OBJECTIVE: To report repair and reconstruction of massively damaged wound under unusual condition. METHODS: One hundred and forty-seven patients with deep tissue defects were admitted from January 1993 to December 2000, among them, 96 cases suffered from electrical injury, 18 cases with hot press injury, 18 cases with deep burns as a result of CO poisoning or epileptic seizure, 6 cases caused by chemical producing necrosis and wound infection, 3 cases with radiation injuries, 2 cases with chemical burn, 2 cases with explosive injury, 2 cases with frostbite. One hundred and seventy five wounds in 147 patients were repaired by transfer of local flap, forearm conversal island skin flap, pectoralis major myocutaneous flap, delto-pectoral skin flap, latissimus dorsi skin flap, gastroecnemius myocutaneous flap, anterior and posterior tibial artery island skin flap, and so on. The wound defect ranged from 1 cm x 1 cm to 20 cm x 28 cm, and the flaps were 1.5 cm x 2.0 cm to 22 cm x 30 cm. The necrotic tendon was replaced with acellular allogenic tendon simultaneously in 7 cases. RESULTS: One hundred and sixty-nine flaps were survival with first intention, while necrosis of the tip of flap occurred in 6 cases. The transplantation of acellular allogenic tendon in all cases were survival. The function and configuration in 28 cases were satisfactory after 4 months to 8 years follow-up. CONCLUSION: Various types of flaps are choosen according to the position, defect range and degree of wound, which is an ideal method to restore the function and to improve patients’ living condition.
Objective To estimate the clinical curative effect of replacement of inverttype artificial total scapula and shoulder joint prosthesis and reserving arm with rehabilitation of function in the treatment of malignant tumor in shoulder. Methods From February 2001 and November 2004, five youth patients with primary malignant shoulder tumors were treated operatively by resection of neoplasmsthoroughly, replacement of inverttype artificial total shoulder blade and joint prosthesis, the functional reconstruction. Of them, there were 4 males and 1 female, aging from 19 to 26 years with an average of 23.6 years. Two cases were diagnosed as having osteosarcoma, one as having chondrosarcoma, and 2 as having Ewing sarcoma. After operation, the upper limbs was immobilized for 3 weeks. The rehabilitation training including passive exercise and initiative exercise. Results The average operative time was 425 min (380 to 530 min), and the blood loss ranged from 1 250 ml to1 900 ml(1 540 ml on average). The follow-up ranged from 7 to52 onths,with an average of 24.6 months. Postoperative complication included 1 case of pneumothorax, one case of shoulder incision skin part necrosis and 1 case of clavicle stump raising and pierce skin with shallow infection. No complication of postoperative incision deeply infection, nerve damage and prosthesis exposure or dislocation occurred. According to the scoring system of JOA(Japan orthopaedics association), the average score was 65 (60 to 72). The flexion and extension function of elbow joint recovered to normal. Conclusion The replacement of inverttype artificial total scapula and shoulder joint prosthesis is an efficacious method for the treatment of malignant tumor in shoulder. There are advantages of numerous adaption, wide range of motion and goodstability. It can not only reserve arm but also rehabilitate function.
From 1979 to 1994, reparative and recons tructive surgery were used to repair the war injuries of skins, bones, blood vessels and nerves of the limbs in 800 cases. A systematic clinical study was carried out. Many new operative methods were used and the results of treatment were good. Innovations and modifications were made in technique. In 120 cases of warin juries having soft tissues defects including skin and muscles, various tissue transplantations were used with the hope to accomplish onestaged repair of the defect and reconstruction of motor function of muscle. To those infections of bone and joint in war injuries, following early eradication of infected focus, transplantation of musculocutaneous flap or omental graft was immediately carried out with the aim to obtain primary healing of the wound. In the treatment of bone defects from war wounds with loss of skin and muscles, the vascularized skeletocutaneous graft was used. In the treatment of 150 cases of injury of peripheral nerve from forearms, the result of good to fair rated 68.8 percent for upper extremity and that for lower extremity, it was 62.2 percent. Following the early repair of 500 cases of injury of peripheral blood vessels, the patency rate of the blood vessel was 90 percent. The result following by pass vascular graft in the treatment of forearms injury of blood vessels even with very poor local condition was still very successful.
Objective To study the treatment method and effect of abduction and lateral rotation l imitation of the shoulder in obstetric brachial plexus palsy (OBPP). Methods From February 2005 to August 2008, 11 patients with abduction and lateral rotation l imitation of the shoulder in OBPP were treated with dissection of the origin of subscapular muscle,transfer of the tendons of latissimus dorsi and teres major muscle to the tendons of supraspinous and infraspinous muscles. Among them, there were 6 males and 5 females with a mean age of 6 years (1-15 years). The main cl inical manifestations showed adduction, internal rotation contracture deformity of shoulder, l imited active and passive external rotation and severely restricted active abduction of shoulder. The passive abduction was more than 90°. According to Gilbert grading, there were 7 cases of grade 1 and 4 cases of grade 2. Based on Mallet score systems, the scores were 5 points in 3 cases, 6 points in 3 cases, and 7 points in 5 cases. The muscle strength of deltoid, supraspinatus, infraspinatus, teres major muscle and latissimus dorsi all reached 3-4 grades. Results One patient developed postoperative hematoma, wound healed after symptomatic management. Other patients achieved incision heal ing by first intention. All patients were followed up for 12 to 37 months (17 months on average). The active abduction and external rotation of the shoulder joints recovered obviously. The Gilbert grading were grade 2 in 1 case, grade 3 in 1 case, and grade 4 in 9 cases; the Mallet scores were 10 points in 1 case, 11 points in 2 cases, 12 points in 4 cases, 13 points in 3 cases, and 14 points in 1 case; showing significant differences when compared with those before operation(P lt; 0.01). The muscle strength of deltoid, supraspinatus, infraspinatus, teres major muscle and latissimus dorsi increased to 4-5 grades. Conclusion The dissection of the origin of subscapular muscle, transfer of the tendons of latissimus dorsi and teres major muscle to the tendons of supraspinous and infraspinous muscles can resolve shoulder adduction, internal rotation contracture, and can enhance abduction, external rotation strength. It is an effective operation for abduction and lateral rotation l imitation of the shoulder in OBPP.
Objective To discuss the definition of complicated giant cell tumor of the bone and retrospectively analyze the treatment protocols and their therapeutic results so as to provide a clinical basis for reducing the postoperative recurrence of this kind of tumor. Methods From April 2001 to April 2005, 22patients (11 males and 11 females, aged 15-66 years) with complicated giant cell tumor of the bone were treated by the marginal or wide excision. The tumor was located in the distal femur in 10 patients, the proximal tibia in 5, theproximal femur in 2, the proximal humerus in 2, the hip bone in 2, and the distal radius in 1. The Campanicci′s grading system was used and the patients were grouped as follows: Grade Ⅱ in 4 patients, and Grade Ⅲ in 18. The functional results of the patients were assessed by the clinical examination. The reconstruction methods were used in the forms of osteoarticular allografting (14 patients) and total arthroplasty (8 patients). Results The analysis on the follow-up (6-48 months, averaged 23 months) of the 22 patients revealedthat the complicated factors were as follows: the tumor breaking through the cortex with an extraosseous mass; the tumor having pathologic fracture; the tumor representing more biologically-aggressive lesions; and the tumor having one or more local recurrences. Two patients (9%) had a local recurrence respectively 8 and 11 months after operation, but improved respectively by limb amputation and radiotherapy. Total arthroplasty achieved a better articular function than osteoarticular allografting. All the patients with osteoarticular allografts showed various degrees of the bone union of the allograft with the host bone. Conclusion The marginal or wide excision of this kind of complicated giant cell tumor of the bone combined withosteoarticular allograft or total arthroplasty can reduce the local recurrence of the tumor and achieve a certain degree of the articular motion function.
Objective To evaluate the results of thumb opposition function by transferring the extensor carpi ulnaris and the extensor poll icis brevis muscle tendons. Methods Between March 2006 and August 2009, 35 patients with dysfunction of thumb opposition were treated and the thumb opposition function was reconstruced by transferring the extensor carpi ulnaris and the extensor poll icis brevis muscle tendons. There were 25 males and 10 females with an average age of 33.5 years (range, 20-53 years); 20 had median nerve injury in the wrist and 15 had median nerve injury with ulnar nerve injury. The causes were sharp instrument injury in 24 cases, blunt injury in 9 cases, and hot crush injury in 2 cases. Six cases complicated by shaft fractures of radius and ulna. All the patients underwent an operation of nerve repair at 1 to 3 hours after injury (mean, 2 hours). The time from injury to reconstructing operation was 6-14 months (mean, 7.5 months). Two cases was able to abduct thumb sl ightly, the others had no functions of thumb abduct and thumb opposition. Results All the wounds gained the primary healing. The patients were followed up 12-18 months (mean, 14 months). The wrist joint angle and thumb dorsal extension were satisfactory. Thumb abduct and thumb opposition function returned to normal in 20 patients with simple median nerve injury; in 15 patients with median nerve injury and ulnar nerve injury, thumb abduct and thumb opposition function returned to normal in 15 and 13, respectively. According to ZHAO Shuqiang’s standard, the results of thumb opposition function were normal in all patients at 12 months after operation. Conclusion It is a convenient and efficient procedure to reconstruct thumb opposition function by transferring the extensor carpi ulnaris and the extensor poll icis brevis muscle tendons.
OBJECTIVE: To evaluate the results of limb function and the methods of bone and soft tissue reconstruction of patients treated with allografting. METHODS: From May 1992 to January 1999, 90 patients suffered from bone malignant tumor were treated with allografting in different methods of internal fixations. The average follow-up was 37.5 months. The limb postoperative function, complications related to different surgical methods were compared according to Enneking evaluation system. RESULTS: Skin necrosis, infection, non-union, fracture of allograft were the main complications which affect patients’ limb postoperative functions. Of the 90 fresh-frozen allografting procedures, the final results of operation showed that hip joints and knee joints were better than the shoulder joints. More than 80% of the patients treated with interlocked intramedullary nail and allograft-prosthesis combination led to an over-all result that was excellent and good. Interlocked intermedullary nail was of recommended method of internal fixation. Early exercises of operative limbs could promote function recovery. CONCLUSION: Using of interlocked intramedullary nail and allograft-prosthesis combination are of recommended operation method and can be applied with better results, and early exercises of operative limbs will lead to better functions.
OBJECTIVE: To evaluate the clinical application of primary transfer of pectoralis major to reconstruct the elbow flexion and shoulder abduction. METHODS: 12 cases of old injury of branchial plexus with dysfunction of both elbow and shoulder joints were received surgical operation to reconstruct the palsy joints by primary transfer of pectoralis major, shoulder abduction was reconstructed by clavicular head and elbow flexion by sternal head respectively. All cases were followed up for 5 to 18 months. RESULTS: The function of both joints recovered obviously, the total superior rate is 91.7%. CONCLUSION: Only if the palsy joints, shoulder or elbow, remained normal or almost normal passive motion, and the muscle power of pectoralis major over 4 degrees, the primary transfer of pectoralis major should be a simple, reliable and convenient technique to reconstruct the palsy joints.

Methods From May 2001 to November 2003, 8 cases of soft tissue defect of posterior of hand and forearm were repaired with thoracico abdominal flaps with hilum for primary stage. The tendon transplantation and allogeneic tendon function reconstruction of hand were performed for secondary stage. The range of the flap was 9 cm×15 cm to 12cm×38 cm. Allogeneic tendon amounted to 6.Results All the flaps survived. The flap countour was good. The results of allogeneic tendon transplantation were satisfactory and the function of hand was good. Conclusion Repairing complex soft tissue defect of posterior of hand and forearm and reconstructing hand function by use of thoracico abdominal flaps with hilum and transplantation of allogeneic tendon have the satisfactory clinical results.
Objective〓〖WTBZ〗To assess treating results of functional reconstruction of irrecoverable partial injury of brachial plexus and to improve the function ofinjured upper extremity. Methods Seventiy-nine cases with irrecoverable partial injury of brachial plexus were treated in transfer of muscle (tendon) or by fuctional anthrodesis (fixation of tendon) from January 1984 to June 2003. According to the evaluation criterion by American Shoulder and Elbow, Hand Association,all patients were followed up in motion of reconstructive joint and daily activities after operation for 1 year to 19 years. The effect of the operation was comprehensively scored and evaluated. Results Final results in 54 caseswere as follows: 30 patients with good results, 19 patients with fair results, and 5 with poor results. The results demonstrated some points as follow: ①if the shoulder was instable, athroedesis of shoulder would be a better choice;②the flexion of the elbow joint should be only reconstructed with the dynamic reconstructive methods. The reconstruction of flexion of elbow by transfer of pectoral major muscle was more effective than that by transfer of flexor carpi ulnaris muscle; ③the dynamic reconstruction of extension of digital and carpi was better than that of flexion of digital and opposition function of the thumb; ④the supination of the forearm was effectively reconstructed by transfer of flexorcarpi ulnaris muscle. Pronation teres muscle should be studied more in reconstruction of supination function of the forearm.
