BackgroundThe number of displaced midshaft clavicle fractures treated surgically is increasing and plate fixation is often the treatment modality of choice. The study quality and scientific levels of evidence at which possible complications of this treatment are presented vary greatly in literature.PurposesThe purpose of this systematic review is to assess the prevalence of complications concerning plate fixation of dislocated midshaft clavicle fractures.MethodsA computer-based search was carried out using EMBASE and PUBMED/MEDLINE. Studies included for review reported complications after plate fixation alone or in comparison to either treatment with intramedullary pin fixation and/or nonoperative treatment. Two quality assessment tools were used to assess the methodological quality of the studies. Included studies were ranked according to their levels of evidence.ResultsAfter study selection and reading of the full texts, 11 studies were eligible for final quality assessment. Nonunion and malunion rates were less than 10% in all analysed studies but one. The vast majority of complications seem to be implant related, with irritation or failure of the plate being consistently reported on in almost every study, on average ranging from 9 to 64%.ConclusionThe quantity of relevant high evidence studies is low. With low nonunion and malunion rates, plate fixation can be a safe treatment option for acute dislocated midshaft clavicle fractures, but complications related to the implant material requiring a second operation are frequent. Future prospective trials are needed to analyse the influence of various plate types and plate position on implant-related complications.
More than 20% of the patients with severe injuries were not transported to a level I trauma center. These patients are at risk for preventable morbidity and mortality. This finding indicates the need for improvement of the prehospital triage protocol.
Purpose The goal of this study was to assess if unprotected weight-bearing as tolerated is superior to protected weightbearing and unprotected non-weight-bearing in terms of functional outcome and complications after surgical fixation of Lauge-Hansen supination external rotation stage 2-4 ankle fractures. Methods A multicentered randomized controlled trial was conducted in patients ranging from 18 to 65 years of age without severe comorbidities. Patients were randomized to unprotected non-weight-bearing, protected weight-bearing, and unprotected weight-bearing as tolerated. The primary endpoint of the study was the Olerud Molander Ankle Score (OMAS) 12 weeks after randomization. The secondary endpoints were health-related quality of life using the SF-36v2, time to return to work, time to return to sports, and the number of complications. Results The trial was terminated early as advised by the Data and Safety Monitoring Board after interim analysis. A total of 115 patients were randomized. The O'Brien-Fleming threshold for statistical significance for this interim analysis was 0.008 at 12 weeks. The OMAS was higher in the unprotected weight-bearing group after 6 weeks c(61.2 ± 19.0) compared to the protected weight-bearing (51.8 ± 20.4) and unprotected non-weight-bearing groups (45.8 ± 22.4) (p = 0.011). All other follow-up time points did not show significant differences between the groups. Unprotected weight-bearing showed a significant earlier return to work (p = 0.028) and earlier return to sports (p = 0.005). There were no differences in the quality of life scores or number of complications. Conclusions Unprotected weight-bearing and mobilization as tolerated as postoperative care regimen improved short-term functional outcomes and led to earlier return to work and sports, yet did not result in an increase of complications.
This study validates the sensitivity of near-infrared spectroscopy and provides estimates for the sensitivity and specificity of magnetic resonance imaging in chronic exertional compartment syndrome in a large group of patients. The sensitivity of noninvasive near-infrared spectroscopy is clinically equivalent to that of invasive intracompartmental pressure measurements.
The clavicle hook plate is a suitable implant for Neer type II clavicle fractures. The advantage of this osteosynthesis is the possibility of immediate functional aftercare. We observed a high percentage of discomfort due to the implant; therefore, we advise to remove the implant as soon as consolidation has taken place.
The patients in the plate-fixation group recovered faster than the patients in the intramedullary nailing group, but the groups had similar results at six months postoperatively and the time of final follow-up. The rate of complications requiring revision surgery was low. Implant-related complications occurred frequently and could often be treated by implant removal.
Background Studies comparing plate with intramedullary nail fixation of displaced midshaft clavicle fractures show faster recovery in the plate group and implant-related complications in both groups after short-term followup (6 or 12 months). Knowledge of disability, complications, and removal rates beyond the first postoperative year will help surgeons in making a decision regarding optimal implant choice. However, comparative studies with followup beyond the first year or two are scarce. Questions/purposes We asked: (1) Does plate fixation or intramedullary nail fixation for displaced midshaft clavicle fractures result in less disability? (2) Which type of fixation, plate or intramedullary, is more frequently associated with implant-related irritation and implant removal? (3) Is plate or intramedullary fixation associated with postoperative complications beyond the first postoperative year?Methods Between January 2011 and August 2012, patients with displaced midshaft clavicle fractures were enrolled and randomized to plate or intramedullary nail fixation. A total of 58 patients with plate and 62 patients with intramedullary nails initially were enrolled. Minimum followup was 30 months (mean, 39 months; range, 30-51 months). Two patients (3%) with plate fixation and two patients (3%) with intramedullary nails were lost to followup. The QuickDASH was obtained at final followup and compared between patients who had plate fixation and those who had intramedullary nail fixation. Postoperative complications measured include infection, implant-related irritation, implant failure, nonunion, and refracture after implant removal. Indications for implant removal included implant-related irritation, implant failure, nonunion, patient's wish, or surgeon's preference. Results Between patients with plate versus intramedullary nail fixation, there were no differences in QuickDASH The institution of one or more of the authors (FJW, RMH, EJV) has received, during the study period, funding from the AO Foundation ((Dübendorf, Switzerland).

Each author certifies that his institution approved the human protocol for this investigation, that all investigations were conducted in conformity with ethical principles of research, and that informed consent for participation in the study was obtained. Conclusions After a mean followup of 39 months, disability scores were excellent. Major complications did not occur after the 1-year followup. A frequent and bothersome problem after both surgical treatments is implant-related irritation, resulting in high rates of implant removal, after 1 year. Future research could focus on analyzing risk factors for implant irritation or removal. Level of Evidence Level II, therapeutic study.
