[0] Retinacular Test [1] Position the patient with the forearm in pronation and the hand relaxed on the table surface. [3] To conduct the test, hold the P.I.P. joint in full extension as you try to move the D.I.P. joint into flexion. If the joint does not flex, limitation is due to either contracture of the joint capsule or to retinacular tightness. To distinguish between these two, flex the proximal interphalangeal joint slightly to relax the retinaculum. If the distal interphalangeal joint then flexes, the retinacular ligaments are tight. If the joint does not flex, the distal interphalangeal joint capsule is probably contracted. [2] 
Verifies the tightness of the retinacular ligaments.
