PURPOSE: Local cartilage and bony defects, which are too large for joint preserving cartilage treatment are difficult to treat. The implantation of a mini-resurfacing implant (Hemicap®, 2med, Hamburg, Germany) may be a possible alternative treatment for these patients. This partial replacement fills the defect and restores a smooth and continuous articular surface. The aim of this study was to determine short- to midterm results of the treatment of local cartilage defects of the femoral head using the Hemicap®...

INTRODUCTION: Acromegaly is a rare disorder characterized by excess secretion of growth hormone and its principle mediator, insulin-like growth factor-1. Although acromegaly is frequently associated with osteoarthritis, the outcome of arthroplasty in this population is not documented. CASE REPORT: We report here a case of aseptic loosening of an uncemented total hip arthroplasty acetabulum in an acromegalic patient that was revised with a cemented cup. It has been suggested that the incidence of this complication is increased in other pathology with a similarly high bone-turnover (e...

Being one of the most successful surgeries in the history of medicine, the indications for total hip arthroplasty have widened and are increasingly being offered to younger and fitter patients. This has also led to high expectations for longevity and outcomes. Acetabular cup position has a significant impact on the results of hip arthroplasty as it affects dislocation, abductor muscle strength, gait, limb lengths, impingement, noise generation, range of motion (ROM), wear, loosening, and cup failure. The variables in cup position are depth, height, and angular position (anteversion and inclination)...

Total hip arthroplasty has been utilized for the past 50 years as an effective treatment for degenerative, inflammatory and traumatic disorders of the hip. The design of these implants has generally followed the anatomy of the hip as a ball and socket joint with the femoral head representing the ball and the acetabulum representing the socket. We describe a novel hip arthroplasty design in which the "ball" is located on the acetabular side and the "socket" is located on the femoral side. The results of extensive biomechanical testing are described and document wear and corrosion characteristics that are at least equivalent to standard designs...

INTRODUCTION: Sex determination is the first step in establishing the identity of skeletal remains. Many studies included biometry of posterior features of hip bone. Very few studies are reported involving the biometry of anterior features of the hip bone. Anterior features of hip bone are important especially, if there is damage to the posterior features of hip bone in cases involving deliberate disfigurement of the body to resist identification of the crime in medicolegal cases. AIM: The present study was done to evaluate the effectiveness of anterior border parameters of the hip bone for prediction of sex using discriminant function analysis in South Indian population...

BACKGROUND: Plain radiography, 2-dimensional (2D) magnetic resonance imaging (MRI), and computed tomography (CT) do not precisely display morphology and acetabular coverage in developmental dysplasia of the hip or pincer-type femoroacetabular impingement. Pelvic position and pelvic tilt affect assessment of the acetabular parameters, leading to misinterpretation. OBJECTIVE: We tested a 3-dimensional (3D) CT evaluation script to calculate the crossover sign (COS), acetabular coverage and morphology...

A 12-year-old girl presented with a 1-week history of right hip pain. MRI revealed a lesion in the incompletely fused posterior triradiate cartilage of the right acetabulum with imaging characteristics of an osteoid osteoma. The surgeon requested guidewire placement under CT guidance for lesion drilling. The CT approach was planned to avoid the usual course of the sciatic nerve, and the lesion was successfully removed and confirmed at histology to be an osteoid osteoma. At a follow-up visit, MRI showed no recurrence but demonstrated an abnormal common peroneal nerve from the sciatic notch to the popliteal fossa with denervation oedema in the tibias anterior and peroneal musculature...

INTRODUCTION: Legg-Calvé-Perthes Disease (LCPD) represents idiopathic avascular necrosis of femoral head in pediatric population. Indications for treatment depend mostly on prognosis about femoral head sphericity and hip congruence at the end of growth. The aim of this review is to highline prognostic factors of LCPD. METHODS: Bibliographic search in PubMed allowed selection of 33 articles concerning prognostic factors and/or classification of LCPD. CONCLUSION: Clinical factors of poor prognosis are overweight, female sex, age exceeding 6 years old, and lack of hip abduction...

PURPOSE: In recent times the direct anterior approach for total hip replacement has gained considerable interest among orthopaedic surgeons because of the relative muscle-sparing nature than other surgical approaches. However, critics believe that this approach is associated with steep learning curve and high complication rates, mainly attributed to a more limited exposure to the femur. In order to make femoral access easier and implantation of acetabulum in anatomic plane, we designed a "two incisions anterior approach technique" for total hip replacement...

Objectives The purpose of this study was to validate T2* mapping as an objective, noninvasive method for the prediction of acetabular cartilage damage. Methods This is the second step in the validation of T2*. In a previous study, we established a quantitative predictive model for identifying and grading acetabular cartilage damage. In this study, the model was applied to a second cohort of 27 consecutive hips to validate the model. A clinical 3.0-T imaging protocol with T2* mapping was used. Acetabular regions of interest (ROI) were identified on magnetic resonance and graded using the previously established model...

This work describes a technique of platelet-rich plasma (PRP) infiltration for the treatment of severe hip osteoarthritis (OA). Although the results achieved with intra-articular infiltrations of PRP are promising, they may be insufficient in the long-term for severe hip OA. The technique consists of a combined intra-articular and intraosseous infiltration of PRP to reach all joint tissues, especially the subchondral bone, and hence facilitate a greater distribution of PRP. Diagnosis is based on clinical and radiographic findings, and patients with grade III OA according to the Tönnis scale, as well as patients who have not responded to conventional treatment, are considered candidates for this technique...

An os acetabuli (OA) increases the contact area and surface area of the acetabulum and is important to maintain congruity of the hip joint. Thus preservation of this ossicle is important to prevent loss of contact area and ensure containment of the femoral head. We describe an all-arthroscopic approach to the fixation of OA with a compression screw. Initially, the fibrous tissue is debrided between the acetabular rim and the OA, a guidewire is placed through the OA up to the acetabular rim, and a screw is inserted over the wire...

Hip cartilage injuries are very common, with rates as high as 50% having been reported in some series; abnormal femoral acetabular contact can result in a full-thickness cartilage defect or labral lesion. The prevalence of labral lesions can be as high as 55%. This Technical Note describes an arthroscopic technique to reconstruct an uncontained, full-thickness, focal cartilage defect of the acetabulum, with reconstruction of the missing labrum using a gracilis allograft and use of a biological liquid scaffold for cartilage reconstruction...

Mitsunori Kaya
Cam impingement is caused by jamming of an abnormal femoral head with an increased radius into the acetabulum during motion. Therefore, the elevation of the contact pressure during the motion is suspected to be an essential pathology of femoroacetabular impingement. However, there is no method to quantify the hip contact pressure during motion. The purpose of this Technical Note is to introduce a technique to measure the hip contact pressure during arthroscopic surgery. The author believes that the current technique will be a useful tool for the detailed investigation of the pathophysiology femoroacetabular impingement and thorough evaluation of its therapeutic significance...

A biological screening of sixteen lichen extracts on human HT-29 colorectal cancer cells, led to the selection of Pleurosticta acetabulum, a lichen widely present in tree barks in Europe. Bioguided purification of the acetonic extract resulted in the isolation of cytochalasin E, a common fungal metabolite. This compound is responsible for the anti-proliferative activity of the extract. Its presence in lichens is reported here for the first time. LC-MS quantitation of cytochalasin E in different samples of P...
