Arthroscopic surgery of the hip, compared to that of the knee or the shoulder, has only recently been developed in any significant way. Current indications for arthroscopic surgery of the hip include: diagnosis and treatment of lesions symptomatic of the acetabular labrum, femoroacetabular impingement (FAI), chondral lesions, joint infections, lesions of the teres ligament, impingement of the psoas tendon, pathology of the peritrochanteric space, external snapping hip (coxa saltans), and traumatic and atraumatic instability...

BACKGROUND: Determining an accurate clinical diagnosis for nonarthritic hip pain may be challenging, as symptoms related to femoroacetabular impingement (FAI) or hip instability can be difficult to elucidate with current testing methods. In addition, commonly utilized physical examination maneuvers are static and do not include a dynamic or weightbearing assessment to reproduce activity-related symptoms. Therefore, implementing a dynamic assessment for FAI and hip instability could help to improve diagnostic accuracy for routine clinical examinations of patients with nonarthritic hip pain...

BACKGROUND: The modified Dunn procedure has the potential to restore the anatomy in hips with slipped capital femoral epiphyses (SCFE) while protecting the blood supply to the femoral head and minimizing secondary impingement deformities. However, there is controversy about the risks associated with the procedure and mid- to long-term data on clinical outcomes, reoperations, and complications are sparse. QUESTIONS/PURPOSES: Among patients treated with a modified Dunn procedure for SCFE, we report on (1) hip pain and function as measured by the Merle d'Aubigné and Postel score, Drehmann sign, anterior impingement test, limp, and ROM; (2) the cumulative survivorship at minimum 10-year followup with endpoints of osteoarthritis (OA) progression (at least one Tönnis grade), subsequent THA, or a Merle d'Aubigné and Postel score < 15; (3) radiographic anatomy of the proximal femur measured by slip angle, α angle, Klein line, and sphericity index; and (4) the risk of subsequent surgery and complications...

INTRODUCTION: Periacetabular osteotomy (PAO) is an effective joint-preserving procedure for young adults with developmental dysplasia of the hip. Although PAO provides excellent radiographic and clinical results, it is a technically demanding procedure with a distinct learning curve that requires careful 3D planning and, above all, has a number of potential complications. We therefore developed a pre-operative simulation method for PAO via creation of a new full-scale model. METHODS: The model was prepared from the patient's Digital Imaging and Communications in Medicine (DICOM) formatted data from computed tomography (CT), for construction and assembly using 3D printing technology...

INTRODUCTION: Surgical hip dislocation (SHD) in the therapy of femoral acetabular impingement (FAI) has been mostly replaced by minimally invasive techniques. Nevertheless, in the circumstances of complex FAI types and combined impingement located in inaccessible areas of the hip, SHD is an option to reach those deformities. The advantage of the complete overview of the hip joint enables the circumferential therapy of bony deformity, but at the expense of higher invasivity. In the literature there is still a lack of mid to long-term studies of SHD to determine the overall treatment outcome...

BACKGROUND: Most surgeons advocate in situ fixation of the slipped epiphysis with acceptance of any persistent deformity in the proximal femur [Aronsson DD, Loder RT, Breur GJ, Weinstein SL (2006) Slipped capital femoral epiphysis: current concepts. J Am Acad Orthop Surg 14, 666-679]. This residual deformity can lead to osteoarthritis due to femoroacetabular cam impingement (FAI) [Leunig M, Slongo T, Ganz R (2008) Subcapital realignment in slipped capital femoral epiphysis: surgical hip dislocation and trimming of the stable trochanter to protect the perfusion of the epiphysis...

BACKGROUND: Hypertrophic labrum in dysplastic hip has been frequently reported and is known as limbus in developmental dysplasia of the hip. However, hypertrophic labrum without hip dysplasia has not been reported to date. The purpose of this study was to define hypertrophic labrum and to investigate the prevalence and clinical significance of an abnormally hypertrophic labrum in non-dysplastic hips. METHODS: Between 2007 and 2014, direct CT arthrography was performed in 464 patients (470 hips) who had chronic groin pain and positive impingement or Faber test...

BACKGROUND: Dual mobility cup (DMC) inserts reduce the risk of dislocation after total hip arthroplasty (THA). No available research has clearly delineated stability advantages of DMC inserts in primary and revision THA. We investigated: (i) the degree of change in the safe zone of the cup when a DMC insert is used compared to a fixed insert; (ii) the method of selecting candidates for a DMC insert without changing the position of the acetabular (cup) component during revision THA in frequent dislocation cases caused by implant impingement...

Slipped capital femoral epiphysis (SFCE) is a disorder of the hip, characterized by a displacement of the capital femoral epiphysis from the metaphysic through the femoral growth plate. The epiphysis slips posteriorly and inferiorly. SCFE occurs during puberty and metabolic and epidemiologic risk factors, such as obesity are frequently found. Most chronic slips are diagnosed late. Sagittal hip X-rays show epiphysis slip. In case of untreated SCFE, a slip progression arises with an acute slip risk. Treatment is indicated to prevent slip worsening...

Every hip is unique. The area of cam impingement is more proximal in patients with borderline developmental dysplasia of the hip. It is important to recognize this to ensure successful treatment.

Patients with anterior cruciate ligament (ACL) injury had significantly less hip rotational motion (internal rotation [IR] and sum of IR and external rotation) than control subjects without ACL tears. For each hip IR increase of 10°, the odds of sustaining an ACL rupture decreased by a factor of 0.419. Although this investigation does not prove (causation) that loss of hip rotational motion causes an ACL tear, it does continue to complement the growing and evolving literature base showing an upstream or downstream association (correlation) of decreased hip motion on adjacent structures...

BACKGROUND: Pelvic posture and kinematics influence acetabular orientation and are therefore expected to be involved in the pathomechanics of femoroacetabular impingement (FAI). This systematic review aims to determine whether FAI patients show pelvic postures or patterns of motion contributing to impingement or, conversely, develop compensatory postures and patterns of motion preventing it. MATERIALS AND METHODS: PubMed/MEDLINE, Embase, Google Scholar and the Cochrane Library were systematically searched to find all the studies that measured pelvic positional and/or kinematic data in humans (patients or cadaveric specimens) affected by FAI...

The iliopsoas tendon is an important dynamic stabilizer of the hip joint, and it should be carefully identified and preserved during routine hip arthroscopy. However, it may also be a source of hip pain manifesting as iliopsoas tendinitis or a snapping hip or contributing to the development of labral pathology caused by psoas impingement. In the appropriately indicated, refractory cases of iliopsoas-related hip pain, surgical intervention in the form of an iliopsoas tenotomy at the level of the labrum can result in reliable pain relief...

Arthroscopic procedures for treatment of hip pathology are growing exponentially as a result of continued improvements in the understanding of intra- and extra-articular hip anatomy and technological advancements in instrumentation. Nevertheless, it has been reported that the main cause of revision hip arthroscopy is related to a suboptimal intrasurgical management of the abnormal morphology in femoroacetabular impingement (FAI). Under-resection, over-resection, and in some cases combined under-resection and over-resection at different locations of the cam lesion at the femoral head-neck junction may lead to poor outcomes as a result of residual impingement or the iatrogenic creation of structural instability...

Minimally invasive percutaneous radiofrequency ablation (RFA) techniques are the standard of care for treating simple osteoid osteomas (OOs). Historically, OOs were treated with open en bloc resection or curettage of the nidus. RFA procedures have been linked to soft-tissue complications of varying severity. In addition, RFA may be a poor choice for periarticular OOs because of the potential for procedure-related articular cartilage damage. Hip arthroscopy is a widely accepted approach for the treatment of femoroacetabular impingement...

Femoroacetabular impingement (FAI) is an increasingly recognized cause of hip pain. This pathology often involves abnormal femoral neck shape (cam-type FAI), acetabular over coverage (pincer-type FAI), or mixed pathology. Surgical treatment of this entity includes labral repair and femoral head-neck osteochondroplasty. A mindful arthroscopic technique is of paramount importance, because maintaining the integrity of the labrum and a corresponding neck volume has been reported to be vital in maintaining the hip suction seal...

Synopsis Although osteoarthritis (OA) has traditionally been considered a disease of older age, hip and knee OA can and does affect younger adults, with a profound impact on psychosocial well-being and work capacity. Obesity and a history of traumatic knee injury (eg, anterior cruciate ligament rupture and/or meniscal tear) are key risk factors for the accelerated development of knee OA, while structural hip deformities (including those contributing to femoroacetabular impingement syndrome) are strong predictors of early-onset hip OA...

BACKGROUND: Generalized joint hypermobility (JH) might negatively influence the results of surgical femoroacetabular impingement (FAI) treatment, as JH has been linked to musculoskeletal pain and injury incidence in athletes. JH may also be associated with worse outcomes of FAI surgery in thin females. PURPOSE: To (1) determine the results of FAI surgery at a minimum 2-year follow-up by means of patient-reported outcome measures (PROMs) and failure rates, (2) assess the prevalence of JH in FAI patients and its effect on outcomes, and (3) identify other risk factors associated with treatment failure...
