Cutaneous paresthesia after internal plate fixation of clavicle fractures and underlying anatomical observations.

ABSTRACT: To assess the clinical and anatomical causes of cutaneous paresthesia after internal fixation of clavicle fractures.This study included 135 patients who underwent internal fixation of clavicle fractures from May 2013 to June 2016 at the First and Second Affiliated Hospital of Guangxi Medical University. The incidence of postoperative supraclavicular nerve injury, the duration of numbness, and improvements after plate removal were retrospectively analyzed. Seven human cadaver specimens were subsequently dissected to analyze the supraclavicular nerve and its relationship to numbness.Of the 135 patients who underwent internal fixation of clavicle fractures, 26 (19.3%) experienced postoperative cutaneous paresthesia, with 22 (16.3%) and 4 (2.8%) experiencing numbness and pain, respectively. The most intense numbness occurred during the first operative month. Of the 22 patients with numbness, 1 (4.5%), 1 (4.5%), and 20 (90.1%) patients reported mild, moderate, and severe numbness, respectively. Two patients described increased awareness of numbness when in contact with clothes, 2 were psychologically affected by numbness, and 20 (90.1%) reported reduced severity of numbness over time. At the last follow-up, numbness was found to persist in 2 (1.5%) patients. None of the patients was bothered by numbness. Cadaver dissection showed that the supraclavicular nerve emerged from the 1/2 posterior edge of the cervical sternocleidomastoid muscle and subsequently divided into 3 branches, with the lateral branch 2.26?±?1.17?cm from the lateral margin of the acromion, the middle branch near the mid-clavicle, and the medial branch 2.03?±?0.85?cm from the sternal lateral margin.Cutaneous paresthesia is common following internal fixation of the clavicle. Anatomic analysis showed that the nerve could be easily injured during clavicle operation. Numbness improved in most patients, but persisted for up to 2 years and was even permanent in a few. Most patients considered numbness as an insignificant factor in their daily lives.

Project description:IntroductionOpen reduction and internal fixation (ORIF) of displaced midshaft clavicle fractures is associated with higher union rates and earlier functional recovery. However, ORIF with plate fixation is associated with complications including implant irritation and implant failure. Dual plate fixation provides fixation in orthogonal planes, and uses a lower profile fixation technique in comparison to pre-contoured and surgeon-contoured small-fragment locking plates, which may be more prominent. The objective of this study was to conduct a systematic review to summarize outcomes and complications associated with surgical fixation of displaced acute midshaft clavicle fractures with dual plate fixation.MethodsUsing a predetermined study protocol in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines, the databases MEDLINE, EMBASE, and CENTRAL were searched from inception to 2020 to identify studies reporting outcomes in acute midshaft clavicle fractures treated with dual plate fixation. All clinical studies which reported on outcomes of dual plating in patients with acute midshaft clavicle fractures were included. Baseline demographics, plate fixation constructs, fracture union rates, implant removal rates, maintenance of reduction, symptomatic implant rates, wound complications, and functional outcomes were extracted. All extracted data were recorded, and descriptive statistics were summarized. Meta-analysis was performed on fracture union rates and implant removal rates using random-effects modeling using Mantel-Haenszel weighting.ResultsOur literature search identified 2226 unique abstracts, of which eight studies met our study inclusion criteria following review. A total of 278 patients made up of 79.8% male with an average age of 36.0 years were included. The overall dual plate implant removal rate was 4.2% with excellent rates of union reported. Moreover, single plate fixation was associated with a 3.9-fold increased implant removal rate compared to dual plate fixation.ConclusionResults from this systematic review demonstrate that ORIF of displaced midshaft clavicle fractures using a dual plate fixation technique is a viable option to reduce the incidence of implant removal, without negatively impacting the rate of fracture union.Level of evidenceTherapeutic Level III.

Project description:Fractures of the clavicle present very common injuries with a peak of incidence in young active patients. Recently published randomized clinical trials demonstrated an improved functional outcome and a lower rate of nonunions in comparison to non-operative treatment. Anterior chest wall numbness due to injury of the supraclavicular nerve and postoperative pain constitute common surgery related complications in plate fixation of displaced clavicle fractures. We recently developed a technique for mini open plating (MOP) of the clavicle to reduce postoperative numbness and pain. The purpose of this study was to analyze the size of anterior chest wall numbness and the intensity of postoperative pain in MOP in comparison to conventional open plating (COP) of clavicle fractures.24 patients (mean age 38.2 ± 14.2 yrs.) with a displaced fracture of the clavicle (Orthopaedic Trauma Association B1.2-C1.2) surgically treated using a locking compression plate (LCP) were enrolled. 12 patients underwent MOP and another 12 patients COP. Anterior chest wall numbness was measured with a transparency grid on the second postoperative day and at the six months follow-up. Postoperative pain was evaluated using the Visual Analog Scale (VAS).Mean ratio of skin incision length to plate length was 0.61 ± 0.04 in the MOP group and 0.85 ± 0.06 in the COP group (p < 0.05). Mean ratio of the area of anterior chest wall numbness to plate length was postoperative 7.6 ± 5.9 (six months follow-up 4.7 ± 3.9) in the MOP group and 22.1 ± 19.1 (16.9 ± 14.1) in the COP group (p < 0.05). Mean VAS was 2.6 ± 1.4 points in the MOP group and 3.4 ± 1.6 points in the COP group (p = 0.20).In our study, MOP significantly reduced anterior chest wall numbness in comparison to a conventional open approach postoperative as well as at the six months follow-up. Postoperative pain tended to be lower in the MOP group, however this difference was not statistically significant.ClinicalTrials.gov NCT02247778 . Registered 21 September 2014.

Project description:Of all distal radius fractures, 25 % are complete articular fractures (AO/OTA type C fractures). Two thirds of those fractures are displaced and require reduction. According to several International Guidelines, adequately reduced intra-articular distal radius fractures are best treated non-operatively with plaster immobilisation, while surgical fixation is suggested only when the articular step exceeds 2 mm after reduction. However, these recommendations are based on studies that did not differentiate between intra- and extra-articular distal radius fractures. Thus, no clear consensus about the best treatment for patients with displaced intra-articular distal radius fractures can be reached. Despite the lack of evidence, an increase in internal fixation of intra-articular distal radius fractures has been observed over the last decade. The aim of this study is to determine the difference in functional outcome following open reduction and plate fixation compared with non-operative treatment with closed reduction and plaster immobilisation in patients with a displaced intra articular distal radius fracture.This multicentre randomised controlled trial will randomise between open reduction and internal plate fixation (intervention group) and closed reduction and plaster immobilisation (control group). All consecutive adult patients from 18 to 65 years with a displaced intra-articular distal radius fracture (AO/OTA type C), which has been adequately reduced at the Emergency Department according to the Dutch National Guidelines, are eligible for inclusion in this study. The primary outcome is function and pain of the wrist assessed with the Patient-Rated Wrist Evaluation score (PRWE). Secondary outcomes are the Disability of the Arm, Shoulder and Hand score (DASH), pain, quality of life (SF-36), range of motion, grip strength, radiological parameters, complications, crossovers and cost-effectiveness of both treatments. A total of 90 patients will be included in this study.Although displaced intra-articular distal radius fractures are common, there is still no evidence on the optimal treatment for these fractures in patients aged 18 to 65 years. Therefore we aim to determine the difference in functional outcome between open reduction and plate fixation and closed reduction and plaster immobilisation.This study is registered at ClinicalTrials.gov ( NCT02651779 ) on January 4(th) 2016.
