This retrospective study addresses a series of 156 cases of forearm fractures. These 156 cases were managed in the trauma-orthopedic department (B4) of Fez University Hospital, Morocco, from May 2008 till January 2013. The purpose of this study is to analyze epidemiological and clinical factors of diaphyseal forearm fractures and the results of their treatment with dynamic compression plate (DCP), as well as the complications and therapeutic errors of this surgical technique. The frequency of hospitalization in the trauma-orthopedic department was 3,96%. Ages ranged between 16 and 83, the average age was 32. 132 patients were male (85%). 90% were managed at the day of trauma. Traffic accidents were the most frequent cause in 52% patients. The fracture was in the left forearm in 65% of patients. 53% of fracture lines were in the middle third of the forearm. 38 fractures were open, and 30 were admitted for polytrauma. Osteosynthesis was performed with dynamic compression plate for all patients. In comparison with the literature, our series shows the predominance of young male patients, with traffic accidents being the cause. Osteosynthesis with dynamic compression plate remains the treatment of choice that provides satisfactory results if the accuracy in this technique was respected.

Introduction: The human forearm serves an important role in upper extremity function, facilitating placement of the hand in space, thus helping to provide the upper extremity with its unique mobility Fractures involving the bones of forearm present unique problem not encountered with fractures of other long bones. Objective: To evaluate and compare the outcomes of locking compression plate (LCP) with limited contact dynamic compression plate (LC-DCP) for the treatment of adult diaphyseal both bone forearm fractures. Material and Methods: This study conducted in the Department of orthopedics, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from January 2018 to December 2020 included 20 patients with 40 fractures in each group. Patients were selected randomly to receive either LCP (20 patients, 40 fractures) or LC-DCP (20 patients, 40 fractures). Operative time, callus formation, functional outcome and complications were recorded. Results: Mean operative time did not differ significantly in the LCP and LC-DCP group (71.25 and 75.70 minutes respectively) .There was some difference in callus formation and mean time to bone union between the two groups which was significant. However, overall functional outcome did not differ significantly between both the groups. One case had delayed union in the (LC-DCP) group while one patient in each group developed superficial infection. Conclusion: In this prospective study comparing LCP with LC-DCP, the outcomes were equal in terms of final functional outcomes and mean operating time but LCP showed slight advantage in terms of callus formation and mean time to bone union.

<p class="abstract"><strong>Background:</strong> Forearm fractures are common nowadays because of road traffic accident. It is important to achieve anatomical reduction of both bone forearm fractures to regain function of upper limb. This study is undertaken to observe functional and radiological outcome using two different surgical modalities like dynamic compression plating (DCP), and intramedullary nailing in both bone forearm fractures and also to indivualize the optimal treatment method for different fracture pattern.</p><p class="abstract"><strong>Methods:</strong> Our study included 60 patients with diaphyseal forearm fractures in adults presenting to orthopaedic outpatient department. Among 60 patients, 30 patients underwent open reduction and internal fixation by dynamic compression plate and other 30 patients underwent closed reduction/open reduction by square nail after detailed pre-operative evaluation.<strong></strong></p><p class="abstract"><strong>Results:</strong> In our study average union time in DCP group is 23.39 weeks and square nail group is 28.89 weeks. Union in DCP group was 27 (90%) and square nail group 22 (73.33%). Delayed union in DCP group was 03 (10%) and in Square nail group was 6 (20%), non-union in DCP group was 0 (nil) and in square nail group was 2 (06%).</p><p class="abstract"><strong>Conclusions:</strong> Open reduction and internal fixation with DCP plates for both bone diaphyseal forearm fractures gives good results with early union rates. We also found that in open fractures and complex fracture like segmental fractures square nailing was better option compared to dynamic compression plate to reduce infection rates, retain periosteal blood supply from soft tissue. Thus we conclude that both implants are equally important and we should prioritize based on preoperative planning.</p>

Summary3.5 locking compression plate (LCP) fixation was compared to 3.5 limited contact dynamic compression plate (LC-DCP) fixation in a canine cadaveric, distal humeral metaphyseal gap model. Thirty paired humeri from adult, large breed dogs were separated into equal groups based on testing: static compression, cyclic compression, and cyclic torsion. Humeral constructs stabilized with LCP were significantly stiffer than those plated with LCDCP when loaded in static axial compression (P = 0.0004). When cyclically loaded in axial compression, the LCP constructs were significantly less stiff than the LC-DCP constructs (P = 0.0029). Constructs plated with LCP were significantly less resistant to torsion over 500 cycles than those plated with LC-DCP (P<0.0001). The increased stiffness of LCP constructs in monotonic loading compared to constructs stabilised with non-locking plates may be attributed to the stability afforded by the plate-screw interface of locking plates. The LCP constructs demonstrated less stiffness in dynamic testing in this model, likely due to plate-bone offset secondary to non-anatomic contouring and occasional incomplete seating of the locking screws when using the torque-limiting screw driver. Resolution of these aspects of LCP application may help improve the stiffness of fixation in fractures modeled by the experimental set-up of this investigation.
