Randomized Controlled Trial Multicenter Study Comparative StudyPrognostic factors for predicting outcomes after intramedullary nailing of the tibia.
Prediction of negative postoperative outcomes after long-bone fracture treatment may help to optimize patient care. We recently completed the Study to Prospectively Evaluate Reamed Intramedullary Nails in Patients with Tibial Fractures (SPRINT), a large, multicenter trial of reamed and unreamed intramedullary nailing of tibial shaft fractures in 1226 patients. Using the SPRINT data, we conducted an investigation of baseline and surgical factors to determine any associations with an increased risk of adverse events within one year of intramedullary nailing. ⋯ Prognostic Level II.

Randomized Controlled Trial Comparative StudyDoes subacromial injection of a local anesthetic influence strength in healthy shoulders?: a double-blinded, placebo-controlled study.
Subacromial injection of a local anesthetic is used to eliminate pain as a confounding factor in clinical assessment of abduction strength in shoulders with a suspected rotator cuff tear. If strength remains diminished despite pain relief, a rotator cuff tear is likely. The effect of injecting local anesthetic into the subacromial space on the strength of a normal shoulder is unknown, although it could affect strength by impairing suprascapular or axillary nerve function. We hypothesized that subacromial injection of a local anesthetic could decrease shoulder abduction and/or external rotation strength, resulting in physical examination findings that could mislead the clinician. ⋯ Diagnostic Level I.
