PURPOSE: To compare the individual influence of different types of socket designs
on the hip's range of motion in transfemoral amputees. PATIENTS AND METHODS: We
studied the kinematic parameters of the hip joint for patients with transfemoral
amputation under four experimental conditions: without a socket, with a
quadrilateral socket, an ischial containment socket, an ischial-ramal containment
socket. An opto-electronic system was used to record the movements in the frontal
and sagittal planes for a 3D movement analysis. RESULTS: The hip's range of
motion is always significantly restricted with the sockets, regardless of their
type, compared to the situation without a socket (P<0.05). The adduction and
extension movements are the most restricted. The global amplitude (i.e., the sum
of all the ranges of motion) is significantly higher for the ischial-ramal
containment socket (139.5 degrees ) compared to the ischial containment socket
(125.4 degrees , P=0.002) and the quadrilateral socket (127.3 degrees , P=0.01).
No comparable study exists in the literature, especially for the ischial-ramal
containment socket. CONCLUSION: The ischial-ramal containment socket seems to be
the most interesting type of socket in terms of the criterion studied. It still
remains to identify the possible functional improvements that this design would
provoke during gait and during daily activities.
