Infection Rate in Type I Open Distal Radius Fractures Surgically Treated >24 Hours Post-Injury: A Comparison Study.

PURPOSE: To determine how time to surgical debridement and fixation affects infection and complication rate in type I open distal radius fractures by comparing patients treated within 24 hours with those treated >24 hours post-injury. METHODS: A retrospective review identified 62 patients who sustained a type I open distal radius fracture that was treated surgically. Patients were stratified into groups based on time to surgical intervention. An additional analysis was performed on patients with an isolated type I open distal radius fracture treated as an inpatient or outpatient. The primary outcome measure was infection rate. Secondary outcome measures were complications, reoperations, and readmissions. RESULTS: Thirty-eight patients underwent surgery ≤24 hours post-injury at an average of 14 hours. Twenty-four patients underwent surgery >24 hours post-injury at an average of 72 hours. There were a total of 9 complications in 8 patients (14.5%). The overall infection rate was 1.6%, with only 1 deep infection occurring in the group treated ≤24 hours post-injury. There were 7 reoperations (11.3%) and 1 readmission (1.6%). No differences were found between groups in any outcome measure. In the 27 patients with an isolated fracture, there were no differences in any outcome measure when treated as an inpatient or outpatient. CONCLUSIONS: We suggest that type I open distal radius fractures could be safely treated surgically >24 hours post-injury without increased risk of infection.

Periarticular screws: what's in and what's out of the joint?

Periarticular hardware placement can be challenging and a source of angst for orthopaedic surgeons due to fear of penetrating the articular surface and causing undue harm to the joint. In recent years, many surgeons have turned to computed tomography (CT) and other intraoperative or postoperative modalities to determine whether hardware is truly extraarticular in areas of complex anatomy. Yet, these adjuncts are expensive, time consuming, and often unnecessary given the advancement in understanding of intraoperative fluoroscopy. We present a review article with the goal of empowering surgeons to leave the operating room, with fluoroscopy alone, assured that all hardware is beneath the articular surface that is being worked on. By understanding a simple concept, surgeons can extrapolate the information in this article to any joint and bony surface in the body. While targeted at both residents and surgeons who may not have completed a trauma fellowship, this review can benefit all orthopaedic surgeons alike.

Predicting Pathologic Bone Lesions Using Scout Computed Tomography (CT) Imaging.

The purpose of this study is to evaluate the benefit of reviewing scout CT images, obtained for routine oncologic surveillance, for the early identification of pathologic bony lesions. A retrospective review was conducted on patients who previously underwent surgical treatment by two orthopedic oncology surgeons at a tertiary care institution from 2009-2019 for pathologic lesions or fractures of the humerus or femur. Radiographic records were reviewed to identify patients in this cohort who had available scout views from CT imaging prior to official diagnosis of the bony lesion or fracture. CT scout images were assessed by two independent reviewers to identify any pathologic lesions, and radiographic reports were reviewed to identify if the lesions were noted by radiology at the time of the initial scan interpretation. One hundred and forty-four patients were identified, and thirty-nine had an available scout CT image prior to official diagnosis of the lesion. Twenty-five patients (64.1%) had lesions identified by authors on scout CT versus only 9 (23.1%) who had lesions that were documented in the initial CT radiologic report. There was a total of 29 lesions identified by the study authors on scout CT, and 19 (65.5%) were not reported in the initial radiographic interpretation with an average interval between observation by authors and official diagnosis of 202 days. Of the impending fractures, three patients (16.7%) went on to complete fracture prior to referral to orthopedics with an average interval between these missed lesions on scout CT and their presentation with fracture of 68 days. This study advocates for the careful review of all scout CT imaging as an essential part of the work up for metastatic disease and encourages all practitioners to utilize this screening tool for the identification of pathologic bony lesions which may help expedite early treatment to reduce patient morbidity.

Intramedullary Nail Fixation for the Treatment of Pathologic Humeral Shaft Fractures.

The goal of this study was to report the clinical outcomes of pathologic humeral shaft fractures treated with reamed or unreamed intramedullary nail fixation in an era of longer patient survival. A retrospective review was conducted of all patients who underwent intramedullary nail fixation performed by a single surgeon for pathologic humeral shaft fractures at a Level I trauma center from 2009 to 2017. Of the 25 patients who were identified, 9 were excluded. Groups were categorized according to whether they underwent reamed or unreamed fixation, and they were evaluated for evidence of union, complications, and reoperation. Of the patients, 11 underwent an unreamed procedure and 5 underwent a reamed procedure. Mean length of follow-up was 51.5 weeks. Of the patients who participated, 12 (75%) showed evidence of union and 2 patients (12.5%) showed evidence of nonunion, with no statistical difference between the groups. Five patients (31.3%) had complications. One nonunion occurred in the reamed group and did not require reoperation. In the unreamed group, complications consisted of 1 delayed union, 1 nonunion treated with revision intramedullary nail fixation, and 2 cases of disease progression that required reoperation. Intramedullary nail fixation of pathologic humeral shaft fractures achieves rates of union parallel to those seen with fixation in a healthy population. The length of follow-up in the current study was longer than the life expectancy reported by previous authors, which can be attributed to improvements in the treatment of cancer. The current authors argue that unreamed fixation is the optimal technique because it yields similar outcomes to a reamed approach and is faster and potentially safer.

Pharmacological thrombolysis for acute ischemic stroke treatment: Gender differences in clinical risk factors.

BACKGROUND: In a stroke population, women have a worse outcome than men when untreated. In contrast, there is no significant difference in treated patients. In this study, we determined whether clinical variables represent a promising approach to assist in the evaluation of gender differences in a stroke population. METHODS: We analyzed data from ischemic stroke patients' ≥18 years-old from the stroke registry on rtPA administration and identified gender differences in clinical factors within inclusion and exclusion criteria in a stroke population that received rtPA. Multivariate analysis was used to adjust for patient demographic and clinical variables. RESULTS: Of the 241 eligible stroke patients' thrombolytic therapy, 49.4% were females and 50.6% were males. Of the 422 patients that did not receive rtPA, more women (235) were excluded from rtPA than men (187) (P<0.05). In the male population, exclusion from rtPA was associated with history of a previous stroke (P<0.05, OR=2.028), hypertension (P<0.05, OR=0.519), and NIH stroke score (P<0.0001, OR=0.893). In female stroke patients, exclusion from rtPA was associated with previous history of stroke (P<0.05, OR=2.332), diabetes (P<0.05, OR=1.88) and NIH stroke score (P<0.05, OR=0.916). CONCLUSIONS: Despite similarities in different areas of stroke care for both men and women, more women with diabetes, previous history of stroke and higher NIH scores are more likely to be excluded from thrombolytic therapy. Men with a previous history of stroke, hypertension and higher NIH scores are more likely to be excluded rtPA even after adjustment for confounding variables.
