ICD-10: M71.46

The ICD-10 code M71.46 specifically refers to the clinical diagnosis of "calcium deposit in bursa, knee." This condition is part of a broader category of disorders characterized by the presence of calcific deposits in various anatomical locations, particularly in the bursae, which are small fluid-filled sacs that reduce friction between tissues in joints.

Clinical Description

Definition

Calcium deposits in the bursa occur when calcium salts accumulate in the bursal tissue, leading to inflammation and pain. The bursa acts as a cushion between bones and tendons or muscles around joints, and when it becomes calcified, it can result in discomfort and restricted movement.

Symptoms

Patients with calcium deposits in the knee bursa may experience:
- Localized Pain: Pain around the knee joint, particularly during movement or pressure.
- Swelling: Inflammation of the bursa can lead to visible swelling in the knee area.
- Reduced Range of Motion: Patients may find it difficult to fully extend or flex the knee due to pain or mechanical blockage.
- Tenderness: The affected area may be tender to touch, especially over the bursa.

Etiology

The exact cause of calcium deposits in the bursa is not always clear, but several factors may contribute, including:
- Age: Older adults are more prone to developing calcific deposits due to degenerative changes in the body.
- Overuse or Injury: Repetitive stress or trauma to the knee can lead to inflammation and subsequent calcification.
- Metabolic Disorders: Conditions that affect calcium metabolism, such as hyperparathyroidism, can increase the likelihood of calcification.

Diagnosis

Diagnosis of M71.46 typically involves:
- Clinical Examination: A healthcare provider will assess the knee for swelling, tenderness, and range of motion.
- Imaging Studies: X-rays or ultrasound may be used to visualize the calcium deposits and assess the extent of the condition.
- History Taking: Understanding the patient's medical history, including any previous injuries or underlying health conditions, is crucial.

Treatment

Management of calcium deposits in the knee bursa may include:
- Conservative Measures: Rest, ice application, and nonsteroidal anti-inflammatory drugs (NSAIDs) can help alleviate pain and reduce inflammation.
- Physical Therapy: Strengthening and stretching exercises may improve function and reduce symptoms.
- Injections: Corticosteroid injections may be administered to reduce inflammation.
- Surgical Intervention: In severe cases where conservative treatments fail, surgical removal of the calcified tissue may be considered.
