Anterior atlantoaxial subluxation is considered an uncommon feature of ankylosing spondylitis (AS). Six of 17 (35%) patients with spondylitis and peripheral arthritis had anterior atlantoaxial subluxation compared to none in a control group of 21 patients with AS with exclusively axial involvement (p = 0.009). Most of our patients with peripheral arthritis, with and without anterior atlantoaxial subluxation, also had an associated disorder (psoriasis, Reiter's or inflammatory bowel disease). Other features of radiologic cervical spine involvement (syndesmophytes and ankylosis) were equally present in all groups of patients (axial and peripheral arthritis, with or without subluxation). We conclude that anterior atlantoaxial subluxation is a frequent complication of the spondyloarthropathies in the presence of persistent peripheral disease and can occur in up to one third of these patients.

Radiologic examination of 43 patients revealed 47 lesions of a type which we have termed hemispherical spondylosclerosis (HSS). This term describes and includes the following essential and possible radiologic findings of the disease: 1) Hemispherical (or "dome-" or "helmet-shaped") sclerosis of the vertebra above the intervertebral disk. Thus it is a supradiscal HSS. 2) One or more small erosions of the inferior end plate of the vertebra involved. 3) Periosteal apposition on the anterior border of the vertebra along the length of the sclerosis. 4) New bone formation on the inferior end plate. 5) Anterior vertebral osteophytes. 6) Narrowing of the disk space below the affected vertebra. HSS occurs not only as a sequel of degenerative disk disease, but also in bacterial (tuberculous and non-tuberculous) spondylitis, ankylosing spondylitis, osteoid osteoma, and metastases of neoplasms. The differential diagnosis between inflammatory and noninflammatory pathogenesis and etiology of HSS is described. The characteristic shape of HSS, its sites of predilection (14 greater than L5 greater than L3), and the preponderance of female sufferers from this painful condition are due to factors which, as yet, remain unknown.

We have described clinical features of 53 cases with pustulotic arthro-osteitis. Anterior chest wall symptoms such as intersterno-costoclavicular or manubriosternal lesions were observed in all of 53 cases. Spondylitis or spondylodiscitis was found in 18 cases. Sacroiliitis resembling ankylosing spondylitis was seen in 7 cases. Peripheral inflammatory arthritis was seen in 14 cases, which were of nonerosive, of oligoarthritis type, and cured within 1 to 2 months, leaving no residue. HLA B27 was never found, and RAW factor was negative. Histological examinations revealed nonspecific chronic inflammation of bone and soft tissue. Pustulotic arthro-osteitis is apparently distinct from known rheumatic diseases such as rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, and Reiter's disease. We have proposed that this condition should be classified as a member of the "seronegative spondylo-arthritis' group as designated by Wright and Moll.

We conducted a retrospective analysis of 1122 patients with endogenous uveitis treated at the University Eye Clinic in Turku during the years 1980-1982 and 1988. Of the 1122 patients 568 were men and 554 women; 1034 (92.2%) had anterior uveitis, 15 (1.3%) intermediate uveitis, 64 (5.7%) posterior uveitis and 9(0.8%) panuveitis; 867 (77.3%) were unilateral and 255 bilateral; 789 of 1067 cases (73.9%) were of sudden onset and 278 of insidious onset; 808 of 1102 cases (73.3%) were of short duration and 294 of long duration; and 519 (46.3%) single and 603 repeated. In this study uveitis occurred significantly more often (44.2%) in the age group 20-39 years than in other age groups (p < 0.00001). Anterior and posterior uveitis were more often unilateral than bilateral (p < 0.0005) and of sudden onset than of insidious onset (p < 0.00008). Acute anterior uveitis was the most common uveitic entity and accounted for 745 cases (66.4%). Acute anterior uveitis associated with ankylosing spondylitis was the single most frequently seen diagnostic group including 144 cases (12.8%) with a statistically significant male predominance (p < 0.00001).

In an effort to determine trends in surgery of cervical spine disorders and the incidence of complications resulting from this treatment, a mechanism was established for the collection and analysis of multicenter data on an every-5-year basis. This data collection technique allowed the tracking of trends in the treatment for specific diagnoses and determination of complication rates for individual procedures. We present the results occurring in 4,589 patients operated on by 35 surgeons per year between 1989 and 1993. Principal diagnoses included spondylosis, herniated nucleus pulposus, trauma, rheumatoid arthritis, ankylosing spondylitis, ossification of the posterior longitudinal ligament, and tumor. Surgical procedures included anterior cervical discectomy, anterior cervical discectomy and fusion, corpectomy, laminectomies, posterior arthrodesis, laminoplasty, and cervical plating. Complications reported include: bone graft failure, cerebrospinal fluid leak, recurrent laryngeal nerve injury, root injury, quadriplegia, and death. The yearly percentages of each diagnosis have been roughly stable for each year of the study. However, the operative procedures revealed some interesting trends. There was no overall trend with regard to complications over time, and the overall complication risk was approximately 5%. The present data confirm that cervical spine disease is primarily degenerative or discogenic. However, trauma still remains a major part of the practice, accounting for upwards of 17% of reported cases. Anterior procedures were twice as common as posterior ones. The risk of operative complications remains small yet significant.

The onset of ankylosing spondylitis is usually characterized by lower back pain and stiffness in young adults; early diagnosis is not easy, but the disease is generally identified within a few years of onset. Anterior atlantoaxial subluxation may occur in the late stage of ankylosing spondylitis, but early spontaneous subluxation is rarely seen. We present a case of ankylosing spondylitis with an initial symptom of neck pain, rather than lower back pain, due to spontaneous anterior atlantoaxial subluxation. After medical and surgical intervention, except for limited range of motion, the patient experienced neither neck pain nor weakness of his left limbs during the next 8 mo of follow-up.

Forestier's disease now called DISH (diffuse idiopathic skeletal hyperostosis) is a non inflammatory enthesopathy ossifying the anterolateral spine and sparing the disc and joint space in elderly men, mostly at thoracic levels. Radiology performed for minor trauma or to explore a stiff neck provides the diagnosis. The main differential diagnosis is ankylosing spondylitis presenting an inflammatory profile as well as previously existing alterations of the sacroiliac joint. Retinoic acid treatment or ossification of the posterior longitudinal ligament should also be discussed. Dysphagia is the most frequent symptom, but neurological signs are rarely observed. We report a case observed at the cervical level. Anterior decompression and cage-fusion was indicated. Ongoing hyperostosis was also documented. Surgery in DISH is mainly indicated for dysphagia and rarely after cervical trauma. Of note are associated lesions such as OPLL (ossification of the posterior longitudinal ligament) or synovial cysts responsible for the exceptional and severe myelopathy presentation. The neurosurgical community should become better aware of Forestier's disease.

Anterior cervical spine fusion and stabilization is a well-recognized procedure for a number of cervical spine disorders. Unfortunately, the complex anatomy of the cervical spine means that these procedures are not without complications. Pharyngo-oesophageal perforation is a rare but potentially life-threatening complication of cervical spine surgery and may present intra-operatively, in the immediate post-operative period or many years later. We present the case of a gentleman with ankylosing spondylitis who presented with a pharyngeal perforation and fistula five years after cervical spine surgery.

We retrospectively reviewed 54 patients (92 hips) who underwent cementless total hip arthroplasty for bony ankylosis in ankylosing spondylitis between September 1988 and 2002. The mean age of the patients was 25.5 years. The mean duration of follow-up was 8.5 years. The average preoperative Harris Hip Score of 49.5 improved to 82.6 postoperatively. Postoperatively, 10 hips had mild to moderate pain. Anterior dislocation occurred in 4 (4.3%) hips, and sciatic nerve palsy in 1 (1.1%) hip. Heterotopic ossification was seen in 12 patients; reankylosis rate was 0%. Thirteen (14%) arthroplasties were revised because of aseptic loosening. Kaplan-Meier survivorship analysis with revision as end point revealed 98.8% survival at 5 years and 85.8% survival at 8.5 years follow-up.

In this study, the relation between osteoporosis and vitamin D and the disease activity in patients with ankylosing spondylitis (AS) was investigated. A hundred patients with AS and 58 healthy individuals were included in the study. In addition to the routine blood and urine tests, serum 25-(OH)D3, parathormone (PTH), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), total calcium, ionized calcium, and phosphorous levels of all participants were also measured. Bone mineral density (BMD) measurements were performed at the anterior-posterior and lateral lumbar and femur regions. Anterior-posterior and lateral thoracic and lumbosacral radiography was performed on all participants. The disease activity was evaluated by Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), functional status by Bath Ankylosing Spondylitis Functional Index (BASFI), and mobility by Bath Ankylosing Spondylitis Metrology Index (BASMI). In the patient group, BMD values obtained from the lateral lumbar and femur regions and serum vitamin D levels were lower than the control group. A negative relation was determined between the lateral lumbar BMD values and ESR, CRP, and BASDAI scores of patients with AS. The ESR, CRP levels, and BASMI scores of the AS patients with osteoporosis were significantly higher, when compared to patients without osteoporosis. The negative correlation between serum 25-(OH)D3 level and ESR, CRP levels did not reach a statistically significant level in patients with AS; the positive correlation between PTH levels and ESR, and the negative correlation between CRP and BASDAI also did not reach a statistically significant level. Vitamin D deficiency in AS may indirectly lead to osteoporosis by causing an increase in the inflammatory activity. The present authors believe that it would be beneficial to monitorize vitamin D levels together with BMD measurements in order to determine the patients under osteoporosis risk.
