Reverse Hill Sachs

Peripheral Vertical Longitudinal Tear Posterior Labrum

Quadrilateral Space Syndrome

Pearls from Stoller Macau April 2011 - 9. Elbow

1. Anatomical Variants
• pseudo defect of trochlea
• transverse trochlea ridge
• pseudo defect of capitellum (post on coronal)
2. Valgus injury (throwing) - tension medial side, compression lateral side
3. "T sign" - partial tear anterior bundle MCL distally
4. Medial Anatomy - PT, FCR, FDS
5. Lateral Anatomy - ECRB (most common tendon involved), EDC, ECU
6. Lateral - 3 ligaments - LCL, LUCL (attaches to supinator crest of ulna distally), annular ligament
7. Biceps tear - if partial need to state wether under or over 50%
8. Lacertus fibrosis - medial to biceps on axial; prevents proximal "slingshot" of torn biceps 
9. Anconeus epitochlearis

Pearls from Stoller Macau April 2011 - 8. Wrist

1. Coronal plain most NB
2. GRE for TFCC
3. Extrinsic ligaments ["volar extrinsic ligaments"]- rarely torn (RSC, RLT, RSL)
4. SL Ligament complex - 3 components - dorsal (strongest), middle (weakest), volar
5. LT Ligament complex - 3 components - d, m , v(strongest)

Pearls from Stoller Macau April 2011 - 7. Muscle

1. Direct Injury - contusion, laceration, haematoma
2. Indirect injury- strain or tear
3. Myositis Ossificans - peripheral calcification - do a CT
4. DOMS
