Flexor Tendon Injuries: Causes, Symptoms, and Treatment
Flexor tendons are cord-like structures that connect the flexor muscles to the bones, enabling the bending or flexing of the fingers. These tendons run from the elbow and forearm, pass through the wrist, and attach to the bones of the fingers. They move through fibrous rings, known as pulleys, which guide and keep the tendons close to the bones for efficient movement of the joints.
Flexor Tendon Injuries
Deep cuts to the palm side of the wrist, hand, or fingers can damage the flexor tendons, as well as the surrounding nerves and blood vessels. While the external injury may appear minor, it can be quite complex internally. When a tendon is cut, its ends act like a rubber band, pulling apart. If a tendon is not fully severed, the finger may still bend but may cause pain, catching, or eventually tear completely. If the tendon is entirely cut, the finger joint will be unable to bend on its own.
Treating Flexor Tendon Injuries
Since the tendon ends typically separate after a cut, they will not heal properly without surgical intervention. Your doctor will guide you on the urgency of the surgery based on the severity of the injury. Various repair techniques may be used, depending on the type of tendon injury, and special attention is required to preserve the pulleys of the finger.
- Post-surgery care: After surgery, the injured area may be protected from movement or placed on a controlled limited-movement regimen for several weeks, based on the nature of the injury.
- Hand therapy: Your surgeon may recommend hand therapy after surgery to assist in recovery.
- Rehabilitation: After four to six weeks, you may begin to move your finger slowly, without resistance, to regain mobility.
It is crucial to follow your surgeon’s guidance closely to ensure the best possible recovery and preserve the functionality of your finger.
