Reconstruction of the anterior cruciate ligament:a comparison between bone-patellar tendon-bone grafts and four-strand hamstring grafts
Background :Disruption of anterior cruciate ligament (ACL) is a common ligamentous injury of the knee. The choice of graft for (ACL) reconstruction remains controversial. This prospective, randomized clinical trial aimed to compare clinical results of bone-patellar tendon-bone (BPTB) grafts and four-strand semitendinosus-gracilis (ST) grafts for ACL reconstruction over a 3-year follow-up inte...
متن کاملRevascularisation of bone grafts in rats.
Revascularisation of syngeneic and allogeneic intramuscular bone grafts have been studied using radioactive microspheres to measure the ingrowth of blood vessels. New bone formation and resorption were measured by 85strontium uptake and by graft weight reduction. Revascularisation, and mineralisation rate were significantly higher in syngeneic grafts than in allogeneic grafts at two, three and ...
متن کاملEffects of laser Therapy on Morselized Bone Allograft Incorporation Laser Therapy and Bone Grafts Incorporation
Objective: To assess the effect of low-level laser therapy (LLLT) on morselized bone allograft incorporation. Material and Methods: Four rabbits were used as bone tissue donors. Morselized bone allografts and autografts were placed into the calvaria of 20 rabbits divided across four groups: two LLLT groups (allograft, autograft and blood clot) and two non-irradiated control groups (allograft, a...
متن کاملEffect of extracorporeal irradiation on segmental bone autograft incorporation in Sprague-Dawley rats
Latar belakang: Autograft tulang digunakan pada operasi rekonstruksi kasus tumor tulang. Extracorporeal irradiation (ECI) pada tulang digunakan untuk membunuh sel tumor. Namun radiasi juga menimbulkan efek negatif terhadap osteoinduksi dan osteogenensis untuk inkorporasi autograft tulang. Penelitian ini bertujuan mempelajari pengaruh iradiasi dengan dosis 50-300 Gy terhadap kemampuan inkorporas...
متن کاملInfluence of extracorporeal irradiation on the reintegration of autologous grafts of bone and joint. Study in a canine model.
We studied the effects of irradiation on the reintegration of autologous osteoarticular grafts over a period of 24 weeks in a canine model. In 16 foxhounds the medial femoral condyle was resected, irradiated and immediately replanted. In the control group resection and replantation were performed without irradiation. Reintegration was assessed by macroscopic analysis, histology, radiography and...
