Outcome of distal tibia physeal fractures: a review of cases as related to risk factors

IntroductionThe physeal fractures represent the 20–30% of all fractures of the child. The distal tibial physis is the third most frequently injured. The most important complication is the premature physeal closure (PPC). Aim of this study is to evaluate risk factors that can influence the outcome like fracture pattern, fracture displacement, mechanism of injury and treatment method. Material and MethodsThe records of 46 patients treated for distal tibia physeal fractures between 2003 and 2013 were reviewed. Initial injury radiographs were categorized according to Salter-Harris and Dias-Tachdjian classifications and the initial and post-treatment fracture displacementwas measured. Any complex fractures had preoperative CT for additional assessment. Three different types of treatment were compared: closed reduction and casting versus closed reduction and percutaneous pinning versus ORIF. ResultsTherewas significantly less residual displacement in patients who had ORIF versus those who had closed reduction and percutaneous Kirschner wires or plaster only. In fractures with an intact fibula, we found significantly less initial and residual displacement. The Dias-Tachdjian classification is significantly correlated with the displacement. Patients studied with CT show a less degree of post reduction displacement. At the final follow-up we found only one PPC as complication. ConclusionThe physeal fractures are very common in children and the main goal is to avoid any complications. It is clear that the development of complications after distal tibial fractures is due to multiple contributing factors like skeletal maturity, severity of injury, fracture type, degree of comminution and displacement aswell as adequacy of reduction. A premature physeal closure is the most common complication. The fibula fracture can play an important role in initial displacement. The presence of an intact fibula and a good anatomical reduction have a significant positive influence on fracture outcome.

Obstacles to reduction in infantile developmental dysplasia of the hip.

PurposeIdentification of anatomical structures that block ­reduction in developmental dysplasia of the hip (DDH) is ­important for the management of this challenging condition. Obstacles to reduction seen on arthrogram are well-known. However, despite the increasing use of MRI in the assessment of adequacy of reduction in DDH, the interpretation of MRI patho-anatomy is ill-defined with a lack of relevant literature to guide clinicians.MethodThis is a retrospective analysis of the MRI of patients with DDH treated by closed reduction over a five-year period (between 2009 and 2014). Neuromuscular and genetic disorders were excluded. Each MRI was analysed by two orthopaedic surgeons and a paediatric musculoskeletal radiologist to identify the ligamentum teres, pulvinar, transverse acetabular ligament (TAL), capsule, labrum and acetabular roof cartilage hypertrophy. Inter- and intraobserver reliability was calculated. The minimum follow-up was 12 months.ResultsA total of 29 patients (38 hips) underwent closed reduction for treatment of DDH. Eight hips showed persistent subluxation on post-operative MRI. Only three of these eight hips showed an abnormality on arthrogram. The pulvinar was frequently interpreted as ‘abnormal’ on MRI. The main obstacles identified on MRI were the ligamentum teres (15.8%), labrum (13.1%) and acetabular roof cartilage hypertrophy (13.2%). The inter-rater reliability was good for TAL, capsule and pulvinar; moderate for ligamentum teres and labrum; and poor for hypertrophied cartilage.ConclusionThe labrum, ligamentum teres and acetabular roof cartilage hypertrophy are the most important structures seen on MRI preventing complete reduction of DDH. Focused interpretation of these structures may assist in the management of DDH.

Audit changes practice; simple education intervention can lead to better outcome for ankle fractures undergoing surgery

Category: Ankle, Trauma Introduction/Purpose: Unstable ankle fractures are common orthopaedic injuries and majority requires open reduction and internal fixation (ORIF). The goal of surgery is to achieve anatomical reduction and stable fixation of fracture. Recent literature reports malreduction rate as high as 25% to 33%. There is emerging evidence that malreduction leads to poor patient reported outcome (PROMs) and may render additional surgery. The aim of this study was to evaluate the quality of anatomical reduction and surgical fixation of ankle fractures and the effect of a simple education intervention on the adequacy of reduction of these fractures. Methods: An audit cycle was completed starting with retrospective review (phase 1) of 114 consecutive cases of ankle fracture that underwent ORIF between October 2006 and December 2007. Data was retrieved from theatre log and PACS. Age, fracture morphology, time to surgery, time to revision surgery and the quality of anatomical reduction were assessed by three surgeons using three radiological parameters (Pettrone’s criteria + Weber’s dime test). Paediatrics, pathological fractures, open fractures were excluded. The results were conveyed and interventions in the form of regional teaching and introduction of radiological criteria were implemented. Phase 2 (re-audit) was conducted with prospective review of 72 cases between December 2015 and June 2016. Inter-rater reliability was determined using kappa value. Chi- square test was used to compare malreduction rates between 2 phases. Logistic regression was performed for age, gender, time to ORIF with regards to revision surgery. P value < 0.05 was considered significant Results: Results of initial cohort showed significant rate of malreduced fixation in 25% of cases (29 out of 114). After implementation of interventions, malreduction rate reduced to 12.6% (9 out of 72). Of these nine malreduced cases, 3 cases underwent early revision surgery within the first 6 weeks of surgery. There was no significant correlation between age, gender and time to surgery, and time to revision surgery within 3 months of surgical fixation (p = 0.4). Using three radiological parameters (Weber’s dime test, tibiofibular overlap and medial clear space) the mean kappa values for inter-rater reliability was 0.786 (0.727- 0.861), representing a substantial agreement using three radiological parameters in order to avoid failure and or further surgery. Conclusion: This study demonstrates that simple education intervention locally can lead to better understanding of fixation and reduce the rate of malreduction of these fractures. We suggest using three radiological parameters in correction of corresponding anatomy of ankle mortise is a reliable tool to avoid malreduction. Malreductions were more likely to occur in complex fractures with syndesmotic injuries.

The Validity and Reliability of a Pocket-Sized Ultrasound to Diagnose Distal Radius Fracture and Assess Quality of Closed Reduction

Handheld ultrasound technology is increasingly used in health care. Its use for fracture care has not been adequately evaluated. The purpose of this study was to evaluate handheld, pocket-sized ultrasound in the diagnosis and assessment of reductions in distal radius fractures. A total of 23 patients with distal radius fractures (average age, 53 years; 13 women) and 20 control patients (average age, 53 years; 10 women) were prospectively enrolled. All patients with distal radius fractures underwent standard, 3-view radiographic and ultrasonographic examinations of the wrist before and after closed reduction. Control patients had a one-time standard radiographic and ultrasonographic examination of the wrist. Radiographs were used as the reference standard. All images were assessed for the presence or absence of a fracture by a board-certified, hand fellowship-trained orthopedic surgeon and musculoskeletal fellowship-trained radiologist who were blinded to the study protocol. If a fracture was detected, the adequacy of reduction was assessed. The sensitivity of distal radius fracture diagnosis on ultrasound was 100% and specificity ranged from 90% to 95%. The sensitivity of identifying a satisfactory reduction ranged from 76% to 93% and specificity was 93% to 94%. Interrater reliability between the musculoskeletal radiologist and hand surgeon was κ= 0.86 for diagnosing the fracture and κ= 0.82 for identifying a satisfactory reduction. Intrarater reliability ranged from κ= 0.82 to 0.86. A pocket-sized, handheld diagnostic ultrasound device demonstrates the ability to diagnose distal radius fractures and assess fracture reductions.

Teaching the Basics: Development and Validation of a Distal Radius Reduction and Casting Model.

Approximately one-third of reduced pediatric distal radius fractures redisplace, resulting in further treatment. Two major modifiable risk factors for loss of reduction are reduction adequacy and cast quality. Closed reduction and immobilization of distal radius fractures is an Accreditation Council for Graduate Medical Education residency milestone. Teaching and assessing competency could be improved with a life-like simulation training tool. Our goal was to develop and validate a realistic distal radius fracture reduction and casting simulator as determined by (1) a questionnaire regarding the "realism" of the model and (2) the quantitative assessments of reduction time, residual angulation, and displacement. A distal radius fracture model was created with radiopaque bony segments and articulating elbows and shoulders. Simulated periosteum and internal deforming forces required proper reduction and casting techniques to achieve and maintain reduction. The forces required were estimated through an iterative process through feedback from experienced clinicians. Embedded monofilaments allowed for quantitative assessment of residual displacement and angulation through the use of fluoroscopy. Subjects were asked to perform closed reduction and apply a long arm fiberglass cast. Primary performance variables assessed included reduction time, residual angulation, and displacement. Secondary performance variables consisted of number of fluoroscopic images, casting time, and cast index (defined as the ratio of the internal width of the forearm cast in the sagittal plane to the internal width in the coronal plane at the fracture site). Subject grading was performed by two blinded reviewers. Interrater reliability was nearly perfect across all measurements (intraclass correlation coefficient range, 0.94-0.99), thus disagreements in measurements were handled by averaging the assessed values. After completion the participants answered a Likert-based questionnaire regarding the realism of simulation. Eighteen participants consented to participate in the study (eight attending pediatric orthopaedic surgeons, six junior residents, four senior residents). The performances of junior residents (Postgraduate Year [PGY] 1-2), senior residents (PGY 3-5), and attending surgeons were compared using one-way ANOVA with Tukey's-adjusted pairwise comparisons. The majority of participants (15 of 18) felt that the model looked, felt, and moved like a human forearm. All participants strongly agreed that the model taught the basic steps of fracture reduction and should be implemented in orthopaedic training. Attending surgeons reduced fractures in less time than junior residents (60 ± 27 seconds versus 460 ± 62 seconds; mean difference, 400 seconds; 95% CI, 335-465 seconds; p < 0.001). Residual angulation was greater for junior residents when compared with attending surgeons on AP (7° ± 5° versus 0.7° ± 0.9°; mean difference, 6.3°; 95% CI, 3°-11°; p = 0.003) and lateral (27° ± 7° versus 7° ± 5°; mean difference, 20°; 95% CI, 13°-27°; p = 0.001) radiographs. Similarly, residual displacement was greater for junior residents than either senior residents (mean difference, 16 mm; 95% CI, 2-34 mm; p = 0.05) or attending surgeons (mean difference, 15 mm; 95% CI, 3-27 mm; p = 0.02) on lateral images. There were no differences identified in secondary performance variables (number of fluoroscopic images, casting time, and cast index) between groups. This is the first distal radius fracture reduction model to incorporate an elbow and shoulder and allow quantitative assessment of the fracture reduction. This simulator may be useful in an orthopaedic resident training program to help them reach a defined minimum level of competency. This simulator also could easily be integrated in other accreditation and training programs, including emergency medicine. Level II, therapeutic study.

A COMPARATIVE STUDY OF CORTICAL LAG SCREWS AND MINIPLATES FOR INTERNAL FIXATION OF MANDIBULAR SYMPHYSEAL REGION FRACTURES

INTRODUCTION: The management of facial trauma is one of the most rewarding and demanding aspects of oral and maxillofacial surgery. Being the most prominent mobile bone of the facial skeleton, mandible fracture occurs more frequently than any other fracture. OBJECTIVES: The aim of this study was to compare the outcomes of treatment by the use of cortical lag screws versus miniplates, in patients who have a fracture in the mandibular symphyseal region. MATERIALS AND METHODS: The present study was conducted on fourteen patients with age ranged from 19-48 years. The patients had mandibular symphyseal region fractures requiring open reduction and internal fixation. The patients were clinically examined postoperatively by assessment of pain, edema, surgical wound, occlusion, teeth vitality and nerve injury. They also were assessed radiographically using orthopantomogram and cone beam computerized tomography (CBCT) to evaluate the adequacy of reduction, healing progression and bone density of the fractured segments. CONCLUSIONS: Cortical screw fixation using the lag screw principle offers the advantages of fixation, using minimal hardware, and achieving inter-fragmentary compression, and associated with minimal pain and edema when considering the treatment of linear symphyseal region fractures.

Surgical management of unstable supracondylar fractures of humerus in children by closed reduction and percutaneous k wire fixation by crossed versus triple pin configuration: A comparative study

Background: Supracondylar fracture of humerus in children is one of the most common fractures seen in pediatric orthopedic clinic setting worldwide. Closed reduction and percutaneous K wire fixation is preferred method of treatment and should be attempted at earliest possible time. In this study, displaced extension type supracondylar fractures in children were managed with closed reduction and percutaneous K wire fixation using image intensifier so as to study age, sex incidence and side preponderance, assess clinical and radiological outcomes. To compare clinical outcomes in two types of pin configurations (crossed and triple) and early and late complications associated with these procedures. Materials and methods: This study was conducted between June 2013 and June 2015 in the Department of Orthopaedics in Karnataka Institute of Medical Sciences, Hubballi. The mean age of the patients was 8.73 years (range 6–13 years). The male/female ratio was 3:1 and left side was involved in 53.8 % whereas 42.2% had right sided injuries. All the 26 admitted patients had extension type injury with 96.15% fractures being Gartland type III and 3.85 % were type II. Posteromedial displacement was noted in 57.7 % whereas 42.3 % fractures were posterolaterally displaced. In 13 cases, crossed K wires were used whereas, in 13 cases, two lateral and one medial K wire was used. K wires were removed at 4 weeks postoperatively and follow-up was done at 8, 12 weeks and final follow-up at 6 months when they were evaluated according to the criteria described by Flynn. Chi square test and Fischer –Exact test was used as a statistical tools to compare results among different variables. Results: All 26 patients had satisfactory outcomes (100%) as per Flynn’s criteria. Although Triple pinning has shown better results but there was no statistical difference in the final outcomes and complication rates in patients treated by either crossed or triple pinning technique due to small sample size. Younger age patients were found to have better final clinical outcomes to older children. Patients who had Baumann angle within 4 degrees compared to normal side had better final outcomes and it can used as a reliable radiologic parameter to assess adequacy of reduction. Conclusion: Closed reduction and percutaneous fixation using K wires gives excellent results and is the most accepted modality for treating displaced supracondylar fractures of humerus in children. Triple pinning has shown encouraging results in comparison to Crossed pinning, but larger sample size is needed to give statistical significance to the comparative study.

Surgical Results of the Cephalomedullary Nail for the Femoral Intertrochanteric Fracture: Comparison between Non-experienced Surgeons and Experienced Surgeon.

PurposeCephalomedullary nail (CM nail) in the treatment of femoral intertrochanteric fractures is in the lime light in recent years. The purpose of this study is to compare surgical outcomes between experienced surgeon and non-experienced surgeons in respect of CM nail for femoral intertrochanteric fractures.Materials and MethodsThe 129 patients underwent CM nail for femoral intertrochanteric fracture more than six months of follow-up from April 2011 to March 2014 in Seoul Medical Center (Seoul, Korea) were participated in this study. For this study, group A consisted of experienced surgeons who performed more than 500 times of CM nail, and group B consisted of non-experienced surgeons who performed less than 50 times of CM nail. Clinical and radiologic outcomes, complications and the need for reoperation between both groups were compared in the study.ResultsAccording to clinical result, both the mean operation time and transfusion volume were significantly longer and greater in group B (P<0.05). In the radiologic outcomes, adequacy of reduction, tip-apex distance and numbers of case placed in the Cleveland zones 5, 6 and 8; there was no statistical difference between both groups. Moreover, rate of complication and reoperation had same results as radiologic outcomes.ConclusionThere was no significant difference with statistical data in complications from CM nail for femoral intertrochanteric fractures between experienced surgeon and non-experienced surgeon. Although the operation time and transfusion volume were significantly longer and greater in the case of operation by non-experienced surgeon, satisfactory performance was seen in the complications and the need for reoperation.

Management of Zygomatic Fractures in Young Patients: Technical Modifications for Aesthetic and Functional Results.

The zygomaticomaxillary complex is very vulnerable to injury because of its intrinsically prominent convexity. There are 2 different surgical approaches for the therapy of these fractures: closed reduction and open reduction. In the open reduction 2 or 3 fixation points with related incisions are usually necessary in dislocated fractures: osteosynthesis must be performed starting from zygomaticofrontal suture when dislocated at this site, followed by zygomatic body fixation on the anterior sinus wall, anterior orbital floor margin fixation, and finally orbital floor reconstruction in case of eye globe dislocation with diplopia. This study evaluated the combination of the transconjunctival (TC) approach without canthotomy in association with the transoral maxillary approach and lateral rim skin incision (SI) without canthotomy for frontozygomatic dislocated fractures to achieve proper reduction and stabilization without any aesthetic decay in young patients. A less invasive and more aesthetic technique is shown for treating dislocated zygomaticomaxillary complex fractures with 2 or 3 fixation points and platelet-rich fibrin (PRF) use to promote tissue healing. Ten patients (mean age: 32) were referred for dislocated zygomaticomaxillary complex fracture. Five patients were treated by TC approach without canthotomy in association with the transoral maxillary approach and, when needed, eyebrow SI without canthotomy for frontozygomatic dislocated fractures (group 1). Five more patients were treated by traditional subciliar incision at lower eyelid and vertical lateral incision at lateral margin of the orbit (group 2). Autologous PRF for orbital floor reconstruction was used. The follow-up period was 6 months long. Follow-up radiographs (TC) and photos were routinely used to evaluate the adequacy of reduction and lower eyelid right position or retraction. All cases were successful; there were no problems at surgery and postoperative time. During the 6-month follow-up, all 5 patients of group 1 showed satisfactory facial symmetry, no noticeable scarring, no ectropion or lower eyelid significant droop, and no functional impairment. Mean difference for lower eyelid droop between the 2 groups of patients was 1.4 mm at T1 and 1.2 mm at T2. Aesthetic result is a priority in the treatment planning of orbitozygomatic fractures because of the fundamental role of the eye and lid area in the aesthetic of the face. In our experience best aesthetic results were achieved through a latero cantal horizontal SI combined to a vertical periosteal incision at the frontozygomatic rim without canthotomy, thus performing a different double-layer incision. In the patients with large orbital floor dislocation, reconstructive titanium mesh was covered by autologous PRF membranes, which can improve the vascularization of the surgical site, by promoting neoangiogenesis. In young patients these techniques are indicated because of the need of better aesthetic results that can be achieved by preventing postoperative functional impairment with lower eyelid droop and unnatural aesthetic asymmetry of the 2 lower lids. This more conservative technique resulted in better aesthetic results, avoiding most common complications.

What is the Single Most Important Technical Aspect When Fixing a Proximal Humeral Fracture with A PHILOS Plate?”

Introduction: This study aimed to identify technical factors contributing to hardware complications with PHILOS plates. Methods: A five year retrospective radiological review of all PHILOS platings at our institution was performed. Pathological fractures and revision cases were excluded. (79 patients, 73 females, mean age 88 and range 15-108). AP (Antero-posterior) radiographs were used to assess infero-medial support (presence or absence of calcar screws), adequacy of reduction by measuring the neck-shaft angle, and loss of reduction. The first postoperative radiograph was compared with a follow up radiograph from more than 12 months after the index surgery and cases that required revision were identified. Six patients underwent further surgery for either screw perforation into the joint or plate failure. Cases were then divided into two groups, a revision group (R) and an unrevised group (U), and statistical analysis using Wilcoxon’s rank test for non-parametric data was performed looking at the differences between mean neck shaft angle, adequacy of reduction and loss of reduction in both groups. Results: A clinically and statistically significant difference was found in the mean neck shaft angle between the unrevised and the revised groups. The mean neck shaft angle was 129° in patients who did NOT undergo any further procedures (N = 73). The mean neck shaft angle was 110° in patients who DID undergo revision (N = 10) P <0.03. Conclusion: Restoration of an adequate neck-shaft angle was the most important determinant of successful PHILOS plate fixation. If this was not achieved, screw perforation or plate failure occurred.

Conventional 2.0 mm Miniplates versus 3D Miniplate in Mandibular Fracture Fixation

The aim of the present study was to clinically and radiographically compare and evaluate the treatment outcomes using 3D miniplate versus conventional 2.0 mm miniplates in fractures fixation of the anterior mandible. The study enrolled 16 patients with a total of 18 fractures; suffering from anterior mandibular fractures (symphysis and/or parasymphysis) requiring open reduction and internal fixations through an intra-oral approach. Groups I patients were fixed using 3D titanium miniplates and screws. Group II patients were fixed using two 2.0 mm titanium miniplates and screws.Postoperative primary clinical treatment outcome points for comparative evaluation for all patients were fracture stability, the need for additional IMF, the need for minor occlusal adjustments and satisfactory occlusion. Secondary assessment points were infection, wound dehiscence and neurosensory deficit. Radiographic evaluation postoperatively was in terms of reduction adequacy, bone union and condylar positional change measurement. With respect to all the evaluated parameters, statistical analysis showed no statistically significant difference between the two groups in termsof clinical and radiographic treatment outcomes.

Cannulated cancellous screws fixation in intracapsular fracture neck femur: a study with an emphasis on result of osteosynthesis

&lt;p class="abstract"&gt;&lt;strong&gt;Background:&lt;/strong&gt; Fracture neck of femur has always presented a great challenge to the orthopaedic surgeons. It is rightly called as “unsolved fracture” as far as treatment and results are concerned. Results generally depend upon time period elapsed from fracture to surgery, adequacy of reduction and fixation. Fixation with cannulated cancellous screw is usually adequate for femoral neck fractures. The aim of the study was to analyse the results of treatment of fracture neck of femur with cannulated cancellous screw fixation and to compare the results with others in the literature using the same modality. &lt;/p&gt;&lt;p class="abstract"&gt;&lt;strong&gt;Methods:&lt;/strong&gt; 25 patients with intra capsular neck of femur fracture were followed for a period of two years post-surgery and their functional outcome was assessed based upon harris hip scoring system.&lt;strong&gt;&lt;/strong&gt;&lt;/p&gt;&lt;p class="abstract"&gt;&lt;strong&gt;Results:&lt;/strong&gt; According to harris hip scoring system, we had excellent results in 72% cases, good in 16% cases, fair in 8% and poor in 4%. One patient went into non-union and two developed avascular necrosis of femoral head.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions:&lt;/strong&gt; Management of intracapsular fracture neck of femur with cannulated cancellous screw fixation is a very good method of treatment being a surgically easy procedure. Use of multiple cannulated cancellous screw have a compression effect at the fracture site. It also avoids re displacement and rotation.&lt;/p&gt;

Radiographic and CT Assessment of Reduction of Calcaneus Fractures Using a Limited Sinus Tarsi Incision.

The lateral extensile incision for fixation of displaced intra-articular calcaneus fractures allows for fracture reduction but has been associated with high rates of soft tissue complications. This has prompted a search for less invasive methods of fracture fixation. The purpose of the present study was to determine the adequacy of reduction and rate of complications associated with operative fixation of calcaneal fractures using a limited sinus tarsi approach. A limited sinus tarsi incision with plate fixation was utilized for treatment of 39 displaced intra-articular calcaneal fractures in 35 consecutive patients as part of a single surgeon series. Imaging assessment of previously described fracture displacement measures was undertaken in preoperative and postoperative radiographs and CT. A retrospective chart review was conducted to identify postoperative complications. Mean preoperative Bohler angle measurement was 7.7 (range, -26.0 to 30.0) degrees and the mean final postoperative standing Bohler angle was 25.5 (range, 12.3 to 37.7) degrees. Postoperative CT demonstrated that subtalar articular reduction was within 2 mm of anatomic in 91% of patients. There were 2 instances of superficial wound dehiscence (5.1%) and 1 deep infection (2.6%) that required debridement and complete hardware removal. Visual analog score (VAS) for pain averaged 3 of 10 in the 32 available patients at 1-year follow-up. Eight of these patients (25%) reported no pain (0/10) at final follow-up. Operative fixation of displaced intra-articular calcaneal fractures utilizing the limited sinus tarsi approach resulted in acceptable fracture reduction and a low rate of complications. Level IV, retrospective case series.

Ultrasound-Assisted Distal Radius Fracture Reduction

IntroductionClosed reduction of distal radius fractures (CRDRF) is a commonly performed emergency department (ED) procedure. The use of point-of-care ultrasound (PoCUS) to diagnose fractures and guide reduction has previously been described. The primary objective of this study was to determine if the addition of PoCUS to CRDRF changed the perception of successful initial reduction. This was measured by the rate of further reduction attempts based on PoCUS following the initial clinical determination of achievement of best possible reduction.Methods We performed a multicenter prospective cohort study, using a convenience sample of adult ED patients presenting with a distal radius fracture to five Canadian EDs. All study physicians underwent standardized PoCUS training for fractures. Standard clinically-guided best possible fracture reduction was initially performed. PoCUS was then used to assess the reduction adequacy. Repeat reduction was performed if deemed indicated. A post-reduction radiograph was then performed. Clinician impression of reduction adequacy was scored on a 5 point Likert scale following the initial clinically-guided reduction and following each PoCUS scan and the post-reduction radiograph.Results There were 131 patients with 132 distal radius fractures. Twelve cases were excluded prior to analysis. There was no significant difference in the assessment of the initial reduction status by PoCUS as compared to the clinical exam (mean score: 3.8 vs. 3.9; p = 0.370; OR 0.89; 95% CI 0.46 to 1.72; p = 0.87). Significantly fewer cases fell into the uncertain category with PoCUS than with clinical assessment (2 vs 12; p = 0.008). Repeat reduction was performed in 49 patients (41.2%). Repeat reduction led to a significant improvement (p < 0.001) in the PoCUS determined adequacy of reduction (mean score: 4.3 vs 3.1; p < 0.001). In this group, the odds ratio for adequate vs. uncertain or inadequate reduction assessment using PoCUS was 12.5 (95% CI 3.42 to 45.7; p < 0.0001). There was no significant difference in the assessment of reduction by PoCUS vs. radiograph.ConclusionsPoCUS-guided fracture reduction leads to repeat reduction attempts in approximately 40% of cases and enhances certainty regarding reduction adequacy when the clinical assessment is unclear.

LO062: Ultrasound-assisted distal radius fracture reduction

Introduction: Closed reduction of distal radius fractures (CRDRF) is a commonly performed emergency department (ED) procedure. The use of Point-of-care ultrasound (POCUS) to diagnose fractures and guide reduction has previously been described. The primary objective for this study was to determine if the addition of PoCUS to CRDRF changed the perception of successful initial reduction. This was measured by the rate of further reduction attempts based on POCUS following the initial clinical determination of achievement of best possible reduction. Methods: We performed a multicenter prospective cohort study, using a convenience sample of adult ED patients presenting with a distal radius fracture to 5 Canadian EDs. All study physicians underwent standardized PoCUS training for fractures. Standard clinically guided best possible fracture reduction was initially performed. PoCUS was then used to assess the reduction adequacy. Repeat reduction was performed if deemed indicated. A post-reduction radiograph was then performed. Clinician impression of reduction adequacy was scored on a 5 point Likert scale following the initial clinically guided reduction, and following each POCUS scan and the post-reduction radiograph. Results: There were 131 patients with 132 distal radius fractures. Twelve cases were excluded prior to analysis. There was no significant difference in the assessment scores for reduction success by PoCUS vs. clinical assessment (Median scores 4 vs.4; p=0.370;) or in the odds ratio of successful reduction (0.89; 95% CI 0.46 to 1.72; p=0.87). Significantly fewer cases fell in the uncertain category with POCUS than with clinical assessment (12 vs 2; p=0.008). Repeat reduction was performed in 49 patients (41.2%). In this group, the odds ratio for adequate reduction assessment post-PoCUS to pre-PoCUS was 12.5 (95% CI 3.42 to 45.7; p&lt;0.0001). There was no significant difference in the assessment of reduction by PoCUS vs. radiograph. Conclusion: PoCUS guided fracture reduction leads to repeat reduction attempts in approximately 40% of cases, and enhances certainty regarding reduction adequacy when clinical assessment is unclear.

Risk factors for redisplacement in pediatric distal radius fractures after closed reduction and cast immobilisation

Introducation: Pediatric distal radius fractures are one of the most common fractures that we see in our practice. The primary modality of treatment of the displaced fractures of distal radius in children is closed reduction and immobilization in cast. Loss of alignment in cast after an acceptable reduction is common. Twenty one to fifty percent rates of redisplacement in cast after acceptable initial reduction have been reported in literature. Methods: This prospective study included 58 fractures of distal radius and distal third shaft of radius in 57 children with radiologically open physis. Age, gender, initial displacement, associated fracture of the ulna, adequacy of reduction, cast index and gap index were evaluated as possible risk factors for redisplacement in cast. Results: A redisplacement rate of 34.48%was found in distal radius fractures of children after acceptable initial closed reduction and immobilization in cast. Initial complete displacement, degree of initial translation in coronal and sagittal plane, degree of initial angulation in the coronal plane, associated fracture of the ulna, non anatomical initial reduction and cast index were found to be significant risk factors for redisplacement. Age, gender, initial angulation in the sagittal plane and gap index were insignificant risk factors. Conclusion: Distal radius fractures in children have high rate of redisplacement in cast. Fractures with initial complete displacement, fractures with associated fracture of ulna and non-anatomically reduced fractures should either be treated by primary closed reduction and percutaneous pinning or must be followed very carefully in cast treatment. Cast index rather than gap index is a better predictor of loss of reduction in cast.

Postoperative radiographs after open reduction and internal fixation of mandibular fractures: clinical need or unnecessary radiation?

Postoperative radiographs are conventionally taken after open reduction and internal fixation (ORIF) of mandibular fractures, but routine radiographic exposure in patients who have no clinical signs may not be justified. To find out whether radiographs influence immediate postoperative management, and whether they can be used to predict long-term complications, we retrospectively reviewed the radiographs and case notes of 92 patients who had ORIF of isolated mandibular fractures between June 2010 and June 2012. We evaluated them for the adequacy of reduction and fixation using locally agreed criteria, and correlated them with immediate and long-term outcomes as recorded in the case notes. Eleven patients had complications, usually infection. All 4 patients who required repeat ORIF had worrying signs and symptoms despite the immediate postoperative radiograph looking favourable. The radiographs of 7 patients looked unfavourable, but no patient required another operation, and none developed complications. Routine postoperative radiographs after ORIF of mandibular fractures seem to have little value in the management of patients, as the decision to reoperate is based on clinical signs rather than radiographic appearance, and radiographic appearance is not associated with long-term outcomes. Our findings suggest that radiographs are valuable only in patients with clear clinical indications and, in view of the risk and cost of radiation, we question their continued use.

Open reduction and internal fixation of calcaneus fractures through a sinus tarsi approach

INTRODUCTION: The wound complication rate for open reduction and internal fixation of calcaneus fractures through the extensile approach is 30%. Due to this high rate of wound complications, many surgeons prefer conservative management. If post-traumatic arthritis develops, the clinical results of a subtalar fusion are better if the posterior facet is reduced and the shape of the calcaneus restored. The sinus tarsi approach utilises a much smaller incision and indirect reduction techniques limiting the need for a large incision while still providing good exposure of the posterior facet for anatomic reduction The purpose of this study is to present the technique for open reduction and internal fixation through a sinus tarsi approach, to assess the adequacy of reduction and the complication rate. METHODS: A retrospective chart and X-ray review was performed of all patients who had an open reduction and internal fixation of the calcaneus performed since 2013. We report on the interim results of the adequacy of reduction and maintenance thereof and the incidence of wound complications. Follow-up was for a minimum of 6 weeks RESULTS: Twelve procedures were performed in this time. The Bohler's angle improved from a median of 12° pre-operatively to 28.5° (p=0.002) post-operatively. The angle of Gissane improved from a median of 125° to 110° (p=0.0001). Two patients had minor wound complications, both of which were managed without surgery, using dressings for 10 to 12 days CONCLUSION: Open reduction and internal fixation of calcaneus fractures through a sinus tarsi approach allows adequate reduction with a low incidence of wound complications

Percutaneous screw fixation of unstable ankle fractures in patients with poor soft tissues and significant co-morbidities.

We describe a minimally invasive technique to stabilise unstable ankle fractures by inserting a 100mm screw up the fibula medullary canal along with percutaneous screw fixation of the medial malleolus if required. This technique is utilised in patients with poor soft tissues and significant co-morbidities where the fracture cannot be adequately controlled by a cast alone. Retrospective review of 23 patients the average age being 70 years (29-89) and 74% had significant co-morbidities. Postoperative radiographs were examined for adequacy of reduction using the method described by Mclenna and Ungersma. Patient based functional and health questionnaires were performed, reviewed and scored. Six patients were lost during the follow-up period due to death caused by issues unrelated to the ankle fracture. There were no reported intraoperative complications, no postoperative wound infections and no non-unions. There was two complications one loss of fixation, and another required removal of the screw due to irritation. Radiographic reduction was good in 52%, fair in 44% and poor in 4%. Patient questionnaire results were 70 (20-100) for the Abbreviated Olerud and Molander score and the SF-12 physical component score was 42 and mental component was 44. With appropriate patient selection percutaneous screw fixation is an excellent technique supplementing cast immobilisation of unstable ankle fractures with poor soft tissues.

Ultrasound-guided pediatric forearm fracture reductions in a resource-limited ED

BackgroundPediatric forearm fractures are a common presentation in emergency departments in Papua New Guinea. Often these children undergo “blind” closed reduction with reduction adequacy assessed by standard radiographs. This study aims to demonstrate the safety and efficacy of ultrasound (US) in guiding closed reduction of pediatric forearm fractures in a resource-limited setting. MethodsWe recruited consecutive children with closed forearm fractures requiring reduction. A US scanner was used to visualize and aid fracture reductions. The outcome measures were the rate of successful reductions (ie, adequate alignment without the need for a second procedure or further surgical intervention), length of stay in hospital, and adverse events during each procedure and at follow-up after 6 weeks. ResultsOf 47 children recruited, there were 44 (94%) successful reductions, whereas 3 (6%) required repeated reduction. The mean (SD) length of stay in hospital of the successful cases was 8.77 (3.66) hours. Two patients had tight plaster casts during early follow-up which were immediately addressed. Of the 44 successful cases, only 38 were retrieved for the final review. No further adverse events were observed in the latter. ConclusionsThis small-scale study has demonstrated the safe and efficacious use of US-guided close reduction of pediatric forearm fractures in a low-resource setting. Using US, real-time visualization of reduction efforts can reassure the clinician in decision making, thus reducing the rate of repeated reductions and allowing shorter hospital stay.
