Risk factors for 30-day postoperative complications and mortality following open reduction internal fixation of distal radius fractures.

PURPOSE: To identify the incidence and risk factors for 30-day postoperative morbidity and mortality following operative treatment of distal radius fractures in a multicenter cohort. METHODS: We retrospectively queried the American College of Surgeons National Surgical Quality Improvement Program database for the years 2005-2011 for cases of closed distal radius fractures treated operatively with internal fixation. Patient demographics, comorbidities, and operative characteristics were analyzed. Thirty-day postoperative complications were identified and separated into categories of major morbidity or mortality, minor morbidity, and any complication. Risk factors were identified using univariate and multivariate analyses. RESULTS: We identified 1,673 cases of closed distal radius fractures managed with internal fixation. The overall incidence of having any early complication was 3%. Major morbidity was 2.1%, which included 4 patient deaths, and minor morbidity was 1%. The most common major morbidity was a return to the operating room (16 patients). The most common minor morbidity was urinary tract infection (6 patients). The multivariate analysis demonstrated ASA class III or IV, dependent functional status, hypertension, and myocardial infarction/congestive heart failure to be significant risk factors for any early complication. There was a 10.0% complication rate in the inpatient group and a 1.3% complication rate in the outpatient group. CONCLUSIONS: The incidence of early complications following internal fixation for closed distal radius fractures was low, especially in the outpatient group. In the setting of an isolated injury to the distal radius, the data presented here can provide prognostic information for patients during informed consent for what is considered to be an elective procedure. Surgeons should consider risk of morbidity and mortality when considering surgery for patients with noteworthy cardiopulmonary disease, increased ASA class, or poor functional status. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.

Thromboembolism Following Shoulder Arthroscopy: A Retrospective Review.

BACKGROUND: Thromboembolism following shoulder arthroscopy is considered an uncommon complication, with fewer than 50 cases reported in the literature. Arthroscopy of the shoulder is one of the most commonly performed orthopaedic procedures, with low associated risks. PURPOSE: To identify potential risk factors for the development of venous thromboembolism (VTE) following shoulder arthroscopy and to determine the overall incidence of this complication. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: A retrospective case-control review was performed of patients who developed symptomatic deep venous thrombosis (DVT) or pulmonary embolism (PE) following shoulder arthroscopy. Multiple surgeons from across North America were queried. For every case of DVT or PE identified, 2 control cases of shoulder arthroscopy were analyzed. The incidence of DVT/PE following shoulder arthroscopy was determined. A univariate analysis and a multivariate logistic regression model were conducted to identify any potential risk factors for the development of VTE following shoulder arthroscopy. RESULTS: A total of 17 surgeons participated in this study and had performed a total of 15,033 cases of shoulder arthroscopy from September 2002 through August 2011. Eleven of the 17 participating surgeons had had a patient with a VTE complication during this time frame. The incidence of VTE in the 15,033 cases was 0.15%; 22 patients of the 15,033 patients had a DVT (n = 15) and/or PE (n = 8). Forty-four control cases were also analyzed. Univariate and multivariate analyses were performed. No significant risk factors were identified other than patient positioning. All cases and controls were positioned in the beach-chair position for surgery. CONCLUSION: The results of this study show that although rare, VTE occurs following shoulder arthroscopy at a rate of 0.15%. The variables analyzed in the cases of VTE compared with the control cases did not show any significant risk factors. All cases were positioned in the beach-chair position. Further analysis of future cases is warranted.
