What is a hemi hip arthroplasty?
A hemiarthroplasty is a half of a joint replacement. “Hemi-“means half and “-arthroplasty” means joint replacement. A hemiarthroplasty is a rare surgery that is only performed under unique circumstances. Replacing half of a hip joint is usually done after rare traumatic injury in which the femoral head is fractured.
What is trabecular pattern?
Trabecula is a supportive and connective tissue element which form in cancellous bone. Trabeculae develop in a normal bone and also in a healing bone. The trabecular pattern of growth follows the course of stress lines along the bone and maximum trabeculae develop along the lines of maximum stress.
What is Pertrochanteric fracture?
Pertrochanteric femoral fractures are a subtype of trochanteric fractures involving the femur. They are one of the most common fractures in old patients. They can involve both the greater and lesser trochanter and are a type of extracapsular fracture.
What is bipolar arthroplasty?
This surgical procedure replaces the head of a damaged femur with an implant designed to stabilize the femur and restore hip function. Unlike total hip replacement, in which both the ball of the femur and the hip socket are replaced, in this procedure, only the ball is replaced.
What is the trabecular pattern of a healing bone?
Trabeculae develop in a normal bone and also in a healing bone. The trabecular pattern of growth follows the course of stress lines along the bone and maximum trabeculae develop along the lines of maximum stress.
What does Garden classification of femoral neck mean?
The Garden classification incorporates displacement, fracture completeness, and relationship of bony trabeculae in the femoral head and neck. Gardens’ originally reviewed 80 patients with femoral neck fractures, which he classified in Types I to IV, and he followed these patients for at least 12 months postoperatively.
Which is the Garden classification for hip fractures?
Garden classification of hip fractures. The Garden classification of subcapital femoral neck fractures is the most widely used. It is simple and predicts the development of AVN 1,2. Garden described particular femoral neck and acetabular trabeculae patterns which can assist in recognizing differences within this classification system 2.
Where is the principal tensile trabeculae located?
Principal tensile trabeculae. it is in the form of an arc. extends from the lateral margin of the greater trochanter to the inferior aspect below the fovea. the arc traverses through the superior cortex of the neck and the femoral head.
