ICD-10 Code: M00.029
Condition: Staphylococcal Arthritis, Unspecified Elbow

Overview

Staphylococcal arthritis refers to an infection of the joint caused by Staphylococcus bacteria, which are commonly found on the skin and in the nasal passages. This condition can lead to inflammation, pain, and swelling in the affected joint. The elbow, being a hinge joint, is susceptible to such infections, particularly in individuals with compromised immune systems or those who have experienced trauma to the area.

Clinical Presentation

Patients with staphylococcal arthritis typically present with the following symptoms:

• Joint Pain: Severe pain in the elbow joint, which may worsen with movement.
• Swelling: Noticeable swelling around the elbow, indicating inflammation.
• Redness and Warmth: The skin over the joint may appear red and feel warm to the touch, suggesting an active infection.
• Limited Range of Motion: Patients may experience difficulty in moving the elbow due to pain and swelling.
• Systemic Symptoms: In some cases, patients may exhibit fever, chills, or malaise, indicating a more systemic infection.

Etiology

Staphylococcal arthritis is primarily caused by Staphylococcus aureus, a bacterium that can enter the joint space through various means, including:

• Direct Inoculation: Following trauma, surgery, or injection into the joint.
• Hematogenous Spread: The bacteria can spread from other infected sites in the body through the bloodstream.

Diagnosis

Diagnosis of staphylococcal arthritis typically involves:

• Clinical Evaluation: A thorough history and physical examination to assess symptoms and joint function.
• Imaging Studies: X-rays or MRI may be used to evaluate joint damage or effusion.
• Laboratory Tests: Synovial fluid analysis through arthrocentesis (joint aspiration) can confirm the presence of Staphylococcus bacteria, along with blood cultures to identify systemic infection.

Treatment

Treatment for staphylococcal arthritis generally includes:

• Antibiotic Therapy: Initiation of appropriate antibiotics based on culture results. Methicillin-resistant Staphylococcus aureus (MRSA) may require specific antibiotics.
• Joint Aspiration: Removal of infected fluid from the joint to relieve pressure and pain.
• Surgical Intervention: In severe cases, surgical drainage or debridement may be necessary to remove infected tissue.

Prognosis

The prognosis for staphylococcal arthritis largely depends on the timeliness of diagnosis and treatment. Early intervention typically leads to better outcomes, while delayed treatment can result in joint damage or chronic infection.

Conclusion
