ABSTRACT
OBJETIVO: Describir las tendencias en reconstrucción de LCA (R-LCA) entre los traumatólogos ejerciendo en Chile, delineando sus preferencias en cuanto a la técnica quirúrgica. MÉTODO: encuesta online de selección múltiple y recolección anónima de datos, dirigida a todos aquellos cirujanos que realizan R-LCA en Chile. Fue enviada por correo electrónico desde la Sociedad Chilena de Ortopedia y Traumatología a todos sus afiliados. RESULTADOS: 103 cirujanos completaron la encuesta, realizando su práctica quirúrgica en Santiago (53%) y regiones (47%). En el 53% de los encuestados la cirugía de rodilla representaba más del 75% de su práctica, mientras que sólo en 9 ellas eran menos del 25%. El autoinjerto de isquiotibiales es utilizado en el 70% de R-LCA, seguido por el autoinjerto de tendón patelar (27%). En cuanto a la preparación de túneles, 33% utiliza técnica transtibial y 67% túneles independientes (13% fresado retrógrado, 54% portal medial). Para la fijación de injerto isquiotibiales, botones corticales es lo más utilizado en el fémur (73%), y tornillos interferenciales en la tibia (82%). Para la fijación femoral y tibial de injerto de tendón patelar, los tornillos metálicos son los más utilizados (75%). Un 41% realiza un pretensado del injerto, un 59% lo ciclan una vez fijo, y sólo 8 aplican una solución antibiótica sobre el injerto. La mayoría (89%) realiza la fijación en 10°-20° de flexión, ya sea con rotación externa (36%) o neutra (53%). En un 7% de las R-LCA primarias y en un 27% de las revisiones agregan una reconstrucción anterolateral. CONCLUSIÓN: la tendencia en R-LCA en Chile es el uso de autoinjerto de isquiotibiales, con fresado independiente del túnel femoral y fijación en flexión con botones corticales y tornillos interferenciales.
OBJECTIVE: To describe the trends in anterior cruciate ligament reconstruction (ACL-R) among Orthopaedic surgeons working in Chile, outlining their preferences regarding surgical technique. METHOD: An online, multiple choice, anonymous survey was sent via email from the Chilean Orthopaedic and Trauma Society to all its members, with instructions to be completed by surgeons who perform ACL-R. RESULTS: 103 surgeons completed the survey from Santiago (53%) and other regions (47%). For 53% of the surgeons, knee surgeries represented more than 75% of their practice, and in only 9 cases it was less than 25% of it. The autologous hamstring tendon graft was in 70% of the ACL-R, while patellar tendon graft in 27%. For tunnel drilling, 33% of surgeons use transtibial technique, and 67% prefer independent tunnel drilling (13% retrodrill, 54% medial portal). Fixation method for hamstring tendon graft is mostly with cortical buttons on femur (73%), and interference screws for the tibia (82%). Patellar graft was fixed with metal screws (75%) in both femur and tibia. 41% of surgeons pretensed the graft, 59% cycle it once, and only 8 coated the graft with antibiotic solutions. Most (89%) fixate de graft in 10°-20° of knee flexion, with either external rotation (36%) or neutral (53%). Antero-lateral reconstruction is used in 7% of primary ACL-R and in 27% of revision surgeries. CONCLUSION: the chilean tendency for ACL-R is to use an autologous hamstring tendon graft, with independent drilling technique, and fixation with cortical buttons and interference screws for femur and tibia respectively.

Data on isolated coronary artery bypass grafting (CABG) performed in 2017 and 2018, and registered in the Japan Cardiovascular Surgery Database were reviewed for preoperative characteristics, postoperative outcomes, and choice of graft material for the left anterior descending artery (LAD). Isolated CABG was performed off-pump in 54.6% (n＝14,684) of all CABG cases (n＝26,913), and graft material for the LAD was left internal thoracic artery in 76.4% and right internal thoracic artery in 19.0%. Operative mortality was 1.5% in elective cases (On-pump CABG : ONCAB 1.9%, off-pump CABG : OPCAB 1.2%, p＜0.001), 7.4% in emergency cases (ONCAB 10.2%, OPCAB 4.3%, p＜0.001), and 2.5% overall. Postoperative morbidity was low in almost all aspects in OPCAB, and average JapanSCORE II is elevating every year. Overall short-term operative results for isolated CABG is stable, and operative candidates are shifting to higher-risk patients.
ABSTRACT
We reviewed the data of the isolated coronary artery bypass grafting (CABG) procedures performed in 2015 and 2016, as registered in the Japan Cardiovascular Surgery Database, for preoperative characteristics, surgical outcomes, and the choice of graft material used for the left anterior descending artery (LAD). Isolated CABG was performed off-pump in 55.0% (n = 16,173) of all CABG cases (n = 29,392). The left internal thoracic artery and the right internal thoracic artery were used as the graft materials in 72.1 and 17.4% cases respectively. The operative mortality rates remained unchanged since the last report, with 1.7% for elective cases, 8.8% for emergency cases, and 3.0% overall. In elective cases, the operative mortality rate was 1.1% for off-pump CABG (OPCAB) compared with 2.5% for on-pump CABG. The morbidity rates for all OPCAB cases were significantly better except for those falling in the ‘readmission ＜30 days’ group.
ABSTRACT
STUDY DESIGN: A review of the literature. OBJECTIVES: To review the current evidence on the development of a viable surgical strategy for successful treatment of patients with osteoporotic vertebral fractures. SUMMARY OF LITERATURE REVIEW: Achieving rigid and stable spinal column reconstruction in elderly patients with osteoporosis is challenging because of the poor healing capacity and weak mechanical strength of their bones. MATERIALS AND METHODS: A literature search of clinical and biomechanical studies on the issues of surgical treatment of patients with osteoporotic vertebral collapse was performed and reviewed in terms of the surgical approach, fixation, graft material, and medical considerations. Illustrative cases of the authors' experiences were presented and reflected upon. RESULTS: Posterior spinal fusion and vertebral augmentation showed shorter operating times, less bleeding, and fewer complications with comparable or superior clinical results than anterior corpectomy and fusion or a posterior closing wedge vertebral shortening procedure in multiple studies. Therefore, we recommend the former as a first-line surgical plan for patients with osteoporotic vertebral collapse. However, in some patients who suffer fixed kyphosis, or spinal cord compression by a retropulsed bony fragment or bone cement, or infected vertebroplasty, an anterior approach could be considered to remove the pertinent lesion and to restore anterior spinal column. For the enhancement of the purchasing strength of the screw in the osteoporotic vertebra (e), a technique of prefilled bone cement in the instrumented vertebra(e) or injection of bone cement through a fenestrated screw is useful. Further, preoperative assessment and correction of systemic and local factors that affect bone healing is required when spinal fusion surgery is considered in elderly osteoporotic patients. The selection of the graft material should be individualized according to the property among osteoconduction, osteoinduction, and ostegenesis, or structural support that is the most important for the successful bone healing of each patient. CONCLUSIONS: Comprehensive geriatric assessment and management of elderly patients before surgery and careful and meticulous surgical planning with respect to the surgical approach, instrumentation, and the graft material are important to achieve the best outcome of the surgical treatment of patients with osteoporotic vertebral collapse.

Objective To investigate the clinical choice on graft size and the type of donor's hepatectomy in adult living related partial liver transplantation. Methods The literatures in recent years on the donor's evaluation, the size of liver grafts, the types of donor hepatectomy and safety of donor in adult living related partial liver transplantation were reviewed.Results The size of liver graft is a crucial factor related to the safety of donor and the prognosis of the recipient. GW/ESLW≥30%, GW/BW≥0.8% may be the lowest limits. Left lobe contained middle hepatic vein, extended left lobe with left-side caudle lobe, right lobe or extended right lobe contained middle hepatic vein may be the practical choice.Conclusion It is important to make a reasonable choice of liver graft according to the estimation of GW/ESLW or GW/BW, and the anatomy of liver in adult living related partial liver transplantation.
