OBJECTIVES: To determine the accuracy of ultrasonography (US) for bone erosion detection in different areas of rheumatoid arthritis (RA) metacarpophalangeal (MCP) joints with multislice CT as the reference method. Second, to establish the necessary bone volume loss on CT for US to reliably detect it as an erosion, and finally ...

Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by bone erosion and cartilage destruction in the joints. Many of the conventional anti-arthritic drugs are effective in suppressing inflammation, but they do not offer protection against bone damage. Furthermore, the prolonged use of these drugs is associated with severe adverse ...

Reconstruction of a distally ruptured extensor pollicis longus tendon in the rheumatoid patient generally involves a tendon transfer or intercalary graft. We present an alternative technique using the radial half of the extensor carpi radialis longus as a turn-over graft. Using the turn-over technique with a half-slip of the extensor ...

ABSTRACT: There are no reports of atraumatic hip subluxation and dislocation in the adult patient with rheumatoid arthritis (RA). This rare phenomenon is most prevalent in patients with congenital hip dislocation, von Recklinghausen disease, tumor infiltration, connective tissue disorders, and juvenile rheumatoid arthritis. We report an acute atraumatic dislocation of ...

Congenital cholesteatomas can occur within the temporal bone. Congenital cholesteatoma of the external auditory canal is rare. Generally, it appears in the canal floor. ...

Traumatic hip fracture-dislocations are serious injuries and may lead to long-term disability even if managed correctly. Standard radiographic procedures have a limited value in fully evaluating a traumatized hip. Multidetector computed tomography is, today, a valuable diagnostic tool for the evaluation of patients with traumatic hip fracture-dislocation. This article reviews ...

Previous studies show the shape of the femur in developmental dislocation of the hip (DDH) becomes more abnormal with increasing subluxation. Two kinds of high dislocations associated with DDH have been observed in clinical practice, one with (Type C1) and one without (Type C2) a false acetabulum. The presence or ...

A 15-year-old boy with neurofibromatosis type 1 developed habitual dislocation of the right hip. No intraarticular pathology could be found in imaging studies. The dislocation became fixed during the follow-up.

A simple hip dislocation is one without fracture of the proximal femur or acetabulum. Complex fracture-dislocations involve the acetabulum, femoral head, or femoral neck. The incidence of posttraumatic arthritis is much lower in simple dislocations than in fracture-dislocations. The most common mechanism of injury is a high-energy motor vehicle accident, ...

Bilateral hip dislocation rarely occurs. In this paper, a case of bilateral hip dislocation associated with bilateral sciatic nerve palsy resulted from a road traffic accident is reported.

Over the past two decades antibiotic-impregnated hip spacers have become a popular procedure in the treatment of hip joint infections. Besides infection persistence and/or reinfection, major complications after hip spacer implantation include spacer fracture, -dislocation, and bone fracture. Moreover, in cases with extensive loss of femoral and/or acetabular bone alternative ...

Posterior fracture-dislocation of hip is uncommonly encountered in rugby injuries. We report such a case in an adult while playing rugby. The treating orthopaedician can be caught unaware and injuries in such sports can be potentially misdiagnosed as hip sprains. Immediate reduction of the dislocation was performed in theatres. The ...

Hip dislocations during sporting activities represent only 2%-5% of all hip dislocations. Most hip dislocations in sports can be categorised as "less complicated traumatic hip dislocations" by the Stewart-Milford classification due to the fact that minimal force is involved. The incidence of avascular necrosis of the femoral head greatly increases ...
