Failures of DIFFERENTIATION (Swanson 2)‣What is clinodactyly?Deformity in Little finger (radial angulation)resulting from abnormal epiphysis of the middle phalanx‣Differentiate from Kirner's deformity?Kirner's deformity is a radial and volar curvature of the distal phalanx of the 5th finger. Bilteral involvement more common than unilateral.Rare and unknown condition‣Associated syndromes?25% downs syndrome‣Classification of Clinodactyly?1 = minor angulation2 = minor angulation and short3 = Delta phalanx with C-shape physis‣Management of clinodactyly?Non op mostlyOpIndications – functional deficits such that it encroaches neighbouring fingerPhalanx opening wege osteotomy + bone excision (closing lead to more shortening)‣What is camptodactyly?Non hereditatory atraumatic flexion deformity of the fingers at the PIPJ‣Management?Splinting usually good resultsif fail ➔ surgical correction with releae of volar contracture
