What is First MTP Joint Resection Arthroplasty?
First MTP (metatarsophalangeal) joint resection arthroplasty is a surgical procedure that removes part of the bone from the base of the big toe to alleviate pain and improve mobility. Unlike joint replacement, this technique does not use implants. Instead, it creates a gap between the bones to reduce friction and allow for a flexible, though not rigidly stable, joint.
When is First MTP Joint Resection Arthroplasty Recommended?
This procedure is generally recommended when joint preservation or replacement is not feasible. It may be considered in the following cases:
- Severe hallux rigidus (arthritis of the big toe)
- Failed previous surgeries, such as joint replacement or fusion
- Low-demand or elderly patients seeking pain relief over joint stability
- Patients who are not ideal candidates for fusion due to poor bone quality or medical conditions
- Rheumatoid arthritis or other inflammatory joint disease causing joint destruction
How is First MTP Joint Resection Arthroplasty Performed?
The surgery is done under regional or general anesthesia. The surgeon makes an incision over the big toe and removes the arthritic or damaged bone from the base of the toe and sometimes the metatarsal head. In some cases, a soft tissue spacer, tendon, or implant may be placed between the cut bone surfaces to prevent bone-on-bone contact. The wound is then closed and bandaged. The goal is to reduce pain and maintain some motion at the joint.
What to Expect During Recovery After First MTP Joint Resection Arthroplasty?
Postoperative recovery typically includes the use of a surgical shoe for 4 to 6 weeks to protect the toe and allow healing. Limited weightbearing may be allowed soon after surgery, depending on your surgeon’s instructions. Most patients gradually return to comfortable footwear within 6 to 8 weeks. Physical therapy may be recommended to improve strength and mobility. Some stiffness or mild instability may persist long-term.
What are the Risks of First MTP Joint Resection Arthroplasty?
As with any surgery, risks include:
- Infection
- Persistent pain
- Instability of the big toe
- Toe shortening or deformity
- Limited strength for push-off while walking
- Need for additional surgery if symptoms recur
What are the Benefits of First MTP Joint Resection Arthroplasty?
This procedure offers meaningful benefits for select patients:
- Relief from arthritis-related pain
- Preservation of some toe movement
- Avoidance of fusion or implants
- Quick recovery and return to daily activities
- Improved footwear comfort and walking function
Resection arthroplasty can be a good option for patients seeking pain relief without rigid joint fusion.
