Unlabelled: Purpose/Aim of the study: The purpose of this analysis was to compare the clinical outcomes of vertebral fusion with allograft versus autograft bone.
Materials And Methods: Medline, PubMed, Cochrane, EMBASE, and Google Scholar databases were searched until July 27, 2015 using the keywords: lumbar vertebrae, surgery, spondylolisthesis, bone transplantation, allograft, autograft. Inclusion criteria were randomized controlled trials (RCTs), two-arm prospective studies, retrospective studies, and cohort studies comparing the results of autograft and allograft in patients receiving lumbar spinal fusion. The outcomes were changes of Oswestry Disability Index (ODI) and visual analogue scale (VAS) pain scores from baseline at 1, 2, and 3 years after surgery and fusion rates.
Results: Of 154 studies identified in the database searches, five were included in the quantitative analysis (one RCT, one prospective, and three retrospective studies). The mean patient age ranged from approximately 40 to 65 years, and approximately half of the patients were males. The total number of patients who received allografts was 333 and the total that received autografts was 175. The analysis revealed the change of ODI and VAS pain score at 1, 2 and 3 years was similar between the allograft and autograft groups (all, p > .05), as were the fusion rates (p > .05).
Conclusions: Both allograft and autograft provide acceptable outcomes for spinal fusion.

Comparison of Dynamic Postural Stability in Autografts Versus Allografts Following Anterior Cruciate Ligament Reconstruction With Remnant Preservation: A Prospective Study With 1-Year Follow-up.

Background: Graft selection is an important part of preoperative planning for anterior cruciate ligament reconstruction (ACLR). In addition, ACLR with the remnant preservation technique has recently gained attention due to potential benefit in bone-tendon healing, graft revascularization, and proprioceptive nerve remodeling. However, the ideal graft choice remains controversial, and there is limited research comparing autograft and allograft in ACLR with remnant preservation.

Background: Anterior cruciate ligament (ACL) tears are frequent injuries in athletes that often require surgical reconstruction so that patients may return to their previous levels of performance. While existing data on patient-reported outcomes are similar between bone-patellar tendon-bone (BTB) and hamstring tendon (HT) autografts, the literature regarding return to sport (RTS), return to previous levels of sport activity, and graft failure rate remains limited.
Purpose: To compare rates of RTS, return to previous activity levels, and graft retears among athletes undergoing primary ACL reconstruction using a BTB versus HT autograft.

Bone defects are difficult to treat clinically and most often require bone grafting for repair. However, the source of autograft bone is limited, and allograft bone carries the risk of disease transmission and immune rejection. As tissue engineering technology advances, bone replacement materials are playing an increasingly important role in the treatment of bone defects.

Background: This study aims to compare the complications and satisfaction associated with favorable allografts, Fresh Frozen Rib Graft (FFRG) and Irradiated Homologous Costal Cartilage (IHCC), in revision rhinoplasty.
Methods: The PRISMA guidelines were adhered to in the conduct of this systematic review. No limitations were applied to the types of studies included.
Long-term outcome after a limb salvage procedure using a femoral head allograft following the resection of a synovial sarcoma affecting the hindfoot.

The hindfoot is an uncommon site for malignant tumours. While limb salvage procedures are now more common for treating bone sarcoma, there is limited information available on hindfoot reconstruction alternatives because of its low incidence and its challenging outcomes. We present a case report of a man in his late 60s with synovial sarcoma affecting the right heel (calcaneus and soft tissue).
