Novel Treatment Options for the Surgical Management of Young Femoral Neck Fractures.

J Orthop Trauma 2019 Jan;33 Suppl 1:S33-S37

Orthopaedic Trauma Service, Hospital for Special Surgery, New York, NY.

In physiologically young patients with displaced femoral neck fractures, surgical treatment is aimed at achieving fracture union while preserving native hip anatomy and biomechanics. The intracapsular environment, tenuous vascular supply, and unfavorable hip biomechanics contribute to the high complication rates seen after osteosynthesis of these fractures. Conventional fixation methods for osteosynthesis of femoral neck fractures include multiple cancellous screws, fixed-angle dynamic implants, and fixed-angle length-stable constructs. Read More

Biomechanics of Femoral Neck Fractures and Implications for Fixation.

J Orthop Trauma 2019 Jan;33 Suppl 1:S27-S32

*Institute for Biomechanics, BG Unfallklinik Murnau, Murnau, Germany; and †Institute for Biomechanics, Paracelsus Medical University Salzburg, Salzburg, Austria.

Fractures of the femoral neck can occur in young healthy individuals due to high loads occurring during motor vehicle accidents, impacts, or falls. Failure forces are lower if impacts occur sideways onto the greater trochanter as compared with vertical loading of the hip. Bone density, bone geometry, and thickness of cortical bone at the femoral neck contribute to its mechanical strength. Read More

Technologies for Young Femoral Neck Fracture Fixation.

J Orthop Trauma 2019 Jan;33 Suppl 1:S20-S26

Department of Orthopaedic Surgery, Wake Forest University School of Medicine, Winston-Salem, NC.

Fixation of young femoral neck fractures represents a challenge in the field of orthopaedic trauma surgery. Conventional methods, including cannulated screw and sliding hip screw constructs, have been studied and found to have similar results with regards to patient outcomes, which has made choosing an optimum fixation strategy difficult. In all of these cases, quality of reduction has been shown to be the most important factor when it comes to creating a favorable environment for fracture healing. Read More

Department of Orthopedic Surgery, Wake Forest Baptist Medical Center, Winston-Salem, NC.

Young femoral neck fractures remain challenging fractures to treat. Reduction has repeatedly been shown to be the single most important determinant of patient outcome, and treating surgeons should do all they can to achieve anatomic reduction because this is an outcome variable within the surgeon's control. Whether an open or closed reduction is performed, we hope to provide the reader with reduction strategies when faced with this difficult fracture pattern. Read More

Since its introduction by Lucien Campeau three decades ago, percutaneous radial artery approach at the forearm has been shown to provide advantages over the femoral approach and has become the standard approach for coronary angiography and intervention. Though infrequent, vascular complications still remain, mainly radial artery occlusion. Therefore, a more distal radial approach at the snuffbox or at the dorsum of hand has been suggested, initially by anethesiologists for perioperative patient monitoring, and more recently by Babunashvili et al.

Implementation of the transradial approach as an alternative vascular access for transcatheter aortic valve replacement guidance: Experience from a high-volume center.

Catheter Cardiovasc Interv 2018 Dec 10. Epub 2018 Dec 10.

Ramsay Générale de Santé, Institut Cardiovasculaire Paris Sud, Massy, Paris, France.

Objective: This study sought to assess the potential benefits of the transradial approach (TRA) as an alternative vascular access to the classical contralateral femoral approach for transcatheter aortic valve replacement (TAVR).

Background: Vascular and bleeding complications in TAVR have gradually decreased owing to operator experience and downsizing of the delivery system. However, about 1/4 of vascular access site complications are related to the transfemoral (TF) secondary access. Read More

Neurologic recovery after deep hypothermic circulatory arrest in rats: A description of a long-term survival model without blood priming.

Artif Organs 2018 Dec 8. Epub 2018 Dec 8.

Department of Cardiopulmonary Bypass, State key laboratory of Cardiovascular Medicine, Fuwai Hospital, National center for Cardiovascular disease, Chinese Academy of Medical science and Peking Union Medical College, Beijing, China.

Brain injury associated with deep hypothermic circulatory arrest (DHCA) has been recognized in patients with congenital heart diseases and those undergoing aortic arch surgeries. However, the preclinical investigation of long-term cerebral injury and recovery mechanisms related to DHCA has been restricted to a satisfactory recovery animal model with a determined recovery time. This study aimed to evaluate the feasibility of a long-term surviving DHCA model without blood priming in rats, in order to investigate the pathophysiology of long-term complications in further studies.
