M71.33
Other bursal cyst, wrist
Clinical Classification Guidelines
Medical Intelligence & Overview
An other bursal cyst of the wrist is a fluid-filled sac that forms near the wrist joint, specifically within a bursa. Bursae are small, fluid-filled sacs that act as cushions between bones, tendons, and muscles to reduce friction during movement. When these sacs become inflamed or filled with excess fluid, they can develop into cysts. The condition identified by ICD-10 code M71.33 refers to a bursal cyst located specifically in the wrist area. Often, these cysts are not dangerous but can cause discomfort, swelling, and limited movement if they grow large enough or press against surrounding tissues.
Causes & Symptoms
Clinical Causes: Repeated overuse or stress on the wrist leading to inflammation Trauma or injury to the wrist area Degenerative joint conditions such as osteoarthritis Degeneration of the bursa over time Previous injuries or surgeries in the wrist area
Key Symptoms: Visible swelling or lump on the wrist Pain or tenderness around the cyst, especially when moving the wrist Restricted movement or stiffness in the wrist Discomfort during physical activities involving the wrist In some cases, the cyst may be tender or warm to the touch if inflamed
Diagnostic & Treatment
Diagnosis Path: Healthcare providers typically diagnose a wrist bursal cyst through a physical examination, noting the swelling and assessing the range of motion. Imaging tests such as ultrasound are often used to confirm the presence of a cyst and to distinguish it from other possible conditions like tumors or ganglion cysts. MRI scans may be recommended if more detailed images are needed to assess the cyst's size and its relationship with surrounding tissues.
Treatment Protocols: Treatment options vary depending on the size of the cyst and associated symptoms. Common approaches include: - Observation: Small, asymptomatic cysts may not require immediate treatment and can be monitored for changes. - Aspiration: Draining the fluid from the cyst with a needle can provide relief, though recurrence is possible. - Immobilization: Wearing a wrist splint or brace to reduce movement and promote healing. - Physical Therapy: Exercises to strengthen the wrist and improve function. - Surgery: If the cyst causes significant discomfort or interferes with daily activities, surgical removal may be considered. The procedure involves excising the cyst and the bursa to prevent recurrence. Post-treatment care typically includes rest, ice application, and follow-up visits to monitor healing and prevent complications.
