Since various medications can control the rate of fractures and subsequent complications of osteoporosis, the early detection of the disease is crucial. This systematic study aimed to compare the diagnostic accuracy of Singh index (SI) with dual-energy X-ray absorptiometry (DEXA) as a benchmark standard for diagnosing osteoporosis.

The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) were utilized in the current study. A detailed search was carried out using PubMed and Scopus from inception to 30 May 2022. Examining quality of the studies was performed by the Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2).

A total of 22 studies were included. In general, 50% of the studies considered SI a poor screening tool for detecting osteoporosis due to a negligible inter-observer agreement between SI and DEXA or a poor correlation of SI with the bone mineral density (BMD) category or DEXA T-score. A moderate inter-observer agreement was reported for SI in 5 (55.6%) studies. Among the studies assessing the sensitivity and specificity of SI compared to DEXA (n=13), six studies estimated a low sensitivity for SI.

While there is supporting evidence indicating the potential usefulness of SI for predicting femoral neck fractures in individuals with suspected osteoporosis, numerous studies challenge its reliability and diagnostic value as a screening tool for identifying femoral neck osteoporosis. Further primary studies are required to verify the effectiveness of the SI index in identifying populations at risk of osteoporosis. Level of evidence: V

Arthroscopic Latarjet for glenohumeral stabilization has emerged as an alternative to the open approach; however, the evidence to date has questioned if this technique delivers improved outcomes. This analysis provides an assessment of the cost and utility associated with arthroscopic versus open Latarjet. The cost-effectiveness of Latarjet stabilization was modeled over a ten-year period. Institutional cases were reviewed for equipment utilization. Cost data from ambulatory surgical centers was obtained for each piece of equipment used intraoperatively. Based upon prior analyses, the operating room cost was assigned a value of $36.14 per minute. To determine effectiveness, a utility score was derived based upon prior analysis of shoulder stabilization using the EuroQol (EQ) 5D. For reoperations, a utility score of 0.01 was assigned for a single year for revision surgeries for instability and 0.5 for minor procedures. Probability of surgical outcomes and operative time for arthroscopic and open Latarjet were taken from prior studies comparing outcomes of these procedures. Decisiontree analysis utilizing these values was performed. Based upon equipment and operating room costs, arthroscopic Latarjet was found to cost $2,796.87 more than the equivalent open procedure. Analysis of the utility of these procedures were 1.330 and 1.338 quality adjusted life years obtained over the modeled period for arthroscopic versus open Latarjet, respectively. For arthroscopic Latarjet to be cost-equivalent to open Latarjet, surgical time would need to be reduced to 41.5 minutes or the surgical equipment would need to be provided at no expense, while maintaining the same success rates. With nearly identical utility scores favoring open surgery, the added cost associated with arthroscopic Latarjet cannot be supported with available cost and utility data. To provide value, additional benefits such as decreased post-operative narcotic utilization, decreased blood loss, or lower complications of the arthroscopic approach must be demonstrated. Level of evidence: IV

Compare, retrospectively, the medium- and long-term of return to sport rates and re-injury of the anterior cruciate ligament (ACL) in patients submitted to single -bundle (SB) compared to doublebundle (DB) technique reconstruction. Athletes operated by SB or DB ACL reconstruction, with at least five years of follow-up at a single center, were included. The following data were collected: demographic data; competitive sports practice before the injury; previous surgery; injury/surgery to the contralateral knee; return to sports and level of the return; re-injury (time of the re-injury after the first surgery; mechanism of trauma for the re-injury; necessity of operative treatment); signs and complaints related to the knee the last clinical consultation. Seventy-six athletes (27 SB and 49 DB) were included. The return to sport rate (98%) was the same for both groups, and the return to the previous level rate showed an improvement in the DB group but without statistical significance (63% vs. 79%; P = 0.173). However, other outcomes showed higher results for the DB group: lower reinjury rate throughout the follow-up period (41% vs. 18%; P = 0.034) and during the first year of follow-up (22% vs. 4%; P = 0.021), and less stiffness (0% vs. 22%, P = 0.001). While in primary reconstruction cases, there was not a higher re-injury rate using SB (P = 0.744), in the revision cases, SB was correlated with more re-injuries than DB (P = 0.002). The overall re-injury in the medium- and long-term and the return to practice sports at the same level as before surgery in athletes submitted to DB reconstruction were slightly better than those submitted to SB reconstruction, especially in the cases that were asecond time lesion ( revisioned knees). Level of evidence: II

The available evidence on the efficiency of well-known Schroth's exercises (SE) for correcting adolescent idiopathic scoliosis (AIS) is limited, especially in combination with the asymmetric spinal stabilization exercises (ASSE) method. Therefore, we hypothesized that, first, there is no difference in the efficiency of the combined exercises (SE+ASSE) and SE alone in improving Cobb angle, angle of trunk rotation (ATR), and quality of life (QoL) in AIS. Second, there is no difference in the efficiency of SE and no intervention on corresponding variables in treating AIS. This randomized controlled trial (RCT) consisted of 40 patients with mild AIS (10-18-year-old boys) divided into three groups: SE (n=15), SE+ASSE (n=15), and a waitlist control group (n=10). For 12 weeks (three days a week), both experimental groups performed SE, the combined group additionally received ASSE, and the control group received no intervention. The assessment included Cobb angle (photogrammetry), ATR (Adam’s test), and QoL (Scoliosis Research Society-22 questionnaire). It was found that Cobb angle, ATR, and QoL improved significantly in the combined SE+ASSE group (Cobb=16.45° to 9.01°; ATR=4.93° to 1.33°) compared to the SE group (P<.001). In addition, the SE group showed significant amelioration in the mentioned variables (Cobb=15.09° to 9.77°; ATR=4.23° to 2.17°) compared to the control group (P<.001), whereas the control group remained almost unchanged. Based on the obtained results, the combination of SE and ASSE provided more benefits than SE alone, and the SE results were efficient compared to the no-intervention group regarding the correction of scoliosis and related problems. However, patients with moderate to severe scoliosis should also be investigated in longer treatment periods in future. Level of evidence: I

While cervical proprioception deficit has been suggested as a contributing factor to clinical consequences of chronic non-specific neck pain (CNSNP), the effect of addressing such impairments on postural control strategies has remained unexplored. The aim of this study was to compare the response of the postural control system to alteration of sensory afferents in CNSNP with asymptomatic individuals. Furthermore, we examined whether proprioceptive training would yield superior outcomes to routine physiotherapy for improvement of postural control, pain and disabi lity. Center of pressure (CoP) variables of sixty CNSNP patients equally distributed in any of the proprioception-specific or conventional physiotherapy groups and 30 asymptomatic participants were evaluated under four standing conditions:1) normal, 2) foam, 3) cervical extension/eyes open and 4) cervical extension/eyes closed standing. CoP anteroposterior range and anteroposterior and mediolateral velocity in patients were significantly higher than the control group under condition 2 (P<0.05). Patients also demonstrated lower anteroposterior lyapunov exponent under conditions 2 and 4 (P<0.05). Both interventions significantly decreased anteroposterior range and anteroposterior velocity(P<0.05). Anteroposterior lyapunov exponent also increased under condition 2 (P<0.05).. After the interventions, CoP anteroposterior range and anteroposterior velocity were significantly lower in the proprioceptive exercise group than the conventional physiotherapy group (P<0.05). Anteroposterior lyapunov exponent was also significantly higher in the proprioceptive exercise group (P<0.05).This while there was no significant difference between these patients and control group participants in any of the CoP variables after intervention. Our results rejected the hypothesis that impaired neck proprioception in the presence of CNSNP is compensated by overweighting other sources of sensory afferent information. The findings also revealed that while proprioceptive exercises successfully returned postural strategies of CNSNP patients to those in asymptomatic participants, they do not add to clinical recovery of these patients. Level of evidence: I

Majority of Lisfranc fracture-dislocations require anatomic reduction and rigid internal fixation to prevent debilitating sequelae. Current methods include solid screws and flexible fixations which have been in use for many years. Biointegrative screw is a newer option that has not yet been thoroughly investigated for its effectiveness for Lisfranc injuries. The ligaments of the Lisfranc complex were resected in eight lower-leg cadaveric specimens. This was done by eight foot and ankle surgeons individually. Distraction forces were applied from opposite sides at the joint to replicate weight bearing conditions. Three methods of fixation – flexible fixation, metal, and biointegrative screws- were evaluated. The diastasis and area at the level of the ligament were measured at four conditions (replicated injury and each type of fixation) in neutral and distraction conditions using fluoroscopy images. The Wilcoxon test and Kruskal Wallis test were used for comparison. P value <0.05 was considered statistically significant. The diastasis values for the transected ligament scenario were greater than those after all three fixation methods (without distraction) and for metal screw and biointegrative screws (with distraction) (p<0.001). The area at the level of the ligament showed higher values for transected ligament than the three fixatives (p<0.05). Metal screws, flexible fixation and bio-integrative screws showed comparable effectiveness intra-op in the successful correction of Lisfranc injury.

The present study aimed to investigate the responsiveness of the Persian version of the Oswestry Disability Index (ODI), Roland-Morris Disability Questionnaire (RMDQ), and Quebec Back Pain Disability Scale (QBPDS) and detect minimal clinically important changes (MCICs) of these questionnaires in people with lumbar disc herniation. Ninety-two patients with lumbar herniated disc completed the Persianversion of the ODI, RMDQ, and QBPDS before and after the physiotherapy intervention. Additionally, they completed a global rating of change scale after the final physiotherapy session to give an account of non-improved and improved outcomes. The responsiveness of these three disability questionnaires was represented by Receiver Operating Characteristic (ROC) and correlation analyses. The MCIC was defined as the best cut-off when sensitivity and specificity were optimally balanced. Area under the ROC curves are in the acceptable range for ODI and QBPDS (0.78 and 0.70, respectively). Moreover, ODI, RMDQ, and QBPDS have significant positive fair to moderate correlation with the external anchor (P<0.001). The MCIC values for ODI, RMDQ, and QBPDS were 13, 5.5, and 14.5 points, respectively. Our results revealed that the ODI and QBPDS questionnaires have adequate responsiveness to detect improvements in the functional status of lumbar herniated disc patients following a physiotherapy treatment. Therefore, the ODI and QBPDS seem to be superior to the RMDQ for use in randomized clinical trials and clinical settings in patients with herniated lumbar discs. The MCIC scores of 13 and 14.5 obtained for the ODI and QBPDS can help to identify important changes in the clinical status of an individual patient and treatment efficacy. Level of evidence: IV

A 19-year-old male competitive figure skater presented to clinic with a 3 -year history of right ankle swelling. Exam demonstrated a ~6cm diameter mass over the medial malleolus. MRI revealed a well -circumscribed fluid-filled mass. After failing conservative management, the patient underwent surgical excision. Anatomic pathology revealed a pseudocyst with pseudosynovial metaplasia, consistent with malleolar bursitis. Competitive figure skaters can develop significant medial malleolar bursitis due to excessive shear forces from ill-fitting skates. If non-operative management is ineffective, patients can be managed successfully with surgical excision. The patient made a full recovery and has returned to competitive skating without recurrence.  Level of evidence: IV

The interosseous part of the distal tibia is one of the regions in which osteochondroma can occur. Osteochondroma typically occurs among growing children and causes gradual ankle deformity by its pressure effect on the fibula. We presented six patients (Fi ve boys and one girl with median age of 13 years old) with distal tibial interosseous osteochondroma. They were treated by a 18 0̊ fibular osteotomy around its longitudinal axis just proximal and distal to the lesion. All patients were treated without any complication except for one who developed non-union of the site of the fibular osteotomy. In the last follow-up, all the patients were pain-free, and no recurrence was reported. Various methods have been described for resecting interosseous osteochondroma of the distal tibia, with or without fibular osteotomy and with or without acute correction of ankle deformity during resection surgery. Still, there is no consensus over the best method for resecting such lesions. Level of evidence: VI

The global ranking of Iran was at 18 in 2022, with 648 annual publications in Orthopaedics and Sports Medicine, and the global publication share of 1.24 percent.

Missed fractures are a frequent source of malpractice claims in China. We reviewed 52 legal judgments (2021-2023) involving missed fractures to characterize the epidemiology, injury patterns, and diagnostic errors. Most patients were middle-aged males injured in traffic accidents. Lower extremity fractures accounted for over half of missed diagnoses, especially femoral neck (35.4%) and ankle/foot (16.7%). 85.4% were non-displaced fractures, often originally diagnosed in emergency departments. Physicians were found negligent in 63.5% of cases. Occult fractures are prone to underdiagnosis as soft tissue injuries. To reduce errors, physicians should thoroughly evaluate injury mechanisms, perform appropriate radiologic studies, immobilize when uncertain, and ensure follow-up. Quality improvement initiatives are needed to enhance fracture detection. Findings highlight the need for heightened suspicion and diligent radiographic assessment to avoid delayed or missed fracture diagnoses.
