Abstract Although chrondrosarcomas are common primary bone tumors, their occurrence in the spine is very rare. Because total excision in such cases is seldom possible, few long term survivors have been reported. We are reporting one patient with a high thoracic spinal chondrosarcoma who survived with useful function for over 18 years because of repeated local tumor excisions. The literature is reviewed, and an aggressive surgical treatment of spinal chondrosarcoma is recommended.

A Prospective Study

Background. Osteoid osteoma (OO) is one of the most commonly occurring benign bone tumors. It constitutes 10-12% of benign bone tumors and 2-3% of primary bone tumors. In radiofrequency ablation (RFA) treatment, the cells of the tumor are thermally inactivated by the help of electrodes shaped like needles. In our study, we aimed to show the major and minor complications in patients undergoing RFA and to show what should be done to prevent these complications. Methods. The study was carried out as a prospective study on the follow-up of 87 osteoid osteoma patients treated between 2015 and 2017. The youngest of the patients was 1 year old and the oldest was 42 years old. The RFA procedure lasted 10 min on average, excluding anesthesia and preparation. All lesions were ablated at 90 degrees for 7 minutes with the heat increased gradually. All patients were followed up for 1 day in the orthopedics clinic. Results. Complications were observed in 7 patients. The lesions with the most complications were observed to be in the tibia, second-degree burns were seen in 2 patients, and superficial skin infection was observed in 2 patients. In 1 patient, the probe tip was broken and remained within the bone. Intramuscular hematoma was detected in 1 lesion located in the proximal femur. A complaint of numbness in the fingers developed in a lesion located in the metacarpus. Conclusion. Preventive measures should be taken before the procedure in order to prevent minor complications, and, for major complications, close follow-up should be done after the procedure and patients should be kept away from heavy physical activities for the first 3 months.

Intraosseous schwannomas represent an extremely rare subgroup of schwannomas, accounting for <1% of all primary bone tumors. They mostly occur in the mandible, the maxilla, the sacrum, and they are also seen in long bones. We herein report a rare presentation of an intraosseous schwannoma in the glenoid of a 49-year-old patient. She complained of shoulder pain and was referred to the orthopaedic oncologist after detection of a suspicious lesion on imaging. Biopsy revealed benign spindle cells and immunohistochemistry was positive for S100. Because of the rarity of these intraosseous schwannomas it is important to recognize their radiological and histological features and make a differential diagnosis with other lytic tumors. Only if these characteristics are recognized, correct treatment can be given with definite curettage and bone grafting and correct follow-up with avoidance of unnecessary adjuvant therapy.

Chondroblastoma is a rare tumor of bone that represents approximately 1% of all primary bone tumors. In the temporal bone, only 33 have been reported. We present a case of chondroblastoma of the temporal bone, followed by a literature review and analysis of reported cases. We conclude that the best chance for a prolonged disease-free interval is total excision using a combined otolaryngologic and neurosurgical approach.

Cumulative Probabilities

Abstract Introduction Extra-articular resection (EAR) of the hip joint is prone to significant complications and morbidity. Thus, this study evaluates the cumulative incidences and main reasons of reoperation following EAR of primary bone tumors of the hip to determine whether the outcomes are different between EAR of the pelvis and that of the proximal femur. Patients and methods Thirty-three patients presented with a PMBT of the proximal femur or pelvis were included in this study. Among all PMBTs, 58% originated from the pelvis and 42% were from the proximal femur. Twenty patients had chondrosarcomas (61%), 10 had osteosarcomas (30%), and 3 had sarcomas of another histological subtype (9%). Results The mean follow-up was of 76 months (range: 24–220 months). The cumulative probabilities of revision for any reason was 52% (95% confidence interval [CI]: 30%–70%) five years after surgery. The five-year cumulative probabilities of revision were 13% (95% CI: 4%–27%), 24% (95% CI: 10%–42%) and 34% (95% CI: 14%–56%) for mechanical, infectious and tumoral reasons, respectively. The five-year cumulative probabilities of revision for any reason were 78% (95% CI: 37%–94%) and 14% (95% CI: 2%–38%) for the pelvis and proximal femur, respectively ( p = 0.004). Posterior column preservation was significantly associated with more mechanical complications even after adjusting for the resection site ( p = 0.043). Conclusion Half of patients undergoing EAR of the hip joint for PMBT of the proximal femur or acetabulum will require another operation. EAR of the pelvis is associated with significantly worse outcome than EAR of the proximal femur.

Summary Background The aim of the study was to assess (1) sports activity, (2) sports involving the upper extremities, (3) functional outcome and (4) sports-related complications of long-term survivors of primary malignant bone tumors of the proximal humerus. Methods A total of 18 patients with an endoprosthetic reconstruction for primary malignant bone sarcoma of the proximal humerus (8 male, 10 female, mean age 19.9 ± 8.4 years, range 7.8–37.4 years) with an average follow-up of 18.1 ± 7.4 years (range 6.7–29.8 years) were included. The type of sport, frequency, duration of each sport session and the University of California, Los Angeles (UCLA) activity score were assessed before surgery, at 1 year, 3 years and at the latest follow-up. Functional outcome was assessed by the Toronto extremity salvage score (TESS). Results The mean UCLA activity score decreased from 8.0 (±1.3, range 5–9) preoperative to 4.2 (±1.7, range 3–8) at 1‑year follow-up (p < 0.05). After 3 years it increased to 5.1 (±1.75, range 3–8) and further to 7 (±1.8, range 4–9) at the last follow-up. The mean postoperative TESS was 80.8 (±6.4, range 75.7–91.4) at the latest follow-up. Patients who were initially more active without reconstruction including a synthetic mesh were more likely to develop soft tissue complications accompanied by proximal endoprothesis migration. Conclusion Patients with a modular endoprosthetic reconstruction of the humerus following primary bone sarcoma resume participation in sports. Regarding the low incidence of periprosthetic infections, utilization of a synthetic mesh for reconstruction to prevent soft tissue complications in active patients should be considered.

AbstractBackgroundDue to the rarity of primary bone tumors, precise radiologic diagnosis often requires an experienced musculoskeletal radiologist. In order to make the diagnosis more precise and to prevent the overlooking of potentially dangerous conditions, artificial intelligence has been continuously incorporated into medical practice in recent decades. This paper reviews some of the most promising systems developed, including those for diagnosis of primary and secondary bone tumors, breast, lung and colon neoplasms.ConclusionsAlthough there is still a shortage of long-term studies confirming its benefits, there is probably a considerable potential for further development of computer-based expert systems aiming at a more efficient diagnosis of bone and soft tissue tumors.

ABSTRACT Schwannoma originates from Schwann cells of peripheral nerve sheaths and account for 1% of benign primary bone tumors. The site most commonly involved is the mandible. We present a 47-year-old woman with schwannoma at mandible. Neurosensory examination comprised paresthesia at left side of the mandible. Radiologic examination showed a well-defined unilocular osteolytic lesion which located in the left side of the mandible. The lesion was surgically curetted. The patient is under our follow-up. In this report, clinical and histological features and treatment of the schwannoma are discussed. How to cite this article Simsek HO, Aksoy MC, Can C, Baykul T.

Whole-body scintigraphy with both 99mTc-phosphonate and 67Ga was performed on 92 patients suspected of primary bone tumors. In 46 patients with primary malignant bone tumors, scintigraphy with 99mTc-phosphonate disclosed the primary tumor in 44 cases and skeletal metastases in 11, and 67Ga scintigraphy detected the primary tumor in 43 cases, skeletal metastases in 6 cases and soft-tissue metastases in 8 cases. In 25 patients with secondary malignant bone tumors, bone scintigraphy visualized a single lesion in 10 cases and several lesions in 15 cases, and 67Ga scintigraphy detected the primary tumor in 17 cases, skeletal metastases in 17 cases and soft-tissue metastases in 9 cases. In 21 patients with benign bone disease positive uptake of 99mTc-phosphonate was recognized in 19 cases and uptake of 67Ga in 17 cases. It is concluded that bone scintigraphy should be used in patients suspected of primary bone tumors. If malignancy is suspected, 67Ga scintigraphy should be performed in addition.
