Background/Objectives: Primary spinal sarcomas, encompassing both bone and soft tissue histotypes, demand individualized reconstruction due to heterogeneous tumor biology, anatomic complexity, and host environments compromised by radiation, systemic therapy, or prior surgery. This narrative review reframes post-resection spinal reconstruction through a precision-medicine lens. Methods: A structured literature review was performed using PubMed and Scopus, targeting articles published between 2000 and 2026. Searches encompassed spinal sarcoma reconstruction, radiation and fusion, biologic reconstruction, and emerging technologies. Results: Tumor grade, radiation exposure, and systemic therapy timing emerge as multiplicative determinants of reconstructive environment quality, with drug-class-specific perioperative effects warranting stratified management. Vascularized bone grafts achieve reliable fusion in compromised hosts where avascular constructs fail. A precision-oriented reconstructive ladder is proposed as a conceptual, hypothesis-generating framework to guide strategy selection. Hybrid PSI-VBG constructs may further expand reconstructive possibilities. The evidence base remains largely composed of small, retrospective series. Conclusions: Individualized strategies anchored in tumor biology and host environment are the cornerstone of durable spinal sarcoma reconstructions. The proposed framework requires prospective, multi-institutional validation. Standardized outcome definitions, prospective registries, and histotype-stratified analyses are needed to advance the field.

Spinal sarcomas are rare, aggressive tumors requiring wide resection that creates large, challenging defects. Conventional reconstruction using allografts or metallic implants is prone to failure in compromised settings like irradiated or infected tissue. This narrative review synthesizes the literature on biologic reconstruction strategies, focusing on vascularized bone grafts (VBGs) and the ‘spinoplastic’ reconstruction approach, to provide a clinical framework for their application. We performed a narrative literature review using PubMed and Scopus to synthesize clinical studies describing biologic spinal reconstruction in compromised host beds. The main findings show that pedicled VBGs (e.g., rib, iliac crest) and free VBGs (e.g., fibula) function as living structural components. ‘Spinoplastic’ reconstruction leverages these grafts to promote biologic fusion, with clinical series reporting high union rates, even in irradiated or revision settings, offering a durable alternative to avascular constructs. Biologic reconstruction using VBGs is a critical strategy for achieving durable spinal stability in these challenging scenarios, and future directions point toward hybrid strategies combining 3D-printed implants with the biologic power of VBGs.

Abstract The da Vinci Single-Port (SP) system is a robotic surgery platform that allows access into the abdominal cavity through a single short surgical incision. The omentum is an attractive donor site for vascularized omental lymph node transfer (VOLT) in the treatment of lymphedema. We hypothesize that SP robotic VOLT will allow for improvement in perioperative outcomes as compared to open laparotomy for omental flap harvest. A retrospective cohort study was performed, comprised of a study sample of patients with a diagnosis of lymphedema who presented to our institution for VOLT using either an open or SP robotic technique between May 2020 and February 2023. The primary outcome was length of hospital stay. The secondary outcomes included intraoperative complication rate, postoperative complication rate, and length of surgery. Fifteen patients underwent da Vinci SP omental flap harvest, and 14 patients underwent open harvest. There was no significant difference in average age, BMI, sex, or lymphedema etiology between the two groups. Average length of stay was 2.2 ± 1.7 days in the SP group and 2.3 ± 2.1 days in the open group (p = 0.91). There were no significant differences in terms of intraoperative or postoperative complications between the two groups. Ninety-three percent of SP robotic and 86% of open patients reported at least partial subjective improvement following VOLT (p = 0.50). Our findings suggest that SP robotic omental harvest for VOLT is feasible. Perioperative outcomes show comparable results in terms of length of hospital stay, complications, and subjective postoperative improvement when comparing the open to the SP approach.

Abstract Abdominally based free flaps are commonly utilized in the context of breast reconstruction. Historically, postoperative care of these patients involved liberal amounts of intravenous fluid administration; however, overadministration of fluids puts patients at risk of developing flap edema via fluid shifts, electrolyte imbalances, wound dehiscence, and other sequelae. The purpose of this study is to assess fluid administration trends in this cohort at the authors' institution and assess its impact on patient outcomes. A retrospective review was performed on patients who underwent free-flap breast reconstruction. Patient demographics and hospitalization data were collected, and type of abdominal flap and reconstruction timing was noted. Perioperative fluid administration volumes were tracked, and primary outcomes included complication rate and type (e.g., acute blood loss anemia [ABLA], partial/total flap loss, etc.). Multivariable logistic regression was performed to assess the impact of fluid volume on patient outcomes. A total of 115 patients (mean age of 51.3 ± 10.5 years) underwent 188 abdominally based free flaps. Deep inferior epigastric artery perforator flaps were performed most often (n = 91), followed by muscle-sparing transverse rectus abdominis flaps (n = 88). Multivariable logistic regression demonstrated that high perioperative fluid administration (≥9,000 mL) was associated with increased odds of medical complications (odds ratio [OR] = 21.7; confidence interval [CI]: 5.54–84.5; p < 0.001). Patients with high fluid administration volumes experienced an increased (but nonstatistically significant) flap complication rate (OR = 2.96; CI: 0.89–9.88; p = 0.08) and developed ABLA at a higher rate (OR = 15.86; CI: 5.30–46.4; p < 0.001). High-volume resuscitation (≥9,000 mL) was associated with increased odds of ABLA as well as a greater likelihood of medical and flap complications in patients undergoing abdominally based free flaps for breast reconstruction. These data should be used to guide the development of protocols within institutions, which perform free flaps for breast reconstruction.
