Abstract:

BACKGROUND: Swan-like memorably-compressive connector (SMC) has received good efficiency in clinical application, and appears with new phenomenon of bone healing with no callus and no stress-shielding.
OBJECTIVE: To electrometric analyze the clinical application of SMC.
METHODS: Load-strain curve was obtained by sticking slice and standardization, then according to the strain value showed by strain gauge when the fresh humerus was fixated by SMC, the value of dynamic memorial force for holding bone was calculated.
RESULTS AND CONCLUSION: The swan-neck compressive part, swan-body connective part, swan-wing holing part of the SMC were harmonized with each other, biological force values of the dynamic memorably holding the bone was 110.35 N. It is indicated that SMC has the dynamic memorably holding force providing guarantee for promoting external fixation removal, postoperative functional exercises and limb rehabilitation.
