Short-term results of hip endoprosthesis with hemiprosthesis after femoral neck fracture, maintaining joint lubrication in adult patients

Nikolay Kolarov, Ruslan Popstefanov


INTRODUCTION: Femoral neck fracture is one of the most common traumas in adult patients. Patients with such fractures usually have many accompanying diseases - polymorbidity. The majority of intraartic­ular femoral neck fractures are indicated for primary hip joint alloplastic surgery. Nowadays, hip hemiar­throplasty is a routine and relatively safe procedure for the treatment of this type of trauma. Despite the higher operational risk compared to osteosynthesis, this procedure is preferred for the treatment of femoral neck fractures in patients over 75 years of age.

AIM: The main aim of this study is to build up optimal indications or guidelines for primary endoprosthe­sis with hemiprosthesis after femoral neck fractures and to justify the choice of an optimal hip hemipros­thetic implant. The design of the hemiprosthesis should be capable of minimizing the risk of acetabular pro­trusion for a long time after the surgical procedure.

MATERIALS AND METHODS: A one-year study assessed the therapeutic effectiveness of the ellipti­cal monoarticular endoprosthetic head use compared to monoarticular spherical and biarticular endopros­thetic heads use based on three groups of criteria: subjective, radiographic and functional criteria. Better therapeutic outcomes, according the criteria above, have been achieved with the use of the elliptical mono­articular endoprosthetic head.
