vascular supply to the humeral head Two Part Articular Segment Displacement fracture plane is through the anatomic (not surgical neck); anatomic neck represents the old eiphyseal plate; surgical neck represents the weakened area below the tuberosities and head approximately 2 cm distal to the anatomic neck; significant chondral defects and minimally separated fragments may go … Read more
(See: – Pediatric Lateral Condyle Frx) Discussion frxs of lateral condyle that involve capitulum alone or extend medially to involve the lateral portion of trochlea; see capitellum fracture Lateral approach » typically the plate is positioned posteriorly, and can be placed if needed as far as the posterior aspect of the capitellum; remember that the … Read more
– Fractures Subtypes: – capitellar and coronal shear frx – distal humeral frx – lateral condyle frx – medial condyle frx – Muller’s Classfication: – type A: extra-articular fracture; – type B: uni-condylar fracture; – type C: bi-condylar fracture; – controversies: – total elbow replacement – Distal humeral fractures treated with noncustom total elbow … Read more
– Technique: – it is helpful to have the patient paralyzed during the reduction (requires general anesthesia); – anatomic reduction of the condyles is performed first; – remember that the common factor in fixation failure in these fractures is comminution and/or osteoporosis; – best-fit method: … Read more
– Discussion: – refers to a condition in which the shoulder capsule becomes contracted and thickened; – patients note a dramatic decrease in shoulder ROM; – in many cases there is spontaneous resolution after 1-3 years and motion is re-gained; – associated disorders: – cervical spondylosis – hypothyroidism – ref: Prevalence of hypothyroidism in patients … Read more
– Technique Considerations: – following restoration of fracture anatomy, contour 1/3 tubular, 3.5 pelvic reconstruction, or 3.5 DCPs, to fit medial and lateral aspect of distal humerus; – the strongest bone lies along medial and lateral columns and therefore the plate screws should be placed here rather than central portion of distal end of the … Read more
(see also: Bone Tumor Menu) Discussion myeloma is malignant tumor of plasma cells arising from a single clone; multiple myeloma accounts for > 40% of primary malignant tumors of bone. it is most common malignant primary tumor of bone may arise as single intraosseous tumor but more often it develops as multiple painful lesions throughout … Read more
