PURPOSE: The purpose of this study is to report the clinical course of fatigue-type subchondral fractures of the femoral head in young healthy adults. MATERIALS/METHODS: We retrospectively reviewed 28 consecutive patients (34 hips) who had a clear history of a sudden increase in physical activity without trauma on the hip and pelvis, and were diagnosed as having a fatigue-type subchondral fracture of the femoral head. The diagnosis was made primarily on the basis of sequential plain radiographs and magnetic resonance images...

PURPOSE: In revision total hip arthroplasty, until today, orthopaedic surgeons are missing evidence-based guidelines on cementless acetabular cup fixation. METHODS: 5 finite element models were generated featuring the following anchorage strategies: 1 short peg, 1 long peg, 2 long screws, 3 short screws and zero anchoring components for reference. The micromotions at the implant-bone interface were analyzed for 3 different loadcases, "Seated leg-crossing" (joint force 940 N, impingement force 750 N), "Normal gait" (joint force 1820 N), and "Stumbling" (joint force 4520 N)...

Hip preservation surgery encompasses various surgical procedures that have the goal of decreasing the progression of osteoarthritis, preserving normal hip function, and delaying the need for arthroplasty. These procedures can encompass arthroscopic, open, and combined techniques. This study investigated the trends and complications associated with open hip preservation surgery performed by candidates undergoing Part II of the American Board of Orthopaedic Surgery examination. The American Board of Orthopaedic Surgery Part II surgeon case database was queried from the years 2003 to 2013 for Current Procedural Terminology (CPT) codes related to open hip preservation surgery in patients 10 years and older...

BACKGROUND: Hip dysplasia represents a spectrum of complex deformities on both sides of the joint. Although many studies have described the acetabular side of the deformity, to our knowledge, little is known about the three-dimensional (3-D) head and neck offset differences of the femora of dysplastic hips. A thorough knowledge of proximal femoral anatomy is important to prevent potential impingement and improve results after acetabular reorientation. QUESTIONS/PURPOSES: (1) Are there common proximal femoral characteristics in patients with symptomatic hip dysplasia undergoing periacetabular osteotomy (PAO)? (2) Where is the location of maximal femoral head and neck offset deformity in hip dysplasia? (3) Do certain subgroups of dysplastic hips more commonly have cam-type femoral morphology? (4) Is there a relationship between hip ROM as well as impingement testing and 3-D head and neck offset deformity? METHODS: Using our hip preservation database, 153 hips (148 patients) underwent PAO from October 2013 to July 2015...

BACKGROUND: Among the chronic rheumatic diseases, hip and knee osteoarthritis (OA) is the most prevalent and is a leading cause of pain and disability in most countries worldwide. Its prevalence increases with age and generally affects women more frequently than men. OA is strongly associated with aging and heavy physical occupational activity, a required livelihood for many people living in rural communities in developing countries. Determining region-specific OA prevalence and risk factor profiles will provide important information for planning future cost effective preventive strategies and health care services...

BACKGROUND: Since the importance of an intact labrum for normal hip function has been shown, labral reattachment has become the standard method for open or arthroscopic treatment of hips with femoroacetabular impingement (FAI). However, no long-term clinical results exist evaluating the effect of labral reattachment. A 2-year followup comparing open surgical treatment of FAI with labral resection versus reattachment was previously performed at our clinic. The goal of this study was to report a concise followup of these patients at a minimum of 10 years...

BACKGROUND: Complex groin defects after sarcoma resection require reconstruction of multiple vital structures that can include the major vessels, the overlying skin, the abdominal wall, and the hip joint. We investigated the feasibility of limb preservation after complex groin reconstruction. METHODS: The subjects were 12 consecutive patients who underwent complex groin reconstruction after sarcoma resection. In all patients, the defect included a major artery (external iliac or femoral) and overlying skin...

Osteoarthritis of the hip remains a prevalent disease condition that influences ever-changing treatment options. Procedures performed to correct anatomic variations, and, in turn, prevent or slow the progression of osteoarthritis, are aptly referred to as types of hip preservation surgery (HPS). Conditions that predispose individuals to femoroacetabular impingement (FAI), including pincer- and cam-type morphology, and hip dysplasia are specifically targeted in HPS. Common surgical interventions include acetabuloplasty, osteochondroplasty, periacetabular osteotomy (PAO), and derotational femoral osteotomy (DFO)...

BACKGROUND: Although epicardial adipose tissue (EAT) volume is associated with increased incidence of coronary artery disease (CAD), its role in myocardial systolic dysfunction is unclear. The present study aimed to identify independent determinants of EAT volume in patients without obstructive CAD, and to evaluate the association between EAT volume (vs other measures of obesity) and myocardial systolic strain analysis. METHODS: We prospectively recruited 130 patients without obstructive CAD on contrast-enhanced cardiac computed tomography imaging and normal left ventricular ejection fraction on 3-dimensional (3D) echocardiography...

BACKGROUND: Delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) allows an objective, noninvasive, and longitudinal quantification of biochemical cartilage properties. Although dGEMRIC has been used to monitor the course of cartilage degeneration after periacetabular osteotomy (PAO) for correction of hip dysplasia, such longitudinal data are currently lacking for femoroacetabular impingement (FAI). QUESTIONS/PURPOSES: (1) How does the mean acetabular and femoral dGEMRIC index change after surgery for FAI at 1-year followup compared with a similar group of patients with FAI treated without surgery? (2) Does the regional distribution of the acetabular and femoral dGEMRIC index change for the two groups over time? (3) Is there a correlation between the baseline dGEMRIC index and the change of patient-reported outcome measures (PROMs) at 1-year followup? (4) Among those treated surgically, can dGEMRIC indices distinguish between intact and degenerated cartilage? METHODS: We performed a prospective, comparative, nonrandomized, longitudinal study...

Advanced hip joint-preserving arthroscopic techniques have been shown to improve patient-reported functional outcomes with low rates of postoperative complications. Prior work has shown that formation of adhesive scar is a potential source of persistent pain and cause for revision surgery. As resources for postoperative in-studio physical therapy become scarce, a home-based strategy to avoid scar formation without adding formal therapy cost may be beneficial. The purpose of this technical note is to introduce a patient-centered educational video technique for home-caregiver delivery of manual hip pendulum exercises in the postoperative setting...

This article describes the use of sutures to enhance visualization while protecting the capsule in both the central and peripheral compartments during hip arthroscopy. We describe first a technique to preserve the proximal capsule cuff while working in the central compartment and then an alternative to the T-capsulotomy while maintaining excellent visualization of the peripheral compartment during femoroplasty of cam-type femoroacetabular impingement. By use of suture suspension of the capsule, multiple goals are achieved: The integrity of the proximal capsule cuff is maintained while aiding in visualization of the central compartment; the iliofemoral ligament is spared, which plays a critical role in preventing microinstability; the necessary space is created to obtain adequate visualization of the peripheral compartment for complete femoroplasty; and operative time is reduced because creation and subsequent repair of the T-capsulotomy can be avoided...

BACKGROUND: Surgical treatment for pincer femoroacetabular impingement (FAI) of the hip remains controversial, between trimming the prominent acetabular rim and reverse periacetabular osteotomy (PAO) that reorients the acetabulum. However, rim trimming may decrease articular surface size to a critical threshold where increased joint contact forces lead to joint degeneration. Therefore, knowledge of how much acetabular articular cartilage is available for resection is important when evaluating between the two surgical options...
