Osteosynthesis of femoral neck fractures: dynamic hip screw (DHS) or mini-invasive Targon FN system?

Abstract

Objectives: to investigate the long-term outcomes of femoral neck fractures that were surgically fixed using various types of extramedullary implants in patients aged 65 years and younger. Material and methods: We analyzed the clinical results of surgical treatment of femoral neck fractures by extramedullary osteosynthesis in 94 patients aged 38 to 65 years old (71 women and 23 men). The patients were divided into 3 groups according to AO/ASIF fracture classification. We used different techniques of osteosynthesis: with DHS or with Targon FN. In all patients the mental status rate SPMSQ), osteoporosis degree (Singh index), general somatic status (WHO scale) were evaluated in the preoperative period. We also evaluated next intraoperative parameters: duration of surgery, blood loss, quality of reduction, long of incision. In a year after surgery we assessed functional results (Harris Hip Score) and analysed postoperative complications. Results: It was found the inverse correlation (r = -0,8) of total preoperative parameters (WHO scale, the Singh index and mental status SPMSQ) and postoperative functional results on Harris Hip Score. With the reliability of p
