Biceps Management and Subacromial Bursectomy

1

Perform biceps tenotomy vs tenodesis

  • Tenotomy: cut biceps tendon at anchor with sissors
  • Tenodesis:
  • pierce biceps tendon with spinal needle coming into the joint from the anterior lateral acromial border, though the rotator cuff interval, and through the biceps tendon
  • after pierced and held, cut tendon at anchor with scissors.
  • leave spinal needle to hold tendon

2

Perform subacromial bursectomy

  • Move trocar into subacromial space
  • move the arthroscope to the subacromial space
  • slide the trocar under the acromiom over the posterior rotator cuff
  • sweep under the acromiom through the lateral gutter to break up adhesions
  • Identify the CC ligament
  • found on the anterior aspect of the subacromial space
  • Perform a Bursectomy
  • use the shaver to perform a lateral and anterior bursectomy through anterior portal

3

Perform biceps tenodesis

  • Move camera to Posterior lateral portal
  • use Spinal needle to make a posterior lateral portal just off the acromion.
  • this allows for visualization down into the bicipital groove in the humerus.
  • Make stab incision
  • use switching sticks to place camera into posterior lateral portal, place canula into the original posterior portal.
  • Localize biceps tendon in groove
  • use Pre-operative biceps marking as guide
  • Place passport canula centered over tendon in grove
  • Release the roof of the bicipital grove
  • use RF to feel the tendon and start by releasing lateral
  • careful to not cut tendon itself
  • Size the tendon
  • use tendon sizer
  • most common size is 7mm & 8mm
  • Isolate tendon medially
  • use tendon sizer to push tendon medial and place a spinal needle into it to hold position
  • Drill Potting hole
  • use a piloted reamer that is 5mm larger than the selected implant
  • Remove spinal needle holding tendon medially
  • tendon will return to position and be above the hole
  • Implant biceps specific forked screw and tendon
  • push forked screw implant into passport and down onto tendon above the hole
  • place tension with forked implant
  • implant until screw is flush with cortex
  • will have tension via proximal spinal needle holding it
  • remove the proximal spinal needle
  • screw down implant and fix tendon
J

Rotator Cuff Evaluation, Acromioplasty and Distal Clavicle Resection

1

Evaluate rotator cuff tear

  • Insert an atraumatic grasper through the lateral subacromial portal and asses rotator cuff tear lateral excursion.
  • If there is possibility of repair, attempt. If not, proceed with superior capsular reconstruction.
  • If there is a subscapularis tear it must be repaired to ensure humeral head stabilization with the SCR.

2

Perform acromioplasty

  • partially resect the cc ligament with the ablation wand to expose the entire acromium
  • start the acromioplasty at the anterior lateral corner and remove 5 to 8 mm of bone with burr
  • carry the resection medially to the AC joint
  • make the resection level by sweeping the burr from anterior to posterior

3

Distal Clavicle Excision (if performed)

  • Expose distal clavice
  • use RF from lateral portal to clean out and expose the distal clavicle
  • place RF in anterior portal so its parallel with AC joint and continue to expose
  • Resect with burr through anterior portal
  • use 5.0mm burr to resect distal clavicle from anterior to posterior
  • resect only 8m-1CM of distal clavicle
  • if more is done will release the CC ligaments and cause instability
  • be careful to not release the superior capsular of AC joint
K

Superior Capsular Reconstruction (SCR) and Graft Preparation

1

Begin superior capsular reconstruction

  • Prepare greater tuberosity
  • use shaver or burr to decorticate greater tuberosity

2

Prepare Glenoid

  • use RF and shaver to remove superior labrum expose superior glenoid
  • use shaver or burr to decorticate superior glenoid

3

Place Lateral Portal Passport

  • place 12mm passport
  • cut 25% of the inner ring off so that future anchor placement is easier
  • spin the cut section superiorly

4

Place glenoid anchors

  • Create a superior portal (Neviaser)
  • portal medial to acromial, posterior to clavicle, anterior to supraspinatus spine
  • use spinal needle to find trajectory that allows for glenoid anchor placement
  • Glenoid anchor placement
  • place drill guild through superior portal.
  • drill and keep guild in place for anchor placement.
  • place 2-3 knotless 2.9mm suture tack anchors. (depending on size of glenoid) anterior to posterior.
  • place hemostat on limbs from each anchor
  • occasionally may need to make another portal just posterior to the first to get trajectory for 3 anchors.

5

Place greater tuberosity anchors

  • use spinal needle just lateral off lateral border of acromion.
  • small stab incision to allow for punch and anchor passage.
  • Place Anchors
  • place first 4.75mm fibertape loaded anchor on the anterior greater tuberosity
  • use suture grasper to take suture out anterior canula
  • place second 4.75mm fibertape loaded anchor on the posterior tuberosity
  • use grasper to take suture out of posterior cannula.

6

Measure Graft

  • Measure Anterior and Lateral
  • bring the suture from the anterior humeral anchor out the speed bridge and apply the intra-articular suture measurement device
  • meausre the distance between the 2 humeral anchors and write down the number. (Lateral)
  • measure the distance between the anterior humeral anchor and the most anterior glenoid anchor and write down the number (Anterior)
  • Measure Posterior and Medial
  • bring the suture from the posterior glenoid anchor out the speed bridge and apply the intra-articular measurement device
  • Measure the distance between the most posterior and anterior glenoid anchors write down the number. (Medial)
  • Measure the distance between the posterior humeral anchor and the most posterior glenoid anchor and write down the number (Posterior)

7

Prepare graft

  • Draw rectangular diagram on back table with distances of Anterior, Posterior, Medial, and Lateral.
  • Use graft of 3.0mm thickness, human dermal allograft.
  • Add 1cm to each side of the rectangular dimensions created by the anchors.
  • Draw the dimension on the graft and cut out appropriate sized graft
  • have assistant hold the edges of allograft (that will not be used) with hemostat and cut out correct sized graft with very sharp scissors.
  • note the "smooth" and "rough" sides of the graft.
  • the smooth will be superior in the shoulder, rough will be inferior and allow for graft incorporation on glenoid and humerus.
  • Mark graft so medial, lateral, posterior and anterior is known
  • holes can be punched on the location of suture passing.
L

Graft Suture Passing

1

Pass sutures through graft on the outside of shoulder

2

Pass sutures from glenoid on medial aspect of graft

  • Grab and bring the anterior sutures from the glenoid out the passport.
  • Through previously punched holes or use of arthroscopic suture passer, pass the suture from the underside of the graft up, and then down on the anterior medial aspect of the graft (a horizontal mattress stitch).
  • Repeat for the second/third gleoind anchor suture.
  • Be careful of spacing and suture mamagement so not tangled.
  • you now have the pulley sutures to help facilitate pulling the graft into the shoulder
  • with the lateral row sutures in the anterior and posterior canulas, lessens the chance of tangles.

3

Pass sutures from humerus throught lateral aspect of graft

  • Grab and bring out the anterior sutures of the lateral row out the passport.
  • Through previously punched holes or use of arthroscopic suture passer, pass the suture from the underside of the graft up on the anterior lateral aspect of the graft.
  • Grab and bring out the posterior sutures of the lateral row out the passport and repeat passing through graft posteriorly.

4

Deliver SCR Graft Into shoulder

  • Pull the medial pulley sutures coming out of superior portal.
  • Pull the graft right up to the passport
  • Isolate the lateral sutures so they are not tangled
  • Use a kingfisher to grab the medial aspect of the graft.
  • While carefully pulling on medial glenoid pulley sutures and pushing with kingfisher, deliver graft into the shoulder through the passport.

5

Fixation of graft on glenoid

  • With the use of knotless 2.9mm suture anchors, the pulley sutures will pull down and lock the graft medially on the glenoid.

6

Fixation of graft on humerus

  • Cut the tape sutures so they are now 4 separate strands (previously combined when passed).
  • Grab one from anterior the other one from the posterior anchor for lateral fixation.
  • Load the suture tape into the the swivel lock anchor
  • Punch and place with some tension into the posterior lateral aspect.
  • Repeat with the remaining 2 sutures anteriorly on the humerus.

7

Posterior side to side stitches

  • Load free 2-0 fiberwire suture into the arthroscopic suture passer and pass and tie a simple stitch from the infraspinatus to the medial posterior graft.
  • Repeat working medial to lateral (usually 2-3 stitches)
N

Wound Closure

1

Closing the portals and dressing the incisions

  • withdraw the instruments

2

Close the incisions with a single subcuticular stitch

  • use 4-0 monocryl suture

3

Apply steristrips

4

Place dressings

  • place Prowicks sponges that are primed with liquid betadine solution over the incisions
  • place and wrap Prowick dressings over the incision
  • cut the arm portion of the wrap to relieve pressure around the axilla and upper humerus.

5

Place sling

  • support the patients arm in an Ultrasling with abduction pillow.
