Femoroacetabular impingement (FAI) is a condition in which subtle deformities of the femoral head and acetabulum (hip socket) result in pathological abutment during hip motion. FAI is a common cause of hip pain and can lead to acetabular cartilage damage and osteoarthritis. For some patients with FAI, surgical intervention is indicated, and it can improve quality of life and potentially delay the onset of osteoarthritis. For other patients, however, surgery is contraindicated because significant cartilage damage has already occurred...

Background Femoroacetabular impingement (FAI) describes a painful, abnormal (bony) contact between the femoral neck and acetabulum, which, if left untreated, contributes to early osteoarthritis (OA) of the hip. Despite its flat learning curve and long operation times, hip arthroscopy has been used increasingly often in recent years in the surgery of femoroacetabular impingement. The mini-open technique (MOT) offers a possible alternative that addresses the abnormal morphological prominence and allows minimally invasive clearance of hip motion...

OBJECTIVES: The effects on health related outcomes of a newly-developed rehabilitation program, called 'supported Fast Track multi-trauma rehabilitation service' (Fast Track), were evaluated in comparison with conventional trauma rehabilitation service (Care as Usual). METHODS: Prospective, multi-center, non-randomized controlled study. Between 2009 and 2012, 132 adult multi-trauma patients were included: 65 Fast Track and 67 Care as Usual patients with an Injury Severity Score ≥16, complex multiple injuries in several extremities or complex pelvic and/or acetabulum fractures...

: Marginal impaction of the acetabulum is typically accessible through fracture planes specific to the nature of the injury. Infrequently, however, incarcerated marginal impaction or free osteochondral fragments are not accessible through these existing fracture planes. As such, alternative methods to access these articular pieces must be considered to ensure adequate reduction. We describe an osteotomy of the posterior wall to access incarcerated fragments and marginal impaction of the acetabulum, enabling concentric articular reduction...

The coxal bone shows a very high degree of sexual dimorphism both morphologically and metrically. However, despite a number of recent studies on sex estimation from the skeleton in Thailand, no osteometric methods of sexing the Thai os coxa have been proposed. Therefore, the aim of this study was to develop a standard sex estimation method for a Thai population by examining the efficacy of six coxal bone measurements and eight indices obtained from 200 Thai skeletons. Independent samples t-tests revealed statistically significant differences between males and females for all but one of the measurements...

OBJECTIVES: Osteosynthesis of anterior pubic ramus fractures using one large-diameter screw can be challenging in terms of both surgical procedure and fixation stability. Small-fragment screws have the advantage of following the pelvic cortex and being more flexible.The aim of the present study was to biomechanically compare retrograde intramedullary fixation of the superior pubic ramus using either one large- or two small-diameter screws. MATERIALS AND METHODS: A total of 12 human cadaveric hemipelvises were analysed in a matched pair study design...

Periprosthetic acetabular fractures in geriatric patients are rare injuries; however, the incidence is increasing because of the current demographic developments. For diagnosis of periprosthetic acetabular fractures, conventional X‑ray images are regularly complemented by computed tomography (CT). For exclusion of loosening of the prosthesis more advanced techniques, such as single photon emission CT (SPECT/CT) are applied. In addition to classification of periprosthetic acetabular fractures by the traditional system of Letournel there are several other classification systems, which take into account the etiology of the fracture and the stability of the prosthesis...

AIMS: The best time for definitive orthopaedic care is often unclear in patients with multiple injuries. The objective of this study was make a prospective assessment of the safety of our early appropriate care (EAC) strategy and to evaluate the potential benefit of additional laboratory data to determine readiness for surgery. PATIENTS AND METHODS: A cohort of 335 patients with fractures of the pelvis, acetabulum, femur, or spine were included. Patients underwent definitive fixation within 36 hours if one of the following three parameters were met: lactate < 4...

REVIEW
José Batista Volpon
The femoroacetabular impingement (FAI) is as condition recently characterized that results from the abnormal anatomic and functional relation between the proximal femur and the acetabular border, associated with repetitive movements, which lead labrum and acetabular cartilage injuries. Such alterations result from anatomical variations such as acetabular retroversion or decrease of the femoroacetabular offset. In addition, FAI may result from acquired conditions as malunited femoral neck fractures, or retroverted acetabulum after pelvic osteotomies...

There is a mean incidence of osteoarthritis (OA) of the hip in 8% of the overall population. In the presence of focal chondral defects, defined as localized damage to the articular cartilage, there is an increased risk of symptomatic progression toward OA. This relationship between chondral defects and subsequent development of OA has led to substantial efforts to develop effective procedures for surgical cartilage repair. This study examined the effects of chondral defects and labral delamination on cartilage mechanics in the dysplastic hip during the gait cycle using subject-specific finite element analysis...

The physiopathology of the femoral head bone necrosis is similar for children and for adults. The disease is characterized by apoptosis of bone cells - bone marrow and bone forming cells-resulting in head collapse with a subsequent lesion of the overlying cartilage, and therefore flattening of the rounded surface shape of the head articulating with the acetabulum, provoking, eventually, secondary osteoarthritis. When the disease becomes clinically evident already destructive phenomena have occurred and collapse will eventually ensue...

REVIEW
George Hartofilakidis, Kalliopi Lampropoulou-Adamidou
Orthopaedic surgeons specialising in adult hip reconstruction surgery often face the problem of osteoarthritis secondary to congenital hip disease (CHD). To achieve better communication among physicians, better treatment planning and evaluation of the results of various treatment options, an agreed terminology is needed to describe the entire pathology. Furthermore, a generally accepted classification of the deformities is necessary. Herein, the authors propose the use of the term "congenital hip disease" and its classification as dysplasia, low dislocation and high dislocation...

The ilioinguinal approach is one of the standard approaches in the treatment of displaced acetabular fractures used during the last decades (9). The meta-analysis of Giannoudis et al. showed that 21.9% of acetabular fractures were historically treated using this approach (3). One of the disadvantages of this study was, that studies focussing especially on posterior wall stabilization and studies dealing with more complex fracture types treated by extended approaches were integrated. Thus, these fracture types were overrepresented...

BACKGROUND: Three-dimensional (3D) acetabular orientation is a fundamental topic in orthopedic surgery. Computed tomography (CT) allows 3D measurement of native acetabular orientation, but with a substantial radiation dose. The EOS imaging system was developed to perform this kind of evaluation, but has not been validated in this indication with specific attention to the acetabulum. We therefore performed a prospective study using EOS to assess: 1) the reproducibility of the 3D acetabulum orientation measures; 2) normative asymptomatic acetabular morphology in standing position, according to side and gender; and 3) the relationship between acetabular anteversion and pelvic incidence...

BACKGROUND Although periprosthetic fractures of the femur are a recognized complication of total hip arthroplasty, periprosthetic fractures of the acetabulum are rare. Simultaneous periprosthetic fractures of both the acetabulum and the femur have not been reported, to our knowledge. CASE REPORT We report a simultaneous fracture of the acetabulum and the femur in a 68-year-old female patient who had previously sustained a subcapital fracture of the femur, treated with a bipolar uncemented prosthesis. We discuss the possible mechanism of this combination of fractures...

Direct anterior approach to the hip allows perfect exposure of the acetabulum and an easy proximal and medial extension that makes it eligible for isolate acetabular cup revision although it is seldom used and there are only few published studies. On 23 consecutive acetabular revision (16 cases Paprosky grade 1 or 2, 5 cases 3A, 1 case 3B and 1 case 4) at an average 28-month follow up, we did not record failures or major complications. Early complications included prolonged wound healing in 4 cases and transient femoral cutaneous nerve palsy in 2 cases, the mean postoperative Harris Hip Score was 82...
