МЕТОДИКА КОМПЛЕКСНОЙ ОЦЕНКИ ИСКУССТВЕННЫХ КОРОНОК В ПОЛОСТИ РТА

According to statistics collected by domestic and foreign authors, the number of patients in need of orthopedic treatment is increasing every year. [7,8] Modern dental prosthetics includes not only an integrated approach to rehabilitation and restoration of lost functions, but also a high level of aesthetics of the prostheses themselves, which has a significant impact on the comfort and quality of life of dental patients [7,8,15]. The patient's subjective satisfaction with the result of treatment is one of the main tasks of an orthopedic dentist, no less important than rational prosthetics itself. Thus, in order to achieve success, it is necessary to carefully analyze the initial clinical situation, draw up a comprehensive treatment plan, perform dental prosthetics and evaluate the results obtained. The purpose of the work: to propose a fast and effective method for the comprehensive assessment of an artificial tooth crown, which would have practical application by dentists, would not require significant efforts to interpret the results, and also took into account the general subjective assessment of the patient's quality of life. We have created a web page on the Internet where the proposed two-stage questionnaire is posted. The following technologies and libraries were used to implement the project: HTML5: The main markup language for creating the structure of a web page, including a table with evaluation parameters. CSS: A style language used for the visual design of a table and other elements of a web page to provide a user-friendly and intuitive interface for users. JavaScript: A scripting programming language used to implement the logic of calculating the W coefficient and dynamically displaying the results on the page. The first part is an assessment of artificial crowns according to the method of patent No. 2619386 From the Russian Federation, IPC A61B 10/00 [3], supplemented by an assessment of galvanosis phenomena. The second part is presented by the standardized questionnaire OHIP-14RU [1]. The proposed technique allows for a quick, effective, comprehensive and unified assessment of artificial crowns and their impact on the comfort of the patient's quality of life. Conclusions. This work is aimed at improving the results of comprehensive orthopedic treatment and rehabilitation of patients. The technique allows for a comprehensive assessment, is fast and effective, and is suitable for direct use at a clinical appointment and in research activities in the field of medicine.

Safety and Efficacy of Minimally Invasive Sacrospinous Ligament Fixation for Apical Pelvic Organ Prolapse in Older Women.

Background: This study aimed to evaluate the safety and efficacy of minimally invasive sacrospinous ligament (SSL) fixation of apical pelvic organ prolapse (POP) in older patients compared to younger patients. Methods: A cohort of 271 older (≥65 years) patients (mean age 71.8 ± 5.2 years) and 60 younger patients (mean age 47.6 ± 7.1 years) with stage III or IV apical POP who underwent SSL fixation by the EnPlace® device was retrospectively analyzed. The age range of older patients was further divided into early old (65-74 y, N = 209), old (75-84 y, N = 58), and late old (>85 y, N = 4). Patient characteristics, surgical safety, and 6-month postoperative outcomes were compared between the four age groups. Results: Duration of surgery and blood loss were similar among all age groups. Most patients (99.4%) were discharged on the day of surgery or the day after. Subjective patient satisfaction rates were high among all patients. Point C measurements at six months postoperatively were less favorable among the younger patients. Furthermore, four (6.7%) younger patients versus six (2.2%) older patients required surgical repair of recurrent apical POP within the follow-up period. Conclusions: The short-term outcomes of minimally invasive SSL fixation suggest that it is a safe and effective procedure for significant apical POP repair among older patients.

Polyetheretherketone split post and core for restoration of multirooted molar with insufficient dental tissue remnants by digital techniques: a case report and 3-year follow up

BackgroundMulti-rooted teeth with extensive dental defects often face challenges in stability and biomechanical failure. High-performance polymer PEEK materials, with properties closer to dentin, show promise in reducing stress concentration and preserving tooth structure. This report aimed to explore the use of a highly retentive polyetheretherketone (PEEK) for manufacturing custom-made split post and core for the restoration of grossly destroyed endodontically treated molars.Clinical considerationsA 40-year-old female patient presented with complaints of loss of tooth substance in the posterior mandibular tooth. This case involved the digital design and fabrication of PEEK split post and core to restore multirooted molar with insufficient dental tissue remnants. The restorations were evaluated over a 3-year follow-up using the World Federation criteria (FDI). The restoration was clinically evaluated through intraoral examination, radiographic assessment, and subjective patient satisfaction, and was deemed clinically good according to FDI criteria.ConclusionThe outstanding mechanical properties of PEEK, coupled with the structure of the split post, provide an effective treatment option for weakened multirooted teeth. Simultaneously, the restoration configuration effectively addressed the challenge of varying postinsertion directions, and the interlocking mechanism between the primary and auxiliary posts enhanced the stability of the post and core.

An interdisciplinary integrated specialized one-stop outpatient clinic for idiopathic intracranial hypertension – a comprehensive assessment of patient satisfaction

BackgroundManagement of idiopathic intracranial hypertension (IIH) is complex requiring contributions from multiple specialized disciplines. In practice, this creates considerable organizational and communicational challenges. To meet those challenges, we established an interdisciplinary integrated outpatient clinic for IIH with a central coordination and a one-stop concept. Here, we aimed to evaluate effects of this one-stop concept on subjective patient satisfaction and economic outcome in patients with IIH.MethodsIn a retrospective cohort study, we compared the one-stop era with integrated care (IC, 1-JUL-2021 to 31-DEC-2022) to a reference group receiving standard care (SC, 1-JUL-2018 to 31-DEC-2019) regarding subjective patient satisfaction (assessed by the Vienna Patient Inventory). Multivariable binary linear regression models were used to adjust for confounders.ResultsBaseline characteristics of the IC group (n = 85) and SC group (n = 81) were comparable (female: 90.6% vs. 90.1%; mean age: 33.6 vs. 32.8 years, educational level: ≥9 years of education 60.0% vs. 59.3%; located in Vienna 75.3% vs. 76.5%). Compared to SC, management within IC concept was associated with statistically significantly higher subjective patient satisfaction (beta = 0.93; p < 0.001) with the strongest effects observed in satisfaction with treatment accessibility and availability (beta = 2.05; p < 0.001). Subgroup analyses of patients with migration background and language barrier consistently indicated stronger effects of IC in these groups.ConclusionsInterdisciplinary integrated management of IIH statistically significantly and clinically meaningfully improves patient satisfaction – particularly in socioeconomically underprivileged patient groups. Providing structured central coordination to facilitate and improve access to interdisciplinary management provides means to further improve outcome.

Clinical examples of correct orientation of a toric intraocular lens in patients with postkeratotomic corneal ectasia

BACKGROUND: Surgical treatment of cataract in patients with postkeratotomic corneal ectasia has various features. First, difficulties arise when calculating the optical strength of an intraocular lens and its cylindrical component and determining the location of the main axes of astigmatism for toric intraocular lens implantation. Additionally, not all modern keratotopography installations are able to accurately determine the refractive power of the cornea in such patients owing to pronounced irregular astigmatism and a large difference in keratometric parameters in the main meridians. CLINICAL CASES DESCRIPTION: Two clinical cases of surgical treatment of cataract in combination with postkeratotomic keratectasia are presented. Patients underwent a standard preoperative ophthalmological examination. TMS-4 Tomey keratotopograph was used to accurately determine the refractive power of the cornea. The optical power of toric intraocular lens were calculated using the Holladay 2 formula with amendments for radial keratotomy and the Johnson Johnson VISIC online calculator. SN6AT9 intraocular lens (Alcon) and a Tecnis ZCT800 toric intraocular lens (Johnson Johnson) were implanted in patients. The orientation of the position of the cylinder axis of toric intraocular lens was performed perpendicular to the most flattened meridian, corresponding to the position of the keratectasia zone, determined by the most expanded keratotomy scar. Before surgery, the best corrected visual acuity of patient M was OD=0.2, OS=0.4 and that of patient K was OD=0.4, OS=0.2. After surgery, the best corrected visual acuity of patient M was OD=0.8, OS=0.8 and that of patient K was OD=0.8, OS=0.7. CONCLUSION: This study aimed to familiarize practicing ophthalmologists, clinical residents, and postgraduates with a possible treatment option for cataracts by phacoemulsification with implantation of a toric intraocular lens in patients with postkeratotomic keratectasia. The resulting high visual acuity and subjective satisfaction of patients indicate the accuracy of chosen treatment tactics. A reliable visual guide for choosing the cylinder axis is the meridian of the greatest degree of keratectasia (cornea flattening), which is determined by the maximally expanded keratotomy scar position. The intraocular lens cylinder axis is oriented perpendicular to the keratectasia meridian. Ultrasound phacoemulsification of cataract with implantation of a toric intraocular lens is an effective method for correcting induced ametropia after radial keratotomy against the background of postkeratotomy keratectasia with high astigmatism.

Dorsal Metatarsal Closed Wedge Osteotomy in the Treatment of Freiberg's Disease: A Prospective Observational Study.

The aim of this study was to prospectively evaluate the clinical and radiological results of dorsal metatarsal closed wedge osteotomy and headless screw fixation in the surgical treatment of Freiberg's disease.Thirty-four patients who were treated with dorsal metatarsal closed wedge osteotomy (DMCWO) for Freiberg's disease between February 2018 and March 2022 were included in the study. Patients were staged according to the classification system described by Smillie. Clinical outcomes were evaluated using the American Orthopedic Foot and Ankle Society's (AOFAS) lesser metatarsophalangeal-interphalangeal scale, the visual analog scale (VAS), the range of motion (ROM) of the metatarsophalangeal (MTP) joint, and a subjective patient satisfaction questionnaire. For radiological evaluation, the amount of preoperative shortening of the involved metatarsal, the amount of metatarsal shortening developed after osteotomy, and radiological recovery times were recorded.Thirty-two (94.1%) of the patients were female, and two (5.9%) were male. The average postoperative follow-up period for patients was 33.7 months (range: 24 months to 41 months). The mean AOFAS scores increased from 53.24 to 86.26 (p<0.01). The mean VAS scores decreased from 8.59 to 1.79, and it was observed that the patients' pain improved significantly (p<0.01). The mean ROM of the MTP joint increased from 48.76 degrees to 70.76 degrees (p<0.01). An average of 2.5mm (range 1mm to 4.1mm) of shortening of the metatarsal length developed postoperatively (p<0.01). Arthrosis developed in 1 case (2.9%), and transfer metatarsalgia developed in 2 cases (5.8%).DMCWO is an effective treatment for both the early and advanced stages of symptomatic Freiberg's disease, leading to high patient satisfaction.

Scleral Lenses for Managing Dry Eye Disease in the Absence of Corneal Irregularities: What Is the Current Evidence?

Scleral lenses (SLs) are large-diameter rigid contact lenses that are a mainstay treatment for eyes with corneal irregularities. In recent years, there has been increased interest in the role of managing dry eye disease (DED) with SLs, as many patients with DED have reported symptomatic relief with SL wear. The role of SLs for DED management when there are associated corneal irregularities is supported by individual case reports and studies. This has prompted practitioners to begin advocating using SLs in DED cases, even in the absence of associated corneal irregularities and other ocular surface diseases (OSDs). There have also been discussions on potentially placing SLs earlier in the treatment hierarchy of DED, where it currently sits at a more advanced level of intervention (Step 3) in the TFOS DEWS II Report. This review will present the currently available, albeit sparse, evidence that supports and suggests this practice, as well as ancillary evidence supporting the purported benefits of SL wear in DED. The advantages of SL wear, such as corneal healing, absence of tear evaporation and contact lens dehydration, and improved visual acuity with associated increased wear comfort, and how this will benefit DED patients will be explored. Conversely, the challenges associated with fitting SLs in DED patients, including increased midday fogging, poor wettability, and subjective patient satisfaction, will also be presented, as well as a discussion on the key considerations for SL fitting in this population. Overall, while more research is needed to support the use of SLs in DED patients without associated corneal irregularities and other forms of OSD, the use of these lenses may prove to have a potentially wider role given their reported ancillary benefits in these populations.

A Comparative Study of Correction of Caudal Septal Deviations.

There are multiple surgical approaches for the correction of caudal septal deviation. To compare the surgical outcomes of the widely used techniques of correction of caudal septal deviation. In a prospective study done over a period of 3 years, 36 patients with caudal septal deviation were selected and randomly divided into 3 groups of 12 each who underwent surgery by the following techniques: Group A - Swinging Door technique. Group B- Tongue-in-groove technique. Group C- The cutting and suture technique with unilateral bony batten grafting. The preoperative and postoperative (at 6 months) NOSE score, anterior rhinoscopy and subjective assessment were used to measure surgical outcomes and the techniques were compared. Out of the 36 patients, the mean NOSE score preoperatively and postoperatively were as follows. For Group A- 72.5 and 23.33. For Group B- 73.75 and 19.17. For Group C- 72 and 22. A significant improvement of mean 49.17, 54.58 and 50.00 with p-value of < 0.05 respectively. Anterior rhinoscopy done at 6 months postoperatively showed that 30 patients (83%) had a straight septum while 6 patients (17%) had some residual deviation. Subjective patient satisfaction was "much improved" in 17 (47.2%) patients, and "improved" in 19 (52.8%) patients. Four patients had postoperative synechia which were managed conservatively. Surgical correction of caudal septal deviation resulted in significant improvements in nasal airway. The tongue-in -groove technique was found to be the most effective among the three.

Platelet-Rich Plasma Injections in Chronic Lateral Ankle Instability: A Case Series.

The platelet-rich plasma (PRP) approach may be an effective treatment for joint and cartilage pathologies. However, the rationale for its effectiveness on joint instability is limited. This study aimed to assess the safety and effectiveness of PRP injections in patients with chronic lateral ankle instability (CLAI). This retrospective study was performed at a single-center outpatient clinic between January 2015 and February 2023 and included pre-intervention assessment and short-term follow-up. Patients were excluded if they had received previous surgical treatment or had constitutional hyperlaxity, systemic diseases, or grade II or III osteoarthritis. The clinical and functional evaluation consisted of the Karlsson score, the Cumberland Ankle Instability Tool (CAIT), Good's grading system, the patient's subjective satisfaction level, and the time required to return to exercise. The entire PRP therapy regime consisted of three PRP administrations at 7-day intervals and follow-up appointments. PRP was administered both intraarticularly and into talofibular ligaments. A total of 47 consecutive patients with CLAI were included, 11 were female (23.4%), with a mean age at intervention of 31.19 ± 9.74 years. A statistically significant improvement was found in the CAIT and Karlsson scores at 3 months (27.74 ± 1.68 and 96.45 ± 4.28, respectively) relative to the pre-intervention status (10.26 ± 4.33 and 42.26 ± 14.9, respectively, p < 0.000). The mean follow-up of patients with CLAI was 17.94 ± 3.25 weeks. This study represents successful short-term functional and clinical outcomes in patients with CLAI after PRP treatment, with no adverse effects. It demonstrates the feasibility of a randomized controlled trial to further assess this therapy.

Could the different surgical goals of fusion and non-fusion also be achieved in combination within the same patient? Clinical and radiological outcome of hybrid cervical spine surgery.

Hybrid cervical spine surgery (HS) is a novel surgical strategy wherein an artificial disc replacement is done with a cervical fusion nearby with a stand-alone titanium cage to combine the advantages in both procedures. The aim of this study was to evaluate interactions of these devices within the same patient, and to analyze, if the different goal of each implant is accomplished. Thirty-six patients were treated surgically within a non-randomized retrospective study framework with HS. Patients were examined preoperatively followed by clinical and radiological examination at least one year postoperative. Clinical outcome was detected with NDI, VAS arm/neck, pain self-assessment questionnaires and subjective patient satisfaction. Radiological assessments included RoM, segmental lordosis, cervical lordosis of C2-C7, subsidence, ap-migration and heterotopic ossifications (HO) at the cTDR levels. Statistically significant improvement of all clinical scores was observed (NDI 37.5 to 5.76; VASarm 6.41 to 0.69; VASneck 6.78 to 1.48). Adequate RoM was achieved at cTDR levels. RoM in the ACDF levels was reduced statistically significant (p < 0.001), and solid fusion (> 2°) was achieved in all evaluated fusion level. Global lordosis (C2-C7) increased statistically significant (2.4° to 8.1°). Subsidence and HO at the cTDR levels did not occur. HS results in preservation of the segmental motion in the cTDR and fast and solid fusion in the cage cohort simultaneously. Patient safety was proven. In carefully selected cases, HS is a safe and viable treatment option by choosing the right "philosophy" level per level.

Liposuction-Only Breast Reduction: A Systematic Review of Outcomes.

Over the past few decades, there have been multiple reports of liposuction assisted breast reduction. This technique appeals to patients due to the limited scars and complication profile, compared to traditional reduction mammaplasty techniques. We aimed to systematically review the literature, to elucidate the outcomes and safety of liposuction-only breast reduction. A systematic review was performed using the Ovid (Medline/PubMed) database, in accordance with the PRISMA checklist. In total 7 articles were included within this systematic review. A total of 652 patients were included. Liposuction-only breast reduction appears to lead to improvements in subjective outcome measures, patient satisfaction, and objective outcomes such as moderate breast volume reduction and reduction in breast ptosis. Overall, the procedure had a low complication profile. Liposuction did not preclude further surgery. No evidence of malignancy or difficulty in future breast cancer screening was noted. Macromastia leads to a considerable health burden, especially in health-related costs. From the current evidence base, liposuction-only breast reduction appears to be a safe and effective procedure, especially in patients requiring a mild-moderate breast volume reduction and mild ptosis correction. More research is required, with standardised subjective and objective outcome measures, and longer follow-up periods to confirm the effectiveness and safety of this technique.

Evaluation of Clinical Results of Implantation of Toric Intraocular Lenses Including their Rotational Stability.

The aim of the study was to evaluate the clinical results of the implantation of the toric intraocular lens Acrysof IQ Toric SN6AT3_8(Alcon Laboratories, Inc., Fort Worth, TX, USA), including an evaluation of its rotational stability. 30 eyes of 16 patients (4 males, 12 females; mean age 68 years) with regular corneal astigmatism ranging from -1.5 to -4.0 Dcyl were included in this retrospective study. All the patients underwent uncomplicated cataract surgery with the implantation of a toric intraocular lens (TIOL) at the Department of Ophthalmology of the Faculty of Medicine and Dentistry of Palacký University in Olomouc and University Hospital Olomouc during the course of 2020. Follow-up examinations were performed 3-6 months after cataract surgery. We monitored the resulting uncorrected distance visual acuity (UDVA), postoperative refraction, rotational stability of the implanted lens and subjective patient satisfaction. mean preoperative corneal astigmatism was -2.41 ±0.67 Dcyl. UDVA improved from a mean value of 0.45 ±0.25 (expressed in decimal Snellen optotype values) to 0.91 ±0.16. The spherical equivalent value of 0.41 ±2.92 improved to -0.11 ±0.27 postoperatively. The mean deviation from the planned axis was 4.87 ±4.75. Subjective satisfaction was rated by patients on a scale of 1-5, with a mean score of 1.5. TIOL implantation is a safe and effective solution for patients with corneal astigmatism and cataract. Our results demonstrate improved UDVA, rotational stability of the TIOL and subjective patient satisfaction with the outcome of the surgery.

Meralgia Paresthetica-An Approach Specific Neurological Complication in Patients Undergoing DAA Total Hip Replacement: Anatomical and Clinical Considerations.

Introduction: Mini-invasive surgical (MIS) approaches to total hip replacement (THR) are becoming more popular and increasingly adapted into practice. THR via the direct anterior approach (MIS DAA) has become a rather controversial topic in hip arthroplasty literature in the last decades. Our retrospective observational study focuses on the prevalence of one approach-specific complication-lateral femoral cutaneous nerve (LFCN) iatrogenic lesion-and tries to clarify the possible pathogenesis of this injury. Methods: This is a retrospective single-cohort observational single-center and single-surgeon study. Our patient records were searched for the period from 2015 to 2017-after a safe period of time after the learning curve for MIS DAA. All intra- and post-operative lesions of the LFCN were recorded. Lesion of the LFCN was confirmed by a neurological examination. Minimum patient follow-up was 2 years. Results: This study involved 417 patients undergoing single-side THR via MIS DAA. Patients were examined on follow-up visits at 6 weeks, 6 months, 1 year, and 2 years after surgery. There were 17 cases of LCFN injury at the 6 weeks early follow-up visit (4.1%). All cases of clinically presenting LFCN injury resolved at the 2-year follow-up ad integrum. Discussion: Possible explanations of such neurological complications are direct iatrogenic injury, vigorous traction, hyperextension, or extreme external rotation of the operated limb. Use of a traction table or concomitant spinal pathology and deformity also play a role. Prevention involves stepwise adaptation of the approach during the learning curve period by attending cadaver lab courses, rational use of traction and hyperextension, and careful surgical technique in the superficial and deep fascial layers. Dynamometers could be used to visualise the limits of manipulation of the operated limb. Conclusions: Neurological complications are not as rare but questionably significant in patients undergoing THR via the DAA. Incidental finding of LFCN injury has no effect on the functional outcome of the artificial joint. It can lead to lower subjective satisfaction of patients with the operation, which can be avoided with careful education and management of expectations of the patients.

Timing of Surgery for Proximal Humeral Fracture Treated with Shoulder Hemiarthroplasty, Best Results with Surgery Within 2 Weeks

BackgroundPreoperative delay may affect the outcome of proximal humerus fractures treated with shoulder hemiarthroplasty. There is currently no consensus for the recommended preoperative time interval. The aim was to examine how the time to surgery with shoulder hemiarthroplasty after a proximal humerus fracture affected the patient-reported outcome.Methods380 patients with proximal humerus fractures treated with shoulder hemiarthroplasty recorded from the Swedish Shoulder Arthroplasty Registry were included. Three self-reporting outcome instruments were used at follow-up after 1–5 years: a shoulder-specific score, the Western Ontario Osteoarthritis of the Shoulder index (WOOS), the EuroQol-5 Dimension index (EQ-5D), and subjective patient satisfaction assessment.ResultsThe preoperative delay had a negative impact on the WOOS, EQ-5D, and patient satisfaction level (p < 0.01). The best result, measured with WOOS at a minimum 1-year follow-up, was found when surgery was performed 6–10 days after the reported date of fracture. WOOS% 8–14 days was 69.4% (± 24.2). A delay of more than 10 days was shown to be correlated with poorer outcomes. WOOS% 15–60 days was 55.8% (± 25.0) and continued to decrease.ConclusionThe current recommendation in Sweden to perform shoulder hemiarthroplasty within 2 weeks after sustaining a proximal humerus fracture is considered valid.

Autologous fat grafting and adipose-derived stem cells therapy for acute burns and burn-related scar: A systematic review.

The objective of this study was to analyze all available research on the application of autologous fat grafting (AFG) and adipose-derived stem cells (ADSC) to present evidence-based recommendations, particularly in the clinical treatment of acute burns and burn-related scars. We conducted a systematic search of PubMed, COCHRANE, and EMBASE, as well as a manual search of previous reviews' reference lists up. The risk of bias (RoB) was assessed using RoB 2.0 and ROBINS-I, where appropriate. Six eligible studies were selected (2 randomized clinical trials [RCT], 1 retrospective cohort, and 3 experimental studies) with subjects ranging from 3 to 100. Only one study evaluated the use of AFG for acute burns. Improvements in wound healing, vascularization, scar characteristics, and tissue architecture were generally observed in some studies, supported by molecular markers, while one study reported nonsignificant results. Subjective patient satisfaction was reported to have improved. Functional outcomes improvement in the treated regions was minimal. However, study heterogeneity arose mainly from treatment protocols. Cautious results interpretation due to potential bias, especially in selection and confounding domains, and limited clinical trials are important to note. More studies are needed to evaluate. AFG and ADSC hold potential as valuable treatment options for burn-related scars, supported by a body of evidence, but further well-designed RCT are needed. The efficacy of acute burn settings is yet to be further evaluated since evidence is limited.

Angle Kappa Influence on Multifocal IOL Outcomes

Purpose: To characterize angle kappa and study the relationship between preoperative angle kappa and postoperative refractive accuracy, visual outcomes, and patient satisfaction in a large population of eyes with multifocal intraocular lens (MIOL) implantation. Methods: A comprehensive electronic medical record chart review of 26,470 consecutive eyes that underwent immediate sequential bilateral cataract or refractive lens exchange with MIOLs was conducted. The primary outcome measures were postoperative monocular uncorrected distance visual acuity (UDVA), manifest refraction sphere and cylinder, spherical equivalent (SEQ), defocus equivalent (DEQ), subjective quality of vision at near, intermediate, and distance, and the likelihood of recommending the procedure. Relationships between preoperative angle kappa and postoperative outcomes were assessed with Pearson correlations. Results: Angle kappa followed a right-skewed normal distribution ( R 2 = 0.99) with a mean ± standard deviation of 0.64 ± 0.27 mm. No clinically meaningful relationship was found between preoperative angle kappa and postoperative sphere, cylinder, SEQ, and DEQ, all with R 2 ⩽ 0.0005. Similarly, there was no clinically meaningful relationship between preoperative angle kappa and postoperative UDVA ( R 2 = 0.001), postoperative satisfaction for near, intermediate, and distance vision (all R 2 ⩽ 0.0023), or for recommending the MIOL surgery to friends and relatives ( R 2 = 0.0000). Conclusions: Preoperative angle kappa does not have a predictive clinical impact on postoperative MIOL visual outcomes, refractive accuracy, or subjective patient satisfaction. Angle kappa as a single variable cannot be used to determine MIOL candidacy. [ J Refract Surg . 2023;39(12):840–849.]

Percutaneous plate fixation of displaced proximal humerus fractures: Do minimally invasive techniques improve outcomes and reduce complications?

ObjectiveThe aim of this study was to analyze the outcomes and complications of minimally invasive plate osteosynthesis (MIPO) for displaced proximal humerus fractures and elucidate if the percutaneous technique reduces the rate of avascular necrosis (AVN) without jeopardizing fracture reduction. Material and methods118 patients with a displaced proximal humerus fracture were treated with a polyaxial locking-plate through a standardized percutaneous approach. 73 % were women and mean age was 63 years (18–89) with an average follow-up of 51 months (12–256). There were 32 two-part fractures (27 %), 57 three-part fractures (48 %) and 24 four-part fractures (25 %). Shoulder function at the last follow-up, including ROM and ability to perform daily living activities, was objectively evaluated with an adjusted Constant Score (CS). Subjective patient satisfaction was rated with an Visual Analogic Scale from 0 to 10 and the degree of residual pain with a Verbal Rating Scale (VRS). Radiographic analysis at the most recent follow-up evaluated the presence of AVN, degree of residual medial calcar displacement, and the cervicodiaphiseal angle. ResultsForty patients (34 %) had a complication, 25 of them (21 %) requiring further surgery. ROM at the last follow-up was 131° of elevation (40°-180°), 38° of external rotation (SD: 17.7) and internal rotation to L3. Average adjusted Constant Score was 68 (SD: 17.76). Twenty-one patients (18 %) complained of shoulder pain (14 moderate and 7 severe) and seven were not satisfied. Radiographically, 29 patients (25 %) had varus malunion and 17 patients (14 %) showed some degree of AVN. Patients with varus malunion (CS 64.3 versus 69.8, p = 0.16) and AVN (CS 56.9 versus 70.4, p = 0.005) had lower CS. The presence of a varus malunion was directly related to the degree of initial medial calcar displacement (p = 0.001) and deficient calcar reduction at surgery (p = 0.004). AVN was statistically more prevalent when the medial calcar was inadequately reduced (p = 0.01). ConclusionsMIPO surgery for proximal humerus fractures through an anterolateral approach does not reduce the rate of mechanical complications or AVN compared with standard ORIF techniques. Moreover, percutaneous plating may preclude adequate medial calcar reduction, leading to humeral head malunion and a worse clinical outcome.

Basal osteotomy of the first metacarpal using patient-specific guides and instrumentation: biomechanical and 3D CT-based analysis

IntroductionThe aim of this study was to investigate the radiological outcomes of proximal closing metacarpal extension osteotomies using patient-specific guides and instruments (PSI) in early-stage trapeziometacarpal osteoarthritis to gain further insight into the joint loading surface and the benefits of the procedure.MethodsIn a prospective observational study, nine patients were included between 11/2020 and 12/2021, undergoing a total of ten proximal metacarpal extension osteotomies for basal thumb osteoarthritis. Computer-assisted surgical planning was performed using computed tomography (CT) and three-dimensional (3D) segmentation, allowing the fabrication of 3D-printed PSIs for surgical treatment. Inclusion criteria were a 1-year follow-up by CT to assess postoperative correction of the positional shift of the first metacarpal (MC1) and the location of peak loads compared with the preoperative situation.ResultsRadiographic analysis of the peak loading zone revealed a mean displacement on the articular surface of the trapezius of 0.4 mm ± 1.4 mm to radial and 0.1 mm ± 1.2 mm to palmar, and on the articular surface of the MC1 of 0.4 mm ± 1.4 mm to radial and 0.1 mm ± 1.2 mm to dorsal.ConclusionThere were trends indicating that a flatter pressure distribution and a dorsal shift of the peak loading zone may contribute to an improvement in subjective pain and patient satisfaction associated with this surgical procedure. The non-significant radiological results and the minor dorsal-radial shifts in our small study group limit a firm conclusion.Level of evidenceIII.

Comparison Between Clinical, Radiological and Functional Outcome of Arthroereisis vs Corrective Osteotomies for Correction of Symptomatic Flexible Pes Planovalgus in Adolescents

Category: Hindfoot; Midfoot/Forefoot Introduction/Purpose: Flexible pes planovalgus is a common deformity in young adolescents. It can interfere with daily activities and athletic participation. If conservative treatment fails, operative intervention is justified. Operative interventions include lateral column lengthening alone, multiple osteotomies (medial translation calcaneal osteotomy, lateral column lengthening, and Cotton osteotomies), and arthroereisis. All these options can be combined with gastrocnemius recession, excision of accessory navicular, or other soft tissue procedures. Arthroereisis is a highly controversial procedure with a great debate regarding indications, safety and clinical outcome. The literature comparing corrective osteotomies to arthroereisis in young adolescents is deficient and non conclusive. This study was done to compare the clinical and radiological outcome of multiple corrective osteotomies to arthroereisis in young adolescents. Methods: This is a case control prospective study that included 40 feet (20 feet in each group) in 25 patients with flexible pes planovalgus deformity in patients aged 10 to 13 years, after failure of conservative treatment. Exclusion criteria included generalised ligamentous laxity, neurogenic disorders, and rigid deformity. Cases with severe talonavicular uncoverage (angle more than 40 degrees) were excluded as this might be a contraindication to arthroereisis. Group 1 underwent correction by multiple osteotomies (medial translation calcaneal osteotomy, lateral column lengthening, and Cotton osteotomies) and group 2 underwent arthroereisis using a conical titanium subtalar spacer. Gastrocnemius recession and resection of painful accessory navicular were done if indicated in both groups. Clinical outcome was assessed using AOFAS, FAAM scores and subjective patient satisfaction. Radiological assessment included lateral talocalcaneal angle, anteroposterior and lateral talus first metatarsal angle, talonavicular coverage angle, and calcaneal pitch angle. Results: The mean follow up in group 1 was 29 months compared to 25 months in group 2. Preoperatively, there was no statistically significant difference between the two groups regarding patient demographics, clinical scores, or radiological measurements. Clinically, 18 patients were satisfied in group 1, compared to 17 patients in group 2. The mean AOFAS score improved significantly from 73 (62-90) to 91(73-100) in group 1 and from 73 (62-90) to 89 (73-100) in group 2. FAAM score improved significantly from 76% (68-87) to 95.75% (74-100) in group 1, and from 73% (62-86) to 91% (71-98) in group 2. The difference between the two groups was not statistically significant. All radiological measurements improved significantly in both groups without a statistically significant difference between the two groups. Conclusion: Clinical and radiological outcome of arthroereisis is comparable to corrective osteotomies in young adolescents with symptomatic pes planovalgus deformity and can be a valid option in management of these cases, but long term follow up is needed. Also, consensus regarding the perfect age, implant removal, and the degree of talonavicular uncoverage that can be corrected by arthroereisis need further studies.

Safety and Efficiency of Low-Dose Spinal Analgesia Compared to Epidural Analgesia in Treatment of Pain during Labour: A Case Control Study.

The epidural catheter for analgesia has been used for decades and has become the gold standard in pain therapy for pregnant women in labour. However, procedural parameters such as time to pain relief and duration to implementation pose hurdles for patients shortly before delivery. Low-dose spinal analgesia (LDSA) is an alternative procedure that was investigated in the study with regard to patient satisfaction and complication rates compared to epidural catheter. In a retrospective monocentric study, a total of 242 patients receiving low-dose spinal analgesia or epidural catheters were evaluated using propensity score matching. Subjective patient satisfaction as well as complication rates were primarily analysed. We hypothesise that LDSA is a safe procedure and provides a similar level of satisfaction compared with the epidural catheter. For this purpose, both procedures were performed according to in-house standards and the patients were interviewed afterwards. Patients who required surgical delivery were excluded to prevent bias. The LDSA was rated on average as very good [1.09 ± 0.311 vs. 1.07 ± 0.431] in terms of satisfaction by the patients compared to the epidural catheter without showing a significant difference (p = 0.653). Complications were in the low single-digit non-significant range for both procedures [6 (5%) vs. 7 (6%); p = 0.776]. The evaluation showed more perineal tears I° and II° in the low-dose spinal analgesia group [I°: 28 (23%) vs. 3 (2%); p < 0.001-II°: 30 (25%) vs. 2 (2%); p < 0.001]. Neonatal parameters differed significantly only in umbilical cord base excess and umbilical cord venous pH [-5.40 vs. -6.40; p = 0.005]. LDSA represents a low complication procedure for patients at the end of labour with a high satisfaction level. With the LDSA in the repertoire of pain relief during childbirth, it is possible to also achieve pain reduction for women with deliveries of high velocity without compromising patient satisfaction or perinatal morbidity.
