Tibial retrograde intramedullary nails manufactured by ChM company are designed for stable osteosynthesis of the tarsus and the distal tibia, for the treatment of degenerations and deformities of the tarsal joints.
Indications for retrograde nailing:
• tibiocalcaneal arthrodesis;
• combined arthrodesis of talocrural joint and talocalcaneal joint;
• avascular necrosis of talocalcaneal joint and talocrural joint;
• rheumatoid arthritis;
• severe, secondary deformity of untreated congénital club foot (talipes equinovarus) or in the case of the neuromuscular disease;
• seriously deformed foot / tarsal joint, arthritic deformity of tarsal joint with associated stiffness in the talocalcaneal joint;
• osteoarthritis;
• instability and skeletal defects after tumor resection;
• distal tibial fracture non-unions;
• tibial plafond fracture and / or talus where reconstruction is not possible;
• severe multifragmentary fractures with associated damage to the talocalcaneal joint;
• fractures, dislocations of the tarsal joint combined with serious arthritic changes and loss of function;
• above-ankle non-union combined with stiffness in the talocalcaneal joint;
• mal-union of tarsal joint;
• after a failed total tarsal joint replacement with talocalcaneal joint intrusion.
The nail has 6 holes for locking screws in its proximal and distal part. Locking is performed using the targeters included in the instrument set and additional targeters.
