We reviewed the results of distraction osteogenesis of 114 femora and 147 tibiae that had been lengthened to treat a variety of diagnoses. The femora had been lengthened an average of eleven centimeters (range, 3.5 to 17.0 centimeters), or 48 per cent (range, 8 to 86 per cent) of the original femoral length. The average total time for the treatment of the femora (use of the fixator and any subs...

BACKGROUND Long-term application of an external fixator to treat leg-length discrepancy and short stature often causes complications, such as pin-tract infection or loss of range of motion at the knee or ankle (or both). Prolonged fixator use also interferes with the activities of daily living. To minimize such problems, we have combined intramedullary nailing with external fixation. Using this...

Although single-loop tibialis tendon allografts have increased in popularity owing to their many advantages over patellar tendon and double-loop hamstring tendon autografts, some percentage of the patient population do not have clinically stable knees following anterior cruciate ligament reconstruction with single-loop tibialis tendon allografts. Therefore, it would be advantageous to determine...

An increase in anterior laxity following reconstruction of the anterior cruciate ligament (ACL) can result from lengthening of the graft construct in either the regions of fixation and/or the region of the graft substance between the fixations. RSA could be a useful technique to determine lengthening in these regions if a method can be devised for attaching radio-opaque markers to soft tissue g...

Introduction We have developed a novel cell therapy using culture expanded bone marrow cells (BMC) and platelet rich plasma (PRP) in lower limb lengthenings and demonstrated that transplantation of BMC and PRP into the distracted callus shortened the treatment periods and reduced associated complications by accelerating new bone regenerates. Favorable clinical outcome was observed especially in...

INTRODUCTION This is a case report of extreme lengthening of the tibia of about 14.5cm using bone transport technique following road traffic accident trauma to the lower limbs. The management of the subsequent massive skeletal defects was challenging to orthopedic surgeons. Based on reported cases, the highest tibial lengthening was 22cm using bifocal transport, while the highest unifocal tibia...

BACKGROUND Distal tibial reconstruction with use of an external fixator when there is bone loss, limb-length discrepancy, and/or ankle instability is associated with many problems. The technique of limb-lengthening, ankle arthrodesis, and segmental transfer over an intramedullary nail has been introduced to overcome these problems. The present study investigates this combined technique. METHO...

There are many techniques for limb lengthening. Lengthening over a plate is an alternative choice of fixation in children or when nailing is difficult. We present a new technique for tibial lengthening with using a monolateral external fixator over a lengthening plate.Lengthening over an intramedullary nail is a commonly used method in patients with short stature or limb-length discrepancy. How...

BACKGROUND and purpose Limb lengthening is performed for a diverse range of orthopedic problems. A high rate of complications has been reported in these patients, which include motor and sensory loss as a result of nerve damage. We investigated the effect of limb lengthening on peripheral nerve function. PATIENTS AND METHODS 36 patients underwent electrophysiological testing at 3 points: (1) ...
