The ICD-10 code Q71.00 refers to "Congenital complete absence of unspecified upper limb." This classification falls under the broader category of congenital limb deficiencies, which are conditions present at birth that result in the absence or malformation of limbs.

Clinical Description

Definition

Congenital complete absence of an upper limb indicates that an individual is born without one of their upper limbs, which can include the arm, hand, or both. This condition is classified as a reduction defect, where the limb is either partially or completely absent due to developmental issues during gestation.

Etiology

The exact cause of congenital limb deficiencies, including complete absence, can vary. Factors may include genetic mutations, environmental influences, or disruptions during critical periods of limb development in the fetus. Some known teratogenic factors that can contribute to limb deficiencies include maternal drug use, infections during pregnancy, and certain metabolic disorders.

Prevalence

The prevalence of congenital limb deficiencies, including complete absence of limbs, is relatively low. Studies indicate that congenital anomalies of the upper limbs occur in approximately 1 in 1,000 live births, with complete absence being a rarer subset of these anomalies[5].

Clinical Features

• Physical Examination: Infants with this condition will present with the absence of one upper limb. The remaining limb may exhibit normal development, but there may also be associated anomalies in other parts of the body.
• Associated Conditions: Congenital limb deficiencies can sometimes be associated with other congenital anomalies, such as those affecting the heart, spine, or other organ systems. A thorough evaluation is essential to identify any coexisting conditions.

Diagnosis

Diagnosis is typically made through physical examination at birth. Imaging studies, such as X-rays or ultrasounds, may be utilized to assess the extent of the absence and to rule out any associated skeletal anomalies. Genetic counseling may also be recommended to understand potential hereditary factors.

Management and Treatment

Multidisciplinary Approach

Management of congenital complete absence of an upper limb often involves a multidisciplinary team, including pediatricians, orthopedic surgeons, physical therapists, and occupational therapists. The focus is on maximizing the child's functional abilities and quality of life.

Prosthetic Options

For children with the absence of an upper limb, prosthetic devices can be considered. Advances in prosthetic technology have led to the development of functional and aesthetically pleasing options that can assist in daily activities.
