This study aims to compare the ultrasound size of the ulnar nerve between CuTS patients and control subjects, to find the cut off size for diagnosis, and to validate the use of USG as an adjunct in CuTS diagnosis. Materials and Methods: There were 23 elbows with clinical and nerve conduction test (NCT) confirmed CuTS, and 42 elbows in the control group. Cases with elbow deformities, old ulnar nerve injuries and postoperative cases were excluded. The ulnar nerve cross sectional area (CSA) was measured at 6 different levels and positions: over the medial epicondyle (ME) in elbow flexion/extension, 2 cm and 5 cm distal to the ME, 2 cm and 5 cm proximal to the ME. A cut off CSA value for CuTS diagnosis was derived. Correlation between ulnar nerve CSAs and NCT was analysed. Results: The age and gender distribution were similar in both groups (61.2 vs 56.6; M > F, p > 0.05). The mean CSA of the CuTS group vs control group was 19.2 mm2 vs 7.0 mm2, 19.5 mm2 vs 7.1 mm2, 20.8 mm2 vs 8.1 mm2 at ME flexion, ME extension and maximal CSA respectively. The derived CSA cut off value for CuTS at ME flexion, ME extension and maximal CSA were 10.5 mm2, 11.5 mm2, and 15 mm2 respectively. The CSA difference at different levels between the 2 groups were significant except at 5 cm proximal to ME. A strong negative correlation was seen between the CSA and the across elbow nerve conduction velocity, with correlation coefficient of −0.748 at ME flexion, −0.654 at ME extension and –0.676 at maximal CSA. Conclusion: USG can be used as an adjunct for the diagnosis of CuTS with high accuracy and patient safety. It can also be used to delineate possible anatomical etiologies at the cubital tunnel.","PeriodicalId":42408,"journal":{"name":"Journal of Orthopaedics Trauma and Rehabilitation","volume":"24 15","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135113268","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods The study included ten patients with symptomatic postoperative radial neck nonunion from 2010 to 2016 which were treated surgically with either bone grafting (bone-grafting group) or radial head resection (resection group). The patient demographics, pre- and postoperative clinical scores were recorded. The PubMed, OVID/Medline, Cochrane, Google Scholar, and EMBASE databases were searched using the keywords “radial neck nonunion” according to the MeSH index. A systematic review was performed using PRISMA guidelines. Results Average time from primary surgery to nonunion was 10.7 months. Four and six patients received bone-grafting and radial head resection procedure. The mean age for resection group is older than bone grafting group (59 versus 28.75 years). The resection group patients presented with more significant pre-operative symptoms, associated injuries, loss of radial head articular congruity, and bone loss. All patients achieved favorable outcome. The systematic review included 12 publications with a total of 19 patients. The incidence of radial neck nonunion was 73.7% and 26.3% following conservative and operative treatment respectively. About 42.1% received operative treatment due to symptomatic progression. Conclusions Radial neck nonunion is rare and mostly appears asymptomatic. Operative treatment is advocated for symptomatic cases. Articular congruity and degree of bone loss are major determinant for surgical treatment of radial neck nonunion. Surgical treatment for symptomatic radial neck nonunion resulted in favorable outcome.","PeriodicalId":42408,"journal":{"name":"Journal of Orthopaedics Trauma and Rehabilitation","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134958258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patient-centered care needs to encompass all aspects of this treatment. Limited research is available on outpatient satisfaction and patient-reported outcomes from fracture clinic (FRCL). The purpose of this evaluation is to report on pain levels perceived by patients from minor orthopaedic procedures that were necessary for the continued management of fracture care. Methods Patients were recruited in the FRCL if they were planned to undergo minor orthopaedic procedures. They were asked to report the pain they experienced at baseline, during the procedure, 20 min post-procedure, and 24 h following the procedure on a verbal numeric rating scale of 0–10. Healthcare professionals (HCP) were then asked to rank their perception of the severity of pain from each procedure type. Finally, qualitative interviews were conducted on a convenience sample of patients. Results 51 patients were included in this evaluation. Halo pin, external fixation device, Kirschner wire, and screw removal exhibited a mean increase in pain from baseline greater than 3 units during the procedure. The external fixation device removal group showed the greatest pain reported with a statistically significant increase from baseline to the end of the procedure (mean = 7.1; p = 0.002). There was good concordance of pain perception by the HCP to patient experience. Qualitative interviewing revealed two major themes.

This study aimed to quantify the change in sports medicine operations and its distributions during the COVID-19 pandemic, which could be useful for healthcare providers and policymakers plan in terms of resource planning in case of another severe infection outbreak in the future. Methods: Data, including age and gender of the patients and the types of operation, of all the surgeries performed by the Division of Sports and Arthroscopic Surgery in our institution from September 2017 to June 2022 was retrieved. The first 29 months of the 58 months period were classified as pre-COVID-19. Result: During the COVID-19 pandemic, there was a 20.9% reduction in the total number of sports and arthroscopic surgeries performed, from 10.1 to 8.0 per month ( p = 0.042). The number of shoulder operations was significantly reduced by 32% ( p = 0.029), with rotator cuff surgery reduced by 42% ( p = 0.022). The number of knee operations decreased by 15% ( p = 0.278), with anterior cruciate ligament (ACL) surgery reduced by 20% ( p = 0.093). Notably, the relative proportion of knee and shoulder operations, as well as the patient demographics, remained similar during the COVID-19 pandemic. Conclusion: The reduction in the number of ACL and rotator cuff surgeries could be related to the reduced sports activity and manual labour activity during the lockdown periods of the pandemic. This study provides information and insight into the demand for sports medicine-related operations during the pandemic. It may be practical to limit elective operation sessions for sports and arthroscopic surgery during the pandemic, especially when resources are scarce. However, it is essential to strike a good balance between providing necessary care for patients who require these surgeries, while also taking appropriate measures to combat the pandemic.","PeriodicalId":42408,"journal":{"name":"Journal of Orthopaedics Trauma and Rehabilitation","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135926482","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, complications associated with metallic implants causing soft tissue irritation are not infrequent. Since 1998, there have been emerging case reports and series reporting the use of non-metallic implants, such as braided sutures, in the fixation of patella fractures 3. However, there is a limited clinical study on a direct comparison between metal and suture fixation in patella fractures. The aim of this study is to evaluate the outcome of all-suture fixation in patella fractures and to compare all-suture and metal fixation in mid-pole fractures. A total number of 50 patients with operated fracture patella were retrospectively reviewed in a 2.5-year period. Primary outcomes included operation time, time for fracture union and postoperative knee function. Secondary outcomes include complications, need for secondary operations due to prominent implants, infection or loss of fixation. There was no statistically significant difference concerning time for fracture union, operation time and postoperative functional knee score between the three fixation methods. The rate of secondary operations was higher in the hybrid group (7 out of 11, 63.6%) and metal group (7 out of 13, 53.8%), and was lowest in an all-suture group (0 out of 28, 0%). Metal implant breakage and soft tissue irritation were the main reasons for secondary operations, which was significantly lower in the all-suture group ( p < 0.0003). Subgroup analysis for mid-pole patella fractures showed similar results in which all primary outcomes showed no statistically significant difference, while the need for secondary operations was higher in the metal group ( p < 0.003). All-suture fixation for patella fractures is a feasible option not limited to distal pole fractures. In our series, this technique achieved similar outcomes when compared with traditional metal implants, with lower rates of secondary operations, and could be safely employed in mid-pole fractures as well.","PeriodicalId":42408,"journal":{"name":"Journal of Orthopaedics Trauma and Rehabilitation","volume":"24 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2023-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87678879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The braces used for idiopathic scoliosis can be divided into soft and rigid braces. SpineCor brace is mostly recommended for subjects who refused to use rigid braces. However, it is not well understood whether soft braces are as effective as rigid braces to control scoliosis curve progression or not. Therefore, this study aimed to evaluate the effectiveness of soft braces used for idiopathic scoliotic curves compared to other available braces. Method: A search was done in databases including PubMed, Google Scholar, ISI Web of Knowledge, Ebsco, Embasco, and Scopus. Keywords of the soft brace, SpineCor were used in combination with scoliosis. The quality of the selected studies was evaluated by use of the Down and Black tool, which is a reliable method to evaluate the quality of the studies. Results: Based on the aforementioned keywords, 52 studies were achieved. After reviewing the title and abstract of each study 11 papers were selected for final analysis. Eight studies were on the evaluation of the effectiveness of the SpineCor brace on scoliosis. There were three studies on the comparison of the SpineCor with other available rigid braces. Conclusion: The results of selected studies confirmed that the SpineCor brace can be used to control the progression of idiopathic scoliosis. However, its effectiveness is limited to the curves with a severity of fewer than 30° and for the patients with Risser signs 0–3. The effectiveness of SpineCor is not comparable with a rigid brace, especially for the curve above 40°. SpineCor stabilizes the spine with high compliance and with significant improvement in posture, rib hump, lumbar predominance, and muscle contraction.","PeriodicalId":42408,"journal":{"name":"Journal of Orthopaedics Trauma and Rehabilitation","volume":"55 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2023-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84874431","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 123 (37 conventional and 86 KA2) cases of elective primary TKA were reviewed. Hip-knee-ankle (HKA) angle, mechanical lateral distal femoral angle (mLDFA), and anatomical lateral distal femoral angle (aLDFA) were measured from hip-to-ankle EOS radiographs. Accuracy of conventional alignment and KA2 navigation system was assessed by measuring the difference between intraoperative goal and postoperative radiographic measurements of the components for each respective case. There was no significant difference between conventional alignment methods and KA2 navigation in achieving a neutral mechanical alignment of the lower limb. KA2 navigation was significantly more accurate than conventional alignment methods for optimal positioning of the tibial component in both the coronal and sagittal plane, while no significant difference between the two groups was appreciated in the positioning of the femoral component in the coronal plane. TKA using the accelerometer-based KA2 system was found to offer a high degree of accuracy in component alignment, and in particular, significantly improved tibial component alignment in comparison with conventional alignment methods in a Chinese population.
