In 1999, we developed a technique for biological
reconstruction after excision of a bone tumour, which involved using
autografts of the bone containing the tumour treated with liquid
nitrogen. We have previously reported the use of this technique
in 28 patients at a mean follow up of 27 months (10 to 54). In this study, we included 72 patients who underwent reconstruction
using this technique. A total of 33 patients died and three were
lost to follow-up, at a mean of 23 months (2 to 56) post-operatively,
leaving 36 patients available for a assessment at a mean of 101
months 16 to 163) post-operatively. The methods of reconstruction included
an osteo-articular graft in 16, an intercalary in 13 and, a composite
graft with prosthesis in seven.
We reviewed the outcome of patients who had been
treated operatively for symptomatic peri-acetabular metastases and
present an algorithm to guide treatment. The records of 81 patients who had been treated operatively for
symptomatic peri-acetabular metastases between 1987 and 2010 were
identified. There were 27 men and 54 women with a mean age of 61
years (15 to 87). The diagnosis, size of lesion, degree of pelvic
continuity, type of reconstruction, World Health Organization performance
status, survival time, pain, mobility and complications including
implant failure were recorded in each case. The overall patient survivorship at five years was 5%. The longest
lived patient survived 16 years from the date of diagnosis. The
mean survival was 23 months (<
1 to 16 years) and the median
was 15 months. At follow-up 14 patients remained alive. Two cementoplasties
failed because of local disease progression. Three Harrington rods broke:
one patient needed a subsequent Girdlestone procedure. One ‘ice-cream
cone’ prosthesis dislocated and was subsequently revised without
further problems. We recommend the ‘ice-cream cone’ for pelvic discontinuity
and Harrington rod reconstruction for severe bone loss. Smaller
defects can be safely managed using standard revision hip techniques. Cite this article:
We set out to determine the impact of surgery on quality of life and function in patients who had undergone surgery for symptomatic peri-acetabular metastases. From a prospective database we retrospectively reviewed 46 consecutive patients who had been treated operatively between June 2003 and June 2009. The mean age of the patients was 56.4 years (20 to 73) and the mean post-operative follow-up was 19.2 months (4 to 70). Functional evaluation and quality-of-life assessments were performed. At the most recent follow-up, 26 patients (56.5%) were alive. Their median survival time was 25.0 months. Ten major postoperative complications had occurred in eight patients (17.4%). The mean post-operative Musculoskeletal Tumor Society score (MSTS 93) was 56.3% (6.7% to 90.0%). Improvement in the Eastern Cooperative Oncology Group (ECOG) performance status was seen in 32 patients (69.6%). On the European Organisation for Research and Treatment of Cancer core quality-of-life questionnaire (QLQ-C30) measure of global health status there was a statistically significant improvement from the patients’ pre-operative status (42.8 ( Surgery for patients with peri-acetabular metastases reduces pain and improves their quality of life, and has a low rate of surgical complications.
We reviewed nine patients at a mean period of 11 years (6 to 16) after curettage and cementing of a giant-cell tumour around the knee to determine if there were any long-term adverse effects on the cartilage. Plain radiography, MRI, delayed gadolinium-enhanced MRI of the cartilage and measurement of the serum level of cartilage oligomeric matrix protein were carried out. The functional outcome was evaluated using the Lysholm knee score. Each patient was physically active and had returned to their previous occupation. Most participated in recreational sports or exercise. The mean Lysholm knee score was 92 (83 to 100). Only one patient was found to have cartilage damage adjacent to the cement. This patient had a history of intra-articular fracture and local recurrence, leading to degenerative changes. Interpretation of the data obtained from delayed gadolinium-enhanced MRI of the cartilage was difficult, with variation in the T1 values which did not correlate with the clinical or radiological findings. We did not find it helpful in the early diagnosis of degeneration of cartilage. We also found no obvious correlation between the serum cartilage oligomeric matrix protein level and the radiological and MR findings, function, time after surgery and the age of the patient. In summary, we found no evidence that the long-term presence of cement close to the knee joint was associated with the development of degenerative osteoarthritis.
We retrospectively studied local recurrence of giant cell tumour in long bones following treatment with curettage and cementing in 137 patients. The median follow-up time was 60 months (3 to 166). A total of 19 patients (14%) had at least one local recurrence, the first was diagnosed at a median of 17 months (3 to 29) after treatment of the primary tumour. There were 13 patients with a total of 15 local recurrences who were successfully treated by further curettage and cementing. Two patients with a second local recurrence were consequently treated twice. At the last follow-up, at a median of 53 months (3 to 128) after the most recent operation, all patients were free from disease and had good function. We concluded that local recurrence of giant cell tumour after curettage and cementing in long bones can generally be successfully treated with further curettage and cementing, with only a minor risk of increased morbidity. This suggests that more extensive surgery for the primary tumour in an attempt to obtain wide margins is not the method of choice, since it leaves the patient with higher morbidity with no significant gain with respect to cure of the disease.
