Two cases of humeral fracture in Japanese Black calves treated with internal fixation using a dynamic compression plate

SummaryA long oblique osteotomy model of canine femoral fractures was created to compare six methods of internal fixation. The following methods were tested: three cerclage wires, three lag screws, eight-hole dynamic compression plate attached with six cerclage wires, eight-hole dynamic compression plate attached with six cortical screws, eight-hole dynamic compression plate attached with six cortical screws superimposed over three cerclage wires, and an eight-hole dynamic compression plate attached with six cortical screws superimposed over three lag screws. The repaired femurs were mounted in a mechanical testing machine in an orientation designed to mimic physiological loading. Axial compression was applied which resulted in the test specimens experiencing simultaneous compressive and bending forces. The effects of the method of osteotomy repair, bone temperature, and bone diameter were analyzed. The maximum load and the stiffness of the composite fixation and bones were determined. There were not any statistically significant differences in stiffness among the groups. All fixation methods, in which plates were attached with screws, resulted in significantly greater maximum load values than treatment techniques where plates were not used. None of the fixation methods attained a mean maximum load greater than 58% of the mean maximum load of the control femurs.Six methods of commonly used internal fixation methods are compared. A method of in vitro positioning of test femurs to mimic in vivo orientation is presented. Maximum load capabilities of fixation do not significantly increase with the addition of interfragmentary compression to plate fixation.

Objective: To determine the treatment outcome of the closed diaphyseal humeralfracture treated with dynamic compression plate at Liaquat university hospital Hyderabad.Materials and methods: Total 30 patients having displaced diaphyseal humeral fracture wereincluded in the study. All the patients having fracture of less than 10 days and between the ages15 – 45 years were selected. All the patients selected after counseling and diagnosed as a caseof closed diaphyseal humeral shaft fracture on the basis of clinical examination and X-rays.In this study dynamic compression plates (DCP) were used for stabilization of humeral shaftfracture as assessed by pre operative workup, operative findings and outcomes were recordedwith postoperative complications. To avoid the radial nerve palsy it is isolated during operativeprocedure. Results: Present study was comprises of 30 patients with humeral fracture with themean age of 30.29±8.92 years and male/ female ratio of 7:3. On the radiological findings mostcommon type of fracture was oblique in 54%. From the complications, postoperative pain wasfound in 6.6% of the cases along with postoperative Infections in 10%. 90% fractures unitedwhile 10% fractures found with non union. Excellent result were seen in 60% of the cases, while30% cases were noted with satisfied results and very poor results were found in 10% of thecases. Conclusions: It is concluded that DCP is the good option for the fixation of diaphysealhumerus fracture. Radial nerve palsy is less likely if isolated during operation.

Background: 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.Methods: 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.Results: 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%).Conclusions: 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.
