Comparison of the Reliability of Three Scoring Systems Used to Decide Whether to Apply Cement in Hip Arthroplasty Among Fracture Patients and the Effect of Surgical Experience: The Spotorno, Dorr, and Canal Flare Indices.

BACKGROUND: No consensus has been reached regarding the best index to decide whether to use cement during hip replacement surgery. Therefore, this study compared the reliability of three frequently used scoring systems. The secondary purpose was to evaluate the effect of surgical experience on the decision to use cement. METHODS: Anteroposterior radiographs of 60 hips were assessed by four orthopedic surgeons and four orthopedic residents. The observers were asked to make measurements using the Spotorno criteria, the Dorr index, and the canal flare index, and to decide whether to use a cemented or cementless femoral stem. The same X-rays were sent to all participants, in a different order, 4 weeks later, for a second evaluation. The SPSS software (version 24.0) was used for the statistical analysis. Intraobserver agreement was determined for all observers via the intraclass correlation coefficient (ICC), and interobserver reliability was calculated using the weighted kappa (κ) statistic. RESULTS: The average age of the patients were 73.1 ± 12.1 years. Thirty-three (55%) patients were female and thirty-two (53.3%) had fractures on the right side. Intraobserver agreement was "excellent" for all participants according to the Spotorno criteria. The canal flare index had the lowest intra-observer agreement. The highest interobserver agreement was found using the Spotorno criteria. CONCLUSION: The intra- and interobserver reliabilities of the Spotorno criteria were higher than those of the Dorr index and the canal flare index. The Spotorno criteria was more useful for deciding between cemented and un-cemented hip arthroplasty.

Alterations in serum IL-6 levels in traumatized pediatric patients: A preliminary study for second hit concept.

BACKGROUND: The inflammatory response of pediatric patients to multiple injuries can be monitored by serum interleukin-6 levels. The aim of this study was to investigate the severity of the inflammatory response accordingly interleukin-6 (IL-6) which have not been evaluated before. METHODS: There were 30 patients with an isolated long-bone fracture in group 1 and 49 patients with multi-system injury with at least a fracture in group-2. In group-2 were divided into two subgroups according to MISS (cut-off value = 17). Group-3 was composed of 100 healthy children as the control group to determine the normal range of serum IL-6 levels. In group-2, blood samples were taken on the 3rd, 5th, and 10th days, and if the patient was operated, additional samples were taken before the surgery and on the postoperative 1st, 5th, and 10th days. The relationship between trauma severity and serum IL-6 levels was analyzed statistically. RESULTS: Mean serum IL-6 levels were 16.1, 46.4, 74.2 and 8.6 pg/mL respectively (group-1, -2A, -2B, and -3). There was a moderate correlation between MISS and IL-6 (p < 0.001). In group-2A, mean serum IL-6 levels were 13.9 pg/mL on the 3rd day and 9.1 on the 10th day. In group-2B they were 15.4 and 4.7 pg/mL, respectively. Also, for the patients undergoing surgically in group-2A, they were 36.0 pg/mL before the surgery, 33.2 on the 1st day, and 6.0 on the 10th day. For group-2B, they were 39.3, 37.4, and 7.9 pg/mL, respectively. CONCLUSION: It was determined that serum IL-6 levels were significantly increased with increasing trauma severity. Systemic inflammation specified by IL-6 could decrease to almost normal on the 3rd day, and regress to normal on the following days. The concept of "second hit impact following surgical procedure" may also be kept in mind in children as in adults considering these alterations.

Evaluation of clinical findings and neurofibromatosis type 1 bright objects on brain magnetic resonance images of 60 Turkish patients with NF1 gene variants.

Neurofibromatosis type 1 (NF1) is caused by mutations in the NF1 gene. This retrospective study aims to evaluate the clinical manifestations and brain magnetic resonance images (MRI) analysis in 60 genetically confirmed NF1 patients. The results of next-generation sequencing (NGS), Sanger sequencing, and MLPA of NF1 gene were evaluated. A total of 54 different variants were identified. Fourteen out of them were novel variants (25.9%). Patients who complied with NIH criteria had most frequently frameshift variants (11/32 patients), and those with only CALMs had missense variants (9/28 patients). Neurofibromatosis type 1 bright objects (NBOs) on T2-weighted MRI were detected in 42 patients (42/56; 75%). These brain lesions were detected mostly in basal ganglia and in cerebellar vermis. NBOs were detected more in the patients who complied with NIH criteria (80.6%) compared to those who were only CALMs (68%). While frameshift variants (33.3%) were the most common type variants in the patients who had NBOs, the most common variants were splicing (35.7%) and missense (35.7%) variants in the patients whose MRIs were normal. Frameshift variants (11/28 patients; 39.3%) were the most common in the patients with more than one brain locus involvement. Therefore, we consider that frameshift variants may be associated with increased incidence of NBOs and involvement of more than one brain locus. In addition, NBOs may occur less frequently in the patients with splicing variants. To our knowledge, this is the first study evaluated the relationship between NF1 gene variants and NBOs. Future studies may help us understand the etiology of NBOs.

Jaffe Lichtenstein Type of Polyostotic Skeletal Fibrous Dysplasia With the Involvement of Cranial Bones.

ABSTRACT: Fibrous dysplasia (FD), a benign fibro-osseous bone tumor commonly involving the craniofacial region, presents a wide spectrum of radiographic patterns. When FD lesions are suspected, various imaging modalities and histopathologic analyses may be required to reach a firm diagnosis. Here, the authors report the case of a 10-year-old male patient presenting with polyostotic type of FD with follow-up data for the next 9 years. The patient showed involvement of cranial bones and bilateral femurs, with skin pigmentation and no endocrine disease, consistent with the diagnosis of Jaffe Lichtenstein disease. The craniofacial radiographic features obtained with computed tomography and cone-beam computerized tomography are documented in this article.

Intra- and inter-observer reliability of Laredo classification system in Legg-Calvé-Perthes Disease.

The purpose of the current study was to investigate intra- and inter-observer reliability of arthrographic Laredo classification system in Perthes disease. Forty-seven patients were included in this cross-sectional descriptive study. Patients' age, gender, physical findings and hip arthrographs were collected from hospital medical records. Two different sets of power point slides were prepared in which the order of cases was randomized and blinded. Observers were divided into three groups according to their surgical experience (9 residents, 10 seniors, 10 pediatric orthopedists), and they assessed two times 1 month's intervals. Statistical analysis was performed by using the SPSS v21. Inter- and intra-observer reliabilities were calculated using intra-class correlation coefficient, weighted kappa and percentage agreement. Percentage agreement of Laredo classification was about 50% for all groups (residents, seniors and pediatric orthopedists); intra-observer reliabilities were excellent, excellent and fair, respectively. Inter-observer reliability of Laredo classification for each set was found to be excellent for all groups. Length of experience did not correlated significantly with the level of intra-observer agreement. As a conclusion, our results showed that Laredo's arthrographic classification system's intra-observer reliability is at least at a fair level and inter-observer reliability is at an excellent level. We believe that this classification system is valuable for an orthopedic surgeon who deals with the treatment of Perthes disease.

Do Patients With Acute Isolated Pubic Ramus Fractures Have To Be Hospitalized?

A total of 129 patients were included in the study. Haemoglobin levels on admission and at 24 hours were evaluated. Radiographs and computed tomography of the pelvis were also evaluated. The patients were divided into subgroups, according to the accompanying occult posterior pelvic injuries, whether they received anticoagulant-antiaggregant treatment, the number of pubic ramus fractures (single or multiple), the level of energy (low or high) and the zone(s) of the fracture(s). The mean haemoglobin decrease was 1.21 g/dL. Forty-six of the patients were under anticoagulant or antiaggregant treatment. Fifty-one of the fractures occurred due to low energy trauma. Posterior ring injuries were observed in 75 of the patients. Haemoglobin level decreases were statistically significant in injuries with high energy trauma aetiology, in patients using antiaggregant or anticoagulant and in fractures of the lateral half of the superior pubic ramus. It is important to follow all pubic ramus fractures closely because, even in low energy trauma, haemoglobin levels could decrease significantly. We recommend hospitalization to monitor this group of patients.

Accuracy of bedside ultrasonography for the diagnosis of finger fractures.

OBJECTIVE: Diagnosis of bone fractures by ultrasonography is becoming increasingly popular in emergency medicine practice. We aimed to determine the diagnostic sensitivity and specificity of point-of-care ultrasonography (PoCUS) compared with plain radiographs in proximal and middle phalanx fractures. METHODS: Between August 2012 and July 2013, adult patients presenting to our emergency department with a possible (by clinical evaluation) proximal or middle phalanx fracture of finger were invited to participate in this prospective cohort study. From those granting consent to participate, anteroposterior and lateral radiographs were obtained. PoCUS was then performed by emergency physicians blinded to the radiograph results. The criterion standard test for diagnosis was radiograph interpretation by an orthopedic surgeon blinded to the ultrasonographic findings. RESULTS: During the study period, 212 patients with an injury to the proximal or middle phalanx presented to the emergency department. Of these, 93 patients met exclusion criteria; thus, data were analyzed from the remaining 119 patients. Fracture prevalence was 24.3%. Diagnostic sensitivity of PoCUS was 79.3% (95% confidence interval [CI], 59.7%-91.2%), specificity was 90% (95% CI, 81.4%-95.0%), positive predictive value was 71.8% (95% CI, 53.0%-85.6%), negative predictive value was 93.1% (95% CI, 85.0%-97.1%), positive likelihood ratio was 7.93 (95% CI, 4.15-15), and negative likelihood ratio was 0.23 (95% CI, 0.11-0.47). CONCLUSION: Emergency physician-performed PoCUS was moderately sensitive and specific for diagnosing proximal and middle phalanx fractures.

Which factor is most important for occurrence of cutout complications in patients treated with proximal femoral nail antirotation? Retrospective analysis of 298 patients.

INTRODUCTION: Mechanical complications, such as cut-out of the head-neck fixation device, are the most common causes of morbidity after trochanteric femur fracture treatment. The causes of cut-out complications are well defined in patients who are treated with sliding hip screws and biaxial cephalomedullary nails but there are few reports about the patients who are treated with proximal femoral nail antirotation. AIM: The purpose of this study was to evaluate the most important factor about occurance of cutout complication and also to evaluate the risks of the combination of each possible factors. PATIENTS AND METHODS: Overally 298 patients were enrolled in the study. Medical records were reviewed for patients' age, fracture type, gender, anesthesia type and occurance of cut-out complication. Postoperatively taken radiographs were reviewed for tip-apex distance, obtained collo-diaphyseal angle, the quadrant of the helical blade and Ikuta reduction subgroup. The most important factor (s) and also predicted probability of cut-out complication was calculated for each combination of factors. RESULTS: Cut-out complication was observed in 14 patients (4.7 %). The most important factor about occurrence of the cut-out complication was found as varus reduction (p: 0.01), the second important factor was found as implantation of the helical blade in the improper quadrant (p: 0.02). Tip-apex distance was found as third important factor (p: 0.10). The predicted probability of cut-out complication was calculated as 45.6 % when whole of the four surgeon dependent factors were improperly obtained. CONCLUSION: Althought obtaining proper tip-apex distance is important to prevent cutout complication in these fractures, if the fracture is not reduced in varus position and helical blade is inserted in the proper quadrant, possibility of cut-out complication is very low even in the patients with high tip-apex distance.

Medial percutaneous hemi-epiphysiodesis improves the valgus tilt of the femoral head in developmental dysplasia of the hip (DDH) type-II avascular necrosis.

BACKGROUND AND PURPOSE: Avascular necrosis (AVN) is a major cause of disability after treatment of developmental dysplasia of the hip (DDH), leading to femoral head deformity, acetabular dysplasia, and osteoarthritis in adult life. Type-II AVN is characterized by retarded growth in the lateral aspect of the physis or by premature lateral fusion, which produces a valgus deformity of the head on the neck of the femur. We investigated the effect of medial percutaneous hemi-epiphysiodesis as a novel technique in the treatment of late-diagnosed type-II AVN. PATIENTS AND METHODS: 9 patients (11 hips) with a diagnosis of type-II AVN who underwent medial percutaneous hemi-epiphysiodesis after the surgical treatment for DDH were included in the study. 10 patients (12 hips) with the same diagnosis but who did not undergo hemi-epiphysodesis were chosen as a control group. Preoperative and postoperative articulotrochanteric distances, head-shaft angles, CE (center-edge) angles, and physeal inclination angles were measured. The treatment group underwent medial hemi-epiphysodesis at a mean age of 8 years. The mean ages of the treatment group and the control group at final follow-up were 14 and 12 years respectively. The mean duration of follow-up was 5.7 years in the treatment group and 8.3 years in the control group. RESULTS: Preoperative articulotrochanteric distance, head-shaft angle, and functional outcome at the final follow-up assessment were similar in the 2 groups. However, preoperative and postoperative CE angles and physeal inclination angles differed significantly in the treatment group (p < 0.05). The final epiphyseal valgus angles were better in the treatment group than in the control group (p = 0.05). The treatment group improved after the operation. INTERPRETATION: Medial percutaneous epiphysiodesis performed through a mini-incision under fluoroscopic control is a worthwhile modality in terms of changing the valgus tilt of the femoral head.

The accuracy of bedside ultrasonography as a diagnostic tool for the fifth metatarsal fractures.

OBJECTIVES: Musculoskeletal ultrasonography is a technique that is becoming more popular in diagnosing injuries of emergency department (ED) patients especially for the diagnosis of fractures. In this study, we determined the reliability of ultrasonography for the diagnosis of fractures of the fifth metatarsal. METHOD: This is a prospective blind study. Patients over 14 years old who were admitted to the ED with acute foot injury and who had tenderness on the fifth metatarsal were consecutively enrolled into the study. A bedside ultrasonography exam was performed by an emergency physician, and antero-posterior and oblique views were obtained. X-rays were blindly evaluated by an orthopedic surgeon and were considered to be the gold-standard for diagnosing fractures. In patients with noncomminuted fractures, bone displacement was measured by both radiologically and sonographically. RESULTS: Eighty-four patients were included in this study. Their mean age was 36.0, and 42.9% were male. Fractures were diagnosed by both x-ray and ultrasonography in 33 patients. In one patient, the x-ray was positive for fracture, while ultrasonography yielded a negative result. For the fractures of fifth metatarsal, the diagnostic sensitivity of ultrasonography was 97.1%, the specificity was 100%, the positive likelihood ratio was infinity, the negative likelihood ratio was 0.03. Mean displacement was 1.2 ± 0.7 mm with x-ray and 1.8 ± 1.5 mm with ultrasonography. The intraclass correlation coefficient of displacement measured by x-ray and ultrasonography was κ: 0.388. CONCLUSION: Ultrasonography is a reliable diagnostic tool for acute fifth metatarsal fractures.

How are outcomes affected by performing a one-stage combined procedure simultaneously in bilateral developmental hip dysplasia?

PURPOSE: The aim of this study was to compare the outcomes of one-stage combined surgical treatment in children of unilateral and bilateral developmental hip dysplasia diagnosed after walking age. METHODS: We reviewed 24 patients who underwent one-stage combined surgery for DDH diagnosed after walking age. Group I consisted of 12 patients with bilateral disease who underwent bilateral operation at one operative setting. Group II consisted of 12 patients with unilateral disease. Pre-operatively the hips were classified according to Tönnis classification. Acetabular dysplasia was evaluated by measuring acetabular index (AI) angles pre-operatively. The acetabular improvements with time regarding AI was noted immediately postoperatively, every six months, and at the final follow-up examination. RESULTS: Mean follow up of the bilateral group I and group II were 54.8 months (range 20-84 months) and 52.6 months (24-80), respectively. There were no statistically significant differences between immediate postoperative and final follow up acetabular index improvement rates in both groups. Also there was no significant difference when both hips were compared in group I. The clinical final outcome of both groups and within group I was similar. CONCLUSIONS: Simultaneous combined surgery is a challenging but worthwhile procedure for late diagnosed patients with bilateral DDH. The short-mid term outcomes of the procedure are encouraging.

Intraobserver and Interobserver Reliability of the Computed Tomography-Based Classifications Used in Posterior Malleolar Fractures: The Haraguchi and Bartonícek-Rammelt Classifications.

BACKGROUND: Three main computed tomography (CT)-based classification systems have been defined and used for posterior malleolar fractures. The intraobserver and interobserver reliability of two of these systems has never been investigated. The aim of this study was to investigate the intraobserver and interobserver reliability of the Haraguchi (HC) and Bartonícek-Rammelt (BRC) classifications. METHODS: Axial and sagittal CT sections and three-dimensional reconstruction images of 60 fractures were evaluated twice by six observers at a 6-week interval. Cohen κ values for intraobserver reliability and Fleiss κ values for interobserver reliability were calculated. RESULTS: The interobserver reliability of the HC was fair in both assessments (Fleiss κ: 0.263 and 0.249 for the first and second evaluations, respectively). The interobserver reliability of the BRC was moderate in both evaluations (Fleiss κ: 0.535 and 0.447, respectively). The intraobserver reliability values (Cohen κ) of the HC were determined to be between 0.532 and 0.927 for the six observers. These values indicated moderate agreement for one observer, substantial for four, and very good for one. Intraobserver reliability values for the BRC were determined to be between Cohen κ of 0.626 and 0.884. Based on these values, the BRC's intraobserver reliability indicated substantial agreement for two observers and very good for four observers. CONCLUSIONS: Intraobserver and interobserver reliability values of the BRC were higher than those of the HC.

How Reliable Are Digital Radiographs for Evaluating Intra-articular Displacement in Ankle Epiphyseal Fractures: Can Computed Tomography Be Eliminated?

BACKGROUND: The amount of intra-articular displacement of the fracture is the main issue when deciding the treatment method between conservative or surgical means in intra-articular fractures. In this study, we aimed to determine the intraobserver and interobserver reliability of measuring intra-articular displacement and to compare the digital radiographic and computed tomographic (CT) evaluations in distal tibia intra-articular epiphyseal fractures. METHODS: Thirty-seven patients with digital radiography and CT scans were included in the study. Four sets were prepared with these images. Two of four sets were prepared as ankle radiographs, and the other two sets were prepared with CT scan views. Five observers were asked to measure the intra-articular displacement of the fractures in millimeters and also to make a decision between displacement amounts over or under 2 mm. Intraclass correlation coefficient scores were calculated for evaluation of intraobserver reliability, and Fleiss kappa values were calculated for interobserver reliability evaluations. A value greater than 0.75 was accepted as excellent agreement; 0.75 to 0.40 as intermediate to good agreement; and below 0.40 as poor agreement. RESULTS: There were 15 Salter-Harris type 3, 13 Salter-Harris type 4, seven triplanar, and two Tillaux-Chaput fractures. Both intraobserver and interobserver reliabilities were slightly higher for CT scan evaluations. Amounts of displacement were found to be measured higher after CT scan evaluations other than radiographs. After the measurement of joint displacements on CT scans, it was observed that the measurements found below 2 mm on the digital radiograph measurement changed to greater than or equal to 2 mm in 16.4% of the patients. CONCLUSIONS: This study confirmed that digital radiographs cannot replace CT scans for the measurement of intra-articular displacement in ankle epiphyseal fractures.

Analysis of the factors that are important in re-displacement in pediatric diaphyseal femur fractures treated with a spica cast.

BACKGROUND: There is no detailed data on the factors affecting the re-displacement in pediatric femoral fractures treated with closed reduction and early spica casting. This study aimed to investigate the factors effective in re-displacement in pediatric diaphyseal femur fractures (PDFF) treated with spica casting. METHODS: In all, 151 displaced PDFF were evaluated retrospectively. Demographic data of the patients were evaluated. Type of fractures, anteroposterior and lateral angulations, amount of shortening, translation ratio, cast index (CI), gap index (GI), and three-point index (TPI) measurements were evaluated radiologically. Thigh flexion angle (TFA) and knee flexion angle (KFA) were measured. After casting, angulation of more than 10° in any plane and a shortening of more than 10 mm was accepted as re-displacement. Binary logistic regression analysis was used to evaluate the risk factors of re-displacement. Receiver operating characteristic analysis was performed for TFA and KFA. RESULTS: Re-displacement was detected in 40 patients (26.5%). Transverse type fracture (p = 0.001), TFA ˂71.4° (p <0.001), and KFA ˂52.6° (p = 0.002) were found to be statistically significant factors on re-displacement. It was determined that the combination of transverse femoral fracture and TFA ˂71.4° increased the probability of re-displacement by approximately 14 times. It has been observed that indices such as CI, GI, and TPI were not effective in predicting the risk of re-displacement. CONCLUSION: When treating a PDFF with spica casting, one should be aware of re-displacement if the fracture type is transverse, TFA is ˂71.4°, and KFA is ˂52.6°. LEVEL OF EVIDENCE: Level III, prognostic.

Does the size of Thurston-Holland fragment have an effect on premature physeal closure occurrence in type 2 distal tibia epiphyseal fractures?

The purpose of this study was to investigate the possible effect of Thurston-Holland fragment (THF) size on the development of premature physeal closure (PPC) in distal tibia type 2 epiphyseal injuries. Fifty-eight fractures in 57 patients with a minimum follow-up period of 12 months were included. For statistical analysis, sex and age of the patient, number of reduction attempts, percentage of THF base relative to physis length on anteroposterior or lateral radiograph, maximal initial and postreduction displacement amount, presence of accompanying fibula fracture and trauma mechanism were evaluated. PPC was observed in 12 fractures (20.7%). An increased amount of initial displacement, increased number of reduction attempts and passing the physis with three Kirschner wires were determined as statistically significant factors for PPC occurrence (P = 0.011, 0.011 and 0.005, respectively). The THF percentage was not found to be an important factor for the occurrence of PPC. In males, THF size was less than 50% more frequently than that in females (P = 0.013). THF size had no significant effect on PPC occurrence after distal tibial epiphyseal fractures.

The influence of anesthesia-body mass index and chronicity of the injury on the reliability of diagnostic tests for anterior cruciate ligament rupture.

This study aimed to analyze the accuracy and interobserver reliability of the four common diagnostic tests for anterior cruciate ligament (ACL) rupture. The effect of anesthesia, chronicity of the injury and patient's body mass index (BMI) on the reliabilities was also assessed. Patients who underwent arthroscopic knee surgery were examined before the surgery and under anesthesia by three observers categorized based on their experience levels. One hundred two patients were evaluated to determine the accuracy of these tests. Sixty-two patients with ACL rupture were further examined to assess the effect of BMI (≤25 kg/m2, or >25 kg/m2) and chronicity (≤4 or >4 weeks) of the injury on reliabilities with using the Fleiss kappa method. The Lachman test performed under anesthesia had the highest sensitivity (100%, 100%, and 96.7%). In contrast, pivot shift and lever sign tests had the lowest sensitivity both in awake (24.2%, 17.7%, 8.1% and 37.1%, 33.8%, 29%) and anesthetized condition (75.8%, 75.8%, 67.7% and 41.9%, 43.5%, 40.3%). Specificities of the tests except pivot shift were negatively affected when performed under anesthesia. The reliability of the anterior drawer test was perfect under anesthesia. The lever sign test had the highest reliability in the awake condition in patients with a BMI of >25 kg/m2. Furthermore, the reliabilities of the anterior drawer, Lachman, and pivot-shift tests in awake condition were found to be increased in patients with a chronic injury. Finally, the examiner's experience is not important for the physical diagnosis of ACL rupture.

Ankle Joint Injuries Accompanying Fifth Metatarsal Base Fractures.

BACKGROUND: Fifth metatarsal base fractures are the most commonly seen fractures of the foot. Ankle sprains occur with inversion and plantarflexion mechanisms, similar to most fifth metatarsal base fractures. We sought to investigate the possible ankle injuries that accompany fifth metatarsal base fractures. METHODS: A hospital's digital database was searched for the International Classification of Diseases, Tenth Revision codes for metatarsal bone fractures (codes S92.30 and S92.35) between January 2015 and January 2018. Thirty-nine patients with fifth metatarsal base fracture who underwent ankle magnetic resonance imaging (MRI) within 14 days of injury were included in the study. The MRI findings were evaluated, and comparisons were performed according to fracture zone, sex, and age. RESULTS: The most common MRI finding was talocrural joint effusion, which was observed in 28 patients (71.8%). Bone marrow edema was observed in 16 patients (41.0%). Chondral injury at the medial dome of talus was observed in three patients (7.7%). Grade 1 ligament sprain was observed in six patients (15.4%): two in the lateral ligament and four in the deltoid ligament. CONCLUSIONS: Although most fifth metatarsal base fractures and ankle sprains occur as a result of a common mechanism, physical examination findings and patients' complaints are very important. Routine MRI should be unnecessary for most patients. If a patient with a fifth metatarsal base fracture has complaints about the ankle joint, one should be aware of bone marrow edema, which was observed in 41.0% of the study population.

Instant messaging application usage for clinical consultation among orthopedic surgery residents in Turkey: A survey study.

OBJECTIVE: This study aimed to determine the characteristics of instant messaging application (IMA) usage for clinical consultation among orthopedic residents in Turkey and to explore their experiences and opinions concerning potential legal problems. METHODS: A questionnaire titled "Instant messaging for consultation among orthopedic surgeons" consisting of 21 questions was applied to orthopedic surgery residents, and the results were analyzed. The questions were designed to obtain information on 4 categories: 1) demographics and professional experience, 2) attitudes on the use of cellular phones, 3) IMA usage for clinical consultation purposes, and 4) problems and comments on smartphone application usage for clinical consultation purposes. The participants who had no experience with a smartphone or IMA usage were excluded at the final analysis. RESULTS: A total of 860 orthopedic residents (849 males [98.7%]; mean age=28.6 years; age range=22-44 years) participated in the survey (participation rate: 97.3%). The distribution of residency years was as follows: 1st year, 27%; 2nd year, 21.4%; 3rd year, 18.4%; 4th year, 17.4%; and 5th year, 49.9%. The most frequently used IMAs were WhatsApp (99.3%), Facebook Messenger (14.8%), Viber (8%), and Tango (1.3%). The rate of IMA usage for consultation was 95.3%. The most common reasons to prefer IMAs for consultation were being "fast" and "easy," but only 26.3% of the residents reported that they prefer the use of IMAs because they find them "reliable." Moreover, 41.7% of the respondents reported that they had an experience of misdiagnosis owing to the use of IMAs; 81.2% of the participants used the personal information of the patients during the consultation; 57.6% of the respondents considered that legal problems may arise because of the use of IMAs during the consultation; and 51.4% believed that an electronic platform, solely for consultation purposes, is required. CONCLUSION: This survey has shown that it is necessary to make some legal regulations regarding the use of IMAs for consultation purposes and to develop applications only for medical consultation purposes. Most of the trainees make decisions using IMAs without a proper examination, putting the patients at the risk of misdiagnosis. Moreover, the confidentiality of the patient's personal information appears to be in danger when IMAs are used. LEVEL OF EVIDENCE: Level IV, Diagnostic Study.

Cornelia de Lange syndrome: A rare case, presented with unilateral pes equinovarus.

Cornelia de Lange syndrome is a genetic disorder with multiple system abnormalities. It is especially characterized by typical facial appearance and hirsutism. Growth and mental retardation, gastrointestinal, cardiovascular, and orthopedic abnormalities are other important features of this syndrome. In this case, we present a rare manifestation of Cornelia de Lange syndrome with a unilateral pes equinovarus deformity without other more specific orthopedic manifestations. Ponseti method's was applied as the initial procedure. Afterwards, complete subtalar release was performed. After four years follow-up, clinical and radiological results were satisfactory. Unilateral pes equinovarus deformity may be a part of this syndrome as well as a sporadic presentation. The discrimination is important for anesthetic procedures and surgical outcomes.

The Effect of Clinical Knowledge and Surgical Experience on Treatment Choice in Legg-Calve-Perthes Disease: Intra-observer and Inter-observer Reliability Study.

AIM: The aim of this study was to evaluate standardized hip radiographs, arthographs, demographic characteristics, physical examination findings, and their effects on treatment choices in leg-calve-perthes disease (LCPD). Intraobserver and interobserver realibility between orthopaedic residents, orthopaedic surgeons, and paediatric orthopaedic surgeons were also investigated. MATERIALS AND METHODS: 47 LCPD patients were included this cross-sectional study. Six separate presentations including different variabilities (clinical findings, standard radiographs, and arthrographs) were evaluated by three different groups (residents, surgeons, paediatric orthopaedic surgeons) and were sent to the observers every other month by hiding patients' personal information. Seven different treatment modalities were introduced for the best treatment modality. Intraobserver and interobserver reliability in these three groups were examined. Percentage aggreement (PA) and intraclass correlation coefficients (ICC) tests were used for this purpose. RESULTS: Treatment PA rates between presentations were 29.5-53.6% in residents, 38.3-60.4% in surgeons, and 39.1-59.8% in pediatric orthopaedic surgeons. Conservative methods were mostly preferred as treatment modality in all groups; followed by proximal femoral osteotomies. Pediatric orthopaedic surgeons preferred safe dislocation and femur head and/or neck reconstruction surgery 5-18 times more than residents and orthopaedic surgeons. Intraobserver reliability of treatment modalities was higher among the paediatric orthopaedic surgeons; the results were fair-good (0.483-0.763). Among residents and orthopaedic surgeons, ICC values were poor to good, respectively (- 0.080 to 0.636 and 0.263-0.643). Interobserver reliability among three groups was meanly good. CONCLUSION: As surgical experience increases, both the compliance rates of the treatment modalities and the intra- and inter-group reliability are increased. Knowledge of the demographic data and clinical findings of patients besides hip radiographs or arthrographs increase treatment compliance in paediatric orthopaedic surgeons, however, cause changes in treatment modalities in residents. As surgical experience increases, more difficult surgeries such as safe dislocation and femoral head/neck reconstruction are preferred.
