Canal Fill of the Forearm Bones When Placing Intramedullary Nails in the Pediatric and Adolescent Populations.

BACKGROUND: In the lower extremity, studies have suggested an optimal nail diameter to medullary canal diameter (ND/MCD) ratio to minimize postoperative complications. The goal of this study was to determine whether a correlation exists between the occurrence of complications, angulation, and range of motion and the ratio of the ND/MCD in the upper extremity. METHODS: A total of 85 radius and ulna fractures treated with flexible intramedullary nails had ND/MCD ratios measured. Random-effects models were developed to determine the association between complications and ND/MCD ratio, angulation and ND/MCD ratio, and range of motion and ND/MCD ratio. The results were reported for unadjusted models and adjusted models. RESULTS: Of the 85 forearm fractures treated with intramedullary nailing, there were 3 complications. The average follow-up was 6 months. The ND/MCD ratios were categorized as <0.50, 0.50 to 0.59, and ≥0.60. There was not a significant association between the different ratios and angulation, or risk of complication. There was an association between the ND/MCD ratio ≥0.60 and decreased pronation of -1.58° (-2.77° to -0.38°) and supination of -2.68° (-4.91° to -0.46°) (P < .05). CONCLUSION: This study found that there was not an association between the nail to canal diameter ratio and postoperative angulation in forearm fractures treated with flexible intramedullary nails. When choosing a flexible nail for forearm fractures, there does not appear to be an optimal ratio; it is therefore reasonable to use the ND that passes more easily.

Discharge Opioid Prescribing Patterns in an Academic Orthopaedic Setting: Level of Training and Subspecialty Patterns.

INTRODUCTION: Despite increased research on opioids in the orthopaedic literature, little is known of the prescribing practices of orthopaedic providers based on their level of training. The purpose of this study was to describe the discharge opioid prescribing patterns of orthopaedic providers, stratifying by level of training and orthopaedic subspecialty, within a single medical system. METHODS: A retrospective review of orthopaedic surgical encounters was performed over a 1-year period for adults who received a discharge opioid prescription. Patient demographics and prescriber characteristics were collected, including the provider's level of training (attending, fellow, resident, physician assistant [PA], and nurse practitioner [NP]) and surgical subspecialty. Junior residents were postgraduate year 1 to 3, whereas senior residents/fellows were postgraduate year 4 to 6. Discharge opioids were converted to milligram morphine equivalents (MMEs). Overprescribing was defined as a prescribing more than a seven-day supply or >45 MMEs per day. Multivariable linear regression analysis determined the factors associated with discharge MMEs, whereas logistic regression determined the factors associated with overprescribing opioids. RESULTS: Of the 3,786 patients reviewed, 1,500 met the criteria for inclusion in the study. The greatest proportion of opioid prescriptions was written by junior residents (33.9%), followed by NPs (30.1%), PAs (24.1%), senior residents/fellows (10.6%), and attendings (1.2%). Compared with junior residents, senior residents prescribed -59.4 MMEs, NPs prescribed +104 MMEs, and attendings prescribed +168 MMEs (P < 0.05), whereas PAs prescribed similar amounts (P > 0.05). Orthopaedic subspecialty was also predictive of discharge MMEs (P < 0.05). Senior residents and attendings were more likely to prescribe more than seven days of opioids (P < 0.05), whereas NPs and PAs were more likely to prescribe >45 MMEs per day (P < 0.05). DISCUSSION: This study demonstrates significant variability in opioid prescribing practices according to provider level of training and subspecialty. National guidelines for opioid prescribing practices and educational programs may help reduce such variability. LEVEL OF EVIDENCE: Level III, retrospective cohort study.

Upper Extremity Compressive Neuropathies in the Pediatric and Adolescent Populations.

PURPOSE OF REVIEW: Although somewhat rare, upper extremity compressive neuropathies can occur in the pediatric and adolescent populations due to various etiologies. Some of the most common conditions seen include thoracic outlet syndrome, supracondylar process syndrome, cubital tunnel syndrome with subluxation of the ulnar nerve, and carpal tunnel syndrome. This review will focus on these diagnoses and how to address them in the pediatric and adolescent populations. RECENT FINDINGS: Due to the rarity of upper extremity compressive neuropathies in the pediatric and adolescent populations, substantial advancement in the literature does not routinely occur. However, recent literature has found a difference in the rate of various subtypes of thoracic outlet syndrome in children versus adults. Additionally, cubital tunnel syndrome associated with ulnar nerve subluxation/instability has recently been found to have better outcomes following surgical decompression of the ulnar nerve and transposition than those with stable ulnar nerves. In summary, this review provides the most recent knowledge surrounding upper extremity compressive and entrapment neuropathies in the pediatric and adolescent populations.
