SLAP Tears (Superior Labrum Anterior to Posterior Tears).
What is a SLAP tear?
SLAP tears, or Superior Labrum Anterior to Posterior tears, are injuries to the labrum — the ring of fibrocartilage that surrounds the shoulder joint socket — at the point where the long head of the biceps tendon attaches to the superior labrum. SLAP tears are commonly associated with repetitive overhead activities, shoulder dislocations, or trauma.
The labrum serves two functions: it deepens the relatively shallow glenoid socket — increasing glenohumeral joint stability — and it provides the attachment point for the long head of the biceps tendon at the superior pole. A SLAP tear disrupts one or both of these functions, producing pain, instability and in some cases a mechanical clicking or catching sensation.
SLAP is a descriptive term referring to the location of the tear — from anterior to posterior across the superior labrum — rather than its severity or mechanism. The Snyder classification describes four primary subtypes:
What causes SLAP tears?
Two distinct mechanisms produce SLAP tears. Acute traumatic SLAP tears typically occur from a fall onto an outstretched arm, a shoulder dislocation, or a sudden traction force on the arm — such as catching a heavy falling object or being pulled by the arm. The compressive or traction force drives the humeral head against the superior labrum, producing the tear.
Repetitive overhead SLAP tears develop from cumulative loading of the biceps anchor during throwing, swimming, tennis serving and other overhead activities. The late cocking and deceleration phases of throwing place particularly high stress on the superior labrum — the biceps tendon acts as a brake on the humerus during deceleration, transmitting this force directly to its labral attachment.
What are the symptoms?
Deep shoulder pain — often described as inside the joint rather than on the surface — that is provoked by overhead activities, throwing, lifting with the arm away from the body, or reaching behind the back. A click, pop or catch inside the shoulder with certain movements is characteristic of bucket-handle type tears. Shoulder instability — a feeling that the shoulder is not quite in place or may give way — reflects compromise of the labrum's stabilising function. Biceps-related pain at the front of the shoulder may accompany tears involving the biceps anchor. Night pain, particularly when lying on the affected shoulder, is a common complaint.
How is it diagnosed?
To accurately diagnose SLAP tears, a comprehensive evaluation by a qualified healthcare professional is crucial. The diagnostic process includes medical history review, physical examination assessing range of motion, strength, stability and pain, and special tests including O'Brien's test, Speed's test and the Biceps Load Test which help identify SLAP tears and differentiate them from other shoulder injuries. Imaging studies including MRI or arthroscopy may be recommended to confirm the diagnosis.
MRI arthrography — where contrast is injected into the joint before the MRI — provides significantly better visualisation of the labrum than standard MRI and is the preferred imaging investigation for suspected SLAP tears. However even MRI arthrography has imperfect sensitivity and specificity for SLAP tears, and arthroscopic examination remains the definitive diagnostic standard.
Surgery versus conservative management — what does the evidence say?
This is the most important and most debated question in SLAP tear management, and the evidence has shifted substantially toward conservative management in recent years. Multiple studies have shown that many patients with Type II SLAP tears — the most common type for which surgery was historically recommended — achieve good to excellent outcomes with structured physiotherapy without surgery. A 2012 Norwegian randomised controlled trial found no significant difference in outcomes between surgical repair and supervised physiotherapy for Type II SLAP tears at two years.
Age is one of the most important factors in the surgery versus conservative management decision. Younger overhead athletes with acute traumatic Type II tears and a high demand for overhead performance are more likely to benefit from surgical repair. Older patients, those without the specific demand for throwing or overhead sport, and those with degenerative Type I tears are increasingly managed conservatively with comparable outcomes.

How can physiotherapy help?
Physiotherapy plays a crucial role in the conservative management of SLAP tears. A physiotherapist will design an individualised treatment plan based on the patient's specific needs and goals. The primary objectives include pain management through ice or heat therapy, manual therapy techniques and activity modification, restoring range of motion through exercises to address stiffness and restrictions, strength and stability training targeting the rotator cuff and periscapular muscles to compensate for the labral instability, and neuromuscular retraining to improve shoulder proprioception and dynamic stability.
The physiotherapy approach for SLAP tears focuses on rebuilding the dynamic stability that compensates for the compromised passive stability of the torn labrum. Rotator cuff strengthening — particularly the external rotators and subscapularis — is the primary exercise target. The rotator cuff's role as a dynamic centrer of the humeral head in the glenoid reduces the demand on the labrum as a static stabiliser and is the most important compensatory mechanism to develop.
Scapular stabiliser strengthening — lower trapezius, serratus anterior and middle trapezius — restores the scapular control that positions the glenoid correctly throughout arm movement, reducing the shear and traction forces on the superior labrum.
For throwing athletes, progressive return to throwing following the structured interval throwing program — beginning with short-distance flat ground throwing and progressively building to full throwing demands — is the sport-specific component that determines safe return to overhead sport.
Real time ultrasound assists in retraining deep rotator cuff activation. Clinical Pilates provides a controlled environment for progressive shoulder and scapular strengthening. Dry needling assists with periscapular pain management.
For patients whose SLAP tear occurred in a workplace or motor vehicle context, WorkCover and CTP funded physiotherapy is available.
Our physiotherapists Bethany Kippen and Emma Cameron both have experience in shoulder conditions and are members of the Australian Physiotherapy Association. Mauricio Bara's APA Sports Physiotherapist credentials are particularly relevant for overhead athletes and throwing sport presentations.

SLAP is a descriptive term referring to the location of the tear — from anterior to posterior across the superior labrum — rather than its severity or mechanism. The Snyder classification describes four primary subtypes:
- Type I — degenerative fraying of the superior labrum with an intact biceps anchor. Common in older adults as an age-related finding rather than a traumatic injury, often managed conservatively.
- Type II — detachment of the superior labrum and biceps anchor from the glenoid. The most common clinically significant SLAP tear, producing instability of the biceps anchor and the greatest functional impairment. The primary type for which surgery is considered.
- Type III — bucket-handle tear of the superior labrum with an intact biceps anchor. The torn labral tissue displaces into the joint, producing catching and locking.
- Type IV — bucket-handle tear extending into the biceps tendon itself. The most severe type, often requiring surgical management.
