TOTAL HIP ARTHROPLASTY USING FITMORE® STEM IN TREATMENT OF HIP OSTEOARTHRITIS - A 3-YEAR FOLLOW-UP.

Hip osteoarthritis is a chronic degenerative disease which usually presents after the age of 50. In advanced stages of the disease, the method of choice in treating hip osteoarthritis is total hip arthroplasty. Fitmore® hip stem belongs to short-stems which preserve bone mass in the region of the greater trochanter and the distal part of the femur. In this paper we present the results of total hip arthroplasty using Fitmore® stem in hip osteoarthritis treatment. We report a series of 10 patients with osteoarthritis of hip that were treated by total cementless hip endoprosthesis with Fitmore® Hip Stem at the Clinic of Orthopedics and Traumatology, Clinical Center Niš. The average age of patients was 56 (48-65) years. There were 5 women and 5 men. The patients were followed for 3 years postoperatively and the functional outcome was assessed according to Harris Hip Score. Radiographic analysis was performed on the radiograph of the hip joint in anterior-posterior projection. In 7 patients we had excellent (over 90 points) and in 3 patients we had good (over 80 points) functional outcome according to the Harris Hip Score. After 3 years, all patients' radiological findings showed good integration of the Fitmore® stem. Four patients had cortical hypertrophy of the femur. In patients with hypertrophy of cortex, there were no clinical manifestations. Implantation of total cementless hip joint endoprosthesis with Fitmore® stem in the treatment of hip osteoarthritis is a good choice when treating younger patients with good bone quality.

Osteoartroza kuka je hronična degenerativna bolest, koja se uobičajno manifestuje posle 50. godina života. Totalna zamena kuka endoprotezom u odmaklim stadijumima bolesti je metoda izbora lečenja. Fitmore® stem pripada grupi kratkog stema, koji štedi koštanu masu u regionu velikog trohantera i u distalnom delu femura. U radu prikazujemo rezultate lečenja osteoartroze kuka implantacijom bescementne endoproteze kuka Fitmore® stemom. Prikazujemo seriju od 10 bolesnika sa osteoartrozom kuka kojima je ugrađena bescementna endoproteza kuka Fitmore® stemom na Klinici za ortopediju i traumatologiju, KC Niš. Prosečna starost bolesnika iznoslia je 54,5 (48 - 65) godina. Bilo je 5 žena i 5 muškaraca. Bolesnici su praćeni 3 godine, postoperativno. Funkcionalni rezultat procenjivan je po Harris Hip Score-u. Analizirana je rendgenografija kuka u AP projekciji. Kod 7 bolesnika imali smo odličan, a kod 3 dobar funkcionalni rezultat po Harris Hip Score-u. Kod svih bolesnika, radiološki nalaz posle 3 godine pokazuje dobro urastanje Fitmore® stema. Kod 4 bolesnika, nakon analize radiološkog nalaza primećuje se hipertrofija korteksa femura. Kod bolesnika sa hipertrofijom korteksa, nije bilo kliničkih manifestacija. Implantacija totalne bescementne endoproteze zgloba kuka Fitmore® stemom u lečenju osteoartroze kuka, dobar je izbor u lečenju mlađih bolesnika sa dobrim kvalitetom koštanog tkiva.
