What Is A Lapidus Arthrodesis for Bunions?

Lapidus arthrodesis is a surgical procedure used to correct severe or recurrent bunions (hallux valgus deformity) that do not respond to conservative treatments. A bunion is a bony bump that forms at the base of the big toe, causing it to deviate toward the other toes. It is often associated with the misalignment of the metatarsophalangeal (MTP) joint, the joint connecting the metatarsal bone (foot bone) to the proximal phalanx bone (toe bone).

The Lapidus arthrodesis procedure involves fusing the first metatarsal bone with the medial cuneiform bone, which is located in the middle of the foot. By fusing these bones, the joint is immobilized and stabilized, correcting the deformity and realigning the big toe. The goal of the surgery is to reduce pain, improve foot function, and prevent the bunion from recurring.

The procedure generally involves the following steps:

  1. Anesthesia: The patient is typically given either general anesthesia (to put them to sleep) or regional anesthesia (to numb the lower body) before the surgery.
  2. Incision: The surgeon makes an incision over the MTP joint to access the bones.
  3. Bone preparation: The cartilage is removed from the joint surfaces of the first metatarsal and the medial cuneiform bones.
  4. Bone fusion: The bones are brought into proper alignment, and screws or other fixation devices are used to secure them together, promoting bone fusion.
  5. Closure: After the fusion is complete, the incision is closed with sutures, and the surgical site is dressed and bandaged.

Post-operatively, the patient will need to use crutches or a walker for a period of non-weight-bearing on the foot to allow for proper bone healing. A cast or a specialized boot may also be used to protect the foot during the initial healing phase. Physical therapy and rehabilitation exercises are essential to regain strength and mobility in the foot during the recovery process.

Lapidus arthrodesis is a significant procedure and is generally reserved for cases of severe bunions or when other bunion correction techniques have not been successful. As with any surgical procedure, there are potential risks and complications, including infection, delayed bone healing, and non-union (failure of the bones to fuse). The decision to undergo Lapidus arthrodesis is made after a thorough evaluation and discussion with an orthopedic surgeon, who will assess the individual’s specific condition, medical history, and overall health to determine if the procedure is the appropriate treatment option.
