- Abstract: BACKGROUND:Accurate reduction of ankle fractures under direct vision has become a common understanding among foot and ankle surgeons.How to fully expose free or compressed fragments of the posterior ankle remains one of the most challenging problems. OBJECTIVE:To explore the clinical efficiency of the para-Achilles tendon approach in exposing and repositioning the posterior malleolus sandwich fracture. METHODS:A retrospective study was made for 26 patients with posterior malleolus sandwich fracture treated with open reduction and internal fixation via para-Achilles tendon approach from January to December 2020 in The Second People's Hospital of Dalian.21 of 26 cases were managed with the lateral approach of Achilles tendon and 5 cases were managed with the medial approach of Achilles tendon.There were 19 males and 7 females,with the age of 24-69 years,averagely 38.6 years.The operation time and postoperative complications were recorded.The fracture reduction condition was evaluated by Burwell-Charnley imaging standard.Before operation,3 months after operation and last follow-up,visual analog scale score,ankle plantar flexion and dorsiflexion and American Orthopedic Foot&Ankle Society Ankle Hind Score were used to evaluate the treatment effect. RESULTS AND CONCLUSION:(1)All 26 patients were followed up for an average of 14.6 months(range 13-18 months).The operation time was 52-85 minutes(average 64.2 minutes).(2)Part of the skin edge of the lateral malleolus incision was necrotic in one patient and healed completely after a dressing change.Incision healing of the other patients was in one stage.(3)Through Burwell-Charnley imaging standard,anatomical reductions were obtained in 24 of 26,and good reductions were in 2 of 26,with an excellent and good rate of 100%.(4)At the last follow-up,the visual analog scale score(1.19±0.40)was significantly lower than the preoperative score(6.81±0.80)(P<0.01).Ankle plantar flexion(33.5±5.02)° and ankle plantar back stretch(17.23±0.99)° were significantly increased compared with preoperative data(14.58±2.50)° and(5.81±1.02)°(P<0.01).American Orthopedic Foot&Ankle Society Ankle Hind Score was improved to(89.31±3.62)points compared to preoperative(46.00±5.45)points(P<0.01).The results were excellent in 23 patients and good in 3 patients,with an excellent and good rate of 100%.(5)It is concluded that the open reduction and internal fixation via the para-Achilles tendon approach for the treatment of posterior malleolus sandwich fracture were efficient with decreased operation time,satisfying fracture reduction,fewer complications,satisfactory motion range,and functional recovery.
