Determining and Achieving Target Limb Length and Offset in Total Hip Arthroplasty Using Intraoperative Digital Radiography.

Background: Achieving appropriate limb length and offset in total hip arthroplasty (THA) is challenging. Target limb length and offset may not always mean equal radiographic measurements bilaterally. The goal of this study is to introduce a method for determining as well as achieving target limb length and offset using digital radiographic measurements.

Non-locality and the misdiagnosis of Spinal Cord Injury Without Radiographic Abnormality: proof of concept.

Study Design: This is a retrospective review.

Objectives: To validate the concept of "non-locality" to explain cases of Spinal Cord Injury Without Radiographic Abnormality (SCIWORA) previously deemed inexplicable. To investigate and challenge the source data for the SCIWORA hypothesis which has the built-in assumption that a traumatic spinal cord injury (SCI) can only be caused by a local or adjacent spinal column injury and which, therefore, postulates that the pediatric spinal column is inherently more flexible than the spinal cord to explain SCI whenever a local spinal column injury is not detected.

Femoral-Acetabular Mating: The Effect of Femoral and Combined Anteversion on Cross-Linked Polyethylene Wear.

Background: Cross-linked polyethylene (XLPE) has generally low rates of wear and osteolysis at 10 years, but component position may become important with longer follow-up. At 5-13 years, neither acetabular component lateral opening angle nor version were significantly correlated to wear. In the present study, we analyzed the effects of femoral anteversion and combined anteversion on XLPE wear.

Surgeon perspectives on alternative nerve repair techniques.

Background: Over the past five decades, microsuturing has been established as the "gold standard" for nerve repair. Alternative techniques such as fibrin glue, protein "welds", and nerve connectors have been met with variable enthusiasm. While advancements in this area continue, there is little data on surgeon attitude and acceptance of these new techniques.
