“…In previous research into ventilation in ankylosing spondylitis, diaphragm contribution was estimated by the ratio between the chest wall and abdominal wall motion which was measured by magnetometer 3) , optoelectronic plethysmography 5) , and laser techniques 4) . These methods are indirect assessments of diaphragmatic function.…”

Abstract.[Purpose] The purpose of the present study was to determine whether transient upper chest wall restriction would enhance diaphragmatic contribution to tidal volume in healthy subjects. [Methods] Changes of diaphragm thickness (ΔTdi) were studied by ultrasound in 24 healthy male subjects in the supine position. Tidal volume (Vt) and respiratory rate were measured by spirometer. ΔTdi with each breath was expressed as percentage of the thickness at the end of expiration (ΔTdi%) and the ratio of ΔTdi% to tidal volume was calculated (ΔTdi%/Vt). The upper rib cage was compressed with a sphygmomanometer cuff to restrict its motion. All parameters were measured in three conditions: during rib cage compression, prior to the compression, and subsequent to the compression.[Results] When upper rib cage compression was applied, ΔTdi% significantly increased, whereas it returned to baseline levels upon release of the compression. ΔTdi%/Vt tended to increase, however there was no significant difference. Subjects were divided into those who showed an increase in ΔTdi%/Vt (group 1: n=16) and those who showed a decrease (group 2: n=8). Prior to the compression, ΔTdi% and ΔTdi%/Vt of group 1 were higher than those of group 2.[Conclusion] These results suggest that in healthy male subjects transient upper rib cage ristriction may enhance diaphragmatic contribution to tidal volume, particularly in those subjects with low initial diaphragm recruitment.

ÖzetAmaç: Bu çalışmanın amacı; ankilozan spondilit (AS)'li hastalarda yaş ve cinsiyete göre düzeltilmiş göğüs ekspansiyonunun klinik pratikte kullanı-mının uygun olup olmadığını ve göğüs ekspansiyonunun pulmoner fonksiyonlar ve hastalık şiddeti ile ilişkisini araştırmaktır. Gereç ve Yöntem: Çalışmaya 82 AS'li hasta ve 42 sağlıklı gönüllü alındı. Hastalar, yaş, cinsiyet ve düzeltilmiş göğüs ekspansiyonuna göre; göğüs ekspansiyonu kısıtlanmış ve kısıtlanmamış olmak üzere iki gruba ayrıldı. Hastalar, klinik parametrelere ek olarak, Bath AS Disease Activity Index (BASDAI), Bath AS Functional Index (BASFI) ve Bath AS Metrology Index (BASMI) ile değerlendirildi. Bulgular: Zorlu vital kapasite ve 1. saniyedeki zorlu ekspiratuar hacim; göğüs ekspansiyonu kısıtlanmış hastalarda, kısıtlanmamış hastalar ve kontrol grubuna göre anlamlı derecede azalmış bulundu. Ağrı, BASFI ve BASMI skorları, göğüs ekspansiyonu kısıtlanmış grupta istatistiksel olarak anlamlı düzeyde yüksekti. Göğüs ekspansiyonu, klinik parametreler ve solunum fonksiyon testleri ile anlamlı derecede korele idi. Sonuç: AS'li hastalarda yaş ve cinsiyete göre düzeltilmiş göğüs ekspansiyonunun klinik pratikte kullanılmasının daha uygun olduğu ve göğüs ekspansiyonunun pulmoner fonksiyonlar ve hastalık şiddeti ile ilişkili olduğu kanısına varıldı.

Metarials and Methods: Eighty-two patients with AS and 42 healthy controls were included in the study. The patients were divided into two groups according to chest expansion corrected by age and sex: restricted and non-restricted groups. Additional to the clinical evaluation, the Bath AS Disease Activity Index (BASDAI), Bath AS Functional Index (BASFI), and Bath AS Metrology Index (BASMI) were used to evaluate disease activity, functional impairment, and mobility, respectively. Results: Forced vital capacity and forced expiratory volume in the first second were significantly decreased in the restricted group when compared to the non-restricted and control groups. Pain, BASFI, and BASMI scores were significantly higher in the restricted group compared to the non-restricted one. Chest expansion was significantly correlated with clinical parameters and pulmonary function tests. Conclusion: Chest expansion measurement corrected for age and sex is appropriate for clinical practice and chest expansion is associated with pulmonary functions and disease severity.

“…This kyphotic deformity may make spine muscles under continuous strain and generate increasing back pain attributable to muscle fatigue [5]. The deteriorated thoracolumbar kyphosis even involves visceral compression resulting in intra-abdominal complications or impaired respiratory function [7].…”

Study design A retrospective clinical study. Objective To evaluate the outcomes of two-level (T12 and L3) pedicle subtraction osteotomy (PSO) for severe thoracolumbar kyphosis in ankylosing spondylitis (AS), and to discuss the surgical strategies of this surgery. Background Cases were limited on the results of twolevel PSO for correction of severe kyphosis caused by AS, nor on surgical strategies of this type of surgery. Methods From March 2006 to December 2010, nine consecutive AS patients with severe kyphotic deformity, underwent T12 and L3 PSOs. Chin-brow vertical angle (CBVA) and radiographic assessments which contain thoracic kyphosis (TK), lumbar lordosis (LL), global kyphosis (GK), and sagittal vertical axis were carefully recorded pre and postoperatively to evaluate the sagittal balance. Intra and postoperative complications were also registered. All patients were asked to fill out Oswestry Disability Index before surgery and at the last follow-up visit. Results All nine patients (8M/1F), averaged 41.4 years old (range 35-51 years), were received two-level (T12 and L3) PSO, and were followed up after surgery for a mean of 39.9 months (range 24-68 months). Good cosmetic results were achieved in all patients. Mean correction at two-level PSO was 67.9 ± 5.5°. All CBVA, TK, LL, and GK were changed significantly after surgery (P \ 0.05), the mean amount of correction of which were 59.5 ± 13.8, 34.7 ± 3.8, 33.2 ± 2.4, and 54.0 ± 14.8 degrees, respectively, and with a small loss of correction at the last followup visit. Sagittal imbalance was significantly improved from 27.3 ± 4.4 to 3.4 ± 0.7 cm postoperatively. Neither mortalities nor any major neurological complications were found. The mean ODI score was significantly improved from 53.4 ± 15.5 before surgery to 8.2 ± 4.7 at the last visit. Conclusion The outcomes of follow-up showed that twolevel (T12 and L3) PSO can effectively and safely correct severe thoracolumbar kyphosis in AS.
