Randomized Controlled TrialComparison of the therapeutic effect of teriparatide with that of combined vertebroplasty with antiresorptive agents for the treatment of new-onset adjacent vertebral compression fracture after percutaneous vertebroplasty.
Comparing a prospective group of 32 patients, who underwent percutaneous vertebroplasty (PVP) and who were treated with teriparatide for at least 18 months after a new-onset adjacent vertebral compression fracture (VCF), and compared it with a retrospective group of 33 patients, who received antiresorptive agents combined with repeated PVPs for post-PVP new-onset adjacent VCFs. ⋯ For the treatment of new-onset adjacent VCF after PVPs, the therapeutic effects of teriparatide is better than that of the combined vertebroplasty and an antiresorptive agent in fracture prevention, BMD change, and sustained pain relief.

Randomized Controlled TrialFluoroscopic caudal epidural injections with or without steroids in managing pain of lumbar spinal stenosis: one-year results of randomized, double-blind, active-controlled trial.
A randomized, double-blind, active-controlled trial. ⋯ Caudal epidural injections of local anesthetic with or without steroids may be an effective treatment for a select group of patients with chronic function-limiting low back and lower extremity pain secondary to spinal stenosis.

Randomized Controlled Trial Comparative StudySagittal alignment comparison of Bryan disc arthroplasty with ProDisc-C arthroplasty: a prospective, randomized controlled clinical trial.
A prospective, randomized study of the radiographic outcomes in patients undergoing single-level cervical arthroplasty with Bryan disc and ProDisc-C prosthesis. ⋯ Bryan disc arthroplasty with modified techniques can maintain the lordosis of FSU, whereas ProDisc-C arthroplasty can restore the lordosis of FSU. For the patients with preoperative FSU kyphosis, ProDisc-C arthroplasty may be a better choice to restore the lordosis.

Randomized Controlled Trial Comparative StudyBiomechanical comparison of odontoid plate fixation versus odontoid screw fixation.
Randomized controlled trial with statistically significant difference or statistically no significant difference (Level I). ⋯ Plate fixation of the odontoid process for certain type II odontoid fracture patterns provided a significantly higher biomechanical stability than the technique of odontoid screw fixation. Using a specially designed plate construct fixed with 2 cancellous screws into the body of C2 and an additional cortical screw inserted in the odontoid process, 84% of the original stability of the intact odontoid was restored. Single- or double-screw fixation of the odontoid only restored approximately 50% of the original strength.

Randomized Controlled TrialClinical outcomes of Bryan cervical disc arthroplasty a prospective, randomized, controlled, single site trial with 48-month follow-up.
Prospective, randomized, controlled. Level 1 evidence. ⋯ At 48 months, cervical arthroplasty with the Bryan cervical disc prosthesis continues to compare favorably to ACDF at our institution. There has been no degradation of functional outcomes from 24 to 48 months for NDI, VAS of neck and arm, and SF-36. There has been a lower incidence of secondary surgeries for the Bryan arthroplasty cohort to date.
