BACKGROUND Failed total ankle arthroplasty (TAA) often results in significant bone loss and requires salvage arthrodesis. This study quantified the bone loss following failed TAA and reports the outcome of seven arthrodesis reconstructions using the Ilizarov method. METHODS A retrospective review of ankle fusions was performed for failed TAA to collect the mode of implant failure, presenting ...

This study tested the hypothesis that use of biomaterials in distraction osteogenesis (DO) would reduce the treatment time and enhance bone formation quality. A 1.0-cm tibial shaft was removed in the left tibia of 36 rabbits. Rabbits were randomly divided into three groups: group A, the defect gap was reduced with the tibia shortened for 1.0-cm; group B, the defect gap was filled with 1.0-cm re...

BACKGROUND Management of post trauma tibia bone gap varied with orthopedic surgeons' experience and tools available. Study aims to determine predictive factors for distraction by a monotube fixator (DMF) outcome in post tibia trauma limb length discrepancy. METHODS A prospective descriptive cross sectional study of post traumatized tibia bone gap and limb length discrepancy patients at tertia...

The effect of increased distraction rate on bony tissue differentiation was studied using a paired bilateral model of rat femur lengthening. After a 6-day latency period, one randomly selected femur for each rat was distracted at 0.5 mm/day (normal rate) for 12 days, and the contralateral femur was distracted at 1.5 mm/day (increased rate) for 4 days. Femoral lengthening for each side was 6.0 m...

Some replantation cases require substantial bone shortening for primary closure. Leg-length discrepancy can be restored by lengthening of the replanted or revascularized extremities. Between 1991 and 2000, four patients with four total and two subtotal below-knee amputations had replantation or revascularization for their severely damaged extremities. All of them had extensive debridement, vasc...

Received August 6, 2003 Abstract Achondroplasia and hypochondroplasia limb lengthening has become better accepted over last thirty years. We studied our experience on all limb lengthening for short stature over the last ten years. We reviewed patient records, X-rays and Dual Energy X-ray Absorptiometry (DEXA) scans to evaluate the changes in body proportion after limb lengthening and the compli...

Congenital pseudarthrosis of tibia (CPT) is still a condition extremely difficult to treat in the field of paediatric orthopaedics. Ilizarov technique, free fibular bone graft, Charnley-Williams method [1] are the current treatment options achieving reasonable fusion rate. The solid bone fusion is the most difficult problem to treat. Limb length discrepancy (LLD) is one of the adjacent problems...

OBJECTIVES Lengthening osteotomies of the calcaneus in children are in general grafted with bone from the iliac crest. Artificial bone grafts have been introduced, however, their structural and clinical durability has not been documented. Radiostereometric analysis (RSA) is a very accurate and precise method for measurements of rigid body movements including the evaluation of joint implant and ...

Objectives. We evaluated the results of digital lengthening by distraction and second-stage bone graft. Methods. We treated finger deficiency of 201 digits in 104 patients (68 males, 36 females) by digital distraction and second-stage bone graft. The distraction was performed with a rate of 1 mm/day (for the first ten days) and 0.5 mm/day followed by using a self-designed bilateral tubal-helica...

Chronic alcohol abuse decreases bone mass, inhibits osteoblast differentiation and function, increases fracture incidence, and delays fracture healing. Four studies were designed to use intragastric ethanol delivery as part of a total enteral nutrition (TEN) system to determine the negative systemic effects of chronic ethanol on 1) the rat skeleton and 2) local rapid bone formation during limb ...
