60 year old male tripped in his house 4 weeks ago and suffered a laceration over the anterior tibia. A week later the wound was not healed and he had pain and swelling over the anterior tibia. He is a smoker, obese, and has Type II DM. The wound still is not healed and he has had two separate surgeries for wound management. He now complains of a deep dull ache from the mid leg down to his ankle. Radiographs were obtained.
What are the findings?

I see something in his medial malleolus (first film) that appears to be a non-displaced fracture, but cannot see it in the 2nd film. Given his history of diabetes and poor wound closure, osteomyelitis comes to mind as well. Interesting case! :)

Hey Chris, I think what you are seeing is the overlying fibula. The osseous structure look ok to me, except a small ovid lucency at the medial malleolus (not concerning) however there is a soft tissue abnormality anterior to the tibia. Infection.

Osteomyelitis sounds about right. Ws there any fever involved a well? Periosteal reactions and soft tissue component (cloudiness of radiograph) as well.

UTDC,
Thanks for correcting my apparent oversight. After looking at it again, I agree with you. I still think the OM may be an issue. Judging by these films, if it is OM then it's quite early because there are no visible (at least to me) periosteal reactions, but these may be better seen via CT or bone scan.

I see no evidence of osteomyelitis. The only abnormality I see is in the soft tissues. It is probably necrotizing fasciitis...just kidding. In any case, I'm sure Dr. Wagner could give us some valuble input on this one.

I think evolving osteomyelitis and compartment syndrome are very reasonable, taking into account the limited history and films that are presented here. The fibula is completely normal in these projections.
As an aside, as you know the 5 'P's' of Volkmann's ischemia might also apply on clinical exam: -pulselessness -pain (earliest sign of compartment syndrome) -paresthesia -pallor -paralysis

I don't see any signs of OM in this radiograph. Sure the patients history and presentation would lead my thoughts in that direction but there still appears to be pathology in the distal tibia. I don't think it is in the medial malleolus however but it does present (and appear) to resemble a Tillaux Fracture. Even though this is primarily an adolescent condition, I don't think it would be an unreasonable occurrence given this patients age and history.

Differentially I may also consider fracture of the Posterior malleolus (a.k.a. posterior articular margin) which may be more likely going by the size of the fx. and patients age.

FINDINGS: AP and lateral views of the left tibia and fibula were obtained. A lucent soft tissue defect is noted along the anterior leg in the mid to lower region. The distal tibia has an irregularly linear lucency measuring 3.4 cm in length, extending to the articular surface. There is intermixed lucency and sclerosis along the medial malleolus and distal tibial metaphysis. Diffuse soft tissue swelling is present.
IMPRESSION: Findings in the distal tibia are concerning for osteomyelitis. A soft tissue ulcer is noted in the mid to distal anterior leg.
