1/143. Wasting of the small hand muscles in upper and mid-cervical cord lesions.Four patients are described with destructive rheumatoid arthritis of the cervical spine and neurogenic wasting of forearm and hand muscles. The pathological connection is not immediately obvious, but a relationship between these two observations is described here with clinical, radiological, electrophysiological and necropsy findings. Compression of the anterior spinal artery at upper and mid-cervical levels is demonstrated to be the likely cause of changes lower in the spinal cord. These are shown to be due to the resulting ischaemia of the anterior part of the lower cervical spinal cord, with degeneration of the neurones innervating the forearm and hand muscles. These findings favour external compression of the anterior spinal artery leading to ischaemia in a watershed area as the likeliest explanation for this otherwise inappropriate and bizarre phenomenon.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
2/143. Failure of the hinge mechanism of a trispherical total wrist arthroplasty: a case report and review of the literature.We report a patient with rheumatoid arthritis who developed late catastrophic failure of the hinge mechanism of her trispherical total wrist arthroplasty. This was associated with synovitis secondary to wear debris from titanium, cement, and polyethylene which produced exuberant flexor and extensor tendon synovitis and median nerve compression.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
3/143. Lumbar intraspinal synovial cysts of different etiologies: diagnosis by CT and MR imaging.Intraspinal synovial cysts arises from a facet joint and may cause radicular symptoms due to nerve root compression. In the present study, three surgically and histologically proved cases of synovial cyst of the lumbar spine with different etiology are described. The purpose of this report is to illustrate the imaging features of various etiologies of intraspinal synovial cysts allowing a correct preoperative diagnosis. review of the literature enables us to say that to our knowledge, there is no reported article collecting the imaging findings of intraspinal synovial cysts with different etiologies. Only single cases with rheumatoid arthritic or traumatic origin have been reported to date. We believe that computed tomography and particularly magnetic resonance imaging are the methods of choice which provide the most valuable diagnostic information.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |

5/143. Pathological fracture of a lumbar vertebra caused by rheumatoid arthritis--a case report.We describe a case of rheumatoid arthritis (RA) with collapse of the L3 lumbar vertebra for which surgery was performed.

6/143. Primary resection total knee arthroplasty for complicated fracture of the distal femur with an arthritic knee joint.Treatment of fractures of the distal end of the femur in an elderly patient is difficult. If the knee joint is arthritic, the problem is even greater. The reports of two patients with rheumatoid arthritis who sustained fractures of the distal end of the femur and underwent unconventional treatment with a resection total knee arthroplasty are presented.- - - - - - - - - - ranking = 34.63180542353keywords = fracture (Clic here for more details about this article) |
7/143. A clinico-pathological study of cervical myelopathy in rheumatoid arthritis: post-mortem analysis of two cases.Two patients who developed cervical myelopathy secondary to rheumatoid arthritis were analyzed post mortem. One patient had anterior atlanto-axial subluxation (AAS) combined with subaxial subluxation (SS), and the other had vertical subluxation (VS) combined with SS. In the patient with AAS, the posterior aspect of the spinal cord demonstrated severe constriction at the C2 segment, which arose from dynamic osseous compression by the C1 posterior arch. A histological cross-section of the spinal cord at the segment was characterized by distinct necrosis in the posterior white columns and the gray matter. In the patient with VS, the upper cervical cord and medulla oblongata showed angulation over the invaginated odontoid process, whereas no significant pathological changes were observed. At the level of SS, the spinal cord was pinched and compressed between the upper corner of the vertebral body and the lower edge of the lamina. Histologically, demyelination and gliosis were observed in the posterior and lateral white columns.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
8/143. Repair of supracondylar femur fracture and unilateral knee replacement at the same surgery.In patients who are candidates for a total knee arthroplasty and suffer a periarticular fracture of the femur, the arthroplasty may be performed after bony union of the fracture or immediately, in conjunction with the fracture repair. Herein we present the case of a sixty-year-old female with rheumatoid arthritis and a supracondylar fracture of the right femur in whom total knee arthroplasty and retrograde nail insertion were addressed at one surgery; the outcome was favorable. The transverse extraarticular fracture pattern in this patient was advantageous for simultaneous procedures; had the fracture been more comminuted or intraarticular, it might not have been possible to perform both procedures at the same time.- - - - - - - - - - ranking = 57.719675705884keywords = fracture (Clic here for more details about this article) |
9/143. Posterior interosseous nerve palsy in a patient with rheumatoid synovitis of the elbow: a case report and review of the literature.A 54-year-old woman with rheumatoid arthritis developed loss of finger extension in the left hand. history, physical examination, and electromyography led to the diagnosis of posterior interosseous nerve palsy secondary to synovitis of the elbow. Anterior decompression and synovectomy resulted in a complete recovery. A literature review describes similar cases and compares outcomes.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
10/143. Early experience with total knee replacement.This paper presents a review of two years' experience with the geometric total knee replacement. The results of 23 arthroplasties in 22 patients are discussed. Relief of pain was consistent and dramatic, movement was increased postoperatively in only three patients, but imporvement in overall function occurred in 20 of the 22 patients. There was one failure requiring arthrodesis. In this patient, six months after surgery the medial tibial condyle collapsed and the polyethylene tibial component fractured. This complication has not been reported before. Early results are encouraging. Total knee joint replacement is a useful procedure in advanced arthritis when arthrodesis is the only alternative.- - - - - - - - - - ranking = 5.7719675705884keywords = fracture (Clic here for more details about this article) |
