Evaluation of patient outcomes after operative treatment of intra-articular calcaneus fractures

Background: Percutaneous reduction with fixation and open reduction internal fixation are often used to treat intra-articular calcaneus fractures with no consensus on the preferred method. Open techniques have been associated with an increased risk of wound complications, while percutaneous techniques may result in inferior reduction capabilities. These injuries pose a challenge to patients as they often result in poor patient outcomes. We retrospectively analyzed patient outcomes of a single surgeon's experience in treating these injuries at a busy urban Level 1 trauma center. Methods: Patients with intra-articular calcaneus fractures managed operatively over 10 years with a minimum six-month follow-up were included. Patients were divided into two cohorts based on operative technique: closed reduction and percutaneous fixation (CRPF) or open reduction internal fixation (ORIF). Descriptive analysis of each cohort included postoperative infection, the need for repeat operations, development of post-traumatic subtalar arthritis, and reduction capabilities as assessed by Bohler's angle. Results: Sixty-two patients were included in this study, with 33 patients in the CRPF group and 29 patients in the ORIF group. Infection requiring a return to the operating room occurred in 1 (3%) CRPF and 7 (24%) ORIF patients. Instrumentation was removed in 23 (70%) CRPF and 9 (31%) ORIF patients. Clinical subtalar arthritis developed in 10 (30%) CRPF and 7 (24%) ORIF patients, requiring arthrodesis in 2 (6%) and 5 (17%) patients, respectively. Both techniques had acceptable restoration of Bohler's angle immediately postoperatively and at final follow-up. Conclusions: Percutaneous reduction with fixation and open reduction internal fixation may both be considered for the surgical treatment of intra-articular calcaneal fractures. Indications for each technique may vary between surgeons, and each has its own set of risk factors and complications, however, both have been shown to result in an acceptable reduction.
