Module 14, General Medical Level

This patient is a 14 year old boy who presented complaining of pain
in his right leg for 9 months and a contracture of the right knee which
has developed over this period. There is no history of significant trauma.
He was born 3 weeks premature with bilateral renal hypoplasia and a seizure
disorder. Three renal transplants have failed and he currently receives
peritoneal dialysis four times a day. Stunted growth and developmental
delays during childhood include short stature, standing at 16 months and
walking at 2 years. He sustained a right tibia and fibula fracture 6 years
prior to presentation after minimal trauma. On physical examination he
was noted to have poor dentitia, right knee 15 degree flexion contracture,
painful ROM of right hip and knee.
Question 14A

This knee problem is due to his chronic renal failure.
Question 14B

An
important blood test to order is a serum calcium level.
Question 14C

Because
he is developing a knee flexion contracture he should be referred to physical
therapy to work on a stretching program so this contracture does not get
worse.
Question 14D

This
boy needs to have x-rays of the hip, because the hip deformity causes even
more long term disability than the knee complaints.
Question 14E

This
bone problem is largely non-reversible and he will have life long bone
weakness.
