[Complications after dynamic in-situ fixation of the femoral head in patients with slipped capital femoral epiphysis].

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
backgroundSlipped capital femoral epiphysis (SCFE) requires surgical treatment. In German-speaking countries, dynamic in-situ fixation is commonly used for mild SCFE lenta. Various implants are available for this purpose.
objectiveHigh complication rates have been reported for the removal of titanium gliding screws. In this retrospective study, we analyzed the complications in the treatment of SCFE, particularly focusing on the removal of sliding screws made of stainless steel and K‑wires. MATERIALS AND
methodsA total of 111 patients with SCFE were treated, including 96 fixations using stainless steel sliding screws, 93 wire pinning procedures, and 69 hips treated with a combination of both techniques. Additionally, 43 Imhäuser osteotomies were performed. Complications arising from these treatments were analyzed.
resultsIn 14 patients, 23 complications were observed. Avascular necrosis of the femoral head occurred in three cases. Two patients sustained a fracture of the proximal femur. One patient presented with soft tissue irritation following fixation with both sliding screws and K‑wires. Infections occurred in three patients. Due to implant misplacement or breakage, 6 patients required a total of 12 revision surgeries. Two patients developed postoperative hematomas, which were surgically evacuated. No complications were observed related to implant removal. DISCUSSION: The issues described in the literature regarding the removal of titanium screws were not observed with stainless steel screws. This difference can be attributed to material properties: titanium screws have lower torsional strength and require higher torque for removal.
