Randomized Controlled Trial Multicenter Study Comparative StudyDuration of symptoms resulting from lumbar disc herniation: effect on treatment outcomes: analysis of the Spine Patient Outcomes Research Trial (SPORT).
The purpose of the present study was to determine if the duration of symptoms affects outcomes following the treatment of intervertebral lumbar disc herniation. ⋯ Increased symptom duration due to lumbar disc herniation is related to worse outcomes following both operative and nonoperative treatment. The relative increased benefit of surgery compared with nonoperative treatment was not dependent on the duration of the symptoms.

Randomized Controlled Trial Comparative StudyThe effect of weekly risedronate on periprosthetic bone resorption following total hip arthroplasty: a randomized, double-blind, placebo-controlled trial.
Bone loss leading to late-occurring periprosthetic femoral fracture is a mode of failure in cementless total hip arthroplasty. The aim of this trial was to investigate the effect of a bisphosphonate, risedronate, on femoral periprosthetic bone resorption following total hip arthroplasty in patients with osteoarthritis of the hip. ⋯ Risedronate taken once weekly for six months following total hip arthroplasty was effective in reducing periprosthetic bone resorption around an uncemented femoral stem up to one year after surgery but had no discernible effect on implant migration or clinical outcome. Future studies of bisphosphonate treatment following total hip arthroplasty should focus on clinically relevant end points such as the risks of fracture and revision arthroplasty.

Randomized Controlled Trial Comparative StudyA prospective randomized controlled trial comparing occupational therapy with independent exercises after volar plate fixation of a fracture of the distal part of the radius.
The effect of formal occupational therapy on recovery after open reduction and volar plate fixation of a fracture of the distal part of the radius is uncertain. We hypothesized that there would be no difference in wrist function and arm-specific disability six months after open reduction and volar plate fixation of a distal radial fracture between patients who receive formal occupational therapy and those with instructions for independent exercises. ⋯ Prescription of formal occupational therapy does not improve the average motion or disability score after volar locking plate fixation of a fracture of the distal part of the radius.
