HEMIARTHROPLASTY WITH STRAIGHT STEM ENDOPROSTHESIS IN OVER 70 YEARS OLD PATIENTS WHO HAVE FEMORAL NECK FRACTURES

Between January 1996-January 1998, Department of Orthopaedics and Traumatology of PTT Training Hospital, hemiarthroplasties with Protek's Protema-90 straight stem endoprosthesis were performed in over 70 years old 27 patients who have femoral neck fractures. 21 of them were taken place in the study and mean follow up is 15.1 (ranging between 12-32) months. Of these, 14 were female and 7 were male. Mean age of the cases is 79.6 (72 86). According to Harris Hip Scoring System we obtained excellent, good results in 17 patients (%80) and fair, poor results in 4 (% 20) patients. The prostesis we used have two major advantage. First, it is not only able to be applied easily by surgeon but also patients have been provided more stability and motion by prosthesis. Second, Its price is much cheaper than total endoprosthesis and bipolar prosthesis which intend to achieve same purpose. It was concluded that hemiarthroplasty with straight stem which has moduler head were successfully applied for femoral neck fractures in over 70years old patients.

70 YAÞ ÜZERÝNDEKÝ FEMUR BOYUN KIRIKLI HASTALARDA DÜZ SAPLI (STRAIGHT STEM) PARSÝYEL PROTEZ UYGULAMASI

Ocak 1996-Ocak 1998 yýllarý arasýnda PTT Eðitim Hastanesi Ortopedi ve Travmatoloji Kliniði'nde 70 yaþ üzerindeki intrakapsüler femur boyun kýrýklý 27 hastaya primer olarak Protek'in Protema 90 tipi modüler baþlý ve düz saplý (straight stem) protezle sementli hemiartroplasti ameliyatý yapýldý. En az 1 yýl süreyle takip edilen 21 hasta deðerlendirmeye alýndý. Ortalama takip süresi 15. 1 (en kýsa 12, en uzun 32) aydýr. Hastalarýmýzýn 14' ü kadýn, 7 si erkek olup ortalama yaþ 79.6 (en küçük 72- en büyük 86) yýldýr. Hastalar ameliyat sonrasý Harris'in fonksiyonel skorlama sistemine göre deðerlendirildiðinde 17(%80) hastada çok iyi ve iyi, 4(%20) hastada orta ve kötü sonuç elde edildi. Kullandýðýmýz parsiyel protezin modüler baþlý ve düz saplý olmasýnýn gerek ameliyat sýrasýnda cerraha kolaylýk saðlamasý gerekse ameliyat sonrasý hastaya daha fazla hareket ve stabilite kazandýrmasý önemli bir üstünlüðünü oluþturmaktadýr. Hastaya benzer faydayý saðlayan total protez ve bipolar protezlere göre fiyatýnýn oldukça ucuz olmasý en önemli üstünlüðüdür. Bu çalýþma da 70 yaþ üzerindeki hastalarda femur boyun kýrýklarýnýn düz saplý protezle baþarýlý olarak tedavi edildiði sonucuna varýlmýþtýr.
