Lisfranc Injury Diagnosis: What Is the Diagnostic Reliability of New Radiographic Signs Using Three-dimensional CT?

BACKGROUND: Up to one-third of Lisfranc injuries (an injury affecting the normal stability, alignment, and congruency of the tarsometatarsal joints) are misdiagnosed. Delayed diagnosis and improper treatment may lead to long-term, irreversible sequela and functional disability. Recently, the employment of three-dimensional (3D) CT demonstrated higher diagnostic reliability, but there is limited evidence on this, and radiologic features of Lisfranc injuries when using this diagnostic modality are not well described. QUESTION/PURPOSE: What is the diagnostic performance of several novel radiographic signs on 3D CT when evaluating for Lisfranc injury, namely the Mercedes sign, the peeking metatarsal sign, and the peeking cuneiform sign, and what is the interobserver and intraobserver reliability of those diagnostic signs? METHODS: In this retrospective, diagnostic study, video clips of 3D CT reconstructions of 52 feet with intraoperatively confirmed Lisfranc injuries and 50 asymptomatic feet with a normal appearance of the tarsometatarsal joints, as ascertained by a subspecialty-trained foot and ankle surgeon and a musculoskeletal radiologist, were analyzed by two foot and ankle specialists and three orthopaedic residents twice each, with a washout period of 2 weeks. Among the 52 patients with intraoperative evidence of Lisfranc injury, there were 27 male patients and 25 female patients, with a median (IQR) age of 40 years (23 to 58); among the 50 controls, there were 36 male and 14 female patients, with a median age of 38 years (IQR 33 to 49). For each video clip, the presence of all three radiographic signs was documented (each sign was rated in a binary yes/no fashion). Before the evaluations, all observers underwent a short training session by the head of the foot and ankle department. Later, these reading were used to assess for the sensitivity, specificity, and area under the receiver operating characteristic curve in terms of Lisfranc diagnosis against the gold standard of intraoperative testing of tarsometatarsal joint stability. Intraoperatively, the congruency and stability of the second tarsometatarsal joint had been evaluated by direct visualization and by the insertion of a probe into the joint between the base of the second metatarsus and the medial cuneiform and twisting the probe to assess for stability. The individuals evaluating the video clips were unaware of the surgically obtained diagnosis at the time they performed their evaluations. RESULTS: All 3D radiographic signs that were examined had excellent diagnostic reliability in terms of sensitivity and specificity, ranging from 92% to 97% and from 92% to 93%, respectively. When assessing the association between the suggested 3D radiographic signs and Lisfranc injury diagnosis as a function of the area under the receiver operating characteristic curve, the Mercedes sign demonstrated a higher area under the curve than the other signs did (0.91 versus 0.87 versus 0.8; p < 0.001). The mean intraobserver and interobserver reliability (kappa) values were excellent for all 3D radiographic signs that were evaluated. CONCLUSION: The proposed radiographic findings demonstrated excellent diagnostic performance and were repeatable within and among observers. Three-dimensional CT radiographic signs could function as a valuable diagnostic tool for the evaluation and initial screening for Lisfranc injury in the acute injury phase because obtaining AP bilateral standing radiographs of the foot is often impractical in the acute setting. Further research and comparison with AP weightbearing radiographs of the bilateral feet may be warranted. LEVEL OF EVIDENCE: Level III, diagnostic study.

Pearls and pitfalls of PROMIS clinically significant outcomes in orthopaedic surgery.

INTRODUCTION: Patient-Reported Outcome Measurement Information System (PROMIS) was developed as a uniform and generalizable PROM system using item response theory and computer adaptive testing. We aimed to assess the utilization of PROMIS for clinically significant outcomes (CSOs) measurements and provide insights into its use in orthopaedic research. MATERIALS AND METHODS: We reviewed PROMIS CSO reports for orthopaedic procedures via PubMed, Cochrane Library, Embase, CINAHL, and Web of Science from inception to 2022, excluding abstracts and missing measurements. Bias was assessed using the Newcastle-Ottawa Scale (NOS) and questionnaire compliance. PROMIS domains, CSO measures, and study populations were described. A meta-analysis compared distribution and anchor-based MCIDs in low-bias (NOS ≥ 7) studies. RESULTS: Overall, 54 publications from 2016 to 2022 were reviewed. PROMIS CSO studies were observational with increasing publication rates. Evidence-level was II in 10/54, bias low in 51/54, and compliance ≥ 86% in 46/54. Most (28/54) analysed lower extremity procedures. PROMIS domains examined Pain Function (PF) in 44/54, Pain Interference (PI) in 36/54, and Depression (D) in 18/54. Minimal clinically important difference (MCID) was reported in 51/54 and calculated based on distribution in 39/51 and anchor in 29/51. Patient acceptable symptom state (PASS), substantial clinical benefit (SCB), and minimal detectable change (MDC) were reported in ≤ 10/54. MCIDs were not significantly greater than MDCs. Anchor-based MCIDs were greater than distribution based MCIDs (standardized mean difference = 0.44, p < 0.001). CONCLUSIONS: PROMIS CSOs are increasingly utilized, especially for lower extremity procedures assessing the PF, PI, and D domains using distribution-based MCID. Using more conservative anchor-based MCIDs and reporting MDCs may strengthen results. Researchers should consider unique pearls and pitfalls when assessing PROMIS CSOs.

A Novel Classification for Diabetic Foot Ulcers of the First Ray.

OBJECTIVE: Diabetic foot ulcers of the first ray result from several distinct biomechanical mechanisms related to anatomical deformities, which must be addressed if surgical offloading is contemplated. The objective of this study was to create a classification of the anatomical deformities of first-ray ulcers that could lead to better standardization of treatment and reporting. METHODS: The authors performed a file review of patients with diabetic neuropathy diagnosed with first-ray ulcers over a period of 3 years in an outpatient setting. Anatomical deformities were diagnosed clinically and reported with ulcer location. The primary classification was the metatarsophalangeal joint, the interphalangeal joint, and the distal phalanx. RESULTS: Records for 59 patients (mean age, 62 years) with University of Texas A1 and A2 ulcers were reviewed. Mean ulcer duration was 2 months. The more common deformities were hallux valgus (41%), hallux valgus interphalangeus (14%), and hallux malleus (20%), and these were primarily associated with metatarsophalangeal, interphalangeal joint, and tip-of-toe ulcers, respectively (P < .0001). CONCLUSIONS: By classifying ulcer locations, the relevant corrective surgery may be chosen. Although some prophylactic procedures may be safe and effective, prophylactic hallux valgus correction in the diabetic foot requires further study.

Individualized tibial tubercle-trochlear groove distance-to-patellar length ratio (TT-TG/PL) is a more reliable measurement than TT-TG alone for evaluating patellar instability.

PURPOSE: To evaluate the intra/inter-rater and diagnostic reliability of the sagittal plane adjusted patellar instability ratios (PIRs) compared to tibial tubercle-trochlear groove (TT-TG) distance alone while employing a matched case-control analysis for age and sex to minimize a potential confounding effect. METHODS: A retrospective case-control study was performed of all knee MRI studies of patients diagnosed with patellar instability, between 2005 and 2020 at a regional tertiary medical centre. Using a 1:1 case-control matching of sex and age at the time of the diagnosis, one control subject was assigned to each case of patellar instability. Measurements of TT-TG distance, sagittal patellar length (PL), sagittal patellar tendon length (PTL), TT-TG/PL ratio, and TT-TG/PTL ratio were conducted. Two orthopaedic surgery residents and a senior musculoskeletal radiologist were assigned to assess the intra- and inter-rater reliability. Inter-class coefficients were calculated (ICC). The receiver operating characteristic (ROC) curve and area under curve (AUC) for each parameter were compared to evaluate for diagnostic reliability. Odds ratios (OR) and their 95% confidence intervals (CI) were calculated and a multivariable logistic regression model was performed to control for possible confounders. RESULTS: The study included 324 individuals (162 case-control matched pairs). In terms of intra- and inter-rater reliability, TT-TG/PL and TT-TG/PTL ratios showed an excellent correlation within and between readers (TT-TG/PL; intra-rater ICC 0.94 and inter-rater ICC 0.92, TT-TG/PTL; intra-rater ICC 0.91 and inter-rater ICC 0.88). The ROC curve showed a slightly greater AUC of the TT-TG/PL ratio compared to TT-TG distance alone (0.75 vs 0.73, p < 0.001). When applying the pathologic cutoff of TT-TG ≥ 20 mm and TT-TG/PL ≥ 0.5; the calculated odds ratios for the above cutoff were as follows; TT-TG distance alone had an OR of 14 (95% CI 1.8-106.5, p = 0.011) and OR for TT-TG/PL ratio was 23 (95% CI 3.1-170.3, p = 0.002). In the multivariable analysis, while controlling for height and weight, only the association between TT-TG/PL ratio and patellar dislocation remained statistically significant with an adjusted OR of 2.7 (CI 1.3-5.4, p = 0.006), compared to TTTG distance alone (OR = 1.9, n.s.). CONCLUSIONS: Patellar instability ratios are significantly more reliable compared to TT-TG distance alone for the evaluation of patellar instability. Patellar instability ratios present superior diagnostic reliability, sensitivity and specificity, and intra\inter rater reliability. Thus, patellar instability ratios could function as a valuable diagnostic tool for the evaluation of patellar instability. LEVEL OF EVIDENCE: III.

Lower Extremity Amputee Outcomes with Reference to Co-morbidities.

BACKGROUND: Lower extremity amputation related to diabetes is a serious outcome, which can have devastating effects on the patient and family. The epidemiology of amputations has recently been used as a possible measure of the adequacy of medical prevention and treatment of diabetes and diabetic foot complications. OBJECTIVES: To report on patients undergoing amputations at one medical center in Israel, their co-morbidities, and the outcomes. METHODS: A retrospective chart study was conducted of amputees operated between 1 September 2017 and 30 September 2018. RESULTS: The study population comprised 72 patients who had major amputations for diabetes and/or ischemia, mean age 72 ± 10 years, 74% males, 93% with type 2 diabetes. Mean age corrected Charlson Comorbidity Index was 8.2 ± 2.1 with 90% (65 patients) presenting with a score of 6 or higher. Before the recent deterioration, fewer than 20% of the patients exited their home routinely and 24% had an official diagnosis of dementia. There were 31 below knee amputations (BKA) and 41 above knee amputations (AKA). The 30-day, 3-month, 1-year, and 2-year mortality rates were 15.3%, 27.8%, 43.1%, and 54.2% respectively. Median survival period was 20 months. Survival after AKA was 13.4 ± 20, which was significantly less than after BKA (25.4 ± 2.7, P = 0.097). CONCLUSIONS: Factors other than the quality of management of patients with diabetes and complications may contribute to amputation rates; thus, making speculations from international comparisons of raw amputation rates problematic. This population was less healthy than reported in most studies.

Association between lumbosacral transitional vertebrae and spinal pathologies based on T2 whole-spine sagittal magnetic resonance imaging.

PURPOSE: To assess the association between 4, 5, or 6 lumbar spine vertebrae and the presence of lumbar spinal pathologies. METHODS: We reviewed all MRI reports and images performed between August 1st, 2018 and July 31st, 2019. Lumbar spine pathologies such as disc herniation, lytic spondylolisthesis, and spinal stenosis were recorded. The reviewer studied the T2 sagittal screening of the entire spine and counted down manually from C2 to T12 on the assumption that there are seven cervical and twelve dorsal vertebrae. We then recorded whether there were four, five, or six lumbar vertebrae. RESULTS: Our work incorporated a total of 1985 patients for whom T2-weighted entire spine sagittal MR images were obtainable. The study cohort's average age was 52.2 ± 15.9 years, comprising 944 males and 1041 females. One hundred and thirty-three patients (6.7%) had 4 lumbar-type vertebrae; 1799 (90.6%) had 5 lumbar-type vertebrae; and 53 (2.7%) had 6 lumbar-type vertebrae. There was a statistically significant difference between the rates of 6 lumbar-type vertebrae in males versus females (p < 0.05). There was a statistically significant difference with more spinal stenosis patients in the 6 lumbar-type vertebrae compared to the 4 or 5 lumbar-type vertebrae groups (p < 0.001). CONCLUSION: Our study shows that spinal stenosis is significantly more common in patients with 6 lumbar-type vertebrae.

Height Gain Prediction in Adolescent Idiopathic Scoliosis Based on Preoperative Parameters.

BACKGROUND: The purpose of the study was to identify preoperative parameters which are associated with height gain after corrective surgery for adolescent idiopathic scoliosis (AIS) and their use to preoperatively quantify the potential for height gain after AIS correction. METHODS: Our study included 87 consecutive patients with AIS who underwent posterior fusion. Patients' height was measured the day before surgery and before their discharge. Demographic and radiologic variables were analyzed for predictability of height gain. RESULTS: The mean height gain was 3.85 cm. We have found a statistically significant correlation between height gain and the following measures: preoperative thoracic curve, preoperative thoracolumbar curve, preoperative thoracic kyphosis, flexibility of the main thoracic and thoracolumbar curves, and number of fused levels (all P<0.05). Patients with Lenke type 1 and 2 had statistically less height gain compared with patients with Lenke type 3, 4, 6. CONCLUSION: Most of the scoliosis patients with Lenke type 1 and 2 will gain up to 3 cm after surgery while most of the patients with Lenke type 3, 4, 6 will gain more than 3 cm. Most patients with Lenke type 3, 4, 6 with a major curve of less than 60 degrees will gain up to 4 cm, while most of those with a major curve of more than 60 degrees will gain more than 4 cm. Patient with a positive thoracic sagittal modifier tend to have more height gain after surgery.

Healing of Chronic Wounds by Copper Oxide-Impregnated Wound Dressings-Case Series.

Novel antimicrobial wound dressings impregnated with copper oxide micro-particles have been cleared for treatment of acute and chronic wounds. Our objective is to provide preliminary data regarding the potential benefit of using these novel wound dressings including in non-infected wounds. Methods involved the treatment of wounds that responded partially or poorly to conventional wound healing treatments with copper oxide impregnated wound dressings in patients with a range of etiologies. Ten cases of patients with etiologies such as diabetes mellitus, sickle cell disease, renal failure, and necrotizing fasciitis, in which the application of copper oxide impregnated wound dressings in infected and non-infected wounds, which resulted in significant enhanced wound healing, are presented. This was exemplified by clearing of the wound infections, reduction of the fibrous and/or necrotic tissue and by intense granulation, epithelialization, and wound closure. The described 10 case reports support our hypothesis that the copper oxide-containing wound dressing not only confers protection to the wound and the dressing from microbial contamination, and in some cases may help clear the wound infections, but in addition and more importantly, stimulate skin regeneration and wound healing. Our findings are in line with previous animal and in vitro studies showing that copper plays a key role in angiogenesis and skin regeneration. These case reports support the notion that the use of copper oxide impregnated wound dressings may be an important intervention in the arsenal of wound treatment modalities, especially in hard to heal wounds.

Clinical and Radiographical Characteristics in Male and Female Adolescent Idiopathic Scoliosis Surgical Candidates.

BACKGROUND: Gender differences in adolescent idiopathic scoliosis (AIS) have been documented in curve progression, response to bracing, and outcomes of surgical treatment. However, limited information is available about the relation between gender and scoliosis curve patterns and radiographical characteristics. OBJECTIVES: To evaluate the effect of gender on curve pattern and compare clinical and radiographical characteristics between male and female patients with AIS. METHODS: We conducted a retrospective review of prospectively collected data that compared clinical and radiographical characteristics between male and female surgical candidates. Demographic and clinical data including age at presentation, gender, family history of scoliosis, brace treatment history, clinical coronal balance, shoulder asymmetry, and hump size were recorded. All patients graded their pain with the use of a visual analogue scale (VAS) on a scale from 0 to 10. Radiographs of the spine were reviewed to determine the type of curve according to the Lenke classification, Cobb angle, thoracic kyphosis angle, and the Risser sign. Radiologic coronal balance was recorded. Curve flexibility was determined by measuring the thoracic and lumbar curves magnitude on side bending radiographs. RESULTS: The study included 163 patients with AIS including 35 males and 128 females patients. Although a trend toward more flexible major thoracic curves in females was noticed, there was no statistically significant difference between the 2 groups. CONCLUSIONS: In this study we were not able to demonstrate any clinical nor radiological statistical differences between male and female patients who are candidate for surgical treatment.

Topical oxygen therapy stimulates healing in difficult, chronic wounds: a tertiary centre experience.

OBJECTIVE: Oxygen plays a central role in wound healing. Recent technological advances have miniaturised oxygen delivery systems, with novel topical oxygen therapy allowing patients to receive oxygen therapy 24 hours a day while remaining completely mobile. Here we aim to examine the efficacy and safety of continuous topical oxygen diffusion in a 'real-world' setting. METHODS: Topical oxygen therapy (TOT) was evaluated in patients with chronic, non-healing wounds in a tertiary referral specialist clinic. RESULTS: The mean wound duration before TOT was 15 months. Regardless of treatment duration, in this previously non-healing group complete wound closure was observed in 32% of the total patients treated with the TOT device. However, optimal wound healing occurred when the device was used for >25 days, with an 83% wound area reduction and 47% wound closure rate seen in venous leg ulcers (VLUs) and a 74% reduction and a 57% wound closure rate in arterial foot ulcers. CONCLUSION: Use of TOT in chronic wounds stimulates a healing state. In our study, almost half of the previously non-healing wounds closed.

Outpatient Negative-Pressure Wound Therapy Following Surgical Debridement: Results and Complications.

OBJECTIVE: To present results and complications in a case series of outpatients with diabetic and neuropathic foot ulcers with exposed bone following surgical debridement treated with negative-pressure wound therapy (NPWT). METHODS: Retrospective data were obtained from digital medical records from the Maccabi Health Services High Risk Foot Clinic in Tel Aviv, Israel, between 2009 and 2014. Medical records examined were those of clinic outpatients with exposed bone following partial foot amputation or selective bone debridement (University of Texas grade III-A) treated with NPWT. MAIN OUTCOME MEASURES: Wound area, closure rate, and adverse events. MAIN RESULTS: There were 66 patients provided NPWT in a total of 77 treatment courses. Mean patient age was 62 ± 10 years, 82% were male, and mean diabetes mellitus duration was 14 ± 8 years. Mean HbA1C levels were 8.1% ± 1.7%. Mean treatment course duration was 16 days (range, 2-42 days). Wound area decreased significantly (from 11.3 ± 16.8 cm to 8.0 ± 13.3 cm, P < .0001). Ulcer curing was noted in 7% of the cases, and healing progression was noted in 54%. Seven serious adverse events were recorded. CONCLUSIONS: Outpatient NPWT is a relatively safe and effective adjuvant to surgical debridement of neuropathic foot ulcers. In an outpatient setting, one can expect serious adverse events to occur in 10% of cases, but this seems unavoidable in patients with diabetic foot ulcers when taking into account their comorbidities and patient resources. Strict protocols to promote early recognition of complications and appropriate response to minimize deterioration must be implemented.

Bromelain-based enzymatic debridement of chronic wounds: A preliminary report.

Sharp debridement is currently considered most effective for debridement of chronic wounds; however, some patients do not have access to or cannot be treated by surgical methods. This study was designed to provide a first impression of the safety and efficacy of bromelain-based enzymatic debridement of chronic wounds. Two consecutive single-arm studies assessing the enzymatic debridement efficacy of a concentrate of proteolytic enzymes enriched in bromelain in chronic wounds was conducted in 2 medical centres. Patients were treated with up to 11 consecutive 4-hour enzymatic debridement sessions and then treated until wound closure. Twenty-four patients with chronic wounds of different aetiologies were enrolled. All wounds achieved an average of 68% ± 30% debridement in an average of 3.5 ± 2.8 enzymatic debridement 4-hour sessions. Seventeen responding wounds (venous, diabetic, pressure, and post-traumatic aetiologies) achieved an average 85% ± 12% debridement in 3.2 ± 2.5 applications. Seven non-responding wounds (arterial and post-surgical aetiologies) achieved an average 26% ± 13% debridement in 4.3 ± 3.5 applications. No treatment-related serious adverse events were observed, and the only adverse event attributed to the enzymatic debridement was pain. These preliminary results indicate the potential safety and efficacy of bromelain-based enzymatic debridement in chronic wounds. Larger controlled studies are needed to further investigate this indication.

Prospective Comparison between Remnant-Preserving Augmentation and Double-Bundle Reconstruction in Anterior Cruciate Ligament Tears.

BACKGROUND: The debate continues regarding the best way to manage partial anterior cruciate ligament (ACL) tears. OBJECTIVES: To prospectively compare the clinical outcomes of remnant-preserving augmentation (RPA) and double-bundle reconstruction (DBR) in patients with ACL tears. METHODS: In this prospective study, we included 13 cases of RPA and 30 cases of DBR with a follow-up period of 6 months, 12 months and 24 months. We clinically compared the preoperative and postoperative range of motion, Knee Society Score (KSS), Visual Analog Scale (VAS), Lysholm score, Tegner activity score, Short Form Health Survey (SF-36), thigh and calf circumference and anterior translation (Using the KT-1000 knee arthrometer). RESULTS: There were no significant differences in Lysholm score, Tegner score, VAS or KSS within the two groups at any time. The KT-1000 arthrometer results were higher in the RPA group at 6 months than in the DBR group; however, it did not reach statistical significance. CONCLUSIONS: We found no significant differences between the two specific groups leading us to believe that RPA may play a role in reconstruction when only a single bundle is injured.

The relation between location of cervical cord compression and the location of myelomalacia.

OBJECTIVE: The purpose of this study was to examine the relationship between the location of the cervical cord compression and the increased signal intensity within the cervical cord on T2-weighted imaging (T2WI) in patients with cervical myelopathy and myelomalacia. MATERIALS AND METHODS: We reviewed 1,615 MRI reports from January 2011 to May 2013 from a single institution. Of the 1,615 reports reviewed, 168 patients were diagnosed with increased signal intensity within the cervical spine on T2WI. After applying the exclusion criteria 82 patients were included in the study. The MRIs of these 82 patients were then reviewed and the location of the increased signal intensity on T2WI in relation to the location of the pressure on the spinal cord was recorded. RESULTS: In more than 50 % of the cases the lesions with increased signal intensity on T2WI either were located distal to the pressure on the spinal cord or started at the level of the pressure and extended to an area distal to the pressure. In 26 out of the 92 lesions with increased signal intensity on T2WI, the lesion started proximal to the pressure on the spinal cord and extended distal to it. In only 3 out of the 92 lesions, the lesion with increased signal intensity on T2WI was solely located proximal to the pressure on the spinal cord. In 5 other cases the lesion with increased signal intensity on T2WI started proximal to the level of pressure on the spinal cord and extended into the level of pressure on the spinal cord (p < 0.001; Table 1). CONCLUSION: Cervical myelomalacia may appear proximal, distal or at the level of the compressed cord. It rarely appears solely proximal to the pressure area on the cord.

Minimally Invasive Corrective Osteotomy (MICO) of the Hand a Novel Technique.

Introduction: Patients facing post-traumatic malunion or congenital hand differences often contend with functional and cosmetic issues. Traditional correction methods involve open osteotomy, marked by drawbacks like scarring, non-union risks, prolonged rehabilitation, and adhesions. We therefore introduce a novel minimally invasive technique called Minimally Invasive Corrective Osteotomy of the Hand (MICO), which can be performed under local anesthesia. MICO employs a low-speed, high-torque burr to address finger malunions and congenital anomalies. Case Report: A 49-year-old male patient, generally healthy and right hand dominant, presented with a post-traumatic left middle finger, middle phalanx malunion who underwent the MICO procedure, with a 1-year post-operative follow-up. Conclusion: Our findings suggest that MICO offers a straightforward, reproducible, and delicate solution for correcting hand malunions and congenital finger deformities, potentially mitigating the well-established disadvantages and complications associated with the traditional open approach. Although early results of MICO are promising, a larger case series is needed to evaluate the superiority of this technique compared with current open corrective osteotomy methods.Level of Evidence: IV.

Acceptance rate of clinical pharmacists' recommendations-an ongoing journey for integration.

Introduction: Multidisciplinary expert team collaboration in the clinical setting, which includes clinical pharmacist involvement can facilitate significant improvements in outcomes and optimize patient management by preventing drug-related problems (DRP). This type of collaboration is particularly valuable in patients with multi-morbidity and polypharmacy such as diabetic foot patients. Evidence regarding the successful integration of a new clinical pharmacist, without previous experience into a unit is still scarce. Therefore, this study aimed to describe and evaluate the actual successful integration process of the clinical pharmacist into a diabetic foot unit by measuring the change in recommendation acceptance rate over time. Methods: A prospective, exploratory treatment effectiveness study based on the recommendation acceptance rate of a new clinical pharmacist introduced into the diabetic foot unit was conducted over a 9- month period. The clinical pharmacist identified medical and drug-related problems (DRP) or any discrepancies in the prescribing and administration of medications. Each identified DRP was documented and formulated as a recommendation by the clinical pharmacist. The main outcome measure was the acceptance rate of recommendations over time. Results: A total of 86 patients, of which 67% were men, averagely aged 66.5 (SD 11.8) years were evaluated. Calculated BMI was 30.2 (SD 6.2). The average number of medical diagnoses was 8.9 (SD3.2), and 11.1 (SD 3.7) prescribed drugs for each patient. Cardiovascular disease was presented by 95% (n = 82) of the patients and 33% of them (n = 28) had uncontrolled hyperglycemia. Averagely, 3.3 (SD 1.9) DRPs were identified pre patient. The efficacy-related DRP recommendation acceptance rate increased over the study period from 37.8% in the first 4 months to 79.4% after a period of 4.75 months. Safety-related DRP recommendation acceptance rate increased from 56% to 67.6%. Conclusion: Improved clinical outcomes and optimized pharmacologic patient management may be achieved by the successful integration of a clinical pharmacist into the team. This study provides evidence of the increasing recommendation acceptance rate of integrated, pharmacist-driven comprehensive medication management in an unexperienced unit. To overcome challenges, team members should collaborate to fully integrate the clinical pharmacist into the team-based structure and utilize proper strategies to minimize and transcend barriers.

The role of three dimension computed tomography in Lisfranc injury diagnosis.

PURPOSE: To evaluate the intra/inter observer and diagnostic reliability of 3-dimensional (3D) model reconstruction computed tomography (CT) compared to the traditional two-dimensional (2D) CT when evaluating Lisfranc (LF) injuries. METHODS: A retrospective study was performed on CT studies of patients with clinically suspected LF injuries examined in the emergency department at medium size medical center. Each CT study was evaluated for metatarsal fractures and subluxations employing both standard 2D and 3D CT model reconstruction. Four orthopaedists, 2 senior and 2 residents, were assigned to review and evaluate each CT. Each CT study was reviewed twice by each reader in a randomized order. Descriptive statistics were calculated for all measured variables. The intra-observer and inter-observer agreement Kappa coefficients were calculated to evaluate reliability and reproducibility between and within readers for each modality. RESULTS: The study included 44 patients. Median age was 41.4 years (interquartile range, 23-58). The intra-observer and inter-observer reliability was good (intra-observer; 3D Kappa; 0.76 and 2D Kappa 0.73 p<0.001, inter-observer; 3D Kappa 0.68, 2D Kappa 0.63 and combined 2D and 3D kappa 0.68, p<0.001). Three dimensional CT was found to be more sensitive than 2D CT, specifically when evaluating for second metatarsal dislocation (sensitivity: 70% vs 47%). Combined evaluation of 2D and 3D CT, greatly improved sensitivity rate to 85.7%. In terms of fracture diagnosis, combined evaluation of 2D and 3D CT showed higher sensitivity and specificity rates as compared to 2D or 3D alone. CONCLUSION: The employment of 3D CT in LF injury diagnosis, in isolation and in combination with 2D CT, seems to improve the diagnostic accuracy and reliability between and within observers compared to 2D CT alone.

Return to Driving After Hip Arthroscopy: A Systematic Review and Meta-analysis.

Background: Hip arthroscopy is an increasingly common procedure; however, recommendations for safely returning to driving after hip arthroscopy vary among surgeons. Purpose: To systematically review and analyze the current available evidence on the optimal time to safely return to driving after hip arthroscopy. Study Design: Systematic review; Level of evidence, 3. Methods: A systematic review and meta-analysis was performed in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Two authors independently conducted a literature search throughout August 2021 using the PubMed, Google Scholar, Embase, and Cochrane databases. A total of 1425 articles were reviewed, and 5 articles were included. All included articles used brake reaction time (BRT) as an observer-reported outcome measure. A meta-analysis was performed to compare pre- and postoperative BRT values. Study sample sizes and mean BRT values were collected per each included study. First, data were analyzed for the right and left hips combined; then, a subgroup analysis stratified by laterality was performed. The BRT values were divided according to time periods of measurement: preoperatively and 2, 4, 6, and 8 weeks postoperatively. Results: The included studies evaluated safety to return to driving after hip arthroscopy in 160 patients. Of these, 142 patients were treated for femoroacetabular impingement, while 18 patients underwent hip arthroscopy for other diagnoses. The mean weighted age was 33.7 ± 9.0 years, 47.5% of the patients were female, and the right hip was affected in 71.2%. The preoperative range of BRT was 566 to 1960 ms, and postoperative BRT range was 567 to 1840 ms at 1 to 2 weeks and 523 to 1860 ms at 3 to 12 weeks. Meta-analysis found the studies to be moderately heterogenic (P = .06). There were no statistically significant differences in BRT between the preoperative period and at 2, 4, 6, and 8 weeks postoperatively. Conclusion: Return to driving is likely safe as early as 2 to 4 weeks after right-sided hip arthroscopy, and 2 weeks after a left-sided procedure, as driving performance returns to the preoperative level. Registration: CRD42021274460 (PROSPERO identifier).

Intrathoracic scapular dislocation following radical surgical chondrosarcoma resection from chest wall.

Locked scapula or intrathoracic scapular dislocation is an extremely rare entity encountered in the emergency department, with very few cases reported in literature. Conservative vs surgical approach in treating intrathoracic scapular dislocation is not well defined in literature. In this case report, we present a rare case of intrathoracic scapular dislocation, following multiple ribs resection due to malignant bone tumour, which was treated by closed manipulation reduction technique.
