Health-related quality of life in patients with transtibial amputation and reconstruction with bone bridging of the distal tibia and fibula

Abstract

Background: Bone-bridging (arthrodesis of the distal tibia and fibula) at the time of transtibial amputation is a controversial operative technique that is anecdotally reported to improve the weightbearing capacity of the residual limb and to decrease residual limb discomfort.

Methods: Thirty-two consecutive patients with multiple diagnoses had transtibial amputation with a distal tibial-fibular bone-bridge, all done by a single surgeon (MAP). At an average of 16.3 months after surgery all patients completed the Prosthetics Evaluation Questionnaire (PEQ), a validated outcomes instrument specifically created to evaluate quality of life and functional demands in patients with a lower extremity amputations. Their responses were compared with those of 17 preselected, highly functional transtibial amputees from two academic medical centers who previously had transtibial amputations using a traditional non bone-bridge operative technique; their time since amputation averaged 14.7 years.

Results: The "nonselected" consecutive patients with a bone-bridged residual limb scored higher (more favorable) in the Ambulation (p = 0.037) and Frustration (p < 0.001) domains of the PEQ and lower (less favorable) in the Appearance (p = 0.025) subscale. Their scores were similar in the other six domains.

Conclusions: Patients of multiple ages with multiple diagnoses who had bone-bridging of the distal tibia and fibula at the time of transtibial amputation had scores on a validated outcomes instrument that were better than or comparable to those of a selected group of highly functional transtibial amputees. The results of this study suggest that bone-bridging at the time of transtibial amputation may enhance patient-perceived functional outcomes.
