E-Cadherin connected to actin filaments.

• Lateral Meniscus
• Medial Collateral Ligament
• Anterior Cruciate Ligament

• Tendon of Supraspinatous most commonly affected.
• Pain anterior and superior to glenohumeral joint during abduction.

• Freq. Inferior than Anterior
• Can strech axillary or radial nerve

• Axillary Nerve Lesioned
• Circumflex humeral artery lacerated.

• Detachment of rotator cuff muscles.
• Remaining rotator cuff muscle (subscapularis) mediallry rotates humorous.

• Radial Nerve lesion
• Profound brachial artery laceration

• Contraction of tricep and brachialis
• Median nerve is lesioned

• Separated into Median and Ulnar distributions
• Flex MCPs
• Extend PIP and DIPs

Type I = The Better Kind! Why? Because this is the kind you have. Red fibers, use mitochondria. Slow twitch.

Type II = Fast twich, anerobic.

It is a bone growth associated with Gardner's Syndrome, which is a subset of FAP.

It is a interlacing trabeculae of woven bone surrounded by osteoblasts found in proximal tibia and femur. Most common in men < 25.

Same osteoid osteoma, but found in vertebral column.

• Also called giant cell tumor.
• Occurs most frequently at epiphyseal ends of long bones. Peak incidence 20-40 years.
• Locally aggressive benign tumor often around the distal femur, proximal tibial region. Knee.
• Characterstic double bubble or soap bubble appaearance on xray.
• Spindle shaped multinucleated giant cells on histology.

• Most common benign bone tumor. Mature bone with cartilaginous cap. Usually in men <25 years old. Commonly orignates from long metaphysis.
• Rarely transforms to malignant chondrosarcoma

Beningn cartilationous neoplasm found in intramedullary bone. Usually distal extremeties (contrast with Osteosarcoma which is around the knee!!)

• 2nd most common primary malingant tumor of bone after MM.
• Peak incidence men 10-20 years.
• Found in metaphysis of long bones around knees.
• Risk factors: Paget's disease, bone infarcts, radiation, famililal RB.
• Poor prognosis

• Codman't triangle/sunburst pattern on Xray
• 

• Anaplastic small blue cell malignant tumor.
• Most common in boys < 15.
• Ewings and onion rings onion skin appearance in bone.
• Think
• t(11;22) 11+22=33 Patrick Ewing's Jersey Number

• Malignant Cartilagionous tumor. Most common in men age 30-60. Usually located in pelvis spine, humerus tibia and femur.
• Can derive from osteochondroma.

• Uric Acid: Parallel Light = Yellow
• Perpendicular Light = Blue

• Pseudogot (calcium pyrophosphate crystals)
• Parallel Light = Blue
• Perpendicular Light = Yellow
