Study of role of limited contact dynamic compression plates versus locking plates in long bone fracture management

Abstract

<p class="abstract"><strong>Background:</strong> Present study was conducted to assess the functional, radiological, clinical factors associated with long bone fractures stabilized with limited contact dynamic compression plating (LC-DCP) and locking plates.</p><p class="abstract"><strong>Methods:</strong> In this retrospective observational study conducted over 2 years, 60 osteoporotic patients undergoing surgery for diaphyseal fractures of long bones at the study centre were studied. Two groups were formed on the basis of usage of LC-DCP plate or the locking plate in fracture management. Participants were thoroughly evaluated clinically. Radiographic assessments included evaluation of callus formation and fracture fragments after the functional load. Functional outcome was assessed based on the range of movements and the ability to carry out daily activities. Disabilities of the arm, shoulder and hand (DASH) score was also calculated. Post-operative follow-ups were conducted at 6 weeks, 12 weeks and 1 year.<strong></strong></p><p class="abstract"><strong>Results:</strong> Radius or ulna were the commonest site of fracture with more than half (35, 58.33%) patients affected with 93.3% having middle 1/3<sup>rd</sup> diaphysis fracture. There were no significant differences between the genders for site or location of fractures. DASH scores were comparable in both groups. The mean union time was significantly higher among females (9.76±2 weeks) than males (8.59±1.21 weeks). Most patients took 14-16 weeks to achieve the functional outcome, with LC-DCP observed to provide faster functional recovery.</p><p><strong>Conclusions:</strong> Radius or ulna fractures are the commonest amongst long bone fractures, with middle 1/3<sup>rd</sup> diaphysis being the commonest site of affection. LC-DCP facilitates slighty faster fracture union and functional recovery than locking plates, with union time being significantly longer in females.</p>
