2 lip 2020 · In the standard anatomical position (with palms faced anteriorly), the ulna lies medially, but the radius is lateral. The anterior aspect of the right ulna. The list of terms: – Trochlear notch. – Coronoid process. – Radial notch. – Ulnar tuberosity. – Body of ulna. – Anterior margin.
27 mar 2024 · To determine ulnar variance on radiographs, the generally accepted standard view is a posteroanterior view obtained with the wrist in neutral forearm rotation, the elbow flexed 90° and the shoulder abducted 90°. Positive variance occurs when the level of the ulna is >2.5 mm beyond the radius margin at the distal radioulnar joint (DRUJ).
19 wrz 2021 · The ulna (plural: ulnae) is one of the two long bones of the forearm, located medially in the supinated anatomic position. It has a larger proximal end and tapers to a smaller distal end (opposite to the radius). Gross anatomy. Osteology. Prominent features of the ulna include:
21 maj 2020 · We described the anatomy of the ulna with special attention to the configuration of the proximal ulna using a large cohort of 100 individual bones based on CT scans. Information about the relevant angles and proportions of the proximal ulna as well as the diameter of the medullary canal of the ulna shaft were provided and statistically analysed.
24 lip 2023 · The ulna is one of the two forearm long bones that, in conjunction with the radius, make up the antebrachium. The bone spans from the elbow to the wrist on the medial side of the forearm when in anatomical position. In comparison to the radius, the ulna is described to be larger and longer.
30 paź 2023 · The radius and ulna are long bones that make up the forearm, extending from the elbow to the wrist. In the anatomical position, the radius is found in the lateral forearm, while the ulna is found in the medial forearm.
1 sie 2012 · The angulation of the proximal and middle ulnae in the frontal and sagittal planes (varus and anterior deviation) was measured in the 3D reconstructed mode. The varus angulation was measured between the axis of the olecranon (line defined by points 3 and 4) and the ulna midshaft axis as presented in Figure 2.
