Spinal sagittal alignment and postoperative adding-on in patients with adolescent idiopathic scoliosis after surgery.

Introduction: Surgery for patients with adolescent idiopathic scoliosis (AIS) may change spinal sagittal alignment, and postoperative adding-on may affect spinal sagittal balance after reconstruction. This study was to investigate the effect of surgery on spinal sagittal alignment and the relationship between postoperative adding-on and spinal sagittal balance in patients with AIS.

Hypothesis: The hypothesis of this study was that the effect of surgery on AIS was associated with recovery of the spinal sagittal plane and that presence of postoperative adding-on might affect the spinal sagittal balance.

Sagittal morphology of the cervical spine in adolescent idiopathic scoliosis: a retrospective case-control study.

Background: To investigate the relationship between sagittal alignment and coronal deformity in patients with adolescent idiopathic scoliosis (AIS) through analysis of the spinal imaging data.

Methods: Four hundred and fifty-four AIS patients who underwent anteroposterior and lateral radiography of the while spine were enrolled, and the spinal parameters of Cobb angle, cervical lordosis, C1-C2 angle, T1 slope, thoracic kyphosis, lumbar lordosis, sacral slope, pelvic tilt (PT), pelvic incidence (PI), cervical sagittal vertical axis (SVA), and spinal SVA were analyzed.

Results: The patients were divided into two groups according to the size of the Cobb angle: group A (Cobb angle ≤45°, n=414) and group B (Cobb angle >45°, n=40).

Intramedullary Well-differentiated Osteosarcoma: Imaging and Pathologic Findings in 17 Patients.

Background: Intramedullary well-differentiated osteosarcoma (IMWDOS) is rare and may easily be misdiagnosed.

Objective: This study aimed at investigating the clinical, imaging, and pathological features of IMWDOS for correct diagnosis.

Materials And Methods: Seventeen patients with IMWDOS were enrolled, and their clinical, imaging, and pathological data were analyzed.

Value of the 45-degree reverse oblique view of the carpal palm in diagnosing scaphoid waist fractures.

Objectives: To investigate the value of 45° reverse oblique view of the carpal palm in diagnosing scaphoid waist fracture and displacement.

Methods: Eighty-four patients with wrist injury and plain radiography including posteroanterior, lateral, Stecher, and 45° reverse oblique view of the wrist were analyzed for the detection rate in diagnosing scaphoid fractures and displacement. The degree of difficulty in the four views for detecting the scaphoid waist fracture and displacement was rated on a five-grade Likert scale.

Lower Tibial Shaft Spiral Fracture Concurrent with Distal Tibial Triplane Fracture.

Background: The clinical and imaging features of lower tibial shaft spiral fracture concurrent with distal tibial triplane fracture are not clear.

Introduction: This study was conducted to investigate these features for correct diagnosis, treatment and prevention of possible premature physeal arrest or angular deformation.

Methods: Patients with lower tibial shaft spiral fracture concurrent with distal tibial triplane fracture were enrolled, and the clinical, imaging, treatment and follow-up data were analyzed.

Dedifferentiated chondrsarcoma: a clinicopathologic analysis of 25 cases.

Background: To investigate the clinical, imaging and pathological features of dedifferentiated chondrosarcoma for better diagnosis.

Methods: Patients who had been confirmed to have dedifferentiated chondrosarcoma were enrolled in this study and analyzed in the clinical, imaging and pathological data.

Results: Twenty-five patients had pathologically confirmed dedifferentiated chondrosarcoma including 15 males and 10 females with an age range of 24-74 (median 58, interquartile range 49-65).

Imaging features of hemangioma in long tubular bones.

Background: To investigate the imaging features of hemangiomas in long tabular bones for better diagnosis.

Methods: Twenty-four patients with long bone hemangiomas confirmed by pathology were enrolled. Nineteen patients had plain radiography, fourteen patients had computed tomography (CT) and eleven had magnetic resonance imaging (MRI).

Value of modified axial review radiograph in diagnosing calcaneal fractures.

To investigate the value of modified calcaneal axial radiograph-the horizontal calcaneal axial radiograph in diagnosing calcaneal fractures, patients who had acute calcaneal fractures or internal fixation were enrolled, and three groups were established, including the acute fracture group (n = 20), the internal fixation group (n = 20), and the healthy control group (n = 20). All the subjects had regular and modified calcaneal axial radiograph for comparison. In analysis of the results, all volunteers could have ankle dorsiflexion at different degrees.

Radiographic analysis of adult ankle fractures using combined Danis-Weber and Lauge-Hansen classification systems.

This study was to analyze ankle fractures for determining the epidemiology, types, distribution, possible mechanisms and diagnosis precision. Between January 2013 and December 2017, all Chinese patients older than 16 years of age with ankle fractures excluding old ankle fractures and pathological fractures in a tertiary care hospital were analyzed by using the Danis-Weber and Lauge-Hansen classification systems. Among 3952 patients with ankle fractures, 1225 fractures (31%) were Danis-Weber type A, 1640 (42%) were type B, 751 (19%) were type C, and 336 (9%) were perpendicular compression fracture.

Femoral pseudotumor secondary to injury in a patient with idiopathic thrombocytopenic purpura: Case report.

Rationale: Idiopathic thrombocytopenic purpura (ITP) is the condition of having a low platelet count of unknown causes and is a poorly understood acquired hemorrhagic disease involving destruction of platelets in the reticuloendothelial system induced by antiplatelet antibodies. Patients with ITP can have traumatic intra-articular, intraosseous or soft tissue hemorrhage which may present as a rare intraosseous pseudotumor on medical imaging.

Patient Concerns: A 30-year old male patient had complaint of pain in the right leg for 1 year.
