ObjectiveTo compare extra-articular and intra-articular olecranon osteotomy in treating intercondylar fractures of the distal humerus managed with open reduction and internal fixation regarding the functional outcomes and complications. MethodsBetween September 2008 and December 2010, 36 patients with intercondylar fractures of the distal humerus were treated by open reduction and internal fixation using the trans-olecranon approach. Among the, 21 underwent extra-articular olecranon osteotomy and 15 accepted intra-articular olecranon osteotomy. The mean follow-up time was three years. We compared the elbow function, the rate of no non-union or delayed union and the rate of postoperative complications between the two groups. ResultsThe elbow function and Mayo elbow performance scores were good at the latest follow-up. There was no non-union in all osteotomies. We found significant difference in delayed union (P=0.01) and traumatic arthritis rate (P=0.02) between the two groups. ConclusionExtra-articular olecranon osteotomy is better for bone union and the decrease of traumatic arthritis rate.
ObjectiveTo explore the therapeutic effect of using locking compression plate (LCP) as an external fixator and using an external fixator on open fractures of the tibia. MethodsBetween September 2010 and December 2012, 56 patients with the open tibia fractures underwent external fixation using LCP as an external fixator (LCP group, n=22) or external fixator (external fixator group, n=34). We compared the healing time, the rate of postoperative complication and the postoperative function between two groups. ResultsThe mean healing time was 11 weeks (8-28 weeks) and there was 1 case of delayed healing in the LCP group. The mean healing time was 14 weeks and there was 4 cases of delayed healing in the external fixator group. We found significant difference in the healing time (t=2.740, P=0.008) and the infection rate of pin track (13.6% vs 32.4%; χ2=2.496, P=0.114) between the LCP and external fixator group. ConclusionFor open fractures of the tibia, using LCP as an external fixator may increase the healing time and decrease the rate of postoperative complications.
