In Jones tenosuspension, which additional procedure is commonly required?

• A. Fusion of IPJ
• B. Fusion of MTP joint
• C. Tendon transfer of FDL
• D. Lateral ligament release

Answer: (A)

The main idea is that Jones tenosuspension changes the dynamics of the toe by suspending it with a tendon, which can leave the interphalangeal joint unstable or prone to deforming if left mobile. Adding fusion of the interphalangeal joint provides a solid, permanent correction at the joint itself, preventing recurrent flexion or instability and allowing the tendon suspension to function without causing painful motion or deformity. This adjunct stabilizes the toe in the new alignment and tends to give a more durable result, especially in patients with degenerative changes or when precise alignment is difficult to maintain with soft-tissue correction alone. The other options involve joints or procedures not routinely required with this technique, or address different goals in foot surgery.
