“…The diagnostic pathway is indeed explainable, as symptomatic thoracic disc herniation is rare, accounting for only 0.25–0.57% of all disc herniation [ 24 ], and is more commonly above the level TH8 [ 24 ]. A further supplementary diagnostic method performed in this case was the EMG, showing signs of mono-segmental nerve root compression [ 11 ].…”

“…There are several possible surgical approaches to treat thoracic disc herniation, depending on localization, calcification of the herniated disc, and segmental instability. Posterolateral approaches are recommended for soft lateral disc herniation [ 8 ], and the transthoracic approach is more commonly used in large calcified central hernia [ 11 ]. Whether to stabilize or to perform a discectomy at all is currently a matter of debate [ 13 , 21 , 23 ].…”

“…Whether to stabilize or to perform a discectomy at all is currently a matter of debate [ 13 , 21 , 23 ]. Instrumented fusion can be required in cases performed from the posterior [ 11 ]. As our patient initially presented with an acute unilateral soft disc herniation without signs of segmental instability, we opted for a posterior approach with instrumentation.…”

We present a rare case of a patient initially presenting with unilateral abdominal wall bulging and radicular pain caused by a lateral disc herniation at Th11/12, later suffering from a hernia recurrence with bilateral disc prolapse and motor deficits. The patient underwent sequesterectomy via a right hemilaminectomy at Th11, and after 8 weeks, a bilateral sequesterectomy with semirigid fusion Th11/12 was performed. Unilateral motor deficits at the thoracic level have been discussed in case reports; a bilateral disc protrusion with abdominal wall bulging occurring as a recurrent disc herniation has never been described before.

Bu çalışmanın amacı lumbal spinal stenoz (LSS) tanısı konmuş bireylerde stenoz şiddetinin ağrı, günlük yaşam aktivitesi ve kas aktivasyonu üzerine etki edip etmediğini araştırmaktı. Gereç ve Yöntemler: Çalışmaya yaş ortalaması 55,19 ±10,41 (yıl) olan 48 LSS tanısı konmuş birey dahil edildi. Bireyler Manyetik Rezonans'da dural kese alanı incelenerek LSS şiddetlerine göre hafif, orta ve ağır olmak üzere 3 gruba ayrıldı. Bireylerin ağrı değerlendirmesi istirahat ve aktivite sırasında vizüel analog skala (VAS) ile, kas aktivasyonu değerlendirmesi Rektus Femoris, Biseps Femoris, Tibialis Anterior ve Gastroknemius kasının medial başından maksimum istemli kontraksiyon sırasında ve yürüme esnasında yüzeyel elektromiyografi (yEMG) ile, günlük yaşam aktivite yeterliliği Oswestry Bel Özürlülük İndeksi (ODI) ile ölçüldü. Bulgular: LSS şiddetine göre VAS ve ODI (hafif-orta stenoz, hafif-ağır stenoz, orta-ağır stenoz) parametrelerinde anlamlı farklılıklar bulundu (p<0.05). İstirahat ve aktivite sırasında yapılan ağrı ölçümleri birbirinden farklı idi (p<0.05). Ağır LSS'li bireylerin orta ve hafif LSS'li bireylere, orta LSS'li bireylerinde hafif olanlara göre alt ekstremite kas aktivasyonlarının daha fazla olduğu görüldü. (p<0.05). Sonuç: LSS şiddeti arttıkça kişilerin yetersizliklerinin ve ağrılarının arttığı, kas aktivasyonlarının yükseldiği saptandı. Hastaların aktifken daha çok ağrı hissettikleri tespit edildi. LSS erken teşhisin önemli olduğu ve şiddetinin artmaması için gerekli tedbirlerin alınması gerektiği sonucuna varıldı.

“…eoretically speaking, FMRI is designed to reflect the functional states of tissues and organs, and DTI, as an extension technique of conventional MRI, can visually display highly anisotropic nerve fibers [9]. On this basis, 3D MRI can process the cross-sectional images of any part or direction of one scan through electronic computers to form a 3D image, which can be further applied to diagnose the patient.…”

In this paper, the application of 3-dimensional (3D) functional magnetic resonance imaging (FMRI) in the diagnosis of the 5th lumbar (L5) nerve root compression and brain functional areas in patients with lumbar disc herniation (LDH) was analyzed. The traditional fast independent component analysis (Fast ICA) algorithm was optimized based on the modified whitening matrix to establish a new type of Modified-Fast ICA (M-Fast ICA) algorithm that was compared with the introduced traditional Fast ICA and ICA. M-Fast ICA was applied to the 3D FMRI diffusion tensor imaging (DTI) evaluation of 65 patients with L5 nerve root pain due to LDH (group A) and 50 healthy volunteers (group B). The values of fractional anisotropy (FA) and apparent diffusion coefficient (ADC) in the lumbar nerve roots (L3, L4, L5, and the 1st sacral vertebra (S1)) were recorded among subjects from the two groups. Besides, the score of edema degree in the lumbar nerve roots (L5 and S1) and activity of brain functional areas were also recorded among all subjects of the two groups. The results showed that the mean square error of M-Fast ICA was smaller than that of traditional Fast ICA and ICA, while its signal-to-noise ratio (SNR) was greater than that of Fast ICA and ICA ( P < 0.05 ). The FA of L5 and S1 nerve roots in patients of group A was sharply lower than the values of group B, while the ADC of patients in group A was greater than that of the control group ( P < 0.05 ). Besides, the score of edema in L5 and S1 nerve roots of patients in group A increased in contrast to group B ( P < 0.05 ). The brain areas were activated after surgery including bilateral temporal lobe, left thalamus, splenium of corpus callosum, and right internal capsule. In conclusion, the 3D image denoising performance of M-Fast ICA optimized and constructed in this study was superior to that of the traditional Fast ICA and ICA. The FA of patients with L5 nerve root pain due to LDH decreased steeply, while the ADC increased dramatically. L5 nerve root pain caused by LDH resulted in changes in brain functional areas of the patients to inhibit the resting state default network activity, and the corresponding brain functional areas could be activated through treatment.
