Abstract
|
|
|
The purposes of this study are to document the effect of the undisplaced intra-operative fracture of the calcar area during primary cementless total hip arthroplasty and to compare the clinical result of primary cementless total hip arthroplasty
in
patients who sustained an intraoperative fracture of the calcar area with an unfractured control group. Twenty-two patients of intraoperative undisplaced fracture of calcar area during cementless total hip arthroplasty matched by age, sex,
diagnosis,
type of the prosthesis, and length of follow-up were compared with 22 patients who had cemetless total hip arthroplasty without fracture. The fractutes were managed with the application of one or two cerclage wires with stability test. No
statistically
significant difference was found in clinical or radiographic results after cemenatless total hip arthroplasty between the calcar fracture group and control group. If initial stability of the implant is satisfactory, despite of intraoperaive
fracture
good clinical results can be expected with cementless total hip arthroplasty. The subsidence of femoral stem and the unstable fixation/stability were noted in three hips of which the diagnosis was Stage IIIC or IV avascular necrosis of femoral
head.
