Objective To investigate the method and the cl inical outcomes of reconstruction of the knee stability after resection of tumors of the proximal fibula. Methods The cl inical data were retrospectively analyzed, from 16 patients with tumors of the proximal fibula undergoing proximal fibular resections and reconstructions of the lateral collateral ligament and the tendon of the biceps femoris with anchors between January 2008 and December 2009 (test group). Five patients underwent proximal fibular resection but were not given reconstruction surgery at the same period as the control group. There was no significant difference in gender, ages, disease duration, and tumor site between 2 groups (P gt; 0.05). Lateral stress test was performed after operation; X-ray films were taken to measure the joint space. Musculoskeletal Tumor Society (MSTS) functional score system was used to evaluate the joint function. Results All incisions healed by first intention in 2 groups. Iatrogenic complete peroneal nerve function loss occurred in patients undergoing Malawer type II surgical resection. The patients in both groups were followed up 12 to 36 months, with an average of 30 months. One patient with osteosarcoma of the test group developed local recurrence, and died of lung and systemic metastases after 12 months; the other patients had no recurrence. At last follow-up, the results of knee lateral stress test were negative in the test group, and the joint space increased and was classified as grade A; the results of knee lateral stress test were positive in the control group, and the joint space was classified as grade D. The MSTS score was 97.5 ± 3.5 in the test group and 87.5 ± 3.5 in the control group, showing significant difference (t=2.85, P=0.01). Conclusion The reconstruction of the bony attachment of the lateral collateral ligament and the tendon of the biceps femoris with anchors after resection of the proximal fibula is a safe, rel iable, and simple technique to reconstruct knee stabil ity after resection of tumors of the proximal fibula.
Objective To summarize the therapeutic effectinevess of incorporating pedicled retrograde flap of forearm transplantation for reconstructing severe contracture of the first web space and wrist. Methods Between November 2005 and February 2010, 26 patients with severe contracture of the first web and wrist were treated. There were 18 males and 8 females with an average age of 27 years (range, 12-45 years). The locations were the right sides in 15 cases and the left sides in 11cases. The injury reason included hot water scald in 7 cases, explosion hurt in 5 cases, traffic accident in 3 cases, hot pressing in 5 cases, and flame burns in 6 cases. The duration of scar contracture ranged from 6 to 26 months with an average of 11 months. According to the evaluation standard by GU Yudong et al., all had severe contracture of the first web space, and concomitant injuries included adduction deformity thumb, l imitation of the thumb extension and opposition function, and carpometacarpal flexion joint deformity. After scar contracture was released, the defect size ranged from 5.8 cm × 4.5 cm to 11.3 cm × 7.2 cm, which were repaired by the incorporating pedicled retrograde flap of forearm of 6.5 cm × 5.0 cm to 12.5 cm × 8.0 cm at size. The donor sites were directly sutured or repaired with skin graft. Results Bl ister and partial necrosis occurred at the distal end of the flaps in 2 cases, which were cured after dressing change. The other flaps survived and wounds healed by first intention. Incisions at donor sites healed by first intention. Twenty-six patients were followed up 6 to 24 months (mean, 15 months). The patients had functional recovery in thumb adduction and opposition at different degrees. At 6 months after operation, according to the Swanson et al. AMA system for total thumb activity, the total thumb function was improved significantly, and according to Jensen et al. measurement, the width and angle of the first web space were significantly increased, all showing significant differences (P lt; 0.05). Conclusion Incorporating pedicled retrograde flap of forearm transplantation for repairing severe contracture of the first web space and wrist could augment the first web space and improve the wrist flexible function.
OBJECTIVE: To study the reconstructional method and effect of shoulder joint function in the older obstetrical palsy with medial rotation contracture deformity. METHODS: From April 1996 to July 1999, 7 patients of older obstetrical palsy were adopted in this study. Among them, there were 5 males and 2 females, aged from 13 to 21 years old. No previous operation history and the main deformity was medial rotation contracture of shoulder. During operation, these patients were treated with "Z"-shape elongation of the tendon of subscapular muscle, transfer of the tendons of latissimus dorsi and teres major muscle to the tendons of supraspinous and infraspinous muscles. RESULTS: Followed up for 6 to 44 months(averaged 19 months), the Gilbert grading and Mallet scoring were 1.57, 7.57 preoperatively versus 3.45, 10.86 postoperatively, the abduction and external rotation of the shoulder joints recovered obviously. CONCLUSION: It is an effective operation for the older obstetrical palsy with medial rotation contracture of shoulder.
Objective To retrospectively reviewed the operative therapy of the terrible triad of the elbow. Methods From October 2003 to September 2007, 10 cases of terrible triad were treated, with an elbow dislocation and an associated fracture of both the radial head and the coronoid process. There were 3 males and 7 females with the age of 18-66 years. The injury was caused by traffic accidents in 4 cases, fall ing from a height in 4 cases, and tumbl ing in 2 cases. The coronoid process fractures of the patients were 5 cases of type I, 3 cases of type II and 2 cases of type III according to Regan- Morrey classification. The radial head fractures of the patients were 1 case of type I, 6 cases of type II and 1 case of type IIIaccording to Mason classification, and their radial heads of the other 2 patiants were resected before they were in hospital. The general approach was to repair the damaged structures sequentially from deep to superficial, from coronoid to anterior capsule to radial head to lateral l igament complex to common extensor origin. And selected cases were repaired of the medial collateral l igaments and assisted mobile hinged external fixation to keep the forearm fixed in functional rotation position. The function of the elbows were evaluated with the criteria of the HSS2 score system. Results The other wounds healed by first intention except 1 case which had infection 7 days after operation and whose soft tissue defect in posterior elbow were repaired with the pedicle thoracoumbil ical flap. The patients were followed up 6 to 51 mouths (mean 24.9 mouths). The fracture heal ing time was 6 to 20 weeks (mean 9.6 weeks). Six mouths postoperatively, the mean flexion-extension arc of the elbow was 106.5° (85-130°), and the mean pronation-supination arc of the forearm was 138°( 100-160°) respectively. According to the criteria of the HSS2 score, the results were excellent in 4 cases, good in 4 cases, and fair in 2 cases. No compl ications such as stiffness and ulnohumeral arthrosis occurred. The radial nerve injury was found in 1 patient 1 day after operation who was treated with neurolysis, and the nerve function was recovered after 4-6 months. And heterotopic ossification occurred in 6 patients 6 months after operation and radiographic subluxation developed in 1 patient 36 months after operation, and conservative treatment weregiven. Conclusion The terrible triad of the elbow can lead to serious elbow instabil ity and should be treated with operationto restore the anatomic structures, to repair the articular capsule and the collateral l igament, using the adjuvant hinged external fixation and early exercise to avoid immobil ization and recover the articular function.
Objective To study the repair and function reconstruction of complex soft tissue defect of posterior of hand and forearm. 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 To evaluate the short-term results of reconstruction of stiff elbow under arthroscopy technique in patients with elbow osteoarthritis. Methods Between March 2006 and March 2009, 38 cases of elbow osteoarthritis with contracture were treated under arthroscopy technique. There were 26 males and 12 females with an average age of 47.8 years (range, 26-66 years). Unilateral side was affected in all cases, including 13 cases at the left side and 25 at the right side with 30 patients on the dominant side. The disease duration was more than 6 months. X-ray examination showed that 31 patients had free body, and 28 had osteophytosis. Seven patients had ulnar neuritis. The arthroscopy functional reconstruction was performed including synovectomy, free body removal, and osteocapsular arthroplasty. Results All incisions healed by first intention. All patients were followed up 6-10 months (mean, 8 months). Transient radial nerve injury occurred in 1 case, re-adhesion of elbow joint in 1 case, and heterotopic ossification of brachial ulnar joint in 1 case at 6 months after operation. In 1 patient compl icated by ulnar neuritis, the disorder of ulnar nerve was not improved, nervous symptoms disappeared after the re-operation of ulnar nerve relaxation after 2 months. The range of motion, Mayo Elbow Performance Score (MEPS), and visual analogue scale (VAS) for pain at 3 and 6 months had significant differences when compared with those before operation (P lt; 0.05), but had no significant difference between two time points after operation (P gt; 0.05). According to MEPS functional criteria, the results were classified as excellent in 20 cases, good in 15 cases, fair in 2 cases, and poor in 1 case at 6 months after operation, and the excellent and good rate was 92.1%. No new free body or osteophytosis occurred after operation by X-ray examination. Conclusion The arthroscopy is an effective technique to reconstruct the function of stiff elbow, which can obviously improve the range of motion and the function of elbow joint, and has good short-term results.
Objective To evaluate the cl inical outcomes of the wide resection and the functional reconstruction for treating mal ignant tumors of the proximal femur. Methods The cl inical data were analysed from 62 patients with mal ignant tumors of the proximal femur treated between January 1987 and December 2007. There were 29 males and 33 females with a median age of 35 years (range, 14-73 years). In 41 patients with primary mal ignant tumors having a disease course of 0.5-14.0 months, there were 16 cases of osteosarcoma, 7 cases of fibrosaroma, 6 cases of chondrosarcoma, 6 cases of mal ignant fibrous histiocytoma, 4 cases of mesenchymal sarcoma,1 case of Ewing sarcoma, and 1 case of angiosarcoma, including 3 cases of type IB, 2 cases of type IIA, 35 cases of type IIB, and 1 case of type III according to Enneking stage. In 21 patients with metastatic tumors, 16 had a mal ignant tumor history; the disease course was 0.1-28.0 months (3.4 months on average). Radical resection was performed in 9 cases, extensive resection in 39 cases, and marginal resection in 14 cases. After resection, 39 cases underwent reconstruction with prostheses (prostheses group) and 14 cases underwent reconstruction with allograft-prosthetic composites (APC, APC group). Results All incision healed by first intention. Twenty-six cases died of tumor metastasis,their postoperative survive time was 16-56 months (28 months on average). The average follow-up time was 64 months (range, 28-221 months) in 36 survival patients. The local recurrence rate of primary mal ignant tumors was 4.88% (2/41). In prostheses group, dislocation of femoral head occurred in 2 cases, fracture of prosthetic stem in 1 case, hip pain in 3 cases, acetabular wear in 3 cases, and stem loosening in 5 cases. In APC group, nonunion of APC occurred in 3 cases and acetabular wear in 1 case. At last follow-up, the average Musculoskeletal Tumor Society (MSTS) functional scores were 77.69% ± 6.50% in prostheses groupand 85.71% ± 7.45% in APC group, showing significant difference (P lt; 0.001). Conclusion When the wide resection isperformed for mal ignant tumors of the proximal femur, better local control could be achieved. Compared with econstruction of the prosthesis, the APC reconstruction can provide better function.
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 investigate a clinical method in repairing destructive hand injury and reconstructing hand function in early stage. METHODS: From January 1990 to June 1999, composite tissue transplantation was used to repair destructive hand damage and reconstruct hand function with vascular anastomosis in emergency (33 cases) or subemergency (126 cases). For the radial damage, combined flaps with toes was used to treat cicatricial contracture of thumb-web space. Opposing function of thumb was reconstructed by combined transplantation of short extensor muscle of great toe, short extensor muscle of toes or short abductor muscle of great toe in the same time of freeing the second toe. For no or deficient anastomosing vessels in donor site, "Y"--shaped reversal vein, anterograde bridging, or branches bridging of host vessels were applied. RESULTS: All of tissue transplantation were survived, including combined tissue transplantation in 51 cases, composite tissue transplantation in 4 cases, tissue transplantation after replantation of severed wrist and finger in 4 cases, there were no infection or necrosis in all cases, and hand function recovered well. CONCLUSION: It is an ideal procedure to repair destructive hand injury and reconstruct hand function by combined or composite tissue transplantation with vascular anastomosis in emergency or subemergency.
