Treatment of degenerative spondylolisthesis by instrumented posterolateral versus instrumented posterolateral with transforaminal lumbar interbody single-level fusion.

Background: The purpose of this study was to compare outcomes of patients with degenerative spondylolisthesis treated by posterolateral lumbar fusion (PLF) versus PLF with transforaminal lumbar interbody fusion (PLF + TLIF). Studies of PLF versus PLF + TLIF have shown either equivalence or support for PLF + TLIF in lumbar spine surgery. Many are heterogeneous in the conditions treated, with few considering only spondylolisthesis of degenerative origin.

Radiographic Outcomes of Hemiepiphyseal Stapling for Distal Radius Deformity Due to Multiple Hereditary Exostoses.

Background: Multiple hereditary exostoses (MHE) affect the distal forearm in 30% to 60% of patients with this condition. Many surgical interventions have been described, but treatment is controversial. We present the radiographic results of low risk, minimally invasive hemiepiphyseal stapling of the distal radius to correct the joint angulation caused by MHE through growth modulation.

Can we continue to ignore gender differences in performance on simulation trainers?

Background: There are differences between the genders in their innate performances on simulation trainers, which may impair accurate assessment of psychomotor skills.

Methods: The performance of fourth-year students with no exposure to the Minimally Invasive Surgical Trainer compared based on gender, and other psychomotor skills.

Results: Our study included 16 male and 16 female students.
