RESUMO
Objective To explore the efficacy of Krackow locking loop technique combined with the modified Kessler suture technique in the treatment of acute closed Achilles tendon rupture.Methods From January 2020 to January 2022,162 cases of acute closed Achilles tendon rupture were treated with Krackow locking loop technique combined with the modified Kessler suture technique.The patients were treated with the same postoperative rehabilitation plans.The American Orthopaedic Foot and Ankle Society(AOFAS)hindfoot score and Achilles Tendon Total Rupture Score(ATRS)were collected to evaluate the functions.Results The operation time was 24-40 min(mean,31.9±4.6 min).All incisions healed in one stage without infection or sural nerve injury.Complications occurred in 2 patients,including 1 case of deep venous thrombosis and 1 case of trauma-related re-rupture.The recovery time of ankle flexion and extension motion was4-12 weeks(mean,7.6±1.9 weeks),the recovery time of single-legged heel rise height on the affected side was 10-18 weeks(mean,13.3±1.8 weeks),and the recovery time of fast walking or jogging was 14-26 weeks(mean,19.1±1.8 weeks).The 162 patients was followed up for 14-25 months(mean,19.0 months).The AOFAS hindfoot score increased from(54.4±4.4)points preoperatively to(98.0±4.0)points at the last follow-up(t =-104.402,P =0.000).The ATRS score increased from(52.0±8.3)points preoperatively to(91.2±2.4)points at the last follow-up(t =-62.823,P = 0.000).Conclusions For young and middle-aged patients with acute closed Achilles tendon rupture,Krackow locking loop technique combined with the modified Kessler suture technique can achieve good clinical outcomes.Early functional exercise is required to return to work and life.
RESUMO
Objective:To compare percutaneous cannulated screw (PCS) fixation and plating via a minimally invasive longitudinal approach (MILA) after closed reduction for the treatment of intra-articular tongue-type calcaneal fractures.Methods:A retrospective analysis was conducted of the 67 patients with intra-articular tongue-type calcaneal fracture who had been treated at Department of Orthopedics, The Third Hospital of Peking University from May 2017 to May 2020. They were 56 males and 11 females, 19 to 58 years of age (average, 34.5 years). Of them, 32 were treated by the PCS fixation after closed reduction (PCS group) and 35 by the MILA plating after closed reduction (MILA group). The operation time, preoperative time, post-operative hospital stay, blood loss and postoperative complications were recorded and compared between the 2 groups. The calcaneal length, width and height, Gissane angle, B?hler angle, varus angle, valgus angle and visual analog scale (VAS) were compared between the 2 groups at preoperation, immediate postoperation, 3 months postoperation, and the last follow-up. The American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score was used at 3 months postoperation and the last follow-up to evaluate the function of the injured hindfoot.Results:There was no significant difference in the preoperative general data between the PCS group and the MILA group, showing they were comparable ( P>0.05). All patients were followed up for an average of 18.5 months (from 15 to 25 months). For the PCS group and the MILA group, respectively, the operation time was 60.5 (51.5, 68.0) min and 86.0 (78.0, 96.0) min, the blood loss 10 (5.0, 20.0) mL and 20 (15, 25) mL, the postoperative hospital stay 1 (1.0, 1.8) d and 2 (2, 3) d, the calcaneal width at immediate postoperation (43.8±4.4) mm and (40.6±2.8) mm, the calcaneal width at 3 months postoperation 43.8 (39.6, 48.3) mm and 41.5 (38.8, 44.5) mm, the calcaneal width at the last follow-up 44.2 (40.2, 48.0) mm and 41.3 (39.0, 44.3) mm, the VAS at the last follow-up 5.0 (5.0, 5.0) and 6.0 (5.0, 6.0). The comparisons of the above items showed significant differences between the 2 groups (all P<0.05). No significant differences were observed between the 2 groups in the calcaneal length or height, Gissane or B?hler angle, AOFAS hindfoot score, or complication rate (all P>0.05). Conclusions:In the treatment of tongue-type calcaneal fractures, after closed reduction, the PCS fixation can shorten operation time and postoperative hospital stay, and reduce intraoperative blood loss and postoperative pain, but the MILA plating is more advantageous in restoring the calcaneal width.
