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.

A chronicle of injuries of an American intercollegiate football team.

Many studies concerning the injuries occurring in high school and intercollegiate football have been reported, including those emphasizing the number and type of injuries, geographic distribution of injuries, and the rate of injury compared to position, conditioning, officiating, equipment, and type of playing surface. This report focuses on the individual player involved in a sports program for four or five years and emphasizes the statistical probability of that individual sustaining an injury during his playing career. Conclusions, drawn from statistics compiled at Memphis State University from 1975 through 1979, involved 265 athletes. These 265 athletes sustained 283 injuries during this period. Of these 283 injuries, 69% were mild, 20% were moderate, and 11% were severe. The knee was most often involved and suffered the most severe injuries. Ankle injuries accounted for the second highest incidence of injury, but these were primarily mild or moderate injuries. The defensive line, especially the defensive ends, received the greatest percentage of injuries. The probability of injury for the individual player was found to be 106.7% for a five-year participant, 99.1% for a four-year participant, and 46.6% for a one-year participant.

Percutaneous epiphysiodesis: experimental study and preliminary clinical results.

An experimental study was conducted to determine the feasibility of using percutaneous drilling and pneumatic burring under image intensification to effect premature closure of the distal femoral epiphyseal plate in immature New Zealand white rabbits. Serial roentgenograms were made before the animals were killed at 6 or 10 weeks to document leg length inequality as compared with the contralateral leg following the procedure. Microscopic examination of nonoperated and operated epiphyseal plate revealed complete arrest of the operated epiphysis with bone fusion at the epiphyseal plate in eight of the nine rabbits. Since this animal study, 13 children have undergone percutaneous epiphysiodesis. Roentgenographically, all the growth plates appeared fused following the procedure. However, complete growth arrest cannot be substantiated until skeletal maturity. This is a preliminary report of a procedure that needs further documentation.

Fractures of the patella in children and adolescents.

Patellar fractures are rare in children and usually result from high-energy trauma. Treatment guidelines generally are the same as for patellar fractures in adults. Between 1942 and 1987, 66 children with patellar fractures were treated. Exclusion of those with < 2-year follow-up, osteochondral fractures, or incomplete records left 24 patients for long-term follow-up. Overall results were good in 13, fair in eight, and poor in three. Children with fractures of the ipsilateral femur and/or tibia and those with comminuted, displaced fractures had the poorest results.

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.

Fractures of the olecranon in children: long-term follow-up.

Olecranon fractures are relatively uncommon in children, and most are nondisplaced or minimally displaced fractures that can be treated by closed methods. During a 30-year period, 44 olecranon fractures were treated. Of 41 fractures with adequate follow-up, 37 (90%) had satisfactory results. Of 30 undisplaced or minimally displaced (< 5 mm) fractures, 28 (93%) had satisfactory results. Seven of 9 (78%) displaced fractures had satisfactory results. The most common cause of unsatisfactory results was loss of motion, although this usually did not prevent good function.
