“…12 Intra-articular steps larger than 5 mm are considered to have a significant risk of secondary arthrosis, 2,3,11,12,18,20 and residual joint incongruity of as little as 3 mm is associated with poor functional outcome. 2,18,20 Although most authors recommend open reduction and internal fixation for displaced glenoid fractures, 3,11,12,18,20,28 arthroscopically assisted fixation in case studies has been described with good clinical results. 1,8,10,34 Our study was conducted to further develop techniques for arthroscopically assisted percutaneous fixation of glenoid fractures and, in particular, to assess the risks of neurovascular injury.…”
