M65.17
Other infective (teno)synovitis, ankle and foot
Clinical Classification Guidelines
Medical Intelligence & Overview
Other infective (teno)synovitis of the ankle and foot, classified under ICD-10 code M65.17, is an inflammatory condition caused by infection that affects the tendons, synovial sheaths, and joint spaces of these regions. This condition can result from bacterial, fungal, or other microbial infections and often leads to pain, swelling, and limited movement. Recognizing and understanding this condition is vital for timely management and treatment.
Causes & Symptoms
Clinical Causes: Bacterial infections, such as Staphylococcus aureus or Streptococcus species, entering through cuts, punctures, or wounds near the ankle or foot. Spread from nearby infections or via bloodstream ( septicemia ). Fungal infections affecting the synovial tissues. Injuries or trauma that introduce infectious agents into the joint or tendon sheaths. Pre-existing conditions that compromise immunity, increasing susceptibility to infection. Repetitive strain or overuse leading to micro-injuries that can become infected.
Key Symptoms: Pain localized around the ankle or foot, often worsening with movement. Swelling and warmth over affected areas. Tenderness when touching the affected region. Limited range of motion of the ankle or foot joints. Redness of the skin over the affected structures. Possible fever and general malaise in cases of systemic infection. Crepitus or a feeling of grating in the joint or tendon sheaths during movement.
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a combination of clinical evaluation and diagnostic tests, including: - Medical history review focusing on recent injuries or infections. - Physical examination assessing swelling, tenderness, and range of motion. - Imaging studies such as X-rays to exclude other causes of joint swelling. - Ultrasound to detect fluid accumulation around tendons and joints. - Joint aspiration or synovial fluid analysis to identify infectious organisms and assess the presence of pus. - Blood tests including complete blood count (CBC) and inflammatory markers like ESR and CRP. - Cultures from synovial fluid or tissue samples to pinpoint the infectious agent.
Treatment Protocols: Managing infective (teno)synovitis of the ankle and foot typically requires a combination of interventions: - Antibiotic therapy tailored to the identified pathogen, often administered intravenously initially. - Surgical intervention may be necessary to drain abscesses, debride infected tissue, or remove damaged tendons or synovial tissue. - Rest and immobilization of the affected joint or tendon to reduce strain and facilitate healing. - Pain management with appropriate medications. - Follow-up care to monitor response to treatment, prevent complications, and restore function. - In some cases, physical therapy is recommended after the infection resolves to regain mobility and strength.
