The Sorin Pericarbon Freedom Stentless aortic valve has the potential to provide superior hemodynamic function and durability. In this study we assessed the hemodynamic performance of this valve and its impact on LV-mass regression after aortic valve replacement. ⋯ The hemodynamic performance of the Sorin Pericarbon Freedom Stentless aortic valve is excellent and the patient outcome is satisfying. However the implantation technique requires longer ischemic time, the prosthesis offers very satisfying hemodynamic function and accelerates probably the LV-mass regression in the mid term follow-up. Late performance and durability of the valve have to be assessed.

We present a case of spontaneous rupture of the spleen, an uncommon complication of systemic amyloidosis. Amyloid deposition leading to capsular distension and increased vascular fragility is thought to predispose the spleen to rupture spontaneously.

While soccer playing a 19 year old man suffered from acute onset of severe pain in the anterior part of the iliac crest. A CT-scan confirmed the unilateral avulsion of the anterior superior iliac spine. Due to only minimal fragment dislocation and still open apophysis we decided to treat this injury conservatively with crutches and partial weight bearing. ⋯ The avulsion occurs by sudden pull of the sartorius muscle to the anterior superior iliac spine. The pull of the muscle dislocates the loose fragment caudally. In most of the cases a conservative treatment is successful.

Case Reports
[Osteosynthesis of combined radius head and capitulum humeri fractures with mini-implants].
Combined injuries of the capitellum humeri and the radial head are rare. Most of them show combined osteocartilaginous lesions and collateral ligament lesions. Recommendations for treatment of these fatal injuries of the elbow are missing. ⋯ Direct screw fixation with mini-implants, eventually combined with resorbable pins allows to use the same approach for anatomic reconstruction and fixation of the capitellum humeri and radial head. Transarticular fragment fixation of the capitellum allows for safe compression. Therefore early functional rehabilitation is possible postoperatively. Secondary interventions for improve joint motion were necessary in three of five cases.

The intramedullary Kirschner wire fixation of distal metacarpal fractures reported by Foucher et al. combines the known advantages of intramedullary implants with a reduction of iatrogenic soft tissue trauma. We applied this minimal invasive internal fixation technique in 38 patients with fractures dislocated by more than 20 degrees and/or with rotatory deformity. After opening the intramedullary cavity from the base of the respective metacarpal bone and after fracture reduction, two pre-bent Kirschner wires were intramedullary inserted in an orthograde fashion. ⋯ With one exception, all fractures were healed in a proper position. The wires were removed under local anaesthesia on an outpatient basis after six to eight weeks and full mobility of the fingers was achieved in 34 patients at that time. Complications included one redislocation and one distal wire perforation.
