Current modalities for osteoarthritis (OA) treatment are partially safe and effective, and only alleviate the disease symptomatology, but do not modify progression and structural changes of the ...disease. At present, there is no approved safe and effective disease-modifying OA drug (DMOAD) for clinical application. Therefore, there is an urgent need for discovery of DMOAD in order to treat OA. Hopefully, the new DMOADs would also pave the way for better understanding of OA pathophysiology. Given the fact that there is still no adequate remedy that will modify the course of OA, a number of emerging pathways and promising agents with possible DMOAD effect arise targeting cartilage, synovial membrane, and subchondral bone, or using stem cell therapy, and gene therapy. All these methodologies will be described and discussed in this review. Available treatment methodologies for OA are unsatisfactory. In order to properly treat OA in the future, more realistic option will be the use of multiple drugs, instead of single therapy, which is likely to be ineffective in the treatment of such heterogeneous diseases. Which combination of drugs with DMOAD effect will be suitable for the treatment of OA, remains to be determined in future studies.
The muscle sparing total hip arthroplasty had generated a distinguishable interest, in both the patients and the surgeons, but its benefits are still often questioned. The main idea of this study was ...to compare the functional clinical outcome of the patients operated by the anterolateral approach with a muscle-sparing technique (modified Watson-Jones approach), and the patients operated by modified direct lateral approach without the muscle-sparing technique (Bauer/Hardinge approach).
The patients (N = 130) were divided into two groups: 68 in a standard method group (STAND) and 62 patients in a muscle sparing surgery group (MSS). The hip flexibility, mobility, the strength of the hip abduction, the pain scale, Harris hip scores, the duration of the hospital stay and the overall satisfaction were measured seven days, three months, one year and three years (in 80 patients) after the surgery. There were no differences in any of the parameters between the groups prior to the procedure.
The statistically significant differences in first three follow-ups (up to one year) were determined between the groups in passive and active hip flexion ability but the hip abduction strength, which is a crucial parameter for functional recovery, and 50 m walk test remained better in MSS group even after three years. Patients, who underwent MSS suffered also less pain, stayed in hospital shorter and were more satisfied with the operation outcome.
The functional recovery in patients treated with muscle sparing method was faster than in patients operated with conventional lateral approach. Based on the results, we could recommend anterolateral muscle sparing approach for a total hip replacement for its faster and fuller functional recovery.
Osteoarthritis (OA), the most common chronic musculoskeletal disease, represents a leading cause of disability in the elderly population worldwide. At present, there is no aetiological treatment for ...OA patients. Also, current therapeutic regimens for OA are only partially effective, and that is the main reason for most physicians’ complaints. Therefore, one of the biggest challenges in the future will be to find the most appropriate therapy or therapies for OA. Currently, there are three basic modalities of treatment: nonpharmacological, pharmacological and surgical. Regarding pharmacological treatment, numerous molecular pathways involved in the pathophysiology of OA have been investigated as potential therapeutic targets. In preclinical and clinical trials, many compounds and agents have been tested, and some of them have already shown positive effects on the progression of knee and/or hip OA. One such possible pharmacological treatment of OA is anticytokine therapy. Interleukin-1 (IL-1), as a main inflammatory and catabolic cytokine in the pathophysiology of OA, represents one of the possible treatment targets. For specific inhibition of IL-1 production or activity, various treatment strategies could be used. These include the inhibition or modification of IL-1 action through the application of IL-1 receptor antagonist proteins, soluble IL-1 receptors, monoclonal antibodies against IL-1 or against IL-1 receptor I, blocking the formation of active IL-1β, blocking the IL-1 cellular signalling pathways, or using gene therapy. All the abovementioned treatment strategies for specific inhibition of IL-1 production or activity have been investigated in numerous preclinical and clinical studies. Some of these investigations led to the discovery of new potential drugs for the treatment of OA. However, the results of treatment with these drugs were not entirely satisfactory, and further research is required to achieve the desired goals of therapy.

The aim of our study was to investigate the changes in drug usage and financial expenditure according to legal changes in Croatia during the period 2001 - 2008, especially considering pricing policy.
...The data on outpatient drug usage during the studied period was obtained from the Croatian National Health Insurance (CNHI). CNHI maintains a database on drugs prescribed by primary health care physicians and dispensed by pharmacies.
The data was calculated and presented in defined daily doses (DDD) per inhabitant per year for antibiotics and in DDD/1,000 inhabitants/day for other drugs. The data is also presented in Euro/DDD and the financial expenditures are presented in Euros.
During the investigated period drug usage increased 81.33%, while financial expenditure increased 77.23%. While total DDD/1,000 increased ~ 10% every year, financial expenditure increased 10 - 20% annually until 2006, but since then there have been no significant changes.
Pricing policy changes could influence drug financial expenditure considerably in the short-term, but it is also important to apply a combination of measures for drug expenditure control. Numerous interventions from authorities from different countries all over the world, prove that there is still no so called "gold standard" which could restrain growing usage and expenditure of drugs. Clinical pharmacologists and clinical pharmacists should be included in these processes.
Treatment of infected tibial nonunion with bone defect represents a challenge for every orthopaedic surgeon. Various methods of treatment have been described for nonunions with infection, bone loss ...or both. One of them is the central bone grafting technique, which is a safe and effective treatment for nonunions of the tibia. The technique involves placement of autogenous cancellous bone from the iliac crest on the anterior surface of the interosseous membrane with the aim of creating a tibiofibular synostosis. We present the results of uncontrolled, retrospective and continuous series of ten patients treated by a central bone grafting technique for infected tibial nonunion with bone loss. Mean follow-up period was 12 (10-15) years. Most injuries were a result of war injuries. Clinically and radiologically confirmed bony healing with total consolidation of the graft was achieved in all patients within a period of 10-12 months without further bone grafting. The newly-formed bone mass was able to fulfil the mechanical and functional demands of everyday life activities. Once again, the central bone grafting technique has shown to be a safe, reliable and effective method of treatment for infected tibial nonunion with bone defect.
Aim:
The aim of our study was to assess diagnostic value of magnetic resonance cholangiography (MRC) in patients with suspected common bile duct (CBD) stones focusing on the capability of this ...noninvasive method to replace invasive diagnostic procedures in these patients and to limit the use of endoscopic retrograde cholangiography (ERC) to the patients who need simultaneous therapeutic intervention.
Materials and methods:
Single‐shot fast‐spin‐echo rapid‐acquisition thick‐section MRC images were obtained in 310 patients recruited into this prospective study. There were 136 male and 174 female patients aged 21–95 years mean ± standard deviation (SD) 64.9 ± 13.6 years. Patients were subsequently classified into different risk groups (high, moderate, low) according to biochemical abnormalities or morphological features on abdominal ultrasonography and computed tomography. Direct cholangiography was the reference method of CBD evaluation.
Results:
CBD stones were diagnosed in 115 (37%) patients; 86 of 175 patients in the high‐risk group, 24 of 83 patients in the moderate‐risk group, and 5 of 50 patients in the low‐risk group. In dependent risk groups, the mean CBD caliber was 9.7 ± 4.5, 7.1 ± 2.0, and 4.8 ± 1.2 mm, respectively. The difference was significant between all three groups (P < 0.05). The median size of CBD stones was 7 mm (range 3–21 mm). MRC achieved accuracy and positive and negative predictive values of 97%, 94%, and 98%, respectively.
Conclusions:
MRC has a potential to substitute diagnostic ERC in all patients with suspected choledocholithiasis due to its high accuracy, reducing invasive direct cholangiography to patients who require therapeutic intervention.

Abstract The “cello technique” is a new calcaneoplasty technique for the treatment of Haglund disease. It is an ultrasound-assisted technique for resection of the posterosuperior part of the ...calcaneus. It is possible to resect the posterosuperior part of the calcaneus under direct ultrasound control with the patient in the prone position, with a dorsally positioned ultrasound probe, in line with the Achilles tendon fibers (sagittal line), and with the abrader in the posteromedial working portal. We describe in detail the technique for this new procedure in foot and ankle surgery. This innovative technique offers the possibility of expanding the indications for ultrasound-guided surgery in other fields of orthopaedic surgery.

Acute coronary syndrome (ACS) presents today the leading group of post-operative cardiovascular complications, while endothelial dysfunction (ED) is one of the key elements in its development. The ...chronic ED represents thus the basis for the gradual development of atherosclerotic changes, while its sudden aggravation leads to ACS. The persistent ED occurs due to the effects of chronic cardiovascular risk factors, while according to the available studies it can also develop or aggravate under the impact of different acute events. We have directed this study to the investigation of the dynamic of endothelial function before and after a major orthopaedic surgical intervention. This randomised prospective study included 19 patients that underwent the intervention of total knee replacement and 20 healthy examinees of the adequate age and gender High-resolution ultrasound test based on the flow mediated dilatation of the brachial artery is what at we carried out at the beginning of the research, respectively 12, 24, 48 and 72 hours, as well as 7 days after the surgical intervention. The starting values of the FMD test were within the normal range in both groups, although the ability of dilatation upon stimulus was significantly lower in the investigated group. The FMD percentage change in the total sample was negatively connected with the body weight, not having shown additional connections with other cardiovascular risk factors. During the early post-operative period, a significant transitory lowering of the FMD percentage change was recorded, having reached the lowest value 24 hours after the surgery. During the seven-day prospective surveillance, no significant cardiovascular complications were recorded. Further research is necessary in order to confirm these results as well as the testing of the possible connection of the described post-operative transitory endothelial dysfunction with the development of cardiovascular complications and the adverse event.
Congenital dislocation of the knee (CDK) is a very rare condition. Here we report our strategy and results in treatment of three children with CDK. All three patients were treated with conservative ...method, and only one had underwent a surgical procedure on one knee. Of the remaining, we recorded a good outcome with conservative treatment in three knees, while two had poorer outcome as a result of musculoskeletal anomalies. We also present here a unique case of a child born without cruciate ligaments and patellas on both sides. We performed the operative procedure by Z-plasty of the extensor apparatus on one left knee according to Niebauer and King on one child. The clinical result of this procedure was very good. Five years after the operation we decided to perform an MRI examination to assess the postoperative status of the operated knee, especially the position and the shape of left patella. We found the asymmetry and high position of the operated patella resulting in patella alta. Compared to the initial clinical presentation, we consider all patients to have good clinical presentation nowdays.
