OBJECTIVE The correction of ectropion of lower lid and severe infra-orbital soft tissue depression is very difficult. Former methods included simple skin graft, tubed graft, transfer of local skin flap and so on. These methods had some disadvantages, such as not enough tissue to fill the depression, too much damage done to the donor area and operation in stages required. METHODS After investigation on the anatomy of temporal region, designed the following method. Combined transfer of the galea aponeurotica and temporal fascia was used to repair severe infra-orbital soft tissue depression and ectropion of lower lid in 6 cases. RESULTS It was discovered that the combined transfer of the galea aponeurotica and temporal fascia was rich in blood circulation because they received blood supply from parietal branch of superficial temporal artery and could be transferred to a distance as far as 15-18 cm. The skin graft used to cover the fascia usually resulted in good survival. This technique was used in 6 cases with good success. CONCLUSION This method had some merits such as the tissue flap had good blood supply, little damage done to the donor area, good correction of the severe depression, good appearance following correction, operation done under local anesthesia and completed in one-stage operation.
First metatarsophalangeal joint arthrodesis, as a corrective measure for severe hallux valgus deformity, has a long history and remains in use today. Indications for the first metatarsophalangeal joint arthrodesis include severe hallux valgus deformity, recurrent hallux valgus, hallux deformity in rheumatoid arthritis, severe hallux rigidus, joint infection, primary or secondary osteoarthritis, hallux valgus deformity due to neuromuscular disorders, and severe gouty arthritis. Innovative research continues to emerge in biomechanics and materials science related to the first metatarsophalangeal joint arthrodesis. Surgical fixation options are diverse and evolving, encompassing traditional screws and plates alongside novel intramedullary fixation systems and shape-memory alloy implants. Biomechanical studies, gait analysis research, and clinical trials consistently demonstrate minimal postoperative impact on gait and no significant impairment of functional mobility. When performed with proper technique, complications are rare. The first metatarsophalangeal joint arthrodesis is an effective and reliable method for treating severe hallux valgus deformity.
Objective To assess the effect of medial distal femoral osteotomy combined with interlocking nailing on the treatment of knee osteoarthritis with valgus deformity. Methods From May 1996 toAugust 2000, 16 patients with knee osteoarthritis accompanied by valgus deformity were treated by medial wedged distal femoral osteotomy combined with interlocking nailing. Full-length radiographs were taken before operation and 8 weeks and 2 years after operation. The parameters, including the femorotibial angle, the tibial angle, the femoral angle, the femoral condyletibial plateau angle, and the lateral joint space, were measured by these radiographs. The function of knee was evaluated by the 100 point rating scale standard of knee. Results The mean postoperative score was significantly improved from 50.4±15.9 points to 78.5±12.9 points 2 years after the surgery. The lateraljoint space was increased from 2.1±1.8 mm to 4.7±1.7 mm and the femoral condyletibial angle decreased from 5.6±2.9° to 1.6±3.4°. There were complications in 2 cases: 1 case of delayed union and 1 case of superficial wound infection. Conclusion Medial distal femoral osteotomy combined with interlocking nailing proves to be an effective approach to treat knee osteoarthritis with valgus deformity.
Objective To compare the outcomes of low/ultra-low anterior rectal resection and valgus resection in elder patients with rectal or anal cancer. Methods The clinical data of 184 patients with rectal or anal cancer， who were treated with extreme sphincter preserving surgery in West China Hospital from January 2009 to December 2011， were collected and analyzed retrospectively. The intraoperative and postoperative indexes between low/ultra-low anterior rectal resection group and valgus resection group were compared. Results ①There were no significant differences in the age，body mass index， gender， diameter of tumor， TNM stage， degree of differentiation， histological type， gross type， and complications before operation， such as hypertension， chronic obstructive pulmonary disease， cardiovascular diseases， diabetes， renal disease， and hypoproteinemia in two groups （P＞0.05）. ②Compared with the low/ultra-low anterior rectal resection group， the distance from the anal verge to the tumor was shorter （P＜0.05） and the distance of distal resec-tion margin of tumor was longer （P＜0.05） in the valgus resection group. ③There were no significant differences in the operation time， blood loss， ASA grade， and the postoperative complications in two groups （P＞0.05）. ④There were no significant differences in the duration of pulling out nasogastric tube， urinary catheter， and drainage tube， the duration of first passing flatus， first defecation， first oral intake， and first ambulation， and hospitalization cost （P＞0.05）. But the postoperative hospital stay and total hospital stay in the valgus resection group were significantly longer than those in the low/ultra-low anterior rectal resection group （P＜0.05）. ⑤All the patients were followed-up for 6-24 months （average 13 months）. During the following-up， only 1 case suffered local tumor recurrence in the valgus resection group. One case suffered distant metastases in the ultra-low anterior rectal resection and valgus resection group， respectively. Eight cases （4.35%） died， of which 4 cases （4.04%） in the low/ultra-low anterior rectal group and 4 cases （4.71%） in the valgus resection group. All the patients were in functional recovery of anal control after operation. Conclusions As the extreme sphincter preserving surgery for elder patients with rectal or anal cancer， the low or ultra-low anterior rectal resection and valgus resection could both be used for elder patients with extreme-low rectal or anal cancer. However， valgus resection results in longer distal surgical margin than that low/ultra-low anterior rectal resection， and it is suitable for the patients with shorter distances from the anal verge to the tumor.
ObjectiveTo investigate the effectiveness of open reduction and internal fixation with locking anatomical plate for treating valgus impacted proximal humerus fracture. MethodsA retrospective analysis was made on the clinical data of 38 patients with valgus impacted proximal humerus fracture who underwent open reduction and internal fixation with locking anatomical plate between January 2009 and January 2014. There were 25 males and 13 females, aged from 47 to 63 years (mean, 52.3 years); the left and the right sides were involved in 18 and 20 cases, respectively. The causes of fracture included high falling injury in 10 cases, traffic accident injury in 15 cases, and falling injury in 13 cases. The time between injury and operation was 5-10 days (mean, 7.5 days). The collodiaphyseal angle was 160-200° (mean, 176°) on X-ray films. ResultsAll incisions healed by first intention, and there was no early complication related to operation. All these patients were followed up 12-30 months (mean, 18 months). X-ray film showed that clinical healing time of fracture was 10-16 weeks after operation (mean, 12 weeks); at 12 months after operation, the collodiaphyseal angle recovered to 120-145° (mean, 135°). During follow-up, no loss of fracture reduction and no loosening of internal fixation were observed. At 10-12 months, osteonecrosis of the humeral head occurred in 3 cases (7.9%), including 2 cases of Cruess stageⅢand 1 case of Cruess stageⅣ. At last follow-up, the Constant shoulder joint scores were 56-95 (mean, 82.6); the results were excellent in 10 cases, good in 15 cases, fair in 9 cases, and poor in 4 cases, with an excellent and good rate of 66%. Visual analogue scale (VAS) scores were 0-6 (mean, 0.9). ConclusionIt can achieve a comparatively satisfactory clinical result to use open reduction and internal fixation with locking anatomical plate for treating valgus impacted proximal humerus fracture.

Using the axialflap method only 1 in 10 cases can not control the urinationwell, the others achive well the requcirement of functional bladder. The longest follow-up pcriod has lasted for more than 2 years. and the renal and bladder function ars completely normal. the axial flaps of the present method included skin flap, facial and vascular pedicles of 8 types. The application of the flaps has developed a new serjies of procedures that ars suitable for the treatmen of a varicty of extrophy deformities.
Objective To evaluate the primary cl inical effectiveness of Austin metatarsal osteotomy combined with transection of adductor muscle and transverse metatarsal l igament for treating mild or moderate hallux valgus through a single medial incision. Methods Between May 2006 and January 2009, 41 patients (45 feet) with mild or moderate hallux valgus were treated. There were 9 males (10 feet) and 32 females (35 feet) with an average age of 45.3 years (range, 23-71 years). The hallux valgus angle (HVA) was (33.1 ± 1.4)°, and the first and second inter-metatarsal angle was (20.4 ±1.1)°. The American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot score of the affected foot’s function was 47.2 ± 3.7. A longitudinal medial incision was made at the first metatarsophalangeal joint. By the incision, Austin metatarsal osteotomy and lateral soft tissue release (including transection of adductor muscle and the transverse metatarsal l igament) were performed at the same time. Results During operation, 1 case had superficial peroneal nerve branch injury and suture repair was done microsurgically. All incisions healed by first intention postoperatively. All patients were followed up 16-36 months (mean, 26 months). Medial forefoot numbness occurred in 2 feet at 3 days after operation and rel ieved within 6 weeks. The X-ray films showed bone heal ing at osteotomy site within 8 weeks after operation. At last follow-up, the HVA was (10.7 ± 1.7)°, showing significant difference when compared with preoperative value (t=22.32, P=0.00), and the first and second inter-metatarsal angle was (12.1 ± 1.7)°, also showing significant difference when compared with preoperative value (t=21.17, P=0.03). The postoperative AOFAS ankle and hindfoot score of the affected foot’s function was 84.9 ± 4.5, showing significant difference when compared with preoperative score (t=20.75, P=0.01). No foot hallux varus, hallux valgus, or metatarsal necrosis occurred during follow-up. Conclusion The Austin metatarsal osteotomy combined with transection of adductor muscle, transverse metatarsal l igament through a single medial incision can effectively correct the mild or moderate hallux valgus, and avoid the scar and injury of deep peroneal nerve branches by traditional lateral incision.
Objective To summarize the effectiveness of orthopedic surgery for patients with moderate and severe hallux valgus and analyze its related influencing factors. Methods A clinical data of 247 patients (287 feet) with moderate and severe hallux valgus, who were admitted between January 2013 and October 2024 and met the selection criteria, was retrospectively analyzed. There were 39 males and 208 females, with a median age of 57 years (range, 19-89 years). There were 207 cases of single-foot involvement and 40 cases of double-foot involvement; 159 feet were moderate hallux valgus and 128 feet were severe hallux valgus. The disease duration ranged from 3 months to 25 years, with a median of 5 years and 8 months. The hallux valgus angle (HVA), the intermetatarsal angle (IMA), proximal articular set angle (PASA), and the American Orthopaedic Foot and Ankle Society (AOFAS) scores were measured before operation and at 6 months after operation, and the differences (change values) between pre- and post-operation were calculated. All patients were grouped according to the degree of preoperative hallux valgus deformity and age, and the patients with severe hallux valgus according to different surgical procedures, and the change values of HVA, IMA, and AOFAS scores were compared between groups. All patients were grouped according to postoperative HVA, then the postoperative AOFAS scores were compared between groups. Results All patients successfully completed the operations and were followed up 6 months to 11 years and 3 months, with an average of 4 years and 6 months. The HVA, IMA, PASA, and AOFAS scores at 6 months after operation showed significant improvement compared to preoperative levels, and the differences were significant (P<0.05). The patients with severe hallux valgus had the higher change values of HVA, IMA, and AOFAS scores than the patients with moderate hallux valgus (P<0.05). The elderly patients had the highest change values of HVA and AOFAS scores than the young and middle-aged patients (P<0.05). The patients with postoperative HVA ranging from 0° to 5° had the highest AOFAS scores than the other patients at 6 months after operation (P<0.05). Among different surgical procedures for severe hallux valgus, the metatarsophalangeal joint fusion had the highest change value of HVA, the Scarf osteotomy had the highest performance in correcting the IMA, and the first metatarsal base osteotomy had the highest improvement in the postoperative AOFAS score, and the differences were significant (P<0.05). Conclusion Elderly patients show the better improvement in HVA and foot function after operation. The first metatarsal base osteotomy show the better improvement in foot function than other surgical procedures. A certain HVA is allowed to remain after hallux valgus correction, and the postoperative AOFAS score is higher when the corrected HVA is in the range of 0°-5°.
