Complications after non-surgical management of proximal humeral fractures: a systematic review of terms and definitions.

ABSTRACT:

Background

A majority of proximal humeral fractures can be managed without surgery. Recent randomized clinical trials and meta-analyses even question the benefit of surgical treatment for displaced 3-, and 4-part fractures. However, evidence-based treatment recommendations, balancing benefits and harms, presuppose a common reporting of complications and adverse events, which at the moment is largely missing. Therefore we systematically reviewed the use of terms and definitions of complications after nonsurgical management of proximal humeral fractures.

Methods

We searched PubMed, EMBASE, Cochrane Library, Scopus and WorldCat (2010-2017) and included articles and book chapters containing complication terms or definitions. Two reviewers independently extracted and grouped terms and definitions according to a predefined scheme. Terms and definitions concerning non-surgical management were tabulated, grouped and analyzed qualitatively.

Results

The initial search identified 1376 references from which 470 articles were selected for full-text retrieval. Data-extraction included first articles published in 2017, was then performed iteratively in batches of 20 articles, and terminated after retrieval of 91 articles when no additional definitions or terms was found. In addition, 12 book chapters were reviewed from an initial list of 100. No general definition of a complication was found. A total of 69 terms for complications after non-surgical management were identified from 19 articles. Sixty-seven terms regarded local events. The most commonly reported event terms regarded osteonecrosis, malunion, secondary displacement and rotator cuff problems. Seven individual terms were accompanied by some kind of definition. Most terms and definitions were based on radiographical assessments.

Conclusions

We found no consensus in the use of terms and definitions of complications after nonsurgical management of proximal humeral fractures. Multiple terms, some synonymous, some partly synonymous, some distinct, were used. Few complication terms were explicitly defined. Development and validation of an internationally consensus-based core event set for complications after proximal humeral fractures managed non-surgically is needed.

Project description:BACKGROUND:The most frequently used surgical procedures for treating a proximal humeral fracture (PHF) are plate osteosynthesis, nail osteosynthesis and arthroplasty. Evidence-based recommendations for an appropriate surgical procedure after PHF requires transparent and valid safety data. We performed a systematic review to examine reported terms and definitions of complications after surgically-treated PHFs. METHODS:A literature search was conducted on PubMed, Cochrane Library, EMBASE, Scopus and WorldCat to identify clinical articles and book chapters on complications of PHF published from 2010 to 2017. Complication terms and definitions were extracted from each selected article independently by two reviewers and grouped according to a predefined scheme. RESULTS:From 1376 initial references, we selected 470 articles, of which 103 were reviewed in reverse chronological order until no further information was gained. Twelve book chapters were reviewed. We found 667 local event terms associated with complications after surgical treatment of PHFs. The most frequently used event terms were infection (52 references), nonunion (n?=?42), malunion (n?=?35), avascular necrosis (n?=?27) and pain (n?=?25). Overall, 345, 177, 257 and 102 local event terms were related to plating, nailing, arthroplasty and other surgical techniques, respectively. Radiological assessment was the basis for the majority of event terms and complication definitions. Thirty-six event definitions were extracted, mostly defining the terms "secondary fracture displacement", "screw perforation/cutout", "malunion", "delayed healing" and "notching". CONCLUSION:Scientific literature on surgically-managed PHF uses different terms to describe complications and without approved definitions, which highlights a lack of agreement on adverse event terminology for PHFs. Defined event terms are mostly based on radiological observations. Consensus among shoulder surgeons on a core event set is indispensable to support the standardization of safety reporting for surgically-treated PHFs.

Project description:BackgroundHumeral head inferior subluxation often occurs immediately after osteosynthesis for proximal humeral fracture; however, the underlying cause remains largely unknown. In addition, the prognosis of postoperative inferior subluxation has not been fully investigated. This study aimed to clarify the predictive factors that affected the onset of postoperative inferior subluxation using multivariate analysis and examine the postoperative course of inferior subluxation and its influence on postoperative outcomes.MethodsWe retrospectively reviewed 212 patients who underwent osteosynthesis for Neer 2- or 3-part proximal humeral fractures. In the multivariate analysis, the dependent variable was set as the inferior subluxation observed 1 week after the surgery. The explanatory variables included age, sex, affected side, body mass index, smoking, local osteoporosis, preoperative axillary nerve injury, time from injury to surgery, fracture dislocation, fracture pattern, preoperative inferior subluxation, surgical procedure, surgical approaches, blood loss, operative time, and postoperative drainage. Baseline variables, which were observed to be significant in the univariate analysis, were included in multivariate models. Furthermore, based on the presence of inferior subluxation at 1 week after the surgery, we divided the patients into two groups: with inferior subluxation (+IS group) and without inferior subluxation (-IS group). We compared the postoperative outcomes (incidence of postoperative complications and range of motion) between these two groups.ResultsOf 212 patients, 64 (30.7%) experienced inferior subluxation at 1 week after the surgery. On multivariate analyses, preoperative inferior subluxation (odds ratio = 4.69; 95% confidence interval = 2.45-9.76; P < .001) and longer operative time (odds ratio = 1.01; 95% confidence interval = 1.00-1.02; P = .049) were the risk factors for postoperative inferior subluxation. In the +IS group, inferior subluxation resolved at 1 year after the surgery in 89.5% of patients. There was no significant difference in the postoperative outcome between the +IS and -IS groups. However, four of six patients with persistent inferior subluxation, more than 6 months after the surgery, experienced complications, such as varus angulation of the humeral head or screw joint perforation.ConclusionsThis study provides new information on the risk factors for and prognosis of postosteosynthesis inferior subluxation in patients with proximal humeral fracture. Longer operative time and presence of preoperative inferior subluxation was associated with an increased risk of postoperative inferior subluxation, although it was temporary in most cases, and had no significant influence on the postoperative outcomes. However, in patients with persistent inferior subluxation of more than 6 months duration, inferior subluxation may be related to postoperative complications.

Project description:BackgroundWith the aging of the world's population, the social and economic implications of osteoporotic fractures are at epidemic proportions. This study was performed to test the hypothesis that a proximal humeral fracture is an independent risk factor for a subsequent hip fracture and that the risk of the subsequent hip fracture is highest within the first five years after the humeral fracture.MethodsA cohort of 8049 older white women with no history of a hip or humeral fracture who were enrolled in the Study of Osteoporotic Fractures was followed for a mean of 9.8 years. The risk of hip fracture after an incident humeral fracture was estimated with use of age-adjusted Cox proportional hazards regression analysis with time-varying variables; women without a humeral fracture were the reference group. Cox regression analysis was used to evaluate the timing between the proximal humeral and subsequent hip fracture. Risk factors were determined on the basis of a review of the current literature, and we chose the variables that were most predictive and easily ascertained in a clinical setting.ResultsThree hundred and twenty-one women sustained a proximal humeral fracture, and forty-four of them sustained a subsequent hip fracture. After adjustment for age and bone mineral density, the hazard ratio for hip fracture for subjects with a proximal humeral fracture relative to those without a proximal humeral fracture was 1.83 (95% confidence interval = 1.32 to 2.53). After multivariate adjustment, this risk appeared attenuated but was still significant (hazard ratio = 1.57; 95% confidence interval = 1.12 to 2.19). The risk of a subsequent hip fracture after a proximal humeral fracture was highest within one year after the proximal humeral fracture, with a hazard ratio of 5.68 (95% confidence interval = 3.70 to 8.73). This association between humeral and hip fracture was not significant after the first year, with hazard ratios of 0.87 (95% confidence interval = 0.48 to 1.59) between one and five years after the humeral fracture and 0.58 (95% confidence interval = 0.22 to 1.56) after five years.ConclusionsIn this cohort of older white women, a proximal humeral fracture independently increased the risk of a subsequent hip fracture more than five times in the first year after the humeral fracture but was not associated with a significant increase in the hip fracture risk in subsequent years.
