CHAPTER 44: Thigh, Leg, and Foot Lacerations Flashcards
TRUE or FALSE?
Compartment syndrome is a rare complication of thigh wounds
TRUE
Compartment syndrome is a rare complication of thigh wounds
Broad internal fibrous arch which helps maintain the shape of the heel
Inner cup ligament
The tendon which is the primary contributor to foot plantar flexion
Achilles tendon
Injuries to these nerves may result in toe clawing
Posterior tibial nerve & Deep peroneal nerve
TRUE or FALSE?
Exploration should be limited on infected wound on the weight- bearing plantar surface with suspected foreign body
FALSE
The dense tissue of the plantar surface of the foot limits wound visualization, and the risk of creat-ing further injury limits exploration. An exception to this general rule of limited exploration on the weight-bearing plantar surface is in an infected wound with suspected foreign body.
Two-point discrimination varies in the foot
Hind, mid, and forefoot: 1.5cm
Big toe: <1cm
Two-point discrimination varies in the foot
Hind, mid, and forefoot: —?— cm
Big toe: —?— cm
Test wherein patient lies prone on the examination cart with the feet hanging over the edge of the bed, and the examiner places one hand on each mid-calf
Thompson test
Positive= foot plantar does not flexes when the calf is squeezed
Test that assist in detecting an Achilles tendon rupture
Thompson test
Positive= foot plantar does not flexes when the calf is squeezed
TRUE or FALSE?
No single imaging modality or wound exploration will identify every foreign body.
TRUE
No single imaging modality or wound exploration will identify every foreign body; emphasize close follow-up if the mechanism of injury sug-gests a potential for a foreign body but none was identified on imaging or wound exploration.
A definite imaging sign of joint penetration
Intra-articular gas on plain radiograph
If the radiograph does not display intra-articular gas,this test can be used to determine joint integrity, especially in the knee and ankle
Saline load test
SN of ≥95%: 74 to 194 mL (knee) & 30 to 55 mL (ankle)
TRUE or FALSE?
The addition of methylene blue in saline load test increases diagnostic accuracy.
FALSE
The addition of methylene blue in saline load test does not increase diagnostic accuracy.
TRUE or FALSE?
Epinephrine containing local anesthetics can be safely used for digital blocks in toes.
TRUE
Epinephrine containing local anesthetics can be safely used for digital blocks in toes.
Are the two most commonly used nerve blocks for the foot
Sural nerve block & Posterior tibial nerve block
TRUE or FALSE?
Wound repair has lower risk of infection within 6 hours after injury
FALSE
A lower risk of wound infection if the repair is performed within 6 hours after the injury is not substantiated by published evidence.
