Unable to Externally Rotate Shoulder: Causes, Diagnosis, and Treatment

Nov 27, 2023

Introduction

Welcome to IAOM-US, your trusted source for comprehensive health and medical information. In this article, we will discuss the causes, diagnosis, and treatment options for individuals who are unable to externally rotate their shoulder.

The Importance of Shoulder Mobility

Shoulder mobility plays a crucial role in our daily activities. Whether it's reaching for objects, lifting weights, or participating in sports, a fully functional shoulder joint is essential. The ability to externally rotate the shoulder is particularly important, as it allows us to perform movements such as throwing a ball or reaching behind our backs. However, when individuals experience difficulty or are unable to externally rotate their shoulder, it can significantly impact their quality of life.

Causes of Unable to Externally Rotate Shoulder

There are several potential causes for individuals who are unable to externally rotate their shoulder. These include:

  • Rotator Cuff Injury: A tear in the rotator cuff muscles, tendons, or ligaments can limit shoulder mobility, including external rotation.
  • Shoulder Impingement: This occurs when the space between the acromion (part of the shoulder blade) and the rotator cuff tendons narrows, causing pain and restricted movement.
  • Adhesive Capsulitis (Frozen Shoulder): A condition characterized by stiffness and pain in the shoulder joint, which can limit both passive and active external rotation.
  • Glenohumeral Instability: When the shoulder joint becomes unstable, it can lead to limited range of motion, including external rotation.
  • Shoulder Arthritis: Degenerative conditions like osteoarthritis can affect the shoulder joint, leading to reduced mobility.

Diagnosis

Proper diagnosis is vital in determining the underlying cause of the inability to externally rotate the shoulder. A healthcare professional, such as a chiropractor or physical therapist, will perform a thorough evaluation, including:

  • Medical History: Understanding the patient's medical history and any past injuries or conditions that may contribute to the limited range of motion.
  • Physical Examination: Assessing the shoulder joint, range of motion, and identifying any signs of pain or instability.
  • Diagnostic Imaging: X-rays, MRI scans, or ultrasound may be necessary to evaluate the integrity of the shoulder structures, such as the rotator cuff or joint surfaces.
  • Special Tests: The healthcare professional may perform specific tests to assess the strength, stability, and flexibility of the shoulder joint.

Treatment Options

The appropriate treatment for the inability to externally rotate the shoulder will depend on the underlying cause. Here are some common treatment options:

Conservative Treatments

If the condition is not severe, conservative treatments may be recommended. These can include:

  • Physical Therapy: Targeted exercises and stretches to improve shoulder mobility, strength, and stability. This may include specific exercises to address the external rotation deficit.
  • Chiropractic Care: Gentle manipulations and adjustments to improve joint alignment and function, reducing pain and enhancing mobility.
  • Pain Management: Nonsteroidal anti-inflammatory drugs (NSAIDs) or other pain-relieving medications may be prescribed to alleviate discomfort.
  • Rest and Rehabilitation: Avoiding activities that aggravate the condition while allowing the shoulder to heal and regain strength through rest and proper rehabilitation.

Advanced Treatment Options

In more severe or persistent cases, advanced treatment options may be necessary. These can include:

  • Steroid Injections: Corticosteroid injections can help reduce inflammation and pain in the shoulder joint.
  • Platelet-Rich Plasma (PRP) Therapy: PRP therapy involves using the patient's own blood platelets to promote healing and tissue regeneration in the shoulder joint.
  • Minimally Invasive Surgery: In some cases, arthroscopic surgery may be recommended to repair a torn rotator cuff or address other structural issues contributing to limited external rotation.
  • Rehabilitation Programs: Following surgical intervention, a comprehensive rehabilitation program will be tailored to the individual, focusing on regaining strength, mobility, and function.
