The aim of this study was to find the correct angle of the needle position for the epidural perineural injection at the lumbar spine without any help by imaging. ⋯ With some training it is possible to perform epidural-perineural injection for sciatica without the help of imaging.

Comparative Study
[Results after replacement of femoral neck prostheses - thrust plate prosthesis (TPP) versus ESKA cut prosthesis].
The aim of this study was to analyse and evaluate comparatively loosening mechanisms, failure frequency, surgical changing strategies and results after replacement of thrust plate prostheses (TPP) and ESKA Cut prostheses. ⋯ In comparison with the usually problem-free changing procedure of the TPP to a standard type stem, the revision surgery of the Cut prosthesis becomes substantially more complex and leads frequently to complications. In view of unacceptable survival rates, the Cut prosthesis does not represent an alternative implant in young patients. Except for the implantation technique, which does not allow a less invasive surgical procedure, the TPP fulfils the requirements of femoral neck prosthesis due to acceptable survival rates and good convertibility.

Correction of severe tibial deformity due to a non-union of the tibia is best achieved by a slow gradual correction which allows the compromised tissue to adapt. The Taylor spatial frame (TSF) is a hexapod-based ring fixator that allows a simultaneous gradual correction of a multiplanar deformity through a virtual hinge. The aim of this study was to demonstrate the application of the TSF and the clinical outcomes of ten patients with a non-union of the tibia. ⋯ In patients with either a hypertrophic or oligotrophic non-union of the tibia and severe deformity, the TSF is a powerful tool to correct the deformity in a closed manner which preserves the remaining viability of the non-union.

This cohort study shows the results after treatment of comminuted radial head fractures combined with elbow instability, using radial head arthroplasty. ⋯ An arthroplasty with a radial head prosthesis can be recommended for unreconstructible comminuted radial head fractures with ligament injury.
