SLAP tears are a common problem for overhead athletes among others today. There is no consensus per se in how to treat them and results following primary repair are mixed. Common complaints following a repair are persistent pain and stiffness. In the past, I have writtne about SLAP tears as well as outcomes for elite pitchers.
In addition, I have discussed outcomes for type 2 SLAP tear revision surgery on this blog. What always concerns me (and more importantly patients who undergo surgery is how to achieve predictable pain relief and recover shoulder function. In the April 2014 edition of the American Journal of Sports Medicine, there is a level 4 prospective study by McCormick et al. looking at the efficacy of subpectoral biceps tenodesis as a viable solution for failed primary SLAP repairs. The study took place from 2006-2010 and all procedures were performed by 2 fellowship trained surgeons at a tertiary military facility.
Subjects: Active-duty men and women b/w 18 and 50 years old who had arthroscopically confirmed type 2 SLAP lesions and who then underwent arthroscopic repair and were subsequently unable to return to duty(follow-up period was 2-6 yeaers with mean follow-up of 3.5 years). They also had to consent to a biceps tenodesis to address the failed repair. All told, 42 of 46 patients completed the study. The mean age was 39.2, while 85% of the subjects were male.
Criteria to be included in the study: inability to return to active duty within a minimum 6 months of surgery, ASES score less than 75 at 1 year follow-up from the primary procedure, or patient electing to undergo revision surgery due to dissatisfaction with the primary results.
Procedure: Biceps tendon was released and the remaining stump was debrided so the superior labrum was confluent with the remaining labral tissue. All sutures and loose anchors were removed. If the rotator cuff interval was inflamed, debridement with a 4.o mm shaver was used and/or radiofrequency wand was used. Next, a 2 cm incision was made in the axillary skin crease at the inferior border of the pec major. The biceps tendon was anchored 1 cm proximal to the musculotendinous junction using a nonabsorbable suture and 8 x 12 interference anchor fixation.
Rehab protocol: Patients were in a sling for 4 weeks with no active biceps use for 6 weeks. They all underwent graded supervised physical therapy consisting of an initial 6-week phase of passive ROM exercise in addition to scapular and core strengthening. This was followed by progressive strengthening at 6 weeks and return to-duty-evaluation at 3 months post-op.
Results
Summary
Currently, there is no standard of care for failed SLAP repairs. One previous case control study by Boileau et al. found higher satisfaction in those undergoing biceps tenodesis compared to arthroscopic repair in the management of an isolated SLAP tear. Further, in the Boileau study there were no failed tenodesis procedures and those opting for that as revision had a full return to previous sports activity. This prospective study by McCormick et al. resulted in similarly high rates of return to previous activity and clinically significant improvements in outcome scores and ROM.
There are several reasons why primary SLAP repairs may fail including: postoperative stiffness as a result inadvertent restriction of physiological biceps excursion or nonanatomic biceps anchor reduction, suture anchor pullout, suture granuloma formation, suture pullout, synovitis, glenoid osteochondrolysis from prominent hardware, a suprascapular nerve injury (due to prominent mendial hardware placement), and a delaminated long head of the biceps.
It is also important to keep in mind the anterior-superior labrum and glenoid are poorly vascularized, and this is thought to limit the healing process. Persistent pain may manifest after surgery in light of the fact the proximal intra-articular portion of the long head of biceps tendon contains sensory and sympathetic fibers associated with shoulder pain. The authors’ findings at the revision procedure in this study suggest a consistent constellation of multifactorial complicating factors including: synovitis of the rotator cuff interval, loose knots, and a lack of healing at the glenoid interface.

Shoulder surgery is a big concern for any professional pitcher. I am currently rehabbing two MLB pitchers (one from a labral repair and the other from a Tommy John procedure and obviously not JV pictured above). They are doing great so far in their early rehab, but time will tell if they make it back to their pre-injury pitching levels.
Overuse injuries in youth baseball players is always a huge concern I have. In fact, I speculate that early wear and tear may contribute to injuries seen down the road in HS, college or the pro ranks. I know from coaching and observing that more youth coaches need to familiarize themselves with pitch count guidelines and rest/recovery recommendations that Little League baseball now endorses.
As a sports physical therapist who sees 12 year-olds with RC problems and torn UCLs and as a father/coach of a 10 y/o left-handed pitcher, I have a strong passion and vested interest in the welfare of baseball pitchers. While research does not equate increased injury risk with throwing curveballs and sliders to date per se, both of my MLB clients advise against it until athletes turn 14 or 15.

Today’s blog post focuses on outcomes following surgery for elite pitchers. The following information was just published in the Jul/Aug 2013 edition of Sports Health by Harris et al. based on literature review based on these outcome measures:
Primary = pitcher’s rate of return to sport (RTS) at the same level prior to injury
Secondary = rates of RTS regardless of level, performance upon RTS and clinical outcome scores
“Elite” was defined as throwing in at least one game in MLB, minor league (A, AA, or AAA) or all collegiate divisions. Six level I-IV studies were included with enrollment from 1976 – 2007, and there were 287 elite male pitchers who underwent shoulder surgery with 99% on the dominant throwing shoulder. Most pitchers (276) were professional with a mean career length of 6.58 years. Post-operative clinical follow-up within these studies was 3.62 years.
Primary diagnoses treated:
Surgical procedures performed:
The statistics reveal more debridement of the labrum (61%) and rotator cuff (85%) versus repair. This is not necessarily surprising given the desire to minimize surgical intervention and loss of motion.
Return to Sport Data
Performance declined for the 3 seasons prior to surgery and then gradually increased for 3 seasons afterward, but generally did not reach pre-injury levels.
So, I treat a number of fitness enthusiasts in the clinic and many include Crossfit clients. Recently, I evaluated a 38 y/o male on 2/16/12 with a 3 month history of right shoulder pain. He performs Crossfit workouts 6 days per week. His initial intake revealed:
Notice the shoulder position during the kipping pull-up and overhead squat below. This is a position of heightened risk for the shoulder.
His exam revealed the following:
Based on the clinical exam, it was apparent he had rotator cuff inflammation and perhaps even a tear. Keep in mind he had not seen a physician yet. I began treatment focused on scapular stabilization and rotator cuff strengthening as well as pec and posterior capsule stretching to address the impingement. Ultrasound and cryotherapy were used initially to reduce pain and inflammation.
One month following the eval
By 3/14/12, his pain was resolved with daily activity and he had returned to snatches and push-press exercises without pain. He still could not do overhead squats with the Olympic bar pain free, but he could with a pvc pipe. Strength was now 4/5 for supraspinatus and 4+/5 for external rotation. All impingement tests were now negative as were Speed’s and O’Brien’s testing.
I have been attending the 26th Annual Cincinnati Sports Medicine Advances on the Shoulder and Knee conference in Hilton Head, SC. This is my first time here and the course has not disappointed. I have always known that Dr. Frank Noyes is a very skilled surgeon and has a great group in Cincinnati as I am originally an Ohio guy too.
So, I thought I would just share a few little nuggets that I have taken away from the first three days of the course so far. I am not going into great depth, but suffice it to say these pearls shed some light on some controversial and difficult problems we see in sports medicine.
Shoulder Tidbits
Knee Tidbits
These are just some of the highlights I wanted to pass along. There was lots of other good stuff (much of it a nice review of anatomy, biomechanics and protocol guidelines for rehab) but I wanted to pass along some of these key items while they were fresh in my head. I will likely be sharing more in the future, particularly with respect to patello-femoral pain and SLAP tears as these are just so controversial in terms of surgical and rehab management.
In most gyms and training circles, people are performing bench press or push-up exercises. There is no doubt in my mind that repetitive heavy full range bench press causes many of the labral and cuff injuries among males I have seen over the years These injuries are often the attritional type – developing over many months and years.
What about push-ups? Is the force development pattern the same? Are they safer? Honestly, I believe in keeping the elbow at a point at which it does not drop below the plane of the body (bench press) or move above the body (push-up). Essentially that means keeping to a 90 degree angle or less. Why? Well, regardless of load, I feel the real risk is not so much in the motion itself but the very repetitive manner in which it occurs with external loads, often lending itself to acquired anterior shoulder laxity, strain on the proximal biceps anchor (think SLAP lesions) and secondary shoulder impingement. The picture below hurts my shoulders just looking at it, and over time this technique will hurt your shoulders too.
But, I say all that to set up today’s post. In a recent article in the February edition of the Journal of Strength & Conditioning Research, David Suprak et al. looked at the effect of position on the % of body mass supported during traditional and modified push-ups.
The study looked at 4 static positions in 28 males (about 34 years old) who were highly trained and members of the special forces or SWAT team (the up and down position for regular and modified push-ups) to determine the change in body mass (BM) supported by the upper body in different ranges of motion. The down positions studied were at approximately 90 degrees (the lowest depth I safely recommend) and all holds were performed for 6 seconds.
