Key Takeaway
Consider short leg casting as an alternative to long leg casting for pediatric tibial fractures, but interpret findings cautiously.
This systematic review and meta-analysis compared short leg casting (SLC) with long leg casting (LLC) in pediatric patients with tibial fractures, pooling data from 413 patients. The primary outcome was stable healing and functional recovery, with secondary outcomes including angulation, cast duration, complications, and time to weight-bearing and union.
For coronal angulation, the mean difference was 0.12 degrees (95% CI -0.89 to 1.12, I2 = 58%), and for sagittal angulation, 0.18 degrees (95% CI -0.71 to 1.07, I2 = 56%), indicating no significant difference between groups. Cast duration was similar (MD -0.74 weeks, 95% CI -1.49 to 0.01, I2 = 92%), and complication rates showed no difference (OR 0.76, 95% CI 0.25 to 2.34, I2 = 0%).
However, SLC was associated with a shorter time to weight-bearing (MD -2.29, 95% CI -4.49 to -0.08, I2 = 68%) and faster time to union (MD -1.21, 95% CI -2.16 to -0.25, I2 = 30%). These findings suggest a potential functional advantage for SLC.
The authors note limitations including retrospective design, clinical heterogeneity, and risk of confounding. The level of evidence is III, and causality cannot be inferred. Adverse events were not reported.
In practice, SLC may be considered as an alternative to LLC for pediatric tibial shaft and distal tibial physeal fractures, but clinicians should weigh the potential benefits against the limitations of the available evidence.
A review of data from 413 pediatric patients with tibia fractures compared two types of casts: short leg casting (SLC) and long leg casting (LLC). The study looked at how these different casting methods affected the healing process, the angle of the bone, and the time it took for children to move around.
Researchers found that children using short leg casts were able to begin weight-bearing on their legs faster than those in long leg casts. Additionally, the results showed that bone union happened more quickly with the short leg casting method. Other factors, such as the angle of the bone and the overall duration of the cast, were similar between both groups. No differences were found in complication rates between the two methods.
Because this review relied on retrospective data, the results should be viewed with caution. The evidence is limited by differences in how patients were treated across different clinics. While short leg casts may be a helpful alternative for certain types of fractures, you should talk to a doctor to determine the best treatment for a specific child.
What this means for you:
Short leg casts may allow children with tibia fractures to bear weight and heal faster than long leg casts.
Common questions
How does a short leg cast differ from a long leg cast for children?
A short leg cast (SLC) covers less of the leg than a long leg cast (LLC). In this study of 413 children, both methods resulted in similar bone angles and complication rates. However, children with short leg casts were able to begin weight-bearing and achieve bone union faster than those in long leg casts.
Is a short leg cast safer for a child's broken leg?
The study found no difference in complication rates between short leg casting and long leg casting. Because the evidence comes from a retrospective study with some inconsistencies, it does not prove that one method is safer than the other. You should consult a medical professional to determine the safest option for a specific injury.
Does a short leg cast help the bone heal faster?
The data showed that children using short leg casts had a faster time to union compared to those in long leg casts. Specifically, the study found a mean difference of -1.21 weeks for time to union in favor of short leg casting. This suggests it may be a viable alternative for certain types of tibial fractures.
BACKGROUND: Pediatric tibial fractures are common long-bone injuries, yet uncertainty remains in the optimal immobilization strategy. The comparative effectiveness and safety of short leg versus long leg casts in achieving stable healing and functional recovery have not been clearly established.
METHODS: A literature search was conducted across Medline, CINAHL, Embase, and Cochrane Library, from inception to August 2025, following PRISMA guidelines and registered with the International Prospective Register of Systematic Reviews (PROSPERO). Statistical analyses were performed using a random-effects model.
RESULTS: The initial search yielded 1236 studies; 6 studies with 413 pediatric patients met the inclusion criteria. A total of 163 underwent short leg casting (SLC) and 250 long leg casting (LLC). No differences were observed between SLC and LLC for coronal angulation (MD=0.12 degrees, 95% CI=-0.89 to 1.12, I2 =58%) or sagittal angulation (MD=0.18 degrees, 95% CI=-0.71 to 1.07, I2 =56%). Subgroup analyses showed no differences for tibial shaft fractures or Salter-Harris distal tibial fractures. Cast duration was similar between groups (MD=-0.74 wk, 95% CI=-1.49 to 0.01, I2 =92%). Overall complication rates did not differ (OR=0.76, 95% CI=0.25 to 2.34, I2 =0%), with no differences in Salter-Harris subgroup analysis (OR=0.67, 95% CI=0.05 to 9.91; I2 =54%). SLC was associated with shorter time to weight-bearing (MD=-2.29, 95% CI=-4.49 to -0.08, I2 =68%) and faster time to union (MD=-1.21, 95% CI=-2.16 to -0.25, I2 =30%).
CONCLUSION: SLCs may be considered as an alternative to LLCs in pediatric tibial shaft and distal tibial physeal fractures based on currently available retrospective comparative evidence. However, the evidence is limited by the retrospective design, clinical heterogeneity, and risk of confounding. Further prospective comparative studies are needed to define optimal indications for SLC use in this population.
LEVEL OF EVIDENCE: Level III, systematic review and meta-analysis of retrospective comparative studies.
