Despite the obvious success of arthroplasty trapeziectomy with or without interposition and prosthesis--in the treatment for trapeziometacarpal osteoarthritis, one may question the value of an arthrodesis in particular situations. In most reported series the outcome is reasonably successful, but when comparing the results of arthrodesis with arthroplasty, there is convincing evidence that the latter gives better outcomes. Considering the overall complication rate, and more specifically the incidence of nonunion after trapeziometacarpal fusion, it can be reasonably concluded that the latter should be reserved for specific indications.

Background: Scoliosis surgery performed in a prone position may result in thoracic anatomical compression and alter local hemodynamics, increasing surgical risk, especially in patients with pectus excavatum. Most commonly, refractory hypotension is the first symptom of these circulatory changes. Here, we report a case with scoliosis and pectus excavatum under posterior spinal fusion that presented as a progressive decrease in the partial pressure of end-tidal CO (PCO) as the first symptom in the prone position.

Background: Anterior cervical corpectomy and fusion (ACCF) involves placement of a graft/implant to ensure fusion and stabilization along with neural decompression. We share our experience with a subset of ACCF patients in whom graft/implant could not be placed post decompression for varying reasons but had a favorable long-term outcome. The necessity for routine fusion after corpectomy is critically analyzed, and the feasibility of an alternative surgical option without graft/implant is discussed.

Purpose: To investigate the role of Mini Nutritional Assessment-Short Form (MNA-SF) in predicting postoperative complications in older patients (≥75 years) undergoing lumbar fusion surgery.
Patients And Methods: Patients who had undergone posterior lumbar fusion surgery between June 2019 and September 2021 were enrolled. Those with an MNA-SF score of 12 or higher were categorized as the Nourished group, while those with a score less than 12 were placed in the Malnutrition-Risk group.
Objective: The authors investigated the predictors of cost of admission (CoA) for robot-assisted pedicle screw placement to assess the value of robotic systems in spine operations.
Methods: Demographic, operative, and postoperative variables were retrospectively collected from 506 patients undergoing robot-assisted spine surgery utilizing the ExcelsiusGPS robot at two high-volume tertiary care centers from 2017 to 2023. Perioperative parameters were evaluated against total hospital admission cost utilizing the Kruskal-Wallis and Wilcoxon rank-sum tests followed by multivariable linear regression.
Objective: An increasing number of studies have shown that a robotic guidance system (RGS) can provide accurate cervical pedicle screw (CPS) placement. The accuracy of CPS placement with an RGS has mostly been evaluated according to the magnitude of pedicular cortical violation. However, an RGS assists in pedicle screw (PS) placement by directly indicating the preplanned trajectory in the operative field.
