Mobiloblast - An Emerging Societal Menace.

Background: In 50 years since mobile phones were invented, their number has surpassed the global population, with India being the second-largest user after China. Although the lithium-ion battery failure rate is 1 in 10 million, high production increases related injuries. This study presents a series of hand injuries caused by mobile phone battery explosions at a tertiary care centre in central India. Methods: A retrospective audit was conducted at our institute from January 2020 to March 2024. Medical records were reviewed for demographics, clinical history, management and postoperative complications. Hand function was assessed at a minimum of 6 months post-op using the Michigan Hand Outcomes Questionnaire (MHQ). Spearman's correlation test was used for statistical analysis using Jamovi Statistical software. Results: Twelve patients (mean age: 24.8 years, range: 8-55) with lower and middle socioeconomic backgrounds were included. Paediatric cases resulted from playing with discarded batteries, while adult cases occurred during charging. Nine (75%) patients had dominant hand involvement, one (8%) had a non-dominant hand injury and two (17%) had bilateral injuries. Injuries were classified as mild (three patients, 25%), moderate (two patients, 16%) and severe (seven patients, 58%). MHQ scores averaged 80.7 for mild, 68.5 for moderate and 52.9 for severe injuries. Statistical analysis showed an inverse correlation between injury severity and hand function (rho = -0.809, p < 0.005). Conclusions: Mobile phone battery explosions pose a growing health hazard, causing severe trauma. Most cases are preventable through proper disposal of electronic waste and discarded batteries. Awareness and adherence to safe practices are essential for reducing such injuries. Level of Evidence: Level IV (Therapeutic).
