What Is hip lateralization?
Lateralization of the hip center of rotation is measured relative to the radiographic “U-landmark”, or relative to the pelvis median axis if radiographically possible. The height of the hip center is measured relative to the bi-ischiatic line or to the bottom of the radiographic “U-landmark”.
What is modular hip?
The modularity in total hip arthroplasty (THA) allows orthopaedic surgeons for an exact reconstruction of hip biomechanical parameters especially in revision and tumor arthroplasty. Modular structured femoral stems using taper junctions showed increased implant breakage in the recent past.
What is offset in hip?
The important measure of offset incorporates both the cup and femur, and we call this “hip offset” and define it as the perpendicular distance from the teardrop through the femoral head COR to the axis of the femur (Fig. 1).
What causes COXA Vara?
The most common cause of coxa vara is either congenital or developmental. Other common causes include metabolic bone diseases (e.g. Paget’s disease of bone), post-Perthes deformity, osteomyelitis, and post traumatic (due to improper healing of a fracture between the greater and lesser trochanter).
What is a modular femoral stem?
Abstract. Background: Modular femoral stems are one option for revision THA surgeons and allow offset restoration, leg length discrepancy correction, and stability independent of distal stem fixation. The complexity of revision THA usually leads surgeons to use multiple revision hip designs to address these issues.
Can you fix coxa vara?
Surgical correction of coxa vara in various pathologies can be done successfully with the Hilgenreiner-epiphyseal angle corrected to ≤ 35 degrees or the neck shaft angle corrected to > 120 degrees in order to prevent recurrence of the deformity. Majority of the patients were reported improvement of hip function.
What is femoral head-neck offset?
Femoral head-neck offset is used for quantitative characterization of the femoral head-neck junction, in particular in the setting of suspected femoroacetabular impingement for the detection of cam morphology and preoperative planning.
How do you fix acetabular retroversion?
As the underlying problem with acetabular retroversion is one of the hip joint being malpositioned, it may require correction with surgery. Having an acetabular retroversion treatment may involve either arthroscopic trimming of the bone, or osteotomy (cutting the pelvis and realigning it).
Is acetabular retroversion painful?
However, some patients may develop symptoms due to the femur (thighbone) abnormally hitting the pelvis, or instability from the femoral head slipping backwards out of the hip joint. Common symptoms include: Hip Pain.

What kind of material is the head of a hip made of?
… head was also used in 11 hips with smaller acetabular shells. The acetabular component was a Bencox® cup (Corentec, Seoul, Korea), a hemispheric titanium alloy cup with plasma-sprayed with microporous pure titanium.
