Functional Capacity After Computer Assisted Periacetabular Osteotomy in Patients With Hip Dysplasia...
Hip DysplasiaPathogenesis of hip dysplasia Hip dysplasia is multifactorial in origin influenced by genetic and intrauterine factors, such as mechanical (rump presentation and oligohydramnios) and hormonal factors1. To ease the passage through the birth canal, the hip joint is quite mobile perinatally. Postnatally, the laxity of the ligaments will subside and the femoral head will normally position itself deeply in the acetabulum2. The theory is that if the femoral head does not migrate sufficiently into the acetabulum, dysplasia may develop because the matrice to stimulate acetabular growth is not correctly positioned. Normally, at birth the femoral head sits deep in the acetabulum held by surface tension of the synovial liquid. The growth and the hemispherical morphology of acetabulum are dependent on the presence of a normally growing and correctly placed spherical femoral head that works as a convex matrice. If for some reason the normal development is disturbed pre- or postnatally, pathologic relations may develop between the femoral head and the acetabulum3, leading to hip dysplasia. Purpose of this research project is to investigate if the correction of the acetabulum is accurately performed when the surgeon use navigation equipment during PAO.
Efficacy of Aquamantys for Reducing Transfusions With Anterior Supine Intermuscular Approach Total...
OsteoarthritisHip7 moreThe purpose of this study is to establish whether or not there is a clinical advantage to the use of Aquamantys® System from Medtronic Advanced Energy (formerly Salient Surgical Technologies) in patients undergoing primary total hip arthroplasty via the anterior supine intermuscular surgical approach in terms of blood loss, transfusion and wound healing. Wound healing will be assessed by a blinded observer and based upon a simple and subjective criteria: a) as expected, b) better than expected or c) worse than expected. The blinded observer is experienced in the care of the surgical patient and wound evaluation.

Rheumatoid ArthritisOsteoarthritis7 moreThe purpose of this study is to monitor the performance of artificial hip joints implanted with two different bone cements, SmartSet® HV and SmartSet® GHV, in the treatment of patients with hip joint disease requiring a total hip replacement. Patients who enter the study will be randomly allocated to SmartSet® HV or SmartSet® GHV and will be evaluated at regular intervals following hip surgery using patient, clinical and x-ray assessments
Treatment for Mild Hip Dysplasia in Newborns
Developmental Dysplasia of the HipDevelopmental dysplasia of the hip is the most common musculoskeletal disorder in infancy, with a reported prevalence of 2% of all newborns. Although newborn screening programs based on clinical examination with Ortolani and Barlow tests were introduced in the 1950's and 1960's with early abduction splinting of the 2% testing positive, the prevalence of late cases warranting surgery has remained stable, around one per 1000. This has led to the introduction of ultrasound as an additional diagnostic tool, resulting in treatment rates of until 5-6%. This three fold increase in abduction splinting treatment is partly due to the initiation of treatment of infants in whom mild hip dysplasia but no hip instability has been identified. The benefit of early treatment of mild dysplasia in a hip that is neither dislocated nor dislocatable is unclear. Further, abduction splinting is not without risk, with avascular necrosis being reported in around 1%. The investigators conducted a masked, randomized, controlled trial to examine whether mildly dysplastic but stable or instable hips would benefit from early treatment, as compared to watchful waiting.

A Randomized Control Trial of Hip Dislocation Techniques for Pediatric Patients With Cerebral Palsy...
Hip DysplasiaCerebral PalsyThis randomized controlled trial will compare proximal femoral resection-interposition arthroplasty to proximal femoral resection with subtrochanteric valgus osteotomy for the treatment of painful irreducible hip dislocation in patients with cerebral palsy. The primary outcome is quality of life and care giver burden measured by The Caregiver Priorities and Child Health Index of Life with Disabilities (CPCHILD) score at one year. Secondary outcomes will include pain (NCCPC-R, PROMIS pain intensity and PROMIS pain interference), function (mobility questions), complications and surgical parameters such as OR time and fluoroscopy time. A cost-effectiveness analysis will follow completion of the randomized controlled trial (RCT). The authors hypothesize that mean CPCHILD scores (measured at 1 year) will be significantly higher following the Subtrochanteric Valgus Osteotomy technique compared to Proximal Femoral Resection-Interposition Arthroplasty technique. Furthermore, the Proximal Femoral Resection-Interposition Arthroplasty technique will have a shorter length of hospital stay, shorter fluoroscopy and OR times and the Subtrochanteric Valgus Osteotomy will have longer sitting tolerance, less pain, smaller burden for caregivers, better health, and higher quality of life. Additionally the authors hypothesize that Subtrochanteric Valgus Osteotomy will be more expensive than Proximal Femoral Resection-Interposition Arthroplasty, due to the cost of the plate, longer operative time, longer length of stay, and blood loss, but Subtrochanteric Valgus Osteotomy will be preferred by patients due to less pain and better functional and quality of life outcomes.The results of this study are expected to improve outcomes for children with cerebral palsy with painful irreducible dislocated hips.
Ultrasound Screening for Developmental Dysplasia of the Hip in Newborns
Hip DysplasiaThe aim of the randomized controlled trial was to determine whether the addition of a general or of a selective ultrasound screening program resulted in more appropriate criteria for treatment and a reduced prevalence of late DDH compared with clinical examination alone.
Mild Hip Dysplasia
Hip DysplasiaHip dysplasia is a complex problem that exists on a spectrum from mild to severe disease. Periacetabular osteotomy (PAO) remains the gold standard for most patients with dysplasia; however, the procedure is quite invasive making the decision to proceed in cases of mild disease difficult. Hip arthroscopy (HA) is an alternative minimally invasive technique that can be used to address mild dysplasia. Nevertheless, HA has less capability for correction and in rare instances can exacerbate instability in the dysplastic hip. There is a paucity of data examining outcomes between these two treatment strategies for this challenging problem.
Postoperative Analgesic Effect of Two Peripheral Nerve Blocks for Hip Surgery in Pediatrics
PainPostoperative2 moreHip joint surgery for developmental dysplasia of the hip (DDH) in children is extremely painful and associated with considerable postoperative pain despite the use of systemic opioids. Caudal anesthesia and lumbar plexus block (LPB) were still the most common regional anesthesia techniques for perioperative analgesia in children undergoing this type of surgery. recently, pediatric anesthesiologists don't consider choosing both techniques because of potential complications such as intravascular and intrathecal injection, and urine retention. novel peripheral nerve blocks have been advocated in pediatrics to avoid the aforementioned complications such as PEricapsular Nerve Group (PENG) block, Quadratus Lumborum Block (QLB), and Fascia Transversalis Plane Block (FTPB) The objective of the current study is to assess the analgesic efficacy of ultrasound-guided FTPB versus ultrasound-guided PENG block in pediatric patients undergoing open hip surgery for DDH
Efficacy and Safety of Quadratus Lumborum Block Versus Pericapsular Nerve Group Block in Pediatric...
PainPostoperative1 moreSurgical procedure including hip joint surgery is extremely painful and associated with considerable postoperative pain in children despite the use of systemic opioids. Caudal block is a common method used for perioperative pain relief in pediatric lower limb surgeries but carries some complications. Some novel techniques of regional anesthesia were explored including the quadratus lumborum block (QLB), lumbar plexus block, and recently Pericapsular nerve group (PENG) block. The objective of the current trial is primarily to assess the analgesic efficacy of ultrasound-guided trans-muscular QLB versus ultrasound-guided PENG block in pediatric patients undergoing open hip surgery for developmental dysplasia of the hip (DDH)
