The subscapularis tendon is a part of the rotator cuff, a bundle of tendons and muscles that support the shoulder joint. It begins in the subscapular fossa of the scapula and ends at the lesser tubercle of the humerus. It is the largest and strongest muscle in the rotator cuff, and its primary function is to enable internal rotation of the arm and adduction. Despite its significance, injuries to this tendon were traditionally referred to as “hidden lesions,” leading to its designation as a “forgotten tendon” in medical literature. This lack of attention in diagnosing and treating shoulder problems could lead to misdiagnosis and inappropriate treatment of related conditions, underscoring the need for a more comprehensive understanding of shoulder health.

Symptoms of subscapularis tendon injuries

 Injuries to the subscapularis tendon can appear as numerous symptoms, including

Anterior Shoulder Pain: A dull discomfort felt at the front of the shoulder that may spread to the armpit.

Pain with Movement: Discomfort that worsens when raising or reaching behind the back.

Weakness: Difficulty twisting the arm inward and lifting objects high.

Stiffness: The shoulder joint has a limited range of motion, which makes daily chores difficult.

Causes of subscapularis tendon injuries

Subscapularis tendon injuries are commonly attributed to:

Overuse: Repetitive shoulder movements are prevalent in sports such as swimming, tennis, and weightlifting and can cause strain.

Trauma: Tears may be caused by acute injuries sustained during falls or accidents.

Degenerative Changes: The tendon’s susceptibility to injury can be exacerbated by age-related wear and strain.

Non-surgical treatment for subscapularis tendon injuries

 Non-surgical interventions concentrate on alleviating pain and reinstating functionality. These comprise:

Rest: Refraining from activities that aggravate symptoms is essential for effective recovery.

Activity Modification: Altering everyday routines to reduce stress on the shoulder may improve discomfort.

Non-steroidal anti-inflammatory medications (NSAIDs): They alleviate pain and inflammation.

Corticosteroid Injections: In certain instances, injections may temporarily alleviate inflammation.

Although some patients have favorable responses to conservative treatment, individuals with substantial rips may necessitate surgical surgery.

 Surgical intervention for subscapularis tendon injuries

 When conservative therapy is ineffective or a full tear is identified, surgical interventions become essential. Surgical procedures generally encompass:

Arthroscopic Repair: This minimally invasive procedure utilizes small incisions to access and mend the ruptured tendon. It facilitates accurate suturing of the tendon to its original position.

Open Repair: In instances of significant damage, an open surgical technique may be utilized to enhance accessibility for repair.

Salvage Protocols: For irreversible tears (designated as Lafosse type V), treatment options consist of tendon transfers or reverse shoulder arthroplasty (RSA), which entails substituting the impaired joint with a prosthetic device.

These surgical methods seek to rehabilitate shoulder functionality and mitigate discomfort efficiently.

Conclusion

The subscapularis tendon is critical for shoulder stability and function, yet it is sometimes disregarded when discussing rotator cuff issues. Understanding the symptoms, root causes, and treatment choices is essential for effective management. Consulting a healthcare specialist is necessary for an accurate diagnosis and treatment plan for a subscapularis tendon injury. It is time for this vital tendon to be given the attention it deserves in orthopedic debates and clinical practice.
