Carl Nicoladoni (1847-1902) studied medicine in Vienna and became Privatdozent in surgery in 1876. He accepted a chair as a Professor of Surgery at the university clinics of Innsbruck (1881) and Graz (1895). Nicoladoni has made significant contributions in the progress of surgery and performed a variety of operations in several surgical disciplines. ⋯ A larger edition printed in 1904 was part of the Bibliotheca Medica, a monumental series of various clinical books published around the beginning of the past century. The second version, a shortened one, with the same title was included in an anthology called Deutsche Chirurgie (German Surgery) and published in 1909. The purpose of this historical article is to discuss Nicoladoni's achievements in the field of scoliosis based on a detailed analysis of his books.

Retrospective case series review. ⋯ Surgical correction was achieved in over half the levels that would have been operated by standard posterior segmental fixation. Bony healing due to the bone-on-bone apposition was achieved uneventfully after apical correction of the spinal curvature in all patients. Use of dual rod instrumentation (Kaneda Anterior Scoliosis System) is fundamental in maintaining the correction of the curvature achieved in the operating room. The preoperative planning technique worked well.

This in vitro biomechanical study was undertaken to quantify the multidirectional intervertebral kinematics following total disc replacement arthroplasty compared to conventional stabilization techniques. ⋯ Total disc arthroplasty serves as the next frontier in the surgical management of discogenic spinal pathology. The SB Charitè restored motion to the level of the intact segment in flexion-extension and lateral bending and increased motion in axial rotation. The anterior annular resection necessary for device implantation and unconstrained design of the prosthesis account for this change in rotation. The normal lumbar flexion-extension axis of rotation is an ellipse rather than a single point. Only disc replacement rather than pedicle instrumentation or BAK interbody instrumentation preserves the kinematic properties and normal mapping of segmental motion at the operative and adjacent intervertebral disc levels.

Comparative Study
Sensory stimulation-guided sacroiliac joint radiofrequency neurotomy: technique based on neuroanatomy of the dorsal sacral plexus.
A retrospective audit and examination of anatomic findings. ⋯ A sensory stimulation-guided approach toward the identification and subsequent radiofrequency thermocoagulation of symptomatic sacral lateral branch nerves appears to offer significant therapeutic advantages over existing therapies for the treatment of chronic sacroiliac joint complex pain.

A retrospective cohort study was conducted. ⋯ In selected patients with neuromuscular scoliosis, even that associated with pelvic obliquity, excellent correction and maintenance correction can be obtained fusing a relatively short segment of the spine with ASF and AI rather than a long construct posteriorly to the pelvis. Maintenance of the correction of the primary curve as well as the pelvic obliquity was maintained over the period of follow-up. This approach for selected patients should be offered as a way of limiting the extend of the surgery, preserving motion segments and maintaining orenhancing functions such as activities of daily living.
