A hammer toe or contracted toe is a flexion deformity of the proximal interphalangeal (PIP) joint of the second, third, or fourth toe, causing it to be permanently bent.
Planning
Indications
Imaging is not necessary for clinical diagnosis.[1] Its main uses are in detecting any alternative or synchronous diagnoses, as well as surgical planning.[1]
Procedure
Weightbearing dorsoplantar and lateral projections.[1]
Evaluation
- Look at joints for erosions, suggesting arthritis.[1]
- Look at the metatarsophalangeal (MTP) joints for any varus angulation and/or dorsal subluxation or widening of the joint sace, suggesting MTP instability.[1]
- Detect any bunion[1] (see X-ray of bunion)
- X-ray of Freiberg disease.jpg
Also look at the metatarsal heads, particularly for enlargemet and osteophytes, suggesting Freiberg disease (pictured)
- X-ray of flexion angle of proximal interphalangeal joint of second toe.jpg
Measure the flexion angles of suspected involved toes only if requested by the referring doctor. This case is a normal foot, with flexion angle of the second toe PIP joint.
Report
- Flexed PIP joints and in which toes, but give angles in numbers only if the degree of deformity is requested by the referral, since it is not a reliable basis for diagnosis.
- Absence or presence of other deformities.
