RESUMO
BACKGROUND: Cast immobilization is the mainstay of treatment for stable pediatric supracondylar humeral fractures (SCHFs). In recent years, a waterproof and breathable hybrid-mesh (HM) cast has emerged and been marketed to address common complaints such as itch, skin irritation, and malodor. Hence, this randomized controlled trial seeks to assess the overall satisfaction, comfort, and clinical outcomes of using HM casts in the conservative treatment of stable pediatric SCHF. METHODS: Seventy-nine patients (age range: 1 to 10 y) with modified Gartland's classification Type I and Type IIa SCHF were recruited and randomized for immobilization with either fiberglass or HM long-arm cast for 3 weeks. During follow-up visits, patients were assessed for any loss of reduction and skin rash. The weight of casts, the presence of cast breakage, the duration of cast application, and removal were recorded. A self-reported patient comfort and satisfaction questionnaire was also administered during the same visit. RESULTS: The final analysis included 38 patients immobilized with fiberglass casts and 39 patients with HM casts. Despite the significantly longer duration required for HM cast removal (4.18±1.25 min vs. 2.25±0.55 min, P <0.001), the HM cast was significantly lighter than its fiberglass counterpart (162.82±23.94 g vs. 203.95±36.52 g, P <0.001). The HM casts have better comfort (4.05±0.887 vs. 3.47±0.951, P =0.007) and satisfaction (3.69±1.055 vs. 3.11±0.953, P =0.012) scores as compared to fiberglass casts for immobilizing pediatric SCHF without compromising clinical outcome. CONCLUSIONS: HM casts have better comfort and overall satisfaction as compared to conventional fiberglass casts for immobilizing pediatric SCHF without compromising clinical outcomes. LEVEL OF EVIDENCE: Level II-therapeutic studies-investigating the results of treatment.

Our study aimed to compare the clinical and radiographic outcomes of transitional distal tibia fractures treated with K-wire fixation versus screw fixation after open reduction. A retrospective study was performed on all displaced transitional distal tibia fractures that underwent operative fixation. Following open reduction, surgical fixation was performed using either percutaneously inserted 2.0 mm K-wires, or 4.0 mm partially-threaded cannulated cancellous screws. Clinical and radiographic outcomes between the two groups were assessed using the modified Weber score. Other outcome measures assessed were surgical time, casting duration, follow-up duration and duration before return-to-sports. We recruited 49 patients with transitional distal tibia fractures requiring open reduction and surgical fixation. There were 18 patients in the K-wiring group (KWG), and 31 patients in the screw fixation group (SFG). All patients in both groups had excellent clinical and radiographic outcome based on the modified Weber's scoring, full radiological healing, and no residual displacement upon final follow up. The KWG had significantly shorter surgical time (41.0 min versus 75.1 min, P < 0.0001) and shorter follow-up duration needed before discharge (5.4 months versus 8.7 months, P = 0.024). However, they required a longer post-operative casting duration (7.3 weeks versus 5.3 weeks, P = 0.006). No significant difference was found for the duration before return to sports between both groups. Complications were few in this study group. Superficial pin site infection was noted in one patient in the KWG, and valgus deformity of the ankle was noted in one patient in the SFG. In our study, surgical treatment of transitional distal tibia fractures demonstrated equally excellent outcomes when treated by open reduction with either K-wire or cannulated screw fixation. Level of evidence: III.
