Active clinical trials for "Bone Marrow Diseases"

Cancer which has spread to the bone, causing bone metastases (bone tumours) can weaken bone health and increase risk of fractures (breaks). Consequently, patients can be unsure whether to exercise and health professionals can be unsure what exercise advice is suitable. Despite this, it is well known that exercise improves quality-of-life for patients with bone metastases and therefore it is important that exercise is prescribed to these patients. This study aims to increase understanding of the link between daily exercise and risk of fracture in patients with bone metastases.

Model of this study is a combined both retrospective chart review and follow up survey. Data of 4 hospitals will be used to find out the efficacy of conservative treatment in cervical myelopathy.

More than half of the middle-aged population has radiologic evidence of cervical spondylosis (Irvine 1965) and a subset of this population develops cervical spondylotic myelopathy (CSM), a condition in which the spinal cord is impaired, either by direct mechanical compression or indirectly by arterial deprivation and/or venous stasis. In this study we aim to test the hypothesis that diffusion tensor imaging can provide prognostic information on the integrity of the spine in these patients which is unavailable from conventional MRI images

Enhanced recovery after surgery (ERAS) strategy has been used in the patient management of different diseases. This study aims to evaluate the effectiveness of ERAS in the perioperative period of posterior approach of cervical spine operation among patients with CSM.

Radiculopathy and/or myelopathy due to cervical degenerative disc disease are increasingly common pathologies in our ageing population. Both can be treated non-surgically or surgically. The most commonly used neurosurgical treatment is anterior cervical discectomy with or without fusion. The goal is to achieve neural decompression of the operated segment in both procedures. However, due to this fusion and reduced mobility of the cervical spine at the level of the intervention, adjacent segment disease may occur. This can lead to new symptoms like radiculopathy and/or myelopathy at an adjacent level which requires reoperation in about 2/3 of patients. Reoperations are burdensome for patients and have a socio-economic impact due to the costs of hospital admissions, operations, and secondary costs such as work-absenteeism. The primary objective of this retrospective study is to determine the occurrence of adjacent segment disease after a single- or multi-level anterior cervical discectomy with fusion procedure for radiculopathy and/or myelopathy in the investigators' centre and to compare this to the incidence in literature. The investigators also look at the risk of adjacent segment disease after different anterior surgical techniques, such as anterior cervical discectomy, anterior cervical discectomy with fusion and plating, and corpectomy. As a secondary outcome they aim to determine risk factors predicting the occurrence of adjacent segment disease.

This is a randomized controlled trial to assess the use of rigid neck collar postoperatively. It consists of patients with cervical myelopathy undergoing open-door laminoplasty with titanium arch plates. Patients are divided into two groups: one group are not using rigid neck collar whereas the second group of patients wear rigid neck collar for three weeks postoperatively. Both groups of patients will then be assessed at fixed intervals. Clinical assessments include the cervical spine range of motion, any axial neck pain and also a full neurological examination. Radiographs will be used to assess for any complications. Cervical spine alignment and relevant questionnaires will be done and recorded. These results will help to conclude whether we can avoid the use of rigid cervical collars postoperatively, in view of the associated problems arising from restricted neck movement.

Cervical myelopathy is commonly associated with degenerative spinal disease. Dysfunction of the autonomic nervous system is also evident in many cases of cervical myelopathy. Autonomic dysfunction may result in haemodynamic instability and hypotension under anaesthesia. It is important to maintain adequate mean arterial pressure in order to perfuse the spinal cord and prevent cord ischemia. Heart rate variability, the physiological variations of the differences between heart beats, has been used to diagnose autonomic dysfunction. In patients with cervical myelopathy it may enable the anaesthetist to predict hypotension thereby allowing for early treatment and prevention of spinal cord ischemia.

The purpose of this study is to compare 18F-Fluoride PET bone scans to traditional 99mTc-MDP bone scan to determine if one is better for diagnosing bone metastases.

The purpose of this study is to determine if denosumab is non-inferior to zoledronic acid in the treatment of bone metastases in subjects with advanced breast cancer.

The purpose of the study is to determine the cost-effectiveness of different surgical strategies to treat cervical spondylotic myelopathy. The study will use data generated from the CSM-S Trial (NCT02076113). To determine if laminoplasty is more cost-effective compared to dorsal fusion or ventral fusion surgery. To determine the relative cost-effectiveness between anterior cervical discectomy and fusion (ACDF), posterior instrumented cervical fusion (PCF), and cervical laminoplasty.
