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 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 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 investigate the feasibil ity, safety and operative techniques of percutaneous vertebroplasty (PVP) in treating osteolytic bone metastasis of cervical vertebra and reconstructing the function of cervical vertebra. Methods From March 2005 to December 2007, 10 patients with osteolytic bone metastatic carcinoma in single cervical vertebral body received PVP, including 5 males and 5 females aged 38-75 years (mean 54.5 years). Among them, 5 patients had primary lung tumor, 1 primary renal tumor, 1 primary breast tumor, 1 primary cervical tumor and 2 unknown primary lesion. The course of disease was 2-4 years. All the patients suffered from obviously cervical pain and l imitation of activity, including 4 cases of metastatic tumor of the C2 vertebral body, 2 of C3, 2 of C6 and 2 of C7. The general condition of patients was stable before operation, and no blood coagulation dysfunction, radiculalgia and spinal cord compression were detected. Lateral PVP was performed on 6 cases, approaching between the vertebral artery and the carotid sheath under CT guidance and anterolateral PVP was performed on the rest 4 cases, approaching between the trachea and the internal carotid artery under continuously X-ray fluoroscopy. The amount of bone cement injected was 3-4 mL, and the fill ing rate was 50%-100%. Results Without obvious bleeding or organ injury, the puncture was performed successfully on all the patients. Without symptom of spinal cord compression, patients suffered from pain during operation (1 case) and such compl ications noted by immediate CT or X-rays examination after operation as paravertebral epidural cement leakage (2 ases),transverse foramen cement leakage (1 case) and pinhole reflux (3 cases). The pain of patients was improved to various degree postoperatively, the visual analogue scales score was (5.9 ± 1.2) points before operation, which was changed to (2.6 ± 1.2) points at 1 hour after PVP and (1.6 ± 1.3) points at 1 week after PVP, indicating there was a significant difference between pre- and postoperation (P lt; 0.05). During the regular follow-up at 1 week, 3 and 12 months after PVP, all patients had no dislocation of cervical vertebra body, spinal cord compression and paralysis. Five patients died from multiple organ failure due to primary tumor progression, including 3 cases at 6 months after PVP and 2 at 12 months after PVP, and the rest 5 patients’ cervical pain were under control, with sound functional recovery. Conclusion PVP can rel ieve pain quickly and reinforce the stabil ity of the vertebral body, and has sl ight compl ications; the lateral approach is safe and effective.
Objective To evaluate the results of open arthrolysis by elevated the lateral and medial collateral l igament-musculature complex from the supracondylar ridge of the humerus in treatment of post-traumatic elbow stiffness. Methods From March 2003 to December 2007, 33 patients with post-traumatic elbow stiffness were treated with open arthrolysis by elevated the lateral and medial collateral l igament-musculature complex from the supracondylar ridge of the humerus. There were 23 males and 10 females, aged 17-70 years old (mean 41.8 years old). According to Morrey, 15 caseswere extremely serious (less than 30° extension-flexion arc) and 18 cases were serious (30-60° extension-flexion arc). The range of motion of the elbow stiffness was (32.5 ± 28.9)° and the Mayo score was 51.9±13.1 before operation. All initial fractures were healed according to cl inical examination and X-rays films. All patients present with a post-traumatic elbow stiffness and the average period from initial trauma to elbow arthrolysis was 16.9 months (2-72 months). Results Wound infection occurred in 1 patient and cured after dressing change and anti-infectious treatment. The wounds healed by first intension in 32 cases. No patient showed sign of elbow instabil ity and debil itating pain. All patients were followed up 6 months to 5 years (mean 3.3 years). At last follow up, the Mayo score was 82.3 ± 14.4 and the range of motion of elbow stiffness was (108.8 ± 36.0)°; showing significant differences when compared with preoperation (P lt; 0.05). According to Mayo evaluation, the results were excellent in 11 cases, good in 18 cases, fair in 2 cases, and poor in 2 cases, the excellent and good rate was 87.88%. Thirty-one patients achieve satisfactory results. Two patients were not satisfied with the result, but the satisfactory results were achieved by a second arthrol ysis. Conclusion Open elbow arthrolysis and postoperative rehabil itation for patients with elbow stiffness can improve joint function and ensure the stabil ity of elbows.

Frequent ovarian cryopreservation was procedure slow-freezing protocols and vitrification protocols. Some laboratory and animal models of ovarian function reconstruction have come to gratifying results. Conclusion Ovarian function reconstruction has a potential cl inical value and provides a promising future.
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.
To introduce the experience and comprehend of appl ication of many kinds of skin flaps in repair of heel skin and soft tissue defect. Methods From August 1993 to April 2007, 242 cases of skin and soft tissue defect on heel were treated. There were 157 males and 85 females aged 27-76 years. There were 35 cases of unstable scar, 46 cases ofchronic ulcer, 57 cases of squamous cell carcinoma, 72 cases of mal ignant melanoma and 32 cases of injury. The defect area ranged from 2 cm × 2 cm to 8 cm × 14 cm, wound was with low-grade infection in 51 cases. The course of disease was 1 hour to 5 years. The lateral calcaneal flaps (34 cases), the dorsum pedis flaps (15 cases), the medial plantar artery island flaps (108 cases), the sural neurovascular flaps (36 cases), the saphenous neurocutaneous vascular flaps (26 cases) and free (myocutaneous) skin flaps (23 cases) were used to repair heel wounded surface according to specific location of heel wounded surface, range of skin and soft tissue defect. The size of the (myocutaneous) skin flap was 3.0 cm × 2.5 cm to 15.0 cm × 9.0 cm. The donor area was directly sutured or covered with skin grafts. Results In 242 cases, 235 cases achieved heal ing by first intention, 5 cases had partial necrosis of flaps, 2 cases had mild infection. The donor area healed by first intention. A total of 217 patients were followed up for 1 month to 60 months. The color of flaps were normal and the texture of flaps were softer than that of normal heel tissue; the flaps were wearable, the shape of flaps were satisfactory. The patients can walk after 6 months of operation, andthe gait was normal. In 118 cancer patients, no local tumor recurrence occurred, and distant metastatic lesions were observe in 22 mal ignant melanoma patients. In 32 cases of mal ignant melanoma followed up 60 months, no distant metastatic lesions were found. Conclusion In base of following the primary disease treatment, heel function reconstruction and contour structural feature remodel ing, we adopted some kind of island or free (myocutaneous) skin flap can be used to repair heel wound. The ideal effect in heel function reconstruction and contour structural feature remodel ing were obtained.
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 investigate the value of computer-aided design (CAD) in defining the resection boundary, reconstructing the pelvis and hip in patients with pelvis tumors. Methods Between November 2006 and April 2009, 5 cases of pelvis tumors were treated surgically using CAD technology. There were 3 males and 2 females with an average age of 36.4 years (range, 24-62 years). The cause was osteosarcoma, giant cell tumor of bone, and angiosarcoma in 1 case, respectively,and chondrosarcoma in 2 cases. According to the Enneking system for staging benign and mal ignant musculoskeletal tumors, regions I, I + II, III, IV, and I + IV is in 1 case, respectively. According to the principle of reverse engineering, 5 patients with pelvis tumors were checked with lamellar CT/MRI scanning, whose two-dimensional data were obtained in disease area. The three-dimensional reconstruction of pelvic anatomical model, precise resection boundary of tumor, individual surgical template, individual prosthesis, and surgical simulation were precisely made by computer with CAD software. Based on the proposal of CAD, the bone tumor was resected accurately, and allograft il ium with internal fixation instrument or allogeneic il ium with personal ized prosthetic replacement were used to reconstruct the bone defect after tumor was resected. Results The operation was successfully performed in 5 cases. The average operation time was 7.9 hours, and the average blood loss was 3 125 mL. Hemorrhage and cerebrospinal fluid leakage occurred in 1 case, respectively, and were cured after debridement. Five patients were followed up from 24 to 50 months (mean, 34.5 months). All patients began non-weight bearing walk with double crutches at 4-6 weeks after operation, and began walk at 3-6 months after operation. Local recurrence developed in 2 patients at 18 months after operation, and resection and radiotherapy were performed. According to International Society of Limb Salvage criteria for curative effectiveness of bone tumor l imb salvage, the results were excellent in 2 and good in 3. Conclusion The individual surgical template, individual prosthesis, and surgical simulation by CAD ensure the precision and rel iabil ity of pelvis tumors resection. The CAD technology promotes pelvis tumor resection and the reconstruction of pelvis to individual treatment stage, and good curative effectiveness can be obtained.
