Clinodactyly, Camptodactyly, Kirner's Deformity, and Other Crooked Fingers

Reverse Kirner's Deformity: Case Report

“…6 It has been reported to occur in association with malformation syndromes such as Down, Turner, Silver, Cornelia de Lange, or with musculoskeletal abnormalities such as kyphoscoliosis, genu valgum, radial metaphyseal deformity, and pes cavus. 1,[7][8][9][10][11][12][13][14] The deformity is usually of no major functional importance, but the bowing can affect the performance of skilled tasks involving the little finger such as playing the piano. 15 Radiologically, there is a 10°to 50°bowing of the diaphysis only, in the radial and volar directions.…”

Lethal and non‐lethal diastrophic dysplasia A study of 14 Swedish cases

“…This seemed to be the major reason for abduction of the thumb, in addition to general laxity of the joints, in five of our patients. LBD has previously occasionally been seen in DD (Jaeger & Refior 1971, Taybi 1963, Stover et al 1963, Holt-Oram's syndrome (Poznanski et al 1969), Rubinstein-Taybi's syndrome (Ru-binstein 1969, Poznanski et al 1971 and achondrocephalopolysyndactyly (Lenz 1957, Poznanski et al 1971, as is apparent from radiographs in these publications.…”

Kirner's Deformity:Juvenile Spontaneous Incurving of the Terminal Phalanx of the Fifth Finger

“…Differentiation between Kirner's Deformity and genuine clinodactyly (radial deviation) is important, the latter having more frequently a familial occurrence and being characterized by a normal bone structure without any periarticular swelling (Poznanski et al 1969). Exact radiograms are of importance in the differentiation.…”

“…Several synonyms have been used: Osteomalacie der Kleinfingerendephalange (Schmid 1957), Dystelephalangy (Poznanski et al 1969), The clinical and radiological features of two additional cases are presented, bringing the published number to 44.…”
