case report and literature review anterior shoulder dislocation with three part proximal humerus fracture and Humeral Shaft fracture
The Iowa orthopaedic journal, 2009Co-Authors: John H Flint, Laura M Carlyle, Cory C Christiansen, James V NepolaAbstract:Dislocation of the shoulder and proximal humerus fracture with coexistent Humeral Shaft fracture is a rare injury reported in literature. There have been a total of 20 cases reported in the literature since 19401-13 (see Table 1). These injuries often occur as a result of high velocity trauma and most have been treated, at least partially, with invasive or operative management. We present the case of a woman with an anterior dislocation, three-part proximal humerus fracture and concomitant humerus Shaft fracture and discuss her non-invasive treatment.

early post operative outcomes of plate versus nail fixation for Humeral Shaft fractures
Injury-international Journal of The Care of The Injured, 2019Co-Authors: Jill G Putnam, Emil H. Schemitsch, Lauren L Nowak, David W Sanders, Melanie Macnevin, Abdel Rahman Lawendy, Clifford B Jones, Michael D MckeeAbstract:Abstract Introduction This study was designed to measure early postoperative outcomes of plate vs. nail fixation for Humeral Shaft fractures. Patients and methods Patients ≥18 years who underwent plate or nail fixation for low-energy Humeral Shaft fractures between 2005–2016 were identified from the National Surgical Quality Improvement Program (NSQIP). Multivariable regression was used to compare postoperative outcomes using propensity score adjustment to account for differences between fixation groups. Variables included in the propensity score were age, American Society of Anesthesiologists (ASA) class, hypertension, steroid use, cancer, functional status, chronic obstructive pulmonary disease (COPD), congestive heart failure (CHF), and sex. Results Plate fixation was used in 1418 patients (70.6%), while nail fixation was used in 591 (29.4%). Patients undergoing nail fixation were more likely to be older, have a higher American Society of Anesthesiologists (ASA) class, and have comorbidities. Mean operative time was statistically longer in the plate fixation group (130 +/−62 min vs. 102 +/−54 min). After propensity score adjustment, type of fixation was not a significant predictor of major or minor complications, length of stay, or readmission. However, nail fixation was a significant predictor of mortality following propensity score adjustment (OR 3.15, 95% Confidence interval 1.26–7.85). Conclusion Patients undergoing intramedullary nail fixation tended to be older patients with more comorbidities, suggesting that surgeons are selecting nail fixation in patients who may not be ideal surgical candidates. Although LOS, complications, and readmission rates were higher in the nail group, this difference was not statistically significant following propensity score adjustment. However, nail fixation remained an independent predictor of 30-day mortality following adjustment. This suggests that nail fixation may not be a safer surgical option in patients with multiple medical co-morbidities and low-energy Humeral Shaft fractures.

the biomechanical effect of torsion on Humeral Shaft repair techniques for completed pathological fractures
Journal of Biomechanical Engineering-transactions of The Asme, 2012Co-Authors: Ahmed Aljahwari, Emil H. Schemitsch, Jay S Wunder, Peter C Ferguson, Radovan ZderoAbstract:In the presence of a tumor defect, completed Humeral Shaft fractures continue to be a major surgical challenge since there is no "gold standard" treatment. This is due, in part, to the fact that only one prior biomechanical study exists on the matter, but which only compared 2 repair methods. The current authors measured the Humeral torsional performance of 5 fixation constructs for completed pathological fractures. In 40 artificial humeri, a 2-cm hemi-cylindrical cortical defect with a transverse fracture was created in the lateral cortex. Specimens were divided into 5 different constructs and tested in torsion. Construct A was a broad 10-hole 4.5-mm dynamic compression plate (DCP). Construct B was the same as A except that the screw holes and the tumor defect were filled with bone cement and the screws were inserted into soft cement. Construct C was the same as A except that the canal and tumor defect were filled with bone cement and the screws were inserted into dry cement. Construct D was a locked intramedullary nail inserted in the antegrade direction. Construct E was the same as D except that bone cement filled the defect. For torsional stiffness, construct C (4.45 ± 0.20 Nm/deg) was not different than B or E (p > 0.16), but was higher than A and D (p < 0.001). For failure torque, construct C achieved a higher failure torque (69.65 ± 5.35 Nm) than other groups (p < 0.001). For the failure angle, there were no differences between plating constructs A to C (p ≥ 0.11), except for B versus C (p < 0.05), or between nailing groups D versus E (p = 0.97), however, all plating groups had smaller failure angles than both nailing groups (p < 0.05). For failure energy, construct C (17.97 ± 3.59 J) had a higher value than other groups (p < 0.005), except for A (p = 0.057). Torsional failure always occurred in the bone in the classic "spiral" pattern. Construct C provided the highest torsional stability for a completed pathological Humeral Shaft fracture.

compression plating versus intramedullary nailing of Humeral Shaft fractures a meta analysis
Acta Orthopaedica, 2006Co-Authors: Mohit Bhandari, P J Devereaux, Emil H. SchemitschAbstract:Background The choice of plates or intramedullary nails for operatively treated Humeral Shaft fractures remains controversial, since randomized controlled trials have lacked sufficient power. A meta-analysis of existing trials would improve inferences regarding the treatment effect.Methods We reviewed randomized trials in Medline, Cochrane and SciSearch, along with other sources of published randomized trials from 1969–2000. Of 215 citations identified, only 3 studies were included.Results The 3 studies (involving 155 patients) were pooled, since they were homogeneous (p > 0.1). Plate fixation gave a lower relative risk of reoperation than intramedullary nailing (RR = 0.26, 95% CI 0.007–0.9, p = 0.03). This translated to a risk reduction of 74% for reoperation when plate fixation was employed. Thus, 1 reoperation could be prevented for every 10 patients treated with plates. Plate fixation also reduced the risk of shoulder problems in comparison to intramedullary nails (RR = 0.10, 95% CI 0.03–0.4, p = 0.00...
