1. Coccygeal pain in a young man, persisting for ten years in all and for seven years after partial removal of the coccyx, was shown to be due to an intrathecal
Aims. We aimed to examine the long-term mechanical survivorship, describe the modes of all-cause failure, and identify risk factors for mechanical failure of all-polyethylene tibial components in endoprosthetic reconstruction. Methods. This is a retrospective database review of consecutive endoprosthetic reconstructions performed for oncological indications between 1980 and 2019. Patients with all-polyethylene tibial components were isolated and analyzed for revision for mechanical failure. Outcomes included survival of the all-polyethylene tibial component, revision surgery categorized according to the Henderson Failure Mode Classification, and complications and functional outcome, as assessed by the Musculoskeletal
We have carried out prosthetic reconstruction in six patients with malignant or aggressively benign bone tumours of the distal tibia or fibula. The diagnoses were osteosarcoma in four patients, parosteal osteosarcoma in one and recurrent giant-cell
Several techniques have been described to reconstruct a mobile wrist joint after resection of the distal radius for
The aim of this study was to analyse the gait

replacement of the proximal tibia for
We investigated whether the presence of a pathological
fracture increased the risk of local recurrence in patients with

Resection of a primary sarcoma of the diaphysis
of a long bone creates a large defect. The biological options for reconstruction
include the use of a vascularised and non-vascularised fibular autograft. The purpose of the present study was to compare these methods
of reconstruction. Between 1985 and 2007, 53 patients (26 male and 27 female) underwent
biological reconstruction of a diaphyseal defect after resection
of a primary sarcoma. Their mean age was 20.7 years (3.6 to 62.4).
Of these, 26 (49 %) had a vascularised and 27 (51 %) a non-vascularised
fibular autograft. Either method could have been used for any patient in
the study. The mean follow-up was 52 months (12 to 259). Oncological,
surgical and functional outcome were evaluated. Kaplan–Meier analysis
was performed for graft survival with major complication as the
end point. At final follow-up, eight patients had died of disease. Primary
union was achieved in 40 patients (75%); 22 (42%) with a vascularised
fibular autograft and 18 (34%) a non-vascularised (p = 0.167). A
total of 32 patients (60%) required revision surgery. Kaplan–Meier
analysis revealed a mean survival without complication of 36 months
(0.06 to 107.3, . sd. 9) for the vascularised group and 88
months (0.33 to 163.9, . sd. 16) for the non-vascularised
group (p = 0.035). . Both groups seem to be reliable biological methods of reconstructing
a diaphyseal bone defect. Vascularised autografts require more revisions
mainly due to problems with wound healing in distal sites of

Previous studies have shown that the activity of the cytostatic drug methotrexate (MTX) embedded in acrylic cement is not affected by thermal changes in the cement. MTX is slowly released from the cement for several months and remains biologically active throughout this period. Our aim was to determine whether MTX embedded in cement would control the local growth of a
