Objectives: To study delayed primary closure in ballistic and explosive device injuries by describing the clinical, therapeutic and evolutionary aspects. Methodology: This was a prospective study running from August 1, 2022 to May 31, 2023 including all patients of all ages presenting a ballistic or explosive device injury. Results: In 10 months, we collected 190 cases of ballistic and explosive device trauma, or 35.9%. The average age was 31.89 ± 14.026 years with a sex ratio of 12. Intercommunity conflicts were the most frequent causes (61.1%). Limb injuries represented 78.9 %, of which isolated wounds without fracture were the most frequent (59.5%). Standard radiography was ’the most used medical imaging (94%). DPC (Deferred Primary Closure) was performed in 71.2% followed by DPC + external fixator in 19%. We recorded 2 cases of death. Conclusion: Well-conducted delayed primary closure helps reduce the risk of complications, give the patient every chance of survival and shorten the hospital stay.
