Q70.11
Webbed fingers, right hand
Clinical Classification Guidelines
Medical Intelligence & Overview
Webbed fingers, medically known as syndactyly, is a condition characterized by the skin and possibly other tissues merging two or more fingers. When webbing occurs exclusively on the right hand, it is classified under the ICD-10 code Q70.11. This congenital condition can affect one or both hands and may involve varying degrees of web formation, from simple skin bridges to complete fusion of the digits. Though primarily a structural anomaly, syndactyly can influence hand function and appearance, often prompting medical evaluation and consideration for correction.
Causes & Symptoms
Clinical Causes: Genetic factors: Syndactyly is frequently inherited in an autosomal dominant pattern, meaning only one copy of the involved gene is sufficient to cause the condition. Genetic syndromes: It may be associated with broader syndromic conditions such as Apert syndrome, Poland syndrome, or Velocardiofacial syndrome. Environmental factors: Although less common, environmental influences during pregnancy, such as exposure to certain drugs or toxins, could contribute to developmental abnormalities. Random genetic mutations: Occasionally, syndactyly results from spontaneous genetic mutations with no family history.
Key Symptoms: Presence of webbing or skin connecting the fingers on the right hand. Varying degrees of fusion: from a simple web of skin to complete bone fusion (though the latter is less common in syndactyly). Possible asymmetry if syndactyly affects only one hand or specific digits. Potential limitations in hand mobility or dexterity depending on the severity. Possible cosmetic concerns due to apparent webbing, affecting aesthetic appearance.
Diagnostic & Treatment
Diagnosis Path: Diagnosis of syndactyly is primarily clinical, based on physical examination of the hand. Healthcare providers assess the extent of webbing and any associated anomalies. Imaging studies, such as X-rays, may be employed to determine whether the bones are fused or if there are other skeletal abnormalities. In some cases, genetic testing or counseling might be recommended to investigate underlying syndromic associations or inheritance patterns.
Treatment Protocols: Treatment options depend on the severity and functional impact of the webbing. Surgical intervention is often considered to separate fused fingers and improve both function and appearance. The procedure typically involves carefully removing the web tissue, sometimes along with skin grafting to cover the new separation. Post-surgical therapy may include hand therapy to enhance mobility and strength. Early intervention, usually during childhood, can provide better functional and cosmetic outcomes. For less severe cases or when the webbing does not interfere with hand function, observation and regular monitoring may suffice.
