Injuries & conditions SLAP

SLAP lesion

Superior labral anterior-to-posterior lesion (SLAP)

Back to dictionary

In plain language

Injury of the superior shoulder labrum around the long-head biceps attachment; patterns range from fraying to unstable detachment.

01

Clinical Significance & Management

Interpret trauma, throwing load, age and associated cuff disease together. Load modification, mobility and scapular-cuff rehabilitation generally precede surgery. Persistent disability may prompt discussion of debridement, repair or biceps tenodesis.

02

Symptoms & Clinical Presentation

1

Deep pain with overhead activity and reduced performance

2

Clicking or catching, which are not specific

03

Etiology & Injury Mechanisms

  • A fall or sudden arm traction
  • Repetitive throwing and age-related degeneration
04

Diagnostics & Imaging Guide

Examine motion, cuff strength and scapular control; no single maneuver establishes diagnosis

Selected MRI or MR arthrography interpreted clinically

05

Treatment Options

Option 1

Modify provoking loads and progressively strengthen; appropriate analgesia

Option 2

Select surgery after unsuccessful rehabilitation according to tissue, stability and goals

06

Rehabilitation Milestones & Timeline

Rehabilitation depends on the diagnosis, procedure and associated injuries. Progression requires assessment of healing, symptoms and function; elapsed time or a single test cannot determine readiness for sport.

Protection

Control symptoms; protect the labrum and biceps attachment after repair

Recovery

Restore motion and endurance; resisted elbow flexion follows the procedure-specific plan

Sport

Progress throwing after strength, control and load tolerance assessment

Red Flags & Urgent Warnings

Seek immediate emergency or specialist orthopaedic evaluation if any of the following occur:

Traumatic deformity, coldness or persistent numbness needs urgent care

New marked weakness or restricted motion warrants review

07

Evidence-Based Clarifications

An MRI tear need not cause the pain. A trial in selected isolated type II lesions does not justify routine surgery or settle every athlete's case.
