Posteromedial peroneal tendon groove deepening treatment of the chronic subluxation of the peroneal tendons / 中华骨科杂志

ABSTRACT

Objective To investigate the clinical curative result of the new method of postermedial deepen of the fibular groove in the treatment of chronic peroneal tendon subluxation.Methods From March 2006 to October 2012,21 patients (15 male,6 female) with chronic peroneal tendon subluxation via a novel method of postermedial deepen of the fibular groove.In this groupⅠ grade 5 cases;Ⅱ grade 9 cases;Ⅲ grade 5 cases;Ⅳ grade 2 cases.All patients were followed up for at least 24 months.The American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot scale score and visual analogue score (VAS) were used to evaluate the clinical outcomes.Operation time,time to heal and complications were also recorded.Results The average operation time was 50 minutes (30-70 minutes).The blood loss was 30-60 ml,average 40 ml.All incisions healed after operation,no case of incision infection,skin necrosis and sural nerve,vascular injuryed.Mean AOFAS score was significantly increased from (55.2±7.1) preoperative to (93.6±5.6) postoperative.15 patients with excellent,good for 1 cases.The excellent and good rate was 100％ (16/16).VAS score by an average of (5.3±2.1) points down to (1.2±1.1) points postperative.All the patients can wear normal shoes postoperative,waking with normal gait.No patients had peroneal tendon tenosynovitis,tendon adhesion,fracture of lateral malleolus and other serious complications,no dislocation recurrent,strength of the peroneal muscle returns to normal.Conclusion The novel method of postermedial deepen of the fibular groove in the treatment of chronic peroneal tendon subluxation was safe and effective for ankle instability with a relatively short time.
