Remember:
-McMurray circumduction test is used to evaluate individuals for tears in the meniscus of the knee.
-To perform the test, the knee is held by one hand, which is placed along the joint line, and flexed to complete flexion while the foot is held by the sole of the foot with the other hand.
-The examiner then rotates the leg internally while extending the knee to 90 degrees of flexion. If a "thud" or "click" is felt along with pain, this constitutes a "positive McMurray test" for a tear in the posterior portion of the lateral meniscus.

-Patellectomy (in cases of comminuted fracture) is removal of the entire patella, whereas a partial patellectomy is removal of only a portion of the patella, while any ligaments or tendons that had been connected to the removed portion are connected to the remaining portion.

-Osteomalacia occurs because of inadequate mineralisation of bone matrix
-Osteoporosis, the bone is normally mineralised, but deficient in quality, quantity and structural integrity.

•What's the difference between osteoporosis and osteomalasia ?
-In osteoporosis, bone mass decreases, but the ratio of bone mineral to bone matrix is normal.
-In osteomalacia, the ratio of bone mineral to bone matrix is low.

-Breast cancer is the Most common cancer in female .
So always keep it in mind and try to exclude it in any patient presenting with a breast mass and you must perform Triple assessment .
1. Clinical assessment of the mass
2. Imaging ( mammography / ultrasonography )
3. Biopsy ( FNAC / corecut ) .

-Tests done, in suspecting DVT cases:
•MOSE'S sign/ Bancroft's sign - Calf tenderness on direct pressure on calf
•Pratt's sign - Calf tenderness on squeezing from side to side.
•HOMAN'S sign - By forcible dorsiflexion with extended knee / without folding the knee, tenderness felt over calf
•NEUHOF'S sign - Thickening and deep tenderness while palpating deep in calf muscle
•LINTON'S sign - After applying tourniquet at SFJ patient made to walk +/- removal of tourniquet -> prominent superficial veins observed.

Needle biopsy/Cytology
◼️Histology can be obtained under local anaesthesia using a trucut or corecut biopsy device.
◼️Biopsy can give definitive preoperative diagnosis and can differentiate between duct carcinoma in situ (DCIS) and invasive disease, and can provide staining of the tumor for receptor status which is important for planning on neoadjuvant therapy.
◼️Fine needle aspiration cytology (FNAC) is the least invasive cell based diagnostic tool, it is very accurate if both the operator and cytologist are experienced, however false negative can still occur mainly due to sampling error, also FNAC cannot differentiate between in situ disease and invasive disease.
◼️Above figure is fine needle aspiration cytology showing grade III ductal carcinoma cells.

Brown tumor:
-The brown tumor is a bone lesion that arises in settings of excess osteoclast activity, such as hyperparathyroidism.
-They are a form of osteitis fibrosa cystica.
-It is not a neoplasm, but rather simply a mass. It most commonly affects the maxilla and mandible, though any bone may be affected.
-Brown tumours are radiolucent on x-ray.
