Comparative Study[Intramedullary fixation of humerus shaft fractures. An analysis of complications of 2 implants with special reference to outcome after management with the unreamed humerus interlocking nail].
Operative treatment of humeral shaft fractures has gained a new impetus with the development of intramedullary interlocking systems for the humerus. Because of the anatomical structure of the humeral marrow cavity, a regular jamming of nail into bone is not to be expected, so that the stability of these systems needs to be achieved through an interlocking mechanism. Among the commercially available interlocking nailing systems the unreamed humeral nail (UHN) and the Seidel-nail (SHN) can be regarded as the standard implants. ⋯ The possibilities of operative methods in treatment of humeral shaft fractures are enhanced by intramedullary interlocking systems. Comparing with the Seidel nail, the unreamed humeral nail (UHN) has two advantages: it can be inserted anterogradely as well as retrogradely, and it provides the possibility of compressing the fracture, resulting in a high rotational stability. Due to these results, the application of the UHN is recommended.
