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.

Background Secondary lymphedema frequently occurs following surgery, malignancy, trauma, or radiation and is characterized by limb swelling, discomfort, and recurrent infections. Two advanced supermicrosurgical techniques—lymphovenous anastomosis (LVA) and vascularized lymph node transfer (VLNT)—have recently gained popularity as treatment options. However, long-term outcome data for these procedures remain limited. This systematic review and meta-analysis aim to evaluate the long-term efficacy of LVA and VLNT in patients with secondary lymphedema followed for more than 2 years postoperatively, focusing on outcomes such as cellulitis rates and limb circumference. Methods This study followed the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Inclusion criteria encompassed studies involving adult patients with secondary lymphedema treated with LVA or VLNT and with at least 24 months of follow-up. The primary outcomes were annual cellulitis incidence and limb circumference change, analyzed separately for upper and lower extremities. Meta-analysis was conducted using R version 4.3.1. Pooled effect sizes were estimated using random-effects models. Subgroup and sensitivity analyses were also performed. Results A total of 23 studies met the inclusion criteria, covering 648 limbs treated with either LVA (n = 216) or VLNT (n = 432). The weighted average patient age was 56.3 years, and the cohort was predominantly female (99.9%). For LVA, the pooled mean reduction in annual cellulitis events was −1.13 (95% confidence interval [CI], −1.70 to −0.57) for upper extremities and −1.32 (95% CI, −2.08 to −0.55) for lower extremities. VLNT yielded greater reductions in cellulitis, with pooled mean differences of −2.43 (95% CI, −3.36 to −1.50) and −1.38 (95% CI, −2.11 to −0.65) for upper and lower limbs, respectively. Additionally, VLNT reduced limb circumference by 42.7% (95% CI, 36.7–49.7) in upper extremities and 21.98% (95% CI, 19.8–24.4) in lower extremities. Conclusion LVA and VLNT both result in durable, long-term improvements in cellulitis rates, and VLNT was shown to reduce limb circumference. Given the significant impact on patient quality of life, these interventions should remain integral to the treatment algorithm for secondary lymphedema.

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.

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.

Summary: Sacral reconstruction post tumor resection has historically been executed with the placement of hardware or free tissue transfer. Reconstruction using a vascularized bone graft is an alternative that avoids the complications associated with hardware placement or free tissue transfer. This article describes the first documented case of spinoplastic reconstruction using an iliac crest vascularized bone graft (IC-VBG) after the resection of a sacral ependymoma. This is a case of a 17-year-old boy with a history of a sacral myxopapillary ependymoma. He presented to a local emergency department complaining of 6 months of urinary incontinence and progressive paresthesias affecting the left lower extremity. Magnetic resonance imaging was significant for a lesion located in the extradural spinal canal. Biopsy confirmed a myxopapillary ependymoma, World Health Organization grade II. The initial intervention involved tumor resection with titanium hardware placement. He subsequently required replacement of the titanium hardware with carbon fiber, secondary to the need for surveillance imaging. He underwent harvesting and inset of the IC-VBG at the time of hardware replacement. IC-VBG is a safe and effective modality for spinoplastic reconstruction. It enhances the potential for solid bony union and offers a practical alternative to free bone transfer. This approach provides an asset to add to a reconstructive surgeon’s armamentarium, making it an essential tool for reconstructive surgeons working in conjunction with spinal surgery colleagues.

Summary: The number of spinal reconstruction cases is growing, as are the accompanying complications. Wound complications after spinal reconstruction can be fatal and can affect up to 19% of patients undergoing major spine surgery. The discipline of spinoplastic surgery is characterized by the use of vascularized bone grafts to reconstruct spinal defects, which provide better results compared with nonvascularized and allogenic equivalents, owing to their superior blood supply. We present a 49-year-old man with spinal defect in the C3-C7 region treated with spinoplastic reconstruction. A 5 × 6 cm occipital VBG was designed with a centrally located muscular pedicle and successfully inset into the osseous defect. Radiographs taken 15 months postoperatively demonstrated overall excellent bony fusion, and the patient made an appropriate clinical recovery. In difficult spine procedures, the use of this occipital vascularized bone graft may lead to higher fusion rates without the need for free tissue transfer or allograft placement, which may not be available at all surgical centers around the world.
