Objective To review the advances in the diagnosis and treatment of obstetric brachial plexus palsy (OBPP). Methods The incidence, risk factors, classification, and imaging tests of OBPP and indication, technique, and results of surgery were reviewed and summarized. Results The incidence of OBPP is not declining in recent years. Birth weight of ≥4 kg, forceps delivery, and prepregnancy body mass index of ≥21 are considered to be major risk factors, and caesarean section delivery seems to be a protective factor. Neurophysiological investigations can be applied to qualitative diagnosis of OBPP, but can not to quantitative one. Sensitivity and specificity of both CT and MRI myelography are about 0.7 and 0.97, respectively. Narakas classification is widely used:C5, 6 injury as type I, C5-7 injury as type Ⅱ, C5-T1 injury as type Ⅲ, C5-T1 injury with Horner's syndrome as type IV. It is generally considered that the brachial plexus exploration should be undertaken for infants without spontaneous recovery of elbow flexion by a maximum of 3 months old; and 10% to 30% of patients may need nerve reconstruction surgery. It is advocated that traumatic neuroma of the upper trunk should be resected with nerve reconstruction. The final evaluation for surgical results should be at minimal 4 years for upper roots and 8 years for total roots. Scales of Mallet, Gilbert, and Raimondi are mostly used for assessing shoulder function, elbow function, and hand function. Conclusion Brachial plexus exploration should be undertaken for infants without flexion of elbow at the age of 3 months. Traumatic neuroma (even neuroma-in-continuity) resection followed by microsurgical reconstruction of the brachial plexus is favored.
