METHODS: From August 1986 to July 2000, 224 patients with brachial plexus avulsion injuries were treated with contralateral C7 transfer in our department. Thirty-two patients were followed up for over 2 years for evaluation of the following items: 1 influence on healthy limb function; 2 sensory and motor recovery of the recipient nerves in the affected limb; and 3 coordination between the healthy and affected limbs. RESULTS: There was no impairment of healthy limb function. Functional recovery of the recipient area reached > or =M3 in 8 patients (8/10, 80%) after musculocutaneous nerve neurotization, > or =M3 in 4 patients (4/6, 66%) after radial nerve neurotization, > or = M3 in 7 patients (7/14, 50%) and > or = M3 in 12 patients (85.7%) after median nerve neurotization, and > or = M3 in 1 patients (1/2, 50%) after thoracodorsal nerve neurotization. Synchronic contraction of the affected limb with the healthy limb occurred within 2-3 years in 12 patients, within 5 years in 13 patients, and over 5 years in 7 patients. CONCLUSION: Contralateral C7 transfer is an ideal procedure for the treatment of brachial plexus root avulsion injury. Selection of the whole root or the posterior division as neurotizer and a staged operation are the major factors influencing treatment outcome.展开更多

In the fresh injury group 4 cases failed in close reduction due to "buttonholing" through the medial jo int,among them 3 cases underwent repair of the damaged ligaments. In the old in jury group 2 cases underwent ACL and MCL repair only in acute stage,but re-dis located. Of the rest 2 cases 1 was associated with peroneal nerve injury and the other was not treated in acute stage. One case was associated with comminuted f racture of the tibial condyle and popliteal artery injury. Open reduction was pe rformed in 3 cases. One case was fixed with 2-crossed pin and another was fixe d with one pin through the tibial and femoral condyle and second pin with olecra nization fixation. Plaster immobilization for 6-8 weeks respectively was requir ed. In the old injury group in 1 case ACL and PCL repair (Augustine method) and posterolateral structure were performed and olecranization fixation and plaster immobilization for 6 weeks was needed. Arthrodesis of the knee was done for the patient with comminuted fracture of the tibial condyle and popliteal artery inj ury. Results: All the cases were followed up for 1-23 years (averag e 6 years). Knee stability in 4 cases with repair of the ligaments was improved,although PDT showed (+) with different degrees. The results of the patients tre ated with ligamentous reconstruction were much better than those of the patients without any repair. Conclusions: Well understanding of the traumatic pathological c haracteristics,repair of the damaged ligaments,augmentation of olecranization fixation and postoperative immobilization for 6 weeks are the key points of succ essful treatment.展开更多
