Purpose of the study

We report on the clinical, radiographic and functional outcomes after salvage arthrodesis for complex ankle and hindfoot problems the Portsmouth experience with the Ilizarov ring fixator.

Methods and results

We report on 10 patients who underwent ankle and hindfoot (tibio-calcaneal) arthrodeses using an Ilizarov ring fixator between 2006 and 2010. The indications included failed fusion after primary arthrodesis, sepsis complicating internal fixation of fractures, talar avascular necrosis and failed total ankle arthroplasty (TAR). All patients had undergone multiple previous surgeries which had failed. There were 7 males and 3 females in this group. Average age of the patients was 60 (47 years–77 years) Mean follow up was 32 months (6–56 months) BMP 2 (Inductos) was used in three cases. The procedure was combined with a proximal corticotomy and lengthening in 2 patients who had undergone a talectomy and tibio-calcaneal fusion. There were no major complications apart from minor pin site infections requiring oral antibiotics. There were no deep infections, thromo-embolic issues, CRPS, or functional problems on account of limb shortening.

Patients were assessed clinically, radiologically and using functional outcome scores EQ50 and AOFAS. Solid arthrodesis was achieved in all but one patient who was subsequently revised with a hindfoot nail. All patients were satisfied with their overall improvement in pain and function.

There is currently no standard follow up protocol for patients who have been diagnosed with and treated for high-grade osteosarcoma. We therefore investigated the possibility of creating a risk based follow-up protocol for patients with primary osteosarcomas.

313 patients diagnosed with primary osteosarcomas were studied. The identified risk factors for local recurrence included poor necrosis, inadequate margins and high risk tumour site in the bone. The risk factors for metastases were poor necrosis, inadequate margins, extra-compartmental stage and tumour size ≥5cm.

The risk of local recurrence and/or metastases within three years of diagnosis increases as the number of risk factors increase. Patients were grouped according to their number of risk factors. The cumulative risk of metastases for patients with 0, 1, 2, 3 and 4 risk factors is 0%, 12%, 21%, 54% and 60% respectively (p=<0.0001). Risk of local recurrence for patients with 0, 1, 2 and 3 risk factors is 5%, 14%, 25% and 20% respectively (p=0.0025).

Our investigation shows that by grouping patients together according to their number of identified risk factors, it is possible to identify groups of patients that are most at risk. This information can be used to design an evidence based follow up protocol which would have important implications for clinical practice.

Background: There is currently no standard follow up protocol for patients who have been diagnosed with and treated for high-grade osteosarcoma. We therefore investigated the possibility of creating a risk based follow-up protocol for patients with primary osteosarcomas.

Methods: 313 patients diagnosed with primary osteosar-comas were studied. The identified risk factors for local recurrence included poor necrosis, inadequate margins and high risk tumour site in the bone. The risk factors for metastases were poor necrosis, inadequate margins, extracompartmental stage and tumour size ≥5cm.

Results: The risk of local recurrence and/or metastases within three years of diagnosis increases as the number of risk factors increase. Patients were grouped according to their number of risk factors. The cumulative risk of metastases for patients with 0, 1, 2, 3 and 4 risk factors is 0%, 12%, 21%, 54% and 60% respectively (p=< 0.0001). Risk of local recurrence for patients with 0, 1, 2 and 3 risk factors is 5%, 14%, 25% and 20% respectively (p=0.0025).

Conclusion: Our investigation shows that by grouping patients together according to their number of identified risk factors, it is possible to identify groups of patients that are most at risk. This information can be used to design an evidence based follow up protocol which would have important implications for clinical practice.

Background & Methods: We reviewed the treatment of 311 patients with primary osteosarcoma treated at a specialist centre between 1995 and 2004. Of this number we identified 8 patients (2.5%) who had undergone inappropriate surgical treatment otherwise known as a ‘whoops’ procedure. These patients were studied to determine the impact of the whoops operations on their subsequent treatment and prognosis.

Results: The whoops procedure consisted of arthroscopic surgery in 3 patients, open reduction and internal fixation of pathological fractures in 2 patients, excision in 2 patients and curettage in 1 patient. The patients who had a whoops procedure were three times more likely to be male, older (median age 25 versus 16 years), had tumours in the lower extremities and were more likely to have amputation as primary local treatment (40% versus 25%). the rates of local recurrence and survival were similar in those with whoops procedures and without.

Conclusion: Whoops procedure is associated with increased risk of amputation and more extensive procedures but does not appear to affect the prognosis of the patient.
