Predictive Modeling of Length of Hospital Stay Following Adult Spinal Deformity Correction: Analysis of 653 Patients with an Accuracy of 75% within 2 Days.

Safaee, Michael M; Scheer, Justin K; Ailon, Tamir; Smith, Justin S; Hart, Robert A; Burton, Douglas C; Bess, Shay; ... (16 authors) (World neurosurgery, 2018-07)

Length of stay (LOS) after surgery for adult spinal deformity (ASD) is a critical period that allows for optimal recovery. Predictive models that estimate LOS allow for stratification of high-risk patients.A prospectively ...

Peak Timing for Complications After Adult Spinal Deformity Surgery.

Daniels, Alan H; Bess, Shay; Line, Breton; Eltorai, Adam EM; Reid, Daniel BC; Lafage, Virginie; Akbarnia, Behrooz A; ... (23 authors) (World neurosurgery, 2018-07)

Overall complication rates for adult spinal deformity (ASD) surgery have been reported; however, little data exist on the peak timing associated with specific complications. This study quantifies the peak timing for multiple ...

Comparable satisfaction and clinical outcomes after surgery for adolescent idiopathic scoliosis in the adult (AISA) between the US and Japan.

Yagi, Mitsuru; Ames, Christopher P; Hosogane, Naobumi; Smith, Justin S; Shaffrey, Christopher I; Schwab, Frank J; Lafage, Virginie; ... (11 authors) (Journal of orthopaedic science : official journal of the Japanese Orthopaedic Association, 2023-01)

<h4>Background</h4>The impact of ethnicity on the surgery outcomes of adolescent idiopathic scoliosis in the adult (AISA) is poorly understood. This study aimed to compare the surgery outcomes for AISA between the United ...

Development of Risk Stratification Predictive Models for Cervical Deformity Surgery.

Passias, Peter G; Ahmad, Waleed; Oh, Cheongeun; Imbo, Bailey; Naessig, Sara; Pierce, Katherine; Lafage, Virginie; ... (22 authors) (Neurosurgery, 2022-12)

<h4>Background</h4>As corrective surgery for cervical deformity (CD) increases, so does the rate of complications and reoperations. To minimize suboptimal postoperative outcomes, it is important to develop a tool that allows ...

Development of predictive models for all individual questions of SRS-22R after adult spinal deformity surgery: a step toward individualized medicine.

Ames, Christopher P; Smith, Justin S; Pellisé, Ferran; Kelly, Michael; Gum, Jeffrey L; Alanay, Ahmet; Acaroğlu, Emre; ... (20 authors) (European spine journal : official publication of the European Spine Society, the European Spinal Deformity Society, and the European Section of the Cervical Spine Research Society, 2019-09)

<h4>Purpose</h4>Health-related quality of life (HRQL) instruments are essential in value-driven health care, but patients often have more specific, personal priorities when seeking surgical care. The Scoliosis Research ...

Recovery kinetics following spinal deformity correction: a comparison of isolated cervical, thoracolumbar, and combined deformity morphometries.

Passias, Peter G; Segreto, Frank A; Lafage, Renaud; Lafage, Virginie; Smith, Justin S; Line, Breton G; Scheer, Justin K; ... (23 authors) (The spine journal : official journal of the North American Spine Society, 2019-08)

BACKGROUND CONTEXT:The postoperative recovery patterns of cervical deformity patients, thoracolumbar deformity patients, and patients with combined cervical and thoracolumbar deformities, all relative to one another, is ...

Effective Prevention of Proximal Junctional Failure in Adult Spinal Deformity Surgery Requires a Combination of Surgical Implant Prophylaxis and Avoidance of Sagittal Alignment Overcorrection.
