Aims. The preoperative grading of chondrosarcomas of bone that accurately predicts surgical management is difficult for surgeons, radiologists, and pathologists. There are often discrepancies in grade between the initial biopsy and the final histology. Recent advances in the use of imaging methods have shown promise in the ability to predict the final grade. The most important clinical distinction is between grade 1 chondrosarcomas, which are amenable to curettage, and resection-grade chondrosarcomas (grade 2 and 3) which require en bloc resection. The aim of this study was to evaluate the use of a Radiological Aggressiveness Score (RAS) to predict the grade of primary chondrosarcomas in

Aims. The primary aim of this study was to determine the morbidity
of a tibial strut autograft and characterize the rate of bony union
following its use. Patients and Methods. We retrospectively assessed a series of 104 patients from a single
centre who were treated with a tibial strut autograft of > 5 cm
in length. A total of 30 had a segmental reconstruction with continuity
of bone, 27 had a segmental reconstruction without continuity of
bone, 29 had an arthrodesis and 18 had a nonunion. Donor-site morbidity
was defined as any event that required a modification of the postoperative
management. Union was assessed clinically and radiologically at
a median of 36 months (IQR, 14 to 74). Results. Donor-site morbidity occurred in four patients (4%; 95% confidence
interval (CI) 1 to 10). One patient had a stress fracture of the
tibia, which healed with a varus deformity, requiring an osteotomy.
Two patients required evacuation of a haematoma and one developed
anterior compartment syndrome which required fasciotomies. The cumulative probability
of union was 90% (95% CI 80 to 96) at five years. The type of reconstruction
(p = 0.018), continuity of bone (p = 0.006) and length of tibial
graft (p = 0.037) were associated with the time to union. Conclusion. The tibial strut autograft has a low risk of morbidity and provides
adequate bone stock for treating various defects of

The aim of this study was to assess the current trends in the estimation of survival and the preferred forms of treatment of pathological fractures among national and international general and oncological orthopaedic surgeons, and to explore whether improvements in the management of these patients could be identified in this way. All members of the Dutch Orthopaedic Society (DOS) and the European Musculoskeletal Oncology Society (EMSOS) were invited to complete a web-based questionnaire containing 12 cases.Aims
Materials and Methods
The management of chronic osteomyelitis requires the excision of necrotic and infected material followed by the prolonged administration of antibiotics. Sequestrectomy may be required before an involucrum has formed, resulting in a longitudinal bone defect. This can be difficult to fill. Vascularised grafts are complicated by a high rate of recurrent infection and thrombosis. We have managed defects of

To clarify the effectiveness of the induced membrane technique (IMT) using beta-tricalcium phosphate (β-TCP) for reconstruction of segmental bone defects by evaluating clinical and radiological outcomes, and the effect of defect size and operated site on surgical outcomes. A review of the medical records was conducted of consecutive 35 lower limbs (30 males and five females; median age 46 years (interquartile range (IQR) 40 to 61)) treated with IMT using β-TCP between 2014 and 2018. Lower Extremity Functional Score (LEFS) was examined preoperatively and at final follow-up to clarify patient-centered outcomes. Bone healing was assessed radiologically, and time from the second stage to bone healing was also evaluated. Patients were divided into ≥ 50 mm and < 50 mm defect groups and into femoral reconstruction, tibial reconstruction, and ankle arthrodesis groups.Aims
Methods
We report the outcome of 84 nonunions involving
long bones which were treated with rhBMP-7, in 84 patients (60 men:
24 women) with a mean age 46 years (18 to 81) between 2003 and 2011.
The patients had undergone a mean of three previous operations (one
to 11) for nonunion which had been present for a mean of 17 months
(4 months to 20 years). The nonunions involved the lower limb in
71 patients and the remainder involved the upper limb. A total of 30
nonunions were septic. Treatment was considered successful when
the nonunion healed without additional procedures. The relationship
between successful union and the time to union was investigated
and various factors including age and gender, the nature of the
nonunion (location, size, type, chronicity, previous procedures,
infection, the condition of the soft tissues) and type of index
procedure (revision of fixation, type of graft, amount of rhBMP-7) were
analysed. The improvement of the patients’ quality of life was estimated
using the Short Form (SF) 12 score. A total of 68 nonunions (80.9%) healed with no need for further
procedures at a mean of 5.4 months (3 to 10) post-operatively. Multivariate
logistic regression analysis of the factors affecting union suggested
that only infection significantly affected the rate of union
(p = 0.004).Time to union was only affected by the number of previous
failed procedures
(p = 0.006). An improvement of 79% and 32.2% in SF-12 physical and
mental score, respectively, was noted within the first post-operative
year. Rh-BMP-7 combined with bone grafts, enabled healing of the nonunion
and improved quality of life in about 80% of patients. Aseptic nonunions
were much more likely to unite than septic ones. The number of previous
failed operations significantly delayed the time to union. Cite this article:
Atypical cartilaginous tumours are usually treated
by curettage. The purpose of this study was to show that radiofrequency
ablation was an effective alternative treatment. We enrolled 20 patients (two male, 18 female, mean age 56 years
(36 to 72) in a proof-of-principle study. After inclusion, biopsy
and radiofrequency ablation were performed, followed three months
later by curettage and adjuvant phenolisation. The primary endpoint
was the proportional necrosis in the retrieved material. Secondary endpoints
were correlation with the findings on gadolinium enhanced MRI, functional
outcome and complications. Our results show that 95% to 100% necrosis was obtained in 14
of the 20 patients. MRI had a 91% sensitivity and 67% specificity
for detecting residual tumour after curettage. The mean functional
outcome (MSTS) score six weeks after radiofrequency ablation was
27.1 (23 to 30) compared with 18.1 (12 to 25) after curettage (p
<
0.001). No complications occurred after ablation, while two
patients developed a pathological fracture after curettage. We have shown that radiofrequency ablation is capable of completely
eradicating cartilaginous tumour cells in selective cases. MRI has
a 91% sensitivity for detecting any residual tumour. Radiofrequency
ablation can be performed on an outpatient basis allowing a rapid
return to normal activities. If it can be made more effective, it
has the potential to provide better local control, while improving
functional outcome. Cite this article:
