1 · What the graph read from it

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.

2 · The registry

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

purposePhalangeal Akin osteotomy of the greater toe is a frequently used surgical procedure for correcting hallux valgus interphalangeus deformity. However, previous research did not investigate percutaneous techniques of the Akin osteotomy. It was the aim of this study to investigate feasibility, corrective potential, and safety of a percutaneous minimally invasive Akin osteotomy.

methodsWe present a series of 81 feet, in which a percutaneous Akin technique was performed using a high-speed burr but no fixation device. The most important outcome parameters were determined as the proximal to distal phalangeal articular angle (PDPAA) (corrective effect of the osteotomy), the osteotomy healing (full, partly, no visibility of the osteotomy gap), and the integrity of the lateral cortical hinge.

resultsWith regard to the main hypothesis we found significant changes in the PDPAA over the whole period of time (p < 0.001). Post-hoc tests determined that the PDPAA changed from 10° pre-operatively (Md, IQR 4.3) to 2.3° post-operatively (Md, IQR 3.7) (p < 0.001). Post-operatively no significant changes in PDPAA were found within the first six weeks and from six weeks to three months (no loss of correction). Osteotomy healing was satisfactory as well. Three months post-operatively, there were no patients with a fully visible osteotomy gap, 28.3% with a partly visible osteotomy gap, and 71.7% had no visible gap. Interestingly, we could not observe a statistically significant correlation between bone healing and the integrity of the lateral cortical hinge.

conclusionFrom our findings we conclude that the minimally invasive Akin osteotomy without osseous fixation provides effective deformity correction without significant loss of correction thereafter. This procedure appears to be safe with regard to osseous healing. Surprisingly, the healing process of the osteotomy showed no dependence on the integrity of the lateral cortical hinge. LEVELS OF EVIDENCE: Therapeutic, Level IV, retrospective case series.
