Sprains and strains of joints are common injuries that can occur during physical activities or accidents. They involve the stretching or tearing of ligaments (sprains) or muscles/tendons (strains) around a joint. This guide aims to provide an overview of the symptoms, causes, diagnostic steps, possible interventions, and lifestyle interventions for sprain/strain of joint NOS.


– ICPC-2 Code: L79 Sprain/strain of joint NOS
– ICD-10 Code: S93.6 Sprain and strain of other and unspecified parts of foot


  • Pain: localized pain around the affected joint
  • Swelling: visible swelling or edema around the joint
  • Bruising: discoloration or bruising around the joint
  • Limited range of motion: difficulty moving the joint fully
  • Instability: feeling of joint instability or giving way


  • Trauma: sudden force or impact to the joint, such as a fall or collision
  • Overuse: repetitive stress or strain on the joint, often seen in athletes or individuals with repetitive job tasks

Diagnostic Steps

Medical History

  • Gather information about the patient’s recent activities or events that may have led to the injury
  • Identify any previous history of joint injuries or conditions
  • Assess any risk factors for joint injuries, such as age, obesity, or poor conditioning

Physical Examination

  • Inspect the affected joint for swelling, bruising, or deformity
  • Palpate the joint to assess for tenderness or instability
  • Evaluate the range of motion and strength of the joint
  • Perform specific joint tests, such as the Lachman test for knee stability or the anterior drawer test for ankle stability

Laboratory Tests

  • No specific laboratory tests are typically required for the diagnosis of sprain/strain of joint NOS

Diagnostic Imaging

  • X-rays: may be used to rule out fractures or dislocations
  • Ultrasound: can help visualize soft tissue injuries, such as ligament or tendon tears
  • MRI: provides detailed images of soft tissues, useful for assessing ligament or muscle injuries

Other Tests

  • Arthroscopy: a minimally invasive procedure that allows direct visualization of the joint using a small camera
  • Electromyography (EMG): may be used to assess muscle function and identify any nerve involvement

Follow-up and Patient Education

  • Provide instructions for at-home care, such as rest, ice, compression, and elevation (RICE)
  • Advise the patient on the expected recovery timeline and when to seek further medical attention
  • Educate the patient on injury prevention strategies, such as proper warm-up, stretching, and strengthening exercises

Possible Interventions

Traditional Interventions


Top 5 drugs for Sprain/strain of joint NOS:

  1. Nonsteroidal anti-inflammatory drugs (NSAIDs) (e.g., Ibuprofen, Naproxen):
    • Cost: Generic versions can be $3-$20/month.
    • Contraindications: Active peptic ulcer disease, history of gastrointestinal bleeding, allergy to NSAIDs.
    • Side effects: Upset stomach, heartburn, dizziness.
    • Severe side effects: Gastrointestinal bleeding, kidney problems, allergic reactions.
    • Drug interactions: Blood thinners, ACE inhibitors, diuretics.

    • Contraindications: Allergy to local anesthetics (for lidocaine patches), broken or irritated skin.
    • Side effects: Local skin reactions, such as redness or itching.
    • Severe side effects: Rare, but may include severe allergic reactions.
    • Drug interactions: None significant.
    • Warning: Follow instructions for proper application and avoid contact with eyes or mucous membranes.
  5. Corticosteroids (e.g., Prednisone):
    • Cost: Generic versions can be $10-$30/month.
    • Contraindications: Active infections, systemic fungal infections, allergy to corticosteroids.
    • Side effects: Increased appetite, weight gain, mood changes.
    • Severe side effects: Increased risk of infections, osteoporosis, adrenal suppression.
    • Drug interactions: NSAIDs, anticoagulants, antidiabetic medications.
    • Warning: Prolonged use may require gradual tapering to avoid adrenal insufficiency.

Alternative Drugs:

  • Topical NSAIDs (e.g., Diclofenac gel): Provides localized pain relief with fewer systemic side effects.
  • Oral analgesics (e.g., Tramadol): May be used for more severe pain not adequately controlled by other medications.
  • Muscle relaxants (e.g., Methocarbamol): Alternative option for muscle relaxation.
  • Topical counterirritants (e.g., Menthol cream): Provides a cooling or warming sensation to relieve pain.
  • Antidepressants (e.g., Amitriptyline): Can be used for chronic pain management.

Surgical Procedures:

  • Surgery is typically not required for sprain/strain of joint NOS. However, in severe cases with significant ligament or tendon tears, surgical repair may be considered.

Alternative Interventions

  • Physical therapy: Helps improve joint stability, range of motion, and strength. Cost: $50-$150 per session.
  • Chiropractic care: May provide pain relief and improve joint function through manual adjustments. Cost: $50-$200 per session.
  • Acupuncture: May help reduce pain and promote healing. Cost: $60-$120 per session.
  • Massage therapy: Can help relax muscles, reduce pain, and improve circulation. Cost: $50-$100 per session.
  • Homeopathic remedies: Some individuals find relief with homeopathic treatments, such as Arnica or Ruta graveolens. Cost: Varies depending on the specific remedy.

Lifestyle Interventions

  • Rest and activity modification: Avoid activities that exacerbate pain or strain on the joint.
  • Ice and heat therapy: Apply ice packs or cold compresses for the first 48 hours, then switch to heat therapy to promote healing and reduce pain.
  • Compression and elevation: Use compression bandages or braces to support the joint and elevate the affected limb to reduce swelling.
  • Physical activity and exercise: Engage in low-impact exercises and rehabilitation exercises to improve joint strength and flexibility.
  • Weight management: Maintain a healthy weight to reduce stress on the joints.
  • Proper footwear and equipment: Use appropriate footwear and protective equipment during physical activities to prevent injuries.

It is important to note that the cost ranges provided are approximate and may vary depending on the location and availability of the interventions.
