[Oblong acetabular cup, type TC, for revision total hip arthroplasty].
Revision total hip arthroplasty is a demanding surgical procedure. It involves a massive loss of acetabular bone stock associated with primary implant removal, and a complicated revision cup fixation in the highly damaged surrounding bone. The authors describe the use of a novel oblong acetabular cup, type TC (Trč-Cingr), for replacement of a loose acetabular component. The aim of the study is to present this novel implant with evaluation of the first clinical results and to report on the authors' experience with revision arthroplasty assessed at 24 to 62 months of follow-up. ⋯ The results show good applicability of the oval-shaped implant which is easy to implant, maintains good primary fixation and allows for good bone remodelling in its vicinity.

[ProDisc-C Total Disc Replacement. A four-year prospective monocentric study].
To present the results of an independent prospective monocentric study of patients with ProDisc-C Total Disc Replacement (CTDR) followed up for 4 years, and to analyse the most frequent late complications, in particular heterotopic ossification. ⋯ Heterotopic ossification is the most frequent late complication of total disc replacement. Many factors may be responsible for its development and therefore its prevention is not clear. The correct indication and appropriate surgical technique are most often recommended, and are considered also by the authors to be most important. Restricted motion at the treated segment/s has no significant effect on the patient's clinical status.

[Treatment of sequelae after Monteggia lesions in childhood].
To review the current methods of operative management of post-traumatic chronic radial head dislocation in chronic Monteggia lesions in children. ⋯ The operative treatment of consequences after Monteggia fractures in children has a relatively high rate of complications and unpredictable results. Indications for reconstruction involve a normal articular surface of the radial head and a normal alignment of the radius and ulna. Key words: Monteggia fracture, consequences, reconstruction surgery, childhood.

[Percutaneous dynamic interspinous stabilisation for the treatment of juxtafacet cysts of the lumbar spine: prospective study].
To present the authors' philosophy on the surgical treatment of juxtafacet cysts of the lumbosacral (LS) spine, with its primary aim of dynamic lumbar stabilisation with an interspinous implant, inserted by a minimally invasive approach, without concurrent exploration of the spinal canal and cyst removal. ⋯ 1. The original method of treating juxtafacet cysts of the LS spine by an In-Space interspinous spacer, as presented here, was efficient in all patients and resulted in complete, or at least partial, resorption of the cyst. 2. Segmental mobility and spondyloarthritis are the major aetiological factors of juxtafacet cyst development. 3. Dynamic interspinous stabilisation will reduce loading of the intervertebral joints and will thus allow for cyst resorption and clinical symptom resolution. 4. Percutaneous implantation of an "In-Space" interspinous spacer is a minimally invasive method of dynamic stabilisation that means no restrictions in patients' activities and reduces the length of hospital stay.

[Spinal cord concussion: a retrospective study of twenty-four patients].
Spinal cord concussion is characterised as fully reversible, temporary inhibition of conductive function due to trauma, without signs of structural changes. Although neurological deficit is usually related to the severity of spinal injury, this is different in spinal cord concussion. The aim of this retrospective study was to evaluate a group of 24 patients with spinal cord concussion, to design a diagnostic algorithm and propose an effective therapy with a good prognosis for the patients. ⋯ Spinal cord concussion is not a frequent injury; in our study, it accounted for 3.54% of the patients with trauma histories out of the total number of 678 patients, or for 2.40% out of 997 injured spinal levels. The first steps should be the same as in any other injury to the spinal cord. An early examination of the patient with imaging methods including MRI is of primary importance. At present administration of methylprednisolone according to the NASCIS system is disputable. The patient diagnosed with spinal cord concussion has a good prognosis, with rehabilitation as the main therapeutic approach.
