Background: This study aimed to evaluate and analyze the prevalence and radiological characteristics of the fabella in the Turkish population, detecting differences between genders by examining magnetic resonance imaging (MRI) images of subjects.

Methods: A total number of 504 patients aged >18 years who were admitted to the orthopedics and traumatology clinic between November 2018 and October 2020 were included in this retrospective cross-sectional study. Bilateral MRI images that were taken from each patient were randomly selected.

The Terrible Triad of the Elbow Accompanied by Capitellum and Humerus Shaft Fracture: A Rare Case Report.

The terrible triad of the elbow consists of radial head fracture and coronoid process fracture in addition to posterior dislocation of the elbow. It indicates high-risk complications such as instability, malunion, nonunion, and proximal radioulnar synostosis. We describe a rare case that was admitted to the emergency service with a terrible triad of the elbow with additional capitellum fracture, lateral collateral ligament (LCL) injury, and ipsilateral humeral shaft fracture.

Anterior-to-Posterior Epidural Migration of a Lumbar Disc Herniation at L1-L2: A Case Report.

Protruded disc fragments that penetrate the posterior longitudinal ligament (PLL) migrate rostral or caudal in the vertical plane, some laterally in the horizontal plane, or into the foramina involving the anterior aspect of the spinal canal. Often, there is migration to the ventral epidural space. However, posterior epidural migration of a lumbar disc herniation (PEMLDH) is a rare phenomenon that makes the differential diagnosis challenging.

Resolution of the lumbosacral fractional curve and evaluation of the risk for adding on in 101 patients with posterior correction of Lenke 3, 4, and 6 curves.

Objective: In double and triple major adolescent idiopathic scoliosis curves it is still controversial whether the lowest instrumented vertebra (LIV) should be L3 or L4. Too short a fusion can impede postoperative distal curve compensation and promote adding on (AON). Longer fusions lower the chance of compensation by alignment changes of the lumbosacral curve (LSC).

The Importance of Lumbar Curve Flexibility and Apical Vertebral Rotation for the Prediction of Spontaneous Lumbar Curve Correction in Selective Thoracic Fusion for Lenke Type 1 and 2 C Curves: Retrospective Cohort Study with a Mean Follow-Up of More than 10 years.

Study Design: Retrospective analysis of a prospectively collected data.

Objective: Lumbar flexibility(LF) is generally defined with preoperative side bending films;it is not clear what percentage of LF predicts the spontaneous lumbar curve correction (SLCC) at long term follow up. Aim of this study was to find out cut-off value of preoperative LF,apical vertebra rotation(AVR) and apical vertebral translation(AVT);which may predict more than 50%SLCC.

Clinical, radiological and HRQoL outcomes after selective thoracic fusion with minimum 15-year follow-up.

Introduction: The purpose of the study was to provide a 15-year natural history evaluation of the radiographic appearance of uninstrumented compensatory lumbar curves in patients who had undergone selective thoracic fusion (STF) for scoliosis, measure any changes in health-related quality of life scores (HRQoL) and compare them with controls matched for age, gender and body-mass index (BMI).

Methods: STF group included 43 female adolescent idiopathic scoliosis (AIS) patients who underwent STF with mean age 33(27-42) years and a mean follow-up of 18.7 (15-28) years, mean BMI 22(18-29).

``Sandwich technique" with dual strut allograft in surgical treatment of femoral nonunion.

Objective: The treatment of femoral nonunion is challenging for both the surgeon and the patient. Strut allografts increase the bone stock, enhance fracture healing and increase stability by acting as a biological plate. In this study, we aimed to report the results of the sandwich technique with two-strut allograft in the treatment of oligotrophic or atrophic femoral nonunions.

Effect of cementing on pulmonary arterial pressure in vertebroplasty: A comparison of two techniques.

Background: Increase in intraosseous pressure and displacement of bone marrow contents leading to fat embolism and hypotension during cement injection in vertebroplasty (VP). We aimed to compare the effect of low and high viscosity cements during VP on pulmonary arterial pressure (PAP) with different cannula.

Materials And Methods: Fifty-two patients having multilevel VP due to osteoporotic vertebral compression fractures were randomly treated either by a high viscosity cement (group A, = 27 patients) and 2.

Is It Difficult to Dominate the Coronal and Sagittal Planes in Convex Rod Rotation Technique? The Effect of the Ucar Convex Rod Rotation Technique.

Study Design: Prospective multicenter study.

Objective: To analyze the effect of the Ucar convex rod rotation technique on coronal and sagittal correction in the treatment of Lenke type I adolescent idiopathic scoliosis.

Summary Of Background Data: Various common curve correction techniques were used in scoliosis.

Recessive MYF5 Mutations Cause External Ophthalmoplegia, Rib, and Vertebral Anomalies.

MYF5 is member of the Myc-like basic helix-loop-helix transcription factor family and, in cooperation with other myogenic regulatory factors MYOD and MYF5, is a key regulator of early stages of myogenesis. Here, we report three consanguineous families with biallelic homozygous loss-of-function mutations in MYF5 who define a clinical disorder characterized by congenital ophthalmoplegia with scoliosis and vertebral and rib anomalies. The clinical phenotype overlaps strikingly with that reported in several Myf5 knockout mouse models.

Pulmonary cement embolism following cement-augmented fenestrated pedicle screw fixation in adult spinal deformity patients with severe osteoporosis (analysis of 2978 fenestrated screws).

Introduction: There is very limited information about pulmonary cement embolism (PCE) following cement-augmented fenestrated pedicle screw (CAFPS) fixation in the literature. The aim of this study to report the incidence of PCE following CAFPS fixation in adult deformity patients with severe osteoporosis and to identify risk factors such as; the number of levels, number of screws, and the cement volume used.

Methods: 281 patients (204F, 77M) in whom CAFPS fixation was used during deformity surgery were included.

The effect of mechanical aspiration of the vertebral body on pulmonary arterial pressure before cement injection in the vertebroplasty procedure.

Purpose: The aim of this study is to compare the efficacy of the mechanical aspiration technique just prior to cement application in the standard vertebroplasty (VP).

Methods: Forty patients were included in the study. In group A, mechanical aspiration of the cavity was done just before the cement injection and in group B aspiration of vertebral body did not perform, VP was done with the same size cannula, same injection force, same injection speed and same cement viscosity.

Cervicothoracic spine duplication: a 10-year follow up of a neurological intact boy.

Purpose: Spine duplication is a very rare condition with the literature being composed of only case reports. All previously reported cases were thoracolumbar spine duplications. Here, we report cervicothoracic spine duplication in a neurological intact male.

Anterior Femoral Bow and Possible Effect on the Stifle Joint: A Comparison between Humans and Dogs.

The aim of the study was to compare the anterior bow of the femur between dogs and humans in terms of the possible impact on the stifle joint. The femoral radiographs obtained retrospectively were used to determine the angles and positions of the anterior bow in both dogs (n = 135) and humans (n = 57). Descriptive statistics and Pearson's correlation analysis were used for the statistical analyses of the variables.

Does It Make a Difference to Stop Fusion at L3 Versus L4 in Terms of Disc and Facet Joint Degeneration: An MRI Study With Minimum 5 Years Follow-up.

Objectives: To compare the functional outcomes of patients with idiopathic scoliosis who had surgical correction and fusion with all pedicle screw construct down to L3 or L4 and to evaluate whether saving a mobile lumbar motion segment distally would demonstrate any difference in terms of disc degeneration (DD) and facet joint degeneration (FJD) after minimum 5 years follow-up.

Summary Of Background Data: Selection of lowest instrumented vertebra (LIV) is often difficult when lumbar curve was included into the fusion (L3 vs L4). Saving L4 is believed to be beneficial for preserving motion and preventing degeneration of unfused lumbar spine.

Does pedicle screw fixation under age 5 cause spinal canal narrowing? A CT study with minimum 5 years follow-up.

Purpose: The aim of this retrospective study was to evaluate the changes in the vertebral body and spinal canal area in a group of patients who had pedicle screw fixation under age 5 for the treatment of congenital spinal deformity at least 5 year follow-up.

Methods: 11 patients who had been operated due to spinal deformity under age 5 with who had a CT examination at least 5 years after the initial operation were included in the study. All patients underwent hemivertebrectomy and transpedicular fixation procedures at an average age of 3.

Selective Thoracic Fusion Provides Similar Health-Related Quality of Life but Can Cause More Lumbar Disc and Facet Joint Degeneration: A Comparison of Adolescent Idiopathic Scoliosis Patients With Normal Population 10 Years After Surgery.

Objectives: To evaluate the long-term behavior of the lumbar curve in patients with adolescent idiopathic scoliosis treated with selective thoracic fusion and to assess the clinical and radiologic outcomes in this fusion group compared with an age- and gender-matched group.

Summary Of Background Data: Selective thoracic fusion for the treatment of adolescent idiopathic scoliosis (AIS) preserves lumbar motion segments but leaves a residual deformity. By avoiding fusion of the lumbar spine, a greater mobility may be preserved, which may be an advantage in long-term follow-up in terms of degenerative changes in unfused segments.

Surgical treatment of cervical unilateral locked facet in a 9-year-old boy: A case report.

Most of the cervical spine injuries in the pediatric population are typically seen in the upper cervical region. Unilateral cervical facet dislocation (UFD) in subaxial region is a rare injury in pediatric population. In this paper, a rare case of delayed locked UFD in a 9-year-old boy with rare injury mechanism treated surgically is reported.

Report from the 2014 Scoliosis Research Society Travelling Fellowship.

The Scoliosis Research Society traveling fellowship was conceptualized in 1970, repeated in 1972, and, after a pause, restarted in 1993. International traveling fellows visiting North America first commenced in 2000 and have since alternated annually with the North American fellows. Although a senior fellow had always traveled with them, in 2012 the first senior international fellow traveled with the group.

Motor evoked potentials in 43 high risk spine deformities.

Introduction: Correction of pediatric spine deformities is challenging surgical procedures. This fragile group of patients has many risk factors, therefore prevention of most fearing complication-paraplegia is extremely important. Monitoring of transmission of neurophysiological impulses through motor and sensor pathways of spinal cord gives us an insight into cord's function, and predicts postoperative neurological status.

Apical and intermediate anchors without fusion improve Cobb angle and thoracic kyphosis in early-onset scoliosis.

Background: The main goal of treatment in early-onset scoliosis is to obtain and maintain curve correction while simultaneously preserving spinal, trunk, and lung growth. This study introduces a new surgical strategy, called the modified growing rod technique, which allows spinal growth and lung development while controlling the main deformity with apical and intermediate anchors without fusion. The use of intraoperative traction at the initial procedure enables spontaneous correction of the deformity and decreases the need for forceful correction maneuvers on the immature spine and prevents possible implant failures.

Pneumomediastinum, subcutaneous emphysema, and tracheal tear in the early postoperative period of spinal surgery in a paraplegic achondroplastic dwarf.

Achondroplasia was first described in 1878 and is the most common form of human skeletal dysplasia. Spinal manifestations include thoracolumbar kyphosis, foramen magnum, and spinal stenosis. Progressive kyphosis can result in spinal cord compression and paraplegia due to the reduced size of spinal canal.

Traction X-ray under general anesthesia helps to save motion segment in treatment of Lenke type 3C and 6C curves.

Background Context: In patients with structural lumbar curves, several studies have shown the advantages of stopping fusion at L3 and saving L4. However, fusing the L4 may still be deemed necessary in a significant number of patients with structural lumbar curves (ie, Lenke types 3 and 6) when fusion levels are selected by using traditional flexibility X-ray (TXR) methods such as supine side bends and traction.

Purpose: The aim of this retrospective study was to evaluate the effectiveness of the traction X-ray under general anesthesia (TrUGA) method in saving the L4 in patients with Lenke types 3C and 6C curves.
