Description
Summary:The primary aim of this study was to compare osseointegration limb replacement prosthesis users to normative published Prosthetic Limb Users Survey of Mobility (PLUS-M) values for traditional socket prosthesis users. The secondary aim was to investigate whether patient factors were predictive of PLUS-M scores. Retrospective review of all patients who underwent osseointegration maintained in a prospectively maintained registry. All patients ( N = 63) were invited to complete a PLUS-M survey. Thirty patients completed the survey (15 femoral osseointegration, 15 tibial osseointegration). The osseointegration limb replacement prosthesis users cohort's composite median scores and interquartile ranges for the PLUS-M Raw Score, PLUS-M T-score, and PLUS-M percentile score were 57 (46-60), T-score 62.5 (51.275-71.4), and 89.5 (54.95-98.4). PLUS-M T-scores were higher in the osseointegration limb replacement prosthesis users compared with the age and etiology matched literature-reported outcomes in traditional socket prosthesis users for above-knee ( P = 0.027) and below-knee ( P = 0.029) amputees. Tibial osseointegration scores were slightly higher than femur osseointegration scores but did not reach statistical significance. PLUS-M raw ( P = 0.047) and PLUS-M percentile scores ( P = 0.041) were significantly improved for younger patients at the time index amputation. Regression analysis supported this finding. Osseointegration limb replacement prosthesis users demonstrate improved functional mobility outcome scores relative to traditional socket prosthesis users. PLUS-M functional scores were improved for younger patients at time of index amputation.
