What might excessive lordosis in a TF prosthetic indicate?

Excessive lordosis in a transfemoral (TF) prosthetic may indicate a hip flexion contracture. When a hip flexion contracture is present, it restricts the hip joint's ability to extend fully. As a result, the individual's pelvis may tilt forward excessively during standing or walking, which manifests as increased lordosis in the lumbar spine. This adaptive posture is often the body's way of compensating for the limited range of motion at the hip, leading to an exaggerated curvature of the lower back.

Identifying hip flexion contractures is critical, as they can affect overall balance, gait, and comfort for the user of the prosthetic limb. Addressing this issue often requires both physical therapy to improve hip extension range and possible adjustments to the prosthesis to accommodate the contracture or improve alignment.

The other answers pertain to different concerns. For instance, a properly shaped posterior wall and insufficient socket pre-flexion can both influence fit and comfort but do not specifically lead to excessive lordosis. Similarly, excessive knee flexion would manifest differently in posture and gait analysis, typically causing other compensatory mechanisms rather than an increase in lordosis. Hence, hip flexion contracture is the most relevant condition that could lead to this specific
