The association between specific olecranon fracture characteristics (e.g., displacement, fragmentation, subluxation) and fracture line distribution might help surgeons predict intra-articular fracture location based on fracture characteristics that can be determined on radiographs. We hypothesized that fracture mapping techniques would reveal different fracture patterns for minimally displaced fractures, displaced fractures, and fracture-dislocations of the olecranon. ⋯ III.

Arthroscopic treatment of symptomatic discoid meniscus in children.
To study discoid meniscus in children who underwent arthroscopic surgery at our center. ⋯ Although the short-term outcome after saucerization with or without suture repair for discoid meniscus is favorable, degenerative change or change of lower limb alignment may occur in the long term. Further long-term study is required.

Treatment of digital pyogenic flexor tenosynovitis: single open debridement, irrigation, and primary wound closure followed by antibiotic therapy.
Digital pyogenic flexor tenosynovitis requires fast, aggressive treatment. Although this infection occurs frequently, treatment consensus is lacking. ⋯ A single open debridement with irrigation and primary wound closure followed by 10 days of antibiotic treatment resolved uncomplicated pyogenic flexor tenosynovitis. After 2 and a half years, the treatment yielded high patient satisfaction with neither functional nor subjective impairment of the affected finger.

Does a positioning rod or a patient-specific guide result in more natural femoral flexion in the concept of kinematically aligned total knee arthroplasty?
Flexion of the femoral component in 5° increments downsizes the femoral component, decreases the proximal reach and surface area of the trochlea, delays the engagement of the patella during flexion, and is associated with a higher risk of patellar-femoral instability after kinematically aligned TKA. The present study evaluated flexion of the femoral component after use of two kinematic alignment instrumentation systems. We determined whether a distal cutting block attached to a positioning rod inserted perpendicular to the distal femoral joint line in the axial plane and 8-10 cm into the distal femur anterior and posterior to the distal cortex of the femur in the sagittal plane or a femoral patient-specific cutting guide sets the femoral component in more natural flexion. ⋯ Because a distal cutting block attached to a positioning rod sets the femoral component in 5° less flexion and with less variability than a femoral patient-specific cutting guide, we prefer this instrumentation system when performing kinematically aligned TKA to reduce the risk of patellar-femoral instability. Each surgeon should determine the repeatability of setting the flexion of the femoral component with this instrumentation system.
