PERITROCHANTERIC FEMUR FRACTURES OF OLDEST ELDERLY. LONG-TERM FOLLOW UP STUDY OF 455 PATIENTS.

Abstract

PURPOSE: Oldest elderly trochanteric fractures treatments are common but long term follow up studies are indistinct. Previous data about all outcomes are not reported for oldest one. The purpose was to update all the results for these oldest old patients.

METHODS: A prospective, longitudinal study was undertaken of 455 “31 A1, A2, A3” (OTA) peritrochanteric femur fractures through 2002. There were 84% female patients. The age was 88 (80–105) ±5 years. Associated hip arthritis rate was 10%. 31 A1 and 31 A2 really trochanteric fractures were 90% (31 A1: 52% and 31 A2: 38%), 31 A3 subtrochanteric were 10%. Surgical treatment was achieved for 97%: [extramedullary internal fixation (dynamic hip screw): 36%, intramedullary (trochanteric nail): 56%, hip arthroplasty: 5%]. Functional treatment (not displaced or contra-indicated) was achieved for 3%. Katz, mental, Parker, walking scores, live place before and at long term after fracture, radiological healing and complications were registered.

RESULTS: The radiological healing rate after 3 months was 85% and after 6 was 97%. Complications rate: the general complications rate during 1st month was 12% and between 1st and 3rd month was 8%. The local complications rate during the 1st month was 4% (local infection: 1%) and between 1st and 3rd month was < 1%. The new surgical procedures rate during the 1st month was < 0.5%, between 1st and 3rd month was 3%, between 3rd and 6th month was 3%. Clinical results: Post-operative weight bearing was uncertain. 6th month after fracture 72% of the patients were alive (dead: 28% and non-surgically treated: twice more). All scores and live place demonstrated dependence increase. > 6th month after fracture mortality was common.

CONCLUSION AND SIGNIFICANCE: Intra/extra capsular hip fractures ratio increases after 80. These are older, more dependant and help demanding. Hip arthritis inflates hip fracture risk. Success points technical procedures had been demonstrated by randomised studies: dynamic hip screws for stable fractures and trochanteric nails for unstable; hip prosthesis for arthritis or poor bone. Practice surgery for all trochanteric fractures. Don’t separate trochanteric/subtrochanteric. The prognostic is rather poor (mortality rate, functional outcomes), depending on initial functional score and dependence. Modern internal fixation is reliable. Arthroplasty should be considered.
