In AICBG, what type of disturbance may occur related to the tensor fascia lata?

In the context of Anterior Iliac Crest Bone Grafting (AICBG), a gait disturbance can occur related to the tensor fascia lata due to its functional role in stabilizing the hip and aiding in the movements of the leg. The tensor fascia lata helps to maintain the tension of the iliotibial band and plays an important part in hip abduction and medial rotation.

When bone grafting is performed from the anterior iliac crest, this procedure often involves harvesting bone from an area close to where the tensor fascia lata muscle is anchored. Disruption to this muscle or its surrounding structures during the grafting procedure can lead to altered biomechanics and compensatory movements, which may manifest as a gait disturbance.

The other options, while they may relate to certain musculoskeletal conditions, would not be primary concerns directly arising from the harvesting procedure of the anterior iliac crest in relation to the tensor fascia lata. Thus, understanding the functional implications of the tensor fascia lata in the context of AICBG solidifies the significance of gait disturbance as the correct response.
