Disproportionate moderate dwarfism with Madelung wrist deformity and multiple skeletal deformities.

Lamy Bienenfeld Syndrome; Lery-Weill Dyschondrosteosis Syndrome.

First described by A. Léri and J.A. Weill in 1929.

Very rare.

Pseudoautosomal dominant (mutation in the pseudoautosomal genes SHOX or SHOXY, located on Ypter-p11.2, Xpter-p22.32).

Disease characterized by bowed radius and ulna, with small stature mainly from mesomelic origin. Can be evocated at the end of fetal growth. Predominant and more severe in female (female-to-male ratio = 4:1).

Stature is short and disproportionate (adult height 135 cm [53.1 inches]). Multiple skeletal deformities are observed. Radiologically the bones present cone epiphyses, enlarged diaphysis, metaphyseal anomaly, and multiple exostoses. Fingers and toes are abnormal. Superior limb anomalies include mesomelia, increased carrying angle, limited elbow mobility, dorsal-limited wrist mobility, subluxation of ulna, Madelung wrist deformity (occurring after 10 years and described as a displacement of the hand to the radial side as the result of dorsolateral distortion of the lower end of the radius because of relative overgrowth of the ulna). Inferior limb can present coxa vara, hip and pelvis anomalies, abnormal femur and patella, genu varum, flat foot that restricts joint mobility. Scoliosis is frequent. The face presents with a broad nose, depressed nasal bridge, and flat occiput brachycephaly.

Although there are multiple skeletal deformities, there are no indications that a difficult airway must be expected. However, it is recommended to assess carefully this aspect.

Consider chronologic age and not physical stature to determine the airway size. Careful intraoperative positioning is difficult but necessary because of deformations. Regional anesthesia is not contraindicated but can be difficult because of skeletal anomalies.

No known pharmacological implications.

Arkless-Graham Syndrome: Characterized by short hands and feet, stubby fingers and toes, broad short nails, flat nasal bridge, underdeveloped jaw, improper alignment of the teeth, widely spaced eyes, mental retardation, and deformity of the bones in the arms, legs, and elbows. It is inherited as an autosomal dominant trait. Females are affected twice as often as males.

Ellis-Van Creveld Syndrome: Characterized by short limb dwarfism, polydactyly, abnormal fingernails, and congenital heart defects. It is a form of ectodermal dysplasia that involves the skin, hair, teeth, and nails. It is inherited as an autosomal recessive trait.

Madelung Deformity: Results from partial dislocation of the bones of the forearm because of trauma or infection. Short stature is not involved.

Langer Mesomelic Dysplasia Type: Affects males and females equally and is inherited as an autosomal recessive trait. Clinical features include typically short, thick, curved bones of the radius and tibia. Other features include restricted elbow and forearm movement, underdeveloped jaw, and abnormal degree of forward curvature of the lower back.
