These patients were divided into two groups: in group I (n = 29) a lower instrumented vertebra corresponded to the sagittal stable one and in group II (n = 7) - this vertebra located proximally.<\/jats:p>Results<\/jats:sc>:<\/jats:bold>The mean preoperative kyphosis was 79.3\u00b0 \u00b1 11.6\u00b0, the postoperative \u2013 40.6\u00b0 \u00b1 11.9\u00b0 (correction of 49.9%), loss of correction was 4.9\u00b0 \u00b1 7.0\u00b0. Sagittal balance changed from \u22120.3 \u00b1 3.2 cm before surgery to \u22121.7 \u00b1 2.1 cm after surgery. Distal junctional kyphosis developed in 1 case (4%) in Group I, and in 5 cases (71%) in Group II.<\/jats:p>Conclusion<\/jats:sc>:<\/jats:bold>A distal level of instrumentation ending at the first lordotic vertebra is not justified and causes violation of sagittal balance and development of distal junctional kyphosis. The inclusion of a sagittal stable vertebra in fusion prevents the development of this undesirable situation.<\/jats:p>","DOI":"10.1515\/folmed-2015-0016","type":"journal-article","created":{"date-parts":[[2015,10,2]],"date-time":"2015-10-02T13:53:01Z","timestamp":1443793981000},"page":"29-36","source":"Crossref","is-referenced-by-count":10,"title":["Selection Of The Optimal Level Of Distal Fixation For Correction Of Scheuermann\u2019s Hyperkyphosis"],"prefix":"10.1515","volume":"57","author":[{"given":"Mikhail V.","family":"Mikhaylovskiy","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Artem N.","family":"Sorokin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vjacheslav V.","family":"Novikov","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexander S.","family":"Vasyura","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"374","reference":[{"key":"ref131","doi-asserted-by":"crossref","first-page":"1611","DOI":"10.1097\/00007632-199407001-00010","article-title":"Radiographic analysis of sagittal plane alignment and balance in standing volunteers and patients with low back pain matched for age sex and size : a prospective controlled clinical study","volume":"19","author":"Jackson","year":"1994","journal-title":"Spine"},{"key":"ref31","doi-asserted-by":"crossref","first-page":"1680","DOI":"10.1097\/00007632-199408000-00005","article-title":"An analysis of sagittal curves and balance after Cotrel -
