Abstract Background Percutaneous pinning fixation (PCP) has been used for the treatment of distal radius fractures for decades, especially in the elderly with fragile soft tissue. However, achieving and maintaining a sound anatomic reduction before PCP is difficult if we use the manipulative reduction method alone. Our study innovatively applied the Steinmann pin retractor for closed reduction combined with PCP, to provide a new protocol for the treatment of distal radius fractures. Methods From March 2017 to July 2018, 49 patients out of 57 that met the inclusion criteria but not the exclusion criteria were included in our retrospective cohort study. Sixteen patients were treated with Steinmann pin retractor-assisted closed reduction combined with PCP (S-PCP), and 19 patients were treated with the manipulative reduction combined with PCP (M-PCP), and 14 patients were treated with the manipulative reduction combined with cast splint (M-C). All these patients received a positive postoperative radiological and clinical evaluation. Results All the patients were followed up for a minimum of 2 years. The radiological parameters in each group improved significantly postoperative (posttreatment). In the S-PCP group, the values of radial height (postoperative, 13.33±1.74 mm; the first follow-up, 13.27±1.81mm; last follow-up, 13.16±1.76mm) and ulnar variance (postoperative, −0.10±1.29mm; the first follow-up, −0.05±1.27mm; last follow-up, −0.12±1.09mm) significantly improved as compared to the M-PCP and M-C groups. While the patients in the M-C group experienced significant re-displacement at the first and last follow-ups, in the S-PCP group, the range of wrist motion including extension (89.94±5.21%), radial deviation (90.69±6.01%), and supination (90.25±5.87%); ulnar deviation (89.81±5.82%) and QuickDASH score (2.70±3.64); and grip strength (92.50±5.59%), pronation (90.50±6.04%), and modified Mayo wrist score (90.94±4.17, the excellent rate reached up to 75%) also improved as compared to the M-PCP group, M-C group, or both groups at the last follow-up. Conclusion S-PCP improves fracture reduction and wrist function and can serve as an effective method for A2(AO/OTA) and A3 type of distal radius fractures in the elderly with limited dorsal comminution, including intra-articular fractures with displacement less than 2mm.

Adverse Perinatal Outcomes

Abstract Background Racial disparities in adverse perinatal outcomes have been studied in other countries, but little has been done for the Canadian population. In this study, we sought to examine the disparities in adverse perinatal outcomes between Asians and Caucasians in Ontario, Canada. Methods We conducted a population-based retrospective cohort study that included all Asian and Caucasian women who attended a prenatal screening and resulted in a singleton birth in an Ontario hospital (April 1st, 2015-March 31st, 2017). Generalized estimating equation models were used to estimate the independent adjusted relative risks and adjusted risk difference of adverse perinatal outcomes for Asians compared with Caucasians. Results Among 237,293 eligible women, 31% were Asian and 69% were Caucasian. Asians were at an increased risk of gestational diabetes mellitus, placental previa, early preterm birth (< 32 weeks), preterm birth, emergency cesarean section, 3rd and 4th degree perineal tears, low birth weight (< 2500 g, < 1500 g), small-for-gestational-age (<10th percentile, <3rd percentile), neonatal intensive care unit admission, and hyperbilirubinemia requiring treatment, but had lower risks of preeclampsia, macrosomia (birth weight > 4000 g), large-for-gestational-age neonates, 5-min Apgar score < 7, and arterial cord pH ≤7.1, as compared with Caucasians. No difference in risk of elective cesarean section was observed between Asians and Caucasians. Conclusion There are significant differences in several adverse perinatal outcomes between Asians and Caucasians. These differences should be taken into consideration for clinical practices due to the large Asian population in Canada.

Background: Owing to the many unique disease characteristics of Parkinson disease (PD)—namely resting tremors, muscular rigidity, and poor bone quality—we hypothesized that this patient population would have inferior outcomes with surgical management of acute distal radius fractures (DRFs) compared with the literature available on the general population. Methods: This is a retrospective observational study performed at a single, level 1, academic center from 2001 to 2020 capturing all adult patients with an isolated, acute, and closed DRF that ultimately underwent operative treatment. International Classification of Diseases 10 codes were used to identify 30 patients for manual chart review. Several patient and fracture characteristics were accounted for and complications, reoperations, and failures of surgical intervention were recorded. Results: There was a total of 7/30 failures (23%), 6/30 reoperations (20%), and 12 complications in 9/30 wrists (complication rate, 30%) at a mean latest follow-up of 11 months (1.2-158 months). Of the 7 failures, 5 were due to loss of reduction, and 2 of them were deep infections with mean time to failure of 8.3 weeks (range, 11 days-5.2 months). Conclusions: This study found a high rate of complications, reoperations, and early failure despite a short follow-up period and a small cohort of patients with PD treated surgically for a DRF. We recommend locked plating if suitable for the fracture type and early involvement of a multidisciplinary team to assist with medical optimization of PD to increase chances of a successful outcome.
