Borderline: 69° to 82° in men, 51° to 56° in women; Pathological: ≥83° in men and ≥57° in women; Femoral head-neck offset Measured in cross-lateral view. Offset of the femoral head with regard to most prominent aspect of the femora neck >10 mm Offset percentage Femoral head-neck offset related to femoral head diameter >0.18
A central venous catheter (CVC), also known as a central line (c-line), central venous line, or central venous access catheter, is a catheter placed into a large vein. It is a form of venous access. Placement of larger catheters in more centrally located veins is often needed in critically ill patients, or in those requiring prolonged ...
The femoral vein is often used to place a central venous catheter, or line for venous access. Ultrasound imaging for locating the vein and catheter placement is advocated over the use of anatomical landmarks due to the possible presence of anatomical variants. [23] [24] [25] This is associated with a significant risk of infection. [25] [26]
Common sizes of femoral heads are 28 mm (1.1 in), 32 mm (1.3 in) and 36 mm (1.4 in). While 22.25 mm (7 ⁄ 8 in) was common in the first modern prostheses, now even larger sizes are available from 38 to over 54 mm. Larger-diameter heads lead to increased stability and range of motion whilst lowering the risk of dislocation. At the same time ...
Gray1146: Femoral vessels as they pass under the inguinal ligament. The femoral vessels are those blood vessels passing through the femoral ring into the femoral canal [1] thereby passing down the length of the thigh until behind the knee. These large vessel are the: Femoral artery (also known in this location as the common femoral artery) and ...
Posterior dislocations is when the femoral head lies posteriorly after dislocation. [5] It is the most common pattern of dislocation accounting for 90% of hip dislocations, [5] and those with an associated fracture are categorized by the Thompson and Epstein classification system, the Stewart and Milford classification system, and the Pipkin system (when associated with femoral head fractures).
A peripherally inserted central catheter (PICC or PICC line), also called a percutaneous indwelling central catheter or longline, [1] is a form of intravenous access that can be used for a prolonged period of time (e.g., for long chemotherapy regimens, extended antibiotic therapy, or total parenteral nutrition) or for administration of substances that should not be done peripherally (e.g ...
The superior-lateral coverage of the femoral head. >20° (<55 years old) [notes 2] <24° (>55 years old) [notes 2] >40° indicates overcoverage; Reimer's migration index [9] The percentage of the femoral head that lies outside of the acetabular roof. It is also called the femoral extrusion index. <25% Tönnis angle
