Comparative StudySurgical outcomes of cervical myelopathy due to ossification of posterior longitudinal ligament: Anterior decompression and fusion versus posterior laminoplasty.
The purpose of this study was to compare the surgical outcomes of anterior decompression and fusion (ADF) with that of posterior laminoplasty (LAMP) for cervical myelopathy caused by ossification of posterior longitudinal ligament (OPLL). ⋯ Compared with LAMP, ADF shows better improvement of neurological function in patients with cervical myelopathy due to OPLL, especially in patients with segmental-type cervical OPLL.

After-hours elective spine deformity corrective surgery for patients with Adolescent Idiopathic Scoliosis: Is it safe?
The aim of this study was to compare the outcome of after-hours electively planned Posterior Spinal Fusion surgeries for Adolescent Idiopathic Scoliosis (AIS) patients with daytime surgeries. ⋯ After-hours elective spine deformity corrective surgeries for healthy ambulatory patients with AIS were as safe as when they were done during daytime.

Comparative StudyClinical outcomes of dual 3.5-mm locking compression plate fixation for humeral shaft fractures: Comparison with single 4.5-mm locking compression plate fixation.
Recently, several in vitro biomechanical studies that used dual small locking plate fixation for humeral shaft fractures have investigated. However, in vivo studies about dual plate fixation for humeral shaft fractures are limited. The purpose of our study was to report the outcomes of dual small plating for humeral shaft fractures in comparison with those of single large fragment plating. ⋯ For diaphyseal humeral fractures, dual 3.5-mm LCP fixation to the humerus is a possible treatment choice. This method showed satisfactory union rate, ROM, and complication rate, without increasing surgical time, in comparison with the conventional single 4.5-mm LCP fixation. Level of evidence: III.

Screw trajectory affects screw cut-out risk after fixation for nondisplaced femoral neck fracture in elderly patients.
Incidence of femoral neck fracture has risen with the aging of the population and has critical implications with regard to patient death, functional dependence, and social costs. Screw fixation using triangular configurations and calcar placement are still the preferred treatment for nondisplaced femoral neck fracture, to reduce the risk of loss of reduction and nonunion. However, this method is still controversial in terms of the effects of screw trajectory, including parallel or nonparallel configurations, on fixation of femoral neck fractures. This study aimed to compare the incidence of complications between patients who have undergone fixation with a parallel or a nonparallel screw trajectory. ⋯ Our results suggested that fixation with nonparallel screws for nondisplaced femoral neck fracture in elderly and osteoporotic patients might interfere with shortening of the femoral neck along with fracture healing, leaving patients at risk of postoperative screw cut-out from the femoral head.

Uncemented extensive porous titanium-coated long femoral stem prostheses are effective in treatment of Vancouver type B2 periprosthetic femoral fractures: A retrospective mid- to long-term follow-up study.
The aim of this study was to evaluate the mid- to long-term outcomes of revision surgery for Vancouver type B2 periprosthetic femoral fractures (PFFs) after total hip arthroplasty using an uncemented extensive porous titanium-coated long femoral stem prosthesis (solution prosthesis) with or without cortical strut allograft. ⋯ Revision surgery using the solution prosthesis with or without cortical strut allograft is effective in treating Vancouver type B2 PFFs, with satisfactory mid- and long-term clinical and radiological outcomes.
