Hemiarthroplasty For Femoral Neck Fractures, Femoral Head Necrosis Were Retrospectively Analyzed

Objective: Follow-up 181 patients who were treated with hemiarthroplasty in our hospitalin rencent 20 years。In order to give clinical indications for the operations in femoral neckfractures and Avascular Necrosis of the Femoral Head。Methods: Follow-up our hospital 110 patients who were treated with hemiarthroplastyfrom 1985-april, 2005(time ranging over 6 years and 3 months) succefuly and count function ofpostoperative patients with postoperative times, The size of activities, types of prosthesis, typesof operation(with or without cement) with our national hip scores standard.results.(1) In all 110 cases, 43 patients had hip pain (39.4%); 3 dislocations(2.75%). Therewere 17 cases acetabular wear(15.5%), 9 cases DVT(8.20%),30 cases loosening andsubsidence(27.30%), 7 received secondary arthroplasty (revision rate6.36%).⑵.with timesgones, effect drops.(3)function of group unipolar hemiarthroplasty was not good to groupbipolar hemiarthroplasty p<0.05. (4) function of patients who obtain cemented hemiarthroplastyare more than those with uncemented hemiarthroplasty,p< 0.05.Conclusion:1.The clinical results of hemiarthroplasty for old femoral neck fracture and AvascularNecrosis of the Femoral Head patients whose body constitution was feeble. activity amount wasfew. life time was in 5 years. Acetabulum was Intact were quite dependable.2.1n clinical results, function of patients with uncemented HA are poor than that of patientswith cemented HA。function of group unipolar hemiarthroplasty was poor than that of groupbipolar hemiarthroplasty3.Long-term clinical results were worse than short-term results.4.Hemiarthroplasty is not recommdable for those comparatively younger patients withgood systematic status, which should be treated by methods other such as THR5.Strictly appraising the operative indications, standardizing the operative processes,effectively preventing out out of the postoperative complications will remarkable improve theclinical results of hemiarthroplasty for femoral neck fractures.
