What is the appropriate location for flexor tenotomy in a hammer toe?

• A. DIP joint
• B. MTP joint
• C. PIP joint
• D. Talus joint

Answer: (C)

The appropriate location for flexor tenotomy in a hammer toe is the proximal interphalangeal (PIP) joint. This procedure is performed to relieve the contracture of the flexor tendon, which is responsible for the bending of the toe at the PIP joint. In a hammer toe deformity, there is often an imbalance in the muscle pull or tension on the tendons that results in the toe bending at this specific joint.

By performing a tenotomy at the PIP joint, the surgeon can effectively lengthen the flexor tendon, allowing the toe to be straightened and restoring a more functional alignment. This targeted approach helps to alleviate pain, improve comfort in footwear, and enhance the overall function of the foot.

Other choices do not represent the correct location for the procedure. For instance, performing a flexor tenotomy at the distal interphalangeal (DIP) joint would not address the primary issue at the PIP joint. The metatarsophalangeal (MTP) joint is not the site where the flexor tends to contract in hammer toe deformities. The talus joint is not applicable as it pertains to the ankle and would not be relevant to the correction of issues related to the hammer
