Effect of Early vs Delayed Surgical Treatment on Motor Recovery in Incomplete Cervical Spinal Cord Injury With Preexisting Cervical Stenosis: A Randomized Clinical Trial.

Importance: The optimal management for acute traumatic cervical spinal cord injury (SCI) is unknown.

Objective: To determine whether early surgical decompression results in better motor recovery than delayed surgical treatment in patients with acute traumatic incomplete cervical SCI associated with preexisting canal stenosis but without bone injury.

Design, Setting, And Participants: This multicenter randomized clinical trial was conducted in 43 tertiary referral centers in Japan from December 2011 through November 2019.

A retro-odontoid pseudotumor treated with fixation and tumor resection by the lateral approach: illustrative case.

Background: A retro-odontoid pseudotumor is not a condition that requires resection. However, pathological diagnosis is required when a tumor such as a meningeal tumor or chordoma is suspected. The authors report a case of a large lesion treated with posterior fixation and tumor resection using a lateral approach.

A nationwide survey on the incidence and characteristics of traumatic spinal cord injury in Japan in 2018.

Study Design: Retrospective epidemiological study.

Objectives: Since the causes and incidences of traumatic spinal cord injury (TSCI) in each country change over time, up-to-date epidemiological studies are required for countermeasures against TSCI. However, no nationwide survey in Japan has been conducted for about 30 years.

Minimally Invasive Cervical Pedicle Screw Fixation (MICEPS) via a Posterolateral Approach.

Cervical pedicle screw (PS) fixation provides great mechanical strength; however, it needs wide soft tissue detachment and has vertebral artery damage risk. Minimally invasive cervical pedicle screw (MICEPS) fixation, a new method for cervical PS fixation through a posterolateral approach, was developed to reduce soft tissue damage and avoid lateral misplacement of screws. Sixty-seven patients with cervical injury underwent MICEPS fixation.

The impact of external fixation on mortality in patients with an unstable pelvic ring fracture: a propensity-matched cohort study.

Aim: There is not adequate evidence to establish whether external fixation (EF) of pelvic fractures leads to a reduced mortality. We used the Japan Trauma Data Bank database to identify isolated unstable pelvic ring fractures to exclude the possibility of blood loss from other injuries, and analyzed the effectiveness of EF on mortality in this group of patients.

Patients And Methods: This was a registry-based comparison of 1163 patients who had been treated for an isolated unstable pelvic ring fracture with (386 patients) or without (777 patients) EF.
