This is a single-center prospective observational study comparing two techniques for reconstructing bone loss in the lower limbs. The aim of the study was to compare the results of reconstructions using the Masquelet technique with reconstructions using electromagnetic transport nails. The primary endpoint was time to bone healing. This study is the first prospective descriptive study of electromagnetic transport nails.

Rate of radiological consolidation
Radiological consolidation is defined by an anteroposterior and lateral radiograph showing at least three out of four cortical plates consolidated. This assessment is performed during follow-up by the physician treating the patient and will be confirmed by an evaluation committee at a later stage.
Functional outcomes : score MSTS
Functional recovery assessed using MSTS (Musculoskeletal Tumor Society Score). It is composed of 6 items , each item on a scale of 0 to 5, with a higher score indicating better function. The total score, ranging from 0 (maximum disability) to 30 (no disability), can be converted to a point scale from 0 to 100.
Time to full weight-bearing
Time from initial reconstructive surgery to full weight-bearing without assistive devices, as assessed during routine clinical follow-up.
. Functional outcomes : score LEFS
Functional recovery assessed using Lower Extremity Functional Scale (LEFS). It is composed of 20 items , each item on a scale of 0 to 4, with a higher score indicating better function and total score from 0 to 80.
Functional outcomes : paley Marr score.
Functional recovery assessed using Paley-Maar score. This score is defined from "excellent" to "poor"in fonction of pain, autonomous, ....
