Brachymetatarsia surgery is typically performed using one of two methods:
Bone Grafting
The first is a single-stage lengthening procedure, where the bone is cut and lengthened using a bone graft—either from the patient, a bone bank, or an artificial source. Specially designed screws and plates stabilize the bone and graft until healing occurs.
External Fixator Use
The second approach involves an external fixator. This device, secured with specialized wires, allows for gradual bone lengthening over several weeks. The fixation remains in place until X-rays confirm complete bone healing.
Procedure:
Preoperative Preparations: The patient is typically administered general anesthesia in most of the extensive cases. The surgical site is cleaned and sterilized to prevent infection.
Incision: A small incision is made on the affected toe or foot to access the joint and the bone.
Realignment and Closure: After resection, the remaining bone is repositioned to ensure proper alignment. If necessary, the bones may be stabilized with pins or screws. The incision is then closed with sutures, and a bandage is applied to protect the site.
Postoperative Care: The patient is advised to keep weight off the foot during the initial healing period to ensure the bone heals properly. Depending on the complexity of the procedure, a post-operative shoe or splint may be used to keep the foot in a favorable position for healing. Follow-up visits are scheduled to monitor the healing process and check for complications such as infection or misalignment.
Bone Healing: The bones at the joint are carefully aligned so they can heal together. In some cases, the bones may be fixed using internal hardware such as pins, plates, or screws to ensure proper positioning during the healing process.
Closure and Bandaging: Once the joint is removed and the bones are aligned, the incision is closed with sutures. A sterile dressing or bandage is applied to the site.
Postoperative Care: Similar to bone resection, the patient is advised to avoid putting weight on the foot for an extended period, typically several weeks. The surgeon may prescribe pain management options and advise the patient to follow up for regular check-ups to ensure the bones are healing correctly. In some cases, physical therapy may be recommended to help improve mobility and strength once healing has progressed.
The procedure generally takes around three hours, and after the excess bone and tissue are removed, the incision is closed with stitches. The surgery is minimally invasive, ensuring a faster recovery time and reduced risk of complications.
