Filter by:There are numerous ways to measure limb length discrepancy in the clinical practice, although their reliability and accuracy are not well known. In our prospective diagnostic study we aimed to test the most popular methods and compare their results to EOS 3D reconstructions data.
This study is designed as a randomized, placebo-controlled, double-blinded, clinical trial with two parallel groups. This study investigates the association between a single dose of the drug, Clonidine, and the total amount of opioid administered under and 24 hours after surgery in children undergoing orthopedic limb surgery with the use of tourniquet. The investigators hypothesize that administration of clonidine to children undergoing limb surgery with the use of inflatable tourniquets would reduce post-procedural pain. This study is a pilot to obtain an effect size. Based on this the investigators will calculate a sample size for the main trial enabling us to reach a power of 0.8 with a significans level of 0.05.
This research will assess whether vibration therapy can increase bone-growth in length of the shorter leg in children aged 6-12 years with pre-existing leg length difference (LLD) which is being treated with a heel-raise or orthotics. Children will be referred by orthopaedic and musculoskeletal clinics, physiotherapists and orthotists. Children will have monthly measurement of leg length (LL) over a 13 month period (4 months pre-treatment, 3 months treatment, 6 months post-treatment) using a portable Ultrasound-laser system which is safe, accurate, reproducible and validated against standing x-ray measurement. During the treatment phase they will be randomised to receive vibration therapy 3 times per week using a vibration platform at 30 Hz and very low amplitude of 0.4g (less than experienced when walking) or 30 Hz at 1.0 g (the same force as standing with the effect of gravity). The child will stand with the shorter leg on the platform and the longer leg on a stationary block for 15 minutes per treatment session. The aim is to assess the potential of this safe, non-invasive and potentially cost-effective method for levelling LL. If effective, the research could be extended in future to children with much larger LLD in whom it could potentially avoid the need for surgery and minimise long-term musculoskeletal disability.
This is a randomized clinical trial of epiphysiodesis techniques: percutaneous transphyseal screw epiphysiodesis versus percutaneous drill epiphysiodesis for the correction of leg length discrepancy. Failed epiphysiodesis was selected as the primary outcome. Failed epiphysiodesis was defined as one or more of the following: development of angular deformity > 5°, revision epiphysiodesis, or growth inhibition < 70% of expected. EOS, low dose biplanar X-Ray, will be used to make all length measurements. Secondary outcomes assess mean growth at the physis following epiphysiodesis, in the subset of patients with bead implantation, fluoroscopy and operative times, length of stay, return to full weight bearing, as well as functional and quality of life outcomes. The following outcome scales will be used to measure pain (VAS), quality of life (PROMIS Pediatric Pain Interference Scale), and function (PROMIS Pediatric Mobility Scale, Pedi-FABS, and UCLA Activity Score). Each of these scales has been validated for use in children (Beyer, Denyes, & Villarruel, 1992; DeWitt et al., 2011; Fabricant et al., 2013; Novais et al., 2014; Varni et al., 2010a). We will also determine the cost associated with each technique and perform a cost-effectiveness analysis to establish which technique is preferred from a societal perspective.
Leg length discrepancies following total hip arthroplasty have been associated with nerve palsies, gait abnormalities, and lower back pain. Leg length discrepancies are related to poorer functional outcomes and patient dissatisfaction. Failure to restore femoral offset following total hip arthroplasty has been linked to decreased range of motion and abductor muscle strength, impingement, limping, higher dislocation rates, increased polyethylene wear, and loosening of implants. Computer navigation has shown to improve the accuracy of leg length and hip offset during total hip arthroplasty. The investigators research objective is to prove the accuracy of the Intellijoint HIP™ system for determining leg length and hip offset. The investigators hypothesis was that Intellijoint HIP™, an imageless intraoperative intelligent instrument, could improve the accuracy of leg length and hip offset during primary total hip arthroplasty. The investigators plan to study this hypothesis in humans by comparing the leg length and hip offset discrepancies produced with Intellijoint HIP™ to the standard at the investigators institution, which is a pin and outrigger system.
BACKGROUND: Distraction osteogenesis, the gradual lengthening of bones, is performed in order to equalize leg length discrepancy and correct skeletal deformities or to achieve greater height in short stature people. The femur and tibia are the bones most frequently lengthened. The surgery is currently performed at Hadassah Medical Center routinely by the pediatric orthopedic team utilizing a variety of external fixation devices. The procedure involves application of an external fixation device to the bone, creation of an osteotomy and gradual, controlled distraction of the bone fragments On the last week of the distraction phase and every month thereafter, patients will be provided with a monthly supply of gastrolith calcium in a sealed container (65 capsules of 500 mg each, provided by Amorphical). Starting on the first day of the last week of the distraction phase, during the entire consolidation phase until the external fixator is removed; adults will orally consume two (2) 500 mg capsules a day (total of 1 gr of gastrolith calcium). Children will be given 25 mg calcium per kg body weight up to the daily adult dose of 1000mg .
