Early clinical results of cementless,bipolar hemiarthroplasty in intracapsular femur neck fractures [Kapsül içi femur boynu kiriklarinda çimentosuz,bipolar hemiartroplastinin erken klinik sonuçlari]

Objectives: in this study we report our initial experience with the use of cementless,bipolar hemiarthroplasty in elderly patients with intracapsular femur neck fractures. patients and methods: we operated 67 consecutive patients (39 females,28 males; mean age 74.4±11.0 years; range 41 to 99 years) who admitted to our clinic june 2007 and november 2009,due to intracapsular femur neck fracture and implanted cementless,rectangular,dual-taper,straight femoral stem (zweymüller stem) with bipolar head prosthesis. all patients were allowed to full weight bearing with a walker within the first postoperative 48 hours. results: according to the garden's classification,there were nine type ii,53 type iii and five type iv fractures. twelve patients were lost to follow-up and 21 deceased during the postoperative follow-up period. among 34 patients with complete follow-up,30 were evaluated for the clinical outcome. the mean follow-up time and harris hip score of the evaluated patients were 19.4 months and 79.4 points,respectively. it was seen that,the patient age significantly correlated with the clinical outcome and a better mean hip score was obtained in the 70 years and younger age group (83.6 points) as compared to the older than 70 years age group (75.6 points) (p=0.014). mortality rate was found to be higher in patients older than 70 years (47% vs. 18%; p=0.036) and with displaced fractures (45% vs. 0%; p=0.018). conclusion: zweymüller cementless bipolar hemiarthroplasty may be an alternative treatment method for intracapsular femur neck fractures especially in the patients under the age of 70 years.
