Background We previously reported the 5-year followup of hips with femoroacetabular impingement (FAI) that underwent surgical hip dislocation trimming head-neck junction and/or acetabulum including reattachment labrum. The goal this study was to report a concise these patients at minimum 10 years. Questions/purposes asked if had (1) improved pain and function; we then determined (2) 10-year survival rate (3) calculated factors predicting failure. Methods Between July 2001 March 2003,...
Background Acetabular retroversion can cause impaction-type femoroacetabular impingement leading to hip pain and osteoarthritis. It be treated by anteverting periacetabular osteotomy (PAO) or acetabular rim trimming with refixation of the labrum. There is increasing evidence that a rotational abnormality entire hemipelvis not focal overgrowth anterior wall, which favors an PAO. However, it unknown if this larger procedure would beneficial in terms survivorship Merle d'Aubigné scores midterm...
Magnetic resonance arthrogram (MRA) with radial cuts is presently the best available preoperative imaging study to evaluate chondrolabral lesions in setting of femoroacetabular impingement (FAI). Existing followup studies for surgical treatment FAI have evaluated predictors failure based on clinical examination, intraoperative findings, and conventional radiography. However, our knowledge, no has examined whether any findings MRA images might be associated long term.The purposes this were...
Severe femoral head deformities in the frontal plane such as hips with Legg-Calvé-Perthes disease (LCPD) are not contained by acetabulum and result hinged abduction impingement. These rare cannot be addressed resection, which would endanger vascularity. Femoral reduction osteotomy allows for reshaping of goal improving sphericity, containment, hip function.Among severe asphericity head, does (1) improved sphericity containment; (2) pain relief function; (3) subsequent reoperations or...
Background: Cam morphology in association with femoroacetabular impingement (FAI) is a recognized cause of hip pain and cartilage damage proposed as leading arthritis. The purpose this study was to analyze the functional biomechanical effects surgical correction cam deformity on degenerative process associated FAI. Methods: Ten male patients mean age 34.3 years (range, 23.1 46.5 years) body mass index (and standard deviation) 26.66 ± 4.79 kg/m 2 underwent corrective surgery for Each patient...
Background/Objectives: Older trauma patients experience increased in-hospital mortality due to the physiological challenges associated with aging and injury severity. However, limited data exist on long-term rates beyond hospital discharge, particularly among severely injured elderly patients. Understanding these outcomes is essential for improving clinical management rehabilitation strategies. The objective of this study was evaluate cumulative (in-hospital, 28-day, 1-year, 2-year, 3-year)...
Background Since the importance of an intact labrum for normal hip function has been shown, labral reattachment become standard method open or arthroscopic treatment hips with femoroacetabular impingement (FAI). However, no long-term clinical results exist evaluating effect reattachment. A 2-year followup comparing surgical FAI resection versus was previously performed at our clinic. The goal this study to report a concise these patients minimum 10 years. Questions/purposes We asked if...
Arthroscopic treatment of symptomatic femoroacetabular impingement (FAI) has promising short-term to mid-term results. In addition treating acute pain or impaired function, the goal hip-preserving surgery is achieve a lasting improvement hip function and prevent development osteoarthritis. Long-term results are necessary evaluate effectiveness surgical further improve by identifying factors associated with conversion THA.(1) How do Merle d'Aubigné-Postel scores change from before follow-up...
Background: There is controversy whether nonoperative or operative treatment for Achilles tendon rupture superior. It unknown if patients with acute return to previous sports activity. The purpose of this study was assess 5-year sport and subjective satisfaction, minimum 1-year functional outcomes, complications in following early weightbearing rehabilitation. Methods: An institutional review board–approved, retrospective observational involving 89 performed. Out 114 consecutive patients,...
T1ρ MRI has been shown feasible to detect the biochemical status of hip cartilage, but various region-of-interest strategies have used, compromising reproducibility and comparability between different institutions studies.The purposes this study were (1) determine representative regions interest (ROIs) for cartilage mapping in hips with a cam deformity; (2) assess intra- interobserver reliability deformity.The local ethics committee approved prospective written informed consent obtained....
Hips with a cam deformity are at risk for early cartilage degeneration, mainly in the anterolateral region of joint. T1ρ MRI is described technique assessment proteoglycan content hyaline and subsequently damage. In this study, 1.5 Tesla was performed on 20 asymptomatic hips compared to 16 healthy control hips. Cam defined as an alpha angle 1:30 o'clock position over 60° and/or 3:00 50.5°. Hip segmented divided into four regions interest (ROIs): anterolateral, anteromedial, posterolateral,...
INTRODUCTION: The COVID-19 pandemic and the associated restrictions may have modified activities of Swiss population thus altered trauma patterns. MATERIALS AND PATIENTS: All adult patients with major admitted to our institution in 2019 2020 were assessed using Injury Severity Score (ISS), by body region involved, type injury, age, admission an intensive care unit 30-day mortality. RESULTS: In 2020, 454 institution, 17% fewer than previous year. drop number proceeded overlapped both first...
Compression sonography has been introduced for non-invasive measurement of compartment compressibility and possible diagnostic tool acute or chronic syndrome in studies using human cadavers animal models. To date, standard values healthy subjects are not yet defined. The aim was to define assess the reliability this method.In 60 volunteers, ultrasound, diameter tibial anterior measured while applying no pressure, 10mbar 80mbar external pressure. A pressure manometer on ultrasound head used...
In the present study, we aimed to identify risk factors for failure (defined as reoperation within 60 days) after debridement or amputation at lower extremity in patients with diabetic foot syndrome and develop a model using significant predict success rate different levels of amputation.Between September 2012 November 2016, performed prospective observational cohort study 174 surgeries 105 syndrome. all patients, level amputation, need reoperation, time potential were assessed. A cox...
The etiology of hallux rigidus remains a controversial issue in foot and ankle surgery, i.e., the relationship between metatarsus primus elevatus (MPE) rigidus. purpose this study was to evaluate several radiographic parameters including first metatarsal elevation patients with compared matched control group. A retrospective case performed 50 feet, 25 feet without In rigidus, more elevated than group (8.3 ± 1.7 mm vs 3.0 2.0 mm, p < .001) 60% MPE diagnosed, zero (p .001). lateral 1 2...
Objectives Hips with metal-on-metal total hip arthroplasty (MoM THA) have a high rate of adverse local tissue reactions (ALTR), often associated hypersensitivity reactions. Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) measures perfusion the parameter Ktrans (volume transfer constant contrast agent). Our purpose was 1) to evaluate feasibility DCE-MRI in patients THA and 2) compare MoM bearings metal-on-polyethylene (MoP) bearings, hypothesising that index hips is higher than...
