1/122. Anteroposterior atlantoaxial subluxation in cervical spine osteoarthritis: case reports and review of the literature.Nontraumatic anteroposterior atlantoaxial subluxation (AAS) has been described in several rheumatic or inherited disorders, especially rheumatoid arthritis and to a lesser extent the inflammatory spondyloarthropathies. We describe AAS secondary to osteoarthritis (OA) of the cervical spine in a 76-year-old man and a 73-year-old woman with severe cervical OA, symptomatic C1-C2 facet joints, and signs of generalized OA. Only 6 similar cases exist in the literature. OA should be added to the causes of AAS, and conversely AAS should be assessed in cases with severe OA of the upper cervical spine.- - - - - - - - - - ranking = 1keywords = rheumatoid arthritis, arthritis (Clic here for more details about this article) |
2/122. Spontaneous regression of periodontoid pannus mass in psoriatic atlantoaxial subluxation. Case report.STUDY DESIGN: A case report of a 41-year-old man with psoriasis who had cervical myelopathy caused by atlantoaxial subluxation and periodontoid pannus mass. OBJECTIVE: To describe the possible mechanism underlying the periodontoid pannus formation and the optimal treatment for such cases. SUMMARY OF BACKGROUND DATA: Atlantoaxial subluxation causing spinal cord compression at the craniocervical junction may develop in patients with rheumatoid or psoriatic arthritis. Periodontoid pannus formation plays an important role in compromising the anteroposterior diameter of the spinal canal and in causing neurologic deficits. Transoral transpharyngeal excision of the pannus is sometimes thought necessary for anterior decompression of the spinal cord. Spontaneous resolution of the periodontoid pannus after posterior atlantoaxial fusion and fixation has been documented in rheumatoid arthritis, but not in psoriatic arthritis. methods: The patient underwent posterior atlantoaxial fusion and Halifax fixation. RESULTS: The patient experienced clinical improvement. Regression of the periodontoid pannus mass was observed on magnetic resonance imaging. CONCLUSIONS: Posterior fusion and instrumentation resulted in spontaneous regression of the pannus mass and symptomatic relief. This report provides evidence that atlantoaxial instability may be the sine qua non for the formation of periodontoid pannus, and that amelioration of such instability leads to spontaneous resolution of the pannus mass.- - - - - - - - - - ranking = 0.61599863429267keywords = rheumatoid arthritis, arthritis (Clic here for more details about this article) |
3/122. Successful conservative treatment of rheumatoid subaxial subluxation resulting in improvement of myelopathy, reduction of subluxation, and stabilisation of the cervical spine. A report of two cases.OBJECTIVE: To report the efficacy of conservative treatment with cervical traction and immobilisation with a Halo vest, in two consecutive rheumatoid arthritis patients with progressive cervical myelopathy caused by subaxial subluxation. methods: Description of neurological symptoms and signs and findings in plain radiography (PR) and magnetic resonance imaging (MRI) of the cervical spine before and after treatment of the subaxial subluxation by traction and immobilisation with a Halo vest during four months. RESULTS: During four months of traction and immobilisation neurological examination showed a considerable improvement of the signs and symptoms of cervical myelopathy. Afterwards PR and MRI of the cervical spine showed reduction of the subaxial subluxation. Eventually firm stabilisation was obtained in both patients without surgery of the cervical spine. CONCLUSION: Cervical traction and immobilisation with a Halo vest can be considered as an independent conservative treatment in rheumatoid arthritis patients with cervical myelopathy caused by subaxial subluxation.- - - - - - - - - - ranking = 0.71999544764225keywords = rheumatoid arthritis, arthritis (Clic here for more details about this article) |
4/122. Lisfranc's or tarsometatarsal fracture-dislocation.Lisfranc's injuries are one of the most commonly missed fractures in a multitrauma patient. Failure to recognize and treat such an injury can lead to acute (e.g., compartment syndrome of the foot) and chronic problems (e.g., arthritis). A list of reminders is included to help with the recognition and treatment of Lisfranc's injuries (Table 1).- - - - - - - - - - ranking = 0.12800045523578keywords = arthritis (Clic here for more details about this article) |
5/122. Total knee arthroplasty in an adult with congenital dislocation of the patella.This article reports the use of total knee arthroplasty with release of the lateral retinaculum, proximal extensor mechanism realignment, and patellar resurfacing as a valid treatment option for adult patients with congenital dislocation of the patella who have absence of the femoral sulcus and associated osteoarthritis. The patient presented in this case report had improvement of his knee Society knee score and function score from preoperative levels of 8 and 45 to 77 and 80 postoperatively.- - - - - - - - - - ranking = 0.12800045523578keywords = arthritis (Clic here for more details about this article) |
6/122. Sigmoid notch osteoplasty for chronic volar instability of the distal radioulnar joint: a case report.Chronic recurrent volar dislocation of the distal radioulnar joint is a rare condition for which many operative procedures have been described. We describe a case of painful dislocation on supination. Investigation of the distal radioulnar joint revealed the absence of degenerative arthritis and a flat sigmoid notch that permitted dislocation. The case was successfully treated by osteoplasty of the volar lip of the sigmoid notch to create a buttress that prevented volar dislocation.- - - - - - - - - - ranking = 0.12800045523578keywords = arthritis (Clic here for more details about this article) |
7/122. Marginal plafond impaction in association with supination-adduction ankle fractures: a report of eight cases.In five years, approximately 800 ankle fractures were seen at the authors' institution, forty-four (5 percent) of which were of the supination-adduction pattern. Nineteen of these injuries had displaced vertical medial malleolus fractures, of which eight (42 percent) showed marginal impaction of the tibial plafond. All eight patients underwent open reduction and internal fixation with elevation of the impacted articular component and had good to excellent functional outcome with no arthritis on radiograph at the time of the most recent follow-up. The index of suspicion of marginal impaction of the tibial plafond should be high when treating supination-adduction pattern ankle fractures with displaced medial malleolus.- - - - - - - - - - ranking = 0.12800045523578keywords = arthritis (Clic here for more details about this article) |
8/122. Computer-assisted Magerl's transarticular screw fixation for atlantoaxial subluxation.We report two patients with rheumatoid arthritis in whom posterior atlantoaxial fixation was carried out using transarticular screws with computer assistance. Two bilateral transarticular screws were inserted in one patient; however, in the other patient, only a unilateral screw was used, because computerized images showed that the vertebral artery at the other side was placed too medially to allow insertion of the screw. Neither of these patients had any neurovascular complications after surgery. Computer-assisted surgery is useful for avoiding neurovascular complications with transarticular screw fixation of C1-2.- - - - - - - - - - ranking = 0.35999772382112keywords = rheumatoid arthritis, arthritis (Clic here for more details about this article) |
9/122. The posteromedial process fracture of the talus: a case report.Injuries to the ankle tend to be some of the most common injuries seen in practice. Of these ankle injuries, fractures of the posteromedial process of the talus are often misdiagnosed as ankle sprains because of poor visualization on routine ankle radiographs. The examining physician must have a heightened awareness of this injury to accurately diagnose and treat this fracture. Proper treatment could help to lessen the possibility of post-traumatic arthritis to the ankle and subtalar joints. The authors present a case of a fracture of the posteromedial process of the talus, after a medial subtalar dislocation, treated with open reduction and internal fixation with bioabsorbable pins.- - - - - - - - - - ranking = 0.12800045523578keywords = arthritis (Clic here for more details about this article) |
10/122. syringomyelia caused by loosening of multistrand cables following C1-2 Brooks-type fusion in the rheumatoid cervical spine. Case report.The authors report a very rare case of syringomyelia caused by loosening of multistrand cable wires following C1-2 Brooks-type fusion in a 36-year-old woman with a 13-year history of rheumatoid arthritis (RA). The syrinx vanished immediately after removal of the cables, and 2 years later no recurrence of symptoms or deterioration has occurred. The authors contend that multistrand titanium cables should not be used to fix a graft-assisted C1-2 construct in patients with RA, although this material is good for fixing rods. The phenomenon observed in this case adds to our understanding of the pathogenesis of noncommunicating syringomyelia.- - - - - - - - - - ranking = 0.35999772382112keywords = rheumatoid arthritis, arthritis (Clic here for more details about this article) |
