Influence of the Phenylephrine Test in Outcomes of External Levator Advancement for Involutional Ptosis.

This study aims to evaluate the influence of preoperative phenylephrine testing on the surgical outcome of patients undergoing surgery for involutional ptosis by external levator advancement. This was an observational, monocentric, retrospective study. Fifty-one eyelids from 32 patients, who had surgery between January 2018 and May 2023, were included for analysis. Preoperative clinical examination data were collected. Evaluation was performed at 1 month postoperatively. Surgical success was defined by a postoperative margin reflex distance between 3 and 5 mm inclusive. Symmetry success was defined by a difference in margin reflex distance between the 2 upper eyelids of no more than 1 mm. The surgical success rate was 86%. A positive preoperative phenylephrine test was significantly associated with a better surgical success rate (p = 0.01), including on symmetry (p = 0.01). The secondary outcomes, namely preoperative margin reflex distance, function of the upper eyelid levator muscle, and unilaterality of surgery, were not statistically associated with surgical outcome. The phenylephrine test is a predictive factor of surgical success in patients undergoing external levator advancement. Our study suggests that patients with a negative phenylephrine test should be overcorrected intraoperatively.

THE USE OF LABORATORY CRITERIA IN THE RISK ASSESSMENT OF POSTOPERATIVE COMPLICATIONS AFTER TRANSPEDICULAR FIXATION OF THE LUMBAR SPINE

Objective. To investigate the peculiarities of the development of postoperative complications after surgical treatment of degenerative diseases of the lumbar spine with transpedicular fixation of the vertebrae and their relationship with changes in preoperative laboratory parameters. Methods. A retrospective analysis of the biochemical examination data of 35 patients with degenerative diseases of the lumbar spine who underwent discectomy with transpedicular fixation was performed. In four groups of patients with postoperative complications: 10 patients — inflammation of the what fabrics around metal structures and 5 patients — instability of the metal structure. The results of the examination of 20 people without specified complications served as a comparison group. Comparison was made with a control group (20 practically healthy people). Results. Patients have a significant increase in serum ALT activity by 42.29 and AST by 63.55 %, by 38.37 % of the level of CS content, by 37.21 % of total glycoproteins compared to those in the control group. In patients with soft tissue inflammation around the serum instrument zone, the content of LDLP was recorded by 29.27 %, by 23.53 % of the UA, by 12.34 % of TP results higher by 32.01 % ALT activity and 83 %, 49 % AST, 54.96 % AlP activity, 31.40 % — AlP/AcP, 60.47 % — concentration of CS, 95.57 % — total glycoproteins than in persons in the control group. In the serum of patients with the development of instability of metal structures, 28.55 % was observed by activity of the ALT, AlP — by 38.47 %, AcP — by 48.84 %, less by 58.35 % of AlP/AcP, the CHOL content of 13 88 %, higher by 25.43 % of the LDLP content than such persons in the control group. Content of the P was lower by 31.51 % and the Ca/P ratio was higher by 38.95 %, the content of CS by 83.72 %, total glycoproteins — by 48.83 %. Conclusions. Comparative analysis of the results of preoperative clinical and laboratory examination of patients with degenerative spinal diseases with transpedicular fixation which is reflected in the deviations of their preoperative laboratory parameters from such persons with uncomplicated course of the postoperative period after similar surgery.

Diagnostic spectrum of cysts of head and neck: Case series and review of literature

One of the foremost problems that brings patients to Otorhinolaryngology clinics are cystic swellings in the head and neck region. We aimed to study the presentation, configuration of cystic swellings of head and neck for diagnosis and management. A retrospective study of 30 patients belonging to diverse age group and presenting with complaints of swelling in the craniofacial domain to the otorhinolaryngology outpatient department was conducted. Based on the characterization of cystic swellings of head and neck, most turned out to be usually benign. The most common cyst was epidermoid cyst (56%), followed by second arch branchial cyst (26%). A single case each of nasopalatine cyst and intra-parotid lymphatic cyst was also reported. Swellings in the head and neck can have various presentations. Cytologic examination of head and neck cysts along with pre-operative clinical examination and imaging offer imperative information concerning the nature of the cystic lesions, and may rarely lead to any misdiagnosis.

Intraoperative neuromonitoring potentials and evidence of preserved neuronal circuitry below the anatomical and functional level in patients with complex spinal dysraphism undergoing detethering reoperations.

Spina bifida represents one of the most common birth defects, occurring in approximately 1-2 children per 1000 live births worldwide. The functional level of patients with spina bifida is highly variable and believed to be correlated with the anatomical level of the lesion. The variable clinical picture is well established, but the correlation with anatomical level and intraoperative neuromonitoring (IONM) data has not been investigated. Furthermore, the potential for preserving function beyond the apparent clinical level has also not been investigated. The objective of this research was to determine the presence and level of intraoperative transcranial motor evoked potential (tcMEP) and triggered electromyography (tEMG) responses, and the association of these responses with preoperative clinical function and radiographic data in pediatric cases of complex tethered cord release reoperations. A single-center retrospective review of pediatric patients with complex spinal dysraphism undergoing detethering reoperations was conducted. Preoperative demographic and clinical data, including the radiographic and clinical level of dysraphism, were collected. IONM, including tcMEPs and tEMG responses, were obtained and compared with preoperative clinical data. Descriptive analysis was performed, by patient for demographics and by case for surgeries performed. In 100% of 21 cases of complex detethering reoperations, representing 20 patients, intraoperative tcMEPs could be generated at (4.8%) or below (95.2%) the level of clinical function. Compared with the preoperative clinical examination, 5 cases (23.8%) demonstrated tcMEP responses that were 1 level below the clinical function level, 11 cases (52.4%) were 2 levels below, and 4 cases (19.0%) were 3 levels below. Overall, 18 of 21 cases showed tEMG responses at or below the level of clinical function; of these, 7 cases (33%) were 1 level below and 3 (14%) were ≥ 2 levels below the clinical function level. The presence of positive stimulation potentials below the level of clinical function in patients with complex spinal dysraphism undergoing detethering reoperations indicates a degree of preserved neuronal connectivity. These findings suggest novel future treatment approaches for these patients, including using devices targeted to stimulation of these neurological pathways.

Invasive solid papillary carcinoma of breast mimicking as a benign condition: Rare case report

Invasive papillary carcinomas of breast are rare tumors. They account for approximately 0.5% of all Invasive breast carcinomas. Invasive papillary carcinomas are commonly present in post-menopause women. These tumors lack the myoepithelial cell layer (MCL) within the papillae or at the periphery of the tumor. The diagnosis is difficult due to different clinical and radiological features. Immunohistochemistry (IHC) is really essential to confirming the diagnosis. We are here presenting one index case of a rare variety of invasive papillary carcinoma of the left breast. We present a case of invasive papillary carcinoma of the left breast in a 55-year-old female presented with a retroareolar lump without nipple discharge. Preoperative core biopsy showed fibroadenoma with a papillary configuration.But post-operative histopathological examination revealed it was an invasive papillary carcinoma. Invasive papillary carcinoma of breast even though a rare entity, making a diagnosis is very challenging. Thorough preoperative clinical and radiological examination should be done, so that timely management as well as proper treatment is possible.

Role of Magnetic Resonance Imaging in Pelvic Organ Prolapse Evaluation.

Background and Objectives: The primary method for assessing pelvic floor defects is through physical examination. Magnetic resonance imaging (MRI) is a radiological technique that is useful for identifying the underlying defects of pelvic floor structures that require surgery. The primary aim of this study was to find correspondence between the clinical and radiological staging of pelvic organ prolapse (POP) before and after vaginal surgery. A secondary endpoint was to investigate, through clinical and MRI findings, whether surgery influences continence mechanisms. Finally, we reported changes in the quality of life of women who underwent surgery for prolapse. Materials and Methods: Twenty-five women with prolapse stage ≥ 2 POP-Q were recruited in this prospective study. They underwent preoperative clinical examination, MRI at rest and under the Valsalva maneuver, and quality of life questionnaires. Three months after vaginal surgery, they repeated clinical and radiological evaluation. Results: Twenty women completed the study. Both clinical and MRI evaluations showed an improvement in prolapse and symptoms after surgery. There were some discrepancies between clinical and radiological staging. MRI parameters did not show differences between pre- and postoperative values at rest; under the Valsalva maneuver, instead, the measurements changed after surgery. Continence was not worsened by the widening of the vesicourethral angle. Patients reported an improvement in quality of life. Conclusions: MRI is an accurate and objective method for defining the stage of prolapse, but clinical evaluation alone is sufficient for staging prolapse before surgery and evaluating the result at follow-up. It is an accurate method for visualizing some pelvic structures that can be compromised because of pelvic organ prolapse. MRI showed that vaginal surgery does not affect continence mechanisms.

Evaluation of outcomes of lower eyelid entropion and ectropion surgical repair.

<b><br>Introduction:</b> The imbalance of external and internal forces acting on the lower eyelid can result in entropion and ectropion, both of which cause ocular irritation and loss of proper eye protection. Potential complications of untreated cases include recurrent inflammation of the conjunctiva and cornea, conjunctival neovascularization, corneal abrasion or perforation, and ultimately even loss of vision. Although various surgical techniques are used to address this problem, their long-term outcome and effectiveness are still under discussion. </br> <b><br>Aim:</b> To evaluate outcomes of surgery for entropion and ectropion, including a modified Wheeler's method for entropion correction.</br> <b><br>Methods:</b> A non-comparative study (prospective and retrospective groups) included 100 patients operated on in two university hospitals' plastic surgery departments for lower eyelid entropion or ectropion, following formal ethics approval. The prospective group included 50 patients assessed preoperatively and at 3 and 12 months postoperatively. The retrospective group was comprised of 50 patients (2012-2018), whose preoperative documentation and clinical examinations were analyzed. The main outcome measures were change between pre- and postoperative patient-reported symptoms (VAS scale), ectropion/entropion grading scale (EGS/EnGS), quality of life (WHOQOL-BREF), and occurrence of complications.</br> <b><br>Results:</b> The differences in the severity of all symptoms before and after surgery evaluated with the VAS scale were statistically significant in both groups (p <0.05). We observed 6 recurrences (12%) in the prospective group and 9 (18%) in the retrospective group, with minor complications. Very good functional and esthetic postoperative results were confirmed in 70% (79) of the whole group and in 13 patients (81.3%) treated with the modified Wheeler's method. In the prospective group, the Mann- Whitney U test for dependent variables revealed significant improvement in the somatic, psychological, and environmental domains, with no significant change in the social relationships domain.</br> <b><br>Conclusions:</b> The results following entropion/ectropion surgery prove the effectiveness of the methods used. Complementing them with the modified Wheeler's method brought an increase in the number of very good outcomes. Surgery of lower eyelid malposition contributed to reduced symptoms and improved quality of life. The rates of postoperative sequelae were low.</br&gt.

Comparative study of benign and malignant parotid gland tumors by infrared thermal imaging

Objective: To analyze the temperature difference of benign and malignant parotid gland tumors in preoperative infrared thermography (IRT), and to provide the basis for predicting tumor properties. Methods: The clinical data of 98 patients with parotid gland tumor admitted to the Department of Oral and maxillofacial Surgery of the First Affiliated Hospital of Bengbu Medical College, from May 2021 to April 2023 were retrospectively analyzed. There were 61 males and 37 females, aged (51.1±16.0) years (10-86 years). In addition to routine examination, the temperature difference between the lesion site of parotid gland and the contralateral mirror area was measured by infrared thermal imager in all patients one day before surgery. The maximum diameter (dmax) and location of the tumor (deep or superficial lobe) were recorded according to preoperative clinical examination and imaging examinations such as CT and ultrasound. The patients were divided into three groups by tumor size: dmax≤2 cm, 2 cm<dmax≤4 cm, dmax>4 cm. The patients were also divided into different groups: deep lobe group and superficial lobe group (according to the tumor location), benign group and malignant group (according to postoperative pathological results). The relationship between temperature difference, pathology, size and location was analyzed. Results: There were 79 cases in the benign group and 19 cases in the malignant group. The temperature difference of the healthy and affected side in the malignant group [(1.73±0.21) ℃] was significantly higher than that in the benign group [(0.73±0.32) ℃] (t=16.70, P<0.001). There was no significant difference in temperature difference between the healthy and affected sides of tumors with different diameters (P>0.05). The temperature difference of healthy and affected side of tumor in superficial lobe [(0.97±0.50) ℃] was significantly higher than that in deep lobe [(0.67±0.44) ℃] (t=2.24, P=0.028). Conclusions: The difference of temperature difference between benign and malignant parotid gland tumors detected by IRT is statistically significant, which can be used to predict tumor properties, and has certain clinical application value.

Outcomes of Sentinel Lymph Node Biopsy for Patients With Node-positive Breast Cancer Treated With Neoadjuvant Chemotherapy.

Clinical trials have shown that the sentinel lymph node biopsy (SLNB) is feasible for patients with cN1 breast carcinoma treated with neoadjuvant chemotherapy (NAC). This study aimed to evaluate the technical outcomes of SLNB by assessing the volume of residual nodal disease. All patients with cT1-3 cN1 breast cancer undergoing NAC from January 2018 to December 2021 were retrospectively identified from our institutional database. We assessed the outcomes of preoperative clinical examination, ultrasonography, and other imaging to predict the axillary nodal status after NAC for patients converted to cN0 and undergoing SLNB; both adequate mapping and false-negative rate (FNR) at intraoperative evaluation of SLN were assessed. Overall 160 patients were included in the study; 98 were converted to cN0 and underwent SLNB. No difference was found in the adequate mapping rate nor in the mean number of SLNs retrieved compared to the residual LN burden. The intraoperative SLN FNR was 38.2%, with smaller nodal volume being associated with lower FNR (p<0.01). The positive predictive values of physical examination and imaging-based nodal assessment post-NAC were 87.1% and 68.2%, respectively. In a significant percentage of patients with cN1 disease converted to cN0 after NAC, it was possible to recover three or more SLNs. The residual volume of LN disease did not impact the SLN mapping rate. However, we found a high FNR for intraoperative SLN evaluation, particularly for patients with small residual nodal disease. It seems that only a small proportion of patients eligible for SLNB after NAC can be spared ALND.

Safety and Efficacy of a Novel Polyglycolic Acid Meniscal Scaffold for Irreparable Meniscal Tear.

Meniscal tears treated with a partial meniscectomy could induce knee osteoarthritis, thereby altering or damaging knee kinetics and biomechanics. We have developed a meniscal scaffold made of polyglycolic acid (PGA) coated with polylactic acid/caprolactone (PGA scaffold), which could induce new tissue growth of meniscus-like tissue. This study aimed to evaluate the safety and efficacy of a novel meniscal scaffold for the treatment of irreparable meniscal injuries. This study describes the findings of a cyclic torque test and first clinical trial of a PGA scaffold for inducing meniscus-like tissue in humans. As the first step, biomechanical testing of the PGA scaffold was performed using a cyclic torque test. Six patients underwent arthroscopic implantation of the PGA scaffold. Furthermore, the patients underwent preoperative clinical, serological, radiographic, and magnetic resonance imaging examinations at 3, 6, and 12 months postoperatively. The patients also underwent a second-look arthroscopy 12 months after implantation. Torque increased with increasing cyclic loading. However, no structural damage to the sample was noted after 70,000 loading cycles. All patients showed improvement in pain, Lysholm scores, Tegner activity scores, International Knee Documentation Committee, and knee injury and osteoarthritis outcome. The second-look arthroscopy revealed that meniscal tissue had regenerated in 5 patients (83%). Radiography and magnetic resonance imaging confirmed no progression of degenerative joint disease. The PGA scaffold could tolerate shear forces, did not produce safety concerns, and may have therapeutic potentials for irreparable meniscal tears in humans.

Long-term results of arthroscopic repair of type II SLAP lesions in sports: assessment of return to pre-injury playing level and critical risk factors for complication

PurposeThe management of isolated SLAP lesions is still debated especially in athletes. Aims of the study were: 1. to analyse our algorithm to treat SLAP lesions starting from the selection of patients for surgery and 2. to correlate the familiarity for diabetes and hypothyroid disorders with post-operative results.MethodsSeventy-eight patients with isolated SLAP lesion were arthroscopically treated using knotless anchors and microfractures. All patients had a pre-operative and post-operative clinical examination according to Walch–Duplay, Constant, Rowe and Dash scores and interviewed for familiarity to diabetes and hypothyroid disorders.ResultsAbout 68.8% of patients solved pain with rehabilitation. About 29% of patients returned to the sports activities. About 32% of patients were no responder to physiotherapy and were arthroscopically treated. About 53.9% of patients responded excellent, 34.7% good, 3.8% medium and 7.6% poor results according to Walch–Duplay score. The Constant score increased from 64 to 95, the Rowe score from 48 to 96. The outcomes were significantly worse in patients with familiarity for diabetes.ConclusionsMicrofractures and knotless anchor give long-term good results for the treatment of SLAP lesions in athletes. The familiarity for diabetes is an important risk factor that can lead to decreased outcomes.

Clinical, Radiological and Histological Features and Their Association with Extranodal Extension in Buccoalveolar Complex Squamous Cell Carcinoma.

Jeyashanth RijuObjectives The study was aimed to (1) evaluate the effectiveness of clinical examination, intraoperative finding, and contrast-enhanced computed tomography (CECT) to detect extranodal extension (ENE) in buccoalveolar complex squamous cell carcinoma (BAOSCC), (2) to know various factors influencing ENE, and (3) to evaluate survival outcome in patients with ENE. Materials and Methods This was a retrospective cohort study, which included 137 patients with BAOSCC who underwent curative treatment between May 2019 and April 2021. Collaborative findings suggestive of ENE were noted during preoperative clinical examination, CECT, and intraoperatively, and their efficacy was compared with postoperative histopathology. Also, the various factors associated with ENE were evaluated and compared. Statistical Analysis Univariate and multivariate analysis of parameters was done using multiple logistic regression analysis and significant correlation was determined using chi-square test between ENE positive and negative categories. Analysis of prognosis and survival was done by Kaplan-Meier curve plotting using regression analysis and its significance was compared. Results The overall prevalence of ENE was 18.98% and that of lymph node involvement was 40.88%. CECT (73.1%) was found to be more sensitive in detecting ENE compared to intraoperative examination (46.2%) and clinical examination (34.6%).In comparison with clinical examination (91.9%) or CECT (78.38%), intraoperative examination (93.7%) showed the highest specificity in detecting ENE. Clinical nodal size ≥ 3 cm ( p ≤ 0.001), fixity ( p ≤ 0.001), and clinical number of nodes ( p ≤ 0.001) had significant association with ENE. The presence of thick nodal walls on CECT increased the probability of predicting ENE 15 times ( p = 0.180, confidence interval: 0.3-765.4). After a mean follow-up of 18 months, subjects without nodal positivity had a survival advantage over patients with positive lymph nodes (86.4% vs. 53.3%) and those with ENE (86.4% vs. 23.2%), respectively. Conclusion The results demonstrated that clinical examination can be used as an adjuvant to radiological imaging for prediction of ENE preoperatively. Clinical finding suggesting size of node ≥ 3 cm and ≥ 2 nodes are strong predictor of ENE, in addition to other known predictors. Patients with ENE had an unfavorable prognosis when compared with subjects with metastatic nodes without ENE. Presence of ENE remains one of the strongest factors predicting recurrence and thus poor prognosis.

Variability in Cochlear Implantation Outcomes in a Large German Cohort With a Genetic Etiology of Hearing Loss.

The variability in outcomes of cochlear implantation is largely unexplained, and clinical factors are not sufficient for predicting performance. Genetic factors have been suggested to impact outcomes, but the clinical and genetic heterogeneity of hereditary hearing loss makes it difficult to determine and interpret postoperative performance. It is hypothesized that genetic mutations that affect the neuronal components of the cochlea and auditory pathway, targeted by the cochlear implant (CI), may lead to poor performance. A large cohort of CI recipients was studied to verify this hypothesis. This study included a large German cohort of CI recipients (n = 123 implanted ears; n = 76 probands) with a definitive genetic etiology of hearing loss according to the American College of Medical Genetics (ACMG)/Association for Molecular Pathology (AMP) guidelines and documented postoperative audiological outcomes. All patients underwent preoperative clinical and audiological examinations. Postoperative CI outcome measures were based on at least 1 year of postoperative audiological follow-up for patients with postlingual hearing loss onset (>6 years) and 5 years for children with congenital or pre/perilingual hearing loss onset (≤6 years). Genetic analysis was performed based on three different methods that included single-gene screening, custom-designed hearing loss gene panel sequencing, targeting known syndromic and nonsyndromic hearing loss genes, and whole-genome sequencing. The genetic diagnosis of the 76 probands in the genetic cohort involved 35 genes and 61 different clinically relevant (pathogenic, likely pathogenic) variants. With regard to implanted ears (n = 123), the six most frequently affected genes affecting nearly one-half of implanted ears were GJB2 (21%; n = 26), TMPRSS3 (7%; n = 9), MYO15A (7%; n = 8), SLC26A4 (5%; n = 6), and LOXHD1 and USH2A (each 4%; n = 5). CI recipients with pathogenic variants that influence the sensory nonneural structures performed at or above the median level of speech performance of all ears at 70% [monosyllable word recognition score in quiet at 65 decibels sound pressure level (SPL)]. When gene expression categories were compared to demographic and clinical categories (total number of compared categories: n = 30), mutations in genes expressed in the spiral ganglion emerged as a significant factor more negatively affecting cochlear implantation outcomes than all clinical parameters. An ANOVA of a reduced set of genetic and clinical categories (n = 10) identified five detrimental factors leading to poorer performance with highly significant effects ( p < 0.001), accounting for a total of 11.8% of the observed variance. The single strongest category was neural gene expression accounting for 3.1% of the variance. The analysis of the relationship between the molecular genetic diagnoses of a hereditary etiology of hearing loss and cochlear implantation outcomes in a large German cohort of CI recipients revealed significant variabilities. Poor performance was observed with genetic mutations that affected the neural components of the cochlea, supporting the "spiral ganglion hypothesis."

Evaluation of outcomes after conservative mandibular surgery in patients with oral squamous cell carcinoma

This study aimed to assess preoperative radiological and clinical examinations for identifying bone status and to evaluate survival outcomes in patients undergoing marginal mandibulectomy for the primary treatment of oral squamous cell carcinoma. The medical records, enhanced computed tomography (CT) scans, and pathological specimens of these patients were reviewed. Disease-free (DFS), local recurrence-free (LRFS), and osteoradionecrosis-free (ORNFS) survival were analysed. The study included 104 patients. The preoperative CT and clinical examinations achieved a sensitivity of 45.8% and specificity of 100% for judging bone condition. LRFS was 79.6% and DFS was 68.8%. Pathological bone invasion in significantly affected DFS (P = 0.597), while DFS was significantly higher for those with a lower clinical tumour stage (1/2 vs 3/4; P = 0.005) and postoperative radiotherapy (P = 0.011). Among 39 patients receiving postoperative radiotherapy, ORNFS was 75.2%. Postoperative chemotherapy significantly decreased ORNFS (P = 0.009). Tumour subsite (P = 0.003) and the resection site (P = 0.035) significantly affected the remaining bone height. The results indicate that CT and clinical examinations cannot precisely identify superficial bone damage, but work well in selecting patients for marginal resection. Adhering to current indications, this resection approach can guarantee safe bone margins in terms of survival outcomes.

Analysis of surgical treatment of appendix neuroendocrine neoplasms—17 years of single-center experience

Background/aimThis study investigated the clinicopathological characteristics and treatment of appendix neuroendocrine neoplasms in appendectomy specimens of our center.Materials and methodsThe clinicopathological data, including age, sex, preoperative clinical manifestation, surgical method, and histopathological examination results of 11 patients with appendix neuroendocrine neoplasms confirmed by surgery and pathology between November 2005 and January 2023, were retrospectively analyzed.ResultsIn the histopathological examination of 7277 appendectomy specimens, 11 cases (0.2%) had appendix neuroendocrine neoplasms. Among the 11 patients, 8(72.7%) were males, and 3(27.3%) were females, with an average age of 48.1 years. All patients underwent emergency surgery. A total of 9 patients underwent open appendectomy, including 1 patient who underwent second-stage simple right hemicolectomy after an appendectomy, and two who underwent laparoscopic appendectomy. All 11 patients were followed up for a period of 1 to 17 years. All patients survived without any indication of tumor recurrence.ConclusionAppendiceal neuroendocrine neoplasms are low-grade malignant tumors originating from neuroendocrine cells. They are rarely seen in clinical practice and are often treated based on acute and chronic appendicitis symptoms. These tumors are challenging to diagnose before surgery due to the lack of specificity in clinical manifestations and auxiliary examinations. The diagnosis generally depends on postoperative pathology and immunohistochemistry. Despite the diagnostic challenges, these tumors have a favorable prognosis.

Functional scores and prosthetic implant placement are different for navigated medial UKA left in varus alignment.

The purpose of this study was to analyze the clinical outcomes and radiologic position of the knee in two groups of patients after medial unicompartmental knee arthroplasty (UKA): one group with residual varus axis (RVA) alignment and other one with neutral mechanical axis (NMA) of the lower limb. All patients who underwent UKA between January 2015 and January 2018 were evaluated retrospectively. Inclusion criteria were: medial UKA for isolated medial femoro-tibial osteoarthritis, a varus deformity of < 15°, and a minimal follow-up of 2years. All patients had a preoperative and postoperative clinical examination with functional scores (New International Knee Score (NewIKS) and Knee injury and Osteoarthritis Outcome Score (KOOS) and radiographs. Preoperative and postoperative values for continuous outcomes were compared using the Student's t test for paired data and differences between the groups were compared with the Mann-Whitney U test. p < 0.05 was considered statistically significant. The RVA group consisted of 48 cases of medial UKA in 48 patients (22 females). Mean postoperative hip-knee-ankle (HKA) angle was 174.3° ± 2.8 and the corresponding mean AKI angle (tibial mechanical angle) was 82.9° ± 2.9. The NMA group consisted of 35 cases of medial UKA in 35 patients (14 females). Mean postoperative HKA angle was 178.9° ± 3 and the corresponding mean AKI angle was 85.5° ± 3.1. A significant difference was found between the two groups for the KOOS score and for global NewIKS, with a better score in the RVA group. RVA alignment after medial UKA results in a significant improvement in functional knee scores at 2-year post-surgery. Return to sport and recreational activities was better than in patients with postoperative NMA. Level 3; retrospective cohort study.

The Hand Hug: A Novel Test for Linburg-Comstock Syndrome and Wide-awake Correction of the Anomaly.

In 1979, Linburg and Comstock1 described an inability to flex the interphalangeal joint of the thumb without simultaneously flexing the distal interphalangeal joint of the index finger, caused by a congenital anomalous connection between the flexor pollicis longus tendon and the flexor digitorum profundus tendon to the index finger. The “hand hug test” is a novel clinical test for this condition. The palm of the affected hand of the patient is placed on the ipsilateral palm of the examiner’s hand with all the digits lined up in extension. The thumbs are abducted. The patient is asked to bend the thumb around the examiner’s hand while the examiner does the same action—as if the hands are “hugging.” Because the index finger of the patient and the small finger of the examiner are aligned and blocking each other in extension, the thumb of the patient with the Linburg-Comstock anomaly is not able to make a “hand hug.” We report the case of a 20-year-old, right-hand dominant carpentry student who had a complete inability to move his right thumb and right index finger independently. The patient did have the anomaly on the contralateral side, but it was far less pronounced. Specific activities affected by the anomaly were piano, typing, and rock climbing. The phenomenon had always been present but was progressively becoming more pronounced, with no clear history of an inciting traumatic event. We performed a point-of-care ultrasound examination and observed a pathologic band in both the coronal and sagittal view, which was 4 cm in length. We agree that magnetic resonance imaging or computed tomography scan can be helpful to characterize the anatomy, but high-frequency ultrasonography is sufficient to localize the congenital band.2 We performed wide-awake surgery with subcutaneous local anesthesia infiltration of 10 mL lidocaine 1% with 10 mg/mL of epinephrine with 20 mL saline buffered with 2 mL 8.3% bicarbonate [wide awake local anesthesia no tourniquet (WALANT) technique].3 The local anesthesia was allowed at least 45 minutes to take effect before the procedure. The patient was positioned supine with the affected limb on an arm board without a tourniquet. The surgical field was prepared and draped using field sterility. A linear incision was made along the radial aspect of the distal forearm over the flexor carpi radialis tendon, just proximal to the volar wrist crease. The anomalous connection was confirmed by the synkinesis of the tendons on both active and passive intraoperative testing. We observed the fibrous type anomalous connection, which is the most common type among the classification of Yurasakpong et al.4 We sharply divided the connection, which immediately corrected the anomaly. The thumb and index finger could now move independently, and the patient was able to make the “hand hug” with the surgeon [See Video (online), which displays the preoperative clinical and ultrasound examination, surgical procedure, and final result with the “hand hug test” for each step]. The patient was mobilized immediately, using principles of hand elevation, early cessation of postoperative analgesics, and “pain-guided healing.” Hand therapy was used to encourage independent tendon gliding. He made a complete recovery and was able to return to normal activities without restrictions. {"href":"Single Video Player","role":"media-player-id","content-type":"play-in-place","position":"float","orientation":"portrait","label":"Video 1.","caption":"This video displays the preoperative clinical and ultrasound examination, surgical procedure and final result with the « hand hug test” for each step.","object-id":[{"pub-id-type":"doi","id":""},{"pub-id-type":"other","content-type":"media-stream-id","id":"1_pcsm1wze"},{"pub-id-type":"other","content-type":"media-source","id":"Kaltura"}]} PATIENT CONSENT The patient provided written consent for the use of his image.

Management of orbital floor fractures in France: Results of a national online survey

IntroductionOrbital floor fractures (OFF) are common facial trauma injuries, and there are no official guidelines for their medical and surgical management. The aim of this study was to provide an overview of the management of OFF in France. Materials and methodsAn online questionnaire was sent to 144 surgeons at the 88 French centers involved in the management of OFF (2019 data from the National Health Insurance Body). The questions related to the preoperative clinical and radiographic examinations, the criteria for surgical indication, the materials used, and the elements of the postoperative period. ResultsUltimately, 42 questionnaires were analyzed (32 from oral and maxillofacial surgeons (OMFS), 8 from ophthalmologists, and 2 from ENT or plastic surgeons). For 69% of the surgeons, a systematic ophthalmological examination was carried out, 3–7 days after the trauma, and based on a Lancaster test or visual acuity (97.6% and 83.3% of the responders, respectively). The most important criteria for the therapeutic decision were diplopia or oculomotor disorder that persisted for more than 7 days (76.2%), clinical enophthalmos (54.8%), a large fracture (52.4%), and ptosis of the orbital content on CT scan (38.1%). The mean surgical delay was 7–15 days for 54.8% of the responders. Resorbing sheets were the preferred materials to repair small fractures, while larger fractures required alloplastic implants (titanium mesh). ConclusionThis survey confirms the diversity of practices in France regarding the management of OFF. Further studies are needed before guidelines can be developed.
