Awake Early Manual Reduction Is Highly Effective for Subaxial Cervical Spine Dislocation.

Introduction: Guidelines published in 2013 recommend early closed reduction for cervical spine dislocation. There are two types of closed reduction: manual reduction and traction. Manual reduction can be performed early.

Minimally invasive surgery technique for unstable pelvic ring fractures with severe vertical shear displacement: A retrospective study.

Background: Unstable pelvic fractures, especially vertical shear fractures, require surgery for correct reduction, rigid fixation, and improved postoperative outcomes. Herein, we assess the effectiveness of our minimally invasive procedure for the management of unstable pelvic fractures.

Hypothesis: We hypothesized that this procedure would be useful for the management of unstable pelvic fractures.

Retro-odontoid pseudotumor with uncommon presentation of cervical spine injury.

Background: We report the first case of retro-odontoid pseudotumor with an isolated symptom of C2-C3 dysesthesia triggered by a traumatic event.

Case Presentation: An 86-year-old man, who was a wood craftsman for more than 50 years, presented to the emergency room with sudden-onset severe posterior head and neck dysesthesia after accidentally falling backward. No neurological impairment of the extremities was noted.

Retrospective high volume comparative study suggests that patients on aspirin could have immediate surgery for hip fractures without significant blood loss.

Purpose: This study aimed to investigate the effects of aspirin on peri-operative hidden blood loss during hip fracture surgery by adjusting for possible factors affecting blood loss using a propensity score matching method.

Methods: We retrospectively collected data from a cohort of isolated hip fracture patients (aged ≥ 65 years)who underwent surgery from January 2010 to December 2019. The study's primary outcome was blood loss from admission to the day after surgery in the aspirin and control groups.

Minimally Invasive Surgery for Unstable Pelvic Ring Fractures: Transiliac Rod and Screw Fixation.

Pelvic fractures occur with high-energy trauma, and the patient's clinical status is unstable. Although a number of surgical methods for unstable pelvic fractures are available, none can achieve strong fixation with minimal invasiveness. We describe a surgical transiliac rod and screw fixation (TIF) procedure that provides minimally invasive fixation using a spinal implant for unstable pelvic ring fractures, and we retrospectively analyzed the procedure's outcomes in 27 patients with type B or C1 fractures (based on the AO/ATO classification system).

Insufficiency and deficiency of vitamin D in elderly patients with fragility fractures of the hip in the Japanese population.

Background: Data of vitamin D sufficiency in Asian patients with osteoporotic fragility hip fractures are limited. This study aimed to obtain data from the Japanese population.

Methods: Patients aged 60 years or older with hip fractures were prospectively enrolled.

Risk factors for lumbosacral plexus palsy related to pelvic fracture.

Study Design: A retrospective study.

Objective: We assessed risk factors for lumbosacral plexus palsy related to pelvic fracture that can be evaluated during the acute injury phase with diagnostics such as computed tomography (CT).

Summary Of Background Data: Many patients with pelvic fracture are in vital shock, with polytrauma and loss of consciousness, making an accurate neurologic examination very difficult in the emergency room.

Cervical cord injury in patients with ankylosed spines: progressive paraplegia in two patients after posterior fusion without decompression.

Study Design: Case report and clinical discussion.

Objective: To describe technical pitfall to treat 2 cervical cord injuries, including dislocations in patients with ankylosed spine due to diffuse idiopathic skeletal hyperostosis (DISH) or ossification of the posterior longitudinal ligament (OPLL).

Summary Of Background Data: DISH and OPLL are disease processes similar in pathology, which can lead to unexpected fractures due to low-energy trauma.

Deep venous thrombosis in patients with acute cervical spinal cord injury in a Japanese population: assessment with Doppler ultrasonography.

Background: Deep venous thrombosis (DVT) and pulmonary thromboembolism are major complications in patients with acute spinal cord injury. The incidence of DVT in patients with a spinal cord injury has ranged from 5% to 26% in several countries; however, the incidence in Japan is unknown.

Methods: We retrospectively assessed 52 patients with acute cervical spinal cord injury.

Clinical accuracy of 3D fluoroscopy-assisted cervical pedicle screw insertion.

Object: Cervical pedicle screw (PS) misplacement leads to injury of the spinal cord, nerve root, and vertebral artery. Recently, several investigators reported on the usefulness of a spinal navigation system that improves the accuracy of PS insertion. In this study, the authors assessed the accuracy of cervical pedicle, lateral mass, and odontoid screw insertions placed using a 3D fluoroscopy navigation system, the Iso-C3D unit.
