Abstract PDF: PURPOSE
This study was performed to evaluate the results of treatment of the humerus shaft fracture with interlocking IM nail.
MATERIALS AND METHODS
The result of IM nailing for 29 patients with humerus shaft fracture were evaluated radiologically and clinically. We tried to compare the result of Seidel nail and that of interlocking nail.
RESULTS
The results were as follows ; 1. Nonunion rate was 50% in Seidel nail group and 27% in interlocking nail group(p=0.264). 2. Operation time was shorter in Seidel nail group(67.8min) than in interlocking nail group(115.4min)(p=0.002). 3. Fracture site distraction was present in 9 cases and resulted in nonunion in 8 cases. 4. Union time except the nonunion cases was 10.4weeks in Seidel nail group and 11.9weeks in interlocking nail group but was not considered to be significant due to many nonunion cases. 5. Proximal protrusion was present in 6 cases but resulted in shoulder LOM and pain in only 2 ). cases.
CONCLUSION
Although the operation time in Seidel nail group was shorter than in interlocking nail group, we couldn't find any other difference between the two nails. The results of treatment of humeral shaft fracture with interlocking nail was unsatisfactory in terms of union rate, complications, union time and functional result.

Nonunions of the Humeral Shaft Fracture after treating by the Seidel Humeral Locking Nail: Young Bae Pyo, Kong Min Shin, Pyong Ju; J Korean Soc Fract 1998;11(3):690-695. Published online July 31, 1998; DOI: https://doi.org/10.12671/jksf.1998.11.3.690

Abstract PDF: The authors analyzed 34 cases of humeral shaft fractures in patients who were treated by the Seidel intramedullary nailing from March 1994 to August 1996. Average follow-up period was 18 months(12 months - 26 months). We experienced nonunions of 5 cases(14.7%). The nonunions were found mostly at the comminuted midshaft fractures. The probable cause of nonunion was distraction of fracture ends due to intramedullary endosteal lysis and failure of fanning within postoperative 3 months. These 4 cases of nonunion were treated with rigin internal fixation and additional bone graft, and 1 case with refanning only. So we concluded that the eidel system ws insufficient fixation technique because of the distal spreading-fin loosening. Distal screw-locked nailing seemed to be nn more useful technique unless there are major modifications to the Seidel nail itself.
