Clinical and pathologic studies of synovitis in polymyalgia rheumatica.

Clinically detectable joint swelling was found in 10 of 13 fully evaluated patients considered to have polymyalgia rheumatica. Five patients had some joint findings at disease onset. Knees were most commonly affected. Sternoclavicular involvement was seen in 3 patients. Joint effusions in 8 patients had 300-5,700 leukocytes/mm3 with a mean of 2,900. Six synovial biopsy specimens studied by light microscopy revealed mild to moderate synovial proliferation and chronic inflammation that was generally less severe than in typical rheumatoid arthritis. Electron microscopy identified microvascular changes and large amounts of vesicular and granular debris in lining cells. In 1 patient, a "fingerprint" pattern in the granular material was suggestive of the findings in some immune complexes. This still unexplained synovitis may, as previously suggested, be important in the pathogenesis of the polymyalgia rheumatica syndrome.

Pustulotic arthroosteitis.

We describe the case of a white male with chronic inflammation of one knee, the sternoclavicular area and the dorsal spine, who also had pustulosis palmaris et plantaris. Radiological changes were suggestive of pustulotic arthroosteitis. Our patient had prominent peripheral joint changes not previously emphasized.

Sternoclavicular dislocation. Treatment and complications.

Based on Allman's classification, the authors conducted a critical study on the results of treatment of 17 sternoclavicular dislocations, 14 anterior and 3 posterior. They propose conservative treatment for subluxations and operative treatment for total dislocations, particularly when posterior. Tomography was required for precise diagnosis. The advantages of open reduction are stressed and the complication of intra-thoracic migration of crossed Kirschner wires used to stabilise reduction and capsular suturing is described.

Posterior sternoclavicular dislocation: a case report.

Posterior sternoclavicular dislocation is a relatively rare form of trauma, but one that must be recognized by the emergency physician. Such a case is presented here. Due to the proximity of the clavicle to critical thoracic outlet structures, serious complications can arise from a posterior dislocation: impingement on and possible trauma to the trachea, pneumothorax, laceration of underlying great vessels, brachial plexus injury, esophageal trauma, and laryngeal trauma that may cause permanent vocal cord changes. Many of these potential complications are life-threatening, and it is important that this injury not be triaged in the emergency department as a minor injury, thereby leading to its improper or delayed treatment.

[Shoulder girdle injury in childhood. Operation or conservative procedure?].

The fracture of the clavicle is a very frequent injury to children and young adults. Using a figure-of-eight bandage for treatment leads to good functional result and acceptable cosmetical appearance. Indications for an open reduction are rare: they are confined to brachial plexus lesions, injuries to the subclavian vessels, open fractures or fractures of the outer third of the clavicle combined with an acromioclavicular separation. Fractures of the scapula merely require immobilization and subsequent physiotherapy to yield satisfactory results. Distorsions and subluxations of the joints of the clavicle are to be managed conservatively, too. Only in cases of complete ruptures of the acromioclavicular, coracoclavicular or sternoclavicular ligaments, it is necessary to perform an open reduction and repair of the ligaments.

[Posterior dislocation of the median end of the clavicle].

Authors discuss, based on the experiences gained in the operative treatment of posterior sternoclavicular dislocation in two patients, the frequency, the symptoms, the classification, the diagnosis and treatment of this rare injury. One of the two injuries was fresh the other inveterated. No description of the operative treatment of similar injuries was found in the literature of this country. Finally the importance of the early recognition and the definitive treatment of this rare dislocation are stressed.

Sternoclavicular brucellar arthritis: a report of 7 cases and a review of the literature.

OBJECTIVE: To describe the clinical features of sternoclavicular arthritis. METHODS: Medical records review of patients with sternoclavicular brucellar arthritis diagnosed and treated in a University Hospital in Lima, Peru. RESULTS: Over a 21-year period, 1,729 cases of brucellosis were diagnosed and treated. Seven patients with sternoclavicular arthritis were identified; 5 had an acute course with current or past evidence of systemic infection. Four patients had involvement of another joint and one of the 7 developed a chest wall abscess. All patients recovered without sequelae. CONCLUSION: Recovery without sequelae is expected if patients with sternoclavicular brucellar arthritis are promptly diagnosed and treated.

Intracardiac malpositioning of a sternoclavicular fixation wire.

A case of intracardiac malpositioning of a sternoclavicular Kirschner pin is reported. After an uneventful closed wire-fixation of sternoclavicular subluxation and a normal postanesthetic recovery, a 17-year-old male patient developed opacification of the right hemithorax and signs of internal bleeding. The lateral chest roentgenogram showed one fixation wire protruding deeply into the anterior mediastinum. Sternotomy showed a large pericardial tear communicating with the right pleural cavity and a puncture hole of the right auricle that had caused a blood loss of 3 L into the pleural space. Although the surgical repair was uneventful, the patient eventually died as a sequelae to prolonged cerebral hypoxemia.

Skeletal disease, arthro-osteitis, in adult patients with pustulosis palmoplantaris.

A follow-up study of 13 patients with pustulosis palmoplantaris (PPP) and skeletal disease is reported. A prolonged and fluctuating course occurred in all patients. Nine patients had anterior chest wall involvement with erosions or ankylosis of the sternoclavicular, first sternocostal and/or manubriosternal joint together with sclerosis and often hyperostosis of adjacent bones, ossification/calcification of the first costal cartilage, and in 7 patients of the costoclavicular ligament. Spinal involvement in the form of spondylodiscitis, sclerosis of vertebral bodies, syndesmophytes, paravertebral ossifications and/or spondyloarthritis occurred in 11 patients, three of whom also had involvement of the sacroiliac joints. One patient had sclerosis of a pubic and ischial bone. Peripheral arthritis or tenosynovitis occurred in 5 patients, two of whom had signs of enthesopathy, and one also erosions. The presence of a distinct PPP syndrome is suggested.

Anterior subluxation after reduction of a posterior traumatic sterno-clavicular dislocation: a case report and a review of the literature.

Sternoclavicular dislocations represent a rare injury. Based on our clinical experience with a patient showing an anterior subluxation after reduction of a posterior traumatic dislocation, we review the literature. The emergent reduction of the dislocation is mandatory, always keeping in mind the potentially devastating neurovascular complications. If the treatment of a residual anterior instability remains controversial, a residual posterior instability should be treated by a surgical procedure. The optimal treatment depends mainly on each surgeon's choice and practice.

Scapulothoracic dissociation.

Scapulothoracic dissociation is a rare entity that consists of disruption of the scapulothoracic articulation. The mechanism of injury is probably traction caused by a blunt force to the shoulder girdle. This lesion is characterized by massive soft-tissue swelling of the shoulder; lateral displacement of the scapula, measured radiographically; an injury to bone (an acromioclavicular separation, a displaced fracture of the clavicle, or a sternoclavicular disruption); a severe neurovascular injury; and a variety of upper and lower-extremity fractures. We treated fifteen patients who had this lesion, most of whom had several associated injuries. Three patients died: two from exsanguination and one from a cardiac arrest. In most patients, the damaged artery was repaired and the brachial plexus was explored. All of the twelve patients who had a complete brachial-plexus injury were left with a flail upper extremity. Most patients refused amputation.

Shoulder injuries during alpine skiing.

We retrospectively reviewed alpine skiing injuries at a destination ski resort during three seasons to characterize the incidence and types of shoulder injuries. A total of 3451 injuries in 3247 patients were reviewed. The overall injury rate was 4.44 injuries per 1000 skier-days. Injuries to the upper extremity represented 29.1% (N = 1004) of all alpine ski injuries. Injuries involving the shoulder complex (393 injuries in 350 patients) accounted for 39.1% of upper extremity injuries and 11.4% of all alpine skiing injuries. The rate of shoulder injury was 0.51 injuries per 1000 skier-days. Patients with shoulder injuries had a mean age of 35.4 years, and the male-to-female ratio of these patients was 3:1. Falls represented the most common mechanism of shoulder injury (93.9%) in addition to collisions with skiers (2.8%), pole planning (2.3%), and collisions with trees (1%). The most common shoulder injuries were rotator cuff strains (24.2%), anterior glenohumeral dislocations or subluxations (21.6%), acromioclavicular separations (19.6%), and clavicle fractures (10.9%). Less common shoulder injuries included greater tuberosity fractures (6.9%), trapezius muscle strains (6.4%), proximal humeral fractures (3.3%), biceps tendon strains (2.3%), glenoid fractures (1.5%), scapular fractures (1%), humeral head fractures (1%), sternoclavicular separations (0.5%), an acromial fracture (0.3%), a posterior glenohumeral dislocation (0.3%), and a biceps tendon dislocation (0.3%).

Skeletal manifestations of polymyalgia rheumatica.

In a review of 39 patients with polymyalgia rheumatica (PMR), sternoclavicular and acromioclavicular arthropathy was noted in 15% and 10% of the patients, respectively. Diffuse clavicular swelling preceded the onset of PMR in one patient. Carpal tunnel syndrome was seen in four patients (10%).

Chronic sclerosing osteomyelitis of the iliac bone. Etiological possibilities.

An adolescent with chronic recurrent multifocal osteomyelitis located to both iliac bones and an adult with pustulotic arthro-osteitis, involving the left iliac bone, an invertebral space, and the sternoclavicular, first sternocostal, manubriosternal and single peripheral joints are described. Their iliac bone changes were identical, except for the occurrence of bilateral changes in the adolescent, and ankylosis of the sacroiliac joint in the adult. It is suggested that chronic recurrent multifocal osteomyelitis and pustulotic arthro-osteitis may be related diseases with age-dependent differences.

Septic arthritis in heroin addicts.

Over a 6-year period (1982 to 1988), 36 episodes of septic arthritis were diagnosed in 35 heroin addicts from Barcelona, Spain. Thirty (86%) were men and five (14%) were women, with a mean age of 24 years (range, 14 to 39). Twenty-nine episodes (80%) were monoarticular and seven (20%) were oligoarticular. The sacroiliac (16 cases), sternoclavicular (8), hip (5), and shoulder (4) joints were most frequently infected. Staphylococcus aureus and Pseudomonas aeruginosa were the etiological agents in 75% and 11% of episodes, respectively. Response to antibiotic treatment was good in 32 cases (90%), eight patients needed surgical drainage, and none died. We conclude that septic arthritis in heroin addicts localizes predominantly in axial joints. In our geographic area, infection with S aureus is more frequent than with gram-negative rods such as P aeruginosa or Serratia marcescens, which are most frequently found in reports from the United States.
