Sacral Dysmorphism and Lumbosacral Transitional Vertebrae (LSTV) Review.

Background: Anatomic variation in the relationship between the lumbar spine and sacrum was first described in the literature nearly a century ago and continues to play an important role in spine deformity, low back pain (LBP), and pelvic trauma. This review will focus on the clinical and surgical implications of abnormal lumbosacral anatomy in the context of sacroiliac joint (SIJ) disease, spine deformity, and pelvic trauma.

Methods: A PubMed search using the keywords "lumbosacral transitional vertebrae," "LSTV," "transitional lumbosacral vertebrae," "TLSV," and "sacral dysmorphism" was performed.

Acute total hip arthroplasty versus open reduction internal fixation for posterior wall acetabular fractures in middle-aged patients.

Introduction: Open reduction internal fixation (ORIF) is the standard of care for displaced acetabular fractures, but the inability to achieve anatomic reduction, involvement of the posterior wall, articular impaction, and femoral head cartilaginous injury are known to lead to poorer outcomes. Acute total hip arthroplasty (THA) is a reasonable treatment option for older patients with an acetabular fracture and risk factors for a poor outcome, but it is only described in case series. The purpose of this study is to compare outcomes of ORIF and acute THA in middle-aged patients with an acetabular fracture from a single center.

A biomechanical study comparing minimally invasive anterior pelvic ring fixation techniques to external fixation.

Introduction: INFIX and Pelvic Bridge are two new minimally invasive surgical techniques for unstable pelvic ring injuries, and they have demonstrated early clinical success in small, single-center case-series. The primary objective of this study is to gather evidence speaking to the biomechanical stability of internal bridging methods relative to external fixation, with the expectation of biomechanical equivalence.

Methods: Ten human cadaveric pelvic specimens were dissected free of all skin, fat, organs, and musculature and were prepared with a partially unstable pelvic ring injury (OTA/AO 61-B).

Intra-articular Hematoma Block Compared to Procedural Sedation for Closed Reduction of Ankle Fractures.

Background: Initial treatment for a displaced ankle fracture is closed reduction and splinting. This is typically performed in conjunction with either an intra-articular hematoma block (IAHB) or procedural sedation (PS) to assist with pain control. The purpose of this study was to compare the safety of IAHB to PS and evaluate the efficiency and efficacy for each method.

Displacement of diaphyseal clavicle fractures related to patient position and progressive displacement in the peri-injury period.

Background: The purposes of this study were (1) to determine how supine versus upright patient position affects the measurement of diaphyseal clavicle fracture displacement, (2) to describe the incidence of progressive displacement in the peri-injury period, and (3) to investigate variables associated with the progressive displacement.

Methods: Between 2013 and 2015, patients aged 14 years or older presenting with a diaphyseal clavicle fracture within 7 days of injury were included (N = 50). A well-defined radiographic protocol was established.

Minimally invasive anterior pelvic internal fixation: An anatomic study comparing Pelvic Bridge to INFIX.

Objectives: Anterior external fixation for pelvic ring fractures has shown to effectively improve stability and reduce mortality. However, these fixators can be associated with substantial morbidity such as pin tract infection, premature loss of fixation, and decreased quality of life in patients. Recently, two new methods of subcutaneous anterior pelvic internal fixation have been developed; the INFIX and the Pelvic Bridge.

Publication of Podium Presentations at the Orthopaedic Trauma Association Annual Meetings: 2008-2012.

Objective: To determine journal publication rates of podium presentations from the OTA Annual Meetings between 2008 and 2012.

Methods: Podium presentations from the 2008 to 2012 OTA annual meeting were compiled from the Annual Meeting archives. During December 2016, and Google Scholar were performed using individual keywords in the abstract title and content.
