Flexor Tenotomy

On This Page

WHAT IS IT?

A tenotomy is a minimally invasive procedure that involves cutting or releasing a tendon that’s causing a joint to stay in a bent position. It’s most commonly used to help straighten hammertoes and clawed toes. It helps straighten the affected toe by reducing the pulling force that keeps it curled.

The procedure has an 80 to 95% success rate for improving symptoms. The rate of recurrence is lower if the deformity being treated is flexible (i.e.: the toe can be manually straightened out). You can often resume activities within a few days of the procedure – often the same day. A tenotomy can be performed on multiple toes in one appointment.

WHAT CONDITIONS DOES IT HELP?

  • Flexible hammertoes and clawed toes (where the toe can still be manually straightened)
  • Painful corns or calluses at the tip or top of the toe (caused by hammertoes and clawed toes)
  • Ulcers or pressure points, especially in patients with diabetes, caused by abnormally bent toes
  • In diabetic or neuropathic patients, the tenotomy is sometimes done prophylactically to prevent or treat plantar ulcers under the toe tips – with generally excellent results and low complication rates.

A tenotomy is considered when conservative treatments, like orthotics, padding or toe devices, do not work.

In rigid hammertoes and clawed toes (i.e.: the toe cannot be manually straightened), or if bone/joint changes are advanced, a PIP joint arthroplasty or fusion may be a better option.

HOW DOES IT WORK?

A hammertoe or clawed toe occurs when one of the smaller toes (most often the 2nd, 3rd, or 4th) bends abnormally at the middle joint due to muscle/tendon imbalance. Over time, the tendon on the underside of the toe (the flexor tendon) becomes tight and rigid, preventing the toe from lying flat.

A flexor tenotomy releases this tight tendon, allowing the toe to relax and straighten.

WHAT WILL HAPPEN?

At your first appointment, the chiropodist will perform a foot assessment with a full biomechanical and gait analysis in order to diagnose your foot condition, its underlying causes, and determine the best course of treatment, at which time the chiropodist will determine whether a flexor tenotomy is right for you.

A flexor tenotomy occurs in-clinic under local anaesthesia. First the area is cleaned and numbed. The chiropodist will then use a small blade or needle (18 Gauge Needle) to cut the flexor tendon in the bent toe. The toe is then gently extended to ensure the tendon is released and to correct the deformity. Afterwords, a dressing is applied. No stitches are usually needed.

RECOVERY & AFTERCARE

It usually takes 2-3 weeks to fully heal from the surgery – much quicker than open surgery. Following your procedure, the chiropodist will provide you with aftercare instructions for the wound. You will be able to walk normally right away – provided you wear supportive shoes. You may experience mild swelling or soreness, and temporary numbness from the local anaesthetic.

You will then come back 1 to 2 weeks after the procedure for a follow-up check-up to check the toe alignment and that the wound has healed.

RISKS, COMPLICATIONS & CONTRAINDICATIONS:

While rare, potential issues include:

  • Overcorrection (toe becomes too straight or floppy)
  • Recurrence if other tendons/muscles tighten over time
  • Minor infection or delayed healing
  • Persistent pain if joint capsule is tight or arthritic

A flexor tenotomy may be contraindicated for people with the following:

  • Active infection at or near the planned incision site
  • Osteomyelitis of the toe or underlying bone infection
  • Allergy to local anaesthetic
  • Severe peripheral artery disease or critical limb ischemia
  • Uncontrolled diabetes
  • Uncontrolled bleeding disorders
  • Immunosuppression or disorders that affect the body’s ability to heal (i.e.: diabetes, steroids, chemotherapy, etc.)
  • Fixed bony deformities (these are unlikely to benefit from the procedure)
