[Meniscuses and ligaments injuries in tibial plateau fractures in comparative evaluation of clinical, intraoperative and MR examination].

The diagnosis of the meniscal and ligament injuries accompanying the tibial plateau fractures is difficult and unconvincing. Thus the capsular, ligament and meniscal injuries coexisting with this kind of fractures were questioned for many years. Introducing of MR afforded for the precise evaluation of the bone as well as the soft tissue injury. This article demonstrates the results of MR images of 112 patients with the acute proximal tibia fractures. The number and the degree of the meniscal and ligament injury were estimated and intraoperative verification of MR was made in 66 patients qualified for an operative procedure. The attempt to find the correlation between the type of the fracture and the meniscal and ligament injury was made according to Schatzker classification. MR images revealed that the bone injury was accompanied by the ligament or meniscal injury in 88%. Most commonly the partial tears (77% considering ligament injuries and 70% considering meniscal injuries) occurred. The most frequent extracapsular and intracapsular injury was MCL tear (70%) and LM tear (56%) respectively. No correlation between the type of the fracture and the soft tissue injury was found.

[Dislocation after total hip arthroplasty].

From 1997 to 2002 in the Department of Traumatology there had been performed 488 total hip replacements: 334 in men and 454 in women at the age between 20 and 84 (average 63.6). The procedures were performed by 12 surgeons and postero-lateral approach was used. Dislocation was found in 22 patients (4.51%): 14 women and 8 men. Majority of dislocation occurred during first 8 weeks after an operation and 68% of them happened during first 6 weeks. The surgical treatment was necessary in 10 cases (45% of all dislocation): 3 patients had only a surgical reposition and 7 patients had a revision arthroplasty. There was found that most cases of dislocation took place at the age above 81 years. Dislocation occurred 5 times more frequently in patients operated on for a femoral neck fractures then for coxarthrosis. The prosthesis TT1 most often dislocated possibly due to its shape (low Head Neck Ratio). Based on our own experience we find dislocation is a multifactorial complication and precise description of causes is usually very difficult.
