Case ReportsRecurrent aggressive chondrosarcoma of the middle phalanx of the index finger: excision and reconstruction with an osteocartilaginous allograft.
Chondrosarcomas are malignant tumours and need to be treated aggressively including ablative surgery. Bovée et al. and Mankin have recently drawn attention to a less aggressive behaviour of chondrosarcomas of the phalanges compared with those of other localizations including the metacarpals. ⋯ The potential for systemic disease of chondrosarcomas of the phalanges is probably much lower than in chondrosarcomas of other localizations, and therefore digit-sparing techniques may be considered rather than ablative procedures.

Articulated distraction of the hip joint in the treatment of benign aggressive tumors located around the hip joint.
The proximal femur and acetabulum are frequent sites for benign active and aggressive lesions. The risk of pathologic fracture is great when a bone-destroying pathology involves an anatomic location such as the hip joint that undergoes profound mechanical loading. If the destruction involves a large area around the joint, secure fixation cannot be achieved with internal fixation implants. The study investigates use of articulated hip distraction to protect reconstructions performed for the treatment of benign active or aggressive tumors presenting with pathologic fracture. ⋯ According to the authors' knowledge, this investigation is the first in the literature describing the use of articulated joint distraction in the treatment of benign active and aggressive lesions around the hip joint. The procedure adopts principles of joint distraction into bone tumor surgery.

Influence of diclofenac (group of nonsteroidal anti-inflammatory drugs) on fracture healing.
Nonsteroidal antirheumatics (NSAR; NSAID) are often used in patients with fractured bones for analgetic reasons. This animal experiment was performed to determine the influence of NSAR on the process of fracture healing. As an alternative, tramadol, the centrally acting analgetic without peripheral effects, was included in this experiment. ⋯ Oral application of diclofenac significantly delayed fracture healing in rats. This effect might be comparable to other NSAR and fracture healing in humans.

Complications after pelvic sarcoma surgery are frequent; however, the reports on complications are limited. Results of the authors' experience with 110 primary pelvic tumor resections and methods to achieve low complication rates for pelvic reconstruction are reported. ⋯ Because of the small number of complications and good function, autograft implantation after iliac resection and hip transposition after acetabular resection are advisable.

Comparative StudyA comparative clinical outcome evaluation of smooth (10-13 year results) versus rough surface finish (5-8 year results) in an otherwise identically designed cemented titanium alloy stem.
We retrospectively compared the influence of surface finish with respect to the long-term durability of a cemented titanium alloy stem of the same design but different surface finish. ⋯ The implantation of titanium alloy stems with a rough surface finish cannot be recommended because of its high aseptic loosening rate.
