Neck modularity in total hip arthroplasty: a retrospective study of nine hundred twenty-eight titanium neck implants with a maximum follow-up of eighteen years.

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
purposeNeck modularity was introduced to improve total hip arthroplasty (THA) accuracy, but it has been associated with early breakages and corrosion issues. In our hospital, modular necks have been in clinical use since the 1990s. We retrospectively analysed the occurrence of these sequelae in implants placed between January 2000 and December 2014.
methodsSurvival data from patients operated on in our hospital were obtained from the regional arthroplasty registry (Registro dell'Impiantologia Protesica Ortopedica, RIPO). The cohort comprised 928 THAs on 908 patients. The average patient age was 67.8 years. Main indications were primary osteoarthritis (71.4%), fracture (9.2%), congenital dysplasia or congenital luxation (7.8%), and idiopathic osteonecrosis (6.4%). All femoral stems were cementless, with 318 anatomically shaped (34.3%), 579 straight (62.4%), and 31 short stems (3.3%). All necks used were made of titanium alloy. The average follow-up time was 9.6 years (range, 4-18 years).
resultsIn total, 66 revisions were reported. The main revision causes were periprosthetic fractures (33.3%), aseptic stem loosening (19.7%), luxation (18.2%), and implant breakage (12.1%). Five modular neck breakages were recorded. The overall survival rate was 87.7% at 17 years. We did not observe any component corrosion. The neck breakage rate was 0.5%, and the luxation rate was 1.3%.
conclusionsOur experience suggests that neck modularity is a safe, effective way to reconstruct the proximal femur in THA patients. We attribute the absence of corrosion to the exclusive use of titanium necks.
