Delayed lesions of the femoral or sciatic nerve are a rare complication

after total hip arthroplasty. Several cases in association with cement

edges, scar tissue, broken cerclages, deep hematoma, or reinforcement

rings have been published.We report about a 62-year-old female who

developed a pure motor paresis of the quadriceps muscle 2 weeks after

total hip arthroplasty. After electrophysiological evaluation had

revealed an isolated femoral nerve lesion, revision of the femoral nerve

was performed. During operative revision no pathologic findings could be

seen. One week later the patient developed paralysis of the left wrist

and finger extensors after using crutches. Electrophysiological

evaluation revealed several nerve conduction blocks in physiological

entrapments and the diagnosis of hereditary neuropathy with liability to

pressure palsies (HNPP) was established.Hereditary neuropathy with

liability to pressure palsies (HNPP) is a rare disease with increased

vulnerability of the peripheral nerve system with mostly reversible

sensorimotor deficits. It should be taken into consideration in cases of

atypical findings of compression syndromes of peripheral nerves or

delayed neuropathy, e. g., after total hip arthroplasty.

Gretchen: You're the " cat's meow " ! Marry me and take me away from all this!

Thanks a ton for posting the HNPP research information. Finding HNPP scientific

info other than " old rhetoric " has been limited in my searches. The marriage

offer is still on! More, more, more! LOL Of course you'd have to bring your

own wheelchair and a fast one at that if you're to keep up with me.
