ICD-10: Q65.81

Congenital coxa valga is a specific condition classified under the ICD-10 code Q65.81. This condition is characterized by an abnormal angle between the femoral neck and the femoral shaft, leading to an outward angulation of the hip joint. Below is a detailed overview of the clinical description, implications, and management of congenital coxa valga.

Clinical Description

Definition

Coxa valga refers to a deformity of the hip joint where the angle between the femoral neck and the femoral shaft exceeds 135 degrees. In congenital cases, this condition is present at birth and can result from various developmental issues during fetal growth.

Etiology

The exact cause of congenital coxa valga can vary, but it is often associated with:
- Genetic factors that affect bone development.
- Neuromuscular disorders that influence muscle tone and joint stability.
- Conditions such as cerebral palsy or developmental dysplasia of the hip (DDH) that may predispose individuals to this deformity.

Symptoms

Patients with congenital coxa valga may present with:
- Hip pain or discomfort, particularly during movement.
- Limited range of motion in the hip joint.
- A noticeable limp or altered gait pattern.
- In severe cases, it may lead to osteoarthritis or other degenerative changes in the hip joint over time.

Diagnosis

Clinical Evaluation

Diagnosis typically involves a thorough clinical examination, including:
- Assessment of hip range of motion.
- Evaluation of gait and posture.
- Observation for any associated musculoskeletal abnormalities.

Imaging Studies

Radiological imaging is crucial for confirming the diagnosis and may include:
