SLAP REPAIR

SLAP is an acronym for Superior Labrum Anterior to Posterior. It describes a labral detachment that originated posterior to the long head of the biceps tendon and extends anteriorly. The superior and inferior labrums differ in numerous ways. Whereas the inferior labrum is firmly attached to the glenoid and is more inelastic, fibrous tissue, the superior labrum resembles the meniscus in the knee – it is loosely attached to the glenoid, is triangular in shape, and has a fibrocartilaginous consistency. The long head of the biceps tendon has an attachment on both the posterosuperior labrum and the supraglenoid tubercle.

There are four types of SLAP lesions. Type I occurs when there is degeneration and fraying of the labrum but it remains firmly attached to the glenoid. There is no avulsion of the biceps tendon. A Type II lesion also shows signs of degenerative changes and fraying and there is complete detachment of the labrum from the superior glenoid rim. The attachment of the biceps is unstable. In a type III SLAP lesion, there is a bucket-handle tear of the labrum and the free margin is displaced into the joint. The labrum and biceps attachments are stable however. In this type of lesion, mechanical symptoms similar to those found in bucket-handle meniscal tears of the knee can be present, including catching and locking. A type IV SLAP lesion occurs when the superior portion of the labrum is displaced into the joint and the long head of the biceps is partially ruptured.

The two most common mechanisms of injury causing SLAP lesions are compression forces such as would occur when attempting to catch a heavy, falling object and traction forces, experienced during activities such as water skiing and throwing. It is not unusual and often expected to have associated inferior instability and/or a rotator cuff tear with a SLAP lesion.

SLAP lesions are difficulty to diagnose through physical exam and MRIs and are often only found upon arthroscopic examination.

It is of utmost importance to know the type of SLAP lesion sustained because the surgical procedure and subsequent rehab protocol differ for each type. Type I and III SLAP lesions are treated by debridement and because the biceps tendon is stable, post-op rehab can progress as tolerated. There are no restrictions of ROM.

The following protocol is for patients who have sustained a Type II or IV SLAP lesion in which the biceps tendon is unstable and possibly ruptured. The biceps tendon and labrum must be stabilized using tacks or suture anchors and if a Type IV lesion has occurred, the biceps must be repaired. Because of this, it is important to avoid stress on the repaired area post-operatively. ROM limitations should be followed closely and active biceps work must be limited for the first 6 weeks. Active biceps work is restricted because it has been shown that, if a SLAP lesion is present, contraction of the biceps actually lifts the superior labrum off the glenoid. The therapist must also remember that other procedures to correct instability or a RCT may have been performed concomitantly with the SLAP repair. If this is the case, the most conservative of the post-op protocols for all procedures performed is usually the one that is followed.

Rehab must be specific to the individual. The desired goals and work requirements must be taken into consideration as well as physical characteristics including age and tissue type and status.

Suggestions during rehab:

  1. The RC gets a better blood supply when the shoulder is slightly away from the body; therefore, advocate the use of a towel roll under the arm when in a resting position.
  2. The RC muscles are very small; therefore, we use lower intensities to isolate each muscle without recruitment from surrounding larger muscles. Focus on hypertrophy initially by high volume (V= Reps X intensity/weight). Following the hypertrophy phase, strength is the focus with lower reps and higher intensities/weight.

New August 2011:

DS2 Platform: Patient places gloved hand on board, applies pressure, then moves hand from dot to dot in pre-determined patterns.

We have begun using a new rehab tool called the DS2 Platform. Th is a wall mounted low-friction board that is a versatile tool for closed chain rotator cuff and scapular exercises. It can be used for patient-controlled closed chain stretching as well as for strengthening of the cuff. In the early strengthening phase, active assisted exercises are initiated and progressed to high repetition exercises in various patterns. The resistance is adjusted by modifying how much pressure the patient places on the board. The board mounts on the wall, uses no floor space, and is very versatile. The DS2 Platform was invented by Roland Ramirez ATC LAT MPT SCS CSCS. Roland is the Coordinator of Rehabilitation for the Houston Texans football team.

PROTOCOL

PHASE ONE

(Week 1-3)
In phase one, the general goals are to protect the surgical repair, initiate ROM to prevent adhesions and increase circulation, decrease pain and inflammation, and stress emphasis of HEP.

A sling will be worn for 4 to 6 weeks unless instructed otherwise by Dr. Lintner.

The sling is to be removed 2-3X/day to perform HEP.

ROM limitations:

Passive and active-assisted ROM ONLY:

Flexion/scaption 0-60° by week 1

0-75° by week 2

0-90° by week 3

ER in scapular plane 0-15° by week 1

0-30° by week 2-3

IR in scapular plane as tolerated

Active wrist and elbow full ROM

EXERCISES:

ROM:

  • Pendulums
  • Rope and pulley – flexion, scaption
  • AA cane/wand into flexion, ER at 0° and 45°
  • Seated table slides on DS2 Platform
  • Seated or supine posterior cuff stretch into horiz adduction
  • Grade I-II g-h and scapular joint mobs and manual stretching

STRENGTH:

  • Hand gripping exercises – putty
  • Submax pain-free isometrics at 0° abduction (IR, ER, Ext, Abd) – NO ELBOW or SHOULDER FLEXION

  • Ice following tx and when needed

PHASE TWO

(Week 3-6)
General goals in Phase Two are to gradually restore ROM, initiate active muscle contractions with a focus on regaining proper scapulo-humeral rhythm, begin to train joint proprioception, and continue with HEP.
