Rare and overlooked two diagnoses in low back pain: Osteitis condensans ilii and lumbosacral transitional vertebrae

Abstract

Aim: In this study, we investigated the prevelance of osteitis condensans ilii (OCI) and lumbosacral transitional vertebra (LSTV), relationship of these diseases with age and gender, and whether there was a relationship between these two conditions. 

Methods: The computed tomography (CT) scans of 599 patients who underwent lumbar CT between January 2016 and March 2016 due to lumbar pain were evaluated retrospectively. All of the CT scans were performed with a 16-slice CT scanner. For each patient; age, gender, LSTV anomaly presence and type (lumbalisation, sacralization), and presence and side information of OCI were recorded. 

Results: OCI was not detected in 577 patients (96.3%) and was detected in 22 patients (3.7%). LSTV was not detected in 522 patients (87.2%) and was present in 77 patients (12.8%). The mean age of the patients who detected OCI was 30.7 years (+/- 9.5) while without OCI was 43.1 years (+/- 16.6) . 18 (81.8%) of the 22 OCI detected cases were female while 4 (18.2%) cases were male. OCI was more common in young people and female. LSTV was observed in 41 (16.2%) of the female patients while in 36 of the male patients (10.3%). LSTV was observed more frequently in female patients. There was no statistically significant difference between groups with and without OCI disease in terms of presence of LSVT. 

Conclusion: Both OCI and LSVT are situations that cause back pain. These two diagnoses must be taken into account in examinations made with lumbar pain cause.

Bel ağrısında nadir ve gözden kaçan iki tanı: Osteitis kondensans ilii ve lumbosakral transizyonel vertebra

Öz

Amaç: Bu çalışmada osteitis kondensans ilii (OKİ) ve lumbosakral transizyonel vertebranın (LSTV) sıklığı, bu iki durum arasında ilişki olup olmadığı ve bu durumların yaş ve cinsiyetler arasındaki değişkenliklerinin tespitini amaçladık.

Yöntemler: Ocak 2016 -Mart 2016 tarihleri arasında lomber bel ağrısı nedeni ile lomber bilgisayarlı tomografi (BT) çekilmiş 599 hastanın incelemeleri retrospektif olarak değerlendirildi. Bütün BT çekimleri 16 kesitli BT cihazında gerçekleştirildi. Her hasta için yaş, cinsiyet, LSTV anomalisi olup olmadığı bilgisi ve tipi (lumbalizasyon ve sakralizasyon) ile OKİ varlığı ile taraf bilgisi kaydedildi. 

Bulgular: Değerlendirilen hastaların 577’sinde (%96.3) OKİ saptanmazken 22’sinde (%3.7) saptandı. Değerlendirilen hastaların 522’sinde (%87.2) LSTV saptanmazken 77’sinde (%12.8) saptandı. OKİ saptanan hastaların ortalama yaşı 30.7 (+/- 9.5), saptanmayanlarınki 43.1 (+/- 16.6) yıl idi. OKİ saptanan hastaların 18’i (%81.8) kadın, 4’ü (%18.2) erkekti. OKİ kadın hastalarda ve genç yaş grubunda daha sıktı. LSTV kadın hastaların 41’inde (16.2%) erkek hastaların ise 36 ‘sında (10.3%) gözlendi. LSTV kadın hastalarda daha sık gözlendi. OKİ olan ve olmayan hasta grupları arasında LSTV varlığı ve yokluğu arasında istatiksel fark yoktu. 

Sonuç: Hem OKI hem de LSTV bel ağrısına neden olan durumlardır. Lomber bel ağrısı ile tetkik edilen hastalarda bu iki tanı dikkate alınmalı, akılda tutulmalıdır.
