BACKGROUND The S-ROM-A prosthesis has been designed for the Asian proximal femur with a small deformed shape and narrow canal. In this study, the clinical and radiological results using the S-ROM-A prosthesis for Japanese patients with severe deformity due to dysplasia and excessive posterior pelvic tilt were examined. METHODS 94 hips were followed up for a mean of 55 months, with a mean age ...

BACKGROUND The treatment of complex diaphyseal malunions is challenging, requiring extensive preoperative planning and precise operative technique. We have developed a simpler method to treat some of these deformities. METHODS Ten patients with complex diaphyseal malunions (including four femoral and six tibial malunions) underwent a clamshell osteotomy. The indications for surgery included p...

PURPOSE Oblique proximal tibial osteotomy is a useful option for correcting deformity associated with Blount's disease (tibia vara). Safe, adequate correction depends on technical issues that have evolved since the original description of the procedure. METHODS Retrospective review of surgical experience. RESULTS The refinement of osteotomy plane orientation, based on the distal rather than...

Osteotomy procedures around the knee can alter the biomechanical axis of the knee, thereby shifting the load from one compartment to another. This can be used to unload an arthritic painful compartment or to decrease the weight experienced by a cartilage restoration procedure. Recent clinical and biomechanical studies have emphasized the importance of correcting the weight bearing axis in a car...

Coxa vara is an abnormality of the proximal femur with a decreased neck-shaft angle and resulting leg-length discrepancy, has been associated with conditions such as congenital coxa vara, traumatic injury, sepsis, rickets, vascular damage, or metabolic disorders; however its possible relationship with extracorporeal membrane oxygenation has been recently reported.A full term girl was born with ...

OBJECTIVE To assess movement of ulnar segments radiographically, following proximal and midshaft ulnar osteotomy or ostectomy after arthroscopic treatment for dogs diagnosed with medial coronoid disease. METHODS Fragmentation and cartilage wear were treated arthroscopically and the presence of incongruity confirmed. Osteotomies were performed at the mid-point or proximal third of the length o...

BACKGROUND The work presents the results of total hip arthroplasty in the treatment of arthrosis secondary to for developmental dysplasia with high hip dislocation or corollary to previous surgery of dysplastic high riding hips. In all patients the cup was placed in its anatomical position. In order to avoid excessive lengthening of the operated limb and the associated complications, the femora...

BACKGROUND Ganz surgical hip dislocation is useful in the management of severe hip diseases, providing an unobstructed view of the femoral head and acetabulum. We present our early experience with this approach in pediatric hip diseases. METHODS Twenty-three hips of 21 patients with pediatric hip diseases treated using the Ganz surgical hip dislocation approach were the subjects of this study...
