BACKGROUND: Though mid-term survival rates of over 95% in several series have been published, there is still a paucity of related literature regarding the role of vertical stem instability in the osteointegration of fluted tapered stems. This paper presents a comprehensive and prospective assessment on short-term experiences with uncemented modular femoral stem in the treatment of defective femur during revision surgery of total hip replacement. MATERIALS AND METHODS: Clinical and radiological monitoring of 20 consecutive patients with implanted tapered fluted revision stem (Lima Corporate, Udine, Italy) was of 27 months in average (20-35 months). The average pre-operative Merle d'Aubigné and Postel method score was 6.3 points (3-10 points). The frequency of femur defects, classified according to Paprosky, was IIIA = 9 and IIIB = 11. RESULTS: During last follow-up, the Merle d'Aubigné and Postel hip score was on average 11.7 (6-16 points). Compared to post-operation radiograph, stem migration of 1.9 mm (0-11 mm) on average was found. This vertical stem migration was observed only when comparing hip radiographs immediately after surgery, and at 6 weeks post-surgery. The Paprosky IIIA defects group, presented a subsided stem by an average of 1.5 mm. In the group of Paprosky IIIB defects, the stem subsidence was on average 2.3 mm. All 20 patients in the study showed excellent osteointegration of the uncemented revision modular stem. CONCLUSIONS: This study found and excellent osteointegration of the Lima uncemented tapered fluted revision modular stem in defective femur with a cortical bone segment present in the diaphyseal isthmus area. The initial vertical instability leading to stem migrating during the first six weeks following surgery did not, however, affect its osteointegration. and P. Šponer, T. Kučera, K. Urban, D. Zítko, D.

Přehledový článek pojednávající na téma možných komplikací páskových operací běžně užívaných v léčbě stresové inkontinence moči. První metodou byla retropubická tahuprostá páska TVT, která s sebou nese zejména riziko poranění močového měchýře. V literatuře byly dále popsány komplikace typu závažného krvácení, poranění orgánů v malé pánvi, jako je střevo, nebo velkých cév. Další generace tahuprostých pásek se vyhýbá retropubickému prostoru vedením pásky skrz foramen obturatum. Tato generace má popsané riziko vzniku bolesti v třísle/tříslech. Avšak tato bolest většinou spontánně ustupuje, případně rychle odeznívá po podání nesteroidních antiflogistik. Poslední generace tahuprostých pásek jsou „minipásky“. Zavádí se z jednoho drobného řezu a jejich délka je menší než u předešlých generací. Rizikovost „minipásek“ spočívá v nedostatečné fixaci a tedy riziku selhání. Přestože se páskové metody používají celosvětově v klinické praxi již přes patnáct let, doposud nebyla vyvinuta metoda, která by byla jak naprosto bezpečná, tak úspěšná a jednoduchá k zvládnutí operatérem., This review focuses on possible complications during tape procedures carried out due to stress urinary incontinence. The first method was retropubic tension-free vaginal tape TVT that held mainly risk of bladder perforation. Further complications previously described in literature were severe bleeding and injuries of organs in lesser pelvis like bowel or great vessels. The next generation eliminated retropubic space by insertion through the obturator foramen. However another complication had been witnessed in presence of groin pain. Fortunately, this is usually transient and quickly passing either spontaneously or after use of non-steroid anti-inflammatory drugs. The last generation of tension-free vaginal tapes are “minislings” that are inserted from a single incision and are shorter in comparison with the previous generations. The risk of use of this “minislings” is in insufficient fixation and therefore failure of the procedure. Despite using tape procedures worldwide for more than fifteen years on regular basis, there is no method, that would be completely safe, effective and easy to handle for the surgeon., Petr Hubka, Rachid El Haddad, Jaromír Mašata, Alois Martan, Kamil Švabík, and Literatura
The aim of this study is to evaluate the results of total hip arthroplasty in patients with Parkinson's disease during a period of five years, focusing on the assessment of the risks and benefits of surgery. During this period we performed total hip arthroplasty in 14 patients (15 hips) with Parkinson's disease. Patients were evaluated by subjective symptoms and objective findings, with a focus on the use of support while walking and walking distance, severity of Parkinson's disease before surgery and at the time of the last follow-up. During the postoperative period, the following parameters were assessed: length of ICU stay, mobilization, complications, the total duration of hospitalization and follow-up care after discharge. Of the 11 patients (12 hips) followed-up 1-5 years with an average of 3 years after operation 8 cases showed progression of neurological disability. 5 patients (6 hips) showed an increased dependence on the use of support when walking and reduced distance that the patient was able to walk. Subjectively, 10 hip joints were completely painless and 2 patients complained of only occasional mild pain in the operated hip. Complications that were encountered were urinary tract infection (5 patients), cognitive impairment (3 patients) and pressure ulcer (2 patients). We did not observe any infection or dislocation of the prosthesis. Three patients fell and fractured the femur and 3 patients in our cohort died during follow up. Implantation of total replacement is possible with judicious indication after careful evaluation of neurological finding in patients with minimal or mild functional impairment of the locomotor system. Prerequisite for a good result is precise surgical technique and optimal implant position with balanced tension of the muscles and other soft tissues around the hip. and PG. Mathew, P. Sponer, T.
