Treatment of recurrent patellar instability with a modification of the Roux-Goldthwait technique.

Recurrent instability of the patella may be a significant disability in the childhood and adolescent population. Numerous surgical procedures to address this instability have been described, with variable outcome. This has led to considerable confusion in the literature as to how to treat patellofemoral problems in children.

Arthroscopically assisted central physeal bar resection.

Thirty-seven central physeal bars were removed with an arthroscopically assisted technique. Thirty children (32 cases) have been followed to maturity or physeal closure. There were 19 boys and 11 girls, aged 4-14 years (mean, 9.

Treatment of ankle instability in children and adolescents with a modified Chrisman-Snook repair: a clinical and patient-based outcome study.

Ligamentous injuries to the lateral ankle complex, although rare in the child with open physes, increase with age and are seen with considerable frequency in late childhood and adolescence. In athletic, ligamentously lax individuals, recurrent sprains may lead to ligament attenuation and instability. When instability becomes chronic and interferes with everyday activity, reconstruction is indicated.

Animal models for spinal fusion.

Animal models for spinal fusion are essential for preclinical testing of new fusion methods and adjuncts. They allow for control of individual variables and quantification of outcome measures. Model characteristics are considered.

Arthroscopic treatment of septic arthritis in a patient with posterior stabilized total knee arthroplasty.

We report on a case of arthroscopic treatment of septic arthritis of the knee in a 73-year-old woman with a posterior stabilized knee endoprosthesis. Six months after arthroplasty of the right knee joint because of osteoarthritis, the patient experienced an erysipelas of the right lower leg after a cat bite. Although given intravenous antibiotic therapy, the patient developed septic arthritis of the right knee.

Thromboembolic complication after arthroscopic shoulder surgery.

Thromboembolic complications after arthroscopic shoulder surgery are very unusual and need thorough investigation of the possible origin. In this case of venous pulmonary thromboembolism after arthroscopy of the shoulder, neither a hint of coagulopathy nor an anatomic abnormality could be found that explains this complication. Therefore, irritation of the subclavian vein caused by compression by the motor-driven shaver is probably one cause for our thromboembolic complication.

Neuromuscular function in athletes following recovery from a recent acute low back injury.

Study Design: Observational case control design.

Objectives: To examine muscle response to sudden trunk loading in athletes with and without a recent history of acute low back injury (LBI).

Background: Impaired neuromuscular function is associated with chronic low back pain.
