AbstractIn this study, we report the outcome for spontaneous recovery of elbow flexion in obstetric brachial plexus injury managed without nerve reconstruction. Excluding those with transient paralysis, our records revealed 152 children with obstetric brachial plexus injury born before our unit routinely offered brachial plexus reconstruction. Five had had nerve repairs. Of the remainder, only one patient had insufficient flexion to reach their mouth. Elbow flexion started to recover clinically at a mean age of 4 months for Narakas Group 1, 6 months for Group 2, 8 months for Group 3 and 12 months for Group 4. The mean active range of elbow flexion, in 44 cases, was 138°. The mean isometric elbow flexion strength, in 39 patients, was 63% (range 23%-100%) of the normal side. It appears to be rare for elbow flexion not to recover spontaneously, although recovery occurs later in more severe injuries. It is doubtful if nerve reconstruction can improve elbow flexion above the likely spontaneous recovery in babies with obstetric brachial plexus injuries.
