  • EFFECTIVENESS COMPARISON BETWEEN TWO DIFFERENT METHODS OF ANTERIOR TRANSPOSITION OF THE ULNAR NERVE IN TREATMENT OF CUBITAL TUNNEL SYNDROME

    Objective To compare the effectiveness of anterior subcutaneous transposition and anterior submuscular transposition of the ulnar nerve in the treatment of cubital tunnel syndrome. Methods Between June 2006 and October 2008, 39 patients with cubital tunnel syndrome were treated separately by anterior subcutaneous transposition (anterior subcutaneous transposition group, n=20) and anterior submuscular transposition (anterior submuscular transposition group, n=19). There was no significant difference in gender, age, duration, and cl inical classification between 2 groups (P gt; 0.05). Results All incisions healed by first intention in 2 groups. In anterior submuscular transposition group, 17 patients (89.5%) had abruptly deteriorated symptoms after the symptom of ulnar nerve compression was abated, and 1 patient (5.3%) had cicatrix at elbow; in the anterior subcutaneous transposition group, 10 patients (50.0%) had disesthesia at cubital anterointernal skin after operation; and there was significant difference in the complication between 2 groups (χ2=9.632, P=0.002). The patients were followed up 24 to 36 months, 28 months on average. There was no significant difference in grip strength, pinch power of thumb-to-ring finger and thumb-to-little finger, or two-point discrimination of distal l ittle fingers between 2 groups (P gt; 0.05), but significant differences were found between before operation and after operation in 2 groups (P lt; 0.05). According to the Chinese Medical Society of Hand Surgery Trial upper part of the standard evaluation function assessment, the results were excellent in 5 cases, good in 12 cases, fair in 1 case, and poor in 2 cases in the anterior subcutaneous transposition group; the results were excellent in 6 cases, good in 10 cases, fair in 2 cases, and poor in 1 case in the anterior submuscular transposition group; and there was no significant difference between 2 groups (u=0.346, P=0.734). According to disabil ity of arm-shoulder-hand (DASH) questionnaires, the score was 22 ± 7 in anterior subcutaneous transposition group and was 19 ± 6 in anterior submuscular transposition group, showing no significant difference (t=1.434, P=0.161). Conclusion Both anterior subcutaneous transposition and anterior submuscular transposition have good effectiveness in treating cubital tunnel syndrome; and anterior submuscular transposition has less complication than that of submuscular transposition.

  • SURGICAL TREATMENT OF ANTERO-MEDIAL ROTATORY INSTABILITY OF KNEE JOINT CAUSED BY MOTORCYCLE

    Objective To discuss the effectiveness of operation technique for antero-medial rotatory instability (AMRI) of the knee joint caused by motorcycle. Methods Between June 2007 and December 2009, 32 cases of AMRI caused by motorcycle were treated. There were 28 males and 4 females with an average age of 35.5 years (range, 20-50 years). The interval between injury and surgery was 5-10 days (mean, 7 days). The anterior cruciate ligament (ACL) was injured at the attachment point of the condyles crest; the medial collateral ligament (MCL) was injured at central site in 19 cases, at medial condyles of femur in 10 cases, and at medial condyles of tibia in 3 cases, which were all closed injuries. The bone avulsion of condyles crest was fixed by steel wire and MCL was repaired. Results Red swelling and a little effusion occurred at the incision in 1 case, and the other incisions healed by first intention. Traumatic arthritis of the knee occured in 5 cases. Thirty-two cases were followed up 16-22 months (mean, 18.5 months). The X-ray examination showed that the fracture union time was 5-8 weeks (mean, 6 weeks) after operation. At last follow-up, the extension of knee joint was 0° and the flexion of the knee joint was 110-170° (mean, 155°). According to the synthetic evaluating standard of International Knee Documentation Committee, 24 cases were rated as A level, 6 cases as B, 1 case as C, and 1 case as D at last follow-up. Lysholm knee score was 85.93 ± 3.76 at last follow-up, which was significantly higher (t=53.785, P=0.000) than preoperative score 37.54 ± 3.43. Conclusion In patients with AMRI caused by motorcycle, steel wire is used to fix the bone avulsion of condyles crest and MCL should be repaired simultaneously as far as possible. And associating with the early postoperative functional exercise, the short-term effectiveness is satisfactory, but long-term effectiveness still need further follow-up observation.
