Clinical results and functional outcomes of primary and revision spinal deformity surgery in adults.
Few studies have examined the postsurgical functional outcomes of adults with spinal deformities, and even fewer have focused on the functional results and complications among older adults who have undergone primary or revision surgery for spinal deformity. Our goal was to compare patient characteristics, surgical characteristics, duration of hospitalization, radiographic results, complications, and functional outcomes between adults forty years of age or older who had undergone primary surgery for spinal deformity and those who had undergone revision surgery for spinal deformity. ⋯ Therapeutic Level IV.

Randomized Controlled Trial Multicenter Study Comparative StudyOperative versus nonoperative treatment of displaced intra-articular calcaneal fractures: a prospective, randomized, controlled multicenter trial.
We conducted a prospective, randomized, controlled multicenter trial to compare operative with nonoperative treatment of displaced intra-articular calcaneal fractures. ⋯ Therapeutic level II. See instructions for authors for a complete description of levels of evidence.

Multicenter StudyClinical presentation of posterolateral rotatory instability of the elbow in children.
Posterolateral rotatory instability is a type of ulnohumeral instability seen following elbow trauma. It is caused by a deficiency in the lateral collateral ligament complex that allows the radius and ulna to subluxate as a single unit with respect to the distal part of the humerus. There are few studies on this type of instability in children. Our purpose was to evaluate cases of posterolateral rotatory instability in children to better understand its presentation and manifestation as compared with those in adults. ⋯ Therapeutic level IV.

Incidence of displacement after nondisplaced distal radial fractures in adults.
It is standard practice to closely monitor distal radial fractures treated nonoperatively to ensure that there is no fracture displacement. Patients are often asked to initially return weekly for radiographs. To our knowledge, nondisplaced distal radial fractures in adults have not been specifically evaluated to determine if this level of vigilance is required. If this subset of fractures is unlikely to displace, the cost, radiation exposure, and inconvenience of weekly office visits could be spared. ⋯ Prognostic level III. See Instructions for authors for a complete description of levels of evidence.
