Classification	ICD-10: Q77.8 OMIM: 277590 MeSH: D054217
External resources

Weismann-Netter–Stuhl syndrome is a rare genetic disorder characterized by abnormalities in bone development, particularly affecting the tibia and fibula. This condition is also known as "tibial diaphyseal dysplasia" and is primarily inherited in an autosomal dominant pattern.

Presentation

Individuals with Weismann-Netter–Stuhl syndrome typically present with short stature and bowing of the legs. The tibia and fibula are often affected, leading to a distinctive anterior bowing. This condition may be apparent at birth or develop during early childhood.

Skeletal Abnormalities

The primary skeletal abnormalities in Weismann-Netter–Stuhl syndrome include:

• Anterior bowing of the tibia and fibula
• Shortening of the lower limbs
• Thickening of the cortical bone

These skeletal changes can lead to difficulties in walking and may require orthopedic intervention.

Genetics

Weismann-Netter–Stuhl syndrome is inherited in an autosomal dominant manner, meaning that a single copy of the altered gene in each cell is sufficient to cause the disorder. However, the specific gene responsible for this condition has not been definitively identified.

Diagnosis

Diagnosis of Weismann-Netter–Stuhl syndrome is primarily based on clinical evaluation and radiographic findings. X-rays typically reveal the characteristic bowing and thickening of the tibia and fibula. Genetic testing may be used to confirm the diagnosis, although the specific genetic mutation is not always identified.

Management

Management of Weismann-Netter–Stuhl syndrome focuses on addressing the orthopedic complications associated with the condition. This may include:

• Physical therapy to improve mobility
• Orthopedic surgery to correct severe bowing or deformities
• Regular monitoring of growth and development

Prognosis

The prognosis for individuals with Weismann-Netter–Stuhl syndrome varies depending on the severity of the skeletal abnormalities. With appropriate management, many individuals can lead relatively normal lives, although they may experience some limitations in physical activities.
