Abstract Introduction The coronoid process plays a key-role in preserving elbow stability. Currently, there are no radiographic indexes conceived to assess the intrinsic elbow stability and the joint congruency. The aim of this study is to present new radiological parameters, which will help assess the intrinsic stability of the ulnohumeral joint and to define normal values of these indexes in a normal, healthy population. Methods Four independent observers (two orthopaedic surgeons and two radiologists) selected lateral view X-rays of subjects with no history of upper limb disease or surgery. The following radiographic indexes were defined: trochlear depth index (TDI); anterior coverage index (ACI); posterior coverage index (PCI); olecranon–coronoid angle (OCA); radiographic coverage angle (RCA). Inter-observer and intra-observer reproducibility were assessed for each index. Results 126 subjects were included. Standardized lateral elbow radiographs (62 left and 64 right elbows) were obtained and analysed. The mean TDI was 0.46 ± 0.06 (0.3–1.6), the mean ACI was 2.0 ± 0.2 (1.6–3.1) and the mean PCI was 1.3 ± 0.1 (1.0–1.9). The mean RCA was 179.6 ± 8.3° (normalized RCA: 49.9 ± 2.3%) and the mean OCA was 24.6 ± 3.7°. The indexes had a high-grade of inter-observer and intra-observer reliability for each of the four observers. Significantly higher values were found for males for TDI, ACI, PCI and RCA. Conclusion The novel radiological parameters described are simple, reliable and easily reproducible. These features make them a promising tool for radiographic evaluation both for orthopaedic surgeons and for radiologists in the emergency department setting or during outpatient services. Level of evidence Basic Science Study (Case Series). Clinical relevance The novel radiological parameters described are reliable, easily reproducible and become handy for orthopaedic surgeons as well as radiologists in daily clinical practice.

Abstract: The prevalence of progressive forms of pneumoconiosis in the Russian Federation has been little studied. At the same time, the number of workers exposed to silicon dioxide, both in our country and abroad, is not decreasing. The purpose of our research to determine the criteria for the progression of pneumoconiosis in miners. A retrospective analysis of the results of a comprehensive medical examination of 150 miners of the Rostov region, observed in the center of occupational pathology, was carried out. All patients underwent radiography, computed tomography of the chest organs, and spirometry. X-ray description of the changes was carried out in accordance with the recommendations of the ILO. As a result, 24.5% had statistically significant signs of negative dynamics of functional and radiological indicators, which we referred to the criteria of progression. Thus, the progression of pneumoconiosis is determined by the negative dynamics of clinical and radiological parameters.

For the purpose of tracing the migration of radioactive materials in the environment it is essential to monitor meteorological and radiological parameters by a unified measurement system, because of the strong correlation of meteorological and radiological parameters. The ultimate goal is the prevention of radioactivity-induced diseases and disorders caused by radioactivity in both human population and the environment. A unified meteorological and radiological monitoring system can be readily implemented by using the organization and communication infrastructure of HYPERION technology. This would ensure an automatic and centralized acquisition of all relevant parameters.

Purpose. Compare the clinical and radiological results of treatment of patients with spinal deformities operated on using the PSO method and corrective fusion in the lumbar spine. Materials and methods. Retrospective monocenter cohort study. The data of 42 patients were analyzed. PSO (group I) was performed in 12 patients; 30 patients had a combination of surgical methods (group II) with mandatory ventral corrective spinal fusion at levels L4-L5, L5-S1. Clinical and radiological parameters were evaluated during hospitalization and at least 1 year later. Results. Postoperative hospitalization in group I 32.5 7.4 days, 27.1 7.4 in group II (p = 0.558758). The duration of the operation in group I was 402.5 55.6 minutes, in group II 526.0 116.2 minutes (p = 0.001124); blood loss 1862.5 454.3 ml versus 1096.0 543.3 ml (p = 0.000171). In both groups, significantly improved clinical and radiological parameters after surgery and after 1 year (p 0.05). In group II, as compared with group I after surgery and more than 1 year: lower back pain according to VAS (p = 0.015424 and p = 0.015424); below ODI after 1 year was (p = 0.000001). In group I, compared with group II after surgery and after 1 year, SVA is less (p = 0.029879 and p = 0.000014), lumbar lordosis is higher (p = 0.045002 and p = 0.024120), LDI is restored more optimally (p = 0.000001 and p = 0.000002), the GAP is lower (p = 0.005845 and p = 0.002639). The ideal Russoly type is restored more often in patients of group II (p = 0,00032). Complications in group I were noted in 12 (100%) patients, in group II in 13 (43.3%) patients (p = 0.001). Conclusions. In multistep surgical treatment compared with PSO, the anterior corrective interbody fusion L4-L5, L5-S1 reliably better and more harmoniously restores the sagittal balance parameters, has significantly lower volume of intraoperative blood loss, fewer perioperative complications and significantly improves the quality of life of patients.

Background: Several osteotomies have been described for the correction of acetabular dysplasia associated with variable outcomes. The purpose of our study was to evaluate the effect of Dega transiliac osteotomy in radiological correction of acetabular dysplasia by assessing the change in various radiological parameters from preoperative period to postoperative period and at a follow up of two years.Methods: This was a prospective observational study conducted on 35 patients of either sex, in the age range of 18 months to 8 years, presenting to the paediatric orthopaedic OPD, of Artemis Health Institute, Gurgaon, Haryana, India between January 2012 and September 2014 in whom a diagnosis of acetabular dysplasia was made. All the patients underwent Dega transiliac osteotomy and the effectiveness of this osteotomy in the correction of acetabular dysplasia was assessed by measuring various radiological parameters preoperatively, postoperatively, and at a follow up of two years. The various radiological parameters included acetabular index (AI), centre edge angle of wiberg (CEAW), reimer’s extrusion index (REI) and the shenton’s line (SL).Results: In present study sample of 35 cases, 29 had DDH, 4 were secondary to cerebral palsy and 2 had developed dysplasia following septic arthritis of the hip. The sex distribution showed 19 females and 16 male patients. All the patients underwent Dega transiliac osteotomy at a mean age of 42.94±21.68 months. The mean value of AI improved from 42.43±4.77 degrees in preoperative period to 19.86±2.45 degrees at follow up. The mean value of CEAW improved from - 32.49±21.60 degrees in preoperative period to 32.06±5.48 degrees at follow up. The mean value of REI, improved from 91.06±21.43 % in preoperative period to 0.29±1.18 % at follow up. The SL was broken in all the 35 patients preoperatively, while at follow up it was continuous in all the patients. These changes in all the four parameters were statistically highly significant (p value<0.001).Conclusions: Thus results of present study demonstrate that Dega osteotomy is a safe, effective and versatile surgical procedure for the treatment of acetabular dysplasia secondary to DDH and other disorders. Since the majority of the patients included in this study had the diagnosis of DDH, the results of this study are more representative of dysplasia associated with DDH.

New Guidelines

Abstract Background Fractures of the distal radius are a common injury. The British Orthopaedic Association (BOA) and The British Society for Surgery of the Hand (BSSH) have released new guidelines outlining the management of these fractures, specifically identifying “thresholds for intervention,” based on radiological parameters for management with open reduction and internal fixation (ORIF). Questions/Purposes Have our distal radius fractures (DRFs), previously managed with ORIF, met the new guidelines' thresholds for intervention, based on radiological parameters? Patients and Methods A retrospective assessment of DRFs treated with ORIF was performed between January 2017 and August 2018. Patients were categorized into three cohorts based on their age. The five radiological parameters of ulnar variance, dorsal tilt, radial inclination, radial height, and intra-articular step were measured on the initial plain radiograph, “pre-manipulation film,” postplaster application radiograph, and “post-manipulation film.”These were compared with the “thresholds for intervention” outlined in the BOA/BSSH guidelines. Results A total of 94 patients underwent an ORIF with a mean age of 56 years (range 17–86 years). As many as 75.74% of patients on the ”pre-manipulation film” met the “threshold for intervention” on at least one radiological parameter, while 53.57% of patients on the “post-manipulation” met at least one “threshold for intervention.” Dorsal tilt was the parameter that most often met the threshold in both films at 53.37% and 40.11%, respectively. Conclusion Within our trust, there is a tendency to over manage the distal radius fracture with ORIF, potentially resulting in unnecessary operations. Education surrounding the new guidelines will better serve our decision-making. Level of Evidence This is a level III study.

Recurrent Patellar Instability

Background: No clear guidelines or widespread consensus has defined a threshold value of tibial tuberosity–trochlear groove (TT-TG) distance for choosing the appropriate surgical procedures when additional tibial tuberosity osteotomy (TTO) should be added to augment medial patellofemoral ligament (MPFL) reconstruction for recurrent patellar instability. Purpose: To compare the clinical outcomes between MPFL reconstruction and MPFL reconstruction with TTO for patients who have patellar instability with a TT-TG distance of 15 to 25 mm. Study Design: Cohort study; Level of evidence, 3. Methods: We retrospectively analyzed 81 patients who underwent surgical treatment using either MPFL reconstruction or MPFL reconstruction with TTO for recurrent patellar instability with a TT-TG distance of 15 to 25 mm; the mean follow-up was 25.2 months (range, 12.0-53.0 months). The patients were divided into 2 groups: isolated MPFL reconstruction (iMPFL group; n = 36) performed by 2 surgeons and MPFL reconstruction with TTO (TTO group; n = 45) performed by another 2 surgeons. Clinical outcomes were assessed using the Kujala score, Knee injury and Osteoarthritis Outcome Score, and Tegner activity score. Radiological parameters, including patellar height, TT-TG distance, patellar tilt, and congruence angle were compared between the 2 groups. Functional failure based on clinical apprehension sign, repeat subluxation or dislocation, and subjective instability and complications was assessed at the final follow-up. We also compared clinical outcomes based on subgroups of preoperative TT-TG distance (15 mm ≤ TT-TG ≤ 20 mm vs 20 mm < TT-TG ≤ 25 mm). Results: All of the clinical outcome parameters significantly improved in both groups at the final follow-up ( P < .001), with no significant differences between groups. The radiological parameters also showed no significant differences between the 2 groups. The incidence of functional failure was similar between the 2 groups (3 failures in the TTO group and 2 failures in the iMPFL group; P = .42). In the TTO group, 1 patient experienced a repeat dislocation postoperatively and 2 patients had subjective instability; in the iMPFL group, 2 patients had subjective instability. The prevalence of complications did not differ between the 2 groups ( P = .410). In the subgroup analysis based on TT-TG distance, we did not note any differences in clinical outcomes between iMPFL and TTO groups in subgroups of 15 mm ≤ TT-TG ≤ 20 mm and 20 mm < TT-TG ≤ 25 mm. Conclusion: MPFL reconstruction with and without TTO provided similar, satisfactory clinical outcomes and low redislocation rates for patients who had patellar instability with a TT-TG distance of 15 to 25 mm, without statistical difference. Thus, our findings suggest that iMPFL reconstruction is a safe and reliable treatment for patients with recurrent patellar dislocation with a TT-TG distance of 15 to 25 mm, without the disadvantages derived from TTO.
