Purpose Osteoporosis is a common, but challenging phenomenon to overcome in adult spinal deformity (ASD) surgery. Several pharmacological agents are at the surgeon’s disposal to optimize the osteoporotic patient prior to undergoing extensive reconstruction. Familiarity with these medications will allow the surgeon to make informed decisions on selecting the most appropriate adjuncts for each individual patient. Methods A comprehensive literature review was conducted in PubMed from September 2021 to April 2022. Studies were selected that contained combinations of various terms including osteoporosis, specific medications, spine surgery, fusion, cage subsidence, screw loosening, pull-out, junctional kyphosis/failure. Results Bisphosphonates, denosumab, selective estrogen receptor modulators, teriparatide, abaloparatide and romosozumab are all pharmacological agents currently available for adjunctive use. While these medications have been shown to have beneficial effects on improving bone mineral density in the osteoporotic patient, varying evidence is available on their specific effects in the context of extensive spine surgery. There is still a lack of human studies with use of the newer agents. Conclusion Bisphosphonates are first-line agents due to their low cost and robust evidence behind their utility. However, in the absence of contraindications, optimizing bone quality with anabolic medications should be strongly considered in preparation for spinal deformity surgeries due to their beneficial and favorable effects on fusion and hardware compared to the anti-resorptive medications.

Fragility fractures, particularly in the hip and spine, are the most common complication of osteoporosis. In the US, approximately 1-1.5 million vertebral compression fractures (VCFs) occur annually. While patients may present with sudden onset of low back pain and limited mobility, more than two-thirds of VCFs are asymptomatic and are detected incidentally. X-rays are the standard imaging modality for diagnosis, with CT and MRI indicated if neurological deficits are present or a malignant cause is considered. Initial management is often non-surgical, with medications, physical therapy, and bracing. Surgical management in the form of cement augmentation (kyphoplasty or vertebroplasty) or instrumented fusion can be considered after failure of non-operative treatment, cases of deformity, or neurologic deficits. Subsequent VCFs occur frequently, and risk factors for refracture include advanced age, low bone mineral density, and low BMI. Treatment of primary VCFs with anti-resorptive medication is essential to reduce the risk of subsequent fractures.Fragility fractures, particularly in the hip and spine, are the most common complication of osteoporosis.

Normal pressure hydrocephalus (NPH) and degenerative cervical myelopathy (DCM) can each lead to gait dysfunction and urinary incontinence and may occur concurrently in some patients. In patients presenting with NPH and DCM, there is a paucity of literature describing the medical and surgical complications of treatment and the potential consequences of the sequence of surgical procedures. The aim of this study is to evaluate patients with DCM, NPH, and dual pathology to determine epidemiology and how the order of surgical intervention for both conditions may impact complications and patient outcomes. The PearlDiver Mariner database was queried between 2010 and 2020 to identify patients by their diagnosis of NPH, DCM, or both. Additional groups were created to identify cohorts of patients who underwent ventriculoperitoneal (VP) shunting, DCM surgery, or both surgeries, as determined by the CPT, ICD9, and ICD10 codes included in the dataset. Overall demographics were reported for these cohorts of patients including age, gender, and region. Multivariable logistic regression, controlling for age, sex, and Charlson Comorbidity Index, was used to calculate odds ratios for the rates of perioperative complications within 1 year of initial ventriculoperitoneal (VP) shunt and/or DCM surgery. A total of 825,989 patients were identified with DCM and/or NPH: 725,433 (87.8%) had myelopathy alone, 96, 411 (11.7%), had NPH alone, and 4145 patients (0.5%) had both NPH and DCM. Of all patients with NPH, 4.8% underwent DCM surgery. Of all patients with DCM, 0.08% underwent VP shunting. Compared to NPH only patients who underwent VP shunting, patients with both pathologies undergoing VP shunting had higher odds of revision at 1-year (OR: 1.33, p-value: 0.04) and 5-years (OR: 1.36, p-value: 0.011), as well as spinal cord injury (OR: 7.77, p-value 0.016), dysphonia (OR: 2.88, p-value: 0.004), cervicalgia (OR: 2.95, p-value: 0.004), cervical kyphosis (OR: 17.49, p-value: 0.004), and limb paralysis (OR: 2.02, p-value: 0.002). Compared to DCM only patients who underwent DCM surgery, patients with both pathologies undergoing DCM surgery had higher odds of cardiac complications (OR: 1.12, p-value: 0.002), dural tear (OR: 1.66, p-value: 0.029), and dysphagia (OR: 1.28, p-value: <0.001). Patients who underwent VP shunting prior to DCM surgery had higher odds of revision shunting surgery at 1-year (OR:1.61, p-value:0.03) and 5- years (OR:2.16, p-value: <0.001). This is the largest study to date examining patients with dual cervical myelopathy and normal pressure hydrocephalus. Surgeons should carefully consider the order of VP shunting and DCM surgery, as complication rates differ depending on the order in which these surgeries are performed. Shunt revision is more common when VP shunting is performed prior to spinal decompression. •Normal pressure hydrocephalus and cervical spondylotic myelopathy may occur concurrently.•Surgeons should consider the order of VP shunting and CSM surgery, as complication rates differ depending on order.•Shunt revision is more common when VP shunting is performed prior to spinal decompression.

(1) Background: Length of stay (LOS) is a commonly reported metric used to assess surgical success, patient outcomes, and economic impact. The focus of this study is to use a variety of machine learning algorithms to reliably predict whether a patient undergoing posterior spinal fusion surgery treatment for Adult Spine Deformity (ASD) will experience a prolonged LOS. (2) Methods: Patients undergoing treatment for ASD with posterior spinal fusion surgery were selected from the American College of Surgeon’s NSQIP dataset. Prolonged LOS was defined as a LOS greater than or equal to 9 days. Data was analyzed with the Logistic Regression, Decision Tree, Random Forest, XGBoost, and Gradient Boosting functions in Python with the Sci-Kit learn package. Prediction accuracy and area under the curve (AUC) were calculated. (3) Results: 1281 posterior patients were analyzed. The five algorithms had prediction accuracies between 68% and 83% for posterior cases (AUC: 0.566–0.821). Multivariable regression indicated that increased Work Relative Value Units (RVU), elevated American Society of Anesthesiologists (ASA) class, and longer operating times were linked to longer LOS. (4) Conclusions: Machine learning algorithms can predict if patients will experience an increased LOS following ASD surgery. Therefore, medical resources can be more appropriately allocated towards patients who are at risk of prolonged LOS.

Background Lumbar spine fractures are common injuries associated with substantial morbidity for patients and socioeconomic burden. This study sought to epidemiologically analyze lumbar spine fractures by mechanism of injury and identify temporal trends in patient demographics and disposition, which few studies have previously evaluated. Materials and Methods A retrospective analysis was done of the US National Electronic Injury Surveillance System (NEISS) database between 2003 and 2022. The sample contained all patients 2 to 101 years old with product-related lumbar fractures presenting to participating institutions' emergency departments. A total of 15,196 unweighted injuries (642,979 weighted injuries) were recorded. Results Overall, there was a 20-year incidence rate of 10.14 cases per 100,000 person-years with a 2-fold increase in fracture incidence. Females were more prone to lumbar fracture than males (P=.032). Injuries primarily stemmed from a fall (76.6%). The incidence of lumbar fracture increased most significantly in older patients, with patients 80 years and older showing the greatest annual increase (β=8.771, R2=0.7439, P<.001) and patients 60 to 69 years showing the greatest percent increase with a 3.24-fold increase in incidence. Most (58.9%) of the fractures occurred at home. Females were more often injured at home compared with males (P<.001), who more often sustained lumbar fractures during recreational or athletic activity (P<.001). All patients older than 40 years showed at least a doubling in incidence rate of lumbar fracture between 2003 and 2022. Conclusion These data demonstrate the pressing need to address poor bone health in the aging population, shown here to have an increasing fracture burden. [Orthopedics. 2024;47(6):e297–e302.]

Surgical robots were first proposed in the 1960s with subsequent development and clinical implementation in the 1980s and 1990s. Recent advances in technology have led to widespread utilization of robots in many surgical subspecialties. In spine surgery, robots are primarily utilized for pedicle screw placement, with several studies highlighting the potential benefits of improved accuracy and reduction in radiation exposure. Once streamlined, robotic spine surgery (RSS) can provide financial renumeration through potential cost savings and marketing benefits, and in the future will likely aid in more complex surgeries. In Rhode Island, this technology has been implemented and has the potential to deliver optimized outcomes for patients. Robotic spine surgery is not a substitute for a skilled spine surgeon however, and careful diagnosis, care planning, and surgical execution are still mandatory to deliver the best possible patient outcomes. In this review, we chronicle the history of RSS, outline currently available RSS platforms, describe the efficacy, risks, and complications of RSS procedures, and explain the current and future utilization of RSS in Rhode Island.
