Risk Factor Analysis for Growth Arrest in Paediatric Physeal Fractures-A Prospective Study.

Fractures through the physis account for 18-30% of all paediatric fractures, leading to growth arrest in up to 5.5% of cases. We have limited knowledge to predict which physeal fractures result in growth arrest and subsequent deformity or limb length discrepancy.

Transfer Validity of Pediatric Supracondylar Humeral Fracture Pin Placement Practice on In-Theater Performance by Orthopedic Trainees Using an Augmented Reality Simulator: Protocol for a Pilot Interventional Cohort Study With a Retrospective Comparator Cohort.

Background: Supracondylar humeral fractures (SCHF) are a common cause of orthopedic morbidity in pediatric populations across the world. The treatment of this fracture is likely one of the first procedures involving x-ray-guided wire insertion that trainee orthopedic surgeons will encounter in their career. Traditional surgical training methods of "see one, do one, teach one" are reliant on the presence of real-world cases and must be conducted within an operative environment.

Inter-rater and Intra-rater Reliability in the Radiographic Diagnosis of Growth Arrest in Paediatric Physeal Fractures.

Background: Fractures through the physis account for 18-30% of paediatric fractures and can lead to growth arrest in 5-10% of these cases. Long-term radiographic follow-up is usually necessary to monitor for signs of growth arrest at the affected physis. Given plain radiographs of a physeal fracture obtained throughout patient follow-up, different surgeons may hold different opinions about whether or not early growth arrest has occurred despite using identical radiographs to guide decision-making.

Developmental Dysplasia of the Hip: An Examination of Care Practices of Orthopaedic Surgeons in India.

Background: We evaluated screening, referral and treatment practices for developmental dysplasia of the hip (DDH) in India by surveying Orthopaedic surgeons who treat patients with DDH. The survey assessed the timing of DDH presentation, resource availability, and current state of screening and diagnosis, which would help in the development of a DDH care pathway for India.

Methods: An online survey was distributed to Orthopaedic surgeons practicing in India via email and administered onsite to those attending the annual conference of the Pediatric Orthopaedic Society of India in 2019.

Does a titanium-coated polyethylene press-fit cup give reliable midterm results?

Background: Uncemented acetabular components have demonstrated low revision rates and high patient satisfaction but with concerns regarding increased costs compared with monoblock cups. Some newer lower-cost uncemented monoblock options have become available in the last decade, but limited data are available on their performance.

Questions/purposes: (1) Does an uncemented, titanium-backed all-polyethylene acetabular cup provide reliable fixation? (2) What is the frequency and what are the causes for revision with this cup?

Methods: Between 2004 and 2008, we elected to use an uncemented, titanium-backed all-polyethylene acetabular cup in older patients with limited physical demands.

The relationship between the American Society Of Anesthesiologists physical rating and outcome following total hip and knee arthroplasty: an analysis of theNew Zealand Joint Registry.

Background: The purpose of this study was to review the results of the first four years of use of the American Society of Anesthesiologists (ASA) physical status rating system in the New Zealand Joint Registry. Our hypothesis was that patients with a higher ASA score would have an increased mortality rate, an increased early revision arthroplasty rate, and poorer clinical outcomes at six months after total hip or knee arthroplasty.

Methods: We prospectively evaluated the preoperative ASA classes for all patients in the registry who underwent primary total hip or knee arthroplasty from 2005 to 2008 with regard to the six-month mortality rate and the Oxford Hip and Knee Scores at six months.

Bilateral total joint arthroplasty: the early results from the New Zealand National Joint Registry.

This study evaluated the mortality rate, major complications, and early outcomes of single anesthetic bilateral total hip and knee arthroplasty compared with unilateral and staged procedures. A total of 37,828 total hip and knee arthroplasties were evaluated with 6-month Oxford 12 scores. Major complications and mortality rates were recorded.
