Calcified thoracic herniation

BACKGROUND: Thoracic disc herniations (TDHs) are rare (0.15-4%) and often cause significant myelopathy (70-95%). They are defined as "Giant" if they occupy >40% of the spinal canal. Further, they are ossified/calcified in 42% of cases, with a 70% incidence of intradural extension. Here, we reviewed our experience resecting 24 giant thoracic discs utilizing a posterolateral surgical approach. METHODS: Over a 2-year period, we evaluated the outcomes for 24 patients averaging 40 years of age undergoing posterolateral resections of giant ossified/calcified TDH...

Thoracic disc herniation is one of the most therapeutically challenging spine conditions. A myriad of surgical approaches have been described in the literature, including posterior, anterior, and combined techniques. However, transthoracic and retropleural approaches are currently deemed the most effective techniques to successfully obtain anterior decompression. Herein the authors describe a 65-year-old female patient who underwent a transthoracic endoscopic approach to remove a calcified herniated thoracic disc that caused spinal cord compression...

Thoracic disc herniations can cause radiculopathy and myelopathy from neural compression. Surgical resection may require complex, morbid approaches. To avoid spinal cord retraction, wide exposures requiring extensive tissue, muscle, and bony disruption are needed, which may require instrumentation. Anterior approaches may require vascular surgeons, chest tube placement, and intensive care admission. Large, calcified discs or migrated fragments can pose additional challenges. Previous literature has noted the endoscopic approach to be contraindicated for calcified thoracic discs...

BACKGROUND: Thoracic disk herniation is rare and difficult to treat. The minimally invasive lateral retropleural approach to the thoracic spine enables the surgeon to decompress the neural elements and minimize thecal sac manipulation through direct visualization with less exposure-related morbidity. OBJECTIVE: To provide a detailed step-by-step overview of the minimally invasive retropleural approach for thoracic diskectomies, including preoperative planning through postoperative care as practiced at our institution...

OBJECTIVE: Thoracic myelopathy caused by severe anterior ossification is often progressive and fails to respond to conservative treatment. Removal of the compressing ossification is the most effective method but is hard to operate. In this study, we describe a novel one-stage posterior circumferential decompressive procedure assisted by an angled ultrasonic bone curette (UBC) for thoracic myelopathy caused by severe anterior ossification and evaluate its safety and efficacy. METHODS: The current study enrolled 15 consecutive patients (five men and 10 women) with thoracic myelopathy caused by severely anterior ossification between January 2017 and December 2019...

BACKGROUND: Giant thoracic disk herniations are calcified hernias that fill >40% of the spinal canal and result in myelopathy with associated neurologic symptoms. This is a fairly rare abnormality that requires surgical treatment. Currently, there is no unambiguous opinion about the surgical approach to the treatment for this pathology. It is believed that the most effective method is the anterior approach (minithoracotomy or thoracoscopic approach), which reduces the risks of spinal cord injury but is associated with the risks of damage to the lungs, pleura, and major vessels...

BACKGROUND: Foot drop is a syndrome resulting from weakness or paralysis of the tibialis anterior muscle. Some patients with thoracic disc herniation seek medical help complain of foot drop as the initial symptom. The study investigated the clinical characteristics of these patients and clarified the clinical efficacy after treatment. METHODS: A total of 13 patients with foot drop as the initial symptom arising from thoracic disc herniation were collected from January 2015 to December 2020...

PURPOSE: Giant thoracic disc herniations (GTDH) are considered a subgroup of TDHs with worse functional outcomes, a high calcification rate, and a considerable risk of complications. We aimed to determine whether there is a relationship between the extent of calcification of GTDH and outcomes concerning the risk of complications, the surgical technique, and changes in neuromonitoring signals. METHODS: We present a retrospective analysis of 76 patients undergoing surgery for calcific GTDH...

OBJECTIVE: To describe a cohort of T3-T4 thoracic disc herniations (TDHs), their clinical and radiologic characteristics, and unique thoracoscopic transaxillary approach (TAA). METHODS: All patients operated on for a T3-T4 TDH with minimal follow-up of 1 year were selected. RESULTS: Eight TAA procedures (6 males and 2 females) were included (1.4%). Six patients reported axial pain, irradiating in 2, 4 sensory changes, 1 objective and 1 merely subjective motor weakness...

PURPOSE: To report the safety and efficacy of posterolateral approach for thoracic disc herniation (TDH) via a consecutive clinical case series of 30 central thoracic disc herniations that were all operated through a posterolateral approach. METHODS: A retrospective review was conducted of all patients with symptomatic TDH who underwent surgical intervention from 2016 to 2021. A total of 23 patients comprising 30 central TDH were included in the study. Age, gender, location of the lesion, preoperative and post-operative Frankel and Nurick scores, surgical approach and instrumented vertebrae, and length of stay were recorded...

Thoracic disc herniation (TDH) is a rare occurrence comprising of only 0.25-0.75% of all herniated discs in any region. Limitations in direct visualization remains a surgical challenge for complete and safe resection of TDH. In this case report, we describe the use of a 3D intraoperative imaging system (O-arm system TM ) coupled with percutaneous pedicle markers placed under fluoroscopic guidance to circumvent the current limitations in visualisation for a patient with a giant calcified TDH using an anterolateral approach...

OBJECTIVE: Thoracic disc herniations (TDHs) are a challenging pathology. A variety of surgical techniques have been used to achieve spinal cord decompression. This series elucidates the versatility, efficacy, and safety of the partial transpedicular approach with the use of intraoperative ultrasound and ultrasonic aspiration for resection of TDHs of various sizes, locations, and consistencies. This technique can be deployed to safely remove all TDHs. METHODS: A retrospective review was performed of patients who underwent a thoracic discectomy via the partial transpedicular approach between January 2014 and December 2020 by a single surgeon...

In all levels of disc herniations the absolute surgical indications include deteriorating neurological deficits with myelopathy or cauda equina syndrome. However, this review summarized the relative indications for surgery in each level.In cervical disc herniation (CDH), the indications for surgery consist of six months of persisting symptoms, not responding to conservative treatment. However, high-quality studies are lacking, and a randomized controlled trial is now underway to clarify the indications.In thoracic disc herniation (TDH), the indications for surgery comprise failure of conservative measures and/or worsening neurological symptoms...

BACKGROUND: Thoracic myelopathy can have different aetiologies. Based on the location and on the nature of spinal cord compression, different surgical approaches may be indicated. METHOD: We present a rare case of thoracic myelopathy caused by the coexistence of a giant disc herniation, OPLL and OLF, and we describe the surgical approach, with a focus on technical nuances and strategies to avoid complications. CONCLUSION: Careful presurgical planning and microsurgery are fundamental in achieving a satisfactory spinal cord decompression...

BACKGROUND: The aim of this study was to evaluate the safety and long-term clinical outcomes of transforaminal full endoscopic discectomy and foraminotomy performed with manual reamers under local anesthesia on soft and calcified herniated discs in the mid and lower thoracic spine. METHODS: Postoperative pain relief was self-evaluated by 16 patients using a visual analog scale (VAS) and Oswestry Disability Index (ODI). Patients were scored at 6, 12, 24, and 60 months after surgery...

PURPOSE: Post-operative neurological deterioration (ND) is a severe complication. However, limited literature exists on the ND in thoracic disc disorders with myelopathy (TDM). This study describes the risk factors of neurological deterioration in TDM with instrumentation and fusion. METHODS: A single-centre review of TDM with instrumentation and fusion during 2006-2019 was performed. Post-operative neurological deterioration was defined as the deterioration of pre-existing neurological function or the appearance of new neurological symptoms...

This video depicts the removal of an intradural thoracic disc herniation through a purely transdural approach. Thoracic disc herniations are rare, and less than 5% are intradural. Though thoracic disc herniations are removed through a posterolateral or transthoracic corridor, there is literature to support a transdural approach for central herniations.1-3 Although the transdural approach has been selectively adopted for central soft herniations, calcified herniations have been regarded as less suitable.1,2 Intradural thoracic herniations have not been specifically addressed by a transdural approach in the limited literature, though it has been utilized in conjunction with a larger transthoracic approach...

STUDY DESIGN: Retrospective cohort study. OBJECTIVES: The treatment of giant thoracic disc herniation (gTDH)remains challenging for surgeons worldwide because of its large volume and calcified or ossified nature and the limitations of the prior small-sample-size, single-center studies reporting comparative effectiveness. We aim to compare the anterior decompression and spinal fusion (ASF) and posterior circumspinal decompression and spinal fusion (PCDF) for patients with myelopathy due to gTDH in the largest study to date by sample size...
