RESUMO

OBJECTIVE: To evaluate the effect of warfarin on blood transfusion and postoperative complications in a low-energy hip fracture population compared with a non-anticoagulated comparison group. DESIGN: Multicenter Retrospective Cohort. SETTING: Three Urban Level I Academic Trauma Centers. PATIENTS: Acute, low-energy, native hip fractures in patients 55 years of age or older on chronic warfarin anticoagulation, propensity score matched 1:2 to non-anticoagulated hip fracture patients meeting all other inclusion criteria. MAIN OUTCOME MEASUREMENTS: Transfusion and postoperative complication rates. RESULTS: Two hundred ten anticoagulated hip fracture patients were matched to 420 nonanticoagulated patients. A higher proportion of patients required blood transfusion in the warfarin cohort (52.4% vs. 43.3%, P < 0.001), attributable mostly to the subgroup of patients undergoing arthroplasty. Warfarin patients had higher incidence of overall 90-day complications (47% vs. 38%, P = 0.039) and readmissions (31.4% vs. 8.9%, P < 0.001). Day of surgery international normalized ratio (INR) did not influence transfusions or complications among warfarin patients. Warfarin patients undergoing surgery within 24 hours had no difference in transfusions and had fewer complications compared with those undergoing surgery after 24 hours. On multivariable logistic regression analysis, warfarin use and day of surgery INR were not predictors of transfusion or complications. CONCLUSIONS: Patients on warfarin experienced longer time to surgery and higher incidence of overall transfusion and postoperative complications within 90 days of surgery. However, warfarin use and day of surgery INR was not independently associated with transfusions or complications. The reason for poorer outcomes in warfarin patients remains a topic of further investigation. LEVEL OF EVIDENCE: Therapeutic Level III.

RESUMO

Background: Although 2-stage exchange arthroplasty, consisting of temporary insertion of an antibiotic-impregnated cement spacer (AICS), is considered the standard of care for chronic periprosthetic joint infection (PJI) in total hip arthroplasty (THA), a consensus on the AICS design has not yet been established. Ceramic-on-polyethylene AICSs (Poly-AICS) are theorized to cause less pain and better function than cement-on-bone AICS (CemB-AICS) but use non-antibiotic-impregnated components that may harbor bacteria. This study evaluates the impact of spacer design on infection-free survivorship following THA reimplantation as well as pain and function during the interim AICS stage. Methods: A retrospective review was performed of all cases of THA PJI treated with either Poly-AICS or CemB-AICS at a single high-volume academic center. Data were collected until the final follow-up after THA reimplantation with an average follow-up duration of 2.6 years. The primary outcome was infection-free survivorship after the final reimplantation. Secondary outcomes included postoperative pain scores, opioid use, time to ambulation, length of stay, complications, and discharge disposition. Results: A total of 99 cases (67 CemB-AICS; 32 Poly-AICS) were included. There were no baseline differences between the 2 groups. There were no differences in infection-free survivorship after reimplantation in survivorship curve comparisons (P = .122) and no differences in postoperative inpatient pain scores, opioid use, length of stay, time to ambulation, complications, or discharge disposition during the AICS stage. Conclusions: Patients with THA PJI treated with Poly-AICS did not have worse infection-related outcomes despite the use of non-antibiotic-impregnated components but also did not appear to have less pain or improved function during the early AICS stage.

RESUMO

Chronic plantar fasciitis is a common cause of foot pain, with conservative treatment providing relief for most patients. However, because of the common occurrence of this pathology, this leaves many patients dissatisfied. The purpose of the present study was to determine the effectiveness of extracorporeal shock wave therapy (ESWT) to treat chronic plantar fasciitis (PF) in a largely active duty population. A review of 82 patients (115 heels) who had undergone ESWT for chronic PF was performed. Outcome data were obtained by patient telephone interviews. All ESWT was conducted at 24 kV for 2000 shocks. Of the 82 patients (115 heels), 76 (93%; 111 heels) agreed to participate. Their mean age was 42 ± 10 years, with 41 males (54%) and 35 females (46%). The mean follow-up period was 42 ± 22 months. Of the patients, 73.6% were active duty military personnel. The mean preoperative pain score of 7.8 ± 2 had improved to 2.5 ± 2 at the last follow-up visit (p <.0001). Active duty patients reported a mean improvement in pain of 4.8 ± 3 compared with 6.8 ± 3 in non-active duty patients (p = .005). Of the 76 patients, 75 (98%) underwent 1 ESWT session, and 1 (2%) requiring 2 sessions. Overall, 74% of patients rated the outcome of their procedure as either good or excellent, with 87% stating that ESWT was successful. Ten patients (18%) left the military because of continued foot pain, with 76% able to return to running. For patients with chronic PF, these results support the use of ESWT to relieve pain in >85% of patients, with a preponderance for better pain relief in patients who are not active duty military personnel.
