Brief Summary

Shortening of the abductor lever arm is a particular concern with the SHS, and the resultant biomechanical alterations may impair gait, including decreased cadence, gait speed and increased double support time on the injured side.

The use of an IM nail device may reduce shortening and improve functional parameters in this patient cohort

Detailed Description

Published work in this field to date has not demonstrated an advantage of nailing over hip screw in intertrochanteric proximal femoral fractures. The current literature focus on outcome questionnaires, pain scores and basic functional tests alone may not delineate all functional benefits. A key factor in whether a person, post hip fracture, returns to independent living is gait speed. The cost implications on the healthcare provider of having 30% of this ever increasing group losing their independence and requiring admission to a care facility post hip fracture is a growing problem.

Shortening of the abductor lever arm is a particular concern with the SHS, and the resultant biomechanical alterations may impair gait, including decreased cadence and increased double support time on the injured side.

The cost differential between a nail and a SHS is a barrier to routine use of nailing in this population unless a clear benefit is demonstrated. Fracture nonunion is uncommon in this injury however improving functional outcome and reducing morbidity and mortality in this group is important.

In this prospective randomised study, the investigators examine whether an intramedullary nail (TFNA) results in a greater functional benefit in A1/A2 intertrochanteric fractures compared with the SHS, in terms of gait speed and other objective gait assessments, as well as other established post operative outcome measures.
