Trabecular metal screw implanted for avascular necrosis of the femoral head may complicate subsequent arthroplasty surgery.
Article in European journal of orthopaedic surgery & traumatology : orthopedie traumatologie, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
A trabecular metal screw has been suggested to treat avascular osteonecrosis of the femoral head. Non-surgical management with partial weight bearing can only be selected for early stages and very small lesions. Even in such cases, it has been proven to be ineffective in 80-90 % of patients. Conversely, the results with trabecular metal implants are not always clinically satisfactory, and some patients can show emerging pain and activity limitations that could require conversion to a total hip arthroplasty. Hereby we report the results of 6 patients who underwent this implant and describe the histopathology of the bone at the femoral neck and to speculate on the causes of complications encountered during arthroplasty surgery. The necrosis was stopped in 1 case, and 5 hips showed disease progression. Two protrusions of the screw apex were observed. In one case, rupture of the greater trochanter during prosthesis implant occurred. After trabecular metal implants for avascular osteonecrosis, some patients can require conversion to a total hip arthroplasty. Two patients had an intraoperative fracture with detachment of the greater trochanter that required wiring. Complications related to implant removal can be encountered, and the orthopedic surgeon should be aware of removal techniques.
