Collateral ligament injury of finger

Case contributed by Dr Nafisa Shakir Batta

Presentation

Cricket injury with swelling and instability at index finger and partial flexion deformity at proximal interphalangeal joint.

Patient Data

Age: 28 years
Gender: Male
Modality: MRI

MRI study of the proximal interphalangeal joint of index finger reveals interstitial edema and mild thickening at ulnar and radial  collateral interphalangeal ligaments ( sagittal retinacular ligaments) suggesting sprain injury, a little more prominent at radial aspect. Some soft tissue edema is appreciated at the volar plate.

The central and lateral bands of extensor indicis are normal. Bone anchors are seen at base of middle phalanx of fifth digit.

 

 

Case Discussion

MRI findings are consistent with partial tear at collateral interphalangeal ligaments with soft tissue thickening at volar plate of PIP joint of right index finger. This may lead to instability if left untreated.
