BackgroundLocking head systems are an additional option in the surgical treatment of metacarpal fractures. In this clinic 2.0 mm locking compression plates (LCP) are used, which provide the possibility of functional postoperative treatment even for complex and osteoporotic metacarpal fractures. For simple fractures and good bone quality the LCP system is used as a compression or neutralization plate. Depending on the type and localization of the fracture, different osteosynthesis techniques are used in order to achieve a functional postoperative treatment in as many patients as possible.Material And MethodsBetween July 2009 and December 2010 a total of 49 patients were enrolled in a prospective trial. All patients underwent surgical treatment with a 2.0 mm LCP system. Postoperative functionality of the hand was restored without immobilization. Clinical and radiological examinations were performed after 6 and 12 weeks and after 6 and 12 months with documentation of the range of motion (ROM), grip strength, fingertip to palm distance and the disabilities of the arm, shoulder and hand (DASH) score.ResultsAfter 6 months a good functional result was achieved in all patients with no cases of malrotation. Radiographs showed a completely consolidated bone healing.ConclusionAfter osteosynthesis with 2.0 mm LCPs all types of metacarpal fractures can be treated without immobilization.
