The RETRON-System

The number and complexity of humeral head fractures increase with advancing age. A definite increase in incidents due to demographic changes can be expected. As a result of growing demands on physical activities, the tendency in favour of operative treatment for humeral head fractures will be observed.

The RETRON nail is suited to this development, given that, alternative procedures of treatment due to long physical-therapeutic follow-up treatment with only gradual improvement of the mobility, the patient’s claim to untimely physical activity is partially unjust. An implant system for this indication should include the possibility of:

  • Prevention of the humeral head
  • Minor invasive Operative procedure
  • Protection of the subacromial region

The goal of treatment with the RETRON system is the stabilisation and conservation of the bone structure. Entry of the RETRON nail occurs laterally transdermal, underneath the onset of the Delta muscle. The joint is not opened.

The anchorage of the fragments is carried out with the cannulated screws, which are angle and slip stable though the implantation of the RETRON nail. This principle of intramedullary force conduction and cannulated screws creates good stabilisation of the fragments and reduces secondary dislocations.

This system is suitable for subcapital and pertubercullary humeral fractures.

The RETRON system offers young patients with good bone quality splendid support of the fracture. Protection of the subacromial region through lateral entry underneath the onset of the Delta muscle is an important prerequisite for good rehabilitation results especially with young patients.

For the treatment of older patients with increasing osteoporosis, the demand for anchoring the implant in the humeral head is escalated.

The subchondral region of the bone is used for a reliable fixation of the RETRON nail. The nail is guided in just to the cartilage and generates a good condition for a stable osteosynthesis due to its proximal thread.

An additional advantage of the RETRON system is the complete preservation with all types of retraction.

All in all, the RETRON system complies with the accustomed tantum principle: The system is an innovative product, of the best quality, to economic conditions.
