Safety and Efficacy of Prophylactic Closed Incision Negative Pressure Therapy after Acute Fracture Surgery

Is Staged Surgery Always Necessary for Schatzker Type IV-VI Tibial Plateau Fractures? A Comparison Study

AIMS

This study aims to compare the outcomes of immediate (followed by closed-incision negative-pressure therapy use) versus delayed ORIF in patients with Schatzker type IV-VI TPFs.

PATIENTS AND METHODS

A prospective study of patients undergoing ORIF between January 2018 and December 2019 was performed. The inclusion criteria were patients (>18 years) with a closed fracture sent to the emergency room (ER) within 24 h of injury. All the patients underwent preoperative image evaluation. Two senior orthopedic trauma surgeons evaluated the soft tissue condition in the ER by 5P's of the compartment syndrome, judging the timing of the operation of definitive ORIF. Group 1 (n = 16) received delayed ORIF. Group 2 (n = 16) received immediate ORIF and ciNPT use. Patient follow-up occurred after 2 and 6 weeks and 3, 6, and 12 months after surgery. The assessments included the time to definitive fixation, the length of hospital stay, the time to bone union, surgical site complications, and reoperation within 12 months. A universal goniometer was used to measure the postoperative 3 m, 6 m, and 12 m ROM.

RESULTS

The patient demographics were similar between the groups (p > 0.05). Group 2 displayed significantly a shorter time to definitive fixation (5.94 ± 2.02 vs. 0.61 ± 0.28, p < 0.0001) and hospital stay (14.90 ± 8/78 vs. 10.30 ± 6.78, p = 0.0016). No significant difference was observed in the time to bone union, surgical site complication incidence, and reoperation rates (p > 0.05). Flexion and flexion-extension knee ROM were demonstrated to be significantly improved in Group 2, 3, 6, and 12 months postoperatively (p < 0.0001).

CONCLUSIONS

In this study, early ORIF and ciNPT use resulted in a shorter hospital length of stay, a reduced time to early active motion of the knee, and improved knee ROM. These results suggest that early ORIF with ciNPT for Schatzker type IV-VI TPFs is safe and effective in some patients. However, further research to confirm these findings across larger and more diverse populations is needed.

Immediate application of negative pressure wound therapy following lower extremity flap reconstruction in sixteen patients

Negative pressure wound therapy (NPWT) is usually applied in wound management and soft-tissue salvage after the development of complications. However, immediate postoperative application of NPWT over the flap coverage is seldom reported. We evaluate the effectiveness of immediate postoperative application of NPWT following fasciocutaneous or muscle flap coverage for lower leg reconstruction. A retrospective review of patients who underwent either fasciocutaneous or muscle flap coverage of lower leg soft-tissue defects applied with NPWT immediately after surgery was conducted in a level I trauma center. Sixteen patients, with an average age of 51.2 years, were included in the study. Nine patients had trauma-related soft-tissue loss, six had subsequent soft-tissue defects after debridement, and one had burn injury. Two patients had been treated with free anterolateral thigh flaps, 11 with pedicle flaps, and three with muscle flaps. All flaps survived except for those in two patients with venous congestion on postoperative day 1, which needed further debridement and skin grafting. Therefore, the use of immediate incisional NPWT is an alternative for wound care following flap coverage. The U-shaped design allows easy flap observation and temperature check. Furthermore, this method eliminates any concerns of vascular pedicle compression under negative pressure.
