Extruded osteoarticular distal tibia: success at 18-month follow-up with reimplantation.

Extruded bone is a rare complication of open fractures associated with high energy. We describe a case of bony extrusion involving an osteoarticular segment of distal tibial treated with reimplantation and internal fixation with 18-month follow-up.

Autologous chondrocyte implantation of the ankle: a 2- to 5-year follow-up.

Background: Treatment of full-thickness talar cartilage defects that have failed previous surgery is problematic without a definitive solution.

Purpose: To report the first US prospective study of autologous chondrocyte implantation of the talus.

Study Design: Case series; Level of evidence, 4.

Periodically relieving ischial sitting load to decrease the risk of pressure ulcers.

Objective: To investigate the relieving effect on interface pressure of an alternate sitting protocol involving a sitting posture that reduces ischial support.

Design: Repeated measures in 2 protocols on 3 groups of subjects.

Setting: Laboratory.

Mini-open medial reefing and arthroscopic lateral release for the treatment of recurrent patellar dislocation: a medium-term follow-up.

Background: Although recurrent patellar dislocations are not uncommon, their pathophysiology and treatment are controversial.

Hypothesis: Stabilization of recurrent patellar dislocations can be successfully managed with a mini-open approach.

Study Design: Case series; Level of evidence, 4.

Biomechanical and histological evaluation of osteochondral transplantation in a rabbit model.

Background: Biomechanical and histological properties of osteochondral transplantation have not been extensively examined.

Hypothesis: Osteochondral grafts have properties similar to native articular cartilage.

Study Design: Controlled laboratory study.

The diagnosis and treatment of superior labrum, anterior and posterior (SLAP) lesions.

The advent of shoulder arthroscopy, as well as our improved understanding of shoulder anatomy and biomechanics, has led to the identification of previously undiagnosed lesions involving the superior labrum and biceps tendon anchor. Although the history and physical examination, as well as improved imaging modalities such as magnetic resonance arthrography, are extremely important in understanding the abnormalities, the definitive diagnosis of superior labrum, anterior and posterior lesions is best made through diagnostic arthroscopy. Treatment of these lesions is directed according to its type.
