Biomechanical evaluation of transverse acetabular
fracture fixation, Clinical Orthopaedics and Related Research 352(7): 215-222.
The back of the acetabular
cup was fixed and this boundary condition was propagated to all the 16 steps.
The ASR(TM) XL Acetabular
System was first launched in 2004 and has been available worldwide.
The iliac vessels, which had been compressed by the displaced acetabular
cup and screws, were secured with vascular slings.
The first project step was the design of the acetabular
cup's trabecular structure, which was done in cooperation with the group of orthopedic surgeons that Adler Ortho work with.
Edema and fat necrosis in the acetabular
region results in a reduced T1 signal, whereas T2 signals are increased due to osteopenia.
The occurrences of tears in the athlete's acetabular
labrum have been reported in sports that place rotational demands on the hip (such as tennis, golf, and hockey) (Binningsley, 2003; Mason, 2001; McCarthy et al.
This results in the abnormal contact, or impingement, between the femoral neck and acetabulum, leading to the degenerative changes in the acetabular
labrum and/or adjacent articular cartilage.
A recent study found that manual acetabular
cup placement fell within the acceptable safe range only 50% of the time.
The commonly recognized causes of posterior hip instability include hyperlaxity, acetabular
or femoral retroversion, bony or ligamentous lesions of the acetabulum, or following trauma or arthroplasty.
It allows reliable measurements of acetabular
coverage, femoral neck anteversion, and the appearance and position of the femoral head.
NYSE: ZMH; SIX: ZMH), a leader in musculoskeletal care, will be showcasing its extended Acetabular
Cup portfolio at this year's EFORT (European Federation of National Associations of Orthopaedics and Traumatology) Congress in Madrid, Spain.
