The number of surgeries done in a week is variable. It is better to look at overall numbers and variety in programs. As an example, I just spent a year on a moderately busy service with two junior residents, and I logged 200 cases for the year. This was cases that I did not do with the junior resident, and they each probably did just as many. This is also taking into account that we equally shared call (q3 for the year), and call day meant clinic day. This also does not include bedside procedures (lumbar drains, lumbar punctures, ventriculostomy drains). Yet, I have friends in other programs who have done 500 (or more) cases a year. Also, you have to keep in mind the average neurosurgical case is longer than the average general surgery case. I have been in 18+ hour cases, and most spinal instrumentation cases are 3 to 6 hours, as an average. Still, this depends on who you are working with and what cases you are doing. The "bread and butter" resident cases - evacuation of SDH/EDH, ACDF, shunt - are about 1.5 hours - sometimes longer/sometimes shorter. Hope that helps.
