Insights
A new foam and fiberglass casting technique for pediatric supracondylar humerus fractures effectively manages swelling and fracture reduction, showing comparable results to traditional casts without increasing complication risks.
Area of Science:
- Orthopedic surgery
- Pediatric trauma care
- Biomedical engineering
Background:
- Pediatric supracondylar humerus fractures require careful postoperative casting to manage swelling and prevent compartment syndrome.
- Traditional casting methods may not optimally accommodate post-operative edema.
- Minimizing risks like compartment syndrome is crucial in pediatric fracture management.
Purpose of the Study:
- To introduce and evaluate a novel casting technique using foam and fiberglass for pediatric supracondylar humerus fractures.
- To compare the efficacy and safety of this new method against traditional casting.
- To assess the impact on fracture reduction, swelling management, and complication rates.
Main Methods:
- Retrospective chart review of 541 pediatric patients (0-14 years) treated for supracondylar humerus fractures.
- Comparison of a new casting method (sterile foam with circumferential fiberglass) versus traditional casts.
- Analysis of fracture types, preoperative neurovascular status, and postoperative outcomes including compartment syndrome and reoperation.
Main Results:
- The novel foam casting technique was used in 35% of patients, particularly for Gartland type 3 fractures and those with preoperative neurovascular deficits.
- No compartment syndrome was observed in any patient in either casting group.
- Reoperation rates were not significantly associated with cast splitting or the use of foam.
Conclusions:
- A new casting method involving direct skin application of foam followed by circumferential fiberglass provides effective immobilization for pediatric supracondylar humerus fractures.
- This technique offers the strength of a circumferential cast while allowing for post-operative swelling.
- Results suggest comparable outcomes to traditional casts, potentially reducing the need for cast splitting, especially in severe fractures.
Background:
Varying casting techniques are used after surgical treatment of pediatric supracondylar humerus fractures. The goals are to maintain fracture reduction, while accommodating soft tissue swelling and minimizing the risk of compartment syndrome.
Methods:
A retrospective chart review of consecutive patients aged 0 to 14 years who underwent surgical treatment of supracondylar humerus fractures over a 9½-year period at a pediatric trauma center was performed. A new method of casting, in which one half inch sterile foam is applied directly to the skin and overwrapped by circumferential fiberglass, is presented and compared with traditional casts.
Results:
A total of 541 consecutive patients were included. Foam had been used in 35% (190/541) of patients. Foam was used significantly more frequently in Gartland type 3 fractures (133/314 patients, 42%) than in type 2 fractures (57/227 patients, 25%) (P<0.001). Foam was also used more often in patients with preoperative neurovascular deficits (34/57, 60%) than in those without (156/484, 32%) (P<0.001). No patient in either group developed compartment syndrome postoperatively. Both patients in the study who required revision closed reduction and pinning were casted without foam, and one of these casts had been split. Reoperation was not associated with cast splitting (P=0.216) or foam use (P=0.543).
Conclusions:
For postoperative immobilization of supracondylar humerus fractures we present a new method of placing foam directly on the skin, followed by circumferential fiberglass casting. This method offers the theoretical advantage of the strength of a circumferential cast, plus the benefit of allowing for swelling. Although the novel foam and cast combination was used in more severe fractures, results were comparable to traditional casts and may reduce the need for cast splitting.

Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
