Epidemiology, Management, and Outcomes of Large and Small Native Joint Septic Arthritis in Adults.

Background: Native joint septic arthritis (NJSA) is poorly studied. We describe the epidemiology, treatment, and outcomes of large joint NJSA (LNJSA) and small joint NJSA (SNJSA) in adults at Middlemore Hospital, Auckland, New Zealand.

Methods: This was a coding-based retrospective study of patients ≥16 years old admitted between 2009 and 2014.

Radiologic landmark accuracy for optimum coronal placement of total disc arthroplasty in the lumbar spine.

Objective: This study was performed to determine which of the radiographic markers visible on an anteroposterior (AP) radiograph of the spine-the vertebral body, the pedicles, and the spinous process-provided the most accurate guide to correctly placing an intervertebral disc replacement in the coronal midline.

Method: The coronal midline was defined as the perpendicular bisector of a line drawn between the midpoints of the two facet joints. Axial CT images were reconstructed from 35 abdominal and renal computed tomograms to compare how consistently the midpoints of the above structures fell on the coronal midline.

Fate of the infrapatellar branch of the saphenous nerve post total knee arthroplasty.

Background: The infrapatellar branch of the saphenous nerve is a known cause of morbidity following knee surgery. The incidence of sensory changes following total knee arthroplasty, and its effect on patient satisfaction with arthroplasty surgery remain undocumented. Our aim was to document the incidence of infrapatellar nerve palsy following total knee arthroplasty and its effect on patient satisfaction.
