“…This is in common with other studies. Only in rare cases do IMMs occur on the trunk or other parts of the body [ 13 , 14 ]. Furthermore, our patient population showed a tendency towards being overweight.…”

Intramuscular myxomas (IMMs) are benign tumors. Evidence regarding diagnostic and therapeutic pathways is rare, and guidelines do not exist due to their low incidence. The aim of this study was a retrospective analysis at a university cancer center and the interdisciplinary re-evaluation of the individual diagnostic and therapeutic procedures. Overall, 38 patients were included in the study. IMMs occurred mostly in middle-aged women. At the time of first consultation, 57.9% had few symptoms or were asymptomatic. In 92.1% of the cases, the tumor was localized in the extremities. The lower extremity was affected in 73.7%. The average size of IMMs was 5.0 cm. The proximally located tumors in the gluteus, thighs, and upper arms were significantly larger (p = 0.02) than the distally-located tumors in the forearms and lower legs. An MRI was performed in 97.4%. Based on imaging, an IMM was suspected in 5.6% by radiologists and in 54.1% by musculoskeletal surgeons. An incision biopsy was performed in 68.4% and led in 100.0% to the right histopathological diagnosis. In total, 89.5% of IMMs were resected. Postoperative complications requiring revision occurred in 8.8%. Recurrences or degenerations of IMMs were not reported in any of these cases.

“…However, CSD surgery has a variety of approaches (anterior approach, posterior approach, simultaneous anteriorposterior approach, and 540° approach) because of the surrounding neurovascular structures, so expressing surgical grade of CSD surgery could be rather complicated. 15,19,20,[22][23][24]30 Recently, a classification system has been developed to standardize the description of cervical osteotomy types. 3 This system is a 7-point scale based on anatomical resections that are graded according to the potential for destabilization.…”

“…In addition, most of thoracolumbar spine deformity can be treated by the posterior only surgery, so it could be simple to express the surgical grade of thoracolumbar deformity. However, CSD surgery has a variety of approaches (anterior approach, posterior approach, simultaneous anteriorposterior approach, and 540° approach) because of the surrounding neurovascular structures, so expressing surgical grade of CSD surgery could be rather complicated [ 15 , 19 , 20 , 22 - 24 , 30 ].…”

“…However, surgical correction of CSD can be challenging not only because it often requires osteotomies to obtain adequate correction especially in the setting of rigid CSD, but also because the target of surgical correction is adjacent to the critical neurovascular structures. 8,[10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26] Thus, the postoperative complications have been reported to be relatively high and the number of studies on CSD are far inferior to those of thoracolumbar deformity.…”

Although cervical spinal deformity (CSD) can have a profoundly negative impact on an individual's quality of life and there have been many advances in surgical treatment of CSD in recent years, there exists no comprehensive classification system of surgical treatment that categorizes anterior and posterior surgery separately according to the grade of surgery. The objective of this study is to introduce the new classification system of various surgical treatments for CSD. We developed a new classification system (SOF system) for CSD surgery that describes the sequence of surgical approach (S), the grade of osteotomy (O), and the information of fixation (F) using alphanumeric codes. This new classification system can provide a consistent description of the various osteotomies performed in CSD surgery. Especially, regarding research, there has been a clear benefit to this classification. Having a standardized classification that allows for common frame for cervical deformity correction surgery, communication between surgeons and the evaluation of the CSD surgeries make it possible to conduct global comparative research about surgical outcome.

“…Intramuscular myxomas are a rare cause of low back pain that occur with a frequency of 1 in a million patients. [ 7 , 9 ] They are benign masses of mesenchymal origin composed of fibroblasts which lose the ability to produce mature collagen. [ 3 , 7 ] They occur most commonly in the heart and bony tissues (i.e., mandible and the maxilla), but rarely in the large skeletal muscles.…”

Background: With an estimated incidence of about 1 case/million patients, paravertebral intramuscular myxomas represent a rare cause of lumbar pain. Rather, they typically occur in the heart and in bone tissues. Case Description: A 64-year-old female presented with a protracted course of nocturnal lumbar pain that radiated to the anterior aspect of the right thigh accompanied by numbness. She reported a slow-growing right paramedian lumbar mass in the previous months. The magnetic resonance (MR) showed a right lumbar paravertebral intramuscular mass at the L3 level (i.e., 70 × 50 mm) that had well-defined margins, and markedly enhanced with gadolinium. Following gross total “en bloc” tumor resection, the patient fully recovered. Pathologically, the myofibroblastic lesion proved to be an intramuscular myxoma without malignant changes. Conclusion: A 64-year-old female presented with a slow-growing MR-documented right paramedian lumbar L3 mass responsible for proximal right-thigh numbness. Following “en bloc” gross total removal of the benign intramuscular myxoma, the patient was asymptomatic.
