  • 12. Review Literature – Incidence & Site• Thoracic disc herniation accounts for 0.15-4.4% of all disc herniations.• 75 % of all thoracic disc problems occur below T8, with a peak of 26% at T11-12.• The upper thoracic spine (T1-5) is the region least often affected, with only 6% of all thoracic disc herniations occurring here.• To date, a total of 31 cases of T1-2 disc herniation have been reported in the literature and all but one of these was diagnosed by myelography, computed tomography (CT), or CT myelography. Posterior surgical approaches were performed in all except one case, in which an anterior approach was used. Magnetic Resonance Image Findings and Surgical Considerations in T1-2 Disc Herniation H. Caner, B.F. Kilinçoglu, S. Benli, N. Altinörs, M. Bavbek; Can. J. Neurol. Sci. 2003; 30: 152-154
  • 13. Clinical presentation• Upper thoracic disc herniation is rare. Patients can easily be misdiagnosed with cervical disc herniation or thoracic outlet syndrome.• The common complaints in cases of this type are pain in the arm, shoulder, and neck (60%), as well as sensory (23%) and motor changes (18%).• Radiculopathy is the most frequent finding (87%) in published cases, and Horner.s syndrome is seen in 21% of patients.• Cervical MRI extended to include the upper thoracic region is diagnostic.
  • 14. Brown CW, Deffer PA Jr, Akmakjian J, et al:The natural history of thoracic disc herniation.Spine 17(Suppl):S97–S102, 1992• Brown, et al.,6 retrospectively reviewed data obtained in 55 patients with 72 thoracic disc herniations.• They found that 15 (27%) of these patients eventually required surgery, especially if they presented with signs of myelopathy.• The vast majority of patients, however, did not require surgery and have continued to perform activities of daily living, including vigorous sports activities.• There was no correlation between radiographic depiction and the patient’s symptoms.
  • 15. operative treatment of thoracic discs • Posterior approach - transpedicular, transfacet; • Posterolateral approach modified costotransversectomy, lateral extracavitary; • Anterolateral approach - transthoracic; • Thoracoscopic approachThoracic herniated disc surgery is reserved for cases ofmyelopathy, progressive lower extremity weakness, andintolerable radicular pain that does not get better withnon-surgical treatments.
  • 16. operative treatment of thoracic discs• Sharan et al reported that anterior discectomy without sternotomy.• Rossitti et al reported an approach - anterior discectomy with sternotomy.• Total disc excision is not possible when posterior or posterolateral approaches are used.• posterior approaches, including laminectomy with foraminotomies, laminectomy with transdural disc excision, and thoracotomy with lateral extracavitary exposure.
  • 17. Disc herniation at T1–2Report of four cases and literature reviewHoward Morgan, M.D., M.A., and Christopher Abood, M.D.Journal of Neurosurgery; January 1998 / Vol. 88 / No. 1 / Pages 148-150• Intervertebral thoracic disc herniations are uncommon and high thoracic disc herniations are rare. In the upper third of the thoracic spine, T1–2 is the most common level for disc ruptures.• In reviewing the literature on thoracic disc herniation, the authors found 27 cases at the T1–2 level, 23 of which were lateral disc herniations that produced radiculopathy and four of which were central disc herniations that caused myelopathy.
  • 18. The anterior approach to high thoracic (T1-T2) disc herniation; 1993, Vol. 7, No. 2 , Pages 189-192. By - Sandro Rossitti, Hannes Stephensen, Sven Ekholm and Claes Von Essen• A patient with a T1-T2 disc herniation, operated on via the anterior approach, is presented. In a search of the literature we found 18 reported cases, all operated on by posterior or posterolateral approaches. The feasibility of the anterior discectomy in our case was established by preoperative magnetic resonance imaging of the upper thorax. We think that an anterior discectomy at the level of the upper thoracic spine can be easily performed in selected cases. The clinical picture of T1 root compression is described.
  • 19. Neurologic manifestations of compressive radiculopathy of the first thoracic root Kerry H. Levin, MD From the Department of NeurologyCleveland Clinic Foundation, Cleveland, OH. • Neurologic deficits in the first thoracic (T1) root distribution are uncommon and not easily defined. Myotomal charts indicate that distal arm and hand muscles receive significant contributions from both the C8 and T1 roots. • A patient with focal T1 radiculopathy is presented who demonstrated motor axon loss isolated to the abductor pollicis brevis muscle. This finding provides another source of evidence that the abductor pollicis brevis is the primary T1 motor structure in the upper extremity, improving precision in clinical and electromyographic diagnosis.
  • 20. Disc herniation at T1–2Report of four cases and literature reviewHoward Morgan, M.D., M.A., and Christopher Abood, M.D.Journal of Neurosurgery; January 1998 / Vol. 88 / No. 1 / Pages 148-150• The T-1 radiculopathy usually involves weakness of the intrinsic muscles of the hand.• The motor deficit of C-8 radiculopathy involves the intrinsic muscles of the hand and most of the flexors and extensors of the fingers and wrist.• The T-1 radiculopathy may produce Horners syndrome (oculosympathetic paralysis) and diminished sensation in the axilla, which are not found with C-8 radiculopathy.• In clinical presentation as well as in treatment, the lateral T1–2 disc herniation resembles a cervical disc herniation, whereas the central T1–2 disc herniation displays the usual appearance of a thoracic disc herniation.
  • 21. High thoracic disc herniation. (PMID:3762895)Alberico AM, Sahni KS, Hall JA Jr, Young HFNeurosurgery [1986, 19(3):449-451]• A case of T-1, T-2 disc herniation is reported. The patient presented with diminished hand strength, medial arm and shoulder pain, and medial arm, forearm, and hand paresthesias.• After surgical decompression and removal of a disc fragment, the patient made a complete recovery.• Routine cervical myelography was considered inadequate in view of this patients symptoms. High thoracic myelography followed by computed tomographic scanning should be considered for patients with this presentation.
  • 22. Thoracic intervertebral disc herniations: diagnostic value of magnetic resonance imaging. (PMID:3173662) Blumenkopf BDepartment of Neurological Surgery, Vanderbilt University, Nashville, Tennessee. Neurosurgery[1988, 23(1):36-40]Thoracic disc herniation is relatively rare and frequentlyposes a challenge in clinical diagnosis. These protrusionshave been categorized into two major anatomical typesand three main clinical syndromes. A number ofcharacteristic radiographic features have been reported.Recently, magnetic resonance imaging (MRI) has gainedpopularity as a neurodiagnostic imaging tool.A series of nine cases of thoracic intervertebral discherniation is reported. The clinical aspects of the casesare discussed, and the potential value of spine MRI forthoracic disc herniation diagnosis is emphasized.
  • 23. Eur Spine J. 1995;4(6):366-7.First thoracic disc herniation with myelopathy.Nakahara S, Sato T.Department of Orthopaedic Surgery, Okayama UniversityMedical School, Japan.• The case of a patient with progressive paraparesis due to first thoracic disc herniation is reported. He was treated successfully with anterior interbody fusion by the Smith-Robinson approach.• An anterior approach is desirable for surgical treatment of T1/2 disc herniation, and up to this level the Smith-Robinson approach, without thoracotomy, is entirely possible.
