Across: 1 - In addition to #23 across and the medial meniscus, this structure is often coinjured as part of the “unhappy triad” (acronym) MCL. Medial collateral ligament. 3 - Antibiotics are always indicated in this type of fracture OPEN. Infection risk is high. 6 - This gruesome intervention may be limb saving in patients with a painful swollen limb and paresthesias, pulselessness, paralysis, and poikilothermia FASCIOTOMY. The “P’s” of compartment syndrome are well known. Poikilothermia is loss of normal temperature regulation. 8 - A patient who develops hand pain and numbness after holding the wrist in forced flexion for 60 seconds may have this (acronym) CTS. Carpal tunnel syndrome. Compression of the median nerve as it travels through the wrist. The sign described is called Phalen sign. 10 - Atrophy of this group of muscles is a late sign of #8 across THENAR. The thenar muscles are innervated by the median nerve. The hypothenars by the ulnar. 11 - What study should be ordered in a patient with new onset back pain and urinary incontinence? (acronym) MRI. This may be a case of cauda equina syndrome, a neurosurgical emergency. 13 - Fracture of this bone should be suspected in a patient with snuff box tenderness SCAPHOID. Even if the x-ray is negative, treat presumptively for fracture. X-ray may take 2 weeks to show fracture. Avascular necrosis is a complication. 15 - Most common type of hip dislocation POSTERIOR. May occur when a knee hits the dashboard. 17 - An old man with leg pain that gets better when leaned forward or walking uphill: Spinal STENOSIS This is called neurogenic claudication. Flexion of the spine opens the spinal canal and relieves nerve root compression. 19 - Your roommate was out drinking on Saturday night and awoke on Sunday with a wrist drop. He has injured the RADIAL nerve Aka “Saturday night palsy.” The mechanism usually involves passing out with the humerus in an awkward position compressing the radial nerve. Most cases resolve in time. 20 - Your patient with an L5–S1 disc herniation may have a diminished ACHILLES reflex Herniation at that level typically affects the spinal nerve root one level below. 22 - A person defending himself from an attack may end up with a fracture of this bone ULNA.

May be infected, or not.

Down: 2 - Most commonly fractured long bone CLAVICLE 3 - Radiographic new bone formation in a sunburst pattern is a sign of this devastating tumor OSTEOSARCOMA 4 - An obese adolescent male with knee pain and limp may have epiphyseal displacement on this bone FEMUR. Slipped capital femoral epiphysis is separation of the femoral head along the growth plate. Often the pain is referred to the knee. 5 - A patient with a femur fracture suddenly develops SOB, rash, DIC, and cardiovascular collapse (two words) FAT EMBOLI 7 - Most common type of shoulder dislocation ANTERIOR 9 - Mike Tyson presents with hand pain after a match.

Disease is known as developmental dysplasia of the hip or congenital hip dysplasia. All newborns are screened by physical examination maneuvers at every well visit in the first year of life. Failure to diagnose and treat results in early onset of osteoarthritis and early disability. 16 - Falling on outstretched hand most likely results in fracture of this bone RADIUS 18 - Hormone level that should be checked in #4 down TSH. Thyroid-stimulating hormone. Hypothyroidism is an associated condition. 20 - The AXILLARY artery and nerve may be injured in #7 down 21 - SEPTIC arthritis: Must be ruled out in any patient with a red, hot joint 23 - What ligament is injured in a patient with excess laxity on anterior translation of the tibia?

Across: 1 - Most common type of thyroid carcinoma PAPILLARY. And a highly favorable prognosis. Five-year survival >95%. 2 - A patient in diabetic ketoacidosis is always total body deficient in this electrolyte (regardless of serum level) POTASSIUM. In fact these patients are usually hyperkalemic due to intracellular shifts due to lack of insulin and acidosis. 3 - Osteoporosis is defined by a T-SCORE of –2.5 or lower on DEXA scanning The T-score is the number of standard deviations below the mean for a healthy young adult. 7 - Hyponatremia and hyperkalemia should always prompt consideration of this life-threatening problem ADRENAL INSUFFICIENCY. Especially in a patient on chronic exogenous steroids. 9 - Intermediate-acting insulin, usually dosed twice daily NPH. May also provide basal coverage, though not technically peakless. 11 - Rarely checked, but often elevated antibody in Hashimoto thyroiditis ANTI-TPO. Thyroid peroxidase. 13 - Agonists to this neurotransmitter are first-line therapy for prolactinoma DOPAMINE. Bromocriptine for example. 16 - Long-acting insulin without a peak GLARGINE. Used to provide basal insulin. 18 - Classically, only Type 1 diabetes mellitus presents with this life-threatening disorder KETOACIDOSIS. Insufficient insulin causes cells to switch to fat as energy source, producing ketoacids as a byproduct. 20 - Most aggressive and rapidly fatal thyroid carcinoma ANAPLASTIC. Five-year survival rate is 5% to 10%. 25 - “Stones, bones, groans, and psychiatric overtones” may represent this electrolyte disturbance HYPERCALCEMIA 27 - The first step in evaluation of suspected hyperaldosteronism is measurement of the plasma RENIN: Aldosterone ratio 28 - Type 1 diabetics will always require therapy with this at all stages of their disease INSULIN. Unlike Type 2 diabetics who may remain insulin independent for many years/life. 29 - This drug, more commonly used in variceal upper GI bleeding, is also used to treat acromegaly OCTREOTIDE. A somatostatin analog that lowers portal venous pressure. 30 - Use of this drug class in diabetes has been shown to decrease progression of nephropathy ACE INHIBITORS. And is generally recommended for secondary prevention of renal disease in diabetics.

Down: 1 - Antithyroid drug preferred for treating hyperthyroidism in pregnancy PROPYLTHIOURACIL 4 - This treatment is by far and away the most important initial treatment for hypercalcemia SALINE. By IV infusion. 5 - This test along with a thyroid scan can help differentiate Graves disease from thyroiditis (acronym) RAIU. Radioactive iodine uptake. Elevated uptake is indicative of a hypermetabolic gland (Graves) whereas decreased uptake indicates gland destruction (thyroiditis). 6 - Hemorrhagic necrosis of the adrenal gland may occur after infection with this bacteria MENINGOCOCCUS. Aka, Neisseria meningitidis. 8 - This syndrome should always be suspected in a patient with hypertension and hypokalemia CONN. Primary hyperaldosteronism. 10 - Adverse effect of nearly all antiglycemic agents except metformin HYPOGLYCEMIA 12 - Antithyroid drug preferred in absence of pregnancy METHIMAZOLE 14 - In the absence of contraindications, this drug is the absolute first-line therapy for Type 2 diabetes METFORMIN 15 - The clinical finding of bitemporal hemianopsia would prompt one to order MRI of this structure SELLA. Tumors of the pituitary gland may encroach upon the optic chiasm and cause this clinical presentation. 17 - Presence of this antibody is highly specific for Graves disease (acronym) TSI. Thyroid-stimulating immunoglobulin. Antibody binds to the TSH receptor, causing unregulated production of thyroid hormone. 19 - Rare but serious side effect of metformin LACTIC ACIDOSIS. A Type B lactic acidosis, where there is no tissue ischemia. 21 - Fastest acting insulin LISPRO. Used for prandial coverage. 22 - Best screening test for assessing thyroid function (acronym) TSH. Thyroid-stimulating hormone. A normal TSH excludes thyroid dysfunction, regardless of T3 or T4 levels. 23 - Insulin therapy in diabetic ketoacidosis is directed at lowering (glucose/ketones) KETONES. The primary problem in DKA is insulin deficiency and the resultant acidosis that results from using fats rather than glucose as an energy source. Hyperglycemia is merely a sign of the problem, but not the problem itself. 24 - A patient with positive urinary metanephrines should never been given a drug from this class alone BETA-BLOCKER. Blockade of the beta receptors in the periphery may lead to unopposed alpha adrenergic activity and severe vasoconstriction and hypertension. A similar effect may occur in a patient with cocaine on board. 26 - Psychotropic drug often implicated in nephrogenic diabetes insipidus LITHIUM
