Abstract
Fracture patterns in lunar mining injuries differ systematically from Earth equivalents. Lower fall energy but higher equipment mass create distinct injury mechanics. We analyzed 127 fracture cases across five habitats to characterize patterns and inform protective equipment standards.
Mining operations on the lunar surface expose workers to a distinctive injury profile. The combination of lower gravitational acceleration (1.63 m/s²) and heavy equipment creates fall energies that, while lower than Earth equivalents, occur in an environment where bone density is often reduced by prior residency.
Our retrospective analysis identified 127 fracture cases from five mining habitats over 48 months. Distal radius fractures were most common (31%), followed by metatarsal fractures from dropped equipment (24%), and rib fractures from equipment pinning (18%).
A notable pattern: high-energy fractures (from equipment rather than falls) showed more severe comminution than Earth equivalents — the combination of equipment mass and even low-g impact energy exceeds bone strength in deconditioned residents.
We recommend BMD screening before assignment to mining operations and mandatory protective equipment standards for distal extremities.
