The best time to splice a finger tendon after a rupture is within 6 hours of the injury.
After a tendon rupture, it is best to splice the tendon within 6 hours of the injury. At this time, not only is there less risk of infection, but the swelling at the site of the injury has not reached its peak and the success rate of the tendon anastomosis is higher. Splice the tendon more than 6 hours after the injury increases the risk of postoperative infection and is not conducive to suturing and tendon healing.
Tendons have the function of transmitting muscle contraction forces to the bone to produce joint flexion and extension movements. Therefore, when tendon rupture occurs due to external forces or chronic strain injury, it can seriously affect local function.
Therefore, when a tendon rupture occurs, it is important to seek prompt medical attention. If untreated, the ruptured tendon will gradually contract and adhere to the surrounding tissues, thus making surgery more difficult.
