Chordomas are slowly growing, locally aggressive primary malignant neoplasms derived from primitive notochordal cells. They tend to occur at the extreme of ages and at the two ends of the spinal column. The purpose of this study was to evaluate the presentation, morphology and behaviour of 20 non-clival, non-sacral chordoma cases.

Details of 20 cases of histologically confirmed Chordomas of the mobile spine (Cervical-7, Thoracic-7, Lumbar-6) between 1967 and 2006, were extracted from the Scottish Bone Tumour Registry. The casenotes and radiographs were retrospectively reviewed.

Non-sacral chordomas comprised 48.7% (20/41 cases) of total chordomas registered. There was a slight feminine predominance (11/20 cases). Mean age was 58.1 years (range, 12 to 82 years). Progressively worsening back pain was the first symptom in all the patients. Seven had intra-lesional (five recurred), six marginal (1 recurred) and 2 wide resections (none recurred). Eleven of the twenty-one patients were treated with adjuvant radiation therapy. In five patients, the chordoma was inoperable and all but one were treated with radiotherapy. There were 2 recurrences in the group of patients treated without adjuvant radiotherapy.

Six patients (40%) developed local recurrences and 3 patients (15%) developed metastases. There were 4 survivors including one with local recurrence. Sixteen patients died including 3 with metastases, 7 with persistent primary disease, 1 with local recurrence and 5 with no evidence of disease or died of unrelated causes. Median survival was 19 months (mean-30.2 months), with 5- and 10-year survival rates 10% and 0.0% respectively.

We found that non-sacral/non-clival chordomas had a much poorer prognosis than published in the literature. Local recurrences occurred in 40%. Intra-lesional resection should be avoided as it is associated with 71.4% local recurrence in our series.

Chondrosarcomas are uncommon primary malignant cartilaginous tumours, even less common in spine. Surgical excision is the only mode of successful treatment as these tumours are resistant to conventional chemotherapy and radiation therapy. We share our experience of 22 cases of chondrosarcomas of the spine with special reference to their recurrence and survival.

We identified 20 conventional and 2 dedifferentiated chondrosarcomas from the Scottish Bone Tumour Registry database between 1964 and 2009. Radiology and histopathology were documented. The mean follow-up was 5.2 years.

There were 14 men and 8 women with a mean age of 50.1 years. There were 7 under the age of 40 years (31.8%). The majority of lesions occurred in the thoracic spine (16), followed by sacrum (3), lumbar (2) and cervical spine (1). The overall local recurrence rate was 45.4% (10/22 cases-once in 5, twice in 2 and thrice in 3 patients).

Four patients presented with pulmonary metastases leading to death. The estimated overall 5- and 10-year survival rates were 31.8% and 18.1% respectively. We found that 1/3^rd of chondrosarcomas of the spine occured below 40 years of age and 3/4^th in the thoracic spine. Every other case was associated with local recurrence with a 32% 5-year and 18% 10-year survival rates.

Sacro-coccygeal chordomas pose a difficult diagnostic and therapeutic problem due to late presentation, large size, soft-tisue extension, difficulties in obtaining adequate resection margins, higher local recurrence rate and uncertain effectiveness of adjuvant treatment. We present a series of 21 patients of sacral chordomas obtained from Scottish Bone Tumour Registry to analyse predictors of local control and survival.

The clinical and morphologic features, type of treatment and follow-up of 21 consecutive patients with sacral chordoma were retrospectively reviewed and analysed. The data were obtained from Scottish Bone Tumour Registry.

The average age at time of the biopsy was 59 years (range, 12 to 82 years): twelve patients were male and nine were female. Pain was the presenting symptom in all patients. Two had intralesional (both recurred), 9 marginal (4 recurred) and 3 wide resections (1 recurred). Fifteen of the twenty-one patients were treated with adjuvant radiation therapy. In seven patients, the chordoma was inoperable and all but one were treated with adjuvant radiotherapy. Local recurrence and metastases occurred in 7 (50%) and 5 (23.8%) patients. The 5-year and 10-year survival were 38% and 14.2%, respectively.

Excision of the lesion combined with adjuvant radiation therapy provided satisfactory results. Local recurrence presents a major problem in the management of sacral chordomas (50%). Intralesional resection should be avoided as it is associated with 100% local recurrence in our series.

Introduction: Current Literature is sparse with respect to the optimum surgical approach for fixation of a fractured neck of Femur. A cadaveric study has been performed to determine the pattern of innervation of the Vastus Lateralis muscle. Results indicate that a muscle splitting technique may cause more nerve damage than a muscle reflection technique. The purpose of this study was to determine the clinical and neurophysiological effects of two different surgical approaches to the proximal femur.

Methods: Patients were randomised to receive either a Vastus splitting approach or a Vastus reflecting approach to the fractured femoral neck. The contralateral leg was used as the control for neurophysiological investigation. Needle electromyography was performed on both the operated and unoperated limbs within 2 weeks of surgery.

Results: 25 patients were included in the study randomisation. A total of 17 patients completed neurophysiological investigation, 8 in muscle reflection and 9 in muscle splitting groups. There was a significant reduction in femoral nerve conduction velocity compared to the unoperated control side in the muscle split group. This was also the case for amplitude of response measured in the Vastus muscle. The muscle reflection group showed no significant differences in these parameters compared to the unoperated side.

Conclusion: On the basis of the results of this study we recommend a Vastus Lateralis reflecting approach for proximal Femoral fracture fixation. The functional outcome of a muscle splitting approach remains unclear but could be investigated as part of a larger trial.

Introduction: Giant cell tumours are locally highly aggressive and extremely unpredictable bone tumours. Treatment of spinal GCTs remains controversial. We report our experience of 11 Giant cell tumours of the spine identified from the Scottish Bone Tumour Registry.

Materials and Methods: Details of 11 cases of histologically confirmed Giant cell tumours of the spine (9 benign and 2 malignant) between 1960 and 2004, were extracted from the Scottish Bone Tumour Registry. The casenotes and radiographs were retrospectively reviewed.

Results: There was a slight feminine predominance of 7 cases. Mean age was 34 years (range, 16 to 61 years). The sacrum (5) was most common location, followed by lumbar (3), thoracic (2) and rarely in cervical (1). Operative intervention was carried out in 5 (curettage-1; excision-5). Three also received supplemented bone grafts. Radiotherapy (including some of the operative cases) was administered in 9 patients. There were 5 recurrences (45.4%). There were 7 survivors 2 of whom still had evidence of persistent primary disease. Two died with unrelated illnesses and two from local recurrences.

Conclusions: Axial GCTs behave aggressively with a high recurrence rate (45%). Radiotherapy is useful in the management of GCTs of the spine and conservative surgery with local radiotherapy is a viable treatment option in some selected patients.

Introduction: A retrospective analysis was performed to determine the oncological outcome of patients with Ewing’s sarcoma of the spine treated with combined chemotherapy and radiotherapy for definitive local control.

Materials and Methods: Fifteen patients were identified from the Scottish Bone Tumour Registry with a histologically confirmed Ewing’s sarcoma affecting the axial skeleton. All case notes and imaging were retrospectively reviewed.

Results: Primary vertebral Ewing’s sarcoma accounted for 8.3% of all malignant spinal lesions in our registry. The mean age was 17.8 years (between 4 and 39 years). There was a male predilection with 9 male and 6 female patients. Site was evenly distributed between cervical (4), dorsal (5) and lumbosacral (6) regions. Progressively worsening back pain was the first symptom in all the patients. Satisfactory imaging studies were available in all with plain radiographs (15), bone scan (11), CT-scan (12) and MR Scan (9) patients.

Biopsy was performed in 11 patients and surgical treatment was carried out in 3 patients including curettage (2) and excision with bone grafting (1). All patients were treated with adjuvant radiotherapy while 87% also received adjuvant chemotherapy. Seven patients were alive with no evidence of disease at a mean 6 year follow-up. Six patients died of metastatic disease, one due to local recurrence and one with persistent primary disease. The mean follow-up time was 65 months (median 28 months; ranging from 12 to 218 months).

Conclusions: Primary vertebral Ewing’s sarcoma comprised 8.3% of our National Registry’s primary malignant spinal lesions. Progressive vertebral pain in the late second decade and male gender should raise the suspicion of Ewing’s sarcoma. Ewing’s sarcoma of the spine treated with combined chemotherapy and radiotherapy for definitive local control achieved a 45% five year survival.

Introduction: Benign bone-forming tumours are common in children and adolescents. Careful radiographical and histological study is necessary to distinguish slow growing from more aggressive bone forming tumours. We reviewed 25 cases of primary benign bone forming tumours of the spine to investigate whether there were any obvious differences in their biological behaviour in adults compared to children.

Materials and Methods: Twenty five cases of primary benign bone forming tumours of the spine were identified from the Scottish Bone Tumour Registry: this data is collected prospectively. A retrospective review of this data was performed. There were 9 osteoid osteomas, 15 osteoblastomas and 1 aggressive osteoblastoma. These cases were divided into group A (children) and group B (adults).

Results: There were 16 patients in group A (6-osteoid osteoma, 9-osteoblastoma, 1-aggressive osteoblastoma), 10 boys and 6 girls. The mean age was 12.1 years (range, 6–16 years). There were 2 cervical, 4 thoracic, 8 lumbar and 2 sacral tumours. There were 9 patients in Group B (3-osteoid osteoma, 6-osteoblastoma), 7 boys and 2 girls. The mean age was 26.6 years (range, 18–53 years). There were 1 cervical, 6 thoracic, 2 lumbar and none sacral tumours.

Twenty two tumours were excised and 3 had curettage performed (1 child and 2 adults). There were 2 recurrences (one osteoid osteoma, one osteoblastoma), one from the excision group and one who had curettage, both in adults. These were successfully treated with re-excision. Mean follow-up was 8 years and all were alive at the time of final follow-up.

Conclusions: Benign bone forming tumours of the spine are extremely uncommon. In children they occur more commonly in lumbar spine, while thoracic involvement predominates in adult patients. Good outcomes are obtained with surgical treatment. Recurrence occurred only in the adult group: both of these patients had successful outcomes following further treatment.

Introduction: Only 4–13 % of all spine tumours are primary bone tumours. We report on 180 cases of primary malignant bone tumours of the spine from the Scottish Bone Tumour Registry. The aim of the study was to analyse the incidence, demography, pathology and survival patterns of primary malignant bone tumours of the vertebral column.

Materials and Methods: All of the data in the Scottish Bone Tumour Registry is compiled prospectively. This report is based on a retrospective review of all the data from 180 cases of primary malignant bone tumours (excluding metastatic lesions).

Results: Of 4,301 registry cases 4.1% were primary malignant lesions (n=180). Seventy two percent of all spinal tumours were primary malignant neoplasms. There were 22 cervical, 72 thoracic, 45 lumbar and 41 sacrococcygeal lesions. There was a male preponderance (103 males & 77 females). The mean age at presentation was 54 years (range, 4–86 years). The top two ranked tumours were myeloma (42) and chordoma (41). Ewing’ sarcoma (15), Leukaemik-Lymphomatous lesions (13), conventional osteosarcoma (10) and Paget’s sarcoma (9) followed thereafter.

The predominant presenting symptom was pain. Pathological fracture occurred in 7 patients. The operative treatment consisted of curettage (21), excision (51) and resection (9) with supplemented bone grafting (13). Adjuvant chemo (=61) and radiotherapy (=131) was also used in selective cases. Thirty patients were alive with no evidence of disease at a mean 5 year follow-up. Six were alive with persistent primary disease and/or local recurrence and/or metastases at the time of review. Eighty four patients died with persistent primary disease, 30 patients died of metastatic disease, 9 due to local recurrence and 17 of unrelated causes.

Conclusions: Only 4.1% of the musculoskeletal tumours were spinal: 40% involved the thoracic spine. Mean age at presentation was 54 years. Myeloma, chordoma, chondrosarcoma and Ewing’ sarcoma were the most common pathologies. Myeloma predominated: osteosarcoma was much less common in our series compared to previous reports. Early diagnoses resulted into improved outcome.

Osteoporosis and fragility fractures in men constitute a considerable burden in healthcare. We have reviewed 2035 men aged over 50 years with 2142 fractures to clarify the epidemiology of these injuries and their underlying risk factors. The prevalence of osteoporosis ranged between 17.5% in fractures of the ankle and 57.8% in those of the hip. The main risk factors associated with osteoporosis were smoking (47.4%), alcohol excess (36.2%), body mass index < 21 (12.8%) and a family history of osteoporosis (8.4%). Immobility, smoking, self-reported alcohol excess, a low body mass index, age ≥72 and loss in height were significantly more common among men with fractures of the hip than in those with fractures elsewhere.

Between 1944 to 2003, eighty nine cases were registered with a diagnosis of Paget’s sarcoma in the Scottish Bone and Soft Tissue Tumour Registry. We found thirteen cases of sarcomatous degeneration of the spine (0.26% of the total bone tumour registry case) which were analysed in this study elaborating clinical, radiological and histopathological features. The mean age was 66.9 years (range 56 to 79 years). There were ten males and three females. There were seven cases involving sacral spine (63.6%), three cases involving lumbar vertebrae and two affecting dorsal spine. One case had diffuse dorso-lumbar involvement from D11 to L3 vertebrae. The mode of presentation was increasing low back pain (in all 13), unilateral sciatica (6, left sided-5, right sided-1), bilateral sciatica (2), lower limb weakness (8) and autonomic dysfunction (4, presented as chronic cauda equina syndrome). The majority of the cases (69.23%) were osteosarcomas. Out of these osteosarcomas, two showed giant cell rich matrix and one revealed predominant telengiectatic areas. Rest of the histological types was shared by chondrosarcoma, fibrosarcoma and malignant fibrous histiocytoma. Decompression laminectomy was performed in three cases. Eight patients had received radiotherapy. The mean survival was 3.93 months (range, 1 week to 7 months), nearly half to the whole Scottish Paget’s sarcoma series with a mean survival of 7.5 months. We found a constellation of symptomatology due to radiculo-medullary compression with a fatal evolution, predominantly lumbosacral involvement, predominantly osteosarcomatous histopathology with a poorest prognosis of all Paget’s sarcoma. Although, decompression laminectomy and adjuvant radiotherapy provided reasonable pain relief and palliation; however, there was no significant influence on the overall prognosis of the patients with Paget’s sarcoma of spine in the last six decades.
