The treatment of medial collateral ligament and combined injury in the terrible triad of elbow / 中华骨科杂志

ABSTRACT

Objective To discuss the treatment strategy of medial collateral ligament and combined injury in the terrible triad of elbow.Methods The data of 21 patients with terrible triad of elbow who received treatment from February 2010 to April 2012 was retrospectively analyized.There are 17 males and 4females with12 cases left and 9 right elbows.The average age of them was 37.6 years (16-57).MRI examination was performed routinely,and used as guidance of treatment strategy of medial collateral ligament and combined injury.For the patients without or with partial damage of anterior bundle of medial collateral ligament(AMCL) injury while the continuity of ligament remains complete in MRI image,exploration and repair of the medial collateral ligament is not conventional.For the patients with MRI image showing AMCL avulsion or body disruption,we routinely used antero-medial approach to explore and repair,suture-anchors were used for suture the bony avulsion of the medial collateral ligament,body disruption of ligament and combined flexor-pronator teres complex injury were also be suture repaired.None of the patients used hinged external fixator during operation.A hinged brace was applied after operation.Results All patients were followed up for an average of 12.4 months (6-26).At the last follow-up,the average range of motion of the elbow was 135.2 ±10.2 degrees,average straight limited degrees,6.7±2.2 degrees,an average of 142±11.0 degrees of flexion.Mayo elbow performance score was 92 points (85-100).17 cases were excellent and 4 were good.Complications includeda transient ulnar nerve palsy in 3 cases,heterotopic ossification in 2 cases,tardive ulnar neuritis in 1 case,no elbow residual instability,dislocation,elbow stiffness and other complications.Conclusion Anterior bundle of medial collateral ligament avulsion or body disruption should be routinely suture repaired,which is in favor of restoring elbow immediate stability favoring restore elbow immediate stability.
