Prediction of angular deformity and leg-length discrepancy after anterior cruciate ligament reconstruction in skeletally immature patients.

Injuries to the anterior cruciate ligament (ACL) in young children and adolescents are becoming more common as more youngsters participate in organized sports. The dilemma for the orthopaedic surgeon is that untreated ACL ruptures may result in meniscal damage and joint degeneration, whereas surgical treatment may result in physeal arrest, with shortening and angular deformity. To help determine the appropriate timing for ACL repair in skeletally immature patients, graphs have been developed to predict the amount of shortening and angular deformity to expect after repair.

Subtrochanteric fracture after fixation of slipped capital femoral epiphysis: a complication of unused drill holes.

Subtrochanteric fracture of the femur has been infrequently reported after in situ fixation of slipped capital femoral epiphysis, and this occurred in only 1.4% of our patients over a 10-year period. As this technique is used more frequently, however, the incidence of this complication is likely to rise. All four subtrochanteric fractures occurred through unused drill holes, and avoiding extraneous screw holes seems to be the best way to prevent postoperative subtrochanteric fracture. Once subtrochanteric fracture occurs, immediate open reduction and internal fixation with a compression hip screw device is the recommended treatment.

Recurrent voluntary anterior dislocation of the hip: case report and review of the literature.

Recurrent dislocation of the hip is uncommon in children, and anterior dislocation, as in the case reported, is extremely rare. Terminology is often confusing, with "recurrent," "voluntary," and "habitual" dislocations described. The causative pathology of the dislocation must be determined before appropriate treatment can be selected; computed tomography can be helpful in making this decision.

Long-term follow-up of patients with avascular necrosis after treatment of slipped capital femoral epiphysis.

A retrospective review of 264 patients treated for slipped capital femoral epiphysis (SCFE) identified 36 who developed avascular necrosis (AVN). Twenty-two patients (24 hips) were evaluated at an average follow-up of 31 years. Nine have undergone reconstructive surgery: four during adolescence and five during adulthood. The remaining 13 patients (15 hips) have had no further operations, but all show degenerative changes on current roentgenograms. The natural history appears to be that of gradual degenerative changes for which reconstructive surgery most often can be delayed until adulthood.
