BACKGROUND: The optimal fixation of metacarpal @entity174 should provide sufficient stability to permit early functionfor all types of @entity174 . However; it must preserve surrounding soft tissue during application and not require secondary removal due to its prominence. The prototype of @entity5806 ( @entity5806 ) was designed by our institute aiming to achieve those allfeatures. OBJECTIVE: To biomechanically test our newly designed, locked metacarpal nail and compare with common current available fixation methods. MATERIAL AND METHOD: Thirty @entity1573 humeri were devided into 3 groups (n = 1 per group) according tofixation techniques: @entity5806 , 1.5 mm miniplate (Synthes), and Kirschner wire. After complete fixation, all specimens were osteotomized at mid-shaft creating transverse @entity174 . Five specimens from each group were tested by load of failure under axial compression, and another five under bending force. RESULTS: In axial compression model, the loads tofailure in @entity5806 group was greatest (460    17 N), which was significant higher than the Kirschner wire group. The @entity5806 group also showed the highest load to failure in bending test (341    10 N). This value reaches statistical significance when compared with plate and Kirschner wire groups. CONCLUSION: The @entity5806 construct provided higher stability than miniplate and Kirschner wire fixation both in axial and bending mode. Together with the minimally invasive and soft tissue-friendly design concept, this study suggests that @entity5806 is promising fixation option for metacarpal @entity174 .
