Filter by:The aim of this study is to compare the efficacy of airway topical anesthesia with nebulization to the spray-as-you-go technique using dexmedetomidine and lidocaine mixture to achieve upper airway anesthesia in TMJ ankylosis patients.
The study is to determine whether one (or two) new method(s) will help treat dental ankylosis. This study tackles the challenging tooth-bone fusion disorder of ankylosis. In growing patients, ankylosis causes significant developmental bone defects due to its inhibition of the vertical growth of the affected alveolar bone area.
the most commonly used protocol in the management of TMJ ankylosis is Kabans protocol in which 1.5 to 2 cm aggressive resection of bone is recommended which may lead to gap between cranial base and condyle of mandible.1 However, there are certain disadvantages associated with aggressive gap arthroplasty such as pseudo articulation with shortening of the mandibular ramus, premature occlusion on the affected side with a contralateral open bite in unilateral cases,2 in bilateral cases gagging of the posterior teeth and anterior open bite.3 Few studies in the literature available agreed that minimum gap arthroplasty i.e. 5 to 8 mm of gap is sufficient for TMJ movements in all planes and recurrence of ankylosis is likely to be prevented by interposed material (graft)4 .So, a randomized control study to compare outcomes of minimal gap arthroplasty with aggressive gap arthroplasty for management of TMJ ankylosis is planned.
In the midst of the opioid crisis, the use of non-narcotic pain medication has garnered increased interest, particularly in the field of orthopaedic surgery, where narcotic medications are routinely prescribed postoperatively. Nonsteroidal anti-inflammatory drugs (NSAIDs) have the potential to serve as an adjunct analgesic, but many orthopaedic surgeons have viewed NSAIDs with hesitancy because of evidence that they can lead to delayed bone healing. When evaluating bone healing across different NSAID formulas, ketorolac was found to cause no delay and lead to better union rates when compared to controls and other NSAIDs, respectively. Previous studies in the orthopaedic spine and trauma literature have suggested a detrimental effect of NSAIDs, specifically ketorolac, with regards to bone healing, while others have reported no delay in healing. A recent study from our institution found no detrimental effects on the healing of ankle fractures with the use of ketorolac in the immediate postoperative period. Additionally, the use of ketorolac was associated with less reliance on narcotic pain medications. The purpose of this prospective randomized study is to evaluate the use of ketorolac on postoperative pain, opioid requirements, patient satisfaction, complication/reoperation rates, and delayed and/or nonunion rates in patients undergoing fusion of their first metatarsophalangeal joint (1st MTPJ) for treatment of end-stage arthritis.
Study purpose is to compare the outcome after total wrist arthrodesis (TWA) with proximal carpal row (Proximal Row Carpectomy = PRC) as bone graft versus iliac crest cancellous bone graft. Patients with radiologically and clinically confirmed advanced osteoarthritis are randomized (1:1 computer generated sequence with random block size) to two parallel groups and will undergo either total wrist arthrodesis with PRC or TWA with iliac crest bone grafting. Baseline data is collected preoperatively and is a follow-up visits at every 6 weeks after the surgery is arranged until the wrist is fused. The primary end-point is 6 months and the primary outcome is fusion rate.
Hypothesis：Computer-aided design virtual mandibular position is feasible for costochondral graft growing and occlusion stabilizing in the one-stage treatment of children temporomandibular joint ankylosis (TMJA) or condyle absence with jaw deformity. Methods: The inclusion criteria is children patients younger than 12 years old with unilateral TMJA or condyle absence. A virtual mandibular position is designed preoperatively according to the CT data of jaw and dentition. 3D printed templates and occlusal splints are used to guide the costochondral graft and mandibular position. During surgery, the affected ramus is reconstructed with costochondral grafting under the virtual mandibular position. After surgery, the occlusal splint is fixed to maxilla at least one month, and then, replaced by orthodontic functional appliance to promote downward growth of the maxilla. Occlusion, facial symmetry, costochondral graft growing would be evaluated and analysed until adulthood.
Patients diagnosed with chronic SIJ pain that can be treated by sacroiliac joint fusion or radiofrequency ablation. The radio frequency ablation is performed using either conventional or "cooled" techniques aimed at the S1-S3 lateral branches and the L5 dorsal ramus. Minimally invasive sacroiliac joint consists of implanting 2 to 3 metallic implants inside the SIJ to increase the stability and eventually fuse the SIJ. This randomized controlled trial aims at comparing treatment success at 6-month follow-up time-point after minimally invasive sacroiliac joint fusion and radiofrequency ablation for chronic SIJ dysfunction.
The purpose of this study is to evaluate the safety and clinical effect of mesenchymal stem cells (MSCs) derived from human bone marrow at a dose of 1.0E+6 MSC/kg in subject for the therapy of Ankylosing spondylitis (AS) and to compare the efficacy of MSCs and Etanercept to treat this disease.
Two-year (2 year) information regarding the performance of the commercially available Actis™ Total Hip System in order to obtain and evaluate the clinical outcomes on a series of cementless primary total hip arthroplasty (THA) and hemi-hip arthroplasty procedures using clinical, radiographic and device and procedure related adverse event assessments.
The purpose of the SI Joint Fusion and Decortication Using the SImmetry System study is to evaluate the SImmetry Sacroiliac Joint Fusion System for fusion of the SI joint and relief of SI joint pain symptoms.
