Femoral head fracture management: outcomes of surgical hip dislocation with bioabsorbable screw fixation.

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
purposePipkin fractures are rare, complex hip injuries typically caused by high-energy trauma. Surgical management must balance adequate exposure with preservation of femoral head vascularity. We evaluated outcomes of surgical hip dislocation with absorbable screw fixation for Pipkin fractures.
methodsWe retrospectively reviewed 10 patients with Pipkin fractures treated by surgical hip dislocation and absorbable screw fixation at Foshan Traditional Chinese Medicine Hospital from December 2018 to March 2023. Demographics, Pipkin classification, and injured limb were recorded. All patients had at least 2 years of follow-up. Outcomes included fracture healing time, Modified Harris Hip Score (MHHS), and modified Merle d'Aubigné score. Complications, including avascular necrosis (AVN) and post-traumatic osteoarthritis (PTOA), were documented.
resultsAt final follow-up, the mean MHHS was 90.3 ± 6.8. Functional results were excellent in 7 patients, good in 2, and fair in 1 (excellent-to-good rate, 90%). Modified Merle d'Aubigné scores paralleled the MHHS. One patient with a Pipkin type III fracture developed AVN; no other major complications were observed. Patients with Pipkin types I and II achieved better functional recovery than those with types III and IV.
conclusionsIn treating Pipkin fractures, surgical hip dislocation provides adequate exposure while preserving femoral head vascularity. Bioabsorbable screws achieve stable fixation through their thread design and axial compression, supporting fracture healing. This technique shows promise as a treatment strategy for complex femoral head fractures.
