Radiocarpal rotatory subluxation is a rare but debilitating wrist injury. It often occurs after significant trauma, such as a bicycle fall or high-energy impact. This specific case highlights an anterior subluxation associated with a small radial styloid/rim avulsion. While initial radiographs may appear subtle, clinical symptoms are often severe. Consequently, clinicians must maintain a high index of suspicion for this injury pattern.
Diagnosis remains challenging because standard X-rays do not always reveal the full extent of carpal displacement. However, further imaging is essential when physical findings do not match radiographic evidence. CT scans provide a more detailed view of small avulsion fractures and rotational malalignment. Therefore, physicians should order advanced imaging early to avoid delays in treatment. Early detection directly impacts the success of subsequent interventions.
Timely surgical fixation is the gold standard for restoring hand function. In this case, surgeons successfully reduced the subluxation and secured the radial styloid avulsion. This approach stabilizes the joint and allows for early rehabilitation. Remarkably, the patient achieved a full recovery within three months. This outcome proves that aggressive management of radiocarpal rotatory subluxation can restore high levels of functionality.
This injury typically results from high-energy trauma, such as falling from a height or a bicycle. The mechanism involves extreme rotational forces combined with axial loading on the wrist.
Initial radiographs might only show subtle malalignment or small \"fleck\" fractures. Without a CT or MRI, the true degree of carpal rotation and subluxation can remain hidden.
With prompt surgical intervention and physical therapy, many patients restore hand function within three to six months. However, delays in diagnosis can lead to chronic instability or arthritis.
