In order to solve the difficult problems of repair and reconstruction for severe deep burns with compound tissue defects of upper limb, 26 cases were treated with transplantation of compound tissue flap, vascularized by anastomosis of blood vessel or by vascular pedicle. Several kinds of reparative and reconstructive procedure could be performed simultaneously. Not only the tissue defect was repaired, but also the upper limb function was reconstructed in one stage operation. Owing to the presence of abundant vascular supply from the vascularized compound tissue and primarily closing the wounds, the anti-infection potency was high, then it was suitable for such conditions as fresh severe deep burn with infection and compound tissue defects. As a result, this technique provided the best chance to save upper limb from amputation. The duration required for treatment could be markedly shortened. All the cases successed. The long-term functional recovery was satisfactory. This method provided the possibility to solve effectively the difficult problem dealing with the severe deep burns with compound tissue defects of upper limb.
OBJECTIVE: Both primary and metastatic tumor of spine can influence spinal stability, spinal cord and nerves. The principles of dealing spinal tumor are resection of tumor decompression on spinal cord and reconstruction of spinal stability. METHODS: Since Aug. 1993 to Oct. 1996, 15 cases with spinal tumor were treated, including 4 primary spinal tumor and 11 metastatic tumor. Tumor foci were mainly in thoracic and lumbar spine. Graded by Frankel classification of spinal injuries, there were 1 case of grade A, 1 of grade B, 3 of grade C, 5 of grade D and 5 of grade E. Tumors of upper lumbar spine and thoracic spine were resected through anterior approach. Posterior approach also was adopted once posterior column was affected. Tumors of lower lumbar spine were resected by two-staged operation: firstly, operation through posterior approach to reconstruct spinal stability: secondly, operation through anterior approach. After resection of tumor, the spines were fixed by Kaneda instrument, Steffee plate or Kirschner pins. To fuse the spine, bone grafting was used in benign tumor and bone cement used in malignant tumor. RESULTS: Except one patient died from arrest of bone marrow, the others were followed up for 3 to 20 months. Postoperatively, 11 patients could sit up on one foot with the help of body supporter, and 9 patients could walk in two weeks under careful monitoring. There was no exacerbation of symptom and failure of fixation. The function of spinal cord was improved: 1 case from grade B to grade E, 1 from A to C, 2 from C to E and 4 from D to E. CONCLUSION: The spine can be reconstructed for weight bearing early by internal fixation. The symptom can be relieved and the nervous function can be improved by resection of tumor and decompression.
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.
Twelve cases (13 hips) of congenital dislocation of hip (CDH)in a group above the age of six were treated by Chiari pelvic osteotomy from Jan. 1991 to Dec. 1992. The results following operative treatment rated as good in 85 percents according to the clinical and radiologic examinations. The indications, and the results with the operation as the functional reconstuction of the hip concerned were discussed.
ObjectiveTo explore the effectiveness of one-stage metacarpal osteotomy, thumb opponensplasty and polygonal flap reconstruction in the treatment of congenital spade hand deformity. MethodsEight cases of congenital spade hand were treated between January 2013 and March 2017. There were 5 males and 3 females, with an average age of 17.5 months (range, 13-35 months). The clinical manifestations of all the children were congenital spade hand and the affected hand was shorter than the healthy side. The contralateral hand was normal and there was no chest, skull, or facial deformity. The operation was performed with metacarpal osteotomy and thumb opponensplasty, and through the dorsal metacarpal rectangular flap to reconstruct the first web and through rotation of polygonal skin flap to reconstruct thumb web and lateral fold of thumb index nail. The dorsal ulnar and proximal radial segment of thumb were repaired by skin grafting. A vernier caliper was used to measure the first web space and the thumb function was evaluated by modified Tada score. ResultsThe reconstruction of palmar function and the formation of first web were completed in one stage in 8 children. Skin grafting on the dorsal ulnar side of thumb and radial side of index finger survived after operation. All the children were followed up 13-29 months, with an average of 16.1 months. There was no infection, skin flap necrosis, lateral deviation of thumb, scar contracture, or other complications. At last follow-up, there was no significant difference in skin color between the healthy side and the first web of the affected hand. The opening distance of first web space was 3.5-5.0 cm, with an average of 4.2 cm. According to the modified Tada scoring system, the results were excellent in 7 cases and good in 1 case, with an excellent and good rate of 100%. The thumb could grasp and pinch actively, and the palm opposition function was good. ConclusionOne-stage thumb opponensplasty combined with polygonal flap for reconstruction of congenital spade hand deformity can improve hand function very well. The reasonable designing of skin flap can effectively cover important areas, and the operation is safe and reliable.
ObjectiveTo investigate the effectiveness of modified extensor indicis proprius (EIP) tendon transfer for reconstruction of spontaneously ruptured extensor pollicis longus (EPL) tendon by comparing with the traditional EIP tendon transfer. MethodsBetween January 2009 and December 2011, 11 cases of spontaneously ruptured EPL tendon were treated by modified EIP tendon transfer to reconstruct extension function (modified group). On the base of traditional procedure, the proximal end of EPL tendon was sutured with EIP tendon and the distal end of EIP tendon was crossed round extensor pollicis brevis (EPB) tendon and sutured back with EPL tendon. A specific EI-EPL evaluation method (SEEM) was used to measure the EPL tendon function after transfer. The result was compared with that of the other 18 cases undergoing traditional operation (traditional group). There was no significant difference in gender, age, disease duration, and injury causes between 2 groups (P gt; 0.05). ResultsAll incisions healed by first intention. In traditional group, 5 cases were out of follow-up, and the other 24 cases were followed up 1 year and 6 months on average (range, 8 months-2 years and 6 months). At the last follow-up, according to the evaluation of SEEM, the thumb elevation and flexion deficits of modified group were significantly less than those of traditional group (P lt; 0.05). The independent elevation deficit of the index finger of modified group was similar to that of traditional group (P gt; 0.05). The effectiveness was excellent in 9 cases and good in 2 cases with an excellent and good rate of 100% in modified group, and was excellent in 5 cases, good in 6 cases, and fair in 2 cases with an excellent and good rate of 84.6%. The effectiveness of modified group was significantly better than that of traditional group (χ2=0.03, P=0.03). ConclusionReconstruction of EPL tendon function by modified EIP tendon transfer is effective and easy. It can increase strength of the transferred tendon and obtain satisfactory results, but the long-term effectiveness needs further follow-up.
ObjectiveTo review the research progress of the tissue engineering technique in the esophageal defect repair and reconstruction. MethodsThe recently published clinical and experimental literature at home and abroad on the scaffold materials and the seeding cells used in the tissue engineered esophageal reconstruction was consulted and summarized. ResultsA large number of basic researches and clinical applications show that the effect of the tissue engineered esophagus is close to the autologous structure and function of the esophagus and it could be used for the repair of the esophageal defect. However, those techniques have a long distance from the clinical application and need an acknowledged rule of technology. ConclusionTissue engineering technique could provide an innovative theory for the esophageal defect reconstruction, but its clinical application need further research.
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.
