ABSTRACT Objective: To evaluate retrospectively the results related to the use of pelvic fixation with alar-iliac S2 screw in individuals with myelomeningocele. Methods: Retrospective study of cases surgically treated with this technique, between January 2015 and March 2018 at the Pequeno Principe Children's Hospital. Radiographic images and clinical records were analyzed in search of complications. Results: Twelve patients with mean age of 13.3 years were treated at the time of surgery. The mean follow-up was 11.5 months. The mean of the highest magnitude curve measured by the Cobb angle in the preoperative period was 83.8°; while in the last postoperative follow-up was 29.5° (correction of 65%). The mean pelvic obliquity was 23.1° in the preoperative period and in the postoperative was 7.1° (correction of 69%). Only 2 cases (17%) with complications associated with material failure at the level of sacroiliac fixation, due to the unilateral release of the head of the polyaxial S2 iliac screw. Conclusions: The technique of pelvic fixation in the scoliosis secondary to myelomeningocele with the use of S2 alar-iliac screws has shown satisfactory results, with only two complications (17%) directly related to pelvic fixation in the operated cases.

ABSTRACT Objective The use of pedicle screws was a milestone for modern spinal surgery. This type of fixation, due to its superior biomechanics, gave greater fixation power, greater capacity to withstand the pulling forces and, therefore, greater stability and lower rates of pseudoarthrosis. Fixation of the lumbosacral junction, even with the development of these new implants, remains a challenge mainly because the considerable rates of pseudoarthrosis. The use of iliac screws solves the biomechanical difficulties. However, its use shows high rates of surgical wound problems. The S2-Alar-Iliac screw (S2AI) came as a solution to these complications. The lack of studies about anatomical and anthropometric parameters in the Brazilian population justifies the study. Methods Eleven hip tomographies of Brazilian adult males were analyzed by four evaluators. The right and left sides were considered. In each patient, measurements were made of greater and shorter bone length, greater and smaller bone diameter, distance from the entry point to the skin, sagittal and axial angles related to the hypothetical insertion of an S2AI screw and compared to the same measurements obtained with the iliac screw. Results The mean bone length was 136.7 mm, the greatest bone diameter was 24.8 mm, the smallest bone diameter was 19.7 mm and the distance from the screw to the skin was 42.1 mm for the S2AI screw. Conclusions The obtained data present an average of the sample that can be useful in the decision of the surgical technique in the studied group.

ABSTRACT Objective: Lumbosacral fixation presents problems in its arthrodesis, mainly due to pseudoarthrosis. Iliac screws minimize this problem, however, they show problems in the operative wound. The S2-Alar-iliac (S2AI) screw presents a lower rate of these complications. The anatomical differences between the populations and the sexes analyzed in the literature justify the study of the S2AI screw technique in Brazilian women. Methods: A total of 14 adult female CT scans were analyzed by 4 evaluators. Results: The mean bone length was 131.8 mm, the largest bone diameter was 22.6 mm, and the smallest bone diameter was 22.6 mm. Conclusions: The data presented are compatible with the literature and may assist spine surgeons in choosing the best implant and surgical technique.

Object Long-segment spinal instrumentation ending at the sacrum places substantial biomechanical stress on sacral screws. Iliac (pelvic) screws relieve some of this stress by supplementing the caudal fixation. It remains an open question whether there is any clinically significant difference in sacropelvic fixation with bilateral versus unilateral iliac screws. The primary purpose of this study was to compare clinical and radiographic complications in the use of bilateral versus unilateral iliac screw fixation. Methods The authors retrospectively reviewed 102 consecutive spinal fixation cases that extended to the pelvis at a single institution (University of California, San Francisco) in the period from 2005 to 2012 performed by the senior authors. Charts were reviewed for the following complications: reoperation, L5–S1 pseudarthrosis, sacral insufficiency fracture, hardware prominence, iliac screw loosening, and infection. The t-test, Pearson chi-square test, and Fisher exact test were used to determine statistical significance. Results The mean follow-up was 31 months. Thirty cases were excluded: 12 for inadequate follow-up, 15 for lack of L5–S1 interbody fusion, and 3 for preoperative osteomyelitis. The mean age among the 72 remaining cases was 62 years (range 39–79 years). Forty-six patients underwent unilateral and 26 bilateral iliac screw fixation. Forty-one percent (n = 19) of the unilateral cases and 50% (n = 13) of the bilateral cases were treated with reoperation (p = 0.48). In addition, 13% (n = 6) of the unilateral and 19% (n = 5) of the bilateral cases developed L5–S1 pseudarthrosis (p = 0.51). There were no sacral insufficiency fractures. Thirteen percent (n = 6) of the unilateral and 7.7% (n = 2) of the bilateral cases developed postoperative infection (p = 0.70). Conclusions In a retrospective single-institution study, single versus dual pelvic screws led to comparable rates of reoperation, iliac screw removal, postoperative infection, pseudarthrosis, and sacral insufficiency fractures. For spinopelvic fixation, placing bilateral (vs unilateral) pelvic screws produced no added clinical benefit in most cases.

Purpose: Osgood-Schlatter disease (OSD) is common causes of knee pain in adolescent. Most patients respond to conservative treatment. However surgical treatment has been recommended for unresolved OSD. The aim of this study was to determine the outcomes of arthroscopic ossicle excision in athletes with unresolved OSD. Methods: Between September 2008 and November 2014, arthroscopy was performed 11 knees of 11 patients with OSD. The inclusion criteria were patients who underwent arthroscopic surgery with more than one year follow-up after surgery. Patients have a documented history of OSD with refractory pain over the tibial tubercle for a mean of 15.5 months (range, 7 to 24 months; SD, 7.5 months). The mean age was 23 years (range, 19 to 29 years; SD, 2.8 years). The mean follow-up period was 66.1 months (range, 15 to 96 months; SD, 25.6 months). Results: The mean return the sports activities after the surgery was 6.7 weeks (range 5 to 9 weeks; SD 1.3 weeks). The mean Kujala patellofemoral score improved from 82.9 (range 80 to 88 points; SD 2.6) preoperatively to 98.5 (range 96 to 100 points; SD 1.6) at final follow-up (p<0.01).In addition, the mean Lysholm knee scale was 87.5 (range 86 to 90 points; SD 1.7) in the preoperative period and increased to 96.9 (range 94 to 100 points; SD 2.5) at final follow-up(p<0.01). The mean Tegner activity level was 7.5 (range 6 to 8; SD 0.9) in the preoperative period and increased to 8.5 (range 7 to 9; SD 0.9) after surgery (p<0.01). Conclusions: We investigated the functional outcomes after arthroscopic treatment of unresolved OSD in athletes. In the all athletes, the arthroscopic treatment of OSD yielded satisfactory functional recovery. No postoperative complication were located. All patients were able to return the same level athletic activity. Level of evidence: Therapeutic Level IV. Key terms: Osgood-Schlatter disease, athletes, knee arthroscopy, ununited ossicle

Background: Tendon injuries are commonly seen in sports medicine practice. Many elite players involved in high-impact activities develop patellar tendinopathy (PT) symptoms. Of them, a small percentage will develop refractory PT and need to undergo surgery. In some of these patients, surgery does not resolve these symptoms. Purpose: To report the clinical results in a cohort of athletes who underwent further surgery after failure of primary surgery for PT. Study Design: Case series; Level of evidence, 4. Methods: A total of 22 athletes who had undergone revision surgery for failed surgical management of PT were enrolled in the present study. Symptom severity was assessed through the Victorian Institute of Sport Assessment Scale for Patellar Tendinopathy (VISA-P) upon admission and at the final follow-up. Time to return to training, time to return to competition, and complications were also recorded. Results: The mean age of the athletes was 25.4 years, and the mean symptom duration from the index intervention was 15.3 months. At a mean follow-up of 30.0 ± 4.9 months, the VISA-P score improved 27.8 points ( P < .0001). The patients returned to training within a mean of 9.2 months. Fifteen patients (68.2%) returned to competition within a mean of 11.6 months. Of these 15 patients, a further 2 had decreased their performance, and 2 more had abandoned sports participation by the final follow-up. The overall rate of complications was 18.2%. One patient (4.5%) had a further revision procedure. Conclusion: Revision surgery was feasible and effective in patients in whom PT symptoms persisted after previous surgery for PT, achieving a statistically significant and clinically relevant improvement of the VISA-P score as well as an acceptable rate of return to sport at a follow-up of 30 months.

Background: There is no consensus on the ideal treatment for partial articular supraspinatus tendon avulsion (PASTA) lesions without tendon damage. Purpose: To introduce a novel “retensioning technique” for arthroscopic PASTA repair and to assess the clinical and radiologic outcomes of this technique. Study Design: Case series; Level of evidence, 4. Methods: A retrospective analysis was performed on 24 patients whose PASTA lesion was treated using the retensioning technique between January 2011 and December 2015. The mean ± SD patient age was 57.6 ± 7.0 years (range, 43-71 years), and the mean follow-up period was 57.6 ± 23.4 months (range, 24.0-93.7 months). Sutures were placed at the edge of the PASTA lesion, tensioned, and fixed to lateral-row anchors. After surgery, shoulder range of motion (ROM) and functional scores (visual analog scale [VAS] for pain, VAS for function, American Shoulder and Elbow Surgeons [ASES] score, Constant score, Simple Shoulder Test, and Korean Shoulder Score) were evaluated at regular outpatient visits; at 6 months postoperatively, repair integrity was evaluated using magnetic resonance imaging (MRI). Results: At 12 months postoperatively, all ROM variables were improved compared with preoperative values, and shoulder abduction was improved significantly (136.00° vs 107.08°; P = .009). At final follow-up (>24 months), the VAS pain, VAS function, and ASES scores improved, from 6.39, 4.26, and 40.09 to 1.00, 8.26, and 85.96, respectively (all P < .001). At 6 months postoperatively, 21 of the 24 patients (87.5%) underwent follow-up MRI; the postoperative repair integrity was Sugaya type 1 or 2 for all of these patients, and 13 patients showed complete improvement of the lesion compared with preoperatively. Conclusion: The retensioning technique showed improved ROM and pain and functional scores as well as good tendon healing on MRI scans at 6-month follow-up in the majority of patients. Thus, the retensioning technique appears to be reliable procedure for the PASTA lesion.

Abstract Purpose This study updates the current evidence on the role of allografts versus autografts for medial patellofemoral ligament (MPFL) reconstruction in patients with patellofemoral instability. Methods The study was performed according to the PRISMA guidelines. In March 2021, a literature search in the main online databases was performed. Studies reporting quantitative data concerning primary MPFL reconstruction using an allograft were considered for inclusion. The Coleman Methodology Score was used to assess the methodological quality of the selected articles. Results Data from 12 studies (474 procedures) were retrieved. The mean follow-up was 42.2 (15–78.5) months. The mean age was 21.1 ± 6.2 years. 64.9% (285 of 439) of patients were female. At the last follow-up, the Tegner (p < 0.0001), Kujala (p = 0.002) and the Lysholm (p < 0.0001) scores were minimally greater in the autografts. The similarity was found in the rate of persistent instability sensation and revision. The allograft group evidenced a lower rate of re-dislocations (p = 0.003). Conclusion Allografts may represent a feasible alternative to traditional autograft for MPFL reconstruction in selected patients with patellofemoral instability. Allograft tendons yielded similar PROMs, rates of persistent instability, and revision. Allograft reconstructions tended to have modestly lower re-dislocation rates. Level of evidence IV.

Objectives Revascularization according to the angiosome concept is of proven importance for limb salvage in chronic limb threatening ischaemia but it is not always practicable. Bifurcated bypasses could be considered as an option when an endovascular approach is not feasible or has already failed and a single bypass would not allow direct revascularization of the ischaemic area. Bifurcated bypasses are characterized by landing on two different arteries, the main artery (in direct continuity with the foot vessels) and the secondary one (perfusing the angiosome district). The aim of this study is to evaluate the safety and effectiveness of bifurcated bypass in chronic limb threatening ischaemia. Methods Thirty-five patients were consecutively treated with a bifurcated bypass for chronic limb threatening ischaemia from January 2014 to December 2019 in a single vascular surgery centre. Data from clinical records and operative registers were collected prospectively in an electronic database and retrospectively analysed. Primary and primary assisted bypass patency, amputation-free survival, morbidity and mortality rates at 12 and 24 months were analysed. Results Mean follow-up period was 25.1 months (range 2–72 months). Thirty-six bifurcated bypasses were performed on 35 patients (age 75.3 ± 7.2 years; 69.4% were male). According to Wound, Ischemia, foot Infection classification 22.2% belonged to stage 3 and 77.8% to stage 4 and the mean Rutherford’s class was 5.1 ± 0.7. Immediate technical success was 100%. Early mortality and morbidity rates were respectively 5.5%, and 33.3%; foot surgery was performed in 50% of cases with wound healing in all patients. Primary patency and primary assisted bypass patency were 96.7% and 100% at 6 months; 85.2% and 92% at 12 months, 59.9% and 73.4% at 24 months, respectively. Amputation-free survival at 12 and 24 months was, respectively, 95.6% and 78.8%. Overall survival rates at 12 and 24 months were respectively 94.4% and 91.6%. Conclusions Bifurcates bypass can provide good results in patients with chronic limb threatening ischaemia without endovascular option, especially in diabetic ones. Bifurcated bypass is a complex surgical solution, both to be planned and performed, and it is quite invasive for frail patients that should be accurately selected.

INTRODUCTION CRH in patients with ischemic heart disease is recommended by the different clinical practice guidelines with an IA level of evidence, with an important role in reducing cardiovascular mortality and hospital readmissions during follow-up. OBJECTIVE The goal of this study is to show the 4-year clinical results of a population of patients who participated in an CRH program after an Acute Coronary Syndrome (ACS). METHODS Between May/2014 and September/2017, 221 patients who had recently presented an ACS completed the 12 weeks of phase II of the CRH program at our center. In May/2020 we collected epidemiological, clinical and echocardiographic information at the time of the acute cardiovascular event; and we evaluate the current vital status of the patients and the incidence of readmissions for: angina, HF, new ACS, or arrhythmic events. RESULTS Of the 221 patients, 182 were men (82%). The mean age of our population was 58.3 ± 7.8 years. 58% (129 patients) suffered from ST-elevation ACS. The mean time of hospital stay was 6.20 ± 2.9 days. An echocardiogram was performed at discharge, which showed an average LVEF of 56 ± 6%. Eight patients (4%) developed early Ventricular Fibrilation (VF) during the acute phase of ACS. Among the classic CVRF, smoking (79%) was the most prevalent, followed by dyslipidemia (53%) and hypertension (47%). The mean time from hospital discharge to the start of phase II RHC was 42 ± 16 days. The overall incidence of events was 9%: 10 patients suffered reinfarction during follow-up, and 7 were readmitted for unstable angina, all of whom underwent PCI; no patient was admitted for HF; and none of the 8 patients with early VF had a new tachyarrhythmia, registering a single admission for VT during follow-up. None of the patients had sustained ventricular tachyarrhythmias during exercise-training. At the mean 4.5-year follow-up, 218 patients were still alive (98%). CONCLUSION The incidence of CV events in the follow-up of our cohort was low, which can be explained by the fact that it is a young population, with an LVEF at low limits of normality at discharge, which is one of the most important predictors in the prognosis after an ischemic event. As an improvement, we must shorten the time until the start of phase II of the program. CRH shows once again its clinical benefit after an ACS, in consonance with the existing evidence.

Background: The objective of this study was to report the results of a new minimally invasive Achilles reconstruction technique and to assess the perioperative morbidity, medium- to long-term outcomes, and functional results. Methods: Our series was comprised 14 patients (11 men and 3 women), with a mean age of 45.6 years at surgery. Each patient had a chronic Achilles tendon rupture. The mean interval from rupture to surgery was 5.5 months (range, 2-10). The mean total follow-up was 30.1 months (range, 12-78). All patients were operated with a central turndown flap augmented with free semitendinosus tendon graft and percutaneous sutures in a minimally invasive approach assisted by endoscopy. The patients underwent retrospective assessment by clinical examination, the American Orthopaedic Foot & Ankle Society (AOFAS) ankle and hindfoot score, and the Achilles Tendon Total Rupture Score (ATRS). Paired t tests were used to assess the preoperative and postoperative AOFAS scores, ATRS scores, and ankle range of motion. Results: The length of the defect ranged from 3 to 8 cm (mean, 5.1), while the length of the turndown flap ranged from 8 to 13 cm (mean, 10.1). The mean AOFAS score improved from 64.5 points preoperatively to 96.9 points at last follow-up. The mean ATRS score improved from 49.4 preoperatively to 91.4 points at last follow-up. None of the patients developed a wound complication. No patient had a rerupture or sural nerve damage. Conclusion: All patients in our study had a favorable outcome with no complications. We believe that with this triple-repair technique, one can achieve a strong and robust repair such as in open surgery while at the same time reducing the incidence of complications. Level of Evidence: Level III, retrospective comparative study.
