Opening Wedge Proximal Metatarsal Osteotomy
What is Opening Wedge Proximal Metatarsal Osteotomy?
Opening wedge proximal metatarsal osteotomy is a surgical procedure performed to correct certain conditions affecting the forefoot, specifically the metatarsal bones. This procedure involves making a controlled cut in the bone and using a bone wedge to reposition and realign the metatarsal bone. It is performed to correct deformities, such as bunions (hallux valgus) or other conditions that cause instability or pain in the forefoot.
Why is Opening Wedge Proximal Metatarsal Osteotomy Performed?
Opening wedge proximal metatarsal osteotomy is typically recommended for patients with the following conditions:
Hallux Valgus (Bunion): A bunion is a bony bump that forms at the base of the big toe, causing it to deviate towards the other toes. This condition can cause pain, difficulty with shoe-wearing, and foot deformity. Opening wedge proximal metatarsal osteotomy can correct the alignment of the metatarsal bone and realign the big toe, alleviating pain and improving foot function.
Metatarsalgia: Metatarsalgia refers to pain and inflammation in the ball of the foot. It is often caused by abnormal weight distribution or pressure on the metatarsal bones. Opening wedge proximal metatarsal osteotomy can help redistribute the weight-bearing forces and relieve pain in the affected area.
How is Opening Wedge Proximal Metatarsal Osteotomy Performed?
Opening wedge proximal metatarsal osteotomy is typically performed under regional anesthesia or general anesthesia. The specific surgical technique may vary based on the extent and location of the condition, as well as the surgeon's preference. However, the general steps involved in this procedure are as follows:
Incision: The surgeon will make an incision over the affected metatarsal bone to access the bone and underlying structures.
Bone Preparation: A controlled cut is made in the metatarsal bone, allowing for repositioning and realignment. The surgeon will carefully remove a bone wedge from the cut site.
Realignment and Fixation: The metatarsal bone is repositioned to the desired alignment using the bone wedge or other implants. The bone is held in place using screws, plates, or other fixation devices to promote proper healing.
Closure: The incision is closed using sutures or surgical staples, and a sterile dressing is applied.
What can I expect after Opening Wedge Proximal Metatarsal Osteotomy?
After the surgery, you will likely need to wear a special shoe or boot to protect the foot and assist with proper healing. Your surgeon will provide specific guidelines regarding weight-bearing restrictions, post-operative care, and follow-up appointments.
Rehabilitation and physical therapy may be recommended to aid in the recovery process. This may include exercises to improve strength, range of motion, and walking mechanics. It is important to follow your surgeon's instructions regarding weight-bearing activities and rehabilitation protocols.
The recovery period can vary depending on the extent of the osteotomy and individual healing factors. It may take several weeks or months for complete healing and return to normal activities. Regular follow-up appointments will be scheduled to monitor your progress and make any necessary adjustments to your treatment plan.
Remember to report any concerns, such as excessive pain, swelling, or signs of infection, to your healthcare provider promptly.
In conclusion, opening wedge proximal metatarsal osteotomy is a surgical procedure performed to correct deformities and alleviate pain in the forefoot, such as bunions or metatarsalgia. Following your surgeon's instructions and participating in rehabilitation will help ensure the best possible.
