S66.116
Strain of flexor muscle, fascia and tendon of right little finger at wrist and hand level
Clinical Classification Guidelines
Medical Intelligence & Overview
A strain of the flexor muscles, fascia, and tendons in the right little finger at the wrist and hand involves overstretching or minor tearing of these structures. This type of injury is common in activities involving gripping, grasping, or repetitive motion. Although typically not severe, it can cause discomfort, swelling, and reduced finger mobility. Recognizing the symptoms and understanding the causes can help in managing this injury effectively.
Causes & Symptoms
Clinical Causes: Overuse or repetitive motions involving the finger and wrist, such as typing, playing musical instruments, or manual labor. Sudden forced movements or overstretching during sports or physical activities. Trauma or impact to the finger or wrist, such as dropping an object or hitting a surface. Poor ergonomics or improper technique during activities that strain the hand and fingers. Pre-existing weakness or prior injuries that increase susceptibility to strains.
Key Symptoms: Pain or tenderness at the affected area, especially during movement. Swelling or inflammation around the finger, wrist, or palm. Reduced flexibility or stiffness in the little finger. Weakness or difficulty gripping objects with the affected hand. Possible bruising or discoloration in the affected area. A feeling of tightness or a pulling sensation during finger movement.
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves a physical examination by a healthcare professional, during which the doctor assesses the range of motion, checks for swelling, tenderness, and strength in the finger and wrist. Imaging tests such as X-rays may be recommended to rule out fractures or other bone injuries, though they usually don't show soft tissue strains. In some cases, ultrasound or MRI scans can provide detailed views of the muscles, tendons, and fascia to confirm the extent of the injury.
Treatment Protocols: Rest the affected hand and avoid activities that cause pain or strain. Ice application to reduce swelling and numb the area—typically 15-20 minutes every few hours during the initial 48 hours. Use of compression bandages or finger splints to support and immobilize the finger if necessary. Over-the-counter pain relievers, like NSAIDs, to alleviate discomfort and inflammation. Gradual resumption of activity, guided by symptom improvement and healthcare advice. Physical therapy exercises to restore range of motion, strength, and flexibility as healing progresses. In rare cases, if the injury is severe or does not improve with conservative treatments, surgical intervention might be considered.
