OBJECTIVES: The effect of implant removal after internal fixation of a @entity2249 on physical functioning was analyzed. Characteristics of @entity1 who had their implant removed were studied, as it is currently unknown from which type of @entity1 implants are removed and what effect removal has on function. DESIGN: Secondary cohort study alongside a randomized controlled trial. SETTING: Multicenter study in 14 hospitals. @entity1 AND INTERVENTION: @entity1 who had their implant removed after internal fixation of a @entity2249 are compared with @entity1 who did not. MAIN OUTCOME MEASUREMENTS: @entity1 characteristics and quality of life (Short Form 12, Western Ontario @entity571 Index) were compared. Matched pairs were selected based on @entity1 / @entity174 characteristics and prefracture physical functioning. RESULTS: Of 162 @entity1 , 37 (23%) had their implant removed. These @entity1 were younger (median age: 67 vs. 72 years, P = 0.024) and more often independently ambulatory prefracture (100% vs. 84%, P = 0.008) than @entity1 who did not. They more often had evident implant back-out on x-rays (54% vs. 34%, P = 0.035), possibly related to a higher rate of Pauwels 3 @entity174 (41% vs. 22%, P = 0.032). In time, quality of life improved more in implant removal @entity1 [+2 vs. -4 points, Short Form 12 (physical component), P = 0.024; +9 vs. 0 points, Western Ontario @entity571 Index, P = 0.019]. CONCLUSIONS: Implant removal after internal fixation of a @entity2249 positively influenced quality of life. Implant removal @entity1 were younger and more often independently ambulatory prefracture, more often had a Pauwels 3 @entity174 , and an evident implant back-out. Implant removal should be considered liberally for these @entity1 if @entity158 persists or functional recovery is unsatisfactory. LEVEL OF EVIDENCE: Therapeutic Level II.
