Das Leben ist es wert.

I. Failure of formation of parts (arrest of development) A. Transverse deficiencies I. Amputations: arm, forearm, wrist, hand, digits B. Longitudinal deficiencies 1. Phocomelia: complete, proximal, distal 2. Radial deficiencies (radial club hand) 3. Central deficiencies (cleft hand) 4. Ulnar deficiencies (ulnar club hand) 5. Hypoplastic digits

II. Failure of differentiation (separation) of parts A. Synostosis: elbow, forearm, wrist, metacarpals, phalanges B. Radial head dislocation C. Symphalangism D. Syndactyly 1. Simple 2. Complex 3. Associated syndrome E. Contracture 1. Soft tissue a) Arthrogryposis b) Pterygium cubitale c) Trigger digit d) Absent extensor tendons e) Hypoplastic thumb f ) Thumb-clutched hand g) Camptodactyly h) Windblown hand 2. Skeletal a) Clinodactyly b) Kirner´s deformity c) Delta bone

III. Duplication A. Thump (preaxial) polydactyly B. Triphalangism /hyperphalangism C. Finger polydactyly 1. Central polydactyly (polysyndactyly) 2. Postaxial polydactyly D. Mirror Hand 1. (Ulnar dimelia) IV. Overgrowth-all or portions of upper limb A. Macrodactyly V. UndergrowthVI. Congenital constriction band syndrome VII. Generalized skeletal abnormalities A. Madelung´s deformity _________________________________________Modified from Swanson AB: A classification for congenital limp malformations: J Hand Surg 1:8-22,1976.
