COMPENSATIONS

Question 1

normal compensation for a plantar flexed 1st ray is to dorsiflex it

in rigid plantarflexion of the 1st ray, the 1st ray cannot dorsiflex to any great extent

• results in greater pressure sub 1 during gait
• will see calluses sub 1 and 5 very frequently

Answer 1

dorsiflexion of the 1st ray

Question 2

another compensation that will be seen with rigid plantar flexed 1st ray is an attempt to supinate the LMTJ
-but the deformity is rigid so no supination can take place at the LMTJ

Answer 2

pronation of the LMTJ

Question 3

since the foot can’t supinate at the LMTJ due to rigid plantarflexion, the STJ will supinate as opposed to pronate during the contact period of the stand phase

Answer 3

supination of the STJ

Question 4

secondary to pronation at LMTJ due to rigid plantarflexed 1st ray and the supinated STJ

• OMTJ follows STJ in gait
• mets plantar flex and adduct on the rearfoot

Answer 4

supination of the OMTJ

Question 5

relative dorsiflexion at ankle due to the calcaneus being forced to dorsiflex by the forefoot

• LMTJ pronated, STJ and OMTJ supinated
• seen in cavus foot

Answer 5

dorsiflexion of ankle joint

Question 6

what is the gait analysis?

Answer 6

foot doesn’t pronate at STJ during stance phae but remains supinated throughout contact and midstance like cavus foot
