Functional Outcome of Cemented Versus Uncemented Hemiarthroplasty for Intracapsular Hip Fractures

Abstract

Objectives: To determine the functional outcome of cemented versus uncementedhemiarthroplasty in displaced 
intracapsular fractures of the hip. 
Study Design: Randomized control trial. 
Place and Duration of Study:This study was carried out at the Orthopaedics Department, Shaikh Zayed Hospital 
Lahore and Ibn e Siena Hospital & Research Institute Multan from August 2010 to August 2013. 
Materials and Methods: 110 patients with hip fractures fulfilling the criteria were included,55 patients in each 
group were randomized. Patients in group A were having cemented hemiarthroplasty and in group B were having 
uncementedhemiarthroplasty respectively. After surgery all patients were mobilized as soon as they were able. All 
patients were reviewed at 12 weeks follow up using a pain scale of one to six and a mobility scale of zero to nine. 
Results: In group A, the preoperative mean pain score was 5.91±0.29 and postoperative mean residual pain score at 
12 weeks was 2.73±0.45. In group B, the preoperative mean pain score was 5.91±0.29 and postoperative mean 
residual pain score at 12 weeks was 3.00±0.64. P value 0f 0.000 was significant in the favor of cemented 
hemiarthroplasty. 
In group A, the preoperative (before fracture) mean mobility score was 7.20±0.75 and postoperative mean reduction 
in mobility score at 12 weeks was 2.80±0.76. In group B, the preoperative (before fracture) mean mobility score was 
7.20±0.75 and postoperative mean reduction in mobility score at 12 weeks was 3.20±0.76. P value 0f 0.000 was 
significant in the favor of cemented hemiarthroplasty. 
Conclusion: The use of cemented hemiarthroplasty lead to less pain in the hip and improved return of mobility as 
compared to an uncemented prosthesis.
