Randomized Controlled Trial Comparative StudySingle-injection or continuous femoral nerve block for total knee arthroplasty?
The ideal local anesthetic regime for femoral nerve block that balances analgesia with mobility after total knee arthroplasty (TKA) remains undefined. ⋯ Level II, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.

Randomized Controlled TrialDoes limb preconditioning reduce pain after total knee arthroplasty? A randomized, double-blind study.
Total knee arthroplasty (TKA) can be associated with considerable postoperative pain. Ischemic preconditioning of tissue before inducing procedure-related underperfusion may reduce the postoperative inflammatory response, which further may reduce associated pain. ⋯ Given the ease of this intervention, ischemic preconditioning may be considered as part of a multimodal analgesic strategy. However, more study into the impact of different preconditioning strategies, elucidation of mechanisms, safety profiles, and cost-effectiveness of this maneuver is needed.

Randomized Controlled Trial Comparative StudyDeltoid-split or deltopectoral approaches for the treatment of displaced proximal humeral fractures?
Proximal humeral fractures are mainly associated with osteoporosis and are becoming more common with the aging of our society. The best surgical approach for internal fixation of displaced proximal humeral fractures is still being debated. ⋯ Level II, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.

Peripheral nerve blocks in shoulder arthroplasty: how do they influence complications and length of stay?
Regional anesthesia has proven to be a highly effective technique for pain control after total shoulder arthroplasty. However, concerns have been raised about the safety of upper-extremity nerve blocks, particularly with respect to the incidence of perioperative respiratory and neurologic complications, and little is known about their influence, if any, on length of stay after surgery. ⋯ Level IV, therapeutic study. See Instructions for Authors for a complete description of levels of evidence.

Review Case ReportsPulmonary cement embolization after vertebroplasty requiring pulmonary wedge resection.
Pulmonary cement embolization after vertebroplasty is a well-known complication but typically presents with minimal respiratory symptoms. Although this rare complication has been reported, the current literature does not address the need for awareness of symptoms of potentially devastating respiratory compromise. ⋯ Pulmonary cement embolism is a potentially serious complication of vertebroplasty. If a patient has chest pain or respiratory difficulty after the procedure, chest radiography and possibly advanced chest imaging studies should be performed immediately.
