TREATMENT OF DISPLACED SUBCAPITAL FEMORAL FRACTURES WITH THA – TRAUMA AND REHABILITATION



Abstract

Aim:Evaluate the results of primary cemented/cementless THA for the treatment of displaced femoral neck fractures.

Material-Method:121 pts with femoral neck fractures underwent THA 2.1 days on average after their admission.The mean follow up period 4.1 y.112 pts had Garden III-IV fractures,9 pts had Garden II fractures.A cementless THA was applied in 75 pts (Group A,average age 61.4 y),46 pts were treated with cemented THA (Group B,72.4 y).Last follow up evaluation with Harris Hip Score (HHS) and radiological assessment with the Engh/Wixon scores was available in 92 pts.In 25 elderly pts a cementless THA was applied due to established impairment of their cardiopulmonary status.

Results:The mean HHS was 82,3.Radiological score for the cementless THA:+5,8 for the cup and +6,4 for the stem according to Engh scale (satisfactory integration for the prosthesis Perfecta,Synergy) and a 74,8% liability of integration according to Wixon scale (Spotorno).Complications:Early dislocation 3,loosening 5,heterotopic ossification 8,periprosthetic fracture 1,femoral nerve paresis 1,wound infection 1.No systematic complications were noted in the elderly patients with cardiopulmonary disorders,possible due to selection of a cementless THA.

Conclusions:THA (cemented/cementless) for the treatment of displaced femoral neck fractures give very good midterm results.Cementless THA is probably the choice of treatment in elderly pts with cardiopulmonary disorders.
