Impact of Varied Factors on Iron, Nickel, Molybdenum and Vanadium Concentrations in the Knee Joint.

The aim of this study was to determine the concentrations of iron, nickel, molybdenum, and vanadium in the knee joint. We also examined the relationships between the concentrations of these metals in the knee joint and the influence of varied factors on the concentration of Fe, Ni, Mo, and V. The study of these trace elements is important, because these elements are used alone and in combination in diet supplements, and they are components of biomaterials implanted in medicine.

Concentration of Selected Elements in the Infrapatellar Fat Pad of Patients with a History of Total Knee Arthroplasty.

In the period of long development, the human body adapted to specific concentrations of trace elements. Any changes in the trace element content manifesting in a deficiency or excess of metals in the human body may impair the functioning of the skeletal and articular system and of the organs, and may also predispose the body to the development of diseases, i.e.

Phosphorus Concentration in Knee Joint Structures of Patients Following Replacement Surgery.

The aim of the study was to assess phosphorus (P) concentration in structures of the knee joint-including the tibial spongy bone, articular cartilage, meniscus, anterior cruciate ligament, and infrapatellar fat pad (Hoffa's fat pad)-of patients following knee joint replacement. The study also aimed to assess the influence of selected biological and environmental factors on P concentration in studied parts of the knee joint. Phosphorus concentration was determined using inductively coupled plasma-atomic emission spectrometry (ICP-AES).

Calcium, magnesium, zinc and lead concentrations in the structures forming knee joint in patients with osteoarthritis‬.

The aim of the study was to investigate the relationships between the concentrations of calcium (Ca), magnesium (Mg), zinc (Zn), and lead (Pb) in cartilage, anterior cruciate ligament, and meniscus samples obtained following knee joint surgery in patients with osteoarthritis in northwestern Poland.‬ Furthermore, we examined the relationships between the concentrations of these metals in the studied parts of the knee joint and the influences of gender, age, BMI and hypertension. We found significantly higher concentrations of Ca, Mg, and Zn in the cartilage of men than in women and a significantly higher Pb concentration in the meniscus of the men.

Solitary breast cancer metastasis to pelvic bone treated with a unique method of surgery combined with local doxorubicin administration.

Treatment of bone metastasis is a major challenge for current and future orthopedic and oncology specialists. For the treatment of single metastases, there is a continuing search for effective local treatments that do not affect the whole patient. The current report describes the case of single breast cancer metastasis to the pelvic bone in a 50-year-old woman treated surgically by bone osteotomy combined with local doxorubicin application.

The Effect of Risk Factors on the Levels of Chemical Elements in the Tibial Plateau of Patients with Osteoarthritis following Knee Surgery.

The aim of this study was to evaluate the aforementioned chemical elements in tibial plateau samples obtained during knee arthroplasty. The gender-specific analysis of chemical element levels in the bone samples revealed that there were statistically significant differences in the concentration of Pb and Se/Pb ratio. The contents of elements in the tibial plateau in the patients with osteoarthritis (OA) can be arranged in the following descending order: F(-) > K > Zn > Fe > Sr > Pb > Mn > Se > Cd > THg.

Percutaneous, Minimally Invasive Repair of Traumatic and Simultaneous Rupture of Both Achilles Tendons: A Case Report.

Achilles injury is a common musculoskeletal disorder. Bilateral rupture of the Achilles tendon, however, is much less common and usually occurs spontaneously. Complete, traumatic, and bilateral ruptures are rare and typically require long periods of immobilization before the patient can return to full weightbearing.

[The new bone formation and bone metabolism in Forestier disease].

The study was performed on 36 male patients between 65 and 83 years who were either hospitalised or treated in the out-patients clinic due to Forestier's disease. The aim of the study was to evaluate the advance of ectopic bone formation process in cervical spine and bony metabolic changes in treated patients. The study showed reverse corelation between the degree of advance of cervical hyperostosis and the prevalence of osteoporosis and metabolic disorders in the tested group.

Limitations of bone harvesting from organ donors in Poland.

The demand for organ transplantations greatly exceeds the number of organ donors (OD) and it is likely that this discrepancy will continue. There is a continuously growing demand for biostatic allogenic bone transplantation mostly for orthopedic reconstructions. The bone material is predominantly harvested during postmortem examinations in forensic medicine departments.
