Randomized Controlled Trial Comparative StudyOrthopaedic management improves the rate of early osteoporosis treatment after hip fracture. A randomized clinical trial.
Although osteoporosis is strongly associated with hip fractures, the initiation of osteoporosis treatment following hip fractures occurs at surprisingly low rates of between 5% and 30%. Currently, most patients receiving treatment have been referred back to their primary care physician for osteoporosis management. The purpose of this study was to compare the effect of osteoporosis management initiated by the orthopaedic team and osteoporosis management initiated by the primary care physician on the rates of treatment at six months. ⋯ An active role by orthopaedic surgeons in the management of osteoporosis improves the rate of treatment at six months following a hip fracture.

Randomized Controlled Trial Multicenter Study Comparative StudyCervical disc arthroplasty compared with arthrodesis for the treatment of myelopathy.
Although there have been case reports describing the use of cervical disc arthroplasty for the treatment of myelopathy, there is a concern that motion preservation may maintain microtrauma to the spinal cord, negatively affecting the clinical results. As we are not aware of any studies on the use of arthroplasty in this scenario, we performed a cross-sectional analysis of two large, prospective, randomized multicenter trials to evaluate the efficacy of cervical disc arthroplasty for the treatment of myelopathy. ⋯ We found that patients in both the arthroplasty and arthrodesis groups had improvement following surgery; furthermore, improvement was similar between the groups, with no worsening of myelopathy in the arthroplasty group. While the findings at two years postoperatively suggest that arthroplasty is equivalent to arthrodesis for the treatment of cervical myelopathy for a single-level abnormality localized to the disc space, the present study did not evaluate the treatment of retrovertebral compression as occurs in association with ossification of the posterior longitudinal ligament, and we cannot comment upon the treatment of this condition.

Review Meta AnalysisThe use of antifibrinolytic agents in spine surgery. A meta-analysis.
Antifibrinolytic agents have been shown to decrease the blood loss associated with major orthopaedic surgical procedures. Spine surgery, particularly procedures performed for deformity correction and procedures involving long arthrodesis constructs, can be associated with a large amount of blood loss requiring blood transfusions. The purpose of the present study was to determine if antifibrinolytic agents reduced blood transfusions in patients managed with spine surgery and to see if one agent had a greater effect than another. ⋯ Aprotinin, tranexamic acid, and epsilon-aminocaproic acid are effective for reducing blood loss and transfusions in patients managed with spine surgery. With the exception of aprotinin, the side-effect profiles of these agents have not been shown to cause any substantial morbidity or to increase the rate of thromboembolic events. Epsilon-aminocaproic acid had a greater effect on reducing blood transfusions as the complexity of surgery increased. The surgeon and/or the anesthesiologist should consider the use of antifibrinolytic agents for patients undergoing spinal procedures in which a large amount of blood loss can be expected; however, at the present time, this is not a United States Food and Drug Administration-approved indication for these agents.

Randomized Controlled Trial Meta AnalysisElectrical stimulation for long-bone fracture-healing: a meta-analysis of randomized controlled trials.
Bone stimulation represents a $500 million market in the United States. The use of electromagnetic stimulation in the treatment of fractures is common; however, the efficacy of this modality remains uncertain. We conducted a systematic review and meta-analysis of randomized controlled trials to evaluate the effect of electromagnetic stimulation on long-bone fracture-healing. ⋯ While our pooled analysis does not show a significant impact of electromagnetic stimulation on delayed unions or ununited long-bone fractures, methodological limitations and high between-study heterogeneity leave the impact of electromagnetic stimulation on fracture-healing uncertain.
