Review Meta Analysis Comparative StudyInternal Fixation versus Hemiarthroplasty in the Treatment of Unstable Intertrochanteric Fractures in the Elderly: A Systematic Review and Meta-Analysis.
To evaluate the clinical efficacy of internal fixation versus hemiarthroplasty in the treatment of unstable intertrochanteric fractures in the elderly. ⋯ Compared with the internal fixation group, those in the hemiarthroplasty group could carry out weight-bearing training early and implant-related complications were reduced, but it requires longer operation time and there is greater intraoperative blood loss. There is no difference in mortality, the incidence of DVT, non-union, HHS, reoperation, length of hospital stay, and superficial infection. Hemiarthroplasty may be a better choice for unstable intertrochanteric fractures in the elderly.

Comparative StudyPercutaneous Transforaminal Endoscopic Discectomy and Fenestration Discectomy to Treat Posterior Ring Apophyseal Fractures: A Retrospective Cohort Study.
To compare the efficacy and safety of percutaneous transforaminal endoscopic discectomy (PTED) and fenestration discectomy (FD) for posterior ring apophyseal fractures (PRAF). ⋯ While PTED has the same efficacy as FD for treating PRAF, it is associated with shorter operation time, less trauma, and quicker recovery.

Personalized Three-Dimensional Printed Anterior Titanium Plate to Treat Double-Column Acetabular Fractures: A Retrospective Case-Control Study.
To compare the clinical efficacy and safety of a personalized three-dimensional (3D) printed dynamic anterior plate-screw system for the quadrilateral area (DAPSQ) titanium plate and a traditional DAPSQ reconstruction plate in the treatment of double-column acetabular fractures. ⋯ Use of a personalized 3D printed DAPSQ plate has potential advantages in reducing the operation time and blood loss during the treatment of double-column acetabular fractures.

Effect of Percutaneous Endoscopic Lumbar Foraminoplasty of Different Facet Joint Portions on Lumbar Biomechanics: A Finite Element Analysis.
To evaluate the influence of percutaneous endoscopic lumbar foraminoplasty of different facet joint portions on segmental range of motion (ROM) and intradiscal pressure (IDP) of L3 /L4 and L4 /L5 motion segments by establishing three dimensional finite element (FE) model. ⋯ This study provides evidence that the base-facet foraminoplasty of L5 superior facet provided a higher segmental stability compared with the tip-facet foraminoplasty in flexion and axial rotation. Meanwhile, it also shows the two types of foraminoplasty make few differences to the L4/5 segmental biomechanics. Besides, it does not appear to impact the stability of L3 /L4 in six states of forward flexion, backward extension, left lateral bending, right lateral bending, left axial rotation and right axial rotation when superior facet of L5 was partially removed. These findings might be useful in understanding biomechanics of the lumbar spine after foraminoplasty performed on different portions of the facet, thus providing endoscopic surgeons a better reference for operational approach to maintain the function and mobility of the spine.
