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

backgroundThe purpose of this study was to evaluate the rates of implant-related complications and mortality after treatment of an intertrochanteric or subtrochanteric fracture with a short or long Gamma nail.

methodsBetween September 1998 and August 2003, 644 patients at 2 centers treated with a long or short Gamma nail for a hip fracture were prospectively enrolled in this study. These patients were followed until they reached 1 of the study end points, which included death, a reoperation directly related to the Gamma nail, or the end date of the study.

resultsThe average age (and standard deviation) of the patients included in the study was 81.3 ± 8.6 years at the time of the operation, and 28.3% of the patients were male. The rate of implant-related complications was 9.9%. The most common complications included peri-implant fracture (4.2%), proximal lateral thigh discomfort requiring extraction of the implant (2.0%), and lag-screw cutout (1.1%). Interestingly, more than half (56%) of the 27 peri-implant fractures occurred >1.5 years after the index operation. The median time from the operation to death was 2.9 years (range, 0 to 17.1 years). The 30-day mortality rate after treatment was 9.5%. Patients with American Society of Anesthesiologists (ASA) class-3 or 4 physical status had a significantly higher risk of mortality than ASA class-1 patients.

conclusionsGamma nails are effective in the treatment of intertrochanteric and subtrochanteric fractures. However, 9.8% of patients had complications requiring additional surgery. The most common serious complications include peri-implant fracture and lag-screw cutout. Several peri-implant fractures occurred long after the index procedure. Patients had a high rate of mortality (27%) after 1 year, and higher preoperative ASA class was found to be a predictor of increased risk of mortality. Therefore, clinicians must carefully consider patients' preoperative comorbidities when counselling patients on the risks of surgery. LEVEL OF EVIDENCE: Therapeutic Level II.
