BACKGROUND Lumbar discectomy and laminectomy in patients with intervertebral disc herniation (IDH) is common, with variable reported reoperation rates. Our study examined which baseline characteristics might be risk factors for reoperation and compared outcomes between patients who underwent reoperation and those who did not. METHODS We performed a(More)
STUDY DESIGN A retrospective subgroup analysis was performed on surgically treated patients from the lumbar spinal stenosis (SpS) arm of the Spine Patient Outcomes Research Trial (SPORT), randomized, and observational cohorts. OBJECTIVE To identify risk factors for reoperation in patients treated surgically for SpS and compare outcomes between patients(More)
Metacarpal fractures are common, especially in men, and account for about 10% of all fractures in patients. The fracture pattern and location, and the degree of angulation are important in determining the optimal treatment approach. Although metacarpal fractures can be treated nonsurgically, certain indications such as irreducible fractures, malrotations,(More)
A pilot study of the effect of exogenous surfactant (ES) on premature infants with respiratory distress syndrome (RDS) is reported. Each of the first 15 infants in this study received 200 mg/kg of natural surfactant (Curosurf) during the first day of life. Controls were 56 infants with RDS seen in the 15 months prior to the study. Within 5 minutes of(More)
STUDY DESIGN A retrospective study of prospectively collected data. OBJECTIVE The aim of this study was to determine whether patients undergoing spinal deformity surgery with resident involvement are at an increased risk of morbidity. SUMMARY OF BACKGROUND DATA Resident involvement has been investigated in other orthopedic procedures but has not been(More)
STUDY DESIGN Retrospective study of prospectively collected data. OBJECTIVE To determine if patients undergoing spinal deformity surgery with pelvic fixation are at an increased risk of morbidity. METHODS The American College of Surgeons National Surgical Quality Improvement Program is a large multicenter clinical registry that prospectively collects(More)
STUDY DESIGN Retrospective analysis of prospective data from the degenerative spondylolisthesis (DS) arm of the Spine Patient Outcomes Research Trial. OBJECTIVE To identify risk factors for reoperation in patients treated surgically for DS and compare outcomes between patients who underwent reoperation with non-reoperative patients. SUMMARY OF(More)
Septic arthritis is a devastating condition; well-established criteria for diagnosis exist in the pediatric population, but not for adults. This study evaluated patient factors and laboratory parameters that may be associated with the diagnosis of septic arthritis in adults. A total of 458 knee aspirates for suspected septic arthritis were evaluated with(More)
BACKGROUND CONTEXT Prior studies have suggested no significant differences in functional status and postoperative complications of elderly versus nonelderly patients undergoing posterior lumbar interbody fusion; however, similar studies have not been comprehensively investigated in the setting of anterior lumbar interbody fusion (ALIF). PURPOSE The(More)
BACKGROUND CONTEXT Brown-Séquard syndrome is characterized by a hemisection of the spinal cord most commonly after spinal trauma or neoplastic disease. The injury causes ipsilateral hemiplegia and proprioceptive sensory disturbances with contralateral loss of pain and temperature sensation. Patients with Brown-Séquard syndrome have the best prognosis of all(More)
