IOT Day 2 study cards

Vocabulary flashcards covering rotator-cuff anatomy, tear patterns, repair techniques, tenodesis options, augmentation, and biologics.

Rotator Cuff

Group of four shoulder muscles (subscapularis, supraspinatus, infraspinatus, teres minor) that stabilize the glenohumeral joint.

Subscapularis

Originates on subscapular fossa, inserts on lesser tuberosity; functions in internal rotation of the shoulder.

Supraspinatus

Originates on supraspinous fossa, inserts on greater tuberosity; initiates shoulder abduction.

Infraspinatus

Originates on infraspinous fossa, inserts on greater tuberosity; provides external rotation.

Teres Minor

Originates on infraspinous fossa, inserts on greater tuberosity; primary external rotator above 90° of abduction.

Rotator Cable

Thick fibrous bundle in the cuff that transmits force across the tendon like a suspension bridge.

Crescent Tear

Rotator-cuff tear that is short and wide; typically amenable to straightforward repair.

L-Shape / Reverse L-Shape Tear

Long, narrow tear (length > width); repaired with side-to-side sutures (margin convergence) plus lateral anchors.

U-Shape / Longitudinal Tear

Long, narrow cuff tear with greater medial-lateral length; treated with margin convergence and lateral anchors.

Retracted Tear

Complete cuff tear with tendon retracted, scarred, and often showing atrophy and fatty infiltration.

Delaminated Tear

Horizontal split of the cuff tendon creating articular and bursal layers.

SpeedBridge

Double-row cuff repair using two medial and two lateral SwiveLock anchors; up to three FiberTapes per eyelet.

Fibertak SpeedBridge

All-suture anchors (2.6 mm) available double or triple-loaded; smaller footprint allows more anchors vs 4.75 mm screws.

Ripstop (cuff repair)

Suture configuration that prevents suture cut-through at the tendon edge.

SpeedFix

Single-row rotator-cuff repair technique using a 1:1 suture-to-anchor ratio.

Punch (instrument)

Creates pilot hole for cuff anchors; also used to ‘pop’ cortical bone if anchor insertion is difficult.

4.75 Anchor

Standard SwiveLock screw anchor size commonly used for lateral row fixation.

Scorpion Needle

Arthroscopic suture-passing device; avoid piercing the biceps tendon when using for cuff repair.

PASTA Repair

Partial-articular supraspinatus tendon avulsion; thinner line on Fibertak inserter denotes depth for transtendon repair.

Biceps Tenodesis

Surgical fixation of the long head of biceps to humerus; preserves length-tension and avoids Popeye deformity.

Loop-N-Tak

Onlay tenodesis construct; tendon pierced distal to suture loop to prevent slippage.

KL Fibertak

All-suture onlay tenodesis anchor with pre-converted white loop; tension blue suture before white.

TensionTight Button

Knotless button for onlay tenodesis; uses #5 FiberLink, 225 N load with <1 mm displacement, black line faces patient.

Tenotomy

Biceps treatment involving simple release; faster but higher risk of Popeye deformity, pain, and cramping.

Tenodesis

Cut and fix the biceps; better postoperative strength and lower deformity rates than tenotomy.

Inlay Tenodesis

Tendon fixed inside bone socket; stronger but more risk of cramping and deformity.

Onlay Tenodesis

Tendon fixed on bone surface with smaller anchors; gives predictable tension and less tendon damage.

CuffMend

Arthroscopic augmentation system; requires ≥10 mm passport cannula, lateral mattress stitches, medial FiberWire.

FiberStitch

All-suture anchor (12 mm depth stop) used in cuff augmentation; similar to knee application.

ROHI Score

Guides use of augmentation (

BioTuberplasty

Procedure for irreparable cuff tears placing graft to prevent humeral head–acromion contact.

Angel System

Automated PRP device (40–180 mL) using laser sensor to separate blood components.

BoneSync

Calcium-phosphate putty (1 cc mixed with 1 mL saline) for anchor site augmentation; strongest fixation at 24 h.

ArthroFlex

Acellular human dermal allograft (>97 % DNA removed) used in biologic augmentation of rotator-cuff repairs.
