Interphalangeal Collateral Ligament Repair

The interphalangeal joint is a sacral joint composed of the middle and proximal phalanges and the distal and middle phalanx bones, and can only perform flexion and extension activities. The collateral collateral ligament and the ulnar collateral ligament on both sides of the joint strengthen the joint capsule. The collateral ligament injury is mostly caused by the lateral stress of the finger, and the temporal side is more than the ulnar side. The effect of non-surgical treatment is not certain, and the result often results in a loose collateral ligament and an unstable joint. Therefore, once the lateral instability of the joint occurs after the injury, there is an indication for surgical repair. Treating diseases: joint sprains Indication Applicable to the left middle finger sprain, proximal interphalangeal joint tumor. The ulnar bias shows that the joint between the fingers is unstable. Contraindications 1. The infection after the local injury has not been eliminated. 2. Injury refers to the passive flexion and extension of each joint. 3. Fresh incomplete lateral collateral ligament injury. 4. Patients with systemic diseases who cannot tolerate surgery. 5. Local infections, not suitable for surgery. Surgical procedure 1. Anesthesia: According to the needs of surgery, choose the appropriate anesthesia. 2. Position: According to the needs of surgery, choose the appropriate position. 3. Incision Select the appropriate incision according to the needs of the operation. 4. Surgical operation (1) Normally, a vertical incision is made on the side of the interphalangeal joint. (2) Incision of the skin and subcutaneous tissue, cutting of the transverse fibers, revealing the deep collateral ligament and identifying the fracture site. (3) Check for small bone fragments or ligament fragments in the joint. (4) If it is a fresh injury, it can be sutured directly after cleaning the broken end. In the case of old injuries, there is often a scar connection between the ends, a tongue flap is made on the scar tissue, and then an overlapping suture is performed. (5) After suturing, the interphalangeal joint was fixed with a finger rest, and the exercise was started after 3 weeks.
