Mild arthritis/arthralgia is the most frequent extraintestinal manifestation in inflammatory bowel disease (IBD) and has been reported to occur in 10-35% of patients in different studies. A classification of peripheral arthropathy in relation to inflammatory bowel disease has recently been proposed. Type 1: pauciarticular, asymmetrical, preferably large joints, and related to IBD activity. Type 2: polyarticular, symmetrical, preferably small joints, and occurring independently of IBD activity. While this classification requires the presence of synovitis, arthralgia without swelling or other objective signs are of equal frequency but are not covered by this system. In this issue of the journal, Thomas et al. report a prospective study, incorporating strict endoscopic and histological criteria for pouchitis, which elucidates the correlation to arthropathy. Both pouchitis and symptoms of the joints occurred more frequently in ulcerative colitis patients than in patients with familial polyposis. Surprisingly, arthropathy was not more frequent among patients with pouchitis than among patients without pouchitis in this study. Extraintestinal manifestations of the joints are thus not likely to be a reactive arthritis secondary to pouchitis, which would have been an obvious explanation. Preoperative occurrence of extraintestinal manifestations from the joints does not seem to be predictive for the outcome of an ileo-anal pouch anastomosis and especially development of pouchitis. The arthritic symptoms were generally mild and not disabling.

Ankylosing spondylitis (AS) is the prototypical form of the spondyloarthropathies, which at a prevalence of 2 % is among the most frequent rheumatic diseases. Spondyloarthropathy comprises the following five disorders: AS, reactive arthritis, psoriatic arthritis, enteropathic arthritis in Crohn's disease, and ulcerosing colitis as well as undifferentiated spondyloarthropathy. In 99 % of the patients with AS initial abnormal findings affect the sacroiliac joints. The radiographic changes required for diagnosing AS occur as late as 5 - 9 years after the onset of clinical symptoms. MRI of the sacroiliac joints reliably demonstrates both chronic inflammatory changes (erosions, sclerotic changes, bone bridges) and acute inflammatory changes (synovitis, capsulitis, osteitis) and allows for grading the chronicity and acuity of such changes. Enthesitis of the interosseous ligaments of the retroarticular space is a manifestation of AS. Spondylodiscitis (Andersson 1937) may occur as an inflammatory or non-inflammatory process (transdiscal fatigue fracture). Inflammations of the facet and costospinal joints developing into ankylosis are typical of AS. Changes of the vertebral bodies occur as anterior (Romanus 1952), posterior, and marginal spondylitis. All forms of spondyloarthropathies are furthermore characterized by asymmetrical synovitis of the large joints, particularly of the legs (gonarthritis, coxitis, tarsitis, peripheral oligoarthritis), rheumatic fibroosteitis (pelvic enthesitis, rheumatic calcaneopathy), and peri- and synchondritis of the pubic symphisis and sternal synchondrosis. Since early inflammatory changes of the spinal column and of the extravertebral localizations in AS are demonstrated by MRI before they become apparent on radiographs, and thereby the diagnostic gap could be closed, the early use of MRI for diagnostic and follow-up is commendable, when new therapeutical options like the so-called "biologicals" are employed.

Peripheral involvement of the joints, including pauciarticular, asymmetrical, transitory and migrating synovitis and enthesiopathy, is observed in 10-20% of affected inflammatory bowel disease patients. Recurrence is common and frequently coincides with a flare-up of intestinal disease. The true prevalence of axial involvement is less well established. Sacroiliitis is a hallmark of spondylitis, but is under-reported due to its insidious onset and sometimes asymptomatic nature. Radiographic evidence of sacroiliitis is present in about 20-25% of patients. Ankylosing spondylitis, as defined by the Rome criteria, is present in 3-10% of inflammatory bowel disease patients, and is thought to have a different genetic predisposition in these patients compared with 'classic' ankylosing spondylitis: whereas the human leucocyte antigen B27 phenotype is present in 90% of patients with 'classic' ankylosing spondylitis, the prevalence decreases to only 30% in patients with ankylosing spondylitis secondary to Crohn's disease. Polymorphisms involving CARD15 appear to be a possible genetic trigger: 78% of patients with Crohn's disease and symptomatic or asymptomatic sacroiliitis carry at least one mutation, compared with only 48% of control Crohn's disease patients. Moreover, in other forms of spondyloarthropathy, a similar association has been reported: 42% of patients with spondyloarthropathy and associated asymptomatic chronic gut inflammation, who are considered likely to develop Crohn's disease and ankylosing spondylitis, are carriers of at least one CARD15 mutation, compared with only 7% of patients with normal histology. In addition to genetic markers, clinical features support the relationship between gut and joint pathophysiology. In cases of spondyloarthropathy, a very rapid, substantial and sustained improvement in symptoms has been reported following treatment with infliximab, suggesting an essential role for tumour necrosis factor-alpha in spondyloarthropathy, similar to that observed in Crohn's disease.

Psoriasis is a chronic, relapsing, inflammatory skin disorder with a strong genetic basis. Five patterns of psoriatic arthritis have been identified: asymmetrical oligoarticular arthritis, symmetrical polyarthritis, distal interphalangeal arthropathy, arthritis mutilans and spondylitis with or without sacroiliitis. Extra-articular disease is uncommon. We report a rare case of an inflammatory posterior interosseus nerve palsy in a patient with known psoriatic arthropathy, where investigation warranted medical treatment over a surgical approach. The commonest cause of posterior interosseus nerve palsy is entrapment at the proximal forearm. Other possible aetiologies include extension of elbow synovitis as described in rheumatoid arthritis, trauma eg. Monteggia fractures, tumours and iatrogenic injuries. We discuss the diagnostic dilemma and the management issues for upper limb surgeons.
