It includes recommendations on the management of patients with active PsA that is defined by the patients' self-report and judged by the examining clinician to be caused by PsA, based on the on the presence of at least one of the following: actively inflamed joints; dactylitis; enthesitis; axial disease; active skin and/or nail involvement; and/ or extra-articular
manifestations such as uveitis or inflammatory bowel disease.
Pre-existing intra-articular joint pathology, joint stress leading to mucioid degeneration of adjacent extra-articular
connective tissue, and joint stress stimulating mucin secretion by mesenchymal cells are the most commonly warranted theories within the literature.
manifestations are also observed in AS such as neurological involvement  and heart diseases.
15 ERA patients had articular damage and 2 patients had extra-articular
damage at a median duration of disease of 5 years.
3) Inflammatory bowel disease is an extra-articular
manifestation in rheumatic diseases such as spondyloarthropathies, but only a few cases on concurrent AOSD and IBD, mainly CD, have been reported.
The earlier nomenclature Colle, Smith, Barton lead to a broader term Distal Radial Fractures DRF covers all intra and extra-articular
PVNS clinically presents as a painful soft tissue mass.
manifestations and co-morbidities along with RA lead to increased mortality2.
The investigators stated that extra-articular
fractures can be treated without additional surgery, and that intra-articular fractures should be treated surgically to prevent posttraumatic arthritis.
The synovial membrane of the joints is the main target of damage, but patients can also have involvement of extra-articular
tissues such as eyes, skin, lungs, heart, and peripheral nerves.
In the third scenario, if an extra-articular
valgus deformity exists in the tibia, an additional extra-articular
correction osteotomy may be needed besides a traditional TKA, no matter whether it is performed in one stage or two stages.
SUMMARY--The aim of the study was to assess the influence of gap shape on biomechanical results in extra-articular
distal humeral fracture: with contact on the posterior part (by anterior gap) and contact on ulnar column (by radial gap).
