الوصف: Trompeter, K, Weerts, J, Fett, D, Firouzabadi, A, Heinrich, K, Schmidt, H, Brüggemann, GP, and Platen, P. Spinal and pelvic kinematics during prolonged rowing on an ergometer vs. indoor tank rowing. J Strength Cond Res 35(9): 2622-2628, 2021-This investigation aimed to compare spinopelvic kinematics during rowing on an ergometer vs. in a rowing tank and to evaluate changes with progressing fatigue. Spinal and pelvic kinematics of 8 competitive scull rowers (19.0 ± 2.1 years, 179.9 ± 7.6 cm, and 74.8 ± 8.1 kg) were collected during 1 hour of rowing on an ergometer and in a rowing tank using a routine training protocol. Kinematics of the upper thoracic spine, lower thoracic spine, lumbar spine, and pelvis were determined using an infrared camera system (Vicon, Oxford, United Kingdom). There was a greater lumbar range of motion (ROM) and less posterior pelvic tilt at the catch during rowing on the ergometer compared with in the rowing tank (p = 0.001-0.048), but no differences in pelvic ROM. In the rowing tank, the pelvic ROM increased over time (p = 0.002) and the ROM of the lower thoracic spine decreased (p = 0.002). In addition, there was an extended drive phase (when the rower applies pressure to the oar levering the boat forward) and an abbreviated recovery phase (setting up the rower's body for the next stroke) in the rowing tank (p = 0.032). Different rowing training methods lead to differences in spinopelvic kinematics, which may lead to substantially different spinal loading situations. Greater pelvic rotation and lesser lumbar ROM are considered ideal; therefore, the present results indicate that rowing in the rowing tank might facilitate the maintenance of this targeted spinopelvic posture, which might help protect the lower back. Rowers, coaches, and researchers should consider the differences between rowing training methods, especially when giving training recommendations.

المصدر: Journal of Plastic, Reconstructive & Aesthetic Surgery. 74:2279-2282

الوصف: Limited data exist with regard to the outcome of the Nuss procedure for pectus excavatum repair in adults. Here, we analysed changes in lung capacity and thoracic morphology based on computed tomography (CT) imaging in adults with pectus excavatum before surgery, during bar insertion and after bar removal. Patients who underwent the Nuss procedure for pectus excavatum after the age of 20 were included in this study. Chest CT scans of the included participants were taken before the Nuss procedure, immediately before removal of the pectus bar and 6 months after removal of the pectus bar. Lung capacity and thoracic morphology measurements were made from the CT scans. Six patients aged 24-43 years were included in this study. After the Nuss procedure, lung capacity was decreased in all patients. Although the pectus bar was removed, lung capacity had not significantly increased and was almost the same volume as before the Nuss procedure. After the Nuss procedure, the funnel chest shape had improved in all cases, patients' thoracic spine had also moved forward as the thorax moved forward and patients' stoop had improved. Despite a lack of change in lung capacity, surgical modification should be considered to reduce stress on the thoracic spine and in turn, reduce pain in patients with pectus excavatum. However, further long-term observation seems necessary.

Neuromuscular Scoliosis

المؤلفون: Emily Kivlehan, Brian D Wishart

المصدر: Physical Medicine and Rehabilitation Clinics of North America. 32:547-556

الوصف: Scoliosis has a very high prevalence among patients with neuromuscular disease involving the thoracic spine and truncal muscles. Physical examination and radiographs are used to screen for presence of scoliosis and monitor progression. Management includes therapy participation, optimizing equipment and orthotic use, and possible surgical intervention. Unlike idiopathic adolescent scoliosis, curves tend to progress despite orthotic use compliance. Associated pelvic obliquity creates risk for pressure sores and pain. As such, education of caregivers is a key point of optimizing management.

Thoracic osteophyte as a cause of symptomatic greater splanchnic nerve compression. Case report

المؤلفون: J. Jankowski, M. Radek, A. Pawełczyk

المصدر: Neurochirurgie. 68:232-234

الوصف: Thoracic osteophytes are a common feature of degenerative spine disease. However, it is rare that osteophytes overgrowth on the anterior surface of thoracic spine results in the compression of vital structures and causes symptoms. A 39-year old man with a two-year history of thoracic and upper abdominal pain was admitted to the neurosurgery ward after having been seen by several specialists. Thoracic spine MRI and CT scans were analyzed. Osteophytes were identified on the anterolateral right side at level T8–T9 and were indicated as a possible cause of the symptoms. After obtaining patient consent, surgery was performed with transthoracic access to the anterolateral surface of the spine. Intraoperatively, the greater splanchnic nerve was released by osteophyte removal. The patient reported improvement of the preoperative symptoms at the six-month and two-year follow-up visit. Postoperative MRI indicated complete osteophyte excision. To the best of our knowledge, this is the first report of symptomatic sympathetic trunk branch compression by thoracic osteophytes.

Preparing for the Unexpected

المؤلفون: Roshni R Patel, A Orlando Ortiz, Michael Gottesman, Gregory Parnes

المصدر: Radiologic Clinics of North America. 59:511-523

الوصف: Potentially clinically important incidental/unexpected extraspinal findings occur with sufficient frequency in cross-sectional imaging of the spine to warrant the radiologist's careful consideration, regardless of whether the interpreter is a neuroradiologist, a musculoskeletal radiologist, an emergency radiologist, or a generalist. Awareness of the commonly encountered incidentalomas and the anatomy contained within the field of view of cervical, thoracic, and lumbar spine cross-sectional imaging examinations, respectively, assists radiologists in their efficient and accurate analysis. This article familiarizes radiologists with some of the potential relevant extraspinal findings that may be encountered, and recommends an extraspinal search pattern for each spinal segment.

Case Reports in Orthopedics

الوصف: Intraspinal extradural synovial cysts are a rare occurrence at the spinal cord level and thus a rare cause of myelopathy. Synovial cysts usually present in the more mobile lumbar and cervical parts of the spine; however, they may also arise in the thoracic spine. We present a case of a 59-year-old male with a left upper thoracic synovial cyst at T2-3 causing disabling, progressive myelopathy, and an incomplete spinal cord injury syndrome with inability to ambulate. An urgent decompressive laminectomy with bilateral facetectomies, cyst excision, and posterior fusion was performed. Subsequently, the patient recovered full function. Synovial cysts should be considered in the differential diagnosis of progressive thoracic myelopathy. This is only the sixth reported case of a synovial cyst of this kind occurring between the levels of T1 and T7. Urgent surgical decompression is the recommended treatment.

المؤلفون: Mohamed Kamal Mesregah, Jeffrey C. Wang, Carson Gardner, Sidney Roberts, Kishan Patel, Michael Repajic, Zorica Buser

المصدر: European Spine Journal. 30:2221-2230

الوصف: This study aimed to analyse the trends and patterns of IVD degeneration in different age groups at each level of the thoracic spine. This cross-sectional MRI study included 1000 symptomatic patients who had undergone upright thoracic spine MRI. A total of 13,000 thoracic IVDs from C7/T1 to T12/L1 were classified into five grades using Pfirrmann classification. Patients were divided according to their ages into five groups (n = 200/group). The severity and pattern of IVD degeneration were analysed in each age group. A predictive model of the severity and pattern of IVD degeneration in each age group was proposed. The total grade of IVD degeneration and the number of degenerated levels increased with increasing age (P

الوصف: Background Pathologies of the ventral thoracic spine represent a challenge, igniting arguments about which should be the ideal surgical approach to access this area. Anterior transthoracic thoracotomy and a number of posterolateral routes have been developed. Among the latter, costotransversectomy has demonstrated to provide good ventral exposure with a lower, but not negligible, morbidity. The optimal approach should be the one minimizing surgical morbidity on both neural and extraneural structures while optimizing exposure. Methods The authors described the combined, rib-sparing, bilateral approach (CRBA) to the ventral mid/low-thoracic spine. The technique combines a transfacet pedicle partially sparing approach on one side and a transpedicular with transverse process resection on the contralateral one. A laboratory investigation was conducted. The technique was applied in a surgical setting, and a case was reported. Results CRBA is rib-sparing, completely extracavitary, and does not require pleural exposure and paraspinal muscle splitting, thus minimizing potential morbidity. The combination of 2 corridors ensures the greatest exposure compared with standard posterolateral approaches. The only blind corner is limited to a small area just in front of the dural sac. A bimanual approach optimizes control during surgical manipulation, even if the area of maneuverability and cross-section areas of surgical corridors are slightly limited compared to traditional costotransversectomy due to the minimally invasive nature of the procedure. Conclusions CRBA represents a safe and effective option to access the ventral mid/low thoracic spine. It provides great exposure and bimanual manipulation of the surgical target, minimizes potential morbidity, and avoids entrance into the thoracic cavity and paraspinal muscle splitting.

Different disc characteristics between young elite skiers with diverse training histories revealed with a novel quantitative magnetic resonance imaging method

المؤلفون: Hanna Hebelka, Adad Baranto, Kerstin M. Lagerstrand

المصدر: European Spine Journal. 30:2082-2089

الوصف: Purpose To evaluate if there are differences in thoraco-lumbar disc characteristics between elite skiers and non-athletic controls as well as between different types of elite skiers, with diverse training histories, using a novel quantitative MRI method. Methods The thoraco-lumbar spine of 58 elite skiers (age = 18.2 ± 1.1 years, 30 males) and 26 normally active controls (age = 16.4 ± 0.6 years, 9 males) was examined using T2w-MRI. Disc characteristics were compared quantitatively between groups using histogram and regional image analyses to determine delta peak and T2-values in five sub-regions. Results A statistical difference in the delta peak value was found between skiers and controls (p p = 0.005), where skiers with highest training dose displayed less changes. Regional T2-value differences were found in skiers with divergent training histories (p Conclusion Differences in quantitative disc characteristics were found not only between elite skiers and non-athletic controls but also between subgroups of elite skiers with diverse training histories. The differences in the disc measures, reflecting tissue degradation, are likely related to type and intensity of the physical training. Future studies are encouraged to explore the relation between disc functionality, training history and pain to establish adequate prevention and rehabilitation programs.

Radiology Case Reports

الوصف: Hirayama disease is a cervical flexion myelopathy that typically causes upper extremity weakness in young male patients. We present two male patients (age 15 and 29) with MRI findings of thoracic ligamentous laxity similar in appearance to Hirayama disease. However, patients presented with atypical symptoms, specifically back pain and paresthesia of the upper and/or lower extremities, likely correlating to the abnormal thoracic spinal levels involved. Flexion/extension MRI sequences demonstrated the forward displacement of the dorsal dura and compression the thoracic cord with prominence of the posterior epidural space and venous plexus. Follow-up MRAs were negative for a spinal vascular malformation. Patients were managed conservatively with no surgical intervention. Clinical history, thoracic MRI, and follow-up flexion and angiographic imaging sequences may help confirm a diagnosis of Hirayama-like thoracic ligamentous laxity.
