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
