The impact of lumbar alignment targets on mechanical complications after adult lumbar scoliosis surgery.

Purpose: The purpose of this study was to determine the discriminatory ability of age-adjusted alignment offset and the global alignment and proportion (GAP) score parameters to predict postoperative mechanical complications.

Methods: Surgical patients from the Adult Symptomatic Lumbar Scoliosis cohort were reviewed at 2 year follow up. Age-adjusted alignment offsets and GAP parameters were calculated for each patient.

Treatment Outcomes in Spinal Metastatic Disease With Indeterminate Stability.

Study Design: Retrospective cohort study.

Objective: The purpose of this study was to compare outcomes between different treatment modalities for metastatic disease with indeterminate instability (Spinal Instability Neoplastic Score [SINS] 7-12).

Methods: We retrospectively reviewed neurologically intact patients treated for spinal metastatic disease with a SINS of 7 to 12.

Implant Distribution Versus Implant Density in Lenke Type 1 Adolescent Idiopathic Scoliosis: Does the Position of the Screw Matter?

Study Design: Retrospective study.

Objective: Previous studies have demonstrated that increased implant density (ID) results in improved coronal deformity correction. However, low-density constructs with strategically placed fixation points may achieve similar coronal correction.

Staying ahead of the curve: the use of spinopelvic parameters to predict curve progression and bracing success in adolescent idiopathic scoliosis.

Study Design: Retrospective cohort study.

Objectives: To investigate radiographic sagittal and spinopelvic parameters of patients with adolescent idiopathic scoliosis (AIS) treated with bracing and assess differences among those treated successfully and unsuccessfully. AIS is a three-dimensional deformity of the spine, sharing an intricate relationship with pelvic morphology.

Factors Associated With Extended Length of Stay and 90-Day Readmission Rates Following ACDF.

Study Design: Retrospective.

Objective: Identify patient risk factors for extended length of stay (LOS) and 90-day hospital readmissions following elective anterior cervical discectomy and fusion (ACDF).

Methods: Included ACDF patients from 2013 to 2017 at a single institution.

Does facility volume influence survival in patients with primary malignant bone tumors of the vertebral column? A comparative cohort study.

Background Context: Facility volume has been correlated with survival in many cancers. This relationship has not been established in primary malignant bone tumors of the vertebral column (BTVC).

Purpose: To investigate whether facility patient volume is associated with overall survival in patients with primary malignant BTVCs.

The Role of Radiotherapy for Chordoma Patients Managed With Surgery: Analysis of the National Cancer Database.

Study Design: Retrospective review.

Objective: To determine if adjuvant radiation therapy (RT) improves overall survival (OS) following surgical resection of chordomas.

Summary Of Background Data: The role of RT for the treatment of chordomas remains incompletely described.

Revisiting the Role of Radiation Therapy in Chondrosarcoma: A National Cancer Database Study.

Background: Although chondrosarcomas (CS) are mostly considered radioresistant, advancements in radiotherapy have brought attention to its use in these patients. Using the largest registry of primary bone tumors, the National Cancer Database (NCDB), we sought to better characterize the current use of radiotherapy in CS patients and identify any potential survival benefit with higher radiation doses and advanced radiation therapies.

Methods: We retrospectively analyzed CS patients in the NCDB from 2004 to 2015 who underwent radiotherapy.

Complications After Pediatric Hip Fractures: Evaluation and Management.

Pediatric proximal femur fractures are high-energy injuries with predictable and morbid complications. Osteonecrosis of the femoral head is the most common complication with identified risk factors including fracture type, patient's age, degree of displacement, timing to reduction, and stability of fixation. Additional complications include nonunion, coxa vara, and premature physeal arrest.

Periapical Wires Result in Less Curve Correction Than Pedicle Screw Constructs in Idiopathic Scoliosis.

Study Design: Retrospective study.

Purpose: The objective of this study was to compare percent correction between apical and periapical pedicle screw (PS) and sublaminar wire constructs for Cobb correction and coronal balance correction.

Overview Of Literature: The current gold standard for deformity correction in adolescent idiopathic scoliosis (AIS) are PS constructs.

Epidemiologic and survival trends in adult primary bone tumors of the spine.

Background Context: Malignant primary spinal tumors are rare making it difficult to perform large studies comparing epidemiologic, survival, and treatment trends. We investigated the largest registry of primary bone tumors, the National Cancer Database (NCDB), to compare epidemiologic and survival trends among these tumors.

Purpose: To use the NCDB to describe current epidemiologic trends, treatment modalities, and overall survival rates in patients with chordomas, osteosarcomas, chondrosarcomas, and Ewing sarcomas of the mobile spine.

Pediatric proximal femur fractures.

Pediatric proximal femur fractures are rare injuries resulting from high-energy trauma. The Delbet classification is used when describing these injuries, and associates fracture type to the development of avascular necrosis. Historically, casting was utilized in the treatment of these injuries, but high complication rates following this approach have changed the treatment modality to early and anatomic fixation.

Intrawound Vancomycin Powder in Primary Total Hip Arthroplasty Increases Rate of Sterile Wound Complications.

Purpose: Total hip arthroplasty (THA) is a successful surgery for the treatment of hip osteoarthritis; however, the risk of a post-operative prosthetic joint infection (PJI) remains at 1% to 2%. The purpose of this study was to investigate the safety profile of using vancomycin powder (VP) to reduce infection rates by reviewing acute postoperative complications.

Materials And Methods: A retrospective review of 265 consecutive patients undergoing THA was performed.
