The use of volatile anesthetics in patients undergoing coronary artery bypass grafting resulted in a shorter length of stay (LOS) in the intensive care unit, shorter LOS in the hospital, and a decreased need for prolonged intensive care. Volatile anesthetics exert cardioprotective effects by anesthetic preconditioning in patients at risk of myocardial ischemia. Sarcolemmal and mitochondrial ATP-dependent potassium channels are the key for anesthetic preconditioning. However, no clinical study has shown that the perioperative use of volatile anesthetics in patients undergoing coronary surgery contributes to a reduced perioperative mortality. For the first time, the study from De Hert and colleagues clearly demonstrates that inhalational anesthesia results in a reduced perioperative cardiac morbidity. In the authors opinion, cardioprotection by activation of ATP-dependent potassium channels will become part of any cardiac revascularization procedure in the future.

Spinal Cord Stimulation for Prolonged Disorders of Consciousness: A Study on Scalp Electroencephalography.
CNS Neurosci Ther
December 2024
Department of Functional Neurosurgery, The Affiliated Brain Hospital of Nanjing Medical University, Nanjing, China.
Background: Patients with disorders of consciousness (DOC) undergoing spinal cord stimulation (SCS) for arousal treatment require an assessment of their conscious state before and after the procedure. This is typically evaluated using behavioral scales (CRS-R), but this method can be influenced by the subjectivity of the physician. Event-related potentials (ERP) and EEG power spectrum are associated with the recovery of consciousness.

Background: Soft-tissue sarcoma involving the popliteal fossa remains challenging because it is difficult to achieve wide margins with limb salvage in this location. Adjuvant therapy is frequently necessary, and limb function can be adversely affected. We reviewed our experience with these tumors.

Background: Obesity has been consistently proven to be associated with an increased risk of dislocation following total hip arthroplasty (THA). As the prevalence of obesity continues to rise globally, it is of vital importance to minimise risks, including dislocation rates, in these patients undergoing THA.
Methods: We describe a series of patients with obesity, morbid obesity (BMI ≥ 40) and super-obesity (BMI ≥ 50) undergoing THA at our institution over a 10-year period using a dual-mobility acetabular cup.
Outcomes of All-Inside Arthroscopic ACL Reconstruction with Lateral Extra-Articular Tenodesis (ACLR + LET).
Indian J Orthop
January 2025
Department of Orthopaedics, Kalinga Institute of Medical Sciences, KIIT University, Bhubaneshwar, Odisha 751024 India.
Background: Anatomic single-bundle ACL reconstruction (ACLR) produces good results when the graft and tunnel are positioned in the anatomic footprint on the femoral and tibial insertion sites in a more oblique orientation. The of the knee and its biomechanical role in controlling rotational laxity, internal rotation, and pivot shift has led to adding adjunctive procedures like extra-articular augmentation and lateral extra-articular tenodesis (LET) to decrease rotational laxity. We prospectively analyzed young adults with rotational instability and generalized laxity undergoing an arthroscopic single bundle ACLR with an additional LET procedure.

Department of Orthopaedics, Apollo Hospitals, Greams Road, Chennai, 600006 India.
Background: Ultracongruent (UC) total knee replacement (TKR) designs, serving as alternatives to posterior stabilized (PS) and cruciate retaining (CR) designs, lack conclusive evidence regarding posterior femoral rollback. This study aimed to compare intraoperative posterior femoral rollback and maximal knee flexion between UC and PS inserts, addressing the paucity of literature on femoral rollback achieved with UC designs in total knee replacement.
Methods: A consecutive cohort of 20 patients undergoing robotic-assisted primary total knee replacement, posterior femoral rollback and maximal intraoperative knee flexion were assessed.
