Aim: To compare humeral interlocking nail andcompression plating in fracture of shaft of humerus cases. Methodology: One hundred ten cases of fracture of shaft of humerus of both genders were divided patients into 2 groups of 55 each. In group I, internal fixation by humeral interlocking nails was performed and in group II, internal fixation by dynamic compression plating, with or without bone grafting was performed. Parameters such as AO classification, mode of injury, level of injury, side, range of elbow joint movements, DASH score and complications in both groups were recorded. Results: Age group 20-30 years had 12 patients in group I and 15 in group II, 30-40 years had 18 in group I and 12 in group II, 40-50 years had 15 in group I and 16 in group II and 50-60 years had 10 in group I and 12 in group II. In 20 cases in group I and 18 in group II had A3 type of fracture and B2 was seen in 11 and 12 patients respectively. Mode of injury was RTA in 42 in group I and 38 in group II, fall in 10 in group I and 12 in group II and violence in 3 in group I and 5 in group II. Left side was involved in 30 cases in group I and 28 in group II and right side in 25 and 27 in group I and II respectively. Level of injury was upper 1/3rd seen in 16 and 19, middle 1/3rd in 29 and 30 and lower 1/3rd in 10 and 6 patients in group I and II respectively. Range of movement pre- operatively in group I was 8-128 degrees and in group II was 4-130 degrees and post- operatively in group I was 4-134 degrees and in group II was 5-130 degrees. The difference was non- significant (P> 0.05). In 20 cases in group I and 32 in group II DASH score was excellent, 15 cases in group I and 10 in group II had good, 15 in group I and 7 in group II had fair and 5 in group I and 6 in group II had poor DASH score. The difference was significant (P< 0.05). Complications seen were implant failure 1 in group I and 2 in group II, superficial infection 1 in group I and 1 in group II, and deep infection 2 in group I and 1 in group II, non- union 2 in group I and 2 in group II, shortening seen in 1 in group I and 3 in group II. The difference was non- significant (P> 0.05). Conclusion: In the treatment of humeral shaft fractures, both humeral interlocking nails and dynamic compression plating might be taken into consideration.
