Idiopathic chondrolysis of the hip: a case report.

Idiopathic chondrolysis of the hip is a rare condition occurring mainly in adolescents and is characterised by a rapidly progressive destruction of the articular cartilage in the coxofemoral joint. Patients report intense pain, motion restriction and often limping due to shortening of the limb. The aetiology is not elucidated.

Early removal of a Maverick disc prosthesis: surgical findings and morphological changes.

We report the case of a patient who underwent explantation of a Maverick total disc prosthesis at the L5S1 level because of severe persisting pain one year after initial implantation. Dynamic radiographic imaging studies showed good position and size of the prosthesis and no evidence of loosening. Intraoperatively residual mobility at the proximal bone-prosthesis interface was detected, as well as gross metallosis around the articulation of the total disc prosthesis.

Treatment of high-grade spondylolisthesis by posterior lumbosacral transfixation with transdiscal screws: surgical technique and preliminary results in four cases.

In high-grade spondylolisthesis, the surgical treatment should be aimed at achieving good stability to allow solid fusion in the face of high biomechanical forces at the lumbosacral junction. A 360 degrees fusion seems to be able to provide this stability. This is however extensive surgery and many problems and complications have been reported.

Percutaneous plate fixation of fractures of the distal tibia.

Minimally invasive plate osteosynthesis (MIPO) of the distal tibia offers several theoretical advantages compared to classic open reduction and internal fixation. A mechanically stable fracture-bridging osteosynthesis can be obtained without significant dissection and surgical trauma to the bone and surrounding soft tissues. In this retrospective study we looked at the results and complications in ten consecutive patients treated with percutaneous plating for fractures of the distal tibia and plafond with a minimum follow-up period of one year.
