The Use of Older Versus Newer Data in the National Surgical Quality Improvement Program Database Influences the Results of Total Hip Arthroplasty Outcomes Studies
imageIntroduction: National databases, such as the National Surgical Quality Improvement Program (NSQIP) database, are frequently used for total hip arthroplasty (THA) studies. NSQIP variables and the population included in the database have evolved over time. These changes may influence the results of studies using different periods of data. Methods: THA patients were aggregated from the 2005 to 2010 and 2011 to 2015 NSQIP data sets to define two era groups. Demographic data and 30-day perioperative outcomes were compared between the groups. As an example analysis, multivariate Poisson regression was used to determine the correlation between age and perioperative outcomes for each group. Results: Of 102,411 THA patients identified, 8098 cases were from 2005 to 2010 and 94,313 were from 2011 to 2015. A number of preoperative characteristics and perioperative outcomes were significantly different between the era groups. Multivariate analysis of the 2005 to 2010 group showed that increasing age was significantly associated with urinary tract infection and length of stay (LOS), and multivariate analysis of the 2011 to 2015 group showed that age was significantly associated with urinary tract infection, LOS, 30-day mortality, unplanned reintubation, extended LOS, pneumonia, deep vein thrombosis/thrombophlebitis, blood transfusion, and return to the operating room. Conclusion: Significantly more THA patients were enrolled in the NSQIP in the years between 2005 and 2015. Populations in 2005 to 2010 versus 2011 to 2015 were associated with differences in preoperative characteristics and perioperative outcomes. In an example analysis, it was shown that these differences together lead to different study results and conclusions. This needs to be considered when interpreting and conducting studies using earlier NSQIP data.
The Remote Completion Rate of Electronic Patient-Reported Outcome Forms Before Scheduled Clinic Visits—A Proof-of-Concept Study Using Patient-Reported Outcome Measurement Information System Computer Adaptive Test Questionnaires
imageIntroduction: Patient-Reported Outcome Measurement Information System (PROMIS) questionnaires are amenable to remote administration. This study sought to determine remote completion rates of PROMIS questionnaires before clinic visits. Methods: Patients were e-mailed a set of PROMIS forms. Completion rates were analyzed by visit type, provider seen, and patient demographics. Results: Seven hundred forty total appointments were included. Sixty-seven percent of encounters had previsit form completion. High completion rates were found for all visit types (74%, 67%, and 64% for new, return, and postoperative visits, respectively). Women had a higher completion rate than men (71% versus 64%; P = 0.031). White patients (72%; P = 0.001) and patients in the third median household income quartile ($53,725 to $83,088; 72%; P = 0.008) had higher completion rates than their respective counterparts. Conclusion: Most patients remotely completed PROMIS forms. The efficiency and accessibility of PROMIS forms may help improve ease of collection of patient-reported outcomes.
Path to Prevention of Spinal Trauma in a Low- to Middle-income Country: A Single-center Study in Phnom Penh, Cambodia
imageThis study sought to characterize the epidemiology and outcomes of spinal trauma, with or without a neurologic deficit, at a major government hospital in Phnom Penh, Cambodia. Patient demographics, American Spinal Injury Association (ASIA) score on presentation, location of injury, and cause of injury from 316 patients from September 2013 through December 2016 were compiled. Outcome measures included length of hospitalization and surgical intervention. Falls were the leading cause of spinal injury (50.6%), followed by motor vehicle accidents (29.3%) and other accidents (20.1%). Patients who fell from height had higher surgery rates (P = 0.014), and men had worse ASIA scores (P = 0.0013). Patients with ASIA A-C had a mean age of 38.17 years, whereas the D-E group was on average 42.88 years. Motor vehicle accidents caused the most cervical spine injuries, whereas falls caused more thoracic and lumbar trauma (P = 0.0005). Younger, working men are experiencing more severe spinal injuries, undergoing more surgery, and staying hospitalized longer than other demographics in Phnom Penh. This study characterizes spinal trauma from falls as a public health issue in Cambodia, highlighting the importance of fall injury prevention. Protecting this cohort is an important investment for Cambodia and necessitates workplace reform and safety standard implementation.
Slipped Capital Femoral Epiphysis in an Adult Patient With Kabuki Syndrome
imageIntroduction: Slipped capital femoral epiphysis (SCFE) is a condition which predominantly occurs in adolescents. SCFE is extremely rare in adults, and nearly all previous reported cases have been associated with an endocrine disorder. Methods: We present a case of a 19-year-old man with Kabuki syndrome who was diagnosed with an unstable SCFE requiring surgical fixation. A literature search on PubMed and Google Scholar was done looking for all published cases of delayed-onset SCFE. All previous reported cases were reviewed to determine the likely cause of the SCFE. Results: No previous cases of SCFE were described in patients with Kabuki syndrome. Literature review revealed 27 articles describing 32 cases of delayed-onset SCFE. Thirty-one of these cases were associated with endocrine disorders or pituitary tumors. Endocrine disorders associated with delayed-onset SCFE included hypothyroidism, hypogonadism, and panhypopituitarism. Pituitary adenomas and craniopharyngiomas were also associated with delayed-onset SCFE. Discussion: This is the first reported case of SCFE in a patient with Kabuki syndrome. Kabuki syndrome is a genetic disorder known to cause delayed growth, resulting in delayed physeal closure, placing the patients at risk of SCFE even into adulthood. The literature search revealed that nearly all previously described delayed-onset SCFE cases were associated with endocrine disorders or pituitary tumors. We recommend that all patients diagnosed with delayed-onset SCFE be evaluated for endocrine disorders, pituitary tumors, and/or genetic disorders which can cause delayed skeletal maturation as these disorders can range from severe endocrine disorders to intracranial tumors.
Antibiotic Impregnated Cement Dowel in a Tibial Stump to Salvage Infected Below-Knee Amputation in a Diabetic
imageCase: We describe the use of local antibiotics to salvage an infected below-knee amputation in a diabetic patient and prevent the need to convert to the above-knee level. After débridement, an antibiotic tibial “dowel” was fashioned and inserted into the intramedullary canal before closure. The wound was fully healed after four months, and the patient remained satisfied at 15 months. Conclusion: This case report offers an adjunct to the conventional management of diabetic stump infections. The addition of an antibiotic spacer could offer an alternative to a higher level of amputation and improve the survival rates of below-knee amputation in this difficult population.
Pectoralis Major Rupture in an Active Female
imagePectoralis major rupture was historically a rare occurrence, but the incidence is increasing. Most cases occur from indirect trauma in active men aged 20 to 40 years, especially during bench press. Pectoralis major rupture has never been reported in the literature in a woman in this age group. We report the first case of pectoralis major rupture in a young, active woman who underwent successful surgical fixation.
Bilateral Congenital Posterior Hemivertebrae and Lumbar Spinal Stenosis Treated With Posterior Spinal Fusion and Instrumentation
imagePosterior hemivertebrae are wedge shaped deformities that can result in progressive kyphosis. Surgical intervention at an early age may be required, however choice of surgical technique is controversial. The aim of this report was to describe a case of progressive congenital lumbar kyphosis and bilateral posterior hemivertebra with retropulsion of tissue into the spinal canal treated successfully by posterior spinal fusion and instrumentation without anterior hemivertebra resection or decompression. We report on a patient with bilateral lumbar posterior hemivertebra at L1-L2 treated with posterior spinal fusion and instrumentation at less than 1 year of age. At 10 mo of age, the patient underwent posterior spinal fusion and instrumentation with resection of L1 and L2 posterior elements. No resection of the anterior aspect of the bilateral hemivertebrae was performed. Correction of the kyphotic deformity was maintained at last radiographic follow-up at five years post-operatively and there is no evidence of spinal stenosis. Early intervention with resection of posterior elements and fusion with instrumentation for bilateral congenital lumbar hemivertebrae provided adequate deformity correction and maintenance of the spinal canal width without anterior resection. Despite his young age, instrumentation was both feasible and beneficial in maintaining alignment.
