Chondrosarcoma is the second most common surgically treated primary bone sarcoma. Despite a large number of scientific papers in the literature, there is still significant controversy about diagnostics, treatment of the primary tumour, subtypes, and complications. Therefore, consensus on its day-to-day treatment decisions is needed. In January 2024, the Birmingham Orthopaedic Oncology Meeting (BOOM) attempted to gain global consensus from 300 delegates from over 50 countries. The meeting focused on these critical areas and aimed to generate consensus statements based on evidence amalgamation and expert opinion from diverse geographical regions. In parallel, periprosthetic joint infection (PJI) in oncological reconstructions poses unique challenges due to factors such as adjuvant treatments, large exposures, and the complexity of surgery. The meeting debated two-stage revisions, antibiotic prophylaxis, managing acute PJI in patients undergoing chemotherapy, and defining the best strategies for wound management and allograft reconstruction. The objectives of the meeting extended beyond resolving immediate controversies. It sought to foster global collaboration among specialists attending the meeting, and to encourage future research projects to address unsolved dilemmas. By highlighting areas of disagreement and promoting collaborative research endeavours, this initiative aims to enhance treatment standards and potentially improve outcomes for patients globally. This paper sets out some of the controversies and questions that were debated in the meeting.

Aims

We aimed to evaluate the long-term impact of fracture-related infection (FRI) on patients’ physical health and psychological wellbeing. For this purpose, quality of life after successful surgical treatment of FRIs of long bones was assessed.

Introduction. Critical limb ischemia (CLI) is the reduced blood flow in the arteries of the lower extremities. It is a serious form of peripheral arterial disease, or PAD. If left untreated the complications of CLI will result in amputation of affected limb. The treatment experience of diabetic foot with transverse tibial transport was carried out by Ilizarov technique. Madura foot ulcer is not a common condition. It disturbs the daily activities of the patient. Pain swelling with multiple nodules with discharging sinus with discoloration(blackening) of the affected area is the main problem. Materials and Methods. We treated total case: 36 from Jan. 2003 – Jan. 2020 (17yrs.). Among these-. TAO- 20. Limb Ishchemia- 5. Diabetic Foot- 9. Mycetoma pedis- 2. Infected sole and dorsum of the foot- 5. Results. Transverse corticotomy and wire technique followed by distraction increases blood circulation of the lower limbs, relieving the pain. The cases reported here were posted for amputation by the vascular surgeons, who did not have any other option for treatment. Hence we, re-affirm that Academician Prof. Ilizarov's method of treatment does help some patients suffering from these diseases. Conclusions. By Ilizarov compression distraction device for TAO, modura foot ulcer, diabetic foot ulcer, mycetoma pedis ulcer, infected sole and dorsum of the foot ulcer were treated by introducing K/wires through the bones with proper vertical corticotomy. Application of this noble device will bring angeogenesis within the reach of all deserving patients

Aims

Amputation in intractable cases of complex regional pain syndrome (CRPS) remains controversial.

The likelihood of recurrent Complex Regional Pain Syndrome (CRPS), residual and phantom limb pain and persistent disability after amputation is poorly described in the literature. The aims of this study were to compare pain, function, depression and quality of life between patients with intractable CRPS who underwent amputation and those in whom amputation was considered but not performed.

Endoprosthetic replacement following oncological conditions has shown to be at higher risk of sceptical complications due to the use of implants of unusual size, major soft tissue loss and immunsupression. 373 patients have been treated at our institution for malignant tumours of the bone or soft tissue around the knee with a modular tumour-prostheses of the knee joint since their availability from 1978. Infection or septic complications were identified in 78 patients (20.9%). In 15 cases of superficial wound healing disturbances with a fistula simple excision and revision of the wound was performed. In 48 cases of deep periprosthetic infections patients underwent one-stage revision with explantation of the total prosthetic material except femoral and tibial stems, extensive debridement of the wound and replantation of the disinfected prostheses throughout one operation. In 8 patients two-stage revision of the prostheses was performed, using an antibiotic impregnated cement spacer and Steinmann nails. In 5 patients amputation of the affected limb was indicated, whereas 2 patients could be treated conservatively. Out of the patients treated by one-stage revision 16 developed recurrent infection and had to undergo consecutive surgery. After two-stage surgery 4 patients showed signs of septic recurrence. According to our results deep periprosthetic infection of tumour-prostheses primarily can be treated by one-stage revision, in recurrent infections, however, two-stage revision should be performed. We additionally suggest the use of local or pedicled muscle flaps to obtain better soft tissue coverage of the prostheses after infection

Goals: Sarcomatous degeneration of giant cell tumours (GCT) occurs rarely. It occurs in less than 1% of the cases, and most of them are GCT previously treated with radiotherapy. The goal of this presentation is to review the CGT cases treated at our unit that have evolved towards malignization. Methods: Retrospective study of 96 GCT treated at our Hospital between 1983 and 2005. 5 presented sarcomatous degeneration in their evolution. These were the cases of 3 men and 2 women with a mean age of malignization of 42 years (32 years – 54 years). The median follow-up period was 155 months (5 months – 209 months). 3 cases affected the distal femur, one case affected distal radius and one case affected proximal humerus, with a slight tendency to the right hemibody. The primary treatment for GCT in these patients was curettage and bone graft. Only one case had received previous radiotherapy. In the same period of time we had two cases of lung dissemination of CGT with typical histology, without previous malignization of tumour. Results: Malignization takes place, on average, at the 1.8th recurrence (1.3). Histologically, we find 3 osteosarcomas and 2 indifferentiated tumours. Three patients developed distant dissemination; 2 patients died due to lung metastases, with a mean time between the first surgery and the sarcomatous degeneration of 90 months (40 monts – 183 months) and a mean time between malignization and mestastases of 22.3 months (9 months – 34 months) The treatment, once the malignization was diagnosed, consisted in wide resection and substitution with mega-arthroplasty in cases of distal femur and osteoarticular graft at the shoulder. 2 cases required amputation of the affected limb due to irresecable recurrence in soft tissues. Conclusions: There is no predictive criteria of which type of primary typical CGT will evolve into sarcoma. The malignization always has as a result high grade sarcomas, with a high tendency to hematogenous dissemination. When lung metastases appear the survival prognosis is a number of months. We must suspect malignization of a benign CGT when one of the relapses shows a very rapid growth with radiologic aggressive characteristics; in these cases we prefer wide resection of the tumour instead of curettage and thus we prevent the possible sarcomatous degeneration
