in 2013, in which a 19-year-old man who had undergone surgery for a left wrist injury 12 months later presented with loss of internal and external rotation. The first such case of Galeazzi aequivalent fracture dislocation was reported by Jones et al. The X-ray showed that the distal ulna was shortened and bifurcated, but the ulnar bifurcation was atrophied and smaller than previously, the ulnar styloid process was deformed and enlarged, the inferior ulnar radial joint was dislocated, the distal ulna did not participate in the composition of the radial carpal joint, and there was no obvious deformity of the radius. However, there was mild pain around the ulnar styloid process on extreme posterior rotation of the left wrist. A physical examination revealed that the length of the forearms were equal, the left elbow joint was normal, the left wrist deformity was minimal, the left ulnar styloid process was not prominent, there was no obvious local tenderness, the left wrist extension and flexion and rotation range of activities were normal. The patient’s left wrist function recovered satisfactorily and did not interfere with his daily life or physical activity, including playing basketball, push-ups and lifting heavy objects. At the last follow-up, the patient’s status was that of a university student, not yet in the workforce. The patient presented to our hospital at 3 years (Fig. The x-ray showed that the distal ulnar bifurcation was still visible, but the two bifurcated ulnae were close to each other and the base was decreased compared with that at 2 months after injury (Fig. Examination showed that the showed that the pain in the left upper ulnar radius had almost disappeared and the rotation of the left wrist had improved, but there was still pain on extreme supination. After a period of seven months, the patient returned to us as a result of experiencing pain. Consequently, we recommended functional exercise and regular follow-up to manage the condition. Following a discussion, the patient’s parents declined surgical treatment. The patient exhibited normal wrist flexion and extension, but had limited rotation. The new ulna grew inwards, was slightly smaller than the original ulna and did not have a complete articular surface, while the normal original ulna protrudes dorsally and laterally with an intact articular surface and a “Y” shaped distal ulna. With the consent of the patient’s family, we performed a CT examination of the area which clearly revealed the deformity was more clearly (Fig. We performed an X-ray of the injured site and found that the distal left ulna was split and a new ulna was growing. In the present report, the patient was treated for bifid ulna conservatively and followed up for 7 years, hence our case presents the entire progression of the patient who received conservative treatment, which is now functioning normally in the wrist. and was successfully treated via surgical operation. The first case was reported in 2013 by Jones et al. Here, we report a case of an abnormal distal ulnar bifurcation after trauma with a “Y” shape on imaging. Some small epiphyseal injuries may be difficult to detect using imaging techniques and are often overlooked. This Galeazzi aequivalent fracture in fact represents a Salter Harris type I or II (or in rare instances a Salter -Harris type IV) injury. In children or adolescents, Galeazzi equivalent fracture dislocation manifests as distal ulnar epiphyseal separation rather than true distal radial ulnar dislocation (DRUJ). Galeazzi aequivalent fracture dislocation is a compound injury that comprises fractures of the distal third of the radius and dislocation of the distal radial ulnar joint (DRUJ), which is prevalent among adults. Conservative treatment can be applied to avoid the trauma associated with surgery especially in the absence of severe joint mobility impairment with good outcomes. Ulnar diaphyseal fracture may occur in children or adolescents due to injuries, and may be accompanied with manipulation and repositioning. A follow-up performed over the years demonstrated that the patient recovered well, and had normal wrist movements without significant pain, and the patient expressed great satisfaction. In this case report, we describe an 11-year-old male child who presented with an ulnar bifida following trauma to the hand, and was treated with manipulation and conservative treatment without surgery. In previous similar reports, patients were effectively managed through surgery. Clinically, this condition is rare and often leads to distal ulnar bifurcation. Galeazzi fracture dislocation is a compound injury that encompasses fractures of the distal third of the radius and dislocation of the distal radial ulnar joint (DRUJ).
