Purpose: Olecranon fractures are classified using the commonly accepted Mayo classification. Its reliability has been analyzed by means of radiographs. A CT scan is often obtained due to joint involvement. Purpose of this study was to evaluate the intra- and interobserver reliability of the Mayo classification based on CT examination. Methods: Radiographic and CT images of 20 olecranon fractures were classified by four surgeons at two time points 30 days apart. Intra- and interobserver reliability were assessed using kappa coefficients. Results: Mean intraobserver reliability between X-rays was substantial and between CTs almost perfect (0.76 and 0.82, respectively). Mean interobserver reliability was fair for X-rays and moderate for CTs (0.32 and 0.44, respectively). Conclusion: Despite the more detailed imaging compared with radiography only moderate interobserver reliability was found for the classification of olecranon fractures based on CT imaging. This might lead to inconsistent fracture classification in both scientific and clinical setting. [ABSTRACT FROM AUTHOR]

Background: Displaced olecranon fractures constitute a challenging problem for elbow surgeons. The purpose of this study is to evaluate the role of suture anchor fixation for treating patients with displaced olecranon fractures. Methods: A retrospective review was performed for all consecutive patients with displaced olecranon fractures treated with suture anchor fixation with at least 2 years of clinical follow-up. Surgical repair was performed acutely in all cases with nonmetallic suture anchors in a double-row configuration utilizing suture augmentation via the triceps tendon. Osseous union and perioperative complications were uniformly assessed. Results: Suture anchor fixation was performed on 17 patients with displaced olecranon fractures. Functional outcome scores were collected from 12 patients (70.6%). The mean age at the time of surgery was 65.6 years, and the mean follow-up was 5.6 years. Sixteen of 17 patients (94%) achieved osseous union in an acceptable position. No hardware-related complications or fixation failure occurred. Mean postoperative shortened disabilities of the arm, shoulder, and hand (QuickDASH) score was 3.8±6.9, and mean Oxford Elbow Score was 47.5±1.0, with nine patients (75%) achieving a perfect score. Conclusions: Suture anchor fixation of displaced olecranon fractures resulted in excellent midterm functional outcomes. Additionally, this technique resulted in high rates of osseous union without any hardware-related complications or fixation failures. Level of evidence: IV. [ABSTRACT FROM AUTHOR]

Background Autosomal dominant polycystic kidney disease (ADPKD) is the most common genetic kidney disease and shows a wide phenotype. Only patients with rapid progression (RP) are included in clinical trials or are approved to receive disease-modifying drugs. This study aims at comparing different available predictive tools in ADPKD with the Mayo classification (MC) identification of rapid progressors based on high total kidney volume (TKV) according to age. Methods A total of 164 ADPKD patients were recruited retrospectively from a single centre. The performance of diverse tools to identify RP defined as being in MC categories 1C–1E was assessed. Results A total of 118 patients were MC 1C–1E. The algorithm developed by the European Renal Association–European Dialysis and Transplant Association Working Group on Inherited Kidney Disorders/European Renal Best Practice had a low sensitivity in identifying MC 1C–1E. The sensitivity and specificity of TKV to predict RP depend on the cut-off used. A kidney length of >16.5 cm before age 45 years has high specificity but low sensitivity. Assessing the MC by ultrasonography had high levels of agreement with magnetic resonance imaging (MRI) data, especially for 1A, 1D and 1E. The estimated glomerular filtration rate (eGFR) decline was very sensitive but had low specificity. In contrast, the Predicting Renal Outcome in Polycystic Kidney Disease (PROPKD) score was very specific but had poor sensitivity. Having hypertension before 35 years of age is a good clinical predictor of MC 1C–1E. Family history can be of help in suggesting RP, but by itself it lacks sufficient sensitivity and specificity. Conclusions The MC by ultrasonography could be an option in hospitals with limited access to MRI as it performs well generally, and especially at the extremes of the MC, i.e. classes 1A, 1D and 1E. The eGFR decline is sensitive but not very specific when compared with the MC, whereas the PROPKD score is very specific but has low sensitivity. Integrating the different tools currently available to determine RP should facilitate the identification of rapid progressors among patients with ADPKD. [ABSTRACT FROM AUTHOR]

Olecranon fractures are common in orthopedic wards and can be traumatic or pathological in origin. There are very few cases of bilateral olecranon fractures without any associated injuries to the long bones in the literature. We present a unique case of a young 21-year-old male who has an isolated bilateral olecranon fracture following a road traffic accident. The patient had a closed fracture of the ulna on both sides without any associated injuries or neurovascular compromise. Since the patient was young and had good muscle strength preoperatively, we planned fixation of both sides. The patient underwent open reduction and internal fixation with tension band wiring on the right side, which was his dominant side. The left side was operated on by open reduction and internal fixation with an anatomical plate. The patient was started on elbow range of motion on the right side from the second   postoperative day and started basic activities such as having food independently by the 10th day postoperatively. The physiotherapy was continued in a stepwise manner, and by the sixth week, the patient had a full range of motion on both sides. The patient had resumed his activities of daily living independently by the sixth   week following the surgery. Such cases are rare, and a case-based management plan must be devised for each patient, considering contributing factors such as age, bone quality, osteoporosis, underlying medical comorbidities, functional demands, and muscle strength. We demonstrated a good clinical and radiological outcome by using tension band wiring on the dominant side with a stable olecranon fracture and plating done on the non-dominant side, which had an unstable displaced olecranon fracture., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Olecranon fractures are common and usually treated operatively either by tension band wiring (TBW) or plate fixation (PF). The aim of this study was to assess early complications and reoperations and their predictive factors related to those operative methods. A retrospective analysis of all patients with an operatively treated olecranon fracture between 2007 and 2017 at Turku University hospital was performed. Reoperations, postoperative complications, and potential risk factors for these were recorded. A total of 434 patients (387 TBW and 47 PF) were identified. There was no statistically significant difference in the rate of early complications (49% vs. 62%, P =.262) or reoperations (38% vs. 53%, P =.079) between patients treated with TBW and PF. In the TBW group, the intramedullary placement of Kirschner (K)-wires predisposed patients to complications compared to transcortical placement of the K-wires according to multivariate analysis (odds ratio [OR] 1.94, P =.026). Younger age was associated with the frequency of reoperations, the odds decreasing 24% for every 10 years of age (P <.001). Further, patients with high-energy trauma mechanisms were reoperated more often compared to patients with low-energy trauma (OR 2.99, P =.002). Also, excellent postoperative reduction was associated with higher reoperation rate than good or fair reduction (OR 0.48, P =.033). There is a high risk of early complications and reoperations associated to both TBW and PF. Transcortical positioning of K-wires may reduce the rate of complications in TBW. [ABSTRACT FROM AUTHOR]

Background: The data on prevalence of extraintestinal manifestations (EIM) in ulcerative colitis (UC) are scanty and highly variable. Methods: Consecutive patients with UC were prospectively evaluated from November 2016 to August 2017. A detailed history was obtained and physical examination was done. Presence of EIM was confirmed by a consultant rheumatologist, ophthalmologist and dermatologist. Tests performed were hemogram, liver function test, abdominal ultrasound, slit lamp examination, X-ray and magnetic resonance imaging when deemed necessary. Results: A total of 227 patients with UC were enrolled in this study. The prevalence of EIM was 7.92%. Mucocutaneous (4.84%) manifestations were the commonest, followed by musculoskeletal (1.32%) and ocular (0.88%). Hepatobiliary (0.44%) and vascular (0.44) manifestations were present in equal frequency. History of appendicectomy was associated with EIM. Conclusion: The prevalence of EIM in UC was low in our study. History of appendicectomy was a risk factor for EIM. [ABSTRACT FROM AUTHOR]

Intravascular leiomyoma is an uncommon disease and depending of vascular involvement and anesthetic challenge. We review a case of a 53-year-old woman who underwent vena cava leiomyoma resection under cardiopulmonary bypass using deep hypothermic circulatory arrest (DHCA). Invasive hemodynamic and neurologic monitoring, transesophageal echocardiography, and viscoelastic coagulation test were used during the procedure. Total surgical resection was accomplished with no complications and the patient was extubated 2 days after surgery without cardiac or neurologic deficit. Although uncommon, level IV intravascular leiomyoma surgery is a challenge because the total resection needs DHCA, prolonged cardiopulmonary bypass and aortic cross-clamp times. These conditions expose the patient to the risk of coagulopathy, low cardiac output syndrome, and neurologic deficit.

Olecranon fractures constitute 10% of traumatic fractures in the upper limb however; bilateral traumatic olecranon fracture is rare. They follow a fall on a flexed elbow or strike on the point of the elbow or in patients with other systemic pathology such as Rheumatoid arthritis or sarcoidosis. Bilateral fractures with posterior radio humeral dislocation are even rarer and offer a management dilemma. We report one case of traumatic bilateral olecranon fractures with posterior radio-humeral dislocation without any concomitant systemic disease. After imaging studies, the olecranon fracture was classified using Mayo classification and the patient was prepared for surgery under general anesthesia. Tension band wiring fixation was performed on the left oblique olecranon fracture and contoured reconstruction plate fixation was performed on the right comminuted fracture. The recovery was uneventful and through intense physiotherapy the elbow function was quite impressive. The patient was able to perform daily living activities on his own having achieved Mayo elbow score (MES) of 90 on the right and 85 on the left.

Background: The aim of this study is to assess the causes and rates of re-operation in olecranon fractures in adults treated with transosseous suture.Methods: We prospectively recruited 29 patients who were treated with this technique between 2010 and 2018. The type of suture used, tourniquet time and surgical time were analyzed for each one. X-rays were taken after 2 weeks, 6 weeks and 6 months, recording complications, causes, rates of re-operation and the final clinical condition.Results: Median time for ischemia and surgery were 51 (95% CI:48;62) and 45 (95% CI:42;55) minutes respectively. The radiologic studies showed diastasis of the posterior cortex in the X-rays taken after 2 weeks and after 6 weeks in 7 (24,1%) cases. Of these cases, two (6,8%) were no longer followed-up after 6 months. There was only one case of aseptic non-union. Among these cases, two patients (6.8%) required surgical debridement due to acute soft tissue infection. No complication had any clinical impact, maintaining all patients full range of motion and no pain. Osteosynthesis removal was not necessary in any case.Conclusion: Transosseous suture with high strength thread is a valid alternative for treating Mayo IIA olecranon fractures in adult patients, decreasing re-operation rates for implant removal. There may be, in a moderate percentage of cases, radiologic diastasis of the posterior cortex at the fracture site, without causing pain nor limiting mobility LEVEL OF EVIDENCE: III.

The wrist is disposed to a variety of instability patterns owing to its complex anatomical and biomechanical properties. Various classification schemes have been proposed to describe the different patterns of carpal instability, of which the Mayo classification is the most commonly used. Understanding the concepts and pertinent terminology of this classification scheme is important for the correct interpretation of images and optimal communication with referring physicians. Standard wrist radiographs are the first line of imaging in carpal instability. Additional information may be obtained with the use of stress radiographs and other imaging modalities.

Hypothesis/Background Olecranon fractures have variable size of the proximal fragment, patterns of fragmentation, and subluxation of the ulnohumeral joint that might be better understood and categorized on the basis of quantitative 3-dimensional computed tomography analysis. Mayo type I fractures are undisplaced, Mayo type II are displaced and stable, and Mayo type III are displaced and unstable. The last is categorized into anterior and posterior dislocations. The purpose of this study was to further clarify fracture morphology between Mayo type I, II, and III fractures. Methods Three-dimensional models were created for a consecutive series of 78 patients with olecranon fractures that were evaluated with computed tomography. We determined the total number of fracture fragments, the volume and articular surface area of each fracture fragment, and the degree of displacement of the most proximal olecranon fracture fragment. Results Displaced olecranon fractures were more comminuted than nondisplaced fractures ( P  = .02). Displaced fractures without ulnohumeral subluxation were smallest in terms of both volume ( P  < .001) and articular surface involvement ( P  < .001) of the most proximal olecranon fracture fragment. There was no difference in average displacement of the proximal fragment between displaced fractures with and without ulnohumeral subluxation ( P  = .74). Anterior olecranon fracture-dislocations created more displaced ( P  = .04) and smaller proximal fragments than posterior fracture-dislocations ( P  = .005), with comparable fragmentation on average ( P  = .60). Discussion/Conclusion The ability to quantify volume, articular surface area, displacement, and fragmentation using quantitative 3-dimensional computed tomography should be considered when increased knowledge of fracture morphology and fracture patterns might be useful.

Background Olecranon fractures are common in elderly patients, causing significant morbidity and functional impairment. Traditional surgical treatments are often complicated by hardware failure and prominence, frequently requiring reoperation. To address these concerns, a suture anchor fixation technique was developed and clinically evaluated. Methods A consecutive series of elderly patients treated with this technique from 2006 to 2013 at a single institution were studied. All cases were surgically repaired with nonmetallic fully threaded suture anchors in a double-row fashion. Clinical outcome measures including the shortened Disabilities of the Arm, Shoulder, and Hand score, the Oxford Elbow Score, and the 12-Item Short Form Health Survey score were obtained. Results Eight female patients with Mayo IIA or IIB fractures were identified. The mean age of the patients at time of operation was 73.5 ± 10.7 years (range, 59.3-88.8 years). The average time from injury to operation was 5.7 ± 3.7 days. The average follow-up was 5.1 ± 2.5 years (range, 0.8-7.4 years). Six patients were available for long-term follow-up; 1 patient had died, and 1 patient was unable to be contacted despite multiple attempts. There were no intraoperative complications or reoperations. All 8 patients healed uneventfully in an acceptable position without displacement. Postoperatively, the average Oxford Elbow Score was 47.17 ± 2.04; the average shortened Disabilities of the Arm, Shoulder, and Hand score was 6.43 ± 9.47; and the average 12-Item Short Form Health Survey scores were 49.02 ± 16.59 and 55.38 ± 4.05 for the physical and mental component scales, respectively. Conclusion Suture anchor fixation of olecranon fractures in the elderly population provides excellent long-term radiographic and clinical outcomes without hardware complications associated with traditional fixation methods.

Background Although classification systems of olecranon fractures are important to help choose the best treatment and to predict prognosis, their degree of observer agreement is poorly investigated. The objective of this study was to investigate the intraobserver and interobserver reliability of currently used classification systems for olecranon fractures. Our hypothesis is that the Colton classification presents an acceptable agreement because it is simpler to use; on the other hand, considering the AO classification's complexity, we expect it to reach a lower level of agreement. Methods Radiographic images of elbow joint fractures were classified according to Colton, AO, Mayo, and Schatzker classification systems. The raters were 8 orthopedic surgeons split into 2 groups with 4 participants each, one with specialists in upper extremity surgery and the other with orthopedic surgeons without a specific focus on upper extremity surgery. This first procedure was the pretest training, aimed at calibrating participants' judgment. Image classification was conducted after all training was completed. After 30 days from the initial rating session, the test was conducted once again following the exact same procedures. Results The Colton classification has substantial intraobserver and interobserver agreement for specialists and nonspecialists. The Schatzker classification revealed a fair agreement for both specialists and nonspecialists. A fair concordance was also found for the Mayo classification. The AO classification demonstrated a moderate rate of agreement for specialists, whereas nonspecialists presented slight intraobserver agreement. Conclusion No classification system is widely accepted because it can be affected by interobserver variability, which can raise questions about its use in a research as well as in a clinical context.

Background: Literature lacks data concerning several epidemiologic aspects of isolated olecranon fractures (IOFs). The few studies that have analyzed this type of fracture show a low sample size and contradicting results., Methods: This retrospective study included 165 consecutive patients (82 men and 83 women) who sustained an IOF in the past 10 years. Participants who were aged <16 years or had a previous elbow fracture or had a fracture that involved other bones of the elbow joint were excluded. Data regarding age, sex, season, date, and fracture side were collected. As per the mechanism of injury, we arbitrarily distinguished 7 subgroups. IOFs were classified as per the Mayo and AO classifications using x-ray. Statistics were performed., Results: The patients' mean age was 58.5 (standard deviation [SD], 21.3) years, and men and women were aged 48.1 (SD, 19.8) years and 67.9 (SD, 18.8) years, respectively. The most frequent fracture patterns were the MAYO 2A and the AO 2U1B1(d). Low-energy mechanisms caused simple dislocated-stable fractures, whereas high-energy mechanisms caused both simple and comminuted displaced-stable fractures. Significant differences in the trauma mechanism were found between male and female patients. The former fractures showed a bimodal distribution depending on the patients' age group, whereas in women, the traumatic event was mainly represented by a low-energy mechanism. Overall, the most common cause of fracture was a low-energy accident. The seasonal distribution of fractures was different for male and female patients being more frequent in summer among young men and more frequent in winter among the elderly, both men and women. The left side was involved in 87 patients., Conclusion: IOFs occur equally in both genders, although with different age distribution. The most common fracture pattern was a simple displaced-stable fracture (MAYO 2A and AO 2U1B1[d]). Young men are more often subject to high-energy injuries that occur in road accidents, whereas with aging, they become more prone to fragility fractures as women. Female patients are usually older and are mostly affected by low-energy traumas as a fall from a standing height., (© 2022 The Authors.)
