Background/Objectives: Spinoplastic surgery is an emerging multidisciplinary field developed to address and reduce the complication of pseudoarthrosis following complex spinal reconstructions. While the number of spinal fusion procedures continues to rise every year, fusion failure rates remain as high as 40%. Although pseudoarthrosis may not always manifest clinically, it remains a leading cause of persistent pain and need for subsequent revision surgeries. The multidisciplinary collaboration between spine and plastic surgeons in spinoplastic surgery has therefore emerged as a proactive strategy aimed at preventing complications, particularly in patients identified as high-risk for pseudoarthrosis. As the patient population expands and spinoplastic surgery continues to evolve, refining patient selection criteria becomes essential for achieving optimal surgical outcomes. This review aims to provide a comprehensive overview of recent advancements in spinoplastic surgery, highlighting current indications, surgical techniques, recent case reports, and strategies for identifying suitable candidates. Methods: We performed a narrative review of English language literature through April 2025. Spinoplastic case reports and case series published within the last 20 years were included in the review. Results: Indications for use of a spinoplastic approach clustered into prior fusion failure, extensive oncologic resection, severe spinal deformity, procedures requiring extensive spinal involvement, and/or patients at risk for impaired bone healing. Succesful radiographic union and improvement of symptoms were widely reported across all 9 case reports/series. Conclusions: Although evidence is presently limited, spinoplastic surgery appears to achieve high bone graft fusion rates with acceptable morbidity and functional improvement in a carefully selected group of high-risk spinal reconstruction patients. Still, larger prospective studies are warranted to refine patient selection and validate functional benefit.

Abstract Robots have been used effectively in plastic and reconstructive surgery (PRS) for reconstruction. The utilization of robotics in all surgical specialties is expanding with the goal of offering the most appropriate patient-centered care possible, especially in complex multidisciplinary cases. Despite the safety, efficiency, and reproducibility of robotics in PRS, there is a paucity of required and formalized training in PRS residency programs. The ACGME and industry published guidelines were investigated. Robotic surgery case logs of Mayo Clinic Arizona General Surgery residents were analyzed with attention to equivalency certification (EQ). Over the past 5 years, the equivalency certification from Intuitive (Sunnyvale, CA) was obtained by 30% of all general surgery residents at our institution (range, 0–100). The case numbers to obtain the equivalence certification are industry recommendations, and proficiency is determined by the program director. The ACGME does not mandate robotics training in general surgery residency. According to the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES), trainees must complete 20 console cases and 10 bedside cases to become industry certified. With respect to training and advancing the field, PRS residents could successfully obtain certification in their residency programs. The minimum case requirement recommended by SAGES is not burdensome and can ensure robotic privileges in PRS practice immediately following graduation. By improving the training for minimally invasive robotic surgery in plastic surgery, patients and healthcare systems benefit from improved quality of life outcomes and decreased postoperative length of stay, which results in less strain on our entire medical system.

Background: Vertebral body defects pose a significant challenge in spinal reconstructive surgery. Compression fractures of the vertebral corpus are typically treated with vertebral augmentation procedures. There are significant risks associated with the introduction of foreign material in the spine, including infection and pseudarthrosis. Vascularized bone grafts (VBGs) have become a popular alternative for spinal reconstruction in the last decade thanks to their robust blood supply and autologous nature. VBGs have been described predominantly for the reconstruction of posterior vertebral defects. The objective of this study is to describe a novel procedure for the reconstruction of vertebral corpus defects in the lumbar and distal thoracic spine. Methods: This is a cadaveric anatomy study. The authors performed the novel surgical technique on an anonymized cadaveric donor in the prone position and recorded the procedure through clinical photography. Consent for the procedure and photography was obtained from the Center for Procedural Innovation. Results: A 5-cm-long posterior iliac crest VBG (IC-VBG) was successfully harvested on a pedicle of the quadratus lumborum muscle. The VBG was rotated and mobilized anteromedially to the vertebral corpus. In this donor, the IC-VBG could be inset with minimal tension anywhere along the vertebral bodies of the spine from the L5 to the T9 level. Conclusions: A rotated, anteromedially mobilized IC-VBG represents a novel technique for reconstruction of the anterior vertebral corpus of the lumbar and distal thoracic spine with a lower risk of infection and pseudarthrosis than reconstruction with foreign materials.

Background: Artificial intelligence (AI) is a promising tool to aid in diagnostic accuracy and patient communication. Prior literature has shown that ChatGPT answers medical questions and can accurately diagnose surgical conditions. The purpose of this study was to determine the accuracy of ChatGPT 4.0 in evaluating radiologic imaging of common orthopedic upper extremity bony pathologies, including identifying the imaging modality and diagnostic accuracy. Methods: Diagnostic imaging was sourced from an open-source radiology database for 6 common upper extremity bony pathologies: distal radius fracture (DRF), metacarpal fracture (MFX), carpometacarpal osteoarthritis (CMC), humerus fracture (HFX), scaphoid fracture (SFX), and scaphoid nonunion (SN). X-ray, computed tomography (CT), and magnetic resonance imaging (MRI) modalities were included. Fifty images were randomly selected from each pathology where possible. Images were uploaded to ChatGPT 4.0 and queried for imaging modality, laterality, and diagnosis. Each image query was completed in a new ChatGPT search tab. Multinomial linear regression was used to identify variations in ChatGPT’s diagnostic accuracy across imaging modalities and medical conditions. Results: Overall, ChatGPT provided a diagnosis for 52% of images, with accuracy ranging from 0% to 55%. Diagnostic accuracy was significantly lower for SFX and MFX relative to HFX. ChatGPT was significantly less likely to provide a diagnosis for MRI relative to CT. Diagnostic accuracy ranged from 0% to 40% with regard to imaging modality (x-ray, CT, MRI) though this difference was not statistically significant. Conclusions: ChatGPT’s accuracy varied significantly between conditions and imaging modalities, though its iterative learning capabilities suggest potential for future diagnostic utility within hand surgery.

Background/Objectives: Spino-plastic surgery describes a specialized, multidisciplinary approach to addressing various spinal pathologies. The field is the innovative product of a multidisciplinary collaboration between plastic and reconstructive, orthopedic, and neurosurgery. Over the last few decades, this collaboration has borne promising surgical techniques and treatment plans geared toward restoring form, function, and aesthetics in patients with a variety of spinal conditions, including failed fusions, pseudoarthrosis, and the need for oncologic reconstruction. This paper explores the application of spino-plastic surgery in the context of post-sarcoma resection reconstructions, focusing on the efficacy in addressing the unique challenges posed by extensive tissue loss and structural deformities. Methods: Our study reviews a series of cases wherein spino-plastic techniques were utilized in patients with sarcomas of the spine and adjacent structures. We also discuss the technical considerations, including preoperative planning, intraoperative challenges, and overall patient care, that are crucial for the success of spino-plastic procedures. Results: The outcomes demonstrate significant improvements in patient mobility, pain reduction, and overall quality of life. Most notably, spino-plastic surgical techniques help facilitate the restoration of functional anatomy by leveraging vascularized bone grafts and muscle flaps, thereby enhancing long-term stability and reducing the risk of complications such as nonunion or infection. Conclusions: Spino-plastic collaboration represents a pivotal advancement in oncologic treatment, spinal care, and reconstructive surgery, offering new hope for patients undergoing post-sarcoma reconstruction. Further research and refinement of the techniques will only expand their application and improve outcomes for a broader range of patients in the future.

ABSTRACT In the past two decades, plastic surgeons have advanced to the forefront of spinal surgery, joining orthopedic and neurosurgeons in the multidisciplinary field of spino-plastics. As the global disease burden grows with an increased incidence of spinal pathologies, vascularized bone grafts (VBGs) define the current frontier of spino-plastic surgery. Vascularized bone grafting involves lifting segments of bone with the muscular attachments but without the inclusion of a named vessel. When compared to traditional nonvascular bone grafts and allografts, VBGs have come forward as a favored technique for complex spinal reconstruction due to the unique opportunity to capitalize on the relationship between the tendons and Sharpey's fibers which maintain blood flow to both the bone and muscular segments. This technique ensures robust autologous tissue rearrangement and also takes advantage of the osteoinductive properties of the bone segments, promoting adequate structural support and the perfusion necessary for efficient direct healing and fusion in intricate spine reconstructions. Another one of the many favorable qualities of VBGs is the diversity of sources available to surgeons. The review explores the role of VBGs in enhancing spinal fusion rates and minimizing morbidity compared to traditional approaches. Additionally, a detailed examination of six common VBG sources-the iliac crest, ribs, medial scapula, occiput, spinous processes, and clavicle is included, highlighting each graft's specific techniques and emphasizing the range of options available to spino-plastic surgeons.
