S66.108
Unspecified injury of flexor muscle, fascia and tendon of other finger at wrist and hand level
Clinical Classification Guidelines
Inclusion Terms
- Unspecified injury of flexor muscle, fascia and tendon of specified finger with unspecified laterality at wrist and hand level
Medical Intelligence & Overview
The ICD-10 diagnosis code S66.108 refers to an unspecified injury affecting the flexor muscles, fascia, and tendons of fingers at the wrist and hand level. This type of injury involves damage to the structures responsible for bending the fingers, which can result from various incidents such as trauma or overuse. Because the injury is unspecified, it does not pinpoint a particular finger or side (left or right), indicating the need for further medical evaluation to determine the specific details of the injury. Such injuries are common in activities involving gripping, gripping tools, or sudden impacts, and can significantly affect hand function if not properly managed.
Causes & Symptoms
Clinical Causes: Trauma from falls or accidental impacts Sports injuries involving hand contact Crushing injuries or direct blows to the hand Sudden twisting or hyperextension during activities Repetitive strain from vigorous or prolonged gripping activities
Key Symptoms: Pain, especially when trying to bend or straighten the finger Swelling around the affected finger and wrist Tenderness to touch in the affected area Limited movement or stiffness in the finger Weakness or a feeling of instability in the finger Possible bruising or discoloration A sense of catching or locking when moving the finger
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves a detailed clinical examination by a healthcare provider, who will assess finger movement, look for swelling or deformity, and check for tenderness. Imaging studies such as X-rays may be ordered to rule out fractures or dislocations, while ultrasound or MRI scans can help visualize soft tissue injuries like tears or strains in the tendons or fascia. Because the injury is classified as unspecified, further diagnostic clarification is often necessary to determine the exact nature and severity of the damage.
Treatment Protocols: Rest and immobilization of the affected finger using splints or buddy taping to reduce movement and promote healing Ice application to decrease swelling and pain, typically in 15-20 minute intervals Nonsteroidal anti-inflammatory drugs (NSAIDs) to manage pain and inflammation Physical therapy or hand exercises to restore movement and strength once initial healing has occurred In cases of significant injury or tear, surgical intervention may be necessary to repair damaged tendons or fascia Follow-up assessments to monitor healing and prevent complications
