ICD-10: G57.71

Causalgia, specifically coded as G57.71 in the ICD-10-CM system, refers to a complex pain syndrome that primarily affects the right lower limb. This condition is characterized by severe, burning pain that typically follows an injury to a peripheral nerve. Below is a detailed clinical description and relevant information regarding this diagnosis.

Clinical Description of Causalgia (G57.71)

Definition and Symptoms

Causalgia is a type of neuropathic pain that arises after a traumatic injury to a nerve, often accompanied by other symptoms such as:

• Burning Sensation: Patients frequently report a burning pain that can be debilitating.
• Allodynia: This is a condition where normally non-painful stimuli, such as light touch, cause pain.
• Hyperalgesia: An increased sensitivity to painful stimuli is common in affected areas.
• Swelling and Changes in Skin Color: The affected limb may exhibit changes in temperature, color, and swelling, which can be indicative of the underlying nerve damage.

Etiology

Causalgia typically occurs following a traumatic event, such as:

• Fractures: Bone injuries can lead to nerve damage.
• Surgical Procedures: Surgical interventions in the lower limb may inadvertently affect nearby nerves.
• Infections: Certain infections can also lead to nerve injury and subsequent causalgia.

Diagnosis

The diagnosis of causalgia involves a comprehensive clinical evaluation, including:

• Patient History: A detailed history of the injury and symptom onset is crucial.
• Physical Examination: Neurological examinations to assess sensory and motor function in the affected limb.
• Diagnostic Imaging: Imaging studies, such as MRI or CT scans, may be utilized to identify any structural abnormalities or nerve damage.

Treatment Options

Management of causalgia often requires a multidisciplinary approach, including:

• Medications: Analgesics, anticonvulsants (like gabapentin), and antidepressants (such as amitriptyline) are commonly prescribed to manage pain.
• Physical Therapy: Rehabilitation exercises can help improve function and reduce pain.
