Abstract
BACKGROUND: Transfer fractures in the lower limbs of bedridden and chair-bound nursing home patients can result from trauma induced by the usual lifting, moving, turning, or transferring maneuvers. Treatment entails immobilization for pain control and position change; however, splints/hard casts increase the risk of pressure sores. Therefore, we evaluated the use of a sponge cast. MATERIALS AND METHODS: Between March 2011 and October 2017, 17 patients with a lower limb transfer fracture due to transferring maneuvers in a nursing home were recruited. We evaluated the improvement in pseudo-motion and divided the patients as having bony union, fibrous union, or remaining pseudo-motion. We also investigated the occurrence of pressure sores due to immobilization up until the final follow-up. RESULTS: Femur fractures occurred in 15 patients and lower leg fractures in two. Six of the 15 femur fractures were periprosthetic (four hip arthroplasty and two knee arthroplasty). Pseudo-motion was improved in 15 of 17 cases, within an average of 17.3 weeks for the improvement (14-23 weeks; bony union: 11 cases and fibrous union: four cases). Pseudo-motion remained in two cases: one periprosthetic fracture around the knee arthroplasty and the other, a femur neck fracture. No pressure sores occurred. CONCLUSIONS: A sponge cast appears to be one of the effective treatment options available for bedridden or chair-bound patients with a lower limb fracture due to its low risk of complications and satisfactory clinical results.
