OBJECTIVE To introduce the surgical procedure and clinical result of microsurgical repair on collateral ligament rupture in the interphalangeal joint using superficial flexor tendon of finger. METHODS From 1987, 23 cases with collateral ligament rupture in the interphalangeal joint were repaired by part of superficial flexor tendon of finger. The initial point of collateral ligament was drilled two holes, 2 to 3 mm in distance, and crossed by steel wire. Then the superficial flexor tendon of finger was crossed under the steel wire and sutured to the terminal point of superficial flexor tendon of finger by 5/0 to 7/0 nontraumatic suture thread to maintain suitable tension, and sutured to collateral ligament by 8/0 nontraumatic suture thread. Extension splint fixation was performed 4 to 6 weeks postoperatively. RESULTS Followed up 3 to 6 months, 15 cases were excellent, 6 cases were better, 2 cases were moderate, and the excellent rate was 91.34% according to Saetta standard. CONCLUSION Microsurgical repair on collateral ligament rupture in the interphalangeal joint using superficial flexor tendon of finger is a convenient and effective surgical method.
Objective To compare the functional and radiological outcomes of supramalleolar osteotomy (SMOT) between with and without fibular osteotomy for varus ankle osteoarthritis. Methods Between April 2009 and April 2014, 41 patients (41 feet) with mid-staged varus ankle osteoarthritis were treated with SMOT. Fibular osteotomy was not performed in 19 cases (group A), and fibular osteotomy was performed in 22 cases (group B). There was no significant difference in gender, age, side, body mass index, osteoarthritis stage, pathogeny, American Orthopedic Foot and Ankle Society (AOFAS) ankle-hind score, ankle osteoarthritis scale (AOS) pain and function scores, range of motion (ROM) of the ankle joint, tibial articular surface angle (TAS), talar tilt angle (TT), tibiocrural angle (TC), and tibial lateral surface angle (TLS) between 2 groups (P>0.05). The bone union was observed after operation, and functional and radiological outcomes were compared between 2 groups at last follow-up. Results All incisions healed by stage I, and no surgery related complications occurred. The mean follow-up time was 36.6 months (range, 16-55 months). Pain and limited activity were observed in 1 case of groups A and B respectively, and ankle arthrodesis was performed. All cases achieved bony union; the bone union time was (3.6±0.4) months in group A and (3.9±0.7) months in group B, showing no significant difference (t=1.61,P=0.12). At last follow-up, no significant difference was found in TAS, TLS, TT, and TC between groups (P>0.05). However, group B was significantly better than group A in improvement of TT and TC (P<0.05). The AOFAS ankle-hind score, AOS pain and function scores, ROM of the ankle joint showed no significant difference between groups (P>0.05). According to the modified Takakura stage, the improvement rates of groups A and B were 55.6% and 57.1%, respectively; no significant difference was found between 2 groups (χ2=0.01,P=0.92). Conclusion SMOT with fibular osteotomy is helpful in correction of TT and TC in patients with relative longer fibula.
ObjectiveTo summarize the technique and effectiveness of double metatarsal osteotomy for treating severe hallux valgus with increased distal metatarsal articular angle (DMAA).MethodsBetween June 2014 and December 2017, 64 patients (94 feet) of severe hallux valgus with an increased DMAA were treated with the double metatarsal osteotomy (distal metatarsal Reverdin osteotomy+proximal metatarsal open wedge osteotomy) combined with Akin osteotomy and soft tissue surgery to correct the deformity. There were 10 males (15 feet) and 54 females (79 feet) with an average age of 44.5 years (range, 26-66 years), including 34 of unilateral foot and 30 of bilateral feet. The Maryland metatarsophalangeal joint score of the American Orthopaedic Foot and Ankle Society (AOFAS) was 54.3±7.4 and the visual analogue scale (VAS) score was 6.0±2.0. The pre- and post-operative AOFAS score, VAS score, DMAA, hallux valgus angle (HVA), first-second intermetatarsal angle (1-2IMA), and the first metatarsal length (FML) were recorded and compared.ResultsAll incisions healed by first intention. All patients were followed up 12-15 months, with an average of 13.2 months. The complications occurred in 4 feet, including 1 foot of hallux stiffness, 1 foot of numbness at the edge of the wound, 1 foot of metastatic metatarsalgia, and 1 foot of metatarsal bone necrosis. At 1 year after operation, the Maryland metatarsal joint score of AOFAS was 89.2±7.4, showing significant difference compared with preoperative score (t=18.427, P=0.000); and the effectiveness was rated as excellent in 78 feet, good in 12 feet, poor in 3 feet, and bad in 1 foot, with an excellent and good rate of 95.7%. The VAS score was 1.5±2.0, showing significant difference compared with the preoperative score (t=10.238, P=0.000). The X-ray films showed that the osteotomies achieved bony healing at 3 months after operation. There were significant differences (P<0.05) in HVA, 1-2IMA, and DMAA between preoperation and 6 months and 1 year after operation; but no significant difference was found in FML between preoperation and 1 year after operation (t=0.136, P=0.863).ConclusionFor the patients with severe hallux valgus with increased DMAA, the double metatarsal osteotomy can significantly relieve the clinical symptoms and improve the imaging parameters with less postoperative complications.
An elderly female patient, with systemic multiple organ dysfunction, suffered from severe aortic valve stenosis, was to undergo transcatheter aortic valve replacement (TAVR). She was intolerance of the computed tomography examination before surgery. Bedside echocardiography was employed to evaluate the patient’s aortic valve stenosis, valve anatomy and type, the condition of aortic root, the distance from coronary to aortic root, and lower-extremity vascular access. Finally, the emergent TAVR was successfully performed under general anesthesia, and the aortic valve trans-prosthetic gradient met a remarkable decrease after surgery.
Objective To review targeted muscle reinnervation (TMR) surgery for the construction of intelligent prosthetic human-machine interface, thus providing a new clinical intervention paradigm for the functional reconstruction of residual limbs in amputees. MethodsExtensively consulted relevant literature domestically and abroad and systematically expounded the surgical requirements of intelligent prosthetics, TMR operation plan, target population, prognosis, as well as the development and future of TMR. Results TMR facilitates intuitive control of intelligent prostheses in amputees by reconstructing the “brain-spinal cord-peripheral nerve-skeletal muscle” neurotransmission pathway and increasing the surface electromyographic signals required for pattern recognition. TMR surgery for different purposes is suitable for different target populations. Conclusion TMR surgery has been certified abroad as a transformative technology for improving prosthetic manipulation, and is expected to become a new clinical paradigm for 2 million amputees in China.
【Abstract】Objective To investigate prophylactic measures for nontraumatic complications of laparoscopic cholecystectomy (LC).Methods The data of 13 000 patients who underwent LC in Kunming general hospital of PLA over 13 years(1991-2004) were retrospectively reviewed. Results Nine malignant tumors and 47 common bile duct stones were missed at LC. The 9 malignant tumors included hepatic cancer (n=1), gastric cancer (n=1), gallbladder cancer (n=2), pancreatic cancer (n=2) and right colon cancer (n=3). Of all the carcinomas, 3 patients with right colon cancer underwent colectomy, the other 6 patients couldn’t be cured radically. All the 47 patients with choledocholithiasis were cured successfully, among them 31 patients were performed with ERCP and 16 were reoperated on with cholangiotomy. Conclusion This study emphasizes the necessity to analyze carefully patients’ symptoms before operation and pay attention to pathological changes of gallbladder and intraabdominal situation intraoperatively. If necessary, laparoscopic ultrosonography can be used to avoid missing malignant tumors and biliary stones.
