In this paper, a case of closed medial subtalar dislocation and accompanying talar head fracture in a 22-year-old man which occurred while walking on a downhill road is reported. Closed reduction under general anesthesia was unsuccessful. The obstacle for closed reduction was determined at surgery for open reduction and internal fixation as buttonholing of the talar head through the extensor retinaculum. At the 26-month follow-up, he was pain-free in his daily activities.

The thrust plate prosthesis in patients with aseptic osteonecrosis of the femoral head.
The thrust plate prosthesis (TPP) is an implant with a metaphyseal fixation at the proximal femur that transmits the load forces of the hip onto the femoral neck. The osseous incorporation of the TPP and the adaptation of the bone to this force transmission depend on the bone quality, which is reduced to minor vitality and stability in patients with osteonecrosis of the femoral head. Depending on the etiology of the femoral head necrosis, the TPP might lead to early failures. ⋯ Femoral head necrosis following renal transplantation and extension of the necrotic area into the femoral neck are contraindications for TPP. Excluding these patients, the TPP shows comparable mid-term results to cementless stemmed prostheses and supplies advantages especially for younger patients, because of its metaphyseal, bone-preserving fixation. However, evaluation of the clinical impact of the TPP in comparison with other cementless femoral stem systems requires long-term examinations in the future.

Percutaneous, arthroscopically-assisted osteosynthesis of calcaneus fractures.
The development of major and minor wound complications is a major concern in the open reduction and internal fixation of displaced intra-articular calcaneus fractures. Percutaneous, arthroscopically assisted screw osteosynthesis was developed to minimize the surgical approach without risking inadequate reduction of the subtalar joint. The method was applied in selected cases of displaced intra-articular calcaneus fractures with one fracture line crossing the posterior calcaneal facet (Sanders type II fractures). ⋯ Percutaneous, arthroscopically assisted osteosynthesis offers exact assessment of the articular surface and allows anatomical reduction while adhering to the principles of minimally invasive surgery. The short-term results are excellent, while long-term results with greater patient cohorts are awaited.

Evaluation of functional outcome of the floating knee injury using multivariate analysis.
The objective of this study is to evaluate significant contributing factors affecting the functional prognosis of floating knee injuries using multivariate analysis. ⋯ The multivariate analysis showed that both the involvement of the knee joint and the severity grade of soft-tissue injury in the tibia represented significant risk factors of poor outcome in floating knee injuries in this study.

Case ReportsDistraction of hypertrophic nonunion of tibia with deformity using Ilizarov/Taylor Spatial Frame. Report of two cases.
Two cases of hypertrophic nonunion of the tibia with deformity for which distraction treatment using an Ilizarov/Taylor Spatial Frame (Smith & Nephew, Memphis, TN) are presented. This frame utilizes a computer program to help plan correction of the deformity.
