Q71.21

Clinical Causes: Genetic factors: Abnormalities in chromosomes or inherited gene mutations can contribute to limb formation issues. Environmental influences: Exposure to certain drugs, toxins, or infections during pregnancy may interfere with limb development. Unknown factors: In some cases, the exact cause remains unidentified despite thorough evaluation.

Key Symptoms: Complete or partial absence of the forearm and hand on the right side Possible underdeveloped or malformed remaining limb structures Limited mobility or dexterity in the affected limb Asymmetry in limb appearance Potential associated abnormalities in other parts of the body

Diagnosis Path: Diagnosis often occurs prenatally via ultrasound, which can reveal limb deficiencies early in pregnancy. After birth, physical examinations confirm the absence of the forearm and hand. Imaging techniques such as X-rays provide detailed views of remaining bones and structures, helping to plan for optimal management. Medical history, genetic counseling, and assessment of associated anomalies are also essential components of diagnosis.

Treatment Protocols: While there is no surgical way to replace missing limb parts entirely, various approaches can help improve function and appearance, including: - Prosthetic fitting: Custom-designed prostheses can restore appearance and assist with daily activities. - Occupational therapy: Focuses on improving fine motor skills and adapting to limb differences. - Physical therapy: Aims to enhance overall mobility and strength of remaining limb muscles. - Supportive devices: Adaptive tools and assistive technologies facilitate performance of everyday tasks. - Counseling: Provides emotional support to help individuals adapt psychologically and socially. The choice of interventions depends on individual needs, age, and the extent of the limb deficiency.
