Socket versus bone-anchored trans-femoral prostheses: hip range of motion and sitting comfort

• This is the first study to report on hip range of motion (ROM) among active prosthesis users, when wearing and not wearing a trans-femoral socket prosthesis and to compare with individuals rehabilitated with an osseointegrated bone-anchored prosthesis. In addition, discomfort when sitting with the prosthesis is reported in both groups. The study group all had a non-vascular amputation and were divided into those supplied with a socket prosthesis (S group) (n = 43, mean age 51 years, 74% men) or a bone-anchored prosthesis (OI group) (n = 20, mean age 46 years, 75% men). Active hip ROM was measured with a goniometer, and self-reported problems with discomfort when sitting were recorded. The hip motion decreased in all directions when wearing the socket prosthesis compared to without it (P < 0.001 for all directions), and 37% of the subjects had less than 90 degrees of hip flexion when wearing their prosthesis. Discomfort when sitting was reported among 44% (n = 19) in the S group and was more common among individuals with less than 90 degrees of hip flexion motion (P= 0.025). In the OI group, no restriction in hip motion was measured with the prosthesis, and no subject had less than 90 degrees of flexion and 5% (n = 1) reported discomfort when sitting. This study shows that a trans-femoral prosthetic socket significantly reduces the ROM of the hip and that discomfort when sitting is common among individuals wearing such prostheses. Further, the study confirms that individuals using a bone-anchored prosthesis have no restricted hip motion with the prosthesis and report very few problems with discomfort when sitting.
