What Do You Need to Know About Rotator Cuff Injury?

What is a Rotator Cuff Injury?

A rotator cuff is a group of muscles and tendons that surround the shoulder joint, keeping the head of your upper arm bone firmly within the shallow socket of the shoulder. A rotator cuff generally produces severe pain in the affected shoulder, especially at night, often preventing sleep.

Rotator cuff injuries or rotator cuff tears often occur in people who repeatedly perform overhead motions in their jobs or sports. Examples include painters, carpenters, and people who play baseball or tennis. The risk of rotator cuff injury also increases with age and with certain diseases like diabetes & thyroid disorders.

Types of Rotator Cuff Injury 

There are two main types of torn rotator cuffs, each with its own characteristics and implications.

Partial Tear

A partial tear of the rotator cuff occurs when the tendon connecting the shoulder muscles to the arm bone is partially damaged but still maintains some attachment. In such cases, the tendon is not completely separated from the bone.

Complete Tear

A complete tear of the rotator cuff, also known as a full-thickness tear, occurs when the tendon completely detaches from the bone. This results in a hole or rip in the tendon, causing a more severe and debilitating injury.

Rotator Cuff Tear Symptoms 

Rotator cuff tears can manifest with various symptoms. Understanding these signs is crucial for timely diagnosis and treatment. Here are some common symptoms associated with rotator cuff tears:

• Pain and Weakness: A person may experience pain and weakness when raising, lowering, or rotating their arm.
• Audible or Sensational Signs: Some people notice popping, clicking, or crackling sounds or sensations when moving their arm in certain positions.
• Nighttime Discomfort: Shoulder pain often worsens at night.
• Shoulder Weakness: A person might find it challenging to lift items or perform daily activities due to shoulder weakness.

Causes of Rotator Cuff Injury

Dr. Raju Easwaran, Senior Consultant, Max Super Speciality Hospital, Shalimar Bagh, mentions a few causes of rotator cuff injuries:

Falling

Using your arm to break a fall or falling on your arm can bruise or tear a rotator cuff tendon or muscle.

Lifting or Pulling

Lifting an object that's too heavy or doing so improperly — especially overhead — can strain or tear your tendons or muscles. This applies especially to people doing shoulder pressure in the gym using hefty weights or improper techniques.

Repetitive Stress

Engaging in repetitive overhead movements, such as those common in racquet sports, can significantly strain the muscles and tendons of one's rotator cuff. This continual stress may lead to inflammation and, over time, result in tearing. In this article, we will explore the impact of repetitive overhead motions on the rotator cuff and discuss preventative measures to maintain shoulder health in racquet sports.

Bone Spurs

An overgrowth of bone can occur on a part of the shoulder blade that protrudes over the rotator cuff. This extra bone can irritate and damage the tendon. This generally happens with ageing.

What are the Risk Factors for Rotator Cuff Injuries?

The following factors may increase your risk of rotator cuff injury:

• Age: As you age, the risk of experiencing rotator cuff injury increases. Rotator cuff tears are most common in people older than 40.
• Certain sports: Athletes who regularly use repetitive arm motions, such as baseball pitchers, archers, and tennis players, have a greater risk of rotator cuff injury.
• Construction jobs: Occupations such as carpentry or house painting require repetitive arm motions, often overhead, that can damage the rotator cuff over time.

What Does a Rotator Cuff Injury Feel Like? 

Shoulder pain is a common issue that can manifest in various ways, ranging from a persistent dull ache to a sudden, sharp, stabbing sensation. This discomfort can result from accidents or trauma, leading to immediate discomfort and weakness in the arm. In other cases, individuals may initially experience mild pain due to degenerative tears, which can often be managed with over-the-counter pain relievers. 

What are the Complications of a Rotator Cuff Injury? 

Neglecting a rotator cuff tear can lead to a worsening of the condition. When the tear is severe, it can severely limit the arm's mobility. Untreated rotator cuff injuries may result in persistent shoulder pain and substantial impairment when it comes to using the affected arm.

How is a Rotator Cuff Injury Diagnosed?

Rotator cuff injury diagnosis involves several essential components, including physical tests and imaging studies.

Physical Examination

During a physical examination, orthopaedic surgeons perform a series of assessments to evaluate the affected shoulder comprehensively. They press on various shoulder parts, manipulate the arm into different positions, and assess the strength of the muscles surrounding the shoulder and the arms. This hands-on examination helps them identify specific issues and understand the overall condition of the shoulder.

Imaging Tests

Besides the physical exam, imaging tests are crucial in diagnosing shoulder injuries. These tests provide detailed insights into the internal structures of the shoulder, helping healthcare providers make an accurate diagnosis. The following imaging techniques are commonly employed:

• X-rays: While X-rays cannot directly visualise rotator cuff tears, they are valuable for identifying other potential causes of shoulder pain, such as bone spurs or arthritis. 
• Ultrasound: Ultrasound employs sound waves to generate images of soft tissues, including muscles and tendons. 
• Magnetic Resonance Imaging (MRI): MRI technology utilise radio waves and powerful magnets to create highly detailed images of the shoulder's internal structures. 

By integrating these diagnostic tools, orthopaedic doctors in Delhi and other locations can develop a precise understanding of your shoulder condition, allowing them to recommend the most suitable treatment options

Treatment of Rotator Cuff Injury

Rotator cuff tear treatment is critical for individuals dealing with this injury. The appropriate treatment depends on the extent of the tear and associated symptoms. 

Conservative

For milder cases of rotator cuff tears, conservative rotator cuff tear treatment is often sufficient:

• Rest: Adequate rest is crucial to allow the injured tissue to heal. It's an essential aspect of rotator cuff tear treatment.
• Ice: Applying ice to the affected area can help reduce pain and inflammation during rotator cuff tear treatment.
• Physical Therapy: Physical therapy is pivotal in rotator cuff tear treatment. Tailored exercises can improve shoulder flexibility and strength. Moreover, physical therapy is vital for post-surgery rehabilitation.

Injections

In some cases, mainly when pain significantly affects daily life or hinders physical therapy progress, a steroid injection into the shoulder joint may be recommended as part of rotator cuff tear treatment. It's important to note that while these injections can provide temporary relief, they may weaken the tendon and affect the success of future surgical procedures.

Surgical Options

Rotator cuff surgery may be necessary for more severe rotator cuff tears. Various rotator cuff surgical procedures are available:

• Arthroscopic Tendon Repair: This minimally invasive procedure, as part of rotator cuff tear treatment, involves the use of a tiny camera (arthroscope) and specialised tools to reattach the torn tendon to the bone through small incisions.
• Open Tendon Repair: In certain situations, an open tendon repair may be the preferred choice for rotator cuff tear treatment. This procedure requires a larger incision but allows surgeons to reattach the damaged tendon to the bone effectively.
• Tendon Transfer: When the torn tendon is too damaged for direct reattachment, surgeons may use a nearby tendon as a replacement, a critical aspect of rotator cuff tear treatment.
• Shoulder Replacement: In cases of massive rotator cuff tears, shoulder replacement surgery may be necessary as a form of shoulder cuff tear treatment. An innovative technique known as reverse shoulder arthroplasty involves attaching the ball part of the artificial joint to the shoulder blade and the socket part to the arm bone, enhancing joint stability.

Recovery after a Rotator Cuff Injury

Recovery from a rotator cuff injury varies depending on its severity and treatment. Mild cases often heal within a few weeks to several months with proper care, while severe injuries may require several months of rehabilitation or, in some cases, surgical intervention. It's crucial to strike a balance between rest and movement during recovery, as excessive immobilisation can lead to a condition known as a frozen shoulder.

Preventing Rotator Cuff Injuries

If you are at risk of rotator cuff injuries or if you've had a rotator cuff injury in the past, daily shoulder stretches and exercises can help prevent future injury. 

Most people exercise the front muscles of the chest, shoulder and upper arm, but it is equally important to strengthen the muscles in the back of the shoulder and around the shoulder blade to optimise shoulder muscle balance. Your orthopaedic surgeon or a physical therapist can help you plan an exercise routine. In extreme cases, you may require an arthroscopic cuff repair.
