Background Groin pain after total hip arthroplasty (THA) or total hip resurfacing arthroplasty can be troubling for patients and surgeons. Potential sources of pain include infection, loosening, metal hypersensitivity, or impingement of bony structures or the iliopsoas tendon. Questions/purposes We compared the rate of groin pain after THA or hip resurfacing using metal-on-metal to those of other bearing surfaces. Methods We identified 347 (334 patients) primary total hip (n = 301) or resurfacing (n = 46) arthroplasties. Complete preoperative, operative, and postoperative data were available for 282 hips. We retrospectively reviewed the charts for the presence or absence of groin pain at a minimum of 1 year after surgery with a specific focus on etiologic factors. The minimum followup was 12 months (mean, 14 months; range 12 to 24 months). Results The rate of groin pain was 7% (15 of 217 patients) after THA with conventional bearing surfaces, 15% (4 of 26 patients) with metal-on-metal THA and 18% (7 of 39 patients) with total hip resurfacing. Younger patients were more likely to report groin pain postoperatively and more likely to have metal-on-metal bearing surfaces.Conclusions Our data at short-term followup suggest increased rates of groin pain after metal-on-metal THA or resurfacing arthroplasty versus THA using polyethylene or ceramic bearing surfaces. The reasons are not clear but they appear to be associated with younger age. Potential factors include impingement, activity level and possibly higher expectations for patients receiving metal-on-metal bearing surfaces that may make those patients more likely to report postoperative pain.

Interprofessional education (IPE) in clinical practice is believed to improve outcomes in health care delivery. Integrating teaching and learning objectives through cross discipline student interaction in basic sciences has the potential to initiate interprofessional collaboration at the early stages of health care education. Student attitudes and effectiveness of IPE in the context of a combined gross anatomy course for first-year students in Doctor of Physical Therapy (DPT) and Doctor of Medicine (MD) degrees curricula were evaluated. Integrated teams of MD and DPT students participated in part of the gross anatomy dissection course at Mayo Medical School. A survey was administered to 42 MD and 28 DPT students that assessed their attitudes toward IPE and cooperation among health care professionals. Pre- and post-experience surveys were evaluated. Positive comments were related to opportunities for developing a better understanding of the nature and scope of each other's programs, encouraging teamwork and communication, mutual respect, and reducing the perceptual divide between disciplines. Ninety-two percent of the students agreed that interprofessional learning would help them in becoming a more effective member of the health care team. This initial experience with IPE in gross anatomy provides a basis for continued development of interdisciplinary educational strategies.

At 5 years, young athletes with LROM of the hip showed increased progressive degenerative changes on MRI and radiographs compared with matched controls. Although the majority of these participants remained asymptomatic, those with features of FAI had radiographic findings consistent with early osteoarthritis. These outcomes suggest that more aggressive screening and counseling of young active patients may be helpful to prevent hip osteoarthritis in those with FAI.

Objective: To compare functional and clinical outcomes in patients with pertrochanteric hip fractures treated with either a short (SN) or long (LN) cephalomedullary nail. Design: Prospective, randomized. Setting: Clinical investigation was performed at the Mayo Clinic's Level 1 Trauma Center in Rochester, MN. Patients/Participants: Two hundred twenty patients with intertrochanteric fractures were prospectively randomized to an SN or LN cohort. A total of 168 patients (SN, n = 80; LN, n = 88) had a mean follow-up of 13.9 months. Fifty-two patients did not meet the minimum 3-month follow-up. Demographics were comparable between the cohorts. Main Outcome Measures: The primary outcome measurement was functional outcome evaluated by Short Form (SF-36) and Harris Hip scores (HHS) at 3 months. Secondary outcomes included implant failure, peri-implant fracture, mortality, operative time, estimated blood loss, and reoperation. Results: SN and LN cohorts were comparable in all aspects of the SF-36. There was a clinically insignificant difference in the HHS between cohorts. Patients treated in the SN cohort experienced shorter operative times but did not differ in tip-to-apex distance or subtrochanteric fracture extension. There was no difference in implant cutout, deep surgical site infection, or peri-implant fractures. Conclusions: Patients treated with SNs or LNs for pertrochanteric femur fractures experienced comparable functional outcomes as measured by SF-36 and HHS. When compared with the LN cohort, SN patients experienced no difference in peri-implant fracture or lag-screw cutout and tolerated up to 3 cm of subtrochanteric fracture line extension.
