Progress on Diagnosis and Treatment of Ulna Coronoid Process Fractures / 中国微创外科杂志

ABSTRACT

[Summary] Ulna coronoid process fractures are not uncommon in clinical practice,but its treatment is difficult.Regan-Morrey type Ⅰ and Ⅱ fracture has no significant effect on the stability of the elbow joint,thus conservative treatment can be used.For some type Ⅱ fractures combined with elbow posterior dislocation,surgical treatment is required because of the potential danger of recurrent dislocation after reduction.Ulna coronoid process fractures often accompany other tissue injury,therefore manipulative reduction and external fixation with a cast or brace should be given as soon as possible.Once severe swelling complicated with bone fascia compartment syndrome,early decompression should be performed.The surgery can be carried out via medial approach,or in combination with lateral approach when lateral collateral ligament injury exists.Internal fixation materials include miniature titanium plate,micro screws,absorbable screws,hollow screw,anchor nail,external fixator and coronoid process of prosthetic replacement.
