Magnesium-based bioabsorbable screw fixation for hallux valgus surgery – A suitable alternative to metallic implants

Is There a Role for Absorbable Metals in Surgery? A Systematic Review and Meta-Analysis of Mg/Mg Alloy Based Implants

“…In the other studies, the radiographic evaluation showed no difference between the Mg and Ti group [ 7 , 10 , 22 , 33 ] ( Table 2 ).…”

“…After analysis of the inclusion criteria, eight articles were eligible, which 468 patients were included (control group or experimental group), with 230 screws of Mg. The age of patients included in all studies was 48.14 years [ 7 , 10 , 11 , 21 , 22 , 33 , 34 , 47 ]. The main results are summarized in Table 1 .…”

“…Of the eight studies selected, six studies were related to the hallux region [ 7 , 10 , 21 , 22 , 33 , 34 ], one related to the treatment of necrosis of the femoral head [ 11 ] and last one related to mandibular condyle fracture [ 47 ]. All studies used screws for fixation.…”

“…Five studies compared Mg and Ti screws related to the treatment of hallux fracture [ 7 , 10 , 22 , 33 , 34 ], one study used Mg screw compared to a control group with no graft fixation [ 11 ], and two studies had no control or comparison group [ 21 , 47 ] ( Table 1 ).…”

“…Elderly patients and those suffering from chronic systemic conditions, such as diabetes, osteoporosis, and other bone metabolic disorders, have an increased potential for poor outcomes and worse complications from the management of these injuries. In orthopedic and oral and maxillofacial surgical specialties, plates and screws are used to stabilize the fractured bone fragments [ 4 , 6 , 7 , 8 , 9 ], and the most commonly used material is commercially pure Ti (CPTi) and its alloys, especially Ti grade 5 (Ti-6Al-4V). Other metals have also been used, for example, cobalt-chromium-molybdenum alloys, as well as stainless steel.…”
