Presentation
Swelling and pain in the volar aspect of the mid to distal forearm. Patient had a background of wood splinter injury 2-3 months previously.
Patient Data
There is soft tissue swelling in the volar aspect of the distal forearm.
Linear echogenic focus (~33 mm long) at site of clinically visible swelling - wood splinter in flexor digitorum superficialis muscle belly. There are two other wood splinters (each about 10-12 mm long) and few smaller ones (each < 5 mm long) near distal end of abovementioned larger foreign body. Collection around these foreign bodies, causing clinically visible swelling.
Another wood splinter (~30 mm long) just proximal to abovementioned foreign body deeper in flexor digitorum superficialis muscle belly. Granuloma measuring ~15 x 10 mm around this last foreign body extending to flexor digitorum profundus muscle.
Median and ulnar nerves are normal. Ulnar and radial arteries are patent.
Intra-operative photos showing the wood splinters. The distal splinter was more superficial and the more proximal splinter was deeper.
Two longer/larger and several other smaller wood splinters.
