Abstract Background The femur is the most common site of metastasis in appendicular skeleton, and metastatic bone disease negatively influences quality life. Orthopaedic surgeons are often faced with deciding whether to prophylactically stabilize an impending fracture, it unclear if prophylactic fixation increases likelihood survival. Questions/purposes Is stabilization patients associated different overall survival than a complete pathologic fracture? Methods We performed retrospective,...
Study Design: Retrospective cross-sectional study aimed to investigate the postoperative outcomes following anterior cervical discectomy and fusion (ACDF) surgery in patients with end-stage renal disease (ESRD) transplant recipients, using data from a large national database. Three patient groups were analyzed: control group, ESRD group. Objective: To ACDF utilizing Background: Patients recipients face unique health challenges, there is paucity of comprehensive research examining their...
Cervical artificial disc replacement (C-ADR) has become a common and accepted surgical treatment for many patients with cervical degeneration/herniation radiculopathy who have failed nonoperative treatment. Midterm follow-up studies of the original investigational device exemption trials comparing C-ADR to traditional anterior discectomy fusion (ACDF) revealed less adjacent-level disease fewer reoperations at 5 7 years. The purpose this study was examine relationship radiographic (R-ALD)...
Study Design. Retrospective study. Summary of Background Data. Research has shown that the use NSAIDs and COX-2 inhibitors increases risk pseudoarthrosis following spinal fusion surgery. Pseudoarthrosis can lead to complications such as chronic pain need for additional surgeries. Objective. The purpose this study was examine relationship between NSAID inhibitor pseudarthrosis, hardware complications, revision surgeries in patients undergoing posterior instrumentation fusion. Methods. We...
Vitamin D has been shown to play important roles in both calcium homeostasis and bone healing. Only three studies have directly examined the relationship between vitamin deficiency hardware failure, nonunion, and/or revision surgery. Results are contradictory none were large enough provide statistical power necessary make definitive conclusions.A retrospective analysis was performed utilizing PearlDiver national insurance claims database consisting of 91 million individual patient records....
In patients with concomitant hip and lumbar spine disease, the question of which surgery-total arthroplasty (THA) or fusion (LSF)-to address first has not been adequately answered. We aimed to evaluate risk dislocation after THA in LSF THA.Retrospective review utilizing PearlDiver database querying Current Procedural Terminology codes for year prior (LSF first) primary revision (THA first). International Classification Disease identified postoperative as our outcome variable. Demographic...
A retrospective data collection study with application of metastatic spine scoring systems.To apply the Tomita and revised Tokuhashi systems to a surgical cohort at single academic institution analyze spine-related morbidity mortality rates.Surgical management patients requires tools that can accurately predict patient survival, as well knowledge rates.An Oregon Health & Science University (OHSU) Spine Center database was queried (years 2002-2010) identify an ICD-9 code indicative disease....
Metastatic bone disease affects approximately 300,000 people in the United States, and burden is rising. These patients experience significant morbidity decreased survival. The management of these requires coordinated care among a multidisciplinary team physicians, including orthopaedic surgeons. This article reviews role radiation therapy after stabilization impending or realized pathologic extremity fractures. Orthopaedic surgeons have an opportunity to benefit with metastatic by referring...
<h3>Background</h3> Surgical treatment of vertebral osteomyelitis, discitis, and epidural abscesses is indicated in the setting failure antibiotic therapy, neurological deficits, abscess, or spinal instability/deformity. Historically, surgical mandated aggressive debridement stabilization. However, there growing evidence that direct may not be necessary contribute to morbidity. The purpose this study was evaluate efficacy posterior instrumentation without treating infections....
The purpose of this study is to examine the utilization kyphoplasty/vertebroplasty procedures in management compression fractures. With growing elderly population and associated increase rates osteoporosis, vertebral fractures have become a daily encounter for spine surgeons. However, there remains lack consensus on optimal patient population.
Study Design Retrospective Cohort Study. Objective To identify risk factors for sacroiliac (SI) joint fusion after instrumented spinal fusion. Methods Patients were identified from the PearlDiver BiscayneBay database. who underwent 1 level (CPT: 22840), 3-6 vertebral segment (22842), and 7+ fusions (22843 22844) identified. separated based on whether they received an SI (27280 27279) their A univariate analysis multivariate logistic regression was performed to evaluate associations between...
A 71-year-old man with a history of C5-7 anterior cervical discectomy and fusion (ACDF) sustained C7 spinous process fracture after falling from ladder. He was initially managed nonoperatively but developed anterolisthesis kyphosis at C7-T1 left hand weakness over the course 11 days. Surgical treatment included wiring C5-T3 posterior fusion. At 14-month follow-up, he demonstrated resolution pain returned motor function.
Abstract Introduction Interspinous process devices (IPDs) were developed as minimally invasive alternatives to open decompression surgery for spinal stenosis. However, given high treatment failure and reoperation rates, there has been minimal adoption by spine surgeons. This study leveraged a national claims database characterize IPD usage patterns postoperative outcomes after implantation. Method Using the PearlDiver database, we identified all patients who underwent 1- or 2-level...
