Abstract Background: This study aims to evaluate the effects of bracing on the Cobb’s angle (CA) and spinopelvic parameters in adolescent idiopathic scoliosis (AIS) patients. Methods: A total of 51 AIS patients who received bracing treatment between January 2018 and August 2019 were retrospectively analyzed. The pro-bracing and in-bracing radiographs were analyzed with regard to the spinopelvic parameters. The CA, pelvic coronal obliquity angle (PCOA), thoracolumbar kyphosis (TK), lumbar lordosis (LL), pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), sagittal vertical angle (SVA) and coronal vertical angle (CVA) were measured. Results: The mean age at the initiation of bracing was 13.6 ± 1.5 years. The mean pro-bracing CA was 24.0° ± 6.3°. There were no statistically significant differences between pro-bracing and in-bracing measurements of SVA and CVA. However, there were statistically significant differences between the pro-bracing and in-bracing measurements of the CA, PCOA, TLK, LL, PT and SS. A significant correlation was observed between PT variation and TLK variation in the sagittal plane. In the coronal plane, the PCOA variation was correlated to pro-bracing PCOA. Conclusion: Bracing effects of AIS can be extended to the pelvis. The pelvis should retro-rotate correspondingly to TLK hypokyphosis on sagittal plane, whereas in coronal plane, pelvic obliquity was improved independently.

Orthotic Treatment

In this prospective study, the effectiveness and biomechanical factors of spinal orthoses in the treatment of moderate adolescent idiopathic scoliosis (AIS) patients were investigated. In the first 20 months of orthotic treatment, the values of standing AP Cobb's angle, apical vertebral rotation, lumbar lordosis as well as thoracic kyphosis showed significant reduction (P<0.05), however, the angle of trunk inclination and trunk listing did not. The values of those reducible parameters reached their lowest values within the first 12 months of orthotic treatment and then the values gradually increased but they were still below the prebrace values. The mean pressure of The pressure pads was found to be 7.09±1.77kPa (53.2±13.3mmHg) while the mean tension of the straps was 26.8±5.2N. The standing AP Cobb's angle strongly correlated with the pad pressure (correlation coefficient=0.931, p<0.05) and strap tension (correlation coefficient=0.914, p<0.05). The strap tension and pad pressure strongly correlated and the correlation coefficient was 0.873 (p<0.05). This suggests that in the consideration of biomechanical function of spinal orthoses, the focus may be upon how tightly the orthosis was fastened and if the location and direction of the pressure pads are correct. Therefore, for enhancing the effectiveness of orthotic treatment, an independent standard tension should be set in each strap, and regular and close monitoring is needed.

Orthotic treatment is the most commonly used non-surgical treatment method for adolescent idiopathic scoliosis (AIS). This study determined whether treatment outcome correlates with how often and how well children with AIS wear their orthoses. Eighteen (18) subjects (3M, 15F) who were diagnosed with idiopathic scoliosis and had wom their orthoses from 6 months up to 1 year participated in this study. All subjects were prescribed Boston braces to be wom full time (23hrs/day). Twelve (12) subjects who completed their brace treatment were included in the data analysis. Three (3) treatment outcomes were classified as improvement, no change and deterioration. The quality of the brace wear was assessed by how often the brace was wom with zero force, below 80%, between 80 to 120%, and above 120% of the load level prescribed in the clinic. The quantity of brace wear was determined by how many hours per day they wore their brace. Subjects who wear their braces tighter and for more hours per day seem to have better outcomes.

Reikšminiai žodžiai: koronarinis balansas, jaunatvinė idiopatinė skoliozė, žemiausio fiksuoto slankstelio nuokrypis, viršūninio slankstelio pasivertimas, Kobo kampas. Skoliozė – tai trijų dimensijų stuburo deformacija, apibūdinama kaip šoninis stuburo iškrypimas koronarinėje plokštumoje daugiau kaip 10°. Operacinis gydymas rekomeduojamas jaunuoliams, kai Kobo kampas viršija 45°–50°. Chirurginio gydymo esmė – saugi derotacija, lemianti stuburo balanso atkūrimą, o ne maksimali stuburo korekcija koronarinėje plokštumoje. Tikslas. Įvertinti radiologinius stuburo koronarinės plokštumos parametrus prieš ir po chirurginio jaunatvinės idiopatinės skoliozės (Lenke 1 tipo) gydymo. Tyrimo medžiaga ir metodai. Tiriamieji – 46 pacientai, chirurgiškai gydyti dėl jaunatvinės idiopatinės skoliozės (Lenke 1 tipo) bei stebėti 2 metus. Visi operuoti vienoje ligoninėje. Dviejų krypčių rentgenogramos stovint buvo atliktos prieš operaciją ir iškart po jos bei praėjus 1,3 mėnesio ir 2 metams po operacijos. Naudojantis jomis ir norint įvertinti stuburo išsilyginimą koronarinėje plokštumoje, buvo apskaičiuotas Kobo kampas, koronarinis balansas ir šoninio lenkimo testo, kuris atliktas tik prieš operaciją, rezultatai. Norint įvertinti nefiksuotų slankstelių pokyčius po operacijos, vertintas žemiausio fiksuoto slankstelio kampas ir viršutinis viršūninio slankstelio pasivertimas. Duomenys apdoroti SAS ir „Microsoft Excel 2013“ programomis. Rezultatai. 40 moterų ir 6 vyrai, sergantys jaunatvine idiopatine skolioze, buvo įtraukti į šią studiją. Vidutinis pacientų amžius – 14,1 metų. Vidutinė korekcija po operacijos krūtininėje stuburo dalyje buvo 32,76° (santykinė korekcija 65,04 proc.), juosmeninėje – 27,41° (69,66 proc.). Per dvejus metus po operacijos buvo prarasta 0,27° ± 4,52° (tai 1,53 proc. pasiektos korekcijos, p &lt; 0,05) pasiektos krūtininėje stuburo dalyje bei 1,61° ± 5,55° (13,48 proc., p &lt; 0,05) juosmeninėje. Korekcija krūtininėje stuburo dalyje buvo 38,85 proc. didesnė (p &lt; 0,05) nei prognozuota pagal šoninio lenkimo testo rezultatus. Koronarinis balansas buvo pagerintas 3,62 mm pacientų su subalansuotu stuburu prieš operaciją grupėje, bet suprastėjo 7,67 mm pacientų, prieš operaciją buvusių su subalansuotu stuburu, grupėje. Buvo rasta silpna koreliacija (rs = 0.34668 ir p-valu = 0.0183) tarp žemiausio fiksuoto slankstelio kampo bei nefiksuotų slankstelių skaičiaus. Išvados. Pooperacinės Lenke 1 tipo skoliozės gydymo išeitys negali būti nustatytos pagal linkio kryptį. Laikotarpiu po operacijos dalis per operaciją pasiektos korekcijos prarandama, žymiau tai pastebima juosmeninėje stuburo dalyje. Matuoti koronarinį balansą iš karto po operacijos nėra būtinybės, nes tai kliniškai nėra svarbu. Fiksuotas segmentas virš nefiksuoto segmento gali pakeisti nefiksuoto segmento biomechaniką. Šoninio lenkimo testas galėtų turėti vertės prognozuojant būsimos operacijos rezultatus juosmeninėje dalyje, tačiau krūtininėje dalyje šis testas prognostiškai nepatikimas, nes pasiekiama didesnė, nei tikėtasi, korekcija.

The efficacy of orthotic treatment for children with abnormal spinal curvature has been hampered by the lack of comprehensive information about wear characteristics. A battery-powered microcomputer system was developed to monitor loads exerted by orthoses used to treat children with spinal deformities during daily living. The system not only records how well the orthosis has been used, but also helps to ensure that the orthosis is being worn as prescribed. Data acquisition is controlled by a microcontroller and can be programmed to have sample intervals ranging from 1 second to 1 hour. Low power control circuitry is designed so that the system can be operated by a battery. In a preliminary study, 16 subjects (3M, 13F) used this system from 1 to 16 days (9.3±5.0) with the prescribed hours between 16 to 23 hours (22.3±1.3). This study demonstrated the feasibility of the approach, and that this device may increase the understanding of orthotic mechanics, and may help patients to wear their orthoses in a better way.

Összefoglaló. Bevezetés: Nincs egységesen elfogadott álláspont, hogy a serdülőkori idiopathiás gerincferdülés sebészi korrekcióját melyik életkorban optimális elvégezni. Világszerte 11 éves kortól akár (kezeletlen esetben) 50–60 éves korig végeznek fúziós műtétet a betegségben, 63–83%-os átlagos koronális síkú korrekciós hatékonysággal. Célkitűzés: Célul tűztük ki, hogy felmérjük a gerinckorrekciós műtétek hatékonyságát három dimenzióban, illetve a páciens életkorának függvényében. Módszerek: A vizsgálatba 23, serdülőkori idiopathiás gerincferdüléssel diagnosztizált beteget (12 fő 17 évnél fiatalabb, 11 fő 17 évnél idősebb) vontunk be. Minden betegnél csavaros derotációt és spondylodesist végeztünk, és a beavatkozás előtt és után EOS 2D/3D felvételeket, majd sterEOS 3D rekonstrukciókat készítettünk. A következő paramétereket számítottuk: Cobb-fok, háti kyphosis, ágyéki lordosis, apicalis csigolyarotáció, maximális csigolyarotáció. A különböző életkorú csoportok közötti különbséget kétmintás t-próbával, illetve Wilcoxon-féle próbával vizsgáltuk. Eredmények: A gerinckorrekciós műtétek során a koronális síkú eltérést 78,2%-ban (átlagosan 55,1 Cobb-fokról 12,0 Cobb-fokra), az apicalis csigolyarotációt 56,7%-ban (átlagosan 21,0 fokról 9,1 fokra) tudtuk korrigálni. A 17 éves életkor után operált páciensek esetén átlagosan 79,2%-os Cobb-fok-csökkenést értünk el, míg a fiatalabb betegcsoportban 77,0%-ban korrigáltuk a koronális főgörbületet (p = 0,614). Az idősebb betegcsoportban szignifikánsan kevésbé sikerült az apicalis csigolyarotáció korrekciója (átlagosan 38,1%; 21,8 fokról 12,4 fokra), mint a fiatalabb pácienseknél (átlagosan 68,5%; 20,2 fokról 6,2 fokra; p = 0,016). Következtetés: Összességében a nemzetközi publikációknak megfelelő korrekciót értünk el. A koronális síkban közel azonos korrekciós hatékonyság figyelhető meg a különböző életkorú betegcsoportok között, a csigolyarotáció azonban 17 éves életkor előtt hatékonyabban korrigálható. Orv Hetil. 2021; 162(39): 1573–1578. Summary. Introduction: There is no clear recommendation for the optimal age to perform corrective surgery in adolescent idiopathic scoliosis. Fusion surgery is performed from the age of 11 to 50–60 years, with an average coronal plane correction efficiency of 63–83%. Objective: We aimed to evaluate the effectiveness of correction surgeries in three dimensions in adolescent idiopathic scoliosis. In addition, our objective was to examine the influence of the patient’s age on the correction. Methods: The study included 23 patients with adolescent idiopathic scoliosis (12 patients younger than 17 years, 11 patients older than 17 years). All patients underwent screw-derotation and spondylodesis and underwent EOS 2D/3D imaging before and after the operation, followed by sterEOS 3D reconstructions. The following parameters were calculated: Cobb degree, thoracic kyphosis, lumbar lordosis, apical vertebral rotation, maximal vertebral rotation. Differences between different age groups were examined by paired-sample t-test and Wilcoxon rank sum test. Results: The mean efficiency of correction surgeries was 78.2% in the coronal plane (from an average of 55.1 Cobb degrees to 12.0 Cobb degrees) and 56.7% in the axial plane (from an average of 21.0 degrees to 9.1 degrees). We achieved an average 79.2% reduction of Cobb angle in patients operated after the age of 17 years, which was 77.0% in the younger group (p = 0.614). Apical vertebral rotation correction was significantly less successful in the elderly group (mean 38.1%; from 21.8 degrees to 12.4 degrees) than in patients operated before the age of 17 years (mean 68.5%; from 20.2 degrees to 6.2 degrees; p = 0.016). Conclusion: We achieved scoliosis correction in line with the international publications. Nearly the same correction efficiency was observed between different age groups of patients in the coronal plane. However, vertebral rotation can be derotated more effectively before the age of 17 years. Orv Hetil. 2021; 162(39): 1573–1578.
