OBJECTIVE: To compare the clinical and radiographic outcomes of bioabsorbable screw and metallic screw for Maisonneuve fracture. METHODS: The clinical data of 68 patients of Maisonneuve fracture treated with open reduction and internal fixation between October 2012 and October 2016 were retrospectively analyzed. Metallic screw fixation was used in 37 cases (group A) and absorbable screw fixation was used in 31 cases (group B). There was no significant difference in age, gender, weight, operated side, cause of injury, time from injury to operation, and complications between the two groups ( P>0.05). At last follow-up, the tibiafibular clear space (TFCS), tibiafibular overlap (TFO), medial clear space (MCS), and syndesmotic malreduction rate were recorded. And the dorsiflexion and plantar-flexion range of motion, pain visual analogue scale (VAS) score, ankle and hind foot score of American Orthopaedic Foot and Ankle Society (AOFAS), and Olerud-Molander (OM) score were recorded. RESULTS: All patients were followed up 25-43 months, with an average of 32.3 months. There was no significant difference in the operation time between the two groups ( t=1.229, P=0.282). All the fractures healed, and there was no significant difference in fracture healing time between the two groups ( t=1.367, P=0.413). At last follow-up, the syndesmotic malreduction rate of group A was 16.2% (6/37), showing no significant difference when compared with group B [6.2% (2/31)] ( χ 2=1.549, P=0.213). There were 3 complications in group A, 1 was superficial wound infection, 1 was local heterotopic ossification due to failure to remove the screws in time, 1 was local heterotopic ossification of the screws; and there were 2 complications in group B, 1 was rejection and 1 was local heterotopic ossification of the screws. There was no significant difference in the incidence of complications between the two groups ( χ 2=0.068, P=0.794). There was no significant difference in TFCS, MCS, TFO, ankle dorsiflexion and plantar-flexion range of motion, AOFAS score, OM score, and VAS score between the two groups at last follow-up ( P>0.05). CONCLUSION: Compared with metallic screw, absorbable screws provide adequate fixation and functional recovery with avoiding screw removal and lower syndesmotic malreduction.
