Reliability of the acetabular reconstruction technique using autogenous bone graft from resected femoral head in hip dysplasia: Influence of the change of hip joint center on clinical outcome.

Introduction: The previous studies have not reached on consensus as to the outcome of acetabular reconstruction with autogenous bone graft for dysplastic hips, especially in severe cases such as Crowe type IV. The current study aimed to determine the survivorship of the arthroplasty and the grafts as well as the change of hip joint center averagely 9.8 years (range, 5-19) after cementless total hip arthroplasty.

Experimental measurement of tympanic membrane response for finite element model validation of a human middle ear.

The middle ear consists of a tympanic membrane, ligaments, tendons, and three ossicles. An important function of the tympanic membrane is to deliver exterior sound stimulus to the ossicles and inner ear. In this study, the responses of the tympanic membrane in a human ear were measured and compared with those of a finite element model of the middle ear.

Penetration depth and size of the nonarthritic glenoid: implications for glenoid replacement.

Shoulder arthroplasty is technically demanding and relies heavily on precise surgical technique and preoperative planning. Proper glenoid component sizing plays a crucial role for successful shoulder arthroplasty. In this study, we measured the glenoid size together with penetration depth using three-dimensional computed tomography (3D-CT).

Resection arthroplasty for septic arthritis of the sternoclavicular joint.

Background: Treatment for septic arthritis of the sternoclavicular (SC) joint with concomitant osteomyelitis of the clavicle often requires joint resection rather than simple incision and drainage. We evaluated the effectiveness of resection arthroplasty for patients with septic arthritis of the SC joint.

Methods: We retrospectively reviewed 10 patients who underwent resection arthroplasty for SC joint septic arthritis between 1996 and 2008.
