Official Description

Correction, hammertoe (eg, interphalangeal fusion, partial or total phalangectomy)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

A hammertoe deformity is a condition characterized by a flexion deformity of the proximal interphalangeal (PIP) joint, resulting in the toe curling downward. This deformity can lead to discomfort and difficulty in wearing shoes, as well as potential complications if left untreated. The correction of a hammertoe can be achieved through surgical procedures such as interphalangeal fusion or partial or total phalangectomy. Interphalangeal fusion involves the surgical joining of the bones in the PIP joint to eliminate the deformity and restore proper alignment. Alternatively, a phalangectomy may involve the removal of part or all of the affected phalanx to correct the deformity. The procedure typically requires a dorsal incision over the affected joint, allowing access to the underlying structures. The surgical approach aims to relieve pain, improve function, and enhance the overall appearance of the toe, thereby addressing both the physical and aesthetic concerns associated with hammertoe deformities.

1. Indications

The procedure for correcting a hammertoe deformity is indicated for patients experiencing the following conditions:

  • Hammertoe Deformity A flexion deformity of the proximal interphalangeal (PIP) joint causing the toe to curl downward, leading to discomfort and difficulty in shoe fitting.
  • Pain and Discomfort Persistent pain in the affected toe, particularly during walking or when wearing shoes, which may necessitate surgical intervention.
  • Functional Impairment Limitations in toe function that affect overall mobility and quality of life, prompting the need for correction.
  • Cosmetic Concerns Aesthetic issues related to the appearance of the toe that may impact the patient's self-esteem and desire for surgical correction.

2. Procedure

The surgical procedure for correcting a hammertoe deformity involves several key steps:

  • Dorsal Incision A dorsal incision is made over the affected proximal interphalangeal (PIP) joint to provide access to the underlying structures. This incision allows the surgeon to visualize and manipulate the joint and surrounding tissues effectively.
  • Extensor Tendon Management The extensor tendon is carefully split and retracted to expose the PIP joint capsule. This step is crucial for accessing the joint and performing the necessary corrections without damaging surrounding tissues.
  • Resection of Bone Wedge-shaped pieces of bone are resected from the base of the middle phalanx and the head of the proximal phalanx. This resection is aimed at correcting the alignment of the toe and facilitating the fusion of the joint.
  • Phalanx Removal Alternatively, the entire middle or proximal phalanx may be removed if deemed necessary for effective correction of the deformity. This step is determined based on the severity of the hammertoe and the surgeon's assessment.
  • Insertion of K-wire or Absorbable Wire A K-wire or absorbable wire is inserted through the middle and proximal phalanges to maintain proper alignment and promote fusion of the joint. This stabilization is essential for ensuring successful healing and restoration of function.
  • Suture Repair Finally, the dorsal incisions in the PIP joint capsule and skin are meticulously sutured to close the surgical site. Proper closure is important for minimizing complications and promoting optimal recovery.

3. Post-Procedure

Post-procedure care following the correction of a hammertoe deformity typically includes monitoring for signs of infection, managing pain, and ensuring proper healing of the surgical site. Patients may be advised to keep the foot elevated and to avoid putting weight on the affected toe for a specified period. Follow-up appointments are essential to assess the healing process and to remove any sutures if non-absorbable materials were used. Rehabilitation exercises may be recommended to restore mobility and strength in the toe as healing progresses. Patients should also be educated on proper footwear choices to prevent recurrence of the deformity and to support overall foot health.
