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)
STUDY DESIGN A retrospective study of prospectively collected data. OBJECTIVE The aim of this study was to identify risk factors in developing hospital-acquired conditions (HACs) and association of HACs with other 30-day complications in the adult spinal deformity (ASD) population. SUMMARY OF BACKGROUND DATA HACs are subject to a nonpayment policy by(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)
STUDY DESIGN Retrospective study of prospectively collected data. OBJECTIVE To investigate the applicability of the modified frailty index (mFI) as a predictor of adverse postoperative events in patients undergoing anterior cervical discectomy and fusion (ACDF) or posterior cervical fusion (PCF). SUMMARY OF BACKGROUND DATA Prior studies have(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)
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)
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 Retrospective study of prospectively collected data. OBJECTIVE To determine if postoperative morbidity for patients undergoing spinal deformity surgery varies by sex. SUMMARY OF BACKGROUND DATA Influence of sex has been investigated in other surgical procedures but has not yet been studied in adult spinal deformity surgery. METHODS The(More)
PURPOSE OF REVIEW Cervical disc replacement (CDR) is a surgical option for appropriately indicated patients, and high success rates have been reported in the literature. Complications and failures are often associated with patient indications or technical variables, and the goal of this review is to assist surgeons in understanding these factors. RECENT(More)
