Valgus hips with increased antetorsion present lack of external rotation and posterior hip pain that is aggravated extension rotation. This may be the result femoroacetabular impingement (FAI).
Background In recent years, surgical treatment of symptomatic femoroacetabular impingement (FAI) has been increasingly performed using arthroscopy. Bony pathomorphologies and damage to the labrum as well cartilage defects can be addressed with comparable results open surgery overall less surgery-related complications. Despite increasing importance hip arthroscopy, however, reports on midterm clinical radiographic outcomes comparison dislocation are scarce. Questions/purposes (1) What at a...
The iliocapsularis muscle is an anterior hip structure that appears to function as a stabilizer in normal hips. Previous studies have shown the hypertrophied developmental dysplasia of (DDH). An easy MR-based measurement ratio size adjacent anatomical structures such rectus femoris might be helpful everyday clinical use.We asked (1) whether iliocapsularis-to-rectus-femoris for cross-sectional area, thickness, width, and circumference increased DDH when compared with hips acetabular...
In some hips with cam-type femoroacetabular impingement (FAI), we observed a morphology resembling more subtle form of slipped capital femoral epiphysis (SCFE). Theoretically, the in these should differ from primary deformity.We asked if (1) head-neck offset; (2) epiphyseal angle; and (3) tilt angle among slip-like morphology, idiopathic cam, after situ pinning SCFE, normal hips; (4) what is prevalence hips?We retrospectively compared three-dimensional anatomy (29 hips), for SCFE (eight cam...
Delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) allows an objective, noninvasive, and longitudinal quantification biochemical properties. Although dGEMRIC has been used to monitor the course degeneration after periacetabular osteotomy (PAO) for correction hip dysplasia, such data are currently lacking femoroacetabular impingement (FAI).(1) How does mean acetabular femoral index change surgery FAI at 1-year followup compared with a similar group patients treated without surgery? (2)...
Introduction: The RM Pressfit vitamys is an uncemented, titanium particle-coated, isoelastic monoblock cup made of vitamin E blended highly cross-linked polyethylene. We addressed the following questions: (1) What are clinical and (2) radiographic outcomes 10 years after implantation? (3) revision rate? Methods: In this prospective observational study in a tertiary care centre we investigated all consecutive cases total hip replacement with between September 2009 November 2011. It was...
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...
The current treatment of painful hip dysplasia in the mature skeleton is based on acetabular reorientation. Reorientation procedures attempt to optimize anatomic position hyaline cartilage femoral head and acetabulum regard mechanical loading. Because Bernese periacetabular osteotomy a versatile technique for reorientation, it helpful understand approach be familiar with criteria an optimal surgical correction. side bears stigmata that may require Improvement head-neck offset avoid...
Background: Delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC) allows objective and noninvasive assessment quality. An interim analysis 1 year after correction femoroacetabular impingement (FAI) previously showed that the dGEMRIC index decreased despite good clinical outcome. Purpose: To evaluate indices longitudinally in patients who underwent FAI a control group undergoing nonoperative treatment for FAI. Study Design: Cohort study; Level evidence, 3. Methods:...
Ultrasonography is a fast and patient-friendly modality to assess cartilage thickness. However, inconsistent results regarding accuracy have been reported. Therefore, we asked what are (1) the accuracy, (2) reproducibility, (3) reliability of ultrasonographic thickness measurement using contrast-enhanced micro-CT for validation? A series 50 cartilage–bone plugs were harvested from fresh bovine porcine joints. Ultrasonic was determined an A-mode, 20-MHz hand-held ultrasonic probe with native...
: Intramedullary nailing of trochanteric fractures can be challenging and sometimes the clinical situation does not allow perfect implant positioning. The aim this study was (1) to compare in human cadaveric femoral heads biomechanical competence two recently launched cephalic implants inserted either an ideal (centre-centre) or less-ideal anterior off-centre position, (2) investigate effect bone cement augmentation on their fixation strength position.
The aims of this study were to determine the cumulative ten-year survivorship hips treated for acetabular fractures using surgical hip dislocation and identify factors predictive an unfavourable outcome.We followed up 60 consecutive patients (61 hips; mean age 36.3 years, standard deviation (sd) 15) who underwent open reduction internal fixation a displaced fracture acetabulum (24 posterior wall, 18 transverse ten transverse, nine others) with follow-up 12.4 years (sd 3).Clinical grading was...
Anterior femoroacetabular impingement (FAI) is associated with labral tears and acetabular cartilage damage in athletic young patients. Delayed gadolinium-enhanced magnetic resonance imaging of (dGEMRIC) an method for detecting early to cartilage.We evaluated the following questions: (1) What sensitivity specificity morphological (MRI) dGEMRIC damage? Do mean femoral indices differ between (2) superior clock positions without (3) cam- pincer-type FAI?Cohort study (diagnosis); Level evidence,...
Introduction: The best treatment of acetabular chondral flaps during surgery for femoroacetabular impingement (FAI) is unknown. We asked if subchondral drilling improves clinical and radiographic outcome there are factors predicting failure. Methods: treated 79 patients with symptomatic FAI surgical hip dislocation between January 2000 December 2007. Exclusion all previous pathology or trauma resulted in 62 (80 hips). flap was slightly debrided 43 patients/51 hips (control group). In 28...
