Anchors for the treatment of ankle fracture combined with deltoid ligament injury / 中国组织工程研究

ABSTRACT

BACKGROUND:Ankle fracture combined with deltoid ligament injury can disorders the anatomical structure of ankle joint. Improper treatment can cause more serious complication, such as walking disorders. OBJECTIVE:To evaluate the clinical effect of anchor repair plus open reduction internal fixation in the treatment of ankle fracture combined with deltoid ligament injury. METHODS:Thirty-five patients with ankle fracture combined with deltoid ligament injury were selected from the Department of Orthopedics, the Sixth People’s Hospital Affiliated to Shanghai Jiao Tong University between May 2009 and January 2011, including 24 males and 11 females, and al the patients were treated with anchor repair plus open reduction internal fixation. The age of the patients was 22-61 years, averaged 35.7 years, and al the patients were closed injury without other fractures. The treatment time was 2-10 days, average 4.6 days. According to Lauge-Hansen classification, 26 patients had supination-eversion ankle fracture and nine patients had pronation-eversion. According to Danis-Weber classification, 26 patients were C type and nine patients were B type. After al the three patients were treated with anchor repair, the treatment effect of anchor repair was evaluated through assessing the improvement of clinical symptoms and signs, as wel as the imaging examination of repair and healing. RESULTS AND CONCLUSION:Al the 35 patients were fol owed-up for 9-26 months, average 13.8 months. Al the patients got Ⅰ stage healing without complications of infection and screw loosening. Fol ow-up X-ray film showed al the 35 patients with ankle fracture achieved bone union, the healing time was 10-21 weeks, average 13.6 weeks. Modified Baird-Jackson score system showed excel ent in 11 cases, good in nine cases, average in four cases, poor in one case, and the excel ent and good rate was 85.7%. At 6 months after internal fixation, the stress X-ray film examination showed the mal eolus gap of the affect side was (3.49±0.36) mm, the mal eolus gap of the healthy side was (3.37±0.41) mm, and there was no significant difference (P>0.05). The results indicate anchor in the repair of deltoid ligament injury during the treatment of ankle fracture with open reduction internal fixation can achieve satisfactory therapeutic effect.
