Pathological fractures after jaw cyst surgery are rare clinically but are a serious complication. Once a pathological fracture occurs, treatment time and economic costs increase, and doctors face difficulty in handling it. This article reports a case of a patient with mandibular pathological fractures after multiple odontogenic keratocyst surgery of the jaw. Mandibular lesions were located in the bilateral mandibular angles and had macrocystic changes. We adopted a conservative treatment plan, and the treatment effect was good. We also discussed and analyzed relevant literature to provide a reference for clinicians.

BACKGROUNDRecent studies have suggested that the presence of a pathological fracture does not impact on oncologic outcomes and the feasibility of limb salvage surgery (LSS) in appropriately selected patients when combined with neoadjuvant chemotherapy. These have largely been single institutional studies with limited numbers. The Eastern Asian Musculoskeletal Oncology Group reviewed the data from three large volume Asian orthopedic oncology centers to determine whether the presence of a pathologic fracture affected outcomes in osteosarcoma patients.

METHODSA retrospective review of the data was conducted. Ninety-five cases of nonmetastatic extremity osteosarcoma with a pathological fracture and 887 cases without fracture treated during the same period were compared.

RESULTSIn the fracture group, the LSS rate was 62.1%, and the rate of amputation was 37.9%. In the nonfracture group, the LSS rate was 74.7%, and the amputation was 25.3%. In patients with a pathologic fracture, the rate of local recurrence for LSS and amputation groups was 8.5% and 2.8%, respectively. In this group, the 5-year survival in the LSS group was 66% as against. 46.8% in the amputation group.

CONCLUSIONSOur study suggests that surgically treated patients with pathologic fractures in osteosarcoma have adequate local control and do not have a poorer outcome compared to patients without a fracture. Though osteosarcoma with a pathologic fracture is not a contraindication for limb salvage, appropriate case selection is important when deciding local control options to ensure adequate oncologic clearance.

PURPOSE: To analyze the results of surgical treatment for pathological fractures at the proximal femur. MATERIALS AND METHODS: Nineteen patients with a pathological fracture were included. The mean age was 65.7 years old. The patients comprised 8 males and 11 females. Primary tumors, types of pathological fractures, surgical procedures, and postoperative complications were recorded. Musculoskeletal Tumor Society (MSTS) functional score was used for functional evaluation. A Kaplan-Meier survival analysis was used to determine survival rate. RESULTS: The primary malignancies were 6 cases of breast cancer, 3 cases of lung cancer, 3 cases of renal cell carcinoma, 2 cases of cholangiocarcinoma, 2 cases of hepatocellular carcinoma, 1 case of esophageal cancer, 1 case of colon cancer, and 1 case of ovarian cancer. Pathological fractures included 8 cases of pertrochanteric fractures and 11 cases of subtrochanteric fractures. Intramedullary nailing was performed in 10 cases, and joint replacement surgery was performed in 9 cases. Postoperative complications included local recurrence in 1 case, infection in 1 case, and nail breakage in 1 case. The mean postoperative MSTS score was 21. The mean survival period was 10.6 months. Patient survival rates were 42.1% after 6 months, 26.3% after 12 months, and 10.5% after 24 months. CONCLUSION: Surgical treatment of pathological fractures at the proximal femur provided early ambulation, and excellent pain relief. The surgery was well tolerated emotionally. Surgery is necessary for improving the quality of life in such patients; however, more cases of pathological fractures in these regions should be subjected to detailed analysis.

Zoledronic acid has been used for prevention of osteolytic and osteoblastic bone metastasis. This case report illustrates an undesirable consequence from prolonged usage of zoledronic acid in bone metastasis prevention. Periprosthetic acetabular fracture in a patient treated with zoledronic acid for 7 years was reported. The clinical presentation, radiographic and pathological results were described. This is a rare complication after total hip arthroplasty which should not be ignored especially in patients who received long term bisphosphonate.

A young woman with severe vitamin D deficiency presented with proximal muscle weakness, fragility fracture and pseudoarthrosis. On evaluation, she was found to have hypercalcaemia, a single parathyroid adenoma and an undetectable 25-hydroxyvitamin D level. She received parenteral cholecalciferol and subsequently underwent curative parathyroidectomy. Postoperatively, she had hungry bone syndrome, which she gradually recovered from with calcium and calcitriol replacement. Notably, her calcium levels were in the lower limit of normal range and associated with elevated alkaline phosphatase levels at postoperative Day 14. Follow-up for the next four years showed that the patient had remarkable symptomatic and radiological improvements. In this report, we discuss the pathophysiological interactions between vitamin D deficiency and associated primary hyperparathyroidism.

BACKGROUND: We are presenting our experience in the use of locking compression plate (LCP) after juxta-articular oncological resections in addition to its use in pathologic fracture. METHODS: A retrospective audit of skeletal reconstruction using LCP in 25 cases of long bone tumors was performed from 2008 to 2010. Reconstruction following limb salvage surgery was done in 17 patients and internal fixation of pathological fracture was done in 8 patients. All patients were available for > 12 months of follow-up, and thus assessed for union at the resected ends. RESULTS: There were 8 males and 17 females in the study. The average age at the time of surgery was 30 years (range, 9 to 66 years). The minimum follow-up was 12 months (range, 12 to 32 months). All patients except three went on to heal successfully. Complications occurred in those three patients: wound infection in one, nonunion in another, and periprosthetic fracture in the other patient. In the remaining patients, union was achieved at an average of 6.5 months after reconstruction in curative resection and 4.75 months after fixation of pathological fractures. CONCLUSIONS: Joint sparing limb salvage surgery was made successfully possible after sekeletal reconstruction with LCP. Its use was also quite effective in pathological fractures with poor bone quality. Use of locking plates for musculoskeletal oncological reconstruction resulted in a good and predictable rate of union.
