摘要

Purpose

Pipkin 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.

Methods

We 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.

Results

At 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.

Conclusions

In 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.
