Review Case Reports
Management of large peripheral nerve defects with autografting.
A segmental nerve defect from trauma results in significant loss of function of the extremity, and rarely occurs in isolation. Autografting of the nerve defect is the current gold standard. ⋯ Nerve grafting for segmental nerve injuries continues to be an essential and appropriate treatment.

There is currently a lack of agreed criteria for sonographic assessment of callus and reliability between reviewers. The primary aim of this study was to determine criteria and reviewer agreement for sonographic bridging callus (SBC) on ultrasound. The secondary aim was to analyse the use of ultrasound to detect bridging callus in a prospective cohort of patients with a conservatively managed clavicle fracture. ⋯ This is the first study to establish time specific ultrasound fracture findings with a repeatable technique and assess the agreement between blinded reviewers.

Elbow flexion is the first goal in upper partial brachial plexus palsy treatment. However, elbow extension is essential for daily living activities. To recover this function, one fascicle of ulnar nerve can be transferred to the branch of the long head of the triceps, but this procedure has been previously published in only two patients. ⋯ Because the harvested ulnar nerve motor fascicle is close to the branch of the long head of the triceps, the recovery time for this procedure is shorter than that of other described nerve transfers. The isolated recovery of the reinnervated long head of the triceps muscle excludes spontaneous recovery occasionally noted in upper root plexus injuries. The transfer of one fascicle of ulnar nerve to the branch of the long head of the triceps is reliable for active elbow extension recovery in C5, C6 and C7 brachial plexus palsies.

Multicenter Study Comparative Study
The medial femoral condyle free corticoperiosteal flap versus traditional bone graft for treatment of nonunions of long bones: a retrospective comparative cohort study.
Fracture healing is a complex process and many factors change the local biology of the fracture and reduce the physiologic repair process. Since 1991 the free vascularised corticoperiosteal graft has been proposed to treat nonunions. In this study we compare the healing rate and the healing time of the free vascularised corticoperiosteal graft harvested from medial femoral condyle versus the traditional cancellous bone graft from the iliac crest combined with other biologic or pharmacologic factors. ⋯ Some studies describe a high healing rate of recalcitrant nonunions with treatments different from vascularized bone flaps: it is difficult to compare the results of vascularized bone transfers with the results of other case series. Our groups are very homogeneous even if it is difficult to define correct inclusion criteria because there is still no agreement about what is defined a recalcitrant or difficult nonunion, and the number of trials of previous surgery before to perform a vascularized free flap. Even if our study cohort is small, we have demonstrated that the MFCCF generally seems to give a better healing chance with a shorter healing time compared to other treatments.
