ABSTRACT
Objective:To evaluate the clinical effects of anatomical reconstruction of the deltoid ligament and medial migration calcaneal osteotomy in the treatment of chronic ankle instability after trauma.Methods:A retrospective study was conducted to analyze of the clinical data of 16 patients with chronic post-traumatic instability of the medial malleolus who had been treated at The Eighth Department of Orthopedics, Foshan Hospital of Traditional Chinese Medicine from December 2015 to February 2017. There were 14 males and 2 females with an age of (28.1±4.2) years. Seven left sides and 9 right sides were affected; the time from injury to operation was (8.9±2.4) months. Before operation, X-rays (anteroposterior, lateral and Saltzman views) and MRI of weight-bearing ankle were taken. All patients were treated by anatomical reconstruction of the deltoid ligament using the autologous semitendinosus and medial migration osteotomy of the calcaneus. The time for injury healing and occurrence of complications were recorded. The talus tilt angle, Meary angle, hindfoot valgus angle, visual analogue scale (VAS), and the American Orthopedic Foot & Ankle Society (AOFAS) ankle-hindfoot function score were compared between the preoperation and the last follow-up. The Sefton evaluation for efficacy in ankle ligament reconstruction was used to assess stability of the ankle joint.Results:Of this cohort, 14 patients were followed up for (16.4±4.9) months after operation and 2 patients lost to follow-up. The 14 patients all returned to normal physical activities 3 months after operation. All incisions healed at the first stage with no infection. One patient experienced pain at the site for harvest of the semitendinosus but the symptoms were relieved after rehabilitation treatment like massage and physical therapy. At the last follow-up, the talus tilt angle [1.0 (0.0, 2.0)°], Meary angle (1.4°±4.2°), hindfoot valgus angle (3.2°±2.4°), VAS score [0.5 (0.0, 1.0) points], and AOFAS ankle-hindfoot score [(89.2±6.1) points] were all significantly improved compared with the preoperative values [8.3°±1.8°, 0.8°±3.8°, 9.9°±3.4°, (5.7±2.5) points, and (49.6±9.8) points] (all P<0.05). According to the Sefton evaluation, the stability of the ankle joint was excellent in 9 cases, good in 4 cases, and fair in 1 case. Conclusion:In the treatment of chronic ankle instability after trauma, anatomical reconstruction of the deltoid ligament and medial migration calcaneal osteotomy is safe and effective, resulting in limited complications.
ABSTRACT
Objective:To study the efficacy of minimally PCWO combined with Akin osteotomy on severe hallux valgus.Methods:This retrospective study was conducted on 45 patients (50 feet) with severe hallux valgus treated by minimally PCWO combined with Akin osteotomy in Eight Department of Bone, Foshan Hospital of traditional Chinese Medicine from August 2016 to August 2018. HVA, IMA, DMAA, DASA, IPA were measured by X-ray examination preoperatively and after operative 3, 6, 12 months and at the final follow-up. The efficacy was evaluated in accordance with the American Orthopaedic Foot and Ankle Association (AOFAS) Ankle Hindfoot Scale and the Olerud-Molander Ankle (OMA) Score. The absolute and relative lengths of the first metatarsus were measured by X-ray examination preoperatively and at the last follow-up, with calculating the differences.Result:All patients were followed up within 18.20±2.04 months. There was no recurrence during follow-up period. HVA was 42.83°±4.63°, 12.83°±1.53°, 13.49°±1.33°, 14.08°±1.49° and 14.12°±1.35° at the preoperative, postoperative 3 months, 6 months, 12 months and the last follow-up, respectively, and the difference between pre-operation and post-operation was statistically significant ( P<0.05). IMA was 18.29°±0.94°, 7.84°±1.22°, 8.31°±1.03°, 9.01°±1.08° and 9.09°±1.11° at the preoperative, postoperative 3 months, 6 months, 12 months and the last follow-up, respectively, and the difference between pre-operation and post-operation was statistically significant ( P<0.05). AOFAS scores were 50.64±7.94, 88.80±2.68, 90.10±3.51, 91.20±3.89 and 91.37±3.71 points at the preoperative, postoperative 3 months, 6 months, 12 months and the last follow-up, respectively, and the difference between pre-operation and post-operation was statistically significant ( P<0.05). The OMA scores were 61.00±7.00, 90.90±5.02, 91.60±4.57, 93.20±3.61 and 93.48±4.91 at preoperative, postoperative 3 months, 6 months, 12 months and the last follow-up, respectively, and the difference between pre-operation and post-operation was statistically significant ( P<0.05). The absolute shortening of the first metatarsal was 3.03 mm and relative shortening was 0.72 mm. Conclusion:For severe hallux valgus, minimally PCWO combined with Akin osteotomy can effectively correct the hallux valgus deformity with small surgical incision, high safety and curative effect, which is worthy of popularization and application in clinical.
ABSTRACT
Objective:To evaluate three-stage induced membrane technique combined with anterior and posterior double-plate fixation in the treatment of a total talus defect after infection.Methods:Included in this study were 11 patients with talus infection who had been treated at Department of Orthopaedics, Foshan Hospital of Traditional Chinese Medicine from January 2014 to December 2018. They were 8 males and 3 females, aged from 23 to 63 years (mean, 37.0 years). The infection followed re-implantation after open dislocation of total talus in 4 cases, internal fixation for open talus fracture of Gustilo type Ⅲa in 3 cases and surgery of open ankle fracture of Gustilo type Ⅲc in 2 cases, and was complicated with ankle intraarticular tuberculosis in 2 cases. The three-stage operations consisted of debridement, total talus resection, implantation of antibiotic bone cement and vacuum sealing drainage at the first stage, change of bone cement, re-debridement, wound closure or flap covering at the second stage 7 to 10 days later, and reconstruction after infection control using anterior and posterior double-plate fixation and induced membrane technique at the third stage 6 to 12 weeks later. Assessment of lower limb shortening was performed by comparing the full length of the leg between the normal and affected sides; the functions were assessed by comparing the ankle-hindfoot scores of American Orthopedic Foot and Ankle Society (AOFAS) and visual analogue scale (VAS) between preoperation and the final follow-up.Results:The 11 patients were followed up for an average of 24.3 months (from 12.2 to 37.5 months). Superficial skin necrosis was observed in 2 patients and injury to superficial peroneal nerve in one. Absolute calcification of the autograft area was observed in all patients, leading to ankle fusion. The final follow-ups observed no significant difference in the full length of the leg between the normal and affected sides [(380.4±35.5) mm versus (376.3±32.8) mm] ( P>0.05) , a significant increase in the ankle-hindfoot AOFAS scores from preoperative 28.0±3.4 to 72.8±5.4, and a significant decrease in VAS scores from preoperative 5(5,6) to 0(0,1) (all P<0.05). Slight varus developed in 2 patients and slight ankle stiffness in 3; recurrence of infection or breakage of implants was found in none of the patients. Conclusion:Three-stage induced membrane technique combined with anterior and posterior double-plate fixation can effectively control infection of the talus, maintain the length and reconstruct the function of the lower limb after a total talus defect.
