Abstract

Aim of this study was to recognize differences in long-term clinical outcome after femoral neck fracture and hip endoprosthesis implantation. Total of 145 patients were examined, 32 patients with unipolar, 70 with bipolar and 43 patients with total hip endoprosthesis. The mean values of Harris hip score, after 3.8 ± 1.9 years, were: 72.1 ± 17.8, 74.27 ± 19.1, 78.2 ± 22.5 for patients with unipolar, bipolar and total hip endoprosthesis, respectively. No statistically significant difference was observed (p=0.704). The in-hospital mortality rates were: 4.3%, 4.6%, and 5.3% for groups of patients with bipolar, unipolar and total hip endoprosthesis, respectively. Considering clinical outcomes, general health and costs, it could be concluded that choice of endoprosthesis does not pose an obstacle in patient’s recovery.

Highlights

Consequences of aging on the hip joint, as well as reduction of psycho-physical abilities of a patient and comorbidities predispose elderly to the hip joint fracture

Due to difficulties in treatment of the hip fracture, recovery is exhausting for patients and expensive for society

Summary

Introduction

Consequences of aging on the hip joint (osteoporosis, varisation of the femoral neck), as well as reduction of psycho-physical abilities of a patient (neuromuscular incoordination, fear from activities) and comorbidities predispose elderly to the hip joint fracture. “In vitro” experiments cannot offer absolutely accurate data, due to many complex characteristics of structures of implant, bone, cement, and some uncertain numerical parameters. This emphasizes a need for clinical studies, which could ensure more realistic data about behavior of different endoprosthetic devices “in vivo” in order to confirm present methods in treatments and point to some critical moments. There is no published study which compared long-term clinical outcome among unipolar, bipolar and total hip endoprostheses after femoral neck fracture. Aim of this study was to compare long-term clinical outcomes after implantation of three different types of hip endoprostheses after femoral neck fracture
