[Allofit cementless acetabular component: five-year experience].
To evaluate the mid-term results of using the Allofit cementless acetabular cup for primary hip replacement. ⋯ Cementless press-fit cups have very good outcomes, even in a long-term follow-up. Our experience gives support to these results because of a low number of hips with loosening, both septic and aseptic, or polyethylene wear of the primary implanted acetabular cup, and no cup migration in our patients. The five-year survival rate of the Allofit acetabular cup was 95.8%.

[Evaluation of the clinical results in patients with symptomatic partial tears of the anterior cruciate ligament diagnosed arthroscopically].
The study presents a retrospective evaluation of clinical data and arthroscopic findings in a group of our patients with symptomatic knee instability due to a partial tear of the anterior cruciate ligament (ACL). ⋯ To make the definite diagnosis of partial ACL tears, patient medical history, clinical knee examination including instability type and degree assessment under general anaesthesia and, most importantly, arthroscopic findings on both ACL bundles are necessary.

[Multivariate analysis of blood loss during primary total hip or knee arthroplasty].
The primary aim of the study was to identify characteristics predicting the blood loss associated with primary total hip (THA) and knee (TKA) arthroplasty surgery. The other objective was to find out which characteristics were important for peri-operative allogeneic blood transfusion in the same group of patients. ⋯ The patients with low pre-operative Hb levels have a high probability that they will require allogeneic blood transfusion during primary THA and TKA. Autologous blood donation can decrease this probability significantly (here proved only for THA patients). The multivariate model of blood loss published here could assist in estimation of peri-operative blood loss and potential risk of blood transfusion requirements.

Comparative Study[Pelvic injuries and acetabular fractures: differences in their severity].
The aim of the study was to assess differences in the number and severity of associated injuries between patients with pelvic injury and those with acetabular fracture. ⋯ The study comparing the patients with pelvic injury with those having acetabular fracture showed a significantly higher proportion of men in the group with acetabular fractures. A fall from height significantly more often caused a pelvic injury than an acetabular fracture. In traffic accidents, drivers usually suffered acetabular fractures while pedestrians and cyclists had pelvic injuries. However, a significantly higher number of associated injuries and multiple trauma with an ISS > 16 recorded in the patients with pelvic injury in comparison with those with acetabular fractures was the most important difference between these two groups.

[Hinged external fixation in orthopaedic and trauma surgery of the elbow].
A hinged external fixator of the elbow provides stable fixation of the joint while maintaining the range of its motion. The aim of the study was to evaluate a group of patients in whom an external fixator was used to manage severe injuries to the elbow, namely, traumatic unstable dislocation, unstable fracture-dislocation, and elbow fractures not permitting management by primary osteosynthesis. This also involved assessment of early elbow mobilisation and a comparison of this group with a group of patients treated conservatively for less severe elbow injuries. ⋯ Elbow injuries differ from patient to patient and therefore the approach to their treatment has to be individual in every patient. A hinged external fixator provides stable fixation and allows for early movement of the elbow. Maintenance of the range of motion facilitated by the hinged fixator is not at the expense of joint stability or fracture non-union. Based on the results presented here, we recommend the use of external fixation in severe unstable elbow fractures and in fractures in which primary osteosynthesis cannot be used because of soft tissue injury.
