BACKGROUND Populations suffering from developmental dysplasia of the hip typically have reduced femoral coverage and experience joint pain while walking. Periacetabular osteotomy (PAO) is one surgical solution that realigns the acetabular fragment. This challenging surgery has a steep learning curve. Existing navigation systems for computer-assisted PAO neither track the released fragment nor o...

OBJECTIVE Treatment of acetabular fractures remains one of the most challenging tasks that orthopaedic surgeons face. An accurate assessment of the injuries and preoperative planning are essential for an excellent reduction. The purpose of this study was to evaluate the feasibility, accuracy and effectiveness of performing 3D printing technology and computer-assisted virtual surgical procedures...

Aim: Pelvic and acetabular fractures are associated with high-energy trauma. The aim of this study was to identify factors that are associated with specific clinical outcomes following treatment for these fractures. Methods: A consecutive series of 30 patients who had surgical intervention for either pelvic or acetabular fractures formed the sample for this study. Clinical variables reviewed we...

BACKGROUND The primary aim of this study was to evaluate the relationship of the migration percentage (a radiographic metric quantifying hip displacement) in children with Gross Motor Function Classification System (GMFCS) level-IV or V cerebral palsy and spastic hip dysplasia to the acetabular index and the health-related quality of life (HRQOL) as measured with the Caregiver Priorities and Ch...

Between 1980 and 2000, 63 support rings were used in the management of acetabular deficiency in a series of 60 patients, with a mean follow-up of 8.75 years (2 months to 23.8 years). There was a minimum five-year follow-up for successful reconstructions. The indication for revision surgery was aseptic loosening in 30 cases and infection in 33. All cases were Paprosky III defects; IIIA in 33 pat...

Thanks to increases in longevity, many joint replacement patients will now live long enough and remain suffi ciently active for their prostheses to require revision surgery after becoming loose. The development of osteoporosis in such patients, however, creates a challenge for the orthopaedic surgeon. Acetabular component revision arthroplasty in patients with poor bone stock requires experienc...

OBJECTIVES This study aims to evaluate short-term results of total hip replacement performed for post-traumatic osteoarthritis and/or femoral head necrosis caused by acetabular fractures. PATIENTS AND METHODS We performed 39 arthroplasties due to acetabular fractures on 25 male and 14 female patients during the course of a five-year period. The mean age of the patients was 45 years (range 25 ...

PURPOSE OF THE STUDY The aim of the study was to compare a radiographic position of the acetabular component with a position guided by the navigation system in final acetabular cup alignment. MATERIAL Between May and October 2005, 15 patients underwent implantation of a cementless acetabular component from the posterolateral minimally invasive approach with the use of kinematic navigation. ...

BACKGROUND Retractor placement is a leading cause of intraoperative nerve injury during total hip replacement (THR) surgery. The sciatic nerve, femoral nerve, and superior gluteal nerve are most commonly affected. This study aimed to identify the distances from bony landmarks in the hip to the adjacent nerves on magnetic resonance imaging (MRI) and the associations between anatomical factors an...
