Purpose:
To evaluate the use of locking compression plates (LCPs) in diaphyseal forearm fractures.
Methods:
9 women and 23 men (mean age, 35; range, 12-70 years) with 45 forearm fractures were treated by open reduction and internal fixation with 3.5-mm stainless steel LCPs. All patients were followed up monthly until union; the mean duration being 20 months. Radiographic assessment was performed at 3, 6, 12, and 18 months. Clinical assessments regarding pain and function were undertaken at the final follow-up.
Results:
Two patients had delayed union but none had nonunion. There was no deep infection and only one superficial infection. Two refractures occurred after implant removal, both were of simple transverse type and at the sites of the original fractures. 33% of the fractures were reduced anatomically. 56% of the fractures healed with no or minimal callus formation and 44% with moderate callus formation. In total, 13% of the anatomically reduced fractures had moderate or abundant callus formation. 22 patients opted for removal of the implants (29 LCPs), after a mean of 16 (range, 9-21) months.
Conclusion:
The LCP is an effective bridging device used for treating comminuted fractures, but for treating simple fractures its superiority over conventional plating is yet to be proven.
