[Neonatal traumatic epiphyseolysis of the humeral head. A rare occurrence].

Neonatal traumatic epiphyseolysis of the humeral head is rare, and only a few cases are reported in the literature. We present a case of a 13-day-old female newborn with malposition and relaxation of the left upper limb. The clinical examination showed distinct range of motion particularly for abduction. Magnetic resonance imaging (MRI) indicated epiphyseolysis of the humeral head. Closed reposition followed by immobilisation was done. The following MRI showed correct axis with adaption of the humeral head. Later, malposition of the axis with angulation in the ventromedial position was seen. This status was not followed by renewed repositioning. The x-ray examination 5 months later and MRI 9 months later showed a centered position of the epiphysis. In conclusion, neonatal traumatic epiphyseolysis of the proximal humeral head occurs rarely but should be considered, particularly with unclear relaxation of the limb.
