The developed software in the form of MS Excel calculators provides a particular patient with preoperative assessment of the risk for minor acute dynamic pain on the 1 postoperative day and CPS 5-7 months after surgery.

Total hip replacement is an important orthopedic surgery allowing to increase high-activity profile and longevity of the elderly patients suffered from arthritis and proximal hip fracture. For the good outcome of the surgery we have to use enhanced recovery strategy which in turn needs performing adequate postoperative analgesia. Using painkillers only (per os, i.v., i.m., s.c.) after THR is not enough to reach this aim (well pain relief at rest and during movement) due to low analgesic potency of the non-opioid drugs and adverse reactions related to opioids, so, the regional analgesia methods are widely spread. Considered before as a gold standard epidural analgesia method is not quite suitable for the aged patients as so as the sympathetic and motor blocks hinder an enhanced recovery after THR. In recent decades the interest in peripheral regional analgesia methods has been gradually increasing. Fascia iliaca and psoas compartment blocks, local wound infiltration analgesia are getting the modern regional THR postoperative analgesia armamentarium. Each of them has some benefits and pitfalls and only face-to-face comparisons within the scope of clinical trials will give us the basic for the constituting the local and national post-THR analgesia guidelines.
