[Intra-operative periprosthetic fractures during THA in the period 1995-2009].

Purpose Of The Study: The aim of this prospective study was to investigate whether female gender and revision surgery were significant risk factors for intra-operative periprosthetic fractures during total hip arthroplasty (THA).

Material And Methods: The group investigated comprised the patients who, in the period 1995-2009, sustained an intra-operative periprosthetic fracture during primary or revision THA. The patients were treated by a therapeutic procedure based on the Vancouver system.

[Diclofenac 75mg. and 30 mg. orfenadine (Neodolpasse) versus placebo and piroxicam in postoperative analgesia after arthroscopy].

Purpose Of The Study: Arthroscopy is often performed in an out-patient department or as one-day surgery. Opioids often used as postoperative analgesics may have unwanted side effects that may postpone the patient's discharge from hospital. This study was designed to evaluate a substitute for the most frequently used opioid pethidine.

[The proximal femoral nail (PFH)--another alternative for osteosynthesis of trochanteric fractures].

The aim of the study was to test a new intramedullary implant PFH-Medin on internal fixation of trochanteric fractures. The basic group comprised 35 patients (average age 79.2 years).

[Duration of surgery in osteosynthesis of fractures of the trochanter].

Purpose Of The Work: To analyze duration of surgery in individual types of internal fixation of fractures of the trochanteric massif and identify factors which have an impact on it.

Material: Analysis covered a group of 137 patients treated with Ender nailing (EN), 314 patients by means of Dynamic Hip Screw (DHS), 74 patients by means of Gamma nail, 37 patients by means of Proximal Femoral Nail (PFN) and 13 patients by means of 130 degrees angled blade plate. The groups of patients included basicervical femoral neck fractures (29 cases), peritrochanteric and subtrochanteric fractures.

[Unstable pertrochanteric fractures, biomechanic, classification and therapy.].

The authors deal with unstable pertrochanteric, intertrochanteric and subtrochanteric fractures extending as far as calcar femorale. The treatment of pertrochanteric issues is a serious issue as their total number in the Czech Republic exceeds 5.000 annually and with the exception of those which are contraindicated due to their health condition, all patients are indicated to surgery.
