Active clinical trials for "Fractures, Bone"

To assess the analgesic and respiratory effect of continuous Erector Spinae Plane block versus Thoracic Epidural in patients with multiple fracture ribs.

A proof of concept randomized controlled trial (RCT) only evaluated the National University of Singapore's (NUS) T-Rehab tele-rehabilitation (TR) system at a home setting where rehabilitation was provided on an individual level. The previous RCT was also limited to stroke patients. In addition to stroke, there are many other conditions (such as fractures, lower limb joint replacement, musculoskeletal conditions) require and benefit from rehabilitation. The primary aims of the pilot evaluation study are: (i) To document patient adherence to TR, compared to usual care (ii) To estimate the extent to which TR improves functional status, compared to usual care and (iii) To estimate the cost effectiveness of TR, compared to usual care in eight different health conditions in Singapore.

Fascia Iliaca Compartment Block (FICB) is a popular regional anaesthetic technique for surgical procedures involving the hip joint and femur. The FICB may be thought of as an anterior approach to the lumbar plexus where local anaesthetic is injected proximally beneath the fascia iliaca, with the aim of blocking the femoral nerve ,obturator nerve and lateral cutaneous nerve of thigh simultaneously. In addition to providing effective analgesia, peripheral nerve blocks are increasingly preferred especially in frail patient groups such as the geriatric population which femoral fractures are the most common, because of their advantages such as avoiding the complications of neuraxial anesthesia and the side effects of opioids. FICB can be applied with ultrasound-guided suprainguinal or infrainguinal approaches. Studies on the superiority of the two methods used in clinical practice are limited. In this study, it is aimed to compare the suprainguinal (Group S) and infrainguinal (Group I) approaches of FICB applied in the preoperative period in femoral fractures in which spinal anesthesia method was chosen. These two methods will be compared in terms of postoperative pain scores (11-point numeric scale), morphine consumption (by intravenous patient controlled analgesia for postoperative 24 hours) and possible side effects-complications.

This study is designed as a single-blind RCT in 80 postmenopausal women to compare the effect of immediate administration of daily calcium supplementation (1000 mg calcium) or two daily dosages of calcium + vitamin D (1000 mg calcium + 880 IU vitamin D or 1000 mg calcium + 1760 IU vitamin D) to standard care (administration of vitamin D3 12 weeks after fracture) in terms of calculated bone strength based on analysis of cortical and trabecular bone parameters using HR-pQCT, fracture healing and functional outcome.

This pilot study will evaluate the feasibility of implementing an intervention in the home setting that is specifically designed to coach and mentor caregivers as they assist individuals with Alzheimer's disease and related dementia (ADRD) who have fractured a hip to perform everyday activities and engage in more physical activity.

This is a randomized controlled, observer blinded trial to study the beneficial effect of nutritional supplementation in elderly Hong Kong patients after hip fracture surgery during rehabilitation and at 4 weeks follow up. The control group will receive Calcium and Vitamin D supplementation whereas the intervention group will receive a moderately high dose protein nutritional supplementation in addition to Vitamin D and Calcium. Both groups undergo the same rehabilitation program and dietary counseling before discharge. They are followed up 4 weeks after discharge or completion of supplementation. The outcome parameters are nutritional parameters and rehabilitation outcomes.

Osteoporosis is a very frequent and easily treatable disease. Rates of treatment of affected patients is very low, as few high risk patients initiate treatment and only a minority of those pursue treatment for long enough time to prevent fractures. Patients presenting a fragility fracture after 50 years of age are at high risk of osteoporosis and may represent the ideal group of patients in which intervention aimed at improving initiation and persistence on treatment will be most effective. Our first hypothesis is that the availability of a dedicated nurse practitioner to identify patients with fragility fractures among patients presenting at fracture clinics of orthopedic surgeons will increase markedly the rate of identification of osteoporosis. Our second hypothesis is that giving to both the patient and its primary health practitioner (PHP) the patient's clinical, biological and radiological data along with individualized care suggestions will yield significantly better results than giving to the patient and its PHP generic information on osteoporosis risk, investigation and treatment.

A higher number than expected of patients with hip fracture have only insufficient analgesic effect of a femoral nerve block, which is the nerve block commonly used for this group of patients. One of the possible causes of this failure to provide analgesia from a single nerve block could be the that other nerves are involved in transmitting the pain signal. One of the nerves that is believed to give off branches to the hip is the obturator nerve. With ultrasound it is possible to make a selective proximal nerve block of the obturator nerve. The aim of this trial is to test the analgesic effect of a femoral nerve block i combination with an obturator nerve block compared to femoral nerve block alone in a randomized and placebo controlled design.

Proximal humeral fractures are with an incidence of 4-5% the third most common fractures in the elderly. Compared to fractures of the upper limb it is the second most common fracture after distal radial fractures. 65% of all patients with a proximal humeral fracture are older than 60 years. Being aware of the demographic change there will even be an increase of incidence of these fractures. Kannus et al. showed an incidence of 298 per 100,000 in the at least 80 years old patients in 2007. Palvanen et al. predict an increase of incidence of 50% until 2030. Approximately 80% of all humeral fractures are minimally or non-displaced and can be treated conservatively with a good functional result. In 20% of humeral fractures there is an indication for surgical treatment according to the modified Neer-Criteria. These criteria are fulfilled if there is an angulation of at least 45 degrees between fracture fragments, a displacement of the humeral shaft against the humeral head of at least 1 cm or a dislocation of the tuberculum of at least 5 mm. Up to now there is evidence for superiority of any surgical treatment in literature. At the moment the most frequently used surgical technique for treatment of proximal humeral fractures is the angle stable plate fixation. There are various publications concerning this topic published by the investigators research group. In their 10-years results a majority of patients showed excellent and good, but also 16% showed unsatisfactory results after locking plate fixation. Main risk for poor outcome was revision surgery caused by secondary displacement (14%) which is also confirmed by results of other studies. In a further study investigators could show that there is a higher risk for secondary displacement in 2-part-fractures with a gross primary dislocation or a large metaphyseal fracture zone (AO 11-A3), especially in osteoporotic patients. More over these are common fractures and because of that a problem in surgical treatment. A secondary varus dislocation of the head fragment and cutting-out are the most common complications of angle stable locking plates in AO 11-A3 fractures of the elderly. The primary reason for this mechanism of failure is certain instability of transmetaphyseal fractures in the region of the surgical neck caused by loss of impaction in a porous spongiosa. Because of that the forces on the head screws are high while the so called screw-bone-interface is rather weak after a surgical treatment. Currently there exist various approaches to avoid a failure of the primary screw implantation. One possibility to increase the stability of the screw-bone-interface is the cement augmentation of the screw tips. To date there exist no clinical study that reports the results of locking plate fixation and the augmentation of cannulated head screws although it is a widely used method in everyday surgery, especially in the elderly. A second possibility to prevent secondary displacement after surgical treatment of 2-fragment-fractures is the use of an intramedullary nails. A further development of intramedullary nails is multiplanar nailing. Screws can be inserted in various different levels and directions which can lead to a clearly higher stability. A comparison of these two treatment options augmented locking plate versus multiplanar angle stable locking nail in 2-part proximal humeral fractures has not been carried out up to now.

Nonunion of long bones would occur in almost 10% of fractures and because of its long term and complicated treatment, is known as a therapeutic challenge for both of the surgeons and patients. Cell therapy is useful in treatment of nonunion and mesenchymal stromal/stem cells are the best candidates for this kind of treatment. Percutaneous implantation of autologous bone marrow derived mesenchymal stromal/stem cell in combination with PL will be done in 30 patients with tibia nonunion. The other 30 patients as the control group will receive placebo. The patients will be followed at 2weeks, 3months, 6m and 12 months after implantation. The Spss(v16) software will be used for data analysis.
