The Effect of Smoking on Posttraumatic Pseudoarthrosis Healing after Internal Stabilization, Treated with Platelet Rich Plasma (PRP).

Unlabelled: Disturbed or delayed healing remains one of the most serious fracture-related complications, despite bone capacity for internal regeneration and reabsorption. Considerable progress in the understanding and treatment of fractures has been noted. The aim of our study was to evaluate treatment outcome in patients (smokers and non-smokers) with post-traumatic pseudoarthrosis.

Surgical treatment of advanced, stiff neurologic cavovarus foot in adults.

Background: Cavovarus foot is a complex, three-dimensional deformity of neuromuscular origin. A rigid cavovarus deformity causes difficulty in walking, instability, fatigue fractures, calluses and trophic ulcers in the overloaded lateral part of the foot and requires wearing orthopaedic shoes. The aim of the study was to evaluate current surgical techniques in the treatment of rigid cavovarus foot in adults.

The concentration of manganese, iron, and strontium in hip joint bone obtained from patients undergoing hip replacement surgery.

The aim of this study was to determine the concentrations of manganese (Mn), iron (Fe) and strontium (Sr) in the cartilage with adjacent compact bone and spongy bone collected from patients after total hip replacement surgery. In addition, we examined relations between the concentrations of the metals in the bone and selected environmental factors. The concentration of Fe was the highest while Mn concentration was the lowest.

[The influence of hypersensitivity to nickel, chrome and cobalt on the process of fracture healing in patients treated operatively by stable osteosynthesis].

The aim of the study was to evaluate the frequency of occurrence of the hypersensitivity to nickel, chrome and cobalt in patients with longbone fractures. Two groups of patients were compared. The first group was composed of those treated operatively by stable osteosynthesis with the use of metal implants.

Surgical treatment of chondrosarcoma with massive bone destruction.

Background. The purpose of the study is to present the results of surgical treatment of chondrosarcoma in patients with massive bone destruction. Material and methods.

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.
