Jan 1, 2024 · gluteus medius serves as the major hip abductor muscle; insufficiency/tear leads to Trendelenburg gait gluteus maximus and/or fascia lata transfers can be utilized in chronic abductor insufficiency Restoration of offset

May 1, 2009 · Femoral offset is the distance from the center of rotation of the femoral head to a line bisecting the long axis of the femur (Fig. 1). This radiographic measurement should be accurately performed and varies according to the hip rotation. Offset (range, 41 to 44 mm) increases with the size of the femur showing a good correlation coefficient [1 ...

Offset in THA correlates to abductor muscle function, wear, and impingement. Femoral offset after THA is not independent of the cup center of rotation (COR) so hip offset, a combination of femoral offset and change in hip COR, becomes the important measurement.

Dec 4, 2021 · Femoral offset is used for quantitative characterization of hip morphology and is in particular used for preoperative planning of hip endoprosthesis. Restoring femoral offset is considered to be important for the stability of total hip arthroplasty 2 .

Research on total hip arthroplasty (THA) surgery agrees that increasing femoral offset up to 5 mm could improve functional outcome measures. The literature indicates that global offset is a key parameter that physicians should restore within 5 mm during surgery and avoid decreasing.

Feb 13, 2024 · Acetabular and femoral offset play an important role in total hip arthroplasty (THA) for postoperative stability and biomechanical function. However, it is unknown whether offset impacts patient-reported outcomes (PROs).

Background: Offset in THA correlates to abductor muscle function, wear, and impingement. Femoral offset after THA is not independent of the cup center of rotation (COR) so hip offset, a combination of femoral offset and change in hip COR, becomes the important measurement.

Feb 8, 2025 · Hip offset is a crucial measurement in total hip arthroplasty (THA), defined as the perpendicular distance from the teardrop through the femoral head center of rotation (COR) to the femur's axis. This measure combines both acetabular and femoral offsets.

Hip offset reconstruction was directly related to the position of the hip COR, and navigation allowed quantitative control of offset and hip length. The principle of total hip arthroplasty (THA) is to recreate the correct articulation of the hip which has become destroyed by arthritis.

Hip resurfacing decreases offset without effect on function. Modular neck and computer assistance may improve intraoperative calculation and reproduction of femoral offset. Increasing offset with a standard cemented design may decrease long-term fixation.
