OBJECTIVE: To determine the long-term results and possible complications of the posterior tibialis transfer in correction of the foot-drop in leprosy patients, and to compare the results by the circum-tibial and interosseous routes. METHODS: From January to October 2001, 37 cases (treated from October 1989 to October 1999) were followed up. Walking gait, active dorsiflexion and plantar flexion of the ankle joint, deformities of the feet, and patients’ satisfaction were recorded. RESULTS: Of 37 patients, 22 were treated by circum-tibial transfer, 15 by interosseous transfer. All patients’ Achilles tendons were lengthened. Excellent and good results were obtained in 30 cases (86%). The active dorsiflexion was better by interosseous route than by circum-tibial route. Out of 35 patients followed up for 2-11 years (4 years on average), 14 had talipes varus in 22 by circum-tibial transfer, 2 had talipes varus in 13 by interosseous transfer; there was significant difference between two routes (P lt; 0.05). The complications included drop-toe(5 cases), muscle atrophy (4 cases), tendon rupture (1 case) and tendon adhesion (1 case). CONCLUSION: Tibialis posterior transfer with elongation of tendo Achilles can obtain excellent results in treating foot-drop due to leprosy. Interosseous route is preferred and physiotherapy is emphasized pre- and postoperatively.
ObjectiveTo investigate the effectiveness of wide fascial and doubly vascularized pedicle posterior cnemis flap in repair of the soft tissue defect of forefoot.MethodsBetween March 2011 and March 2017, 18 cases with severe soft tissue defects of forefeet were repaired with the wide fascial and doubly vascularized pedicle posterior cnemis flaps. There were 13 males and 5 females with an average age of 33 years (range, 11-49 years). Of 18 cases, the defects were caused by trauma in 16 cases with an average disease duration of 15 hours (range, 3-72 hours), by infection after correction of spastic clubfoot in 1 case, and by infection after open fracture fixation in 1 case. The defects were on the planta of forefoot in 11 cases and on the dorsum of forefoot in 7 cases. The size of soft tissue defects ranged from 6 cm×4 cm to 15 cm×9 cm. All defects combined with the bone, joint, and tendon exposures and 4 defects combined with fractures. The size of flaps ranged from 8 cm×5 cm to 17 cm×10 cm. All wounds of donor sites were repaired by skin grafting.ResultsThe operation time was 100-190 minutes (mean, 140 minutes). Seventeen flaps survived and wounds healed by first intention. One flap had partial necrosis and cured after dressing change. Seventeen cases were followed up 5-24 months (mean, 16 months). Both the color and texture of the flaps were satisfactory. But the pedicles of flaps were swollen. The functions of foot and ankle returned to normal.ConclusionThe wide fascial and doubly vascularized pedicle posterior cnemis flap has reliable blood supply and sufficient venous reflux to ensure its survive, which can be used to repair severe soft tissue defect of forefoot.
Objective To investigate the effect of one stage arterialization of posterior tibial vein in treatment of peripheral arterial extensive occlusive disease. Methods Forty-six cases (56 limbs) of patients with peripheral arterial extensive occlusive disease were treated with one stage arterialization of posterior tibial vein. Results The symptom of pain disappeared right after one stage arterialization of posterior tibial vein in all patients . Skin temperature went up. The long-term results were satisfactory during the period of 3 months to 7 years follow-up, except two limbs were amputated and two limbs were reoperated with pedicle omental transplantation. Conclusion The technique of one stage arterialization of posterior tibial vein has advantages of one-stage procedure, various indications, little influence to venous return and rapid relief of ischemic symptoms.
Objective To assess the curative effect of the subtalararthrodesis on the serious subtalar joint with the posterior tibial tendon dysfunction.Methods From October 2000 to February 2006, 31 patients (18 males, 13 females; age 23-62 years, averaged 36.4years) with serious subtalar joint osteoarthrisis and stage Ⅱ posterior tibial tendon dysfunction were treated by the subtalar arthrodesis. The tibial tendon dysfunction involved 15 right and 16 left lower extremities, which were caused by retrograde osteoarthritis in 14 patients,sequel of an injury in 8 patients, infection in 7 patients, and anatomic structural abnormity in 2 patients. The treatment course averaged 9.5 months (range, 6-30 months). Before the subtalar arthrodesis, the injured tendons were repaired, and then the bone grafting was performed in the tarsus sinus. All of the patients were assessed before and after operation according to the Hindfoot scores system (American Orthopedics Foot and Ankle Society, AOFAS). Results Among the patients, 28 were followed up on an average of 23.6 months (range, 8-61 months). The AOFAS scores ranged from 45.30±1.08 before operation to 79.60±2.14 afteroperation. The pain indexes ranged from 15.40±2.23 before operation to 38.50±2.61 after operation. The functional indexes of the foot and ankle joint ranged from averaged 21.60±3.01 before operation to averaged 37.40±2.83 after operation. The statistical analysis of the t-test on all the above data showed that there was a significant difference between beforeoperation and after operation (P＜0.01). The angles between the longitudinal line of the talar and the calcaneal bone were 43.70±1.06° before operation and 29.40±0.98° after operation, and the deviation angles between the calcanealline and the talus were 48.20±0.85° before operation and 39.40±1.02° after operation. There was a significant difference between before operation and after operation (P＜0.01). Conclusion The subtalar arthrodesis combined with the bone grafting in the tarsus sinus and the repair of the injured tendons can effectivelycorrect the deformity of the deformity of the metapodium, relieve the pain, retin the adjacent joint motion ability, and this method can be recommended for the adult patient who suffers from serious subtalar osteoarthritis and stage Ⅱ osterior tibial tendon dysfunction.
ObjectiveTo evaluate the effectiveness of arthroscopic suture and absorbable screw double fixation for both anterior and posterior cruciate ligament avulsion fractures of tibial insertions. MethodsBetween June 2006 and September 2013, 8 patients with anterior and posterior cruciate ligament avulsion fractures of the tibial eminence underwent arthroscopic treatment with suture and absorbable screw double fixation. There were 5 males and 3 females, with a mean age of 28.9 years (range, 18-43 years). The causes of injury included traffic accident in 5 cases and falling from height in 3 cases. The time from injury to operation was 3-10 days (mean, 6.2 days). The Lysholm knee score, International Knee Documentation Committee (IKDC) score, and Tegner rating scales were used to evaluated the knee function. ResultsPrimary healing of incision was obtained, without infection or deep vein thrombosis. The mean follow-up period was 42.4 months (range, 24 to 65 months). At 3 months after operation, X-ray films showed good reduction and healing of fracture. The anterior and posterior drawer tests were negative. The knee range of motion was normal (0-125°), and it recovered to preoperative level in 7 cases. The IKDC score, Tegner score, and Lysholm score were significantly improved to 90.4±5.2, 7.5±1.6, and 89.2±3.5 from preoperative 52.1±3.3, 3.3±1.0, and 51.9±3.5 respectively (t=-38.680, P=0.000; t=-39.520, P=0.000; t=-41.150, P=0.000). ConclusionA combined injury of anterior and posterior cruciate ligament avulsion fractures of tibial insertions is rare. Arthroscopic treatment with suture and absorbable screw double fixation is a useful technique to restore tibial avulsion injuries with well-documented radiographic healing, good clinical outcomes, and low complication rates.
Ten cases of neurotmesis of posterior interosseous nerve of the forearm were treated with mierosurgical technique from Aug, 1988 to Oct. 1990, of which, 4 cases by autogenous nerve graft and 6 cases by direct neurosuture. Eight cases have been followed-up from 4 months to 1 year after operation concerning with satisfactory results. Some questions the diagnosis, the points for attention in operation, and the relation of the results and the time when the operation done were discussed. The comparison of the results and the recovery time between the autogenous-nerve graft and direct neurosuture was made.
ObjectiveTo systematically review the effectiveness of double-bundle versus single-bundle for arthroscopic transtibial reconstruction of posterior cruciate ligament (PCL). MethodsWe searched PubMed, The Cochrane Library, EMbase, VIP and WanFang Data to collect randomized controlled trials (RCTs) of PCL reconstruction treated with double-bundle versus single-bundle arthroscopic transtibial technique. Two reviewers screened literature according to the inclusion and exclusion criteria, extracted data and assessed the methodological quality of included studies, and then meta-analysis was performed by using RevMan 5.3 software. ResultsA total of 4 RCTs involving 186 patients were included. The results of meta-analysis showed that double-bundle was superior to single-bundle in Lysholm score (MD=2.17, 95%CI 0.29 to 4.05, P=0.02), Tegner score (MD=0.62, 95%CI 0.09 to 1.16, P=0.02), IKDC objective score (A:RR=1.57, 95%CI 1.09 to 2.26, P=0.02; A+B:RR=1.15, 95%CI 1.01 to 1.32, P=0.04). However, there was no significant difference in the KT-1000 posterior between both groups (MD=-0.65, 95%CI -3.29 to 1.99, P=0.63). ConclusionThe current evidence shows that the double bundle arthroscopic transtibial is superior to the single bundle PCL reconstruction. Due to the limited quality and quantity of the included studies, more high quality studies with large sample-size are needed to validate the conclusion.
ObjectiveTo explore the effectiveness of posterior unilateral transpedicular debridement, bone graft fusion, and pedicle screw fixation for thoracolumbar tuberculosis. MethodsBetween January 2009 and January 2013, 97 patients with thoracolumbar tuberculosis were treated with posterior unilateral transpedicular debridement, bone graft fusion, and pedicle screw fixation in 53 cases (group A), and with traditional posterior operation in 44 cases (group B). There was no significant difference in age, sex, disease duration, affected segments, Frankel grade, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), sagittal Cobb angle, visual analogue scale (VAS), and Oswestry disability index (ODI) between 2 groups (P>0.05). The surgery and follow-up results were compared between 2 groups. ResultsThe patients were followed up 24-60 months. All patients achieved intervertebral bone fusion after operation. The bone graft fusion time of groups A and B was (6.79±1.68) months and (6.89±2.00) months respectively, showing no significant difference (t=-0.251, P=0.802). There was no significant difference in operation time, intraoperation blood loss, and postoperative hospitalization time between 2 groups (P>0.05); the postoperative drainage volume of group A was significantly less than that of group B (P<0.05). The CRP and ESR at 1 year and the VAS score at last follow-up were significantly decreased when compared with preoperative values in 2 groups (P<0.05), but no significant difference was found between 2 groups (P>0.05). The Cobb angle at 1 week and at last follow-up and ODI at 3 months and at last followup were significantly improved in 2 groups (P<0.05), but there was no significant difference between the time points after operation (P>0.05). At 3 months after operation, the ODI of group A was significantly lower than that of group B (t=-2.185, P=0.027), but no significant difference was found in Cobb angle, Cobb angle loss, and ODI at other time points between 2 groups (P>0.05). At last follow-up, the Frankel classification of nerve function was improved 1-2 grades in 2 groups, showing no significant difference between 2 groups (Z=-0.180, P=0.857). No complication of internal fixation breakage or loosening was observed. ConclusionThe effectiveness of posterior unilateral transpedicular debridement, bone graft fusion, and pedicle screw fixation in the treatment of thoracolumbar tuberculosis is satisfactory, with the advantages of less trauma, strong spinal stability, and fast function recovery.
Objective To evaluate and compare the outcomes of simple closed reduction, selective fragment excision after closed reduction, and emergency fragment excision and reduction in the treatment of Pipkin type I fracture of femoral head associated with posterior dislocation of the hip. Methods Between January 2002 and January 2008, 24 patients with Pipkin type I fracture of the femoral head associated with posterior dislocation of the hip were treated with simple closed reduction (closed reduction group, n=8), with selective fragment excision after closed reduction (selective operation group, n=8), and with emergency fragment excision and reduction (emergency operation group, n=8). In the closed reduction group, there were 6 males and 2 females with an average age of 37.6 years (range, 19-56 years); injuries were caused by traffic accident in 6 cases, by fall ing from height in 1 case, and by crushing in 1 case with a mean disease duration of 3.1 hours (range, 1.0-7.5 hours); and the interval from injury to reduction was (4.00 ± 2.14) hours. In the selective operation group, there were 7 males and 1 female with an average age of 37.3 years (range, 21-59 years); injuries were caused by traffic accident in 7 cases and by fall ing from height in 1 case with a mean disease duration of 3.2 hours (range, 1.0-6.0 hours); and the interval from injury to reduction was (3.90 ± 1.47) hours. In the emergency operation group, there were 5 males and 3 females with an average age of 35.5 years (range, 20-58 years); injuries were caused by traffic accident in 5 cases, by fall ing from height in 1 case, and by crushing in 2 cases with a mean disease duration of 3.3 hours (range, 1.5-6.5 hours); and the interval from injury to open reduction was (5.10 ± 2.04) hours. There was no significant difference in the age, gender, disease duration, and interval from injury to reduction among 3 groups (P gt; 0.05). Results All wounds in selective operation group and emergency operation group healed primarily. All the patients were followed up 24 to 58 months (mean, 38.7 months). According to Thompson-Epstein system, the excellent and good rates were 50.0% (4/8) in the closed reduction group, 87.5% (7/8) in the selective operation group, and 87.5% (7/8) in the emergency operation group at 24 months after operation, showing significant difference among 3 groups (χ2=9.803, P=0.020). Heterotopic ossification was found in 1 case (12.5%) of the closed reduction group, in 4 cases (50.0%) of the selective operation group, and in 4 cases (50.0%) of the emergency operation group, and avascular necrosis of femoral head was found in 2 cases (25.0%) of the closed reduction group; there was no significant difference in compl ications among 3 groups (P gt; 0.05). Conclusion The treatment of Smith-Petersen approach and fragment excision by selective operation or emergency operation has similar outcome, which are better than the treatment of simple closed reduction.
Objective To investigate the effectiveness of arthroscopically assisted treatment of acute tibial insertion avulsion fracture of the posterior cruciate ligament (PCL) via posteromedial incision. Methods Between January 2010 and January 2012, 22 patients with acute tibial insertion avulsion of the PCL underwent arthroscopic reduction and fixation via posteromedial incision. There were 14 males and 8 females with an average age of 32 years (range, 18-48 years). The injury causes included traffic accident injury in 14 cases, sport injury in 4 cases, and falling injury in 4 cases. The disease duration ranged from 7 to 16 days (mean, 10 days). Of 22 patient, 14 had simple PCL injury, 6 had PCL injury with meniscus injury, and 2 with cartilage injury. The results of posterior drawer test were positive in all patients. The preoperative Lysholm score was 51.1 ± 3.4. Results All incisions healed by first intention without infection, deep venous thrombosis of lower limbs, or vessel and nerve injuries. All patients were followed up 12-24 months (mean, 18.4 months). X-ray films showed that all fractures healed with the healing time of 2-4 months (mean, 3 months). The Lysholm score was improved to 96.0 ± 2.2 at 6 months after operation, showing significant difference when compared with preoperative score (t=43.020, P=0.000). Conclusion Arthroscopically assisted treatment of acute tibial insertion avulsion fracture of the PCL via posteromedial incision is a safe, easy, and effective method.
