Erythropoietin as promoter of engraftment for treatment of radius/ulnar non-union fracture in a dog: Case report.

Background: Fractures with large bone defects and non-unions are a great challenge for veterinary orthopaedists. In small dog breeds, this complication is commonly encountered in fractures of the radius and ulna due to poorer vascularisation of the distal antebrachium region. Case Description: A case of radius/ulnar non-union in a 1.5-year-old Pinscher occurring after trauma and two successive unsuccessful osteosyntheses is described. During the operative revision, after the removal of existing bone implants, the bone defect was filled with cortical autologous bone graft. Autocancellous bone mixed with erythropoietin was applied proximally and distally to the cortical autograft for stimulation of bone healing. The post-operative period was without complications. As early as the 9th post-operative week, the animal was able to bear weight on the limb, without signs of lameness, pain, and swelling. Radiologically, a very good bridging of the graft was observed. Fifteen weeks after the operative revision, the fracture was completely healed with excellent clinical outcome. Conclusion: The application of autogenous cortical bone graft and cancellous autograft mixed with erythropoietin demonstrated an excellent therapeutic effect and resulted in complete regeneration of the large bone defect over a 15-week period.

Good functional recovery after bilateral elbow dislocation associated with bilateral distal radius and ulna fractures.

Bilateral elbow dislocation associated with bilateral distal forearm fractures is extremely rare, therefore its optimal treatment, complications, and outcomes remain unclear. We present an illustrative case with a 2-year follow up of a patient who sustained a complex injury of the upper extremity and underwent combined surgical and conservative treatment.

A rare case of peri-implant distal radius fracture.

A peri-implant fracture near the volar plate of distal radius represent a very rare injury. The main factor of this lesion is high energy trauma on the wrist. We report a case of a 61-year-old woman with a peri-implant fracture located just proximally to the plate and a fracture of the ulnar head that occurred after a simple fall. The patient was surgically treated by plate and screws removal. The fracture was fixed using a longer volar plate for the radial fracture and a plate for the head ulnar fracture. Different factors such as osteoporosis, BMI and screw position could influence the fracture pattern. However, considering growing use of plates for distal radius fracture fixation, the frequency of these kind of fracture will probably increase.

Non-operative Management of Adult Both Bone Forearm Fractures - A Case Report and Literature Review.

INTRODUCTION: Adult both bone forearm fractures (BBFF) are common injuries that are typically treated with operative fixation given their instability. Non-displaced fractures can be theoretically treated non-operatively, but there is no literature demonstrating treatment outcomes of such fractures. CASE REPORT: We present a case of non-displaced BBFF in a 23-year-old Caucasian male adult who was treated with cast immobilization and concomitant ultrasound stimulator use; this patient went on to have solid fracture healing without complication. CONCLUSION: Based on this case, we demonstrate that non-operative management of non-displaced BBFF in adult patients is an option if close follow-up is available. This is significant for the fields of both orthopedic and plastic surgery, as there is little concrete evidence of outcomes of such non-displaced fractures in hand surgery literature.

The efficacy and safety of combination therapy of low-intensity pulsed ultrasound stimulation in the treatment of unstable both radius and ulna fractures in children.

BACKGROUND: There are few reports of Low-intensity pulsed ultrasound (LIPUS) treatment for fresh forearm fractures in children. OBJECTIVES: LIPUS stimulation was applied after surgery of forearm fractures in children and the efficacy and safety of combination therapy of LIPUS treatment were evaluated. PATIENTS AND METHODS: Children with both radius and ulna fracture, twenty-five diaphysis (mid-R&U) and nineteen metaphysis (dist-R&U) fractures, were treated with intramedullary nailing followed by cast and splint mobilization. Thirteen patients in the mid-R&U fracture group and eight patients in the dist-R&U fracture group were combined with LIPUS stimulation postoperatively. RESULTS: Periosteal callus appeared significantly earlier after surgery in the LIPUS-treated groups than in the groups without LIPUS treatment. The duration of external fixation was significantly shorter in the dist-R&U fracture group treated with LIPUS stimulation compared with that in the mid-R&U fracture group without LIPUS treatment. Furthermore, the time span needed for bone union in the groups with LIPUS stimulation was significantly shorter than in the groups without LIPUS stimulation. CONCLUSIONS: It is suggested that LIPUS stimulation can lead to a reduction of treatment periods of unstable forearm fractures safely after operation even in children.
