ICD-10: S42.262

The ICD-10 code S42.262 refers to a displaced fracture of the lesser tuberosity of the left humerus. This specific code is part of the broader classification of shoulder and upper arm injuries, particularly focusing on fractures of the humerus, which is the long bone in the upper arm.

Clinical Description

Anatomy and Function

The lesser tuberosity is a small bony prominence located on the anterior aspect of the humerus, serving as an attachment point for the subscapularis muscle, which is crucial for shoulder movement and stability. Fractures in this area can significantly impact shoulder function due to the muscle's role in internal rotation and stabilization of the shoulder joint.

Mechanism of Injury

Displaced fractures of the lesser tuberosity typically occur due to:
- Trauma: Such as falls, direct blows to the shoulder, or high-energy injuries like those sustained in sports or vehicular accidents.
- Overuse: In some cases, repetitive overhead activities may contribute to stress fractures, although these are less common.

Symptoms

Patients with a displaced fracture of the lesser tuberosity may present with:
- Pain: Localized pain in the shoulder, particularly with movement.
- Swelling and Bruising: Around the shoulder joint.
- Limited Range of Motion: Difficulty in moving the arm, especially in internal rotation.
- Deformity: In some cases, there may be visible deformity or abnormal positioning of the shoulder.

Diagnosis

Diagnosis typically involves:
- Physical Examination: Assessing pain, swelling, and range of motion.
- Imaging Studies: X-rays are the primary imaging modality used to confirm the fracture and assess its displacement. In some cases, MRI or CT scans may be utilized for a more detailed evaluation of the fracture and surrounding soft tissues.

Treatment Options

Non-Surgical Management

In cases where the fracture is non-displaced or minimally displaced, conservative treatment may include:
- Rest and Immobilization: Using a sling to support the arm.
- Pain Management: Non-steroidal anti-inflammatory drugs (NSAIDs) to alleviate pain and swelling.
- Physical Therapy: Gradual rehabilitation to restore range of motion and strength once healing begins.

Surgical Intervention

For displaced fractures, surgical options may be necessary, including:
- Open Reduction and Internal Fixation (ORIF): This procedure involves realigning the fractured bone fragments and securing them with plates and screws.
- Shoulder Arthroscopy: Minimally invasive techniques may be employed to repair the fracture and any associated soft tissue injuries.
