Unplanned Return to the Operating Room in Upper-Extremity Surgery: Incidence and Reason for Return.

PURPOSE

Complications after upper-extremity surgery are generally infrequent. The purpose of this study was to assess the rate of early unplanned return to the operating room (URTO) within 3 months after surgery) in upper-extremity surgical procedures. Our hypotheses were that the rate of URTO in upper-extremity surgery would be low and that surgically treated fractures would be at greatest risk for complications.

METHODS

We performed a retrospective review of all upper-extremity surgical procedures performed at a large academic practice of fellowship-trained hand surgeons over a 5-year period. A chart review was conducted of all patients who underwent a second surgery within 3 months of the initial surgery. The surgical billing database was queried to determine the incidence of URTO per Current Procedural Terminology code.

RESULTS

There were 422 Current Procedural Terminology codes with URTO out of a total of 62,608, for an incidence of 0.6%. The most frequently performed procedures were carpal tunnel release (10,674; 0.1% URTO), trigger finger release (4,549; 0.5% URTO), and open reduction internal fixation (ORIF) for distal radius fracture (2,728; 1.2% URTO). Procedures with the highest incidences of URTO were open reduction and internal fixation of the ulna (4.9%) and excision of the olecranon bursa (4.1%). Traumatic injuries were more commonly associated with URTO compared with elective procedures. Bony trauma and soft tissue trauma had URTO incidences of 1.4% and 1.1%, respectively, whereas bony elective and soft tissue elective cases were 0.6% and 0.4%, respectively.

CONCLUSIONS

The 90-day URTO rate after upper-extremity surgery was low but higher than previously reported 30-day reoperation rates. Elbow procedures were most likely to result in URTO, as were procedures relating to bony and soft tissue trauma. Based on these results, we are able to counsel patients that the most common procedures we perform have low URTO rates, but surgically treated fractures are at greatest risk.

TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.
