Grice extra-articular subtalar fusion for spastic pes planovalgus.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionA pes planovalgus deformity, an unstable foot deformity, affects the gait of children with cerebral palsy (CP). Treatments, including subtalar fusion, were proposed. The Grice procedure maintains foot stability, but bone graft non-union poses a challenge. This study aimed to identify the rate and factors related to post-operative bone graft non-union.
methodsThirty-one paediatric CP patients (age, 8.9 ± 1.8 years) who underwent the Grice procedure (53 feet) using ipsilateral tibial bone grafts were reviewed. Pre-operative gross motor function classification system (GMFCS) classes were class 1 in five, 2 in five, 3 in 14, and 4 in seven patients. Standing foot radiographs were assessed for signs of non-union, and parameters (talocalcaneal and talar declination angles and talar head uncovering index) measured pre-operatively, post-operatively, and at the most recent evaluation were compared. Factors associated with bone graft non-union were analysed by regression analysis. P < 0.05 was considered statistically significant. Degenerative changes in hindfoot joints were evaluated by Bargon's criteria.
resultsAt the average follow-up evaluation at 5.4 ± 4.3 years, the GMFCS class was improved or was maintained in 29/31 patients. Post-operative radiographic measurements were restored and were maintained over the follow-up period (P < 0.001). A total of 14/53 feet (26%) had non-union. The pre-operative lateral talocalcaneal angle (OR 1.08, p = 0.04) and follow-up duration (OR 1.18, p = 0.03) were identified in univariate analysis as potential factors related to non-union but were not confirmed in a multivariate model. Hindfoot joints in most feet showed mild degenerative changes.
conclusionGrice subtalar fusion in patients with a higher pre-operative lateral talocalcaneal angle might lead to bone graft non-union.
