Objective To determine whether autologous bone graft supplementation with open reduction and internal fixation of intraarticular calcaneal fractures is beneficial by prospective random research.

Objective To explore interference Factors influencing the therapentil effectiveness of intra-articular calcaneal fractures.

MethodSix intact human cadaver lower extremities were used to produce calcaneal intra-articular fracture models, fracture patterns of the model were observed with radiographical technique, and anatomical study was proceeded to observe the fractures and their effects on soft tissues and compartments in foot.

At twelve weeks,the healing and remodeling of the intra-articular fracture with step-off defect are examined with use of gross,LM and TEM .

Objective To explore the injury mechanism and operative treatment of intra-articular fracture of calcaneus.

Absorbable screws fixation for intra-articular fractures;

Absorbable screws for intra-articular fractures;

Treatment of tibial or femoral diaphyseal and knee intraarticular fractures with intramedullary nail;

Objective: To summarize the clinical experience of the internal fixation on calcaneus intraarticular fractures.

Aim: To ussess the clinical value of the treatment with open reduction and internal fixation with special plate in intraarticular fractures of the calcaneum.
