Does Screw Order Matter? A Technique Tip to Prevent Loss of Fracture Reduction during Surgical Fixation of Lateral Malleolus Fractures.

When obtaining surgical fixation of lateral malleolus fractures, a cortical lag screw is commonly used to obtain anatomic reduction. Subsequently, a neutralization plate is applied. Slight loss of fracture reduction after plate placement occasionally occurs.

Factors Associated With Implant Removal Following Plate-and-Screw Fixation of Isolated Metacarpal Fractures.

Purpose: The incidence of and associated risk factors for implant removal following the plate-and-screw fixation of metacarpal shaft fractures have not been well described. The primary objective of our study was to identify implant-related radiographic parameters associated with implant removal in patients treated with the plate-and-screw fixation of isolated, displaced metacarpal fractures at 2 years of follow-up. The secondary objective of our study was to identify patient-related factors associated with implant removal.

Early Weight Bearing after Distal Femur Fracture Fixation.

Objectives: To assess outcomes following early weight bearing after distal femur fracture fixation with locked lateral plating.

Design: Retrospective cohort study.

Setting: Two Level 1 Academic Trauma Centers.

Fixed (Congenital) Patellar Dislocation.

Congenital dislocation of the patella is a rare condition characterized by lateral dislocation of the patella that is irreducible without surgical correction. Although there is no clear inheritance pattern, it is associated with several congenital syndromes. Patients often demonstrate flexion contracture, loss of active knee extension, increased tibial external rotation, and absent patella in the trochlea.

Duty cycling influences current generation in multi-anode environmental microbial fuel cells.

Improving microbial fuel cell (MFC) performance continues to be the subject of research, yet the role of operating conditions, specifically duty cycling, on MFC performance has been modestly addressed. We present a series of studies in which we use a 15-anode environmental MFC to explore how duty cycling (variations in the time an anode is connected) influences cumulative charge, current, and microbial composition. The data reveal particular switching intervals that result in the greatest time-normalized current.
