A rare deformity of the fifth finger
Kirner's deformity is a rare musculoskeletal disorder characterized by a progressive curvature of the distal phalanx of the fifth finger (little finger) in a palmar and radial direction. This condition is typically observed in children and adolescents and is often bilateral.
Presentation[edit]
Kirner's deformity usually presents during childhood or early adolescence. The deformity is characterized by a painless, progressive curvature of the distal phalanx of the little finger. The curvature is typically directed towards the palm and the radial side of the hand. In most cases, the condition is bilateral, affecting both hands.
Etiology[edit]
The exact cause of Kirner's deformity is unknown. However, it is believed to have a genetic component, as it can occur in families. The condition is often associated with autosomal dominant inheritance patterns, although sporadic cases have also been reported.
Pathophysiology[edit]
The pathophysiology of Kirner's deformity involves abnormal growth of the distal phalanx of the fifth finger. This abnormal growth leads to the characteristic curvature of the finger. The underlying bone may show changes such as sclerosis and irregularity, which can be observed on radiographic imaging.
Diagnosis[edit]
Diagnosis of Kirner's deformity is primarily clinical, based on the characteristic appearance of the finger. X-ray imaging can be used to confirm the diagnosis and assess the extent of the deformity. The X-ray typically shows a ventral and radial curvature of the distal phalanx with possible bone changes.
Management[edit]
In most cases, Kirner's deformity is a benign condition that does not require treatment. However, if the deformity is severe or causes functional impairment, surgical intervention may be considered. Surgical options include corrective osteotomy or epiphysiodesis to straighten the affected phalanx.
Prognosis[edit]
The prognosis for individuals with Kirner's deformity is generally good. The condition is usually painless and does not progress to cause significant functional impairment. In cases where surgery is performed, the outcome is typically favorable with improved finger alignment.
