Hold the Antibiotics: Are Preoperative Antibiotics Unnecessary in the Treatment of Pediatric Supracondylar Humerus Fractures?

BACKGROUND: Supracondylar humerus (SCH) fracture is the most common elbow injury in children and often treated with closed reduction and percutaneous pinning (CRPP). There is little published evidence supporting or refuting the use of perioperative prophylactic antibiotics for SCH CRPP in the pediatric population. The purpose of this study is to evaluate the rate of surgical site infection for patients with and without preoperative antibiotics. METHODS: A retrospective chart review was conducted of patients less than or equal to 16 years from 2012 to 2018 who underwent primary CRPP. Open fractures, multilimbed polytraumas, and immunodeficient patients were excluded. Infection rates were compared using a noninferiority test assuming a 3% infection rate and a predefined noninferiority margin of 4%. A total of 255 patients were needed to adequately power the study. RESULTS: Of the 1253 cases identified, 845 met eligibility criteria. A total of 337 received antibiotics, and 508 did not. Preoperative nerve injury (P=0.0244) and sterilization technique (P<0.0001) were associated with antibiotic use: 4 patients developed an infection; there were successfully treated superficial infections, and 1 was a deep infection requiring a formal debridement. There were 8 patients that had a recorded mal-union, and 6 patients required additional procedures; 1 patient had a postoperative compartment syndrome on postoperation day 1. The infection rates among patients treated with and without antibiotics were 0.60% and 0.40%, respectively. The absence of antibiotics was not clinically inferior to using antibiotics (P=0.003). CONCLUSIONS: Infection remains a rare complication following CRPP of SCH fractures. According to our current data, not giving perioperative antibiotics was not inferior to using perioperative antibiotics for preventing superficial or deep infection in patients undergoing CRPP of SCH fractures. With the increase in attention to antibiotic stewardship, it is important to eliminate unnecessary antibiotic use while continuing to maintain a low rate of surgical site infection. LEVEL OF EVIDENCE: Level IV-case series. This is a therapeutic study that investigates the results from a case series.

Effect of NSAID Use on Bone Healing in Pediatric Fractures: A Preliminary, Prospective, Randomized, Blinded Study.

BACKGROUND: This study aimed to investigate if nonsteroidal anti-inflammatory drugs (NSAIDs) used in the acute phase of bone healing in children with fractures result in delayed union or nonunion as compared with patients who do not take NSAIDs for pain control during this same time period. METHODS: In this prospective, randomized, parallel, single-blinded study, skeletally immature patients with long bone fractures were randomized to 1 of 2 groups for their postfracture pain management. The NSAID group was prescribed weight-based ibuprofen, whereas the control group was not allowed any NSAID medication and instead prescribed weight-based acetaminophen. Both groups were allowed to use oxycodone for breakthrough pain. The primary outcome was fracture healing assessed at 2, 6, and 10 weeks. RESULTS: One-hundred-two patients were enrolled between February 6, 2014 and September 23, 2016. Ninety-five patients (with 97 fractures) completed a 6-month follow-up (46 patients with 47 fractures in the control group and 49 patients 50 fractures in the NSAID group). None achieved healing at 1 to 2 weeks. By 6 weeks, 37 of 45 patients (82%) of control group and 46 out of 50 patients (92%) of ibuprofen group had healed fractures (P=0.22). At 10 to 12 week follow-up, 46 (98%) of the control group fractures were healed and 50 (100%) of the ibuprofen group fractures were healed. All were healed by 6 months. Healing was documented at a mean of 40 days in the control group and 31 days in the ibuprofen group (P=0.76). The mean number of days breakthrough oxycodone was used was 2.4 days in the control group and 1.9 days in the NSAID group (P=0.48). CONCLUSION: Ibuprofen is an effective medication for fracture pain in children and its use does not impair clinical or radiographic long bone fracture healing in skeletally immature patients. LEVEL OF EVIDENCE: Level I-therapeutic.
