Objective: This study was designed to define fracture lines and comminution zones in OTA/AO 23C3 distal radius fractures from axial computed tomography (CT) images that would influence surgical planning, development of new classifications, and possible implant designs. Methods: Thirty-four consecutive OTA/AO 23C3 fractures treated by a single surgeon between January 2014 and December 2014 were analyzed. For each fracture, maps of the fracture lines and zones of comminution were drawn. Each map was digitized and graphically superimposed to create a compilation of fracture lines and zones of comminution. Based on this compilation, major and minor fracture lines were identified and fracture patterns were defined. Results: All major fracture lines were distributed in the central region of the radius distal articular surface. There is a recurrent fracture pattern with a comminution zone including the scaphoid and lunate fossa; Lister's tubercle; and ulnar, volar, and radial zones. Conclusion: It is important for the practicing surgeon to understand these four main fragments. Knowledge of this constant pattern should influence the development of new classifications and possible implant designs.

Maternal diabetes mellitus, hypoxia, vitamin deficiencies, and anticonvulsant medication use have been associated with CS (9). Development of the spinal cord and organs of mesodermal origin is closely related to development of the vertebral column (1). As a result, CS is often associated with anomalies of the spinal cord, cardiovascular system, and genitourinary system (12). Previously, the incidences of intraspinal and other organ system pathologies associated with CS were reported █ INTRODUCTION C ongenital scoliosis (CS) is characterized by a spinal curvature secondary to congenital vertebral malformations. Deformity of the spine secondary to failure of normal vertebral development at 4-6 weeks of gestation is an accepted criterion (16). A multifactorial etiology of scoliosis is accepted (2,10,15). The genetic factors associated with CS remain largely unknown (8). However, environmental factors are proven to have a strong relationship with CS (1,8,9,14,23). AIM: To report the incidence and interrelationship of concomitant anomalies in congenital scoliosis (CS) patients. MATERIAL and METHODS: Whole-spine computed tomography and magnetic resonance imaging (MRI) examination, echocardiography, and renal ultrasonography (USG) evaluations of 231 patients with CS were reviewed. Additionally, intraspinal pathologies and structural cardiac and renal anomalies were recorded. RESULTS: The incidence of intraspinal pathology was 53.7%. Echocardiography was performed in 140 of 231 patients, and congenital heart disease was detected in 38 patients. Renal USG was performed in 133 of 231 patients, and a renal disease was detected in 37 patients. In 133 patients, spinal MRI, echocardiography, and renal USG were performed. In 22 of 67 (32.8%) patients with an intraspinal anomaly, an additional cardiac anomaly was detected. In 27 of 67 (40.3%) patients with an intraspinal anomaly, an additional renal anomaly was detected. In 47.3% of patients with a cardiac anomaly, an additional renal anomaly was detected. In 15 of 133 patients (11.2%) intraspinal, cardiac, and renal anomalies were identified. CONCLUSION: Surgeons should evaluate additional anomalies in CS if patients report having a congenital anomaly. Because cardiac and renal anomalies increase intra-and postoperative complication risks, a careful and comprehensive preoperative evaluation is needed.

Study DesignRetrospective study.PurposeTo identify the incidence of congenital cardiac abnormalities in patients who had scoliosis and underwent surgical treatment for scoliosis.Overview of LiteratureCongenital and idiopathic scoliosis (IS) are associated with cardiac abnormalities. We sought to establish and compare the incidence of congenital cardiac abnormalities in patients with idiopathic and congenital scoliosis (CS) who underwent surgical treatment for scoliosis.MethodsNinety consecutive scoliosis patients, who underwent surgical correction of scoliosis, were classified as CS (55 patients, 28 female [51%]) and IS (35 patients, 21 female [60%]). The complete data of the patients, including medical records, plain radiograph and transthoracic echocardiography were retrospectively assessed.ResultsWe found that mitral valve prolapse was the most common cardiac abnormality in both patients with IS (nine patients, 26%) and CS (13 patients, 24%). Other congenital cardiac abnormalities were atrial septal aneurysm (23% of IS patients, 18% of CS patients), pulmonary insufficiency (20% of IS patients, 4% of CS patients), aortic insufficiency (17% of IS patients), atrial septal defect (11% of IS patients, 13% of CS patients), patent foramen ovale (15% of CS patients), dextrocardia (4% of CS patients), bicuspid aortic valve (3% of IS patients), aortic stenosis (2% of CS patients), ventricular septal defect (2% of CS patients), and cardiomyopathy (2% of CS patients).ConclusionsWe determined the increased incidence of congenital cardiac abnormalities among patients with congenital and IS. Mitral valve prolapse appeared to be the most prevalent congenital cardiac abnormality in both groups.

Introduction: No significant regression has been reported in revision total hip arthroplasty (THA) rates despite substantial progress in implant technologies and surgical techniques. It is critical to investigate how patient demographics, THA indications, surgical techniques, types of implants, and other factors influence the frequency of early and late revision surgery. The main purpose of the present study was to evaluate the clinical characteristics and 10-year survival rates of revision hip arthroplasties among revision time groups. Material and methods: The clinical data of 396 patients who underwent revision hip arthroplasty between 2005 and 2011 were evaluated in this multi-centre study. Patients were assigned to one of four revision time groups based on the interval between the index hip arthroplasty and the revision surgery (< 2, 2-5, 5-10, and > 10 years). Results: There were significant differences among revision time groups in terms of aetiology for primary hip arthroplasty, indications for revision hip arthroplasty, and types of revision procedures. Patients with hip dysplasia more frequently received revision hip arthroplasty within two years in contrast to those with osteoarthritis. Revision hip arthroplasties due to periprosthetic infection and instability were conducted earlier compared to aseptic loosening. The overall 10-year survival rate of revision hip arthroplasty was 83.2%, and it was highest for the very early revisions (< 2 years). Conclusions: According to our results, early revision hip arthroplasty was found to be mostly dependent on surgery-related factors rather than demographic factors. On the other hand, we observed that survival rates of very early revision hip arthroplasties are higher than late revision hip arthroplasties.
