ObjectiveTo investigate the surgical method and preliminary effectiveness of Ilizarov technique in the treatment of lower limb deformity caused by achondroplasia. MethodsThe clinical data of 38 patients with lower limb deformity caused by achondroplasia treated by Ilizarov technique between February 2014 and September 2021 were retrospectively analyzed. There were 18 males and 20 females, the age ranged from 7 to 34 years, with an average of 14.8 years. All patients presented with bilateral knee varus deformity. The preoperative varus angles was (15.2±4.2)°, and knee society score (KSS) was 61.8±7.2. Nine of these patients underwent tibia and fibula osteotomy, 29 cases underwent tibia and fibula osteotomy and bone lengthening at the same time. Full-length bearing position X-ray films of bilateral lower limbs were taken to measure the bilateral varus angles, analyze the healing index, and record the occurrence of complications. KSS score was used to evaluate the improvement of knee joint function before and after operation. Results All 38 cases were followed up 9-65 months, with an average of 26.3 months. Needle tract infection occurred in 4 cases and needle tract loosening occurred in 2 cases after operation, which were improved after symptomatic treatment such as dressing change, Kirschner wire change, and oral antibiotics, and no neurovascular injury occurred in all patients. The external fixator was worn for 3-11 months after operation, with an average of 7.6 months, and the healing index was 43-59 d/cm, with an average of 50.3 d/cm. At last follow-up, the leg was 3-10 cm longer, with an average of 5.5 cm. The varus angles was (1.5±0.2)° and the KSS score was 93.7±2.6, which significantly improved when compared with those before operation (P<0.05). ConclusionIlizarov technique is a safe and effective method for the treatment of short limb with genu varus deformity caused by achondroplasia, which can improve the quality of life of patients.
Objective To evaluate the cl inical effect of percutaneous transluminal angioplasty (PTA) and PTA and stenting (PTAS) in treating multilevel arteriosclerosis obl iterans (ASO) of lower extremities. Methods Between January 2007 and October 2009, 29 cases of multilevel ASO of lower extremities were treated with PTA or PTAS. There were 17 males and 12females with an average age of 71 years (range, 56-83 years). The cl inical manifestations were l imbs numb with cold sensation, intermittent claudication (lt; 100 m), and 19 patients had rest pain. According to Fontaine stages classification, there were 7 cases of stage II, 14 cases of stage III, and 8 cases of stage IV. Concomitant diseases included hyperl ipidemia in 13 cases, diabetes in 6 cases, hypertension in 12 cases, chronic heart failure in 5 cases, chronic obstructive pulmonary disease in 3 cases, cerebral infarction in 5 cases, and toe ulcer in 15 cases. The preoperative ankle/brachial index (ABI) was 0.28 ± 0.13. Results In 3 cases of below knee lesions for the guide wire puncturing through the artery wall, 1 case gave up, and 2 cases continued recanal ized other arteries without serious bleeding compl ications. After operation, cerebral infarction occurred in 1 case, pulmonary infection in 2 cases, and groin puncture site hematoma in 2 cases. All patients were followed up 3 to 36 months. Limb skin temperature was significantly improved, and intermittent claudication disappeared or claudication distance lengthened, rest pain disappeared or significantly reduced in 27 patients (30 l imbs). The wound of amputee achieved good heal ing in 2 cases (2 l imbs). In 27 patients undergoing endovascular treatment, the postoperative ABI was 0.72 ± 0.19, showing significant difference when compared with the preoperative one (P lt; 0.05). Conclusion The PTA and PTAS treatment for multilevel ASO of lower extremities is a safe and effective option, and the short-term effect is good. Different treatments should be chosen according to the location and length of vascular occlusion.
【Abstract】 Objective To explore the effectiveness of bone grafting by intervertebral disc endoscope for postoperativenonunion of fracture of lower limb. Methods Between August 2004 and August 2008, 40 patients (23 males and 17 females) with postoperative nonunion of femoral and tibial fracture, aged 20-63 years (mean, 41.5 years) were treated. Nonunion of fracture occurred at 10-16 months after internal fixation. During the first operation, the internal fixation included interlocking intramedullary nail ing of femoral fracture in 12 cases and plate in 16 cases, and interlocking intramedullary nail ing of tibial fractures in 9 cases and plate in 3 cases. The X-ray films showed hypertrophic nonunion in 24 cases, common nonunion in 3 cases, and atrophic nonunion in 13 cases. Results The average operation time was 61 minutes (range, 40-80 minutes), and the blood loss was 80-130 mL (mean, 100 mL). The hospital ization time were 6-11 days (mean, 8.1 days). Incisions healed by first intention in all patients with no complication of infection or neurovascular injury. Forty patients were followed up 10-16 months (mean, 12.3 months). The X-ray films showed that all patients achieved healing of fracture after 4-10 months (mean, 6.8 months). No pain, disfunction, or internal fixation failure occurred. Conclusion Bone grafting by intervertebral disc endoscope is an effective method for treating postoperative nonunion of femoral and tibial fracture.
Objective To analyze the characteristics of patients with secondary lower limb deformity of spina bifida based on the QIN Sihe Orthopedic Surgery Case Data, and provide the references for clinical research, diagnosis, and treatment. Methods A clinical data of 1 012 patients with secondary lower limb deformity of spina bifida between October 12, 1986 and December 31, 2020 selected from QIN Sihe Orthopedic Surgery Case Data was retrospectively analyzed. Among them, 231 cases (22.83%) had undergone orthopedic surgery for lower extremity deformities in other hospitals. The gender, age at surgery, indicators related to spina bifida (deformity side, comorbidity, sensory disturbance level), and information related to surgery (operating time, surgical site, postoperative fixation method) were analyzed. Results Of the 1012 patients, 457 were males and 555 were females. The age was 3-51 years at the time of surgery, with a median of 18.0 years; among them, the 15-30 years old group had the most patients, accounting for 53.16%. Most deformities involved both lower limbs (652 cases, 64.43%). There were 111 cases of ulcers in the weight-bearing area of the foot, 265 cases of gatism, 554 cases of sensory disturbance, and 85 cases of abnormal hair on the waist. From 2010 to 2019, there were significantly more patients undergoing surgery than before 2010, reaching 61.17%. Sensory disturbances mostly occurred in the ankle and foot. A total of 1 149 sites were treated with surgery, of which the most ankle joint deformities were corrected by surgery, accounting for 84.33%. The main fixation methods after orthopedic surgery were external fixation, including Ilizarov external fixation (442 cases), combined external fixation (315 cases), and plaster fixation (189 cases). Conclusion Spina bifida can be secondary to severe deformities of the lower limbs, mainly in the ankles. Common complications include ulcers in the weight-bearing area, dysfunction of urine and feces, and sensory disturbances; external fixation is the main method of fixation after surgery.
Objective To study efficacy of ligation and stripping of great saphenous vein in combination with foam sclerotherapy and foam sclerotherapy alone in treatment of venous leg ulcer. Method Fifty-seven patients with venous leg ulcers from January 2015 to December 2016 in the West China Hospital of Sichuan University were collected, then were designed to ligation and stripping of great saphenous vein in combination with foam sclerotherapy group (abbreviated as combination therapy group, n=33) and foam sclerotherapy alone group (n=24). Results The baseline data such as the age, gender, disease duration, and ulcer size had no significant differences in these two groups (P>0.05). All the patients received operation successfully. The median operative time was shorter, the average intraoperative blood loss was less, and the time of ulcer healing after surgery was longer in the foam sclerotherapy alone group as compared with the combination therapy group [14 minversus 40 min, P<0.001; (12.3±3.2) mLversus (35.5±10.0) mL, P<0.001; (22.0±4.5) dversus (13.7±4.0) d, P<0.001]. The rates of the wound infection, local pigmentation, and ulcer recurrence had no significant differences between the foam sclerotherapy alone group and the combination therapy group (4.2%versus 9.1%, P=0.472; 25.0% versus 15.2%, P=0.352; 20.8% versus 9.1%, P=0.208). The foam sclerotherapy alone group was obviously superior to the combination therapy group in the time and cost of hospitalization (4 d versus 13 d, P<0.001; 3 000 yuanversus 8 590 yuan, P<0.001). There was no large area of tissue necrosis, the deep vein thrombosis, or the other serious complications in these two groups. Conclusion Ligation and stripping of great saphenous vein in combination with foam sclerotherapy in treatment of venous leg ulcer can accelerate ulcer healing than foam sclerotherapy alone, but there is no significant difference between these two groups in complications and recurrence rate, the foam sclerotherapy alone group is superior in time and cost of hospitalization, appropriate treatment plan should be formulated according to specific situation of patient.
Objective To evaluate the efficiency and safety of combinative use of radiofrequency and transilluminated powered phlebectomy for treatment of varicose veins of lower extremity. Methods Three hundred and twenty-one cases of varicose veins of lower extremity were randomly divided into three groups: group A (102 cases)： endovenouser whole range closure in situ for great saphenous vein by radiofrequency and transilluminated powered phlebectomy for varicose veins of leg; group B (97 cases)： endovenouser whole range closure in situ for upper leg part of great saphenous vein by radiofrequency and transilluminated powered phlebectomy for varicose veins of leg; 122 conventional treatment cases, which high ligation and stripping of great saphenous vein, blood vessel branches and communicating branches resection and ligation were used, were selected as controlled group (group C). Consequences and complications of operation were checked. Results In all cases, the symptoms of swelling in lower extremity, soreness and infirmity disappeared within one month after operation, skin pigmentation was alleviated within one month after operation, and disappeared gradually within three months. Contrasting three groups in complications of skin numbness of legs, ecchymosis of upper leg, wound hematoma, and swelling below ankle, there was no statistical difference between group A and B, and there was statistical difference between group A and C, and B and C. There were more complications in conventional group than those in mini-invasive groups. There was no statistical difference in leg ecchymosisa between group B and C. No deep vein thrombosis of lower extremity and incision infection was detected in all cases. Conclusion It is simple and definitely efficient to combine radiofrequency with transilluminated powered phlebectomy for treatment of varicose veins of lower extremity. Powered phlebectomy is efficient in removal of varicose vein, but not suitable for phlebectomy for trunk of great saphenous vein.
