ICD-10: S42.264

The ICD-10 code S42.264 refers to a nondisplaced fracture of the lesser tuberosity of the right humerus. This specific classification falls under the broader category of fractures of the upper end of the humerus, which are common injuries, particularly in the context of shoulder trauma.

Clinical Description

Definition

A nondisplaced fracture indicates that the bone has cracked but has not moved from its original position. In the case of the lesser tuberosity of the humerus, this area serves as an important attachment point for muscles, particularly the subscapularis, which is crucial for shoulder stability and movement.

Anatomy

The lesser tuberosity is a small bony prominence located on the anterior aspect of the humerus, just below the shoulder joint. It plays a significant role in the function of the shoulder, as it provides an attachment for the rotator cuff muscles, which are essential for shoulder mobility and stability.

Mechanism of Injury

Fractures of the lesser tuberosity typically occur due to:
- Trauma: Such as falls, direct blows to the shoulder, or during sports activities.
- Overuse: Repetitive overhead activities can lead to stress fractures, although these are less common.

Symptoms

Patients with a nondisplaced fracture of the lesser tuberosity may experience:
- Pain: Localized pain in the shoulder, particularly with movement.
- Swelling: Swelling around the shoulder joint.
- Limited Range of Motion: Difficulty in moving the arm, especially in internal rotation.
- Tenderness: Tenderness upon palpation of the lesser tuberosity.

Diagnosis

Imaging

Diagnosis is typically confirmed through imaging studies, including:
- X-rays: Standard X-rays can reveal the fracture and assess its displacement.
- MRI or CT scans: These may be used for a more detailed view, especially if there is concern about associated injuries to the rotator cuff or other structures.

Clinical Examination

A thorough clinical examination is essential, focusing on:
- Range of Motion: Assessing both active and passive movements.
- Strength Testing: Evaluating the strength of the shoulder muscles, particularly those attached to the lesser tuberosity.

Treatment

Conservative Management

Most nondisplaced fractures can be managed conservatively, including:
- Rest: Avoiding activities that exacerbate pain.
- Immobilization: Using a sling to support the arm and limit movement.
- Physical Therapy: Once healing begins, rehabilitation exercises to restore range of motion and strength are crucial.

Surgical Intervention

In rare cases where conservative treatment fails or if there are complications, surgical options may be considered, such as:
- Open Reduction and Internal Fixation (ORIF): This procedure involves realigning the fracture and securing it with hardware.

Prognosis

The prognosis for nondisplaced fractures of the lesser tuberosity is generally favorable, with most patients experiencing a full recovery with appropriate treatment. Rehabilitation plays a critical role in restoring function and preventing future injuries.

In summary, the ICD-10 code S42.264 encapsulates a specific type of shoulder injury that, while potentially painful and limiting, often responds well to conservative treatment strategies. Understanding the clinical implications and management options is essential for effective patient care.
