New approaches to osteosynthesis of ankle fractures

The results of treatment of 71 patients with ankle fractures are presented. The comparison group consisted of 32 patients whose operations were performed after edema reduction according to the AO / ASIF technique. Thirty-nine patients of the main group were operated according to our minimally invasive technique using Vshaped pins and a pin with a thread the day after hospitalization, regardless of the presence of edema in the ankle joint. All patients were operated on within 1 to 3 weeks from the moment of injury. The period of inpatient treatment of patients in the comparison group averaged 16 days, the main group-10 days, the restoration period of ankle function-6 and 2 weeks, respectively. Complications were diagnosed only in the comparison group: marginal skin necrosis in 14 (22.5%) operated, inflammatory complications in 6 (9%), metal fixation migration in 1 (1.6%), fracture failure in 4 (6.4%). The results were evaluated using the AOFAS AnkleHindfoot scale. The average score in the main group was 90.3, in the comparison group-88.6. In the experimental part of the study, the strength (tensile and shear loads) of three types of osteosynthesis of internal ankle fractures was compared: using two cannulated screws, a V-shaped pin, and two biodegradable screws made of glycosylated lactic acid. Despite the fact that the osteosynthesis of the inner ankle, the Vshaped pin was the least durable, it met all the requirements for submersible osteosynthesis. © 2020, Advanced Scientific Research.
