Distal femoral shortening in total hip arthroplasty for complex primary hip reconstruction. A new surgical technique.

Successful total hip arthroplasty (THA) in congenital dislocated hips demands anatomical reduction in the normal center of rotation without overstretching the sciatic nerve and without excessive compression or abnormal forces across the joint. Proximal femoral and subtrochanteric shortening osteotomy has been described for THA for the treatment of dislocated hips. However, these osteotomies are demanding, associated with deformation of femoral canal and nonunion, and may increase the femoral stem stress.

Radiographic total disc replacement angle measurement accuracy using the Oxford Cobbometer: precision and bias.

Total disc replacement (TDR) clinical success has been reported to be related to the residual motion of the operated level. Thus, accurate measurement of TDR range of motion (ROM) is of utmost importance. One commonly used tool in measuring ROM is the Oxford Cobbometer.

Custom-design implants for severe distorted proximal anatomy of the femur in young adults followed for 4-8 years.

Background: Treatment of hips with abnormal anatomy is challenging, and requires demanding surgical technique. We report the preoperative planning and the functional outcome of 38 patients with severe distorted anatomy who were treated with custom implants.

Patients And Methods: 38 consecutive patients (48 hips) were selected for customized femoral implants.

Cementless modular centroid reconstruction cup in young adults with congenital dysplasia of the hip.

The anatomic abnormalities associated with the dysplastic acetabulum make total hip arthroplasty a very complex and challenging procedure. Various techniques have been reported for the reconstruction of the dysplastic acetabulum. This prospective study examined the clinical results and technical challenges associated with acetabular reconstruction using a cementless modular centroid reconstruction cup in 62 dysplastic hips.

Posterolateral lumbar spine fusion using a novel demineralized bone matrix: a controlled case pilot study.

Introduction: Intertransverse posterolateral fusion along with instrumentation is a common technique used for spinal fusion. Iliac crest bone graft (ICBG) offers good fusion success rates with a low risk for disease transmission but is, however, linked with certain morbidity. In an effort to eliminate or reduce the amount of iliac graft needed, bone substitutes including demineralized bone matrix (DBM) have been developed.

Impact of iliac crest bone graft harvesting on fusion rates and postoperative pain during instrumented posterolateral lumbar fusion.

This study aims to evaluate the influence of bone harvesting on postoperative pain and fusion rates. Group 1 patients received iliac crest bone graft (ICBG) either alone or augmented with local bone. Group 2 received only local bone.

Long-term results of various therapy concepts in severe pilon fractures.

Introduction: Intra-articular fractures of the tibia plafond are among the most challenging of orthopaedic problems. This is a retrospective case-control study of surgically treated pilon fractures which was undertaken to compare the internal fixation with the two external fixation methods.

Methods: This is a case-control study of 55 patients with 55 pilon fractures.
