Bone Preservation in Femoral Intercondylar Box Cut - A Comparative Study between Older and Newer Generation Implants.

Introduction: This study was conducted to compare the quantity of intercondylar bone removed during femoral box osteotomy for implantation of three contemporary newer generation posterior stabilized (PS) total knee arthroplasty designs Attune PS (DePuy), Anthem (Smith and Nephews), and NexGen Legacy (Zimmer) with the older version from the same manufacturers.

Materials And Methods: We compared the maximum volumetric bone resection required for the housing of the PS mechanism of these six designs. Bone removal by each PS box cutting jig was three-dimensionally measured.

Challenges to the orthopedic resident workforce during the first wave of COVID-19 pandemic: Lessons learnt from a global cross-sectional survey.

Background: The COVID-19 pandemic has caused unprecedented concerns on the safety, well-being, quality of life(QOL), and training of the orthopedic resident physician workforce worldwide. Although orthopedic residency programs across the globe have attempted to redefine resident roles, educational priorities, and teaching methods, the global orthopedic residents' perspective with regards to their safety, well-being, QOL, and training, taking into account regional variances remains unknown.

Methods: A 56-item-questionnaire-based cross-sectional survey was conducted online during the COVID-19 pandemic involving 1193 orthopedic residents from 29 countries across six geographical regions to investigate the impact of the COVID-19 pandemic on the well-being, safety, and training of orthopedic residents at a global level, as well as to analyze the challenges confronted by orthopedic residency programs around the world to safeguard and train their resident workforce during this period.

Delayed unrelated presentation of a lumbar burst fracture consequent to a remote episode of a single convulsive seizure: A diagnostic challenge.

Unlabelled: Non-traumatic vertebral fractures occurring as a sole consequence of the violent muscle forces generated during the first episode of a GTCS(generalized tonic clonic seizure) in a previously healthy non-epileptic individual are very rare. Being clinically asymptomatic they are easily overseen at the time of initial presentation due to their rarity of occurrence and the presence of potentially distracting factors in the post-ictal phase. We present a 52-year-old healthy non-epileptic male who presented with unrelenting back pain and neurodeficit secondary to a four-month-old unstable burst fracture of the first lumbar vertebra sustained during an isolated single episode of a witnessed GTCS.

Global Reconstruction for Extensive Destruction in Tuberculosis of the Lumbar Spine and Lumbosacral Junction: A Case Report.

Study Design Case report. Objective To analyze the surgical difficulties in restoring global spinal stability and to describe an effective surgical option for tuberculosis with extensive destruction of the lumbosacral spine. Advanced tuberculosis with destruction of the lumbosacral spine can result in a kyphosis or hypolordosis, leading to back pain, spinal instability, and neurological deficits.

Surgical management of neglected fractures of the patella.

Between April 1996 and May 2002, 22 people (18 men, 4 women) were treated for neglected fractures of the patella at our hospital. The median patient age was 43 (range 22-55) years. The majority of the fractures were caused by a direct fall on the knee.
