Background: Coccydynia is a painful condition of the sacrococcygeal region, with symptoms associated with sitting and rising from a seated position. It is frequently related to trauma and idiopathic causes, and the pain is mostly chronic. Percutaneous vertebroplasty and sacroplasty are the methods that are widely used for treating compression fractures and sacral insufficiency fractures, respectively. However, the success of polymethylmethacrylate injection in the treatment of osteoporotic coccyx fractures and coccydynia is still unknown. Case Report: A 68-year-old man was admitted to our clinic with complaints of pain in the sacrococcygeal and perianal regions. In the imaging studies, a fracture line in the fifth sacral and first coccygeal segments was observed as evidenced by a bony edema. Since the patient’s pain did not improve with conservative methods, we treated him with coccygeoplasty. No complication was encountered. The day after the operation, he was discharged from the hospital with complete pain relief. The patient confirmed having no pain on the third postoperative month and so did not need any analgesics. Conclusion: Coccyceoplasty may be a good treatment option for retractable pain in patients with acute or subacute osteoporotic coccygeal fractures and coccydinia with edema.

A 63-year-old man presented with a 4-month history of a slowly growing soft mass at his right parieto-occipital region. Neuroradiological examinations revealed an osteolytic extradural tumour of the skull vault. The outer and inner tables of the skull were partially destroyed by the tumour, but the dura was not involved. The tumour and the invaded bone were totally removed and the skull defect was reconstructed using the outer table of the adjacent intact skull. Histopathological examination confirmed plasmocytoma. Laboratory investigations revealed no systemic myelomatosis. It is very important to differentiate solitary plasmocytoma from systemic myelomatosis since their treatment and prognosis are different. Although the prognosis of solitary plasmocytoma is good, regular follow-up examinations are required for any possibility to progress to systemic myelomatosis.

OBJECTIVE: Spinal epidural fi brosis is commonly seen after laminectomy. There is not yet proven any agent preventing fi brosis in clinical usage. We used diclofenac sodium and diltiazem, which are fi brosis inhibitors. METHODS AND MATERIALS: 40 rats were divided into four groups of equal numbers: control, diclofenac sodium, diltiazem, and diclofenac sodium + diltiazem. Laminectomies were performed at L5 and L6. After a 4 week period, the rats were decapitated and the vertebral column blocks were removed for histopathologic examination. Fibrosis percentage, spread of fi brous regions, and fi broblast numbers were evaluated in each group and compared between the groups. RESULTS: The distribution of epidural fi brosis density, percentage of fi brosis, and distribution of fi broblasts in the diclofenac sodium + diltiazem group were signifi cantly lower than in the other groups. The fi broblast numbers of the diltiazem, and diclofenac sodium + diltiazem groups were signifi cantly lower than in the other groups. CONCLUSION: Diclofenac sodium + diltiazem used together provided better outcomes because each of them prevented fi brosis via different ways, probably through synergistic action (Tab.
