Comparative StudyRadial head reconstruction in elbow fracture-dislocation: monopolar or bipolar prosthesis?
Monopolar and bipolar radial head prosthetic arthroplasties have been used successfully to treat elbow fracture-dislocation with unsalvageable radial head fractures. The relative stability of these two designs in different clinical situations is a topic of ongoing investigation. ⋯ The data from our cadaveric model support the use of either implant type in terrible triad injuries if the collateral ligaments are intact or reconstructed.

Heterotopic ossification of the elbow treated with surgical resection: risk factors, bony ankylosis, and complications.
Heterotopic ossification is the most common extrinsic cause of elbow contracture and may lead to clinically important stiffness, and rarely, complete bony ankylosis. Surgery sometimes is performed to treat this problem, and published reports differ regarding the factors that are associated with success or failure after this operation and whether the procedure is effective for patients with elbow ankylosis. ⋯ Level IV, therapeutic study. See the Instructions for Authors for a complete description of levels of evidence.

Comparative StudyNationwide Inpatient Sample and National Surgical Quality Improvement Program give different results in hip fracture studies.
National databases are being used with increasing frequency to conduct orthopaedic research. However, there are important differences in these databases, which could result in different answers to similar questions; this important potential limitation pertaining to database research in orthopaedic surgery has not been adequately explored. ⋯ Level II, prognostic study. See the Instructions for Authors for a complete description of levels of evidence.

ReviewMinimally invasive surgical techniques in adult degenerative spinal deformity: a systematic review.
Minimally invasive surgery (MIS) approaches have the potential to reduce procedure-related morbidity when compared with traditional approaches. However, the magnitude of radiographic correction and degree of clinical improvement with MIS techniques for adult spinal deformity remain undefined. ⋯ The literature on these techniques is scanty; only two of the 13 studies that met inclusion criteria were considered high quality; CT scans were not generally used to evaluate fusion, deformity correction was inconsistent, and complication rates were high. Future directions for analysis must include comparative trials, longer-term followup, and consistent use of CT scans to assess for fusion to determine the role of MIS techniques for adult spinal deformity.
