Little League survey: the Houston study.

1. In a study of 595 Little League pitchers, approximately 17% had a history of elbow symptoms: only 1% had elbow symptoms which had ever excluded them from pitching. There was no correlation between the presence of symptoms and years of pitching experience. 2. Some limitation of active extension of the elbow was seen in 12% of the pitchers; however, there was no correlation between elbow flexion contractures and years of pitching experience, symptoms, or roentgenographic pathology. No normal child had an elbow flexion contracture greater than 15 degrees. 3. A slight valgus carrying angle is considered a normal anatomic variant in the dominant arm. There was no correlation between valgus carrying angle and years of pitching experience or symptoms or roentgenographic pathology. 4. No roentgenographic evidence of avascular necrosis of the capitellum, radial head, or both was seen in this population. 5. Roentgenographic findings such as bony hypertrophy, enlargement of the medial epicondyle, and secondary ossification centers are normal anatomic variants not related to symptoms. Undisplaced stress fractures of the medial epicondyle respond well to conservative treatment, with no functional residual.

An analysis of 100 symptomatic baseball players.

The management of baseball elbow injuries, both operative and nonoperative, was usually successful, permitting continued high-level athletic participation. Surgery was particularly effective in those cases with loose bodies. In the shoulder, symptoms occurred in the anterior and posterior regions. Each area presented difficulties in accurate diagnosis. The management of anterior symptoms was primarily nonoperative, surgery being reserved as a salvage procedure. In the posterior capsular syndrome, the source of pain is still unclear.

Proplast leader for use in cruciate ligament reconstruction.

A synthetic leader has been used in 18 cases of medial one-third patellar tendon substitution for the anterior cruciate ligament and in 10 cases of posterior cruciate substitution using the medial head of the gastrocnemius tendon. The device adds length and facilitates manipulation of the transplanted tissues. There have been no problems with biocompatibility and there have been no instances of staple loosening or disruption of the junction between the stabilizer and transplanted tissues. Early results with the anterior cruciate substitutions suggest thet anchoring the transfer in bony tunnels in both the tibia and femur does not allow sufficient flexibility to prevent stretching or disruption of the tendon transfer.

Acromioclavicular lesions in children.

This study reports on the followup of 25 children who were thought to have complete acromioclavicular joint dislocations. The patients were from 5 to 16 years old at the time of injury. Followup ranged between one and nine years. All were treated surgically. Various methods of stabilization were used, including transfixing the acromioclavicular joint with pins or a Bosworth screw and Mersilene (Ethicon, Somerville, NJ) taping of the clavicle to the coracoid. Good or excellent results, including return to full, asymptomatic activity and essentially normal clinical and roentgenographic appearance, were seen in over 90% of the cases. None of the children developed growth disturbances. Two of the 25 developed asymptomatic acromioclavicular joint arthritis, and both were cross-pinned. Children below the age of 13 years rarely sustain a complete acromioclavicular joint dislocation, but usually sustain a fracture of the distal clavicle with an intact acromioclavicular joint. Five (20%) of 25 patients below age 13 were erroneously diagnosed as having an acromioclavicular joint lesion. These children had only a fracture of the distal clavicle with rupture of the coracoclavicular ligament complex. Children of 13 years and older usually sustained complete dislocations of the acromioclavicular joint similar to adults. In children below age 13, conservative treatment should produce good or excellent results. Patients above age 13 all had adult-type acromioclavicular joint dislocations and were, accordingly, treated as adults.

A modification of the Bristow procedure for recurrent anterior shoulder dislocation and subluxation.

A modification of the Bristow procedure for recurrent anterior shoulder dislocation and subluxation is presented. This report includes 20 shoulders in 20 patients available for adequate followup operated on by senior author from April 1976 to August 1981. The average follow-up period was 42.5 months (3.5 years). The average age at the time of surgery was 24.7 years. No recurrences were noted in the follow-up period. Complications related to screw fixation with Woodruff screws occurred early in the series in three patients (15%), but did not result in instability. Range of motion measurements postoperatively emphasized quantitation of external rotation at 90 degrees of abduction in the operated as compared to the nonoperated shoulder. The average loss of external rotation was 10.3 degrees. Excluding one poor result, this equated to an average loss of only 7.4 degrees. Fourteen of 16 operated dominant arms (87.5%) returned to throwing and overhead motion sports postoperatively. A description of the operative procedure and postoperative rehabilitation course is included. This modification emphasizes accurate and firm repair of the Bankart lesion under excellent operative exposure allowing institution of early range of motion exercises.
