RATIONALE The treatment of osteogenesis imperfecta (OI) requires a multidisciplinary approach to maximize function and reduce fracture incidence. The aim of this case report was to discuss an alternative surgical approach to stabilize a corrective osteotomy using the Fassier Duval (FD) system in an OI patient. PATIENT CONCERNS A 20-year-old OI woman presented with left thigh pain, gait distur...

Distal radial physis closure in children can develop severe wrist deformity (radial shortening). These patients can be treated using a single-step surgery. It was carried out in the form of a corrective osteotomy adopting the volar approach, with fixed-angle volar plate fixation and bone grafting from the iliac crest. There have been few descriptions of the use of this technique in the manageme...

Certain deformities of the hip joint seem to predispose the hip to the development of osteoarthrosis. Successful surgical correction of these deformities before the onset of osteoarthrosis requires accurate characterization of the anatomic deviations from normal as the first step in planning corrective osteotomy. Three-dimensional computed tomography (CT) reconstruction in planning reconstructi...

Successful bone sawing requires a high level of skill and experience, which could be gained by the use of Virtual Reality-based simulators. A key aspect of these medical simulators is realistic force feedback. The aim of this paper is to model the bone sawing process in order to develop a valid training simulator for the bilateral sagittal split osteotomy, the most often applied corrective surg...

The development of lateral tibial torsion in the paralysed lower limb is well documented, but its pathogenesis is poorly understood. This paper attempts to provide an explanation for its development when it is associated with a varus or equinovarus deformity of the hindfoot. Correction of the lateral tibial torsion by supramalleolar derotation tibial osteotomy and reorientation of the ankle mor...

Madelung's deformity results from a growth defect in the palmar and ulnar region of the distal radius. It presents as an excessively inclined radial joint surface, inducing "spontaneous progressive palmar subluxation of the wrist". The principle of reverse wedge osteotomy (RWO) consists in the reorientation of the radial joint surface by taking a circumferential bone wedge, the base of which is...

A corrective osteotomy for post-traumatic malalignment of the distal end of the radius was performed in twenty patients who were followed for an average of 3.6 years. The indications for correction were based on age, degree of deformity, limitation of function, pain, and appearance of the wrist. The procedure included an opening-wedge metaphyseal osteotomy combined with insertion of a graft and...

AIM The purpose of this study is to assess the symptoms caused by excessive femoral anteversion and the outcomes of femoral derotation osteotomy. METHODS We reviewed data on patients who underwent proximal femoral derotation osteotomy for symptomatic intoeing gait caused by femoral anteversion. Only symptomatic patients were considered for corrective derotation osteotomy. Degree of femoral an...

OBJECTIVES To describe the surgical treatment of pes varus in Dachshund dogs by medial opening wedge osteotomy of the distal tibia stabilized with a locking plate system and to retrospectively report the clinical and radiographic outcomes. MATERIALS AND METHODS Lameness in nine limbs of seven Dachshund dogs with pes varus deformity was treated with corrective osteotomy at or near the centre o...

On in vitro incubation of articular and epiphysial cartilage of the ulna of the domestic pig 70 to 80 per cent of [U-14C] glucose was metabolised to 14C-lactate, but cartilage of the epiphysial plate produced up to five times as much 14C-CO2 as articular cartilage, and the specific radioactivity of 14C(or 35S)-chondroitin 4(6)-sulphate isolated from epiphysial cartilage (following 35S-sulphate ...
