We describe five patients, seen since 1984, with posterior shoulder pain and isolated wasting and weakness of the infraspinatus. In four of these a ganglion in the spinoglenoid notch was demonstrated by MRI and in one recent case ultrasound scans were positive. Three patients have been treated by operation, but there was recurrence in one after five years. In each confirmed case, the ganglion straddled the base of the spine of the scapula, extending into both supraspinatus and infraspinatus fossae. The nerve was either compressed against the spine or stretched over the posterior aspect of the ganglion. Adequate surgical exposure is essential to preserve the nerve to the infraspinatus and to allow complete removal of the ganglion. This is difficult because of the location and thin-walled nature of the cysts.

In this paper we report the clinical and electrophysiological study of a patient with suprascapular nerve entrapment. The patient was initially diagnosed as having shoulder pain due to tendinitis, since his job involved continuous loading of the affected shoulder with heavy weights. Later, clinical exploration revealed wasting of the supra and infraspinatus muscles. Electrophysiological study confirmed the diagnosis of a neuropathy of the suprascapular nerve at the level of the coracoid notch, which improved with conservative treatment. This case report stresses the importance of suprascapular nerve entrapment as a causal factor for shoulder pain; it has an occupational origin which should be taken into account in the differential diagnosis of shoulder pain syndromes.

A man with shoulder pain, wasting, and weakness had ipsilateral cranial nerve abnormalities. Electrodiagnostic studies supported a diagnosis of neuralgic amyotrophy, but we later demonstrated a spinal accessory mononeuropathy with ipsilateral hypoglossal weakness (Collet-Sicard syndrome). Magnetic resonance imaging demonstrated an inaccessible occipital condyle mass, and disseminated adenocarcinoma was subsequently diagnosed. Although cranial mononeuropathies can occur in neuralgic amyotrophy, this case illustrates the importance of identifying a focal lesion, and highlights the localizing value of electrodiagnosis.

Wheelchair athletes are susceptible to injuries related to overuse of the shoulder, in particular shoulder impingement syndrome. The present study examined the relationship of shoulder pain to demographic details, isokinetic strength and muscle balance in 8 elite quadriplegic rugby players. Demographic data were collected using personal interviews and each subject was clinically examined for signs of impingement syndrome by a physician. In addition each subject underwent bilateral isokinetic strength testing of the shoulder at 60 and 180 deg/s for abduction/adduction and internal/external rotation. A series of step-wise multiple discriminant analysis successfully predicted clinical symptoms from demographic, muscular strength and balance data. In particular, there was a significant deficit in adductor strength and this was related to shoulder pain and wasting of the scapular muscles. This strength deficit may be due to the high level of spinal lesions in the quadriplegic population. The level of spinal lesion may contribute to the aetiology of shoulder pathology in quadriplegia, and differentiate it from that observed in able-bodied athletes who exhibit weak abductors.

A 35 year old man presented to his general practitioner with severe right shoulder pain and subsequent weakness and wasting of the muscles in the affected shoulder girdle three weeks after a dental filling. His symptoms persisted despite standard treatment. He developed malaise, night sweats, weight loss, a petechial rash and a microcytic anaemia. On admission to hospital three months after the start of his symptoms he had also developed splenomegaly and the murmur of aortic regurgitation. Investigations confirmed the diagnoses of infective endocarditis and neuralgic amyotrophy. In this case neuralgic amyotrophy appears to have been the presenting feature of infective endocarditis. This association has not previously been described.

Suprascapular entrapment neuropathy is well known in certain athletes, especially volleyball players. A brother and sister presented with right shoulder pain and wasting of the scapular muscles, particularly the infraspinatus. They had played volleyball for over six years and were forced to retire because of disability. Investigations showed involvement of the rhomboid muscles also, suggesting a probable extension of this syndrome to other nerves in the region such as the dorsal scapular nerve.

Entrapment neuropathy of the suprascapular nerve (SNE), although a recognised clinical entity, is a relatively rare cause of shoulder pain and subjective weakness in the athlete involved in overhead sports like volleyball and badminton. This study deals with the presentation and management of four unusual cases of suprascapular nerve entrapment in volleyball players. Four male volleyball players presented to our department with intractable shoulder pain and subjective sensation of shoulder weakness. They all had visible wasting of both supraspinatus and infraspinatus muscles, together with weakness of abduction and external rotation of the arm. They all responded temporarily to a diagnostic injection of local anaesthetic. MR imaging was useful in diagnosing space occupying lesions in three cases and the presence of a hypertrophic suprascapular ligament in one case. Due to failure of non- operative treatment, which included activity modification, rest, analgesics and rehabilitation programme over 6 months, surgery was then required to decompress the suprascapular nerve. All patients were symptom free at 6 months postoperatively and after an intensive rehabilitation programme, they were able to return to their normal level of activity including sport.

We report a case of apparently sporadic amyotrophic lateral sclerosis (ALS) in a young pregnant woman presenting subacutely with severe left shoulder pain followed by progressive weakness and wasting of the left arm, mimicking neuralgic amyotrophy. She was later found electrophysiologically to have widespread denervation involving more than just the arm and an alanine for valine substitution in codon 4 (A4V) in the gene for Cu/Zn superoxide dismutase 1 (SOD1). Her case illustrates that pain on initial presentation, though uncommon, does not exclude a diagnosis of ALS.

Parsonage-Turner syndrome, also known as acute brachial neuritis or neuralgic amyotrophy, can be caused by various infectious agents. We report on four patients who experienced Parsonage-Turner syndrome as the first manifestation of Lyme disease. The clinical picture was typical, with acute shoulder pain followed rapidly by weakness and wasting of the shoulder girdle muscles. Electrophysiological testing showed denervation. A single patient reported erythema chronicum migrans after a tick bite. Examination of the cerebrospinal fluid showed lymphocytosis and protein elevation in 3 patients. Serological tests for Lyme disease were positive in the serum in all 4 patients and in the cerebrospinal fluid in 2 patients. Antibiotic therapy ensured a favorable outcome in all 4 cases. Two patients achieved a full recovery within 6 months. Parsonage-Turner syndrome should be added to the list of manifestations of neuroborreliosis. Serological tests for Lyme disease should be performed routinely in patients with Parsonage-Turner syndrome.

Parsonage-Turner syndrome (PTS) is a rare syndrome of unknown cause, affecting mainly the lower motor neurons of the brachial plexus. The brachial plexus is a group of nerves that conduct signals from the spine to the shoulder, arm, and hand. PTS is usually characterized by the sudden onset of severe 1-sided shoulder pain, followed by paralysis of the shoulder and lack of muscle control in the arm, wrist, or hand several days later. PTS can vary greatly in presentation and nerve involvement. Also known as brachial plexus neuritis or neuralgic amyotrophy, PTS is a common condition characterized by inflammation of a network of nerves that control and supply, or innervate, the muscles of the chest, shoulders, and arms. Individuals with the condition first experience severe pain across the shoulder and upper arm. Within a few hours or days, weakness, wasting (atrophy), and paralysis may affect the muscles of the shoulder. Although individuals with the condition may experience paralysis of the affected areas for months or, in some cases, years, recovery is usually eventually complete.
