Challenges in Pediatric Trauma: What We All Need to Know About Diaphyseal Forearm Fractures.

Diaphyseal fractures of the radius and ulna are common injuries in children and often result from a fall on an outstretched hand. Fractures are classified by completeness, angular and rotational deformity, and displacement. The goal of management is to correct the deformity to the anatomic position or within acceptable alignment parameters as defined in the literature. This is primarily achieved by closed reduction and immobilization. Greenstick fractures are reduced by rotation of the palm toward the apex of the deformity. Complete fractures are reduced with sustained traction and manipulation. All fractures are immobilized in a cast, applied with the proper molding technique to ensure adequate stabilization, and maintained until healing is evident. Follow-up radiographs should be obtained weekly during the first 3 weeks after reduction to assess loss of reduction. Generally, postreduction malalignment greater than 20° is unacceptable, but these parameters vary based on age, fracture pattern, and the location and plane of angulation. Surgical intervention, with intramedullary nailing or plate fixation, is indicated for open fractures, for those with substantial soft-tissue injury, and when acceptable alignment cannot be achieved or maintained. Successful outcomes are seen in most forearm fractures in children, based on bone healing and restoration of functional forearm range of motion.

Evaluating the effects of age on the long-term functional outcomes following anatomic total shoulder arthroplasty.

BACKGROUND: In the past decade, the number of anatomic total shoulder arthroplasty (aTSA) procedures has steadily increased. Patients over 65 years of age comprise the vast majority of recipients, and outcomes have been well documented; however, patients are opting for definitive surgical treatment at younger ages.We aim to report on the effects of age on the long-term clinical outcomes following aTSA. METHODS: Among the patients who underwent TSA, 119 shoulders were retrospectively analyzed. Preoperative and postoperative clinical outcome data were collected. Linear regression analysis (univariate and multivariate) was conducted to evaluate the associations of clinical outcomes with age. Kaplan-Meier curves and Cox regression analyses were performed to evaluate implant survival. RESULTS: At final follow-up, patients of all ages undergoing aTSA experienced significant and sustained improvements in all primary outcome measures compared with preoperative values. Based on multivariate analysis, age at the time of surgery was a significant predictor of postoperative outcomes. Excellent implant survival was observed over the course of this study, and Cox regression survival analysis indicated age and sex to not be associated with an increased risk of implant failure. CONCLUSIONS: When controlling for sex and follow-up duration, older age was associated with significantly better patient-reported outcome measures. Despite this difference, we noted no significant effects on range of motion or implant survival. Level of evidence: IV.

Hand and Upper Extremity Trauma in the Undocumented Immigrant Population in the United States.

Undocumented immigrants in the United States are at risk for upper extremity trauma due to occupational exposure, and decreased access to healthcare can worsen outcomes. The purpose of this study was to compare documented versus undocumented patients in a large cohort of patients in New York City's most diverse neighborhood in order to characterize upper extremity trauma in this population. METHODS: The Elmhurst Hospital trauma database was examined for patients admitted with upper extremity trauma from April 2016 to December 2019. Charts were examined for demographic information, documentation status, injury mechanism, and outcomes. RESULTS: Of the 1041 patients included, 865 (83.1%) were documented and 176 (16.9%) were undocumented. Undocumented immigrants were younger (40.5 versus 62.4 years, P < 0.0001) and predominantly men (83.5% versus 57.1%, P < 0.0001) with fewer comorbidities (42.6% versus 64.6%, P < 0.0001). Occupational injury was three times as likely in undocumented immigrants (13.6% versus 4.6%, P < 0.0001) and these patients were nearly twice as likely to be harmed from violence (19.9% versus 10.2%, P = 0.0003). Increased rates of injury during bicycle/motorcycle accidents (8.0% versus 3.0%, P = 0.0017) or being struck as a pedestrian (21.6% versus 14.3%, P = 0.0149) were found in the undocumented cohort, with falls (39.8% versus 59.3%, P < 0.0001) or vehicle collisions (0.6% versus 3.5%, P = 0.0402). CONCLUSIONS: Undocumented patients with upper extremity trauma represent a younger/healthier cohort, but are more likely to be injured at work or by violence. Documentation status plays a role in injury characteristics.

Treatment patterns and failure rates associated with prosthetic joint infection in unicompartmental knee arthroplasty: A systematic review.

Background: Prosthetic joint infection (PJI) following unicompartmental knee arthroplasty (UKA) is a rare but challenging complication. A paucity of literature exists regarding the management of PJI in UKA. This systematic review aims to assess current treatment patterns in UKA PJI and analyze the failure rates associated with treatment. Methods: PubMed, Scopus, and EMBASE were systematically searched for studies that presented cases of PJI following UKA. Data regarding study design, country of publication, index procedure type, diagnosis of PJI, number and incidence of PJI, timing of PJI (acute versus chronic), treatment, and outcomes were recorded. Failure rates in acute and chronic PJI as well as total failure rates were analyzed. Results: Sixteen articles were identified that met inclusion criteria. These included 97 PJI cases (37 acute, 58 chronic, 2 unknown timing); incidence across all studies of 0.80%. The most common treatment for all PJI cases was debridement, antibiotics, and implant retention (DAIR) (40.2%), followed by two-stage conversion to total knee arthroplasty (TKA) (33.0%), one-stage conversion to TKA (23.7%), and one-stage exchange UKA (3.1%). There were no significant differences in failure rates across procedures for acute, chronic or overall PJI management (p > 0.05 for all). Conclusion: This systematic review found relatively few studies reporting on PJI after UKA compared to the available TKA evidence. Further research is warranted to better elucidate the most appropriate treatment of PJI after UKA in both the acute and chronic setting along with risk factors for failure.
