Elective: Fracture Immobilization
Elective adaptation of: Immobilization of suspected fractures in the lunar environment, where casting technique and weight-bearing principles differ from Earth.
Indications
Suspected or confirmed fracture, dislocation pending reduction.
Contraindications
Open fracture (special management — do not cover wound with cast). Neurovascular compromise (emergency orthopedic consultation).
Equipment Required
Standard Equipment
SAM splint or plaster/fiberglass casting material, padding, elastic bandage, sling.
Lunar Medical Bay Substitutions
Standard plus: SAM splints (preferred over traditional casting — moldable, reusable, can be applied in suit). Thermoplastic splint material (moldable in hot water, sets rigid — excellent for lunar medical bay). Air splints (caution: pressure changes with altitude/suit pressure).
Procedure Steps
Assess neurovascular status. Analgesia. Align fracture (if significantly displaced and trained). Apply padding. Mold splint to fracture pattern. Secure with elastic bandage. Reassess neurovascular status.
Lunar Technique Modifications (1/6 Gravity)
LUNAR FRACTURE MANAGEMENT: In 1/6g, weight-bearing is already reduced — some fractures can be managed non-operatively that would require surgery on Earth. However, bone quality may be poor from osteoporosis. Assess: can the fracture be managed to mission end without surgical intervention? Consult Earth orthopedics via telemedicine. Moonboot for foot/ankle fractures. Modified crutch walking in 1/6g (different technique — moonbouncing with unaffected leg). Traction uncommon in lunar setting.
Telemedicine Guidance Points
Contact Earth Medical Relay (+1.3s delay) at these critical decision points:
All fractures: orthopedic telemedicine consult. Femoral neck fracture: urgent consult (evacuation likely required). Spine fracture: urgent neurosurgery consult.
Training Requirements
All residents: basic fracture splinting. Medical officers: fracture assessment and advanced immobilization.
Possible Complications
Neurovascular injury, compartment syndrome, malunion, non-union in osteoporotic bone.
