Arthritis in the lesser metatarsocuneiform joint can cause pain and deformity, affecting your quality of life and mobility. Lesser metatarsocuneiform joint fusion surgery is a procedure designed to address these issues, providing long-term relief and improved foot function. This guide provides a comprehensive overview of the surgery, its benefits, and the recovery process.
What is Lesser Metatarsocuneiform Joint Fusion Surgery?
This procedure is aimed at reducing pain and correcting deformity in the lesser metatarsocuneiform joint, located in the middle of the foot. During the operation, the worn-out cartilage is removed, and the raw bone surfaces are fused together to stabilise the joint. In some cases, a bone graft may be used to facilitate healing and improve alignment.
Internal fixation, such as screws, plates, or wires, is used to secure the bones in place while they heal. These fixation devices typically do not need to be removed unless complications arise. The surgery usually takes about 60 minutes.
Why Consider This Surgery?
The main goals of this procedure are:
To alleviate pain caused by arthritis or instability in the midfoot.
To improve foot alignment and prevent further deformity.
Advantages:
Reduces pain and deformity effectively.
Risks and Considerations
While the surgery is generally successful, there are specific risks to be aware of, including:
Pain from the graft site (if used).
Arthritis developing in other joints.
Transfer of pressure to the ball of the foot.
Non-union of the bone, where the bone does not heal properly.
Fixation issues with screws, plates, or pins.
Nerve irritation or damage.
Dorsal displacement of the metatarsal bone.
Your surgeon will discuss these risks with you and explain the measures taken to minimise complications.
Who is a Candidate for This Procedure?
This surgery is recommended for individuals with:
Painful, unstable, or arthritic joints in the midfoot area.
Deformities or conditions that have not responded to non-surgical treatments.
Alternative treatments may include:
Activity modifications.
Painkillers and anti-inflammatory medications.
Special footwear, such as rocker-soled shoes.
Orthotic foot supports or insoles.
Joint injection therapy.
What to Expect During Surgery
The procedure is typically performed under a local anaesthetic block, ensuring you remain awake but pain-free. Sedation or general anaesthesia may also be an option, depending on your preference and the surgeon’s recommendation. You will spend additional time in the day surgery unit before and after the operation to rest.
Recovery Timeline
First 2-4 Days:
Pain is typically most intense during this period, but prescribed painkillers will help manage it.
Rest is essential. Keep your foot elevated and non-weight-bearing.
Limit walking to essential activities, such as bathroom trips, using crutches as instructed.
One Week After Surgery:
Attend a follow-up appointment to have your foot checked and, if necessary, redressed or recast.
Two Weeks After Surgery:
Sutures will be removed, and a new cast may be applied.
6-8 Weeks After Surgery:
An X-ray will be taken to assess healing progress.
If all is well, the cast will be removed, and you will transition to a walking boot or trainer-style shoe.
8-10 Weeks After Surgery:
You can start wearing supportive lace-up shoes.
Swelling and mild discomfort may persist as you gradually increase activity levels.
Rehabilitation exercises may be introduced, or a referral to a physiotherapist provided.
You may return to non-manual work; manual jobs may require additional recovery time.
Driving can resume if you can safely perform an emergency stop (check with your insurer).
12-16 Weeks After Surgery:
The foot should feel more normal, with reduced swelling.
Sporting activities may be considered depending on your progress.
Six Months After Surgery:
A follow-up review will evaluate your recovery.
Swelling should be minimal, and you should experience the full benefits of the surgery.
Twelve Months After Surgery:
Full healing is achieved, and improvements stabilise.
Planning for Recovery
To ensure a smooth recovery:
Arrange for assistance with daily tasks during the non-weight-bearing phase.
Follow all post-operative care instructions provided by your surgeon.
Attend all scheduled follow-ups to monitor progress.
Lesser metatarsocuneiform joint fusion is a reliable procedure for reducing pain and correcting deformity in the midfoot. With proper preparation and adherence to recovery protocols, patients can achieve significant improvements in mobility and quality of life. If you’re considering this surgery, consult your healthcare provider to determine if it’s the right option for you.
