Data Trace Editor – Restoration of Length: – may be obtained w/ use of femoral distractor or external fixator placed in distal 1/3 of the tibia and the talus or calcaneus; – two pins are placed perpendicular to the anatomic axis and therefore parallel with the joint surfaces of the tibia; – … Read more
– See: Function and Activity after TKR – Post Operative ROM: – most important factor predicting ultimate ROM is range of motion before surgery; – ref: Range of Motion Correlates with Patient Perception of TKA Outcome. – patients with significant stiffness before surgery will have the most difficulty gaining range of motion; … Read more
– Discussion: – calcium homeostasis is the summation of regulatory feedback systems involved in the control of plasma Ca concentrations; – despite the small quantity of ionized calcium (as compared to the amount of calcium in bone), calcium is maintained in blood at a closely regulated concentration; – rate … Read more

Discussion pigmented villonodular synovitis is a slow growing, benign, and locally invasive tumor of the synovium; location: most often involves the knee (also in hip, ankle, elbow, etc.); always consider PVNS in a younger patient with unexplained hip pain; acute episodic attacks of pain and swelling may occur; patients may have mechanical symptoms (locking and … Read more
– Dicussion: – assess for swelling and tenseness of the forearm compartments; – assess carrying angles of the affected and non affected arms; – r/o neurologic deficits – median nerve injuries are more often associated w/ posteromedial displacement; – … Read more
– Discussion: – wt bearing line of the body normally falls medial to the axis of sub talar joint, & therefore, when the patient stands on one foot, the foot pronates; – when pt rotates leg externally, heel inverts & wt bearing line moves laterally; – total … Read more
