Acetabular labral and chondral pathology is a very frequent finding during hip surgery and is believed to be responsible for persistent hip pain after sports injuries. The acetabular cartilage and labrum form a complex anatomical structure which provides the appropriate biomechanical features for a harmonic movement between the femoral and acetabular bones. Any factor (structural or acquired) t...

The purpose of this article is to determine normative values for the length of the acetabular rim and detect differences between gender, age, ethnicity, height and leg length. Six measurements were taken on the acetabular rim of 143 cadaveric skeleton specimens (286 acetabula) using a coordinate-measuring device: circumferential (excluding acetabular notch), anterior inferior iliac spine (AIIS)...

In order to help surgeons improve tool insertion accuracy in pelvic-acetabular surgery, it is very important to take advantage of the emerging navigation, guidance and robotics technologies. The computer integrated surgical system is promising for pelvic-acetabular surgery. In most of the procedures of pelvic-acetabular surgery, such as drilling or milling operations, there are many delicate op...

BACKGROUND AND PURPOSE Loss of bone stock remains a challenge in revision hip surgery. Grafting with allograft is well established, but there are problems with availability, cost, infection, antigenicity, reproducibility, and stability of the created construct. BoneSave is a biphasic porous ceramic consisting of sintered 80% tricalcium phosphate and 20% hydroxyapatite. In vitro and in vivo stud...

Uncemented acetabular components are associated with a significant incidence of polyethylene wear and secondary osteolysis. The new tantalum/polyethylene composite (Hedrocel) acetabular component is designed to reduce the polyethylene wear and to increase the longevity of the acetabular cups. We report our short- term clinical outcome and patient satisfaction following use of an uncemented tant...

BACKGROUND Hip resurfacing is an option to consider when treating younger, more active patients. Advantages over total hip arthroplasty include a more normal gait and a lower incidence of thigh pain. METHODS In this prospective study, 190 hip resurfacing procedures (164 participants) were performed using a cobalt-chromium femoral component and a cementless acetabular cup with a 3.8-mm highly ...

We reviewed the medical records of 115 patients with 130 hips with developmental dysplasia with complete dislocation in the absence of a neuromuscular disorder, spontaneous reduction with a Pavlik harness, and a minimum of 14 years' follow-up. The mean age at the time of harness application was 4.8 months (1 to 12) and the mean time spent in the harness was 6.1 months (3 to 12). A total of 108 ...

Introduction: Acetabular dysplasia is common in our country. The experience with periacetabular “Ganz” osteotomy is relatively low. We would like to report our short‐term experience in a small group of patients who received such a surgery. Materials and Methods: In a descriptive study, 15 patients with dysplastic acetabula who had undergone “Ganz” pelvic osteotomy were evaluated for their clini...

AIM To investigate the possible influence of demographic and biomechanical factors on stability of the Endler cementless polyethylene acetabular cup. METHODS This was a retrospective cohort study. Seventy-two patients (25 men, 47 women) bearing 82 Endler prostheses, all of which were implanted by the same surgeon in the period between 1985 and 1991, were invited for a control visit (final vis...
