Meta-Analysis
PURPOSE
There is currently no consensus on nonoperative management in adult patients after a stable type B ankle fracture. The aim of this review is to compare a removable orthosis versus a cast regarding safety and functional outcome in the NOM of stable type B ankle fractures.
METHODS
A systematic review and meta-analysis were performed using randomized clinical trials and observational studies. The methodological quality of the included studies was assessed with the methodological index for non-randomized studies instrument. Nonoperative management was compared using the number of complications and functional outcome measured using the Olerud and Molander Score (OMAS) or the American Academy of Orthopaedic Surgeons Ankle Score.
RESULTS
Five studies were included. Two were randomized clinical trials, and three were observational studies, including a total of 516 patients. A meta-analysis showed statistically significant higher odds of developing complications in the cast group [odds ratio (OR), 4.67 (95% confidence interval (CI) 1.52-14.35)]. Functional outcome in OMAS did not vary significantly at 6 weeks, mean difference (MD) - 6.64 (95% CI - 13.72 to + 0.45), and at 12 weeks, MD - 6.91 (95% CI - 18.73 to + 4.91). The mean difference of functional outcome in OMAS at 26 weeks or longer was significantly better in the removable orthosis group; MD - 2.63 (95% CI - 5.01 to - 0.25).
CONCLUSION
Results of this systematic review and meta-analysis show that a removable orthosis is a safe alternative type of NOM, as complication numbers are significantly lower in the orthosis group. In addition, no statistically significant differences were found in terms of functional outcome between a removable orthosis and a cast at 6 and 12 weeks. The 6-week and the 26-week OMAS results show that in patients with stable type B ankle fractures, a removable orthosis is non-inferior to a cast in terms of functional outcome.

Meta-Analysis
INTRODUCTION
Tension band wiring (TBW) and screw fixation (SF) are common surgical treatments for medial malleolar fractures (MMFs); however, no systematic review has identified which fixation method is superior. This study aimed to determine the most optimal MMF fixation method by comparing the clinical and radiological outcomes of TBW and SF through a systematic review and meta-analysis of the literature.
HYPOTHESIS
We hypothesized that there may be differences in outcomes between TBW and SF for treating MMFs.
METHODS
MEDLINE, Embase, and the Cochrane Library were systematically searched for studies that compared TBW and SF for MMF treatment published through June 8, 2021. Fracture union, outcome scores, and postoperative complications were analyzed.
RESULTS
We included 10 studies with 512 MMF cases; 218 and 294 patients were treated with TBW and SF, respectively. Pooled analysis revealed no significant differences between them for all outcome variables, including the time to fracture union (mean difference=-0.59 weeks; 95% confidence interval [CI], -1.82 to 0.64; p=0.35; I=70%), number of excellent or good outcomes based on the final Olerud and Molander Ankle score (odds ratio [OR], 1.46; 95% CI, 0.53-5.02; p=0.47; I=0%), delayed union rate (OR, 0.94; 95% CI, 0.34-2.59; p=0.91; I=17%), superficial infection rate (OR, 1.19; 95% CI, 0.33-4.26; p=0.79; I=0%), and number of fixation failures (OR, 0.53; 95% CI, 0.16-1.74; p=0.29; I=13%).
CONCLUSIONS
Both TBW and SF are excellent clinical and radiological methods for MMF fixation. However, an appropriate fixation method should be chosen according to the fracture type and size and bone quality considering the advantages and disadvantages of each method.

INTRODUCTION
The literature largely addresses questions of diagnostic accuracy and therapeutic accuracy. However, the magnitude of the clinical impact of syndesmosis injury is commonly described in intuitive yet qualitative terms. This systematic review aimed to quantify the impact of syndesmosis injury.
METHODS
Published clinical outcomes data were used to compute an effect size reflecting the impact of syndesmosis injury. This was done within the clinical contexts of isolated syndesmosis injury and syndesmosis injury with concomitant ankle fracture. Clinical outcomes data included Olerud-Molander (OM) and American Orthopaedic Foot and Ankle Society (AOFAS) scores, visual analog scale for pain, and days missed from sport competition. Parametric data were compared with Student t tests. Effect size was computed using Cohen's d.
RESULTS
In ankle fracture patients, syndesmosis injury demonstrated a large effect size for OM (d = 0.96) and AOFAS (d = 0.83) scores. In athletic populations without concomitant ankle fracture, syndesmosis injury demonstrated a large effect size on days missed from competition (d = 2.32).
DISCUSSION
These findings confirm the magnitude of the negative impact of syndesmosis injury in athletic populations with isolated injury and in ankle fracture patients. In ankle fracture patients, this large negative effect remains despite surgery. Thus, syndesmosis repair may not fully mitigate the impact of the injury.
