Lateral Column Lengthening for Flexible Flat Foot: Was It Short to Begin With?

BACKGROUND: Flexible flatfoot (FF) is a common foot deformity that can often consist of foot pain. Surgical treatment is designed to lengthen the lateral column. OBJECTIVES: To resolve whether radiographic standing feet measurements of normo-plantigrade feet and FF, symptomatic or not, differ and to determine whether the lateral column is shorter. METHODS: The study comprised 72 patients (127 feet) consecutive patients, 18 years of age and older, who were divided into three groups: normal feet (56), asymptomatic FF (29), and symptomatic FF (42). All patients had a standing anterior posterior (AP) and lateral radiographs. AP images were used for the measurement of the talocalcaneal angle, talar-1st metatarsal angle, and talonavicular coverage. Lateral X-rays were used to estimate the talocalcaneal angle, talar-1st metatarsal angle, calcaneal pitch, naviculocuboid overlap, and column ratio. RESULTS: All three of the AP radiograph measurements differed among groups, and higher values were measured in the symptomatic FF group. Post hoc analysis found that the talonavicular coverage and the talocalcaneal angles also differed between symptomatic and asymptomatic FF patients. While some lateral measurements differed within groups, only the lateral talar-1st metatarsal angle distinguished between asymptomatic and symptomatic patients. The lateral column length was not found to be shorter among FF patients, weather symptomatic or not. CONCLUSIONS: Only the talonavicular coverage, the AP talocalcaneal, and the lateral talar-1st metatarsal angles were found to differ between asymptomatic and symptomatic FF patients. The lateral column was not found to be shorter.

Thickness of the Subcutaneous Fat as a Risk Factor for Surgical Site Infection Following Fragility Hip Fracture Surgery.

INTRODUCTION: Surgical site infection (SSI) following fragility hip fracture (FHF) surgery is associated with increased morbidity and mortality. SIGNIFICANCE: Prediction of patients at risk for SSI is fundamental. We aimed to determine whether subcutaneous radiographic fat measurement (SRM) is associated with increased SSI risk. METHODS: A retrospective case-control comparison of SRMs at 3 locations around the hip. Patients diagnosed with SSI in the first post-operative year were matched with age, gender, surgical year, Charlsons' co-morbidity index score, and surgical type controls, not diagnosed with SSI, at a 1:2 ratio. Measurements included the distance between (1) the sourcil to skin surface (SS), (2) the tip of the greater trochanter to skin surface (TGTS), and (3) the most prominent lateral aspect of the greater trochanter to skin surface. RESULTS: 1430 patients were operated during the study period, of whom 45 patients presented with a diagnosis of SSI and compared to 90 controls. Infections occurred 27.4 ( ± 24.8) days following surgery. SRM significantly differed between groups, and all were higher in the study group; SS, 86.8 ± 25.5 cm vs 74.2 ± 15.3 cm; TGTS, 59.8 ± 26.3 cm vs 47.0 ± 15.8 cm; and LGTS, 45.4 ± 25.1 cm vs 33.2 ± 15.1 cm (P = .003, .004, and .004, respectively). Intraclass correlation coefficients (intra-rater) were high for all measurements (.999 for all). Intraclass correlation coefficients (inter-rater) for SS, TGTS and LGTS were high, .749 (.663.815), .792 (.719.847) and .817 (.751.866), respectively. CONCLUSIONS: SRMs were found to be a valid and reproducible tool for predicting high risk of SSI in geriatric patients sustaining FHFs. LEVEL OF EVIDENCE: III.

Prevalence and Characteristics of Carriage of Neisseria meningitidis Among Young Israeli Adults.

Background: No updated data currently exist regarding Neisseria meningitidis carriage and genomic epidemiology among young Israeli adults. Methods: Oropharyngeal swabs were collected from 1801 military recruits on the day of recruitment during 2019. Neisseria meningitidis was detected and identified by culture and quantitative polymerase chain reaction (qPCR). Confirmed isolates were serotyped by qPCR, and encapsulated strains underwent whole-genome sequencing. Risk factors for carriage were determined by analyzing focused questionnaires using uni- and multivariate models. Genomic typing was performed by means of core genome multilocus sequence typing. Results: Carriage rates overall and of encapsulated strains were 20.1% and 6.7%, respectively. Genogroups B (49.2%) and Y (26.7%) were the most commonly encapsulated strains. Genogroups C, W, and X were scarce, and genogroup A was absent. The most notable clonal complexes (CCs) were CC23 (n = 30), CC32 (n = 16), and CC44/41 (n = 9). Carriage was significantly associated with smoking (odds ratio [OR], 1.82; 95% CI, 1.43-2.33) and boarding school attendance before recruitment (OR, 1.49; 95% CI, 1.14-1.96). Conclusions: The prevalence of meningococcal carriage among young Israeli adults is high, compared with similar studies in other developed countries. This might be due to sociocultural characteristics including smoking and boarding school attendance during and after high school. The dominant genogroups and CCs found were compatible with those implicated in invasive disease in Israel.

Outcome of fragility hip fractures in elderly patients: Does diabetes mellitus and its severity matter?

AIMS: Diabetes mellitus (DM) and osteoporosis are both diseases of epidemic proportions with an increasing incidence worldwide. Fragility hip fractures (FHF) are associated with elevated morbidity, mortality, social burden and medical costs. The aim of this study was to determine whether patients with DM have worse medical and surgical outcomes following FHFs and whether the Diabetes Complications Severity Index (DCSI) can predict in-hospital complications and one-year mortality. METHODS: A single centre retrospective cohort study including 1343 patients older than 65 years who underwent surgery for FHFs was conducted. The data collected included length of hospital stay, time-to-surgery, blood loss, complications and mortality during the first post-operative year. RESULTS: 408 patients with a DM diagnosis were compared with 935 without DM. Pre-operatively, patients with DM had lower haemoglobin levels, higher platelet counts and worse renal function. Following surgery, patients with DM were more likely to be transferred to another department or intensive care. One-year mortality was significantly higher in the DM group [23.3% vs. 17.1%, odds ratio 1.36 (CI 1.029-1.799, p = 0.03)]. Higher DCSI scores were related with elevated one-year mortality rates in the DM group. Cerebrovascular events were found to be nearly five times more prevalent in the DM group. Patients with DM were more likely to continue treatment in a rehabilitation centre and had a higher probability to be re-hospitalized in the first post-operative year (p.<0.001). CONCLUSIONS: Our results emphasize the increased vulnerability of this patient population and the importance of specialized care during the peri-operative period of FHFs.

Prediction of readmissions in the first post-operative year following hip fracture surgery.

PURPOSE: To define risk factors for rehospitalization following fragility hip fractures and to create a predictive model. METHODS: A retrospective cohort study of patients 65 years and older, who were treated operatively following fragility hip fractures between 01.2011 and 06.2016. Patients were allocated into two study groups based on the occurrence of recurrent hospitalizations in the year following surgery. Demographic information, comorbidities, and in-hospital characteristics were collected, as was information regarding 1-year readmissions. Multivariate analysis of factors predictive of rehospitalizations was performed, followed by a logistic regression using all predictors with p < 0.05. A stepwise backwards elimination method was used to create the predictive model. RESULTS: Eight hundred and fifty-one patients were included; 369 (43.4%) had recurrent hospitalizations within the first post-operative year. Patients who were rehospitalized were more likely to be males, to use a walking aid and to live dependently. They had a higher age-adjusted Charlson's comorbidity index (ACCI) score, a higher perveance of atrial fibrillation, lower hemoglobin, worse renal function, less platelets, and longer time to surgery. Prevalence of in-hospital complications was similar. Six variables were found to independently influence the chance for readmissions: male gender, the use of a walking aid, higher ACCI score, lower hemoglobin, atrial fibrillation, and a longer surgical delay. Only the first four were found to be adequate predictors and were added to the prediction formula. CONCLUSION: High 1-year readmission rates are seen following discharge in patients with fragility hip fractures. Addressing risk factors might aid to better rehabilitate patients and reduce morbidity.

Case Report of a New Headache Developed by a Combat Soldier after an Episode of Exertional Heat Illness.

Only a few authors have reported about a new-onset headache among patients who sustained an episode of an exertional heat illness (EHI). This report presents a healthy and physically fit 20-year-old male who developed a completely new headache after an EHI event. The new headache could be aggravated or called by exertion or exposure to sun and environmental heat. It was severe enough to interfere with even moderate physical activity, but reacted well to a few hours' rest and OTC pain medications. An extensive work-up including laboratory blood tests, lumbar puncture, head CT, and CT angiogram was negative. The patient remained symptomatic on the 6-month follow-up. Continued abstinence from physical activity and waiting for spontaneous resolution were recommended. We suggest that the headache may be secondary to the hyperthermia brain damage during the EHI event and differs from exertional headache by its association with exposure to sun and environmental heat.
