INTRODUCTION: Pelvic apophyseal avulsion can limit young athletes' performance for months and may result in permanent disability. Nonoperative treatment is most commonly preferred, while surgical management with reduction and fixation is reserved for selected cases. Our aim was to evaluate outcomes of operative management of pelvic apophyseal avulsions in a series of adolescents and young adult athletes. MATERIALS AND METHODS: Operative room registries and medical records were reviewed to identify patients who received surgical treatment for pelvic apophyseal avulsions who were younger than 24 years and with a minimum of 12 month follow-up...

Background: Segmental rolling has been utilized as an assessment and intervention tool to identify and affect dysfunction of the upper quarter, core, and lower quarter. One theory to explain dysfunctional segmental rolling is a lack of segmental spinal control / stabilization. Faulty muscle firing sequencing has been related to poor spinal stability, however to date, no assessment tool exists to evaluate a patient's motor coordination of local and global musculature. Purpose: The purpose of this study was to assess the temporal sequence of lumbar multifidus activation associated with anterior deltoid activation, and to determine if faulty sequencing was associated with the inability to segmentally roll in subjects without mobility restrictions...

Pelvic tilt is an essential parameter in spinal deformity surgery and in acetabular positioning for total hip arthroplasty. However, the measurement of tilt varies between the hip and spine literature. Hip surgeons measure the anterior pelvic plane tilt, whereas spine surgeons measure the spinopelvic tilt. This study uses stereoradiography (EOS imaging SA, Paris, France) to assess the relationship and the inter-observer and intra-observer reliability of measuring these two common references for pelvic tilt...

Interbody fusion with posterior instrumentation is a common method for treating lumbar degenerative disc diseases. However, the high rigidity of the fusion construct may produce abnormal stresses at the adjacent segment and lead to adjacent segment degeneration (ASD). As such, biodegradable implants are becoming more popular for use in orthopaedic surgery. These implants offer sufficient stability for fusion but at a reduced stiffness. Tailored to degrade over a specific timeframe, biodegradable implants could potentially mitigate the drawbacks of conventional stiff constructs and reduce the loading on adjacent segments...

Background  Most existing objective surgical motion analysis schemes are limited to structured surgical tasks or recognition of motion patterns for certain categories of surgeries. Analyzing instrument motion data with respect to anatomical structures can break the limit, and an anatomical region segmentation algorithm is required for the analysis. Methods  An atlas was generated by manually segmenting the skull base into nine regions, including left/right anterior/posterior ethmoid sinuses, frontal sinus, left and right maxillary sinuses, nasal airway, and sphenoid sinus...

BACKGROUND: Clinical and quality of life (QOL) outcomes vary depending on the patient's demographics, comorbidities, presenting symptoms, pathology, and surgical treatment used. While there have been individual predictors identified, no comprehensive method incorporates a patient's complex clinical presentation to predict a specific individual postoperative outcome. OBJECTIVE: To create tool that predicts patient-specific outcomes among those undergoing cervical spine surgery...

While cervical lordosis alteration is not uncommon after anterior cervical arthrodesis, its influence on radiological adjacent segment pathology (RASP) is still unclear. Biomechanical changes induced by arthrodesis may contribute to ASP onset. To investigate the correlation between cervical lordosis decrease and RASP onset after anterior cervical corpectomy and fusion (ACCF) and to determine its biomechanical effect on adjacent segments after surgery, 80 CSM patients treated with ACCF were retrospectively studied, and a baseline finite element model of the cervical spine as well as post-operation models with normal and decreased lordosis were established and validated...

PURPOSE: Posterior-anterior spondylodesis is often used to stabilise the spine in various pathologies. The anterior procedure is often conducted via thoracoscopy. It remains unclear whether the anterior procedure should be conducted immediately after posterior instrumentation or only after the patient has convalesced. This retrospective study compared one-stage and two-stage posterior-anterior fusion surgery with a thoracoscopic anterior approach in terms of perioperative safety and morbidity...

The treatment of nasomaxillary hypoplasia is challenging. The phenotype of Binder "syndrome" includes the following: midfacial hypoplasia, class III malocclusion, small or absent anterior nasal spine, flattened nose, horizontal nostrils, short columella, acute nasolabial angle, and a flat frontonasal angle. A staged approach is used, with orthognathic surgery to achieve vertical maxillary length and sagittal advancement, followed by rhinoplasty aimed to increase nasal tip projection, rotation, and columellar length...

Anterior cervical spine procedures have been associated with satisfactory outcomes. However, the occurrence of troublesome complications, although uncommon, needs to be taken into consideration. The purpose of our study was to assess the actual incidence of anterior cervical spine procedure-associated complications and identify any predisposing factors. A total of 114 patients undergoing anterior cervical procedures over a 6-year period were included in our retrospective, case-control study. The diagnosis was cervical radiculopathy, and/or myelopathy due to degenerative disc disease, cervical spondylosis, or traumatic cervical spine injury...

STUDY DESIGN: a retrospective study. OBJECTIVES: Anterior cervical fusion surgery is widely used procedure in cervical spondylosis. When considering the blood re-infusion strategies of cervical fusion surgery, the amount of blood loss is one of the key element. We usually calculate the blood loss according to the surgical bleeding plus the postoperative drainage; however, it ignored the possibility that there may be a partly amount of hidden blood loss. METHODS: We performed a retrospective study to determine the risk factors for HBL in patients underwent anterior cervical fusion surgery for degenerative spine from 2013 to 2016...

Cervical spine injuries are the most common spine injuries in the pediatric population. The authors present the youngest known patient who underwent cervical spine fusion to repair birth trauma-induced cervical fracture dislocation, resulting in spondyloptosis and spinal cord injury. A 2-week-old boy was found to have spondyloptosis and spinal cord injury after concerns arose from reduced movement of the extremities. The patient's birth was complicated by undiagnosed abdominal dystocia, which led to cervical distraction injury...
