I'm a current resident at UT Southwestern/Parkland. I'll sum up the program briefly and if you have any other specific questions just post and I'll answer them.
Parkland: large trauma referral center (all of north Texas, west Texas, southern Oklahoma). Unlike Houston with a large medical center, almost all trauma feeds into Parkland. Entire new Parkland hospital under construction currently, will be up and running 2015. Largest hospital construction project in country. County hospital for all of Dallas.
UT Southwestern University Hospital: Private hospital affiliated with the University. Great sports experience, total joints. Large joint revision referral center because of Dr. Huo. New hospital under construction, operational in 2016. Large new outpatient surgery center in process of being turned into outpatient orthopaedic surgery center.
Zale-Lipshy University Hospital: another University private hospital. Great hospital, private spine experience.
VA North Texas: similar to VA experience at most other places. Autonomy in the OR, clinics filled with patients awaiting surgery.
Texas Scottish Rite: you work like a fellow for 6 months at one of the top pediatric orthopaedic hospitals in the country, tons of pediatric deformity, spine, hand
Children's Medical Center: work with same faculty as TSRH, pediatric trauma/infection, pediatric sports at new surgery center in North Dallas
Norwich, UK: 3 months spent in England during your 5th year. About 2 hours outside of London. Operate and take call like an attending during the week, time for travel on weekends. Apartment and car covered by program.
Other hospitals: we work at other hospitals throughout Dallas later in the residency with program alumni. Private experiences toward the end of residency to operate and learn about working outside an academic facility.
Administration: recent chair change to Starr - a graduate of UTSW medical school, UTSW residency, UTSW trauma fellowship. Knows and loves the residency and Parkland. One of us. Well-published, respected, great mentor and surgeon. Program director Gill is spine, great resident advocate.
Overall Pros: residents are all close - there are 30 of us and we all know everyone else's entire families. We eat dinner together with faculty multiple times a week. No odd ball residents that are unhappy or don't fit in. We start operating early, we have great autonomy in the OR, strong mentors, a large trauma database for research, clinical research easy for all subspecialties, basic science lab with tons of projects ongoing
Honestly I don't think you can go wrong training at any of the hospitals in Texas, but I do think our program is the best the state has to offer.
