Atraumatic Sport-Related Medial Sesamoid Pain: Conservative Treatment Outcome and Magnetic Resonance Imaging Features.

This study aimed to evaluate the effectiveness of conservative treatment in selected patients with atraumatic medial sesamoid pain (MSP) that developed during sports activities. The secondary aim was to determine the detailed underlying pathology in patients who did not respond to conservative treatment using magnetic resonance imaging (MRI). From March 2015 to August 2022, we prospectively followed 27 patients who presented to our outpatient clinic with atraumatic sports-related MSP. The conservative treatment protocol for MSP included the use of oral analgesics, activity restriction, insole modification, local corticosteroid injections, and boot walker application with crutches. MRI was performed for all patients who experienced persistent pain despite the completion of conservative treatment. After the completion of the conservative treatment protocol, 48.1% of the patients reported a reduction in pain. Patients with younger age at pain onset (p = 0.001), higher body mass index (p = 0.001), and a bipartite medial sesamoid (p = 0.010) were more likely to experience persistent pain after conservative treatment. The type of sports activity was also a factor since running- and dancing-related MSP tended to respond better to conservative treatment compared to MSP originating from golf, futsal, and weightlifting with squatting. On MRI, 42.8% of patients showed no specific abnormal findings, with signal changes in soft tissues such as the subcutaneous fat and bursa being the most common, followed by intraosseous signal changes of the medial sesamoid bone and chondral or subchondral lesions of the medial sesamoid metatarsal joint (28.6% each). Conservative treatment was successful in less than half of the patients who experienced MSP due to sports activity. Practitioners should be aware of the numerous possible causes of conservative treatment failure, such as bursitis, medial sesamoiditis, stress fracture, or chondral lesions between the medial sesamoid and metatarsal. MRI evaluation may be helpful in MSP patients who do not respond to conservative treatment.

Minimally Invasive Posterior Spinal Nonfusion Surgery in Patients With Adolescent Idiopathic Scoliosis Using a Bipolar One-Way Self-Expanding Rod System: Protocol for a Single-Center Clinical Cohort Study.

The current surgical treatment for patients diagnosed with progressive and severe adolescent idiopathic scoliosis (AIS) consists of the correction of the spinal curvature, followed by posterior spinal fusion (PSF). However, research has uncovered short- and long-term complications of posterior spinal fusion in patients with AIS. Minimally invasive growing rod techniques have successfully been used to treat patients with early-onset scoliosis and neuromuscular scoliosis. It may be questioned if minimally invasive posterior spinal nonfusion (PSnF) surgery with bipolar instrumentation can be used for the treatment of AIS. This study will be performed to monitor the efficacy and safety of PSnF surgery by using a commercially available Conformité Européenne-certified spinal implant consisting of bilateral bipolar one-way self-expanding rods (OWSER) for the treatment of patients diagnosed with AIS. In 14 selected patients with AIS with Lenke 1-6 curves, minimally invasive PSnF surgery with the OWSER system is performed after the failure of conservative treatment (curve progression of >5° within 1 year). The patients are over 7 years of age, with a major Cobb angle of ≥30°, sufficient flexibility, and a Risser stage of ≤2. Patients will be followed over time, according to the standard medical care. Efficacy will be measured using radiological and patient satisfaction assessments and safety will be determined by the amount of perioperative complications. Patient inclusion started on November 17, 2021 and we hope to finalize patient inclusion by the beginning of 2025. The first results will be expected by the beginning of 2024. Minimally invasive PSnF in patients with AIS is presented as a less invasive surgical technique that prevents the progression of the scoliotic curve and that allows minor posture correction of coronal imbalance. This will be the first study to examine whether the PSnF bipolar OWSER instrumentation will be the next generation of surgical instrumentation in AIS.

Effect of pelvic floor status on the outcome of pelvic organ prolapse surgery.

Pelvic organ prolapse (POP) is a common diagnosis with an incidence in the population of up to 50%. POP causes restrictions in everyday life and reduces patients' quality of life. Therapy is either conservative in the form of physiotherapy or the use of different types of pessaries, possibly. in case of inappropriateness or failure of conservative treatment, an operative solution is chosen. Avulsion injury of the levator ani muscle (MLA) is a strong factor in the development of POP. Some patients undergo repeated surgeries for POP, negatively impacting their quality of life. Studies show that the stage of POP and avulsion injury is associated with an increased risk of recurrence after index prolapse surgery. Ultrasound diagnosis of MLA injuries might help in predicting the risk of recurrence. Assessment of pelvic floor function is crucial for the success of surgical management of POP.

Intrarectal injections of botulinum toxin versus placebo for the treatment of urge faecal incontinence in adults (FI-Toxin): a double-blind, multicentre, randomised, controlled phase 3 study

Non-randomised studies assessing intrarectal botulinum toxin type A (BoNTA) injections for faecal incontinence are promising. We aimed to evaluate the efficacy of BoNTA for the treatment of faecal incontinence in a randomised study. In this randomised, double-blind, placebo-controlled study, we included adult patients who had at least one urgency or faecal incontinence episode per week for at least 3 months and who had experienced a failure of conservative or surgical treatment from eight French specialist hospital units with the skills to manage patients with faecal incontinence. Patients were randomly assigned (1:1) by a central web form to receive intrarectal submucosal injections of either 200 units of BoNTA (Botox; Allergan, Irvine, CA, USA; BoNTA group) or an equivalent volume of saline (placebo group), stratified by Cleveland Clinic Severity scores (CCS score; ≥12 or <12). Patients, investigators, study site staff, and sponsor personnel were masked to treatment allocation up to the 6-month visit. The primary endpoint was the number of episodes of faecal incontinence and urgency per day assessed using 21-day patient bowel diaries 3 months after the treatment. The primary analysis was performed using a modified intention-to-treat (mITT) approach (ie, in all the randomised patients who had received a treatment) with adjustment for baseline faecal incontinence and urgency episodes. After the final data collection at 6 months after injections, patients were unmasked and offered the BoNTA treatment if they were in the placebo group (rescue therapy) without masking, with an additional 6 months of safety follow-up. This trial is registered with ClinicalTrials.gov, number NCT02414425. Between Nov 25, 2015, and Nov 25, 2020, we randomly assigned 200 patients to receive either BoNTA (n=100) or placebo (n=100) injections. Due to withdrawals before the injections, 96 patients were included in the BoNTA group and 95 patients were included in the placebo group (mITT analysis). The mean number of faecal incontinence and urgency episodes per day in the BoNTA group decreased from 1·9 (SD 2·2) at baseline to 0·8 (1·8) at 3 months after the injections, and from 1·4 (1·1) to 1·0 (1·0) in the placebo group, with a baseline-adjusted mean group difference at 3 months estimated at -0·51 (95% CI -0·80 to -0·21, p=0·0008). No serious treatment-related adverse events were reported in the trial. The most frequently reported non-serious adverse event (treatment related or not) following the BoNTA or placebo injections was constipation (reported in 68 [40%] of 169 patients who received the BoNTA injections and 38 [40%] of 95 patients who received placebo injections). BoNTA injections are an efficacious treatment for urge faecal incontinence. Further research will define the optimum selection criteria, dose, site of injection, re-injection frequency, and long-term results. General Direction of Healthcare (French Ministry of Health).

Accessory navicular in children.

Accessory navicular (AN) is a developmental variation of the secondary ossification center of the navicular tuberosity. Ten percent of patients with AN will have pain symptoms that affect walking and life. As the AN changes the position of the posterior tibial tendon insertion, children with AN often have posterior tibial tendon function insufficiency and flexible flat foot. Surgical treatment is often required after failure of conservative treatment. This article reviewed the etiology, clinical manifestations, complications, and treatment methods of AN.

The impact of lymphangiograpy on chyle leakage treatment duration after pancreatic surgery.

Chyle leakage (CL) is a common complication in pancreatic surgery. Lymphangiography is a therapeutic option for CL in cases of conservative treatment failure. This study investigated the effect of lymphangiography on the healing time of CL. We retrospectively evaluated 283 patients who underwent pancreatic resection between January 2016 and June 2022. The risk factors for CL and the treatment period were evaluated according to whether or not lymphangiography was performed. Of the 29 patients (10.2%) that had CL, lymphangiography was performed in 6. Malignant disease, the number of harvested lymph nodes, and drain fluid volume on postoperative day 2 were identified as independent risk factors for CL. Lymphangiography was associated with the cumulative healing rate of CL, and patients who underwent lymphangiography had a significantly shorter treatment period. No lymphangiography-related adverse events were observed. Lymphangiography is a feasible and safe treatment option for CL. The CL treatment period after pancreatic surgery was significantly shorter in patients who underwent lymphangiography than in those who did not. Our results suggest that lymphangiography may contribute to early improvement of persistent CL.

Justification of the conservative treatment of intestinal intussusception in children without age and disease duration considerations

Introduction. Since the middle of the last century, the conservative treatment of ileocecal intussusception (ICI) has dominated in children. However, questions on choosing a technique for conservative treatment and indications for surgical treatment remain open.&#x0D; Purpose. To assess the effectiveness of hydroechocolonoscopy (HEC) for ICI in children regardless of their age and disease duration.&#x0D; Material and methods. 160 children with confirmed ICI were enrolled in the study. All children, who had developed uncomplicated ICI for the first time, had HEC regardless of their age and disease duration. Failed hydrostatic disinvagination and disease relapse after HEC were indications for surgical management (laparoscopy, colonoscopy, laparotomy). To evaluate the effectiveness of conservative treatment at different age groups and at different terms of disease duration, two comparable trials were performed: 1 – stratification of patients by age: main group (n=130) - children older than one year, comparison group (n=30) – children younger than one year; 2 – stratification of patients by disease duration: main group (n=107) – more than 12 hours, comparison group (n=53) – up to 12 hours. To assess outcomes, the following parameters were analyzed: HEC effectiveness and complications, incidence of early relapses after HEC, causes of HEC failure and relapses after HEC, frequency and surgical techniques applied for treating ICI.&#x0D; Results. In the groups stratified by age, HEC effectiveness was 95.4% in the main group and 93.3% in the comparison group, p=0.216. Early relapses occurred in 10.3% in the main group and in 3.3% in the comparison group, p=0.128. In the groups stratified by the disease duration, HEC effectiveness was 93.5% in the main group and 98.1% in the comparison group, p=0.204. Early relapses occurred in 10.3% (11) in the main group and in 11.3% (6) of cases in the comparison group, p=0.841. There were no any complications during HEC procedure. Basic reasons for the conservative treatment failure were anatomical ones; for relapses – lymphoid hyperplasia of the abdominal cavity and anatomical reasons. Thus, HEC was effective in 95% of cases; relapses after HEC amounted up to 10.6%. Surgical interventions ( in 15.6%) were started with laparoscopy; laparoscopic disinvagination was effective in 68% of cases. Colonoscopy after successful laparoscopic disinvagination was performed in 5.6%, conversion to laparotomy was in 5% of the total number of observations.&#x0D; Conclusion. HEC is a highly effective and safe option for HEC conservative management in children regardless of child’s age and disease duration. Indications for surgical treatment for uncomplicated ICI are hydrostatic disinvagination failure and disease relapse.

Reverse total shoulder arthroplasty for proximal humerus fractures: Primary or delayed after failed treatment?

BackgroundReverse total shoulder arthroplasty (RTSA) has recently become an option for the treatment of proximal humerus fractures (PHFs) or as a salvage procedure after failure of another treatment. The purpose of this study was to compare primary RTSA with delayed RTSA in the treatment of displaced PHFs. Study design & MethodsA retrospective cohort study was conducted on patients with PHFs who were treated between May 2013 and December 2021 with primary or delayed RTSA after failure of conservative treatment or osteosynthesis. Clinical data were withdrawn from our local computerized database. Complications, active range of motion, as well as the functional outcome were recorded at the end of the follow-up period. Differences between clinical outcomes were analyzed using a logistic regression analysis. ResultsA total of 70 individuals were included in this study (41 primary RTSA and 29 delayed RTSA). The mean of follow-up time was of 112 and 60 months, respectively. There were no differences between groups regarding fracture type according Neer Classification, ASA score or the presence of complications. Q-DASH and Oxford Shoulder scores were significantly better when patients underwent a primary RTSA (49.8 vs 31.4, p = 0.006 and 37.2 vs 27.5, p = 0.004 respectively). In addition, primary RTSA achieved more degrees of flexion and abduction than delayed RTSA (96.8 vs 72.9, p < 0.001 and 94.1 vs 69.3, p < 0.001 respectively). ConclusionPrimary RTSA for PHFs achieved better functional outcomes and a wider range of motion when compared with delayed RTSA. However, primary and delayed RTSA have similar complication and reintervention rates. Level of Clinical Evidence3

Influencing Factors of Massive Hemorrhage and High-Grade Renal Vascular Injury after PCNL: A Retrospective Comparative Study.

Severe hemorrhage after percutaneous nephrolithotomy (PCNL) is a rare but alerting event. In this study, we report the factors affecting massive hemorrhage after PCNL, various levels of vascular damage during renal angiography, and the therapeutic effect of superselective renal artery embolization (SRAE). Patients and Methods. A retrospective analysis was performed on the data of 69 patients with postoperative PCNL hemorrhage who underwent SRAE from January 2010 to March 2021. Inclusion criteria for all cases were failure of conservative treatment for severe renal hemorrhage after surgery and then treatment with SRAE. In addition, 98 patients without significant hemorrhage after PCNL were randomly selected as the control group. All clinical data are confirmed by imaging and laboratory examinations. We performed univariate and multivariate analyses to find risk factors of massive hemorrhage and high-grade renal vascular injury after PCNL. A total of 69 patients underwent angiography, 64 of which received SRAE due to positive hemorrhages detected by angiography. Urinary tract infection (OR (95% CI) = 11.214 (2.804∼44.842)), high blood pressure (OR (95% CI) = 5.686 (1.401∼23.083)), and no hydronephrosis (OR (95% CI) = 0.189 (0.049∼0.724)) are the most important factors leading to massive hemorrhage after PCNL. In patients who need SRAE after hemorrhage, high-grade vascular injury (grade III) is related to advanced age and decreased hemoglobin. During the perioperative period of PCNL, patients with a risk of hypertension, urinary tract infection, and no hydronephrosis should be strengthened to monitor their high risk of postoperative hemorrhage. For patients with postoperative hemorrhage, we can use the patient's age and decreased hemoglobin before and after operation for analysis. In this way, individualized assessment can greatly improve the efficiency of SRAE treatment.

Arthroscopic biceps tenodesis using press-fit bony plug: a case series study.

To assess the feasibility, operative time, clinical outcomes, possible complications, and failure rates of all-through arthroscopic biceps tenodesis using press-fit bony plug technique. This prospective case series study involved 30 skeletally mature patients with long head of biceps pathology (tendinitis after failure of conservative treatment, subluxation, dislocation, or tendon tears). All patients were followed up for 24months at least. Twenty-nine patients regained full shoulder and elbow range of motion; one case suffered from reflex sympathetic dystrophy. There was a significant improvement in the constant, ASES, and VAS scores when comparing the pre-operative and post-operative values. The average biceps strength was 96% compared to the opposite healthy side. No cases were complicated by neuro-vascular deficits or failure of the tenodesis. Press-fit biceps tenodesis is safe and accessible with low economic demands. We recommend this technique to be used more often when addressing patients with long head of biceps pathologies. Registration number: N-1562023. Registration date: June 2022 "Retrospectively registered".

What is the role of hysterectomy in pelvic organ prolapse treatment?

Pelvic organ prolapse (POP) is a condition with an increasing incidence rate, affecting more than 40% of women over 50 years old. There are three levels of pelvic floor support, described by Delancey. The individual impact of each of them leads to the appearance of prolapse in a certain compartment (anterior, posterior or apical), the therapeutic conduct being individualized in each situation. In the case of symptomatic apical POP or after the failure of conservative treatment, the treatment of choice is the surgical one, with hysterectomy in the first place, followed by pelvic reconstruction procedures with the preservation of the uterus. These procedures can be performed through a vaginal approach, if access allows, or transabdominally, classically or through laparoscopy. Additionally, there are numerous procedures for ligamentous suspension of the remaining vaginal apex, thus having the freedom to combine different approaches with different procedures, with the aim of a lasting result. Regarding the recurrence rate, comparing vaginal hysterectomy followed by ligament fixation with native tissue with hysteropreservation interventions, there is a significant decrease in POP recurrence after hysterectomy. However, compared in general, no long-term difference in pelvic organ prolapse recurrence is observed. Moreover, being an invasive procedure that requires extensive dissection of the tissues, there is a longer duration of the operating time, with an above average hemorrhage in case of hysterectomy, the patients having a longer duration of hospitalization. The decision regarding the chosen surgical option must be taken together with the patient, after presenting the advantages and disadvantages of each method, as well as the evaluation of the biological state and the risks of a prolonged surgical intervention. An important factor is the existence of some gynecological background (metrorrhagia, endometrial polyps, uterine fibroids), an aspect that pleads for the excision of the uterus.

A Morphometric Study Analyzing the Anterior Epidural Space Volume Throughout Childhood

BACKGROUND: Following disc herniations, fragments migrate into the anterior epidural space within the lumbar spine. Although the volume of this area has been previously described in the adult population, the volume is relatively unknown within children. OBJECTIVES: Investigate the relative volume in the lumbar anterior epidural space within the growing spine by using imaging studies. STUDY DESIGN: Retrospective chart review. SETTING: University Medical Center in Lubbock Texas. A teaching hospital affiliated with Texas Tech University Health Sciences Center. METHODS: We conducted a retrospective review of the charts of pediatric patients seen at our institution from 2018 through 2020. Charts chosen for our investigation contained computed tomography imaging of the lumber spine, showing no deformities. Thirty patients were stratified equally among 3 age groups, 2-5 years old, 10-12 years old, and 16-18 years old. The anterior epidural space was measured in each patient 3 times using the previously reported method used by Teske et al (1). Results were compared with a combination of analysis of variance (ANOVA) and single tail paired t test. RESULTS: There was a statistically significant difference in the anterior epidural space size among age groups at all levels of the lumbar spine. When comparing only 2 groups together, the younger age group had anterior epidural space sizes significantly smaller than the other age group for all levels of the lumbar spine. The 10-12 age group had a significantly smaller space in the anterior epidural space than the 16–18-year olds only at the level of L2, L4, and L5 (P = 0.048,0.039, and 0.031, respectively). Within the 16–18-year age group, the anterior epidural space was significantly different between L4 and L3 and L2 and L3 (P &lt; 0.001 and P = 0.019, respectively). LIMITATIONS: Our study is limited by its retrospective nature and the sample size of the patient groups. Furthermore, the use of computed tomography imaging and not making physical measurements limits our accuracy. CONCLUSION: The volume of the anterior epidural space is smaller in the pediatric population than the adult population. The inability of herniated discs to fit within the epidural space in children and adolescents could potentially be the cause of the increased failure of conservative treatment for pediatric lumbar disc herniations. KEY WORDS: Anterior epidural space, lumbar herniated disc, low back pain, fossa corporis vertebralis dorsalis, free disc fragment, lumbar spine anatomy

Osteochondral Lesions of the Subtalar Joint: Clinical Outcomes in 11 Patients.

The purpose of this retrospective case series was to evaluate clinical outcomes following both conservative treatment and arthroscopic bone marrow stimulation (BMS) for the management of symptomatic subtalar osteochondral lesions (OCLs). All symptomatic subtalar OCLs with a minimum of 12 months follow-up having undergone either a conservative management or arthroscopic procedure were included. Patient-reported outcomes were collected via questionnaires consisting of the Foot and Ankle Outcome Score (FAOS), Numeric Rating Scale (NRS) of pain in rest, during walking, during stair climbing, and during running. In addition, return to sports data, return to work data, reoperations, and complications were collected and assessed. In total, 11 patients across 2 academic institutions were included (3 males, 8 females). The median age was 43 years (interquartile range [IQR]: 32-53). All patients underwent conservative treatment first; in addition, 9 patients underwent subtalar arthroscopic debridement with or without BMS. The median follow-up time was 15 months (IQR: 14-100). In the surgically treated group, the median NRS scores were 2 (IQR: 1-3) during rest, 3 (IQR: 2-4) during walking, 4 (IQR: 4-5) during stair climbing, 5 (IQR: 4-5) during running and the median FAOS score at final follow-up was 74 (IQR: 65-83). In the conservatively treated patients, the median NRS scores were all 0 (IQR: 0-0) and the median FAOS scores were 90 (IQR: 85-94). In the group of surgical treated patients, 4 were able to return to the same level of sports, 2 returned to a lower level of sports. Both conservatively treated patients returned to the sport and the same level of prior participation. All patients except one in the surgical group returned to work. This retrospective case series demonstrated that a high number of patients converted to surgery after initial conservative treatment. In addition, debridement and BMS show good clinical outcomes for the management of symptomatic subtalar OCLs at short-term follow-up. No complications nor secondary surgical procedures were noted in the surgically treated group. The high rate of failure of conservative treatment suggests that surgical intervention for symptomatic subtalar OCLs can be the primary treatment strategy; however, further research is warranted in light of the small number of patients.

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.

Management of Early Postoperative Bleeding After OAGB: A Single-center Experience.

One anastomosis gastric bypass (OAGB) has gained popularity among bariatric surgeons due to the shorter operative time, fewer sites for anastomotic leaks and internal herniation, shorter learning curve, ease of reversibility and revision with equivalent results to Roux en Y gastric bypass in terms of weight loss and co-morbidity resolution. We present our experience in managing early postoperative bleeding after OAGB. Patients who underwent OAGB in Bariatric Surgery Unit, Ain Shams University Hospitals between January 2016 and January 2023 were followed up for 30 days for early postoperative complications. Patients were 210 females (70%) and 90 males, with a mean age of 41.3±7.1 years, and mean preoperative body mass index of 45.2±6.1kg/m². The incidence of early postoperative bleeding, the sites of the bleeding and management strategy were reported. Fourteen of 300 patients (4.67%) developed early postoperative bleeding after OAGB. Intraluminal bleeding occurred in 4 patients, 3 of which were controlled by endoscopy and one by laparoscopic suturing. Intra-abdominal bleeding occurred in 10 patients, 7 of which were successfully managed conservatively, and 3 required laparoscopic management. Two cases had both intra-abdominal bleeding and intraluminal bleeding in the distal stomach, confirmed by intraoperative endoscopy, and controlled by laparoscopic suturing. Early postoperative bleeding after OAGB is a rare complication (4.67%). Conservative treatment is more successful in controlling intra-abdominal bleeding. In case of failed conservative treatment, laparoscopy is the method of choice. Most cases of intra-luminal bleeding need early endoscopic intervention.

Assessment of risk factors for the vertebral body kyphotic deformity progression in patients with type A1 injuries of the thoracolumbar junction

More than 60% of traumatic injuries of the spine occur in the zone of the thoracolumbar junction (TLJ), and 60–75% of these fractures are of a compression nature. Type A1 injuries are characterized by the least osteo-destructive changes compared to other injuries. Traditionally, they are treated conservatively. A number of studies conducted in the last 10 years, shows a high rate of failure of conservative treatment, as evidenced by the progression of kyphotic deformity of the compressed vertebral body. Most of these publications are devoted to osteoporotic lesions in aged patients, while this aspect has been little studied in patients of working age with normal bone density. Objective: to evaluate the factors influencing the risk of kyphotic deformity progression in patients of working age with type A1 traumatic injuries of the thoracolumbar junction. Materials and methods. The analysis of clinical cases of patients who visited the outpatient department of Romodanov Neurosurgery Institute of National Academy of Medical Sciences of Ukraine in the period from 2019 to 2022 with traumatic damage to the TLJ zone. Forty-seven victims who met the selection criteria were selected. Gender, age, body mass index, level of damage, location of the damaged endplate (caudal or cranial), bone tissue radiodensity, angular kyphotic deformity of the vertebral body, and pain intensity were considered as predictors. Depending on the presence or absence of deformity progression 2 months after the injury, the patients were divided into two clinical groups. The most clinically significant predictors were identified using the LASSO (Least Absolute Shrinkage and Selection Operator) regression method. Results. LASSO screening identified five potential predictors. The final logistic regression model after regularization demonstrated high predictive performance: the area under the ROC curve (AUC) was 0.907, and the predictive accuracy was 85%. When assessing the risk of kyphotic deformity progression in traumatic injuries of type A1 of the TLJ zone, age, bone density, angular kyphotic deformity of the vertebral body, and pain intensity are of the greatest importance, demonstrating a directly proportional relationship. A compressed caudal endplate is also associated with a higher risk of post-traumatic progression of angular kyphosis. The nomogram developed using the mentioned factors makes it possible to quantify the degree of risk when choosing a therapy strategy. Conclusions. The performed analysis made it possible to create a nomogram for predicting the increase in kyphotic deformity of the vertebral body in A1 fractures of TLJ region. The proposed model can be used for a rational assessment of the risk degree when choosing the optimal tactics for treating patients.

Older age and the presence of intrameniscal signs are risk factors for nonsurgical treatment failure of symptomatic intact discoid lateral meniscus.

The treatment for symptomatic intact discoid lateral meniscus (DLM) is controversial and the long-term clinical outcome remains unknown. The purpose of this study was to analyze the overall failure rate of nonsurgical treatment for symptomatic intact DLM and identify the risk factors for nonoperative management failure. Consecutive patients who underwent nonsurgical treatment for symptomatic intact DLM at our hospital from 2014 to 2017 were retrospectively reviewed. Patients were divided into Group A (failure group) and Group B (nonfailure group) based on overall failure criteria: conversion to surgery, progression of a tear on MRI re-examination, or severely abnormal International Knee Documentation Committee (IKDC) scores. Statistical analyses between the two groups were performed for demographic and radiographic characteristics. Multivariate regression analysis was used to determine the risk factors associated with worse outcomes. One-hundred and four knees in 96 patients were included in this study. After a mean follow-up of 76.9 ± 11.1months, 25 knees (24.0%) met the overall failure criteria. Multivariate regression analysis demonstrated that age and the presence of intrameniscus signals increased the risk of nonoperative management failure. The clinical criterion of age > 37.5years combined with the imaging criterion of the presence of intrameniscal signals predicted conservative treatment failure of symptomatic intact DLM with a sensitivity of 0.87 and a specificity of 0.91. Twenty-five (24.0%) knees that underwent nonsurgical treatment met the overall failure criteria after a mean follow-up of 76.9months. With increased age and the presence of intrameniscal signals, the nonoperative results become worse. III.

1198 Outcomes Following Internal Bracing for Anterior Sternoclavicular Joint Instability: A Systematic Review

Abstract Aim There is a paucity of data regarding optimal treatment strategies for atraumatic sternoclavicular joint (SCJ) instability, as this is a relatively uncommon aetiology. Atraumatic SCJ instability may be due to capsular laxity, muscle sequencing or a combination of both. This study aims to systematically review the literature regarding SCJ instability with isolated capsular laxity to determine whether anterior capsular surgical plication and augmentation with internal bracing can prevent further episodes of instability in a population that is refractory to non-operative management. Method Studies that reported functional surgical outcomes were identified using the search terms “sternoclavicular AND joint AND dislocation AND reconstruction”. Nine studies and a total of 111 patients were identified to have met the inclusion criteria. Results Of the 111 patients identified, 9% of patients reported residual instability. 5.4% required a reoperation due to persistent impairment of shoulder function related to SCJ instability or osteoarthritis. There were satisfactory reported outcomes in 91% of patients. Conclusions Internal stabilisation techniques for atraumatic sternoclavicular joint (SCJ) instability have shown to be an effective method to improve shoulder function and patient symptoms. Revision rates remained at only 5.4% with a significant improvement in functional status. Complications were rare and included haematoma formation and discharging wound site. Therefore, internal bracing techniques should be considered in patients with chronic anterior SCJ instability after a course of failed conservative treatment.

Long-term cost-effectiveness analysis of sacral neuromodulation in the treatment of severe faecal incontinence.

The aim of this study was to evaluate the long-term cost-effectiveness of sacral neuromodulation in the treatment of severe faecal incontinence as compared with symptomatic management. In the public health field, a micro-costing evaluation method was conducted from the perspectives of the health system and the society. The incremental cost-effectiveness ratio was used as a decision index, and we considered various scenarios to evaluate the impact of the cost of symptomatic management and percutaneous nerve evaluation success rate in its calculation. Clinical data were retrieved from a consecutive cohort of 93 patients with severe faecal incontinence undergoing sacral neuromodulation after a failure of conservative (pharmacological and biofeedback) and/or surgical (sphincteroplasty) first-line treatments were considered. The long-term incremental cost-effectiveness ratio comparing sacral neuromodulation versus symptomatic management was 14347€/QALY and 28523€/QALY from the societal and health service provider's perspectives, respectively. If the definitive pulse generator implant success rate was 100%, incremental cost-effectiveness would correspond to 6831€/QALY and 16761€/QALY, respectively. Sacral neuromodulation may be considered a cost-effective technique in the long-term treatment of severe faecal incontinence from the societal and health care sector perspectives. Improving patient selection and determining the predictive outcome factors for successful sacral neuromodulation in the treatment of faecal incontinence would improve cost-effectiveness.

Efficacy and Duration of Intra-Articular Autologous Micro-Fragmented Adipose Tissue in Athletes with Ankle Osteoarthritis: A 36-Month Follow-Up Study

Introduction: The intra-articular injection of autologous micro-fragmented adipose tissue (MAT) is increasingly used to manage pain and dysfunction in subjects with osteoarthritis (OA). The purpose of this retrospective study was to report the safety and clinical outcomes of intra-articular MAT in athletes with ankle OA. Methods: Participants were 21 symptomatic athletes aged 18–30 years suffering from mild-to-moderate ankle OA, who received 7 mL autologous MAT after failure of six-month conservative treatment. Clinical evaluation was performed before the procedure and at 6, 12, 24, and 36 months using the visual analog scale for pain, the American Orthopedic Foot and Ankle Society score and the Foot and Ankle Disability Index score. Patient satisfaction was assessed at 36 months. Results: The clinical scores documented a significant or marked improvement throughout the follow-up (p &lt; 0.05). However, at 36 months, they were significantly lower compared with the 24-month time point (p &lt; 0.05), although they were still significantly better than the baseline scores. There were no intraoperative or postoperative complications. Altogether, 81% of patients were very satisfied and 19% were satisfied. Conclusions: Intra-articular MAT injection appears to be a safe and effective treatment for ankle OA. In particular, it offers athletes wishing a fast return to their sports a new, minimally invasive therapeutic option.
