Shoulder MRI parameters in anticipating anterior shoulder dislocation: Are they a reliable and reproducible tool in clinical practice?

BACKGROUND: Anterior shoulder dislocation (ASD) is a frequently observed musculoskeletal injury that is often encountered in the context of sports activities or as a result of trauma. Several magnetic resonance imaging (MRI) parameters have been previously investigated for the purpose of characterizing the anatomical features, which could potentially be responsible for the episodes of instability. These measurements have the potential to identify patients who are susceptible to dislocation. Consequently, ensuring the reliability and consistency of these measurements is crucial in the diagnosis and the management of athletic or traumatic shoulder injuries. METHODS: A group of four students, who had no previous experience in reading MRI series, were selected to perform radiographic measurements on specific parameters of MRI scans. These parameters were glenoid version, glenoid depth, glenoid width, humeral head diameter, humeral containing angle, and the ratio of humeral head diameter to glenoid diameter. The four participants conducted two distinct readings on a total of 28 sets of shoulder MRI scans. Simultaneously, the aforementioned measures were assessed by a consultant shoulder surgeon. RESULTS: A total of 1512 measurements were categorized into nine sets: eight from students' measurements (two per student) and one from the consultant. Intra-rater reliability assessed by the intra-class correlation (ICC) test indicated excellent or good reliability for all parameters (p < 0.05), with glenoid depth showing the highest (0.925) and humeral-containing angles the lowest (0.675) ICC value. Inter-rater correlation, also evaluated using ICC, demonstrated strong correlation (p < 0.05), with glenoid diameter having the highest ICC score (0.935) and glenoid depth the lowest (0.849). Agreement analysis, expressed by Cohen's Kappa test, revealed substantial agreement (p < 0.05) for all parameters, with humeral head diameter having the highest agreement (0.90) and humeral-containing angle the lowest (0.73). CONCLUSION: In this study, intra- and inter-rater MRI parameters are substantially concordant. Credibility comes from these reliability and agreement analyses' statistical significance. Glenoid diameter and depth are the most reliable intrarater and interrater, respectively. Best agreement was with the humeral-containing angle. These data demonstrate repeatability and clinical relevance. LEVEL OF EVIDENCE: Level IV.

Scaphoid nonunion: a novel modification of Matti-Russe technique with enhanced recovery and full clinical and radiographic union.

BACKGROUND: A scaphoid fracture is a common injury affecting the wrist joint. A fracture of the carpus scaphoid can heal uneventfully or be complicated by non-union. Scaphoid non-union can result in persistent wrist pain, and with functional difficulties affecting all activities of daily living of the patients, this disability is expected to be significant since most of these patients are young active adults. HYPOTHESIS: Extensive removal of the bone from the scaphoid, with the application of a large amount of cancellous bone graft and fixation with two to three wires, could lead to a high union rate and a good functional outcome. METHODS: Eighteen patients with scaphoid fracture non-union were recruited during their visit to the upper limb clinic at our institute. Demographic data were collected, and data regarding comorbidities, smoking, manual work, and others were recorded. Data regarding the interval between injury and surgery, time to radiographic union, and functional wrist scores were reported as well. RESULTS: A cohort of 18 patients was included. The mean age of patients was 30 years; most of our patients were healthy (83.3%), and more than two-thirds were smokers (72.2%). The mean follow-up time was 18 months (1.5 years), 15 patients (83.3%) achieved radiographic unions by 2-3 months, and the remaining 3 patients (16.7%) achieved radiographic unions by (4-5) months, i.e., all patients achieved successful radiographic unions by 5 months at maximum. The mean Mayo score for our series was 83.6 (± 12.4), with 5 patients (27%) achieved ≥ 95% which indicates a significantly high functioning wrist in our cohort. CONCLUSION: Our modified technique with enhanced stability from using three k-wires can achieve full clinical and radiographic unions and result in enhanced recovery postoperatively with cast immobilization limited to 6 weeks total. LEVEL OF EVIDENCE: IV Case series study.

Talar neck non-union in an athlete successfully treated with a synthetic bone graft: A case report.

Talar neck non-union is a rare complication of talar neck fractures. No guidelines are currently available for the proper management of this complication; thus, it can be hard for orthopaedic surgeons to successfully treat. Here we are reporting a case of talar neck non-union occurring in a 22-year-old male patient after a road traffic accident and presented to our institution 10 months after the initial injury. The non-union was managed surgically with an open reduction and internal fixation with the use of a synthetic bone graft to fill the defects. The patient regained full function and remained without complications after 7 years of follow up.

A novel method in assessing lower limb motor function.

PURPOSE: To propose a novel, accurate, and easy to perform test replacing the manual muscle testing. Our target is to develop a valuable tool for identification of patients with neurological motor impairment precisely, rapidly, and easily. METHODS: We have randomly selected patients presenting to the clinic complaining of back pain with or without lower limb symptoms. These patients were asked to walk on their heels and on their toes. Being unable to walk on heels and/or toes, the patient is considered to have positive test result (abnormal finding). After that, a full and thorough neurological examination was performed on every patient by an orthopedic resident doctor. We looked specifically to the correlation between the ability to do toe-heel walking with the results of the detailed neurological examination. RESULTS: Toe-heel walking test was able to detect all patients with weakness in their lower limb musculature. The results from the current investigation indicate a very high Pearson correlation of 0.95 ( p = 0.001) between the toe-heel test and manual muscle testing. CONCLUSION: Toe-heel walking test is superior to detailed neurological examination in identification of patients with weakness, sphincter problem, and/or positive straight leg raising test. This test is both simple and rapidly performed test, which can be easily done by any health-care provider. Owing to its ease, this test is not restricted to medical doctors, but it could be accurately performed by any health-care provider such as nurses and physiotherapists. This will enable us to decrease the referral to the specialty clinic and to decrease the overall cost.

Does integrating research into the prosthetics and orthotics undergraduate curriculum enhance students' clinical practice? An interview study on students' perception.

BACKGROUND: Problem-based learning (where rather than feeding students the knowledge, they look for it themselves) has long been thought of as an ideal approach in teaching because it would encourage students to acquire knowledge from an undetermined medium of wrong and right answers. However, the effect of such approach in the learning experience of prosthetics and orthotics students has never been investigated. OBJECTIVES: This study explores the implications of integrating problem-based learning into teaching on the students' learning experience via implementing a research-informed clinical practice module into the curriculum of last year prosthetics and orthotics undergraduate students at the University of Jordan (Amman, Jordan). STUDY DESIGN: Qualitative research pilot study. METHODS: Grounded theory approach was used based on the data collected from interviewing a focus group of four students. RESULTS: Students have identified a number of arguments from their experience in the research-informed clinical practice where, generally speaking, students described research-informed clinical practice as a very good method of education. CONCLUSION: Integrating problem-based learning into teaching has many positive implications. In particular, students pointed out that their learning experience and clinical practice have much improved after the research-informed clinical practice. CLINICAL RELEVANCE: Findings from this investigation demonstrate that embedding problem-based learning into prosthetics and orthotics students' curriculum has the potential to enhance students' learning experience, particularly students' evidence-based practice. This may lead to graduates who are more knowledgeable and thus who can offer the optimal patient care (i.e. clinical practice).

A systematic procedure to optimise dose and image quality for the measurement of inter-vertebral angles from lateral spinal projections using Cobb and superimposition methods.

BACKGROUND: Patients with vertebral column deformations are exposed to high risks associated with ionising radiation exposure. Risks are further increased due to the serial X-ray images that are needed to measure and asses their spinal deformation using Cobb or superimposition methods. Therefore, optimising such X-ray practice, via reducing dose whilst maintaining image quality, is a necessity. OBJECTIVES: With a specific focus on lateral thoraco-lumbar images for Cobb and superimposition measurements, this paper outlines a systematic procedure to the optimisation of X-ray practice. METHODS: Optimisation was conducted based on suitable image quality from minimal dose. Image quality was appraised using a visual-analogue-rating-scale, and Monte-Carlo modelling was used for dose estimation. The optimised X-ray practice was identified by imaging healthy normal-weight male adult living human volunteers. RESULTS: The optimised practice consisted of: anode towards the head, broad focus, no OID or grid, 80 kVp, 32 mAs and 130 cm SID. CONCLUSION: Images of suitable quality for laterally assessing spinal conditions using Cobb or superimposition measurements were produced from an effective dose of 0.05 mSv, which is 83% less than the average effective dose used in the UK for lateral thoracic/lumbar exposures. This optimisation procedure can be adopted and use for optimisation of other radiographic techniques.
