# Bilateral Congenital Hypoplasia of the Extensor Tendons of the Hands

## TL;DR

A rare case of underdeveloped hand tendons in a woman is described, highlighting the challenges in treating this condition.

## Contribution

This case study adds to the limited literature on bilateral congenital extensor tendon hypoplasia and emphasizes the need for better treatment strategies.

## Key findings

- The patient has been unable to extend fingers 2-5 bilaterally since birth.
- Treatment outcomes have been mixed despite surgery and therapy.
- The rarity of the condition complicates diagnosis and treatment.

## Abstract

Congenital hypoplasia or aplasia of the extensor tendons of the hands is an extremely rare condition characterized by an inability to extend the fingers due to underdeveloped or absent extensor tendons. This case study presents a 26-year-old female born with the inability to extend digits 2-5 bilaterally, an anomaly that has significantly impacted her hand function throughout her life. Despite multiple medical evaluations, tendon transfer surgery, and physical and occupational therapy, the patient has experienced mixed outcomes, with marginal improvement in some areas and persistent functional limitations in others. The rarity of this condition poses significant challenges in diagnosis and management, and treatment options must be highly individualized. This case highlights the complexities of managing congenital tendon anomalies and reinforces the need for more research to improve treatment outcomes.
