ICD-10: S73.015

The ICD-10 code S73.015 specifically refers to a posterior dislocation of the left hip. This condition is characterized by the displacement of the femoral head from its normal position in the acetabulum, primarily occurring in a posterior direction. Below is a detailed clinical description and relevant information regarding this diagnosis.

Clinical Description

Definition

A posterior dislocation of the hip occurs when the femoral head is forced out of the acetabulum, typically due to trauma or injury. This type of dislocation is the most common form of hip dislocation, often resulting from high-energy impacts, such as motor vehicle accidents or falls from significant heights.

Mechanism of Injury

The mechanism of injury for a posterior hip dislocation usually involves:
- Flexion and Adduction: The hip is often flexed and adducted at the time of injury, which can occur during activities such as sports or accidents.
- Trauma: Direct trauma to the hip area, particularly from a fall or collision, can lead to this type of dislocation.

Symptoms

Patients with a posterior dislocation of the left hip may present with:
- Severe Pain: Intense pain in the hip region, often radiating to the thigh.
- Inability to Move the Leg: The affected leg may appear shortened and internally rotated, making movement difficult.
- Swelling and Bruising: Localized swelling and bruising around the hip joint may be observed.

Diagnosis

Diagnosis typically involves:
- Physical Examination: Assessment of the hip's range of motion and alignment.
- Imaging Studies: X-rays are commonly used to confirm the dislocation and rule out associated fractures. In some cases, CT scans may be utilized for a more detailed view.

Treatment

The management of a posterior dislocation of the left hip generally includes:
- Reduction: The primary treatment is the closed reduction of the dislocated hip, which is often performed under sedation or anesthesia.
- Post-Reduction Care: Following reduction, the hip may be immobilized in a specific position to allow for healing.
- Rehabilitation: Physical therapy is crucial for restoring function and strength to the hip joint after the dislocation has been addressed.

Complications

Potential complications associated with posterior hip dislocations include:
- Avascular Necrosis: Disruption of blood supply to the femoral head can lead to necrosis.
- Recurrent Dislocation: Some patients may experience recurrent dislocations, necessitating further intervention.
