Background: In the presence of chin-on-chest deformity of ankylosing spondylitis, positioning for extension osteotomy of the spine is a challenging endeavor. Conventional prone positioning equipment cannot safely accommodate all patients with advanced deformity where the chin brow angle approaches or exceeds 90°. Issues such as inability to accommodate the head and associated equipment while providing operative stability and venous congestion of the head represent significant perioperative risks. The sitting position has been advocated as an alternative but is suboptimal for surgical access and anesthetic care. We present a technical note for a positioning system developed to facilitate extension osteotomy in the prone position.
Methods: A positioning device was designed to accommodate patients with advanced deformity. A series of patients with chin brow angles of up to 89° were positioned using our new system.
Results: We were able to facilitate safe extension osteotomy in the prone position, for procedures lasting up to 14 hours. All our patients were discharged home without significant complication.
Conclusions: Our device is simply constructed and may be easily replicated in other institutions engaging in complex spine surgery. We hope our system provides clinicians with greater freedom to provide optimal perioperative care to their patients.

: EnBloc resections of bone tumors of the spine are very demanding as the target to achieve a tumor-free margin specimen (sometimes impossible due to the extracompartimental tumor extension) is sometimes conflicting with the integrity of neurological functions and spine stability. : The surgical treatment of a huge multi-level chordoma of the thoracic spine with unusual extension is reported. Anteriorly, the tumor widely invaded the mediastinum and displaced the aorta; on the left side, it expanded in the subpleuric region; posteriorly, it was uncommonly distant 13 mm from the posterior wall.

Objective: To report clinical outcomes of skeletally immature dogs with antebrachial deformities secondary to premature closure of the distal radial physis (PCDRP) treated with angular corrections and distraction osteogenesis using circular external skeletal fixation (CESF).
Study Design: Retrospective multi-institutional case series.
Animals: A total of 12 client-owned dogs with premature distal radial physeal closure.
Heterogeneity in the use of osseous risk factors and limited use of relevant patient-reported outcome measurements in studies investigating treatment of patellar dislocation: A scoping review.

Sports Orthopedic Research Center-Copenhagen (SORC-C), Department of Orthopedic Surgery, Copenhagen University Hospital, Amager-Hvidovre, Denmark.
Purpose: The treatment of patellar dislocation is tailored based on the presence or absence of osseous risk factors. The purpose of this scoping review was to investigate whether existing research addresses patient differences by mapping the use of osseous risk factors and patient-reported outcome measures (PROMs) in studies investigating the treatment of patellar dislocation.
Methods: This study was a scoping review conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analysis extension for Scoping Reviews.
Cranial Base Changes After Trans-sutural Distraction Osteogenesis in Growing Patients With Cleft Lip/Palate and Midface Hypoplasia.

Department of Plastic Surgery, Peking University Third Hospital, Beijing, China.
Background: Transesutural distraction osteogenesis (TSDO) is a method of correcting midfacial hypoplasia (MH) secondary to cleft lip and palate (CLP) without osteotomy. However, there has been little research on how the morphology of the cranial base changes postoperatively or whether any correction of the cranial base occurs.
Materials And Methods: This retrospective study included 35 pediatric patients with MH secondary to CLP, who underwent TSDO treatment.
Orthognathic surgery-related condylar resorption in patients with skeletal class III malocclusion versus class III malocclusion: a systematic review and meta-analysis.

School of Dentistry, Complutense University of Madrid, Madrid, 28040, Spain.
Background: Orthodontic-orthognathic treatment is the standard of care for moderate and/or severe skeletal class III (SCIII) malocclusion. Following orthognathic surgery, morphological changes in the temporomandibular joint structures (TMJ) may contribute to condylar resorption (CR).
Objectives: This systematic review aimed to identify the morphological signs of condylar resorption (changes in the condylar head, position, neck, disk, and joint space) following orthognathic surgery in patients with SCIII compared with those with skeletal class II (SCII) malocclusion.
