What is a trochanteric flip osteotomy?
The trochanteric flip approach uses an osteotomy of the greater trochanter, leaving the vastus lateralis and gluteus medius muscles attached to the fragment. The trochanteric fragment is flipped anteriorly, with mobilization of the gluteus medius and minimus muscles from the underlying structures.
What is a Digastric osteotomy?
The trochanter osteotomy (digastric slide), through either the Kocher-Langenbeck or Gibson interval, can be combined with surgical dislocation of the hip to allow direct articular access. The maintenance of knee flexion (at 90°) and hip extension throughout the procedure reduce tension on the sciatic nerve.
What is the greater trochanter of the femur?
Anatomical terms of bone The greater trochanter of the femur is a large, irregular, quadrilateral eminence and a part of the skeletal system. It is directed lateral and medially and slightly posterior. In the adult it is about 2-4 cm lower than the femoral head.
Why is trochanter important?
The position of the greater trochanter influences the mechanical stress of the hip joint, the extent of contraction of the gluteus medius and minimus muscles, and the mechanical stress of the femoral neck.
Is trochanter a bone?
A trochanter is a tubercle of the femur near its joint with the hip bone. In humans and most mammals, the trochanters serve as important muscle attachment sites….

Is greater trochanteric pain syndrome a disability?
GTPS appears to confer levels of disability and quality of life similar to levels associated with end stage hip OA.
What is the purpose of the trochanter?
A trochanter is a tubercle of the femur near its joint with the hip bone. In humans and most mammals, the trochanters serve as important muscle attachment sites.
