Discussion affects periarticular soft tissues resulting in joint laxity with secondary dysfunction; minimal synovitis – articular cartilage is preserved; Raynaud’s phenomenon is common; diagnosis depends on positive F ANA test along with three other criteria: swollen joints nephritis pericarditis severe rash references: The 1982 revised criteria for the classification of systemic lupus erythematosus. Updating the American … Read more
– See: – Bursae of the knee: – Pigmented Villonodular synovitis – Discussion: – synovial cavity is deepest layer of joint capsule & it often has several embryological invaginations called plica that persist into adult life; – these may cuase anterior knee symptoms, – although synovium membrane is attached all around, above to articular margins … Read more
Discussion a monarticular synovial proliferative disease which is characterized by the metaplastic conversion of cartilagenous tissue to ossified loose bodies; cartilagenous or osteocartilaginous metaplasia takes place w/in the synovial membrane of joints, bursae, or tendon sheaths; seen most often in middle-aged men; pts report pain and limitation of motion; location over one-half of cases occur … Read more
– Discussion: – synovial plica are folds of embryonic remnants of synovial membrane which, in fetus, divide knee is divided into medial, lateral, & patellar compartments; – although these membranes normally degenerate by the second trimester, (allowing knee to become one cavity), incomplete membrane degeneration will lead to the formation of plica – Medial (Shelf) Plica … Read more
– See: – Phalangeal Injury – Thumb Swan Neck Deformity – Transverse Retinacular Ligament – Discussion: – deformity involves hyperextension of PIP Joint w/ flexion of DIP joint; – deformity may start at either the PIP or DIP; – at PIP joint, there … Read more
– Discussion: – anatomic variations: of tendons in 1st extensor compartment; – APL & EPB tendons may occupy separate canals, or lie together in one osseofibrous canal; – commonly there is one EPB and multiple APL; – there is separation of first extensor compartment more often in pts w/ DeQuervain’s tenosynovitis than in those w/o … Read more
– See: – Abductors of the Shoulder: – Rotator cuff; – Anatomy: – origin: medial 2/3 of supraspinatus fossa above spine of scapula; – insertion: superior surface of greater tuberosity of humerus and capsule of shoulder joint; – demensions: supraspinatus averages 25 mm wide and has … Read more
– See: proximal biceps tendonopathy – Discussion: – refers to a detachment lesion of the superior aspect of glenoid labrum, which serves as the insertion of long head of biceps; – relatively common injury in throwing atheletes, but may most commonly occur in patients who have fallen or who have received a blow on the shoulder; – references: – Kinetics … Read more
– Stage I: – represents synovitis: – synovial membrane becomes hyperemic and edematous with foci of infiltrating small lymphocytes; – joint effussions w/ high cell count (5,000 to 60,000 per mm3) – x-rays will as yet show no destructive changes, but soft tissue swelling or osteoporosis may be … Read more
