Compressive radial neuropathies.

Radial neuropathy can have one of several clinical presentations, depending on the level of compression: high radial nerve palsy, PIN palsy, radial tunnel syndrome, and Wartenberg's syndrome. Elucidating the history and progression of symptoms with a physical examination directed at testing individual muscles will determine the approximate anatomic level of radial injury. Identification of a Tinel's sign will often locate the site of compression. Electrodiagnostic studies can confirm the diagnosis in a radial motor neuropathy, but are unreliable in radial tunnel syndrome and sensory radial nerve compression. A trial of nonsurgical treatment is warranted in all cases except those with progressive motor weakness or palsy. Patients who do not respond or continue to progress despite conservative treatment are candidates for surgical decompression.

Posterior antebrachial cutaneous nerve conduction study in radial neuropathy.

Radial neuropathy most commonly occurs as a result of external compression at the spiral groove region. The posterior antebrachial cutaneous nerve (PACN) conduction study was performed in 15 consecutive patients with radial palsy. Unilateral PACN abnormalities were present in 11 patients. A normal PACN study was correlated with clinical improvement at 3 months. Conversely, PACN abnormality was correlated with radial motor axon loss and a poorer prognosis. The PACN study is a simple adjunct which provides additional information relating to the diagnosis and prognosis of radial lesions.

AAEM case report #27: acute retrohumeral radial neuropathies.

Acute radial neuropathies localized to the retrohumeral course of the radial nerve are common. Most individuals fully recover within a matter of days or, at the most, a few weeks. In a few, recovery may take longer and occasionally remains incomplete. In almost all instances the site of injury to the radial nerve can be accurately localized to the region of the spiral groove and the relative contributions of conduction block and axonal degeneration assessed using electrophysiologic techniques.

Radial neuropathy.

The radial nerve is the largest branch of the brachial plexus, and is commonly involved in upper extremity mononeuropathies. The radial nerve is primarily responsible for motor innervation of the upper extremity extensors, as well as receiving cutaneous innervation from most of the posterior arm, forearm, and hand. There are a variety of sites at which the radial nerve is susceptible to trauma and entrapment. Localizing radial nerve lesions is dependent on clinical knowledge of radial nerve anatomy, and sensory and motor examination.

Isolated triceps weakness in exercise-induced radial neuropathy.

OBJECTIVE: We report a case of isolated triceps weakness resulting from radial neuropathy. PATIENT: A middle-aged healthy man, a keen athlete, developed acute weakness of the triceps brachii muscle due to radial neuropathy. No other radial nerve innervated muscles were involved. Triceps function completely recovered in six weeks clinically and electrophysiologically suggesting focal conduction block secondary to demyelination. DISCUSSION: Acute radial neuropathy after strenuous arm exercise resulting from a compression lesion with acute conduction block, has been previously described. However, all reported cases involved severe weakness of radial nerve innervated distal muscles with wrist drop, while isolated weakness of the triceps brachii muscle in radial neuropathy has never been previously described. CONCLUSIONS: We suggest that selective weakness in the triceps could be the sole manifestation of an exercise-related radial neuropathy. This particular type of radial neuropathy could be a variant of neuralgic amyotrophy.

[Radial neuropathy after peripheral venous puncture].

We report a case of left radial neuropathy from a venipuncture, in a 59-year-old woman. She had a history of amputation of the four last fingers of the right hand, when she was 27-year-old. One year before, she had a difficult venipuncture of the left radial vein, for a preanaesthetic assessment for cataract surgery. The puncture elicited an excruciating pain, associated with hypoaesthesia in the area of the radial nerve, at forearm and the wrist. Conventional therapeutic means had only a minor efficiency. The concept of nervous system sensitizing is discussed. Prevention is essential.

Superficial radial neuropathy.

Isolated neuropathy of the cutaneous branch of the radial nerve is a rarely recognised condition. Five cases were described in 1932 by Wartenberg, who suggested the name cheiralgia paraesthetica. The condition has also been described as Wartenberg's disease. Twelve cases of isolated neuropathy of the cutaneous branch of the radial nerve are described, the literature is reviewed and the clinical picture outlined. In six of the cases the condition subsided without treatment, in two there was a good response to local injection of hydrocortisone, and in four cases a satisfactory result followed resection of the nerve. The course and distribution of the superficial branch of the radial nerve are described. The need to avoid the nerve during operations around the wrist is stressed.

Windmill pitcher's radial neuropathy.

The authors present two cases of severe radial nerve injury with different sites of pathology but a similar mechanism: the "windmill" pitching motion of competitive softball. Both patients required surgical intervention with neurolysis, and both improved postoperatively. The literature on related radial nerve injuries is briefly reviewed and pathophysiological mechanisms are discussed.

Treatment of radial neuropathy associated with fractures of the humerus.

Twenty-four humeral-shaft fractures with associated radial-nerve injuries in twenty-three patients with adequate follow-up were seen over a fifteen-year period. Initial treatment was closed in all but one patient, in whom débridement of an open fracture revealed a lacerated radial nerve. All patients had complete return of radial-nerve function. Two of the twenty-four nerve lesions were treated by delayed operation: one at fourteen weeks for entrapment in fracture callus, and the other at six weeks for repair of the aforementioned lacerated radial nerve. Thus, only 8 per cent of the patients required exploration of the nerve, all of whom did well after delayed repair. We recommend careful observation for return of nerve function and exploration at three and a half to four months after injury if there is still no clinical or electromyographic evidence of recovery at that time.

Localized constrictive radial neuropathy in the absence of extrinsic compression: three cases.

Three patients, one with bilateral disease, experienced spontaneous onset of radial nerve dysfunction. Each demonstrated significant motor paralysis and had surgical exploration 3 weeks to 3 months after symptoms were first noted. All three patients showed well-localized hourglass constrictions of the radial nerve that could not be attributed to extrinsic compression. Each subsequently required tendon transfers for a persistent radial nerve palsy. Each showed electrical evidence of late recovery, although this was incomplete in two out of three.

Superficial radial neuropathy following venepuncture.

A 42-year-old female suffered excruciating pain and paraesthesia on venepuncture of the cephalic vein in her left wrist. The left superficial radial nerve was injured. A flexed wrist during venepuncture renders the superficial radial nerve immobile and vulnerable to being punctured by the needle. To reduce the risk of nerve injury during venepuncture, the phlebotomist should choose a large and visible vein and insert the needle at a 5-15 degrees angle with the skin. The wrist should be selected only if the veins in the antecubital area are deemed unsuitable. The feeling of an electric shock along the distribution of the nerve, or rupture of the vein during venepuncture, should alert the phlebotomist to the possibility of nerve injury and the procedure should be stopped immediately.

Proximal radial compression neuropathy.

Proximal radial nerve compression occurs infrequently and is diagnosed successfully even less frequently. A large clinical series of patients with proximal radial nerve compression neuropathy was reviewed to determine better the common symptoms, physical findings, and electrodiagnostic findings, and to identify the predictors of better or worse outcome after surgical decompression. Seventy-nine proximal radial compression neuropathies were treated in 71 patients by the same surgeon between 1991 and 2000. The most consistent symptoms were deep aching pain in the forearm, pain radiation to the neck and shoulder, and a "heavy" sensation of the affected arm. The most common physical findings were tenderness over the radial nerve at the supinator muscle level, pain on resisted supination, and the presence of a Tinel sign over the radial forearm. Electrophysiologic studies were of limited value in diagnosis, with 90% of patients having normal findings. On operation, prominent pathology of the posterior interosseous nerve was observed in 36 of 79 limbs (46%). Follow-up ranged from 12 to 86 months (mean, 21 months) with no significant complications or recurrence of symptoms. Of the 79 nerve decompressions, 77% had excellent recovery and 20% were judged to be good. Of 69 patients employed when treated, 60 resumed gainful employment, including 53 who returned to their regular jobs. Proximal radial compression neuropathies are uncommon but present with a basic constellation of symptoms and physical findings, and decompression can provide excellent relief of symptoms.

Sonography of entrapment neuropathies in the upper limb (wrist excluded).

The progressive refinement of broadband transducers with frequencies higher than 10 MHz and improved near-field resolution has enhanced the potential of sonography to evaluate a variety of nerve entrapment syndromes occurring in the upper limb, such as suprascapular neuropathy in the area of the spinoglenoid-supraspinous notch, the quadrilateral space syndrome (axillary neuropathy), radial neuropathy in the area of the spiral groove, the supinator syndrome (posterior interosseous neuropathy), the cubital tunnel syndrome (ulnar neuropathy), and the Kiloh-Nevin syndrome (anterior interosseous neuropathy). In these settings, high-resolution sonography can depict changes in the nerve's shape and echotexture and can depict many extrinsic causes of nerve entrapment.
