Abstract:
Objective To explore the effect of the treatment for the old deltoid ligament injuries by TwinFix suture anchors fixation along with overlap suturing.Methods Totally the data of 17 patients with old deltoid ligament injury was retrospectively reviewed who received treatment from January 2007 to December 2011.There were 11 males and 5 females,with an average age of 32.1 years (range,18-58 years).All of them had ankle sprain histories with the duration ranging from 7-25 months (average,14.2 months).All patients received weight-bearing X-ray,bilateral anterior-posterior (AP) and oblique radiography,MRI and ultrasound examinations before operation.Further arthroscopic examination was performed to confirm the diagnosis and debrided the intra-articular proliferative synovial tissue as well as injured articular cartilage for the patients after they were diagnosed with deltoid ligament injury.Open surgeries were performed though an incision on the medial ankle space.Residual ligament and scar tissue were cleaned.Old avulsion fractures of medial ankle tip were removed in 2 cases.The deep layer of ruptured deltoid ligament was sutured onto the tip of medial malleolus while the superficial layer was overlapped and sutured to the periosteum of medial ankle.Anchors were then utilized to fix the ligament.The clinical outcomes were evaluated based on American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hiodfoot score system.Results The follow-up duration of the 17 patients were 12-34 months with an average of 20.1 months.Both image evidences and intraoperative findings revealed the injury and scarring of deltoid ligament.The angle between long axis of talus and first metatarsal and the angle of hindfoot alignment in Saltzrnan view reduced from 5.4°±1.8°,8.2°± 2.6° before surgery to 4.0°±0.9° and 5.3°±1.3° after surgery respectively.The mean AOFAS hindfoot score before operation was 76.8±7.0 and increased to 94.1±3.3 at the last follow-up.There were ten cases receiving excellent effect,6 good and 1 moderate.The good and excellent rate was 94.1％ (16/17).All the 17 patients achieved paiu relief and none had recurrent injury till the last follow-up.Conclusion TwinFix suture anchor fixation along with overlap suturing was an effective way in dealing with old deltoid ligament injury cases.
