BackgroundFemoroacetabular impingement syndrome is an important cause of hip pain in young adults. It can be treated by arthroscopic surgery, including reshaping the hip, or with physiotherapist-led conservative care. We aimed to compare clinical effectiveness arthroscopy best care.MethodsUK FASHIoN a pragmatic, multicentre, assessor-blinded randomised controlled trial, done at 23 National Health Service hospitals UK. enrolled patients femoroacetabular who presented these hospitals. Eligible...
The rotational alignment of the tibia is an unresolved issue in knee replacement. A poor functional outcome may be due to malrotation tibial component. Our aim was find a reliable method for positioning component CT scans 19 knees were reconstructed three dimensions and orientated vertically. An axial plane identified 20 mm below spines. centre each condyle calculated from ten points taken round condylar cortex. tubercle also generated as circle which best fitted eight on outside at level...
This study examined the relationship between cross-over sign and true three-dimensional anatomical version of acetabulum. We also investigated whether in retroversion there is excessive femoral head cover anteriorly. Radiographs 64 hips patients being for symptoms femoro-acetabular impingement were analysed presence a was documented. CT scans same to determine relation anterior pelvic plane after correcting tilt. The sensitivity specificity 92% 55%, respectively identifying acetabular...
We present a new CT-based method which measures cover of the femoral head in both normal and dysplastic hips allows assessment acetabular inclination anteversion. A clear topographical image with its covered area is generated. studied 36 39 hips. In mean was 73% (66% to 81%), whereas group it 51% (38% 64%). The significant advantage this technique that measurements be standardised reference specific anatomical plane. When applied assessing surgery for dysplasia hip gives clearer...
In the natural and prosthetic knees position, shape, orientation of trochlea groove are three key determinants function dysfunction, yet rules governing these features remain elusive.The aim was to define three-dimensional geometry femoral its relation tibiofemoral joint in terms angles distances.Forty CT scans femurs healthy patients were analyzed using custom-designed imaging software. After aligning femur various axes, locations orientations trochlear axis examined conventional axes...
The orientation of the pelvis influences that acetabulum. In particular, pelvic tilt in sagittal plane may lead to inaccurate interpretation plain radiographs. We therefore quantified relationship between this and acetabular native hips, determined whether affects femoral head cover. analysed computed tomography scans 93 hips (36 normal, 31 dysplastic, 26 with retroversion) measured anteversion, inclination, cover at angles ranging from -20° 20° relation anterior using 5° increments. Pelvic...
Stress fractures occurring in the pubis and ischium after peri-acetabular osteotomy (PAO) are not well recognised, with a reported incidence of 2% to 3%. The purpose this study was analyse stress fracture Bernese PAO under care two high-volume surgeons. included 359 patients (48 men, 311 women) operated on at mean age 31.1 years (15 56), follow-up 26 months (6 64). Complete radiographs were available for 348 patients, 64 whom (18.4%) developed inferior pubic ramus, which noted 9.1 weeks (5...
Background: Resurfacing arthroplasty for cam-type deformities, which are a common cause of early osteoarthritis, is technically demanding operation. Like any other arthroplasty, it requires both accuracy and precision. On the basis results series reported by expert surgeons, we considered desirable that this operation should be performed within ±10° desired angular orientation ±6 mm entry-point translation in 95% hips. Technological aids now available to help surgeons achieve level accuracy....
Acetabular orientation is a crucial part of the planning and performance hip arthroplasty. Currently, most surgeons use anterior pelvic plane (APP) to orient themselves when navigating acetabulum, despite fact that superior iliac spine (ASIS) unaffected side not accessible in lateral position. We have identified another plane, transverse (TPP), relying on both posterior spines ASIS affected side. In CT-based study, this was found be as reliable APP for cup anteversion inclination. The...
CT when compared to plain radiograph is known be a more valid measure of acetabular component orientation. The validity radiographs may further compromised by large diameter metal femoral heads because obscuration the rim. We quantified this effect measuring cup angles (inclination and version) 49 on (MOM) hip resurfacings using 3D based measurement. Bland-Altman plots revealed poor agreement between radiographic measurement with 2 standard deviation limits agreements of: +7 –15 degrees for...
Acetabular center positioning has an effect on hip function. However, reported clinical and plain radiographic methods are inaccurate unreliable for ascertaining acetabular implant location. In exploratory study we asked whether the normal position can be derived from simple radiographically measurable pelvic dimensions. We analyzed computed tomographic scans of 37 hips using a frame reference centered ipsilateral anterior-superior iliac spine. defined x-, y-, z-coordinates (C(x),C(y),C(z))...
The aim of this study is to establish whether management patients in a unit dedicated the treatment hip fractures improves acute outcomes. We prospectively studied 300 with two separate groups. Patients Group 1 were operated on mixed trauma and recovered traditional ward. 2 theatres which catered exclusively for fractures. ages, ASA grades, type procedure performed groups comparable. 30-day mortality rate was 9% as opposed 12% (P = 0.34). inpatient length stay significantly lower (18 days...
Coxa saltans occurring at the proximal hamstring origin has been rarely reported in literature. It is better known as iliotibial band or iliopsoas tendon. We report a case of coxa due to subluxation long head biceps femoris tendon ischial tuberosity. This was successfully treated using mini-open surgical technique. Six weeks postoperatively, snapping and associated pain were abolished patient able resume their participation athletic activities.
