Resorption of the undersurface of the distal clavicle in rheumatoid arthritis.

An elongated erosion on the undersurface of the distal clavicle, adjacent to the coracoid process, may be seen in the shoulder of a patient with rheumatoid arthritis. This finding is apparently related to inflammatory changes in the coracoclavicular ligament. Such an erosion may occur with or without additional radiographic alterations and, although not entirely specific, suggests rheumatoid arthritis.

Localized nodular synovitis of the knee: a report of two cases with abnormal arthrograms.

The arthrographic appearance in two cases of localized PVS of the knee involving the region of the infrapatellar fat pad is reported. Lesions in this area may present with confusing symptomatology, and the true abnormality may be overlooked in a search for meniscal lesion. The arthrographic picture is non-specific and a number of entities must be considered.

Arthrographic evaluation of injuries of the first metacarpophalangeal joint: gamekeeper's thumb.

The radiographic evaluation of gamekeeper's thumb is described in an experimental study in nine cadaveric hands. After the application of radial stress at the metacarpophalangeal joint in the extended and abducted thumbs in an attempt to create defects in the ulnar collateral ligament, initial and stress radiography and arthrography were employed. In four cadavers a fracture of the proximal phalanx was noted; stress radiography revealed variability in joint stability. Arthrography outlined ulnar extravasation in six of the nine cadavers; surgical confirmation of a capsular tear was obtained following careful dissection in each of these six cadavers. It would appear that plain films, stress radiography, and arthrography complement each other in the diagnosis of gamekeeper's thumb.

Clinical and radiographic "reankylosis" following hip surgery in ankylosing spondylitis.

Eleven patients with ankylosing spondylitis underwent reconstructive hip surgery (21 hips). In 10 of these hips multiple surgical procedures had been performed. The final procedure included total hip arthroplasties (16 hips), femoral cup arthroplasties (four hips) and an Austin-Moore prosthetic replacement (one hip). A clinical and radiographic evaluation in the postoperative period revealed a high incidence of decreased joint motion and heterotopic ossification. Clinically moderate to severe restriction of motion was noted in 12 hips, and in six of these "reankylosis" was present. Radiographically moderate to severe new bone formation was seen in 11 hips, and in nine of these "reankylosis" was suggested. An association of excessive ossification and multiple surgical procedures was evident. It would appear that when the prime indication for hip surgery in patients with ankylosing spondylitis is restricted motion, the operation may not be beneficial.

Avascular necrosis of the femoral head following cardiac transplantation: report of a case.

Avascular necrosis of the femoral head occurred following cardiac transplantation in a 28-year-old man. After cardiac surgery the patient was treated with prednisone and experienced 2 "rejection" episodes. Hip pain began 5 months postoperatively. Roentgenograms revealed rapidly progressive avascular necrosis in both hips. The sequence of events leading to avascular necrosis of bone in this patient is identical to that following other organ transplantations and includes steroid-induced hyperlipemia, fatty infiltration of the liver, systemic fat emboli to subchondral vessels and avascular necrosis.

The association of HL-A B27 with Forestier's disease (vertebral ankylosing hyperostosis).

Despite the lack of apophyseal or sacroiliac joint involvement, Forestier's disease (vertebral ankylosing hyperostosis) shares with the inflammatory forms of spondylitis, the roentgenographic appearance of spinal new bone formation. Because of this apparent similarity, the prevalence of the HL-A B27 antigen was determined in 47 white patients with Forestier's disease. Sixteen of the patients (34 per cent) possessed the B27 antigen (P is less than 0.001). The mere presence of B27 therefore, does not confirm the diagnosis of inflammatory spondylitis in all patients with roentgenographic evidence of osseous bridging. Applying available epidemiologic information, these data further suggest that patients with the B27 antigen may be at substantial risk of developing Forestier's disease. As Forestier's disease and virtually all of the other B27 associated arthropathies manifest abundant new bone, an association may exist between this antigen and genes controlling new bone formation.

Osteomyelitis and septic arthritis complicating hand injuries and infections: pathogenesis of roentgenographic abnormalities.

Osteomyelitis and pyarthrosis may complicate hand injuries and soft-tissue infections, resulting in characteristic radiographic findings. Evaluation of 78 patients revealed bone or joint abnormalities in 10% of individuals. Distinct pathways are available for spread of bacteria which become lodged in the soft tissues of the hand. Such routes include tendon sheaths, fascial planes and lymphatics. An understanding or pertinent anatomy allows the radiologist to predict the site and pattern of soft tissue, articular and osseous alterations.

Inter-relationship between radiocarpal and metacarpophalangeal joint deformities in rheumatoid arthritis.

The roentgen evaluation of 96 rheumatoid hands and wrists, supplemented with anatomic and pathologic material from cadavers and patients with rheumatoid arthritis, allowed evaluation of deformities at the radiocarpal and metacarpophalangeal articulations. Measurements of specific coordinates in these patients were compared to those in "controls" and, despite significant error introduced by variability in patient positioning during radiography, definite inter-relationships between radiocarpal and metacarpophalangeal malalignments became evident. Radial deviation at the wrist was associated with ulnar deviation of the digits producing the "zig-zig" deformity of the rheumatoid hand. The pathogenetic and therapeutic aspects of the roentgen findings are discussed.

Diffuse skeletal abnormalities in Forestier disease.

Forestier disease, or ankylosing hyperostosis, is a common disorder of middle-aged and elderly persons. Characteristic clinical and radiographic features enable the physician to distinguish between this disease and ankylosing spondylitis. The principal clinical features include aching spinal stiffness with relative preservation of function and minimal evidence of spinal immobility. Many patients have elbow and heel pain and dysphagia. Typical radiographic findings are ligament ossification, para-articular osteophytosis, and bone production at sites of tendon and ligment attachment in spinal and extraspinal locations. The extraspinal roentgenographic manifestations are so characteristic that when present, they allow the diagnosis of spinal ankylosing hyperostosis to be suggested, even in the absence of axial radiographs.

Roentgen features of the rheumatoid mid- and hindfoot.

The roentgen features of rheumatoid involvement of the mid- and hindfoot are analyzed utilizing anatomic and pathologic material from "control" and rheumatoid cadavers and a detailed radiographic study of a rheumatoid population. Characteristic findings include diffuse abnormalities predilecting the calcaneus, talocalcaneonavicular and tarsometatarsal joints with joint space narrowing, bony fusion and reactive sclerosis. Rheumatoid localization in the mid- and hindfoot is not unusual, particularly in long-standing disease, and is almost universally associated with metatarsophalangeal alterations.

Postoperative heterotopic ossification in patients with ankylosing hyperostosis on the spine (Forestier's disease).

Heterotopic ossification following hip surgery occurred in three patients with ankylosing hyperostosis of the spine. No technical difficulty during surgery was encountered in these individuals. The occurrence of this postoperative complication, coupled with the appearance of bony outgrowths at sites of ligament attachment throughout the axial and extra-axial skeleton in patients with ankylosing hyperostosis of the spine, suggests the presence of an underlying ossifying diathesis, diffuse idiopathic skeletal hyperostosis (DISH). A significant number of patients with DISH possess the second segregant series antigen, HLA-B27, a feature they share with individuals with other arthropathies characterized by abundant ossification; this gene may be closely related to one which influences bone formation. The possible association of postoperative heterotopic ossification and ankylosing hyperostosis of the spine indicates that a radiographic examination of the vertebral column in patients undergoing hip surgery may be a useful screening procedure.

Fistulization of rheumatoid joints. Spectrum of identifiable syndromes.

Eight patients with rheumatoid arthritis developed cutaneous fistulae adjacent to affected joints. Rheumatoid factor was positive in eight patients; subcutaneous nodules were noted in seven. Two patients had features of rheumatoid vasculitis. A spectrum of syndrome characterized by cutaneous fistulae was observed. Three patients showed classical fistulous rheumatism. Four patients developed septic arthritis which subsequently fistulized; in two, infection was associated with total joint replacement. One patient showed a cutaneous sinus accompanying a large calf cyst. A variety of diagnoses must be considered when cutaneous fistulae appear near joints in patients with rheumatoid arthritis.
