Quantitative analysis of local bone graft harvested from the posterior elements during posterior spinal fusion in Adolescent Idiopathic Scoliosis patients by Choo, Qi Qi, Chiu, Chee Kidd, Lisitha, Kulathunga Arachchige, Chan, Chris Yin Wei, Kwan, Mun Keong

“…Objective: This study analyses the quantity of local bone graft obtained from different anatomical parts of the posterior elements during corrective surgery for Adolescent Idiopathic Scoliosis patients. Summary of background data: Locally harvested autogenous bone graft eliminates possible donor site morbidity and has all the important basic bone graft properties such as osteoinductivity, osteogenicity and osteoconductivity. …”

Zonal differences in risk and pattern of pedicle screw perforations in adolescent idiopathic scoliosis (AIS): a computerized tomography (CT) review of 1986 screws by Chan, Chris Yin Wei, Kwan, Mun Keong

“…Objective: The objective of this study was to determine whether combined total intravenous anesthesia (TIVA) technique with propofol/remifentanil is associated with less SSEP suppression when compared to combined volatile agent desflurane/remifentanil anesthesia during corrective scoliosis surgery at a comparable depth of anesthesia. …”

Radiological and clinical outcome of selective thoracic fusion for patients with Lenke 1C and 2C adolescent idiopathic scoliosis with a minimum follow-up of 2 years by Kwan, Mun Keong, Chiu, Chee Kidd, Tan, Pheng Hian, Chian, Xue Han, Ler, Xin Yi, Ng, Yun Hui, Ng, Sherwin Johan, Goh, Saw Huan, Chan, Chris Yin Wei

“…Methods: Forty-four patients with Lenke 1C and 2C curves with adolescent idiopathic scoliosis who underwent STF were reviewed. Radiological parameters and Scoliosis Research Society (SRS)-22r scores were assessed preoperatively, postoperatively, and on final follow-up. …”

Cervical Supine Side-Bending versus Cervical Supine Traction Radiographs: Which Is Better in Predicting Proximal Thoracic Flexibility for Lenke 1 and 2 Adolescent Idiopathic Scoliosis? by Chiu, Chee Kidd, Bashir, Elrofai Suliman, Chan, Chris Yin Wei, Kwan, Mun Keong

“…Purpose: This study compared cervical supine side-bending (CSSB) and cervical supine traction (CST) radiographs to assess the flexibility and predict the correctability of the proximal thoracic (PT) curve for patients with adolescent idiopathic scoliosis (AIS) classified as Lenke 1 and 2. Overview of Literature: Knowledge of the flexibility of the PT curve is crucial in the management of patients with AIS. …”

Single vs two attending senior surgeons: assessment of intra-operative blood loss at different surgical stages of posterior spinal fusion surgery in Lenke 1 and 2 adolescent idiopathic scoliosis by Kwan, Mun Keong, Chiu, Chee Kidd, Chan, Chris Yin Wei

“…Methods: Lenke 1 and 2 adolescent idiopathic scoliosis (AIS) patients who underwent instrumented posterior spinal fusion (PSF) surgery from two centres between June 2014 and December 2015 were prospectively recruited into this study. …”

Posterior Spinal Fusion in a Scoliotic Patient With Congenital Heart Block Treated With Pacemaker: An Intraoperative Technical Difficulty by Wong, Tat Seng, Abu Bakar, Jaseemuddeen, Chee, Kok Han, Hasan, Mohd Shahnaz, Chung, Weng Hong, Chiu, Chee Kidd, Chan, Chris Yin Wei, Kwan, Mun Keong

“…OBJECTIVE: To describe the technical difficulties on performing posterior spinal fusion (PSF) on a pacemaker-dependent patient with complete congenital heart block and right thoracic scoliosis. SUMMARY OF BACKGROUND DATA: Congenital complete heart block requires pacemaker implantation at birth through thoracotomy, which can result in scoliosis. …”
