TST Telescopic Nail

TST Pediatric Telescopic Nail

The Telescopic Nail fron TST improves children’s quality of life. The state of the art telescopic structure does not have an impact on the epiphysis, provides anti-rotational stability and allows for children's bone development.


The Telescopic Nail indicates for children older than 18 months who are diagnosed with osteogenesis imperfecta. This nail’s other indications are children's long bone deformity corrections and fracture stabilization. It prevents the patient from fracture and also associates lengthening with external fixators. Additionally, The Telescopic Nail is for patients with osteoporotic bone.
The Telescopic Nail is made of medical stainless steel. It consists of 2 parts; D profile Bar (male nail) and suitable D profile tube (female nail) with threaded end. There is also angled female nail which is designed for tibia.
The male, the female and the angled female nails have five different diameter choices. The male nail has one length choice for each diameter, which could be adjusted to the desired length by cutting the nail. The female nails have 5 different length choices and the angled female nails have 3 different length choices for each diameter.
During the growth of the child’s bone, the nails grow without any hinderance due to the engagement of the male and female nails. There is a special designed corkscrew end on the distal part of the male nail that holds the bone solidly and gives minimal damage to the growth plate.
Female nail’s cancellous proximal threads fix the nail to the bone. Proximal locking screw which is sent to the bottom of the cancellous threads of the female nail, avoids the female nail to move forward.
The Angled Female Nail has a gap (opening) on which the male nail can go through. Two slots and a hole, on which Kirschner wire can be used for fixation, are on the angled proximal part. The threads on the proximal part allow the fixation of the end cap and prevent the nail to exceed out of the bone,
The application of the nail for tibia and humerus is from the proximal part and for femur from proximal and distal part of the bones.
