Early migration characteristics of a 180° porous-coated cup with 1-mm press fit.
Evaluation of early cup movement is an important diagnostic tool to predict the likelihood of long-term implant loosening and clinical failure. The investigated cementless cup is clinically proven over 10 years, but there is a paucity of information that accurately describes the migration characteristics of this component. ⋯ Surgeons may expect to find a variable amount of early migration when using the Pinnacle cup. To our knowledge, these are the first results, which show an early "impaction" of a cementless cup, followed by subsequent osseointegration. We believe that an appropriate long-term outcome of the investigated cup is ensured. The data of the present investigation will provide clinicians with useful baseline information with which to compare new cup designs.

Comparative StudyMultiple drilling compared with standard core decompression for avascular necrosis of the femoral head in sickle cell disease patients.
Sickle cell disease (SCD) is the most common cause of avascular necrosis of femoral head (ANFH) in childhood. Advances in medical treatment led to improved life expectancy of such patients. SCD-related ANFH frequently progress to total collapse of the femoral head necessitating hip replacement. However, SCD patient are at more risk of intra- and post-operative complications and suboptimal outcome of total hip arthroplasty. Hence, it is imperative to preserve the femoral head as long as possible. ⋯ While multiple drilling is safer and less invasive than single coring in SCD, there is no statistically significant difference in outcome or complication rate between both procedures done for ANFH in patients with SCD.

The effect of rotational deformity on patellofemoral parameters following the treatment of femoral shaft fracture.
The purpose of this study was to investigate the effect of rotational deformities on patellofemoral alignment using the dynamic magnetic resonance imaging method on patients whose femur fractures were treated with intramedullary locking nails. ⋯ The results of this study revealed that more than 10° of external rotation deformity could cause a detoriation in the patellofemoral scores. Anatomic reduction of the fracture site should be performed as soon as possible and external rotational deformities should especially be avoided in order to prevent patellofemoral malalignment.

Minimally invasive plate osteosynthesis for humeral shaft fracture: a reproducible technique with the assistance of an external fixator.
Minimally invasive plate osteosynthesis (MIPO) has become a popular option for treatment of humeral shaft fractures. However, indirect reduction might risk unpromising results, with mal-alignment/mal-union or nonunion. The purpose of this study was to describe a reproducible MIPO technique that used an external fixator during the procedure as a tool for reduction and maintenance, and to assess the outcomes in patients with humeral shaft fracture. ⋯ Surgical treatment of humeral shaft fractures with external fixator-assisted reduction and MIPO resulted in excellent reductions and high union rates.

Comparative StudyRadio-lunate arthrodesis in rheumatoid arthritis: outcome and techniques.
The wrist is one of the most affected joints in rheumatoid arthritis. The purpose of this retrospective study was to assess clinical, functional and radiographic results of radio-lunate arthrodesis. Two different operation and fixation techniques are compared and detailed outcome after this intervention is presented. ⋯ Due to high patient satisfaction and functional outcome, radio-lunate wrist arthrodesis can be recommended independent of fixation method.
