PURPOSE This study was performed to compare the minimal 2-year outcome of anterior cruciate ligament (ACL) reconstruction using bone-patellar tendon-bone (BPTB) allografts versus autografts, both augmented with an iliotibial band tenodesis. TYPE OF STUDY Retrospective review. METHODS Forty-six of 52 BPTB ACL reconstructions using allografts and 33 of 37 BPTB ACL reconstructions using autogr...

There are many different surgical techniques for bone reconstruction. However, biological reconstruction methods are being increasingly developed. The main purpose is not only to fill up defects, but stimulate the processes of and regeneration of as a complete organ. In this report, we describe basic principles of orthobiology essential orthobiological materials. A clinical case presented where...

INTRODUCTION Perioperative irradiation is often combined with spine tumor surgery. Radiation is known to be detrimental to healing process of bone fusion. We tried to investigate bone fusion rate in spine tumor surgery cases with perioperative radiation therapy (RT) and to analyze significant factors affecting successful bone fusion. METHODS Study cohort was 33 patients who underwent spinal t...

considering the importance of bone augmentation prior to implant placement in order to obtain adequate bone quality and quantity, many studies have been conducted to evaluate different techniques and materials regarding new bone formation. in this study, we investigated the bone healing capacity of two different materials deproteinized bovine bone mineral (dbbm with the trade name of bio-oss) a...

BACKGROUND Ridge preservation was developed as a therapy to prevent severe bone resorption after tooth extraction. The purpose of this study is to determine if there is any difference in the amount of new bone formation ≈3 months after extraction and ridge preservation compared to that after ≈6 months. METHODS Minimally traumatic extraction with ridge preservation using mineralized human bone...

Previous studies documented the use of fibular allograft in the treatment of slipped capital femoral epiphysis (SCFE) with bone graft epiphysiodesis (BGE). This study describes the results of using a 10-mm diameter premilled fibular allograft packed with demineralized bone matrix placed across the physis in an open surgical approach under image intensification. A review identified 45 cases of B...

PURPOSE To report the outcome of revised total hip arthroplasty procedures involving an anterior cortical window, extensive strut allografts, and an Exeter impaction graft. METHOD Eight patients (9 hips) with a mean age of 58 years underwent revision of total hip arthroplasty using the Exeter hip impaction graft system and strut allografts between 1995 and 1998. An extensile anterior approach...

A technique for single-tooth sinus lift and simultaneous implant placement in the posterior maxilla is presented. Ten hydroxyapatite-coated cylindric implants, 13 to 15 mm in length, were placed together with a composite bone graft of demineralized freeze-dried bone allograft and autogenous bone in 10 adults. Surgical technique and anatomic considerations are discussed. Follow-up of 3 years sho...

As long as bone repair and regeneration is considered as a complex clinical condition, the administration of more than one factor involved in fracture healing might be necessary. The effectiveness or not of bone morphogenetic proteins (BMPs) in association with other growth factors and with mesenchymal stem cells in bone regeneration for fracture healing and bone allograft integration is of gre...
