXT Conditions requiring posterior lumbar spinal fusion remain a clinical challenge. Achieving arthrodesis using autogenous bone graft is inconsistent when rigid internal fixation such as transpedicular instrumentation is applied. Synthetic materials, particularly calcium phosphate-based ceramics, have shown promise for spine fusion applications, especially when combined with aut...

Introduction. Although several intercalary reconstructions after resection of a lower extremity malignant bone tumor are reported, there are no optimal methods which can provide a long-term reconstruction with fewest complications. We present the outcome of reconstruction using a devitalized autograft and a vascularized fibula graft composite. Materials and Methods. We conducted a retrospective...

PURPOSE To investigate tibial tunnel widening and knee instability after ACL reconstruction with hamstring autograft or irradiated soft tissue allograft. METHODS Eight-two patients were divided into two groups: autograft group and allograft group. Radiographic and clinical evaluations were performed. RESULTS Seventy patients were followed up with median of 36.3 months (range 36-38 months). ...
