S64.01
Injury of ulnar nerve at wrist and hand level of right arm
Clinical Classification Guidelines
Medical Intelligence & Overview
An injury to the ulnar nerve at the wrist and hand level in the right arm can significantly affect hand function and sensation. The ulnar nerve is a vital nerve contributing to the sensory and motor functions of the hand and forearm. Damage to this nerve can result from various types of trauma or repetitive stress, leading to symptoms that may require medical attention and management.
Causes & Symptoms
Clinical Causes: Direct trauma or injury to the wrist or hand, such as cuts, fractures, or contusions Repeated pressure or compression of the nerve, such as during prolonged leaning on the elbow (cubital tunnel syndrome) or activities involving gripping Fractures of the distal humerus or forearm bones that impact the nerve's pathway Surgical procedures involving the wrist or hand that inadvertently damage the nerve Entrapment of the ulnar nerve within bony or soft tissue structures in the wrist, such as at Guyon's canal
Key Symptoms: Numbness or tingling sensation in the ring and little fingers Weakness in the hand, making it difficult to grip or hold objects Muscle wasting in the hand's intrinsic muscles, leading to a noticeable deformity known as a 'claw hand' Pain or discomfort along the inside of the elbow or wrist Reduced coordination and fine motor skills in the affected hand
Diagnostic & Treatment
Diagnosis Path: The diagnosis involves a detailed clinical evaluation, including a physical examination to assess motor strength, sensation, and muscle atrophy. Nerve conduction studies and electromyography (EMG) tests can help determine the location and severity of nerve damage. Imaging studies like X-rays or MRI may also be employed to identify associated injuries such as fractures or soft tissue damage.
Treatment Protocols: Management of ulnar nerve injury depends on the severity and cause of the injury. Common treatment approaches include:
