[Clinical effect of allogeneic peroneal bone marrow support combined with plate fixation for the treatment of Neer type Ⅳ proximal humeral fractures].

Objective: To explore clinical effect of allogeneic peroneal bone marrow support combined with plate internal fixation in treating Neer type Ⅳproximal humeral fractures.

Methods: From December 2017 to December 2020,12 patients with Neer type Ⅳ proximal humeral fractures were treated with allogeneic peroneal bone marrow support combined with plate internal fixation,including 7 males and 5 females,aged from 56 to 78 years old;the time from injury to operation ranged from 1 to7 days. Operative time,fracture healing time and complications during follow-up were observed,and clinical efficacy was evaluated by Constant-Murley score at the latest follow-up.
