Diclofenac epolamine plus heparin plaster versus diclofenac epolamine plaster in mild to moderate ankle sprain: a randomized, double-blind, parallel-group, placebo-controlled, multicentre, phase III trial.

Background: In general sports, ankle sprain is the most frequently reported ankle injury and can cause chronic lateral ankle pain and tenderness. Treatment with NSAIDs is preferred, and several topical NSAID formulations are now available, helping to avoid the systemic adverse events typically associated with oral preparations.

Objective: To compare the efficacy and tolerability of a newly developed fixed-dose diclofenac epolamine (diclofenac hydroxyethylpyrrolidine, DHEP)/heparin plaster (Flectoparin® Tissugel) with that of a DHEP (Flector EP Tissugel®) or placebo plaster in the treatment of mild to moderate ankle sprain in adults.

Total hip replacement using unipolar and bipolar prostheses in the treatment of femoral neck fractures.

Background. The trials to replace head and neck hip fractures using allogenic material were undertaken nearly 100 years ago. In 1974 Baterman described the construction of bipolar prosthesis defined as intermediate type between half prosthesis and total prosthesis.
