1cm proximal to the fibula and 2cm superior aspect of the calcaneus. 45 degree angle to the plantar surface of the foot.
200
one relative contraindication to primary repair of the spring ligament
long-standing rupture composed of degenerated ligament tissue
200
Indication for an Evans
symptomatic subfibular or sinus tarsi impingement
300
5 Clinical findings that indicate a tenosynovectomy
1. Palpation over the posterior tibial tendon
2. Strength test normal
3. single heel rise can reproduce pain
4. no hind-foot valgus
5. no forefoot abduction
300
What are the 2 criterial that must be meet so an FDL transfer is funstional
1. STJ inversion 15 degrees
2. 10 degrees of adduction at the transverse tarsal joint.
300
What are the Biomechanical purposes of a calcaneal osteotomy.
1. shifts the mechanical pull of the achilles tendon medially
2. shifts the weight bearing axis of teh heel closer to the long axis of the tibia.
300
easiest and strongest method of repair of the spring ligament
transverse incision of the ligamnet without excising the redundant tissue and repair with pants over vest suture
300
what is clinically noted for a cotton to be performed
rigid elevated first ray after correction of the STJ in neutral
400
describe the incision for tenosynovectomy.
Incision is from the navicular insertion to approximately 4cm proximal to the tip of the medial malleolus.
400
What patient group do you perform a side-to-side tenodesis with the proximal portion of the PT and FDL
Younger pt with systemic or traumatic conditions of the PTT
400
orientation of the osteotomy
perpindicular to the long axis of the calcaneus
400
What is used to reconstruct the spring ligament
Peroneus longus tendon
400
descirbe the osteotomy for a evans
10mm proximal to the calcaneocuboid joint
500
complications of tenosynovectomy
infection
Nerve damage
Wound necrosis
progression of deformity and tendon disease
DVT
500
What is the appropriate tension placed on the FDL during a transfer
Half way point of full adduction and Inversion and when all tension is released from the FDL
500
what is the most common nerve injuried (Be specific)
calcaneal sensory branch
500
True or False the reconstruction of the spring Ligament discribed reconsturcts only the superomedial component
False
500
what has a higher rate of union evans or calcaneocuboid distraction arthrodesis
