ICD-10: Q69.1

The ICD-10-CM code Q69.1 specifically refers to "Accessory thumb(s)," which is a condition characterized by the presence of one or more additional thumbs. This condition falls under the broader category of polydactyly, which is defined as the presence of extra fingers or toes.

Clinical Description

Definition

Accessory thumbs are extra digits that may be fully formed or rudimentary. They can occur on one or both hands and may vary in size, shape, and functionality. The condition is often congenital, meaning it is present at birth, and can be associated with other congenital anomalies.

Etiology

The exact cause of accessory thumbs is not always clear, but it is believed to result from genetic factors during fetal development. Polydactyly, including accessory thumbs, can be inherited in an autosomal dominant pattern, meaning only one copy of the mutated gene from an affected parent can cause the condition in the offspring. Environmental factors during pregnancy may also play a role, although specific teratogenic influences are less well-defined.

Clinical Presentation

Patients with accessory thumbs may present with:
- Physical Examination: The presence of one or more additional thumbs, which may be located on the radial (thumb) side of the hand. The accessory thumb can be fully functional or may lack bone structure and muscle control.
- Functionality: Depending on the development of the accessory thumb, it may or may not interfere with hand function. In some cases, it can lead to difficulties in grasping or manipulating objects.
- Associated Conditions: Accessory thumbs can occur as part of syndromes that involve other congenital anomalies, such as syndactyly (fusion of fingers) or other limb malformations.

Diagnosis

Diagnosis of accessory thumbs is primarily clinical, based on physical examination. Imaging studies, such as X-rays, may be utilized to assess the bone structure of the accessory digit and to plan for any potential surgical intervention.

Treatment Options

Surgical Intervention

In cases where the accessory thumb is functional or causes significant cosmetic or functional issues, surgical excision may be considered. The decision to proceed with surgery typically depends on:
- The degree of functionality of the accessory thumb.
- The impact on the patient’s quality of life.
- The presence of associated conditions.

Rehabilitation

Post-surgical rehabilitation may be necessary to ensure optimal hand function and to help the patient adapt to any changes in hand structure.
