To investigation of the outcomes of indirect posterior decompression with corrective fusion for myelopathy associated with thoracic ossification of the longitudinal ligament, and prognostic factors. Conservative treatment for myelopathy associated with thoracic ossification of the longitudinal ligament (OPLL) is mostly ineffective, and treatment is necessary. However, many authors have reported poor surgical outcomes, and no standard surgical procedure has been established. ⋯ We consider that additional application of anterior decompressive fusion is preferable when improvement of symptoms occurs not satisfactory after indirect posterior decompression with corrective fusion using instruments. Intraoperative spinal cord monitoring of CMAP demonstrated that the spinal cord was already impaired during the laminectomy via the posterior approach. Concomitant intraoperative monitoring of CMAP to avoid impairment of the vulnerable spinal cord and corrective posterior spinal fusion with indirect spinal cord decompression is recommendable as a method capable of preventing postoperative neurological aggravation.

The aim of this study is to examine the predictive value of ultrasound diagnostics for the assessment of traumatic lesions of the posterior ligament complex (PLC) in burst fractures of the thoracolumbar spine. This was a prospective validating cohort study. Judgment about instability and treatment of burst fractures depends on the condition of the PLC. ⋯ As hypothesized the obtained predictive value using ultrasound correlates closely with intraoperative findings. Anyway MRI still seems to be the superior diagnostic method for examining the PLC. However, ultrasound can be considered to be an adequate alternative method in cases with contraindications for MRI such as ferromagnetic side effects, claustrophobia, availability or emergency diagnostics in multiple injuries.

This is a case report of a 15-month-old patient with osteogenesis imperfecta (OI) who sustained atlanto-axial dislocation. Our objective is to report a unique case of traumatic atlanto-axial subluxation in a child with osteogenesis imperfecta associated with bilateral femoral fractures. The management is discussed. ⋯ The child has had a successful outcome. She is asymptomatic with a full range of movement at the atlanto-axial joints at 9 months. In conclusion, this paper records our management of this rare problem.

The objective of the study was to evaluate the breathing pattern in patients with chronic non-specific low back pain (LBP) and in healthy subjects, both at rest and during motor control tests. Ten healthy subjects and ten patients with chronic LBP participated at this case-control study. The breathing pattern was evaluated at rest (standing and supine position during both relaxed breathing and deep breathing) and while performing clinical motor control tests, i.e. bent knee fall out and active straight leg raise. ⋯ At rest, no significant differences were found between the breathing pattern of patients and healthy subjects (P > 0.05). In contrast, significantly more altered breathing patterns were observed in chronic LBP-patients during motor control tests (P = 0.01). Changes in breathing pattern during motor control tests were not related to pain severity (P > 0.01), but were related to motor control dysfunction (P = 0.01).

The purpose of this study was to develop a quantitative skin impedance test that could be used to diagnose spinal cord injury (SCI) if any, especially in unconscious and/or non-cooperative SCI patients. To achieve this goal, initially skin impedance of the sensory key points of the dermatomes (between C3 and S1 bilaterally) was measured in 15 traumatic SCI patients (13 paraplegics and 2 tetraplegics) and 15 control subjects. ⋯ It could classify traumatic SCI patients with a success rate of 73%. By assessing the experimental protocols and the validation results, the proposed method seemed to be a simple, objective, quantitative, non-invasive and non-expensive way of assessing SCI in such patients.
