The recent trend in internal fixation of fractures puts a greater emphasis on biological fixation, which involves the use of locking plates and screws [1]. While conventional plates rely on frictional forces between the plate and the bone, locking plates utilize a threaded connection between screw and plate for fixation and stability [2]. Surgeons choose either type of fixation device in treatments for specific fractures and injuries.

Introduction: Volar locking plate represents the gold standard method of treatment of unstable distal end radius fractures. Objectives: The Present study aimed to identify the functional and radiological outcomes of distal radius fractures treated by open reduction and internal fixation using polyaxial volar locking plate. Patients and Methods: We reviewed 25 unstable distal end radius fractures that were operated in Orthopedic Department in Tanta University Hospital with polyaxial volar locking plates June 2018 to June 2019. The mean age of the patients was 40.8±14.34 years (range 24 to 65) and the mean duration of follow-up was 8.61 ± 3.19 months (range 6 to 17). All of the patients underwent open reduction and internal fixation with polyaxial locking plate through over flexor carpi radialis approach. After three months, pain, tendon functions, ROM, hand grip as well as radial median and ulnar nerves functions were well assessed. X-rays were done to assure full fracture consolidation. At the end of follow up, clinical results were evaluated according to Quick DASH Score. Castaign radiological assessment score was used for radiological evaluation. Results: There was a significant improvement in the functional indices from twelve weeks to the final follow-up. According to Castaign radiological assessment score 10 patients (40%) had excellent results, 14 patients (56%) had good results and 1 patient (4%) had fair results, no patients had poor results at the final follow up. Compared the performance of the polyaxial locking plate to another monoaxial plate and reported an improved range of radial and ulnar deviation with the variable angle device but they use another plate system. Conclusions: The use of polyaxial locking plates in treating unstable distal end radius fractures is associated with excellent to good functional results with minimal complications.

Volar Locking Plate

The present case report describe Open Reduction & Internal Fixation of a Distal Radius Fracture With a Volar Locking Plate. Anatomical reduction & stable fixation of fracture with or without bone grafting, greatly reduces the incidence of post-traumatic osteoarthritis & stiffness. The accuracy of fracture reduction co- relates directly to the final outcome. A 34-year-old man fell on his right outstretched h&. He presented to the casuality & on physical examination, he was noted to have deformity about his right wrist with moderate swelling. There was no neuro-vascular deficit. Various treatment modalities have been developed for distal radius fracture fixation. Treatment options range from closed reduction & cast application to open reduction with plates & screws. Locking plates address intra-articular & metaphyseal comminution. Biomechanical studies comparing volar fixed- angle locking plates with that of conventional dorsal plates report volar fixed-angled plates to be superior in terms of their strength.

Objectives: To determine frequency of union with orthogonal double locking plate in distal humeral fracture. Study Design: Descriptive, case series. Setting: Orthopedic department Punjab Medical College. Period: From April 2, 2017 to October, 2017. Material & Methods: 75 consecutive patients with distal humeral fractures were managed by open reduction of internal fixation with double locking plates in orthogonal configuration. Radiographic evaluation was done to see the callus formation after 12 weeks of treatment. Results: There were 54 (72%) males and 21 (28%) female patients having the average age 43.5±15.9 years. Union was seen in 71 (94.7%) patients. In 4 (5.3%) patients there was non-union. Conclusion: Anatomically pre-contoured distal humeral locking plates are useful in providing stable internal fixation for complex distal articular fractures, and hence allowing early rehabilitation.

Abstract Objective To explore the clinical effect of 3D printing combined with framework internal fixation technology on the minimally invasive internal fixation of high complex rib fractures. Methods Total 16 patients with high complex rib fractures were included in the study. Before the procedure, the 3D rib model was reconstructed based on the thin-layer chest CT scan. According to the 3D model, the rib locking plate was pre-shaped, and the preoperative planning were made including the direction of the locking plate, the location of each nail hole and the length of the screw. During the operation, the locking plate was inserted from the sternum to the outermost fracture lines of ribs with screws at both ends. In addition, the locking plate was used as the frame to sequentially reduce the middle fracture segment and fix with screws or steel wires. Chest x-rays or chest CT scans after surgery were used to assess the ribs recovery. All patients were routinely given non-steroidal anti-inflammatory drugs (NSAIDS) for analgesia, and the pain level was evaluated using numerical rating scale (NRS). Results The preoperative planning according to the 3D printed rib model was accurate. The reduction and fixation of each fracture segment were successfully completed through the framework internal fixation technology. No cases of surgical death, and postoperative chest pain was significantly alleviated. Five to 10 months follow up demonstrated neither loosening of screws, nor displacement of fixtures among patients. The lungs of each patients were clear and in good shape. Conclusion The application of 3D printing combined with framework internal fixation technology to the high complex rib fractures is beneficial for restoring the inherent shape of the thoracic cage, which can realize the accurate and individualized treatment as well as reduces the operation difficulty.

Tibial Pilon

Distal comminuted tibial fracture with or without intra-articular involvement is a very common injury of the lower limb, especially in younger patients due to high energy trauma. The anatomical and biomechanical properties of this segment of tibia, makes this pathology a major surgical challenge with a preserved clinical outcome. The aim of this study is to present different outcome of tibial fracture, treated with open reduction and internal fixation (ORIF) with titanium angle locking plates (ALP) and to underline the physiological and non-physiological bone healing effects on implants. In this study we included 48 patients with tibial pilon fracture who underwent to ORIF, applying ALP in the Orthopedics and Trauma department of the University Emergency Hospital in Bucharest. Due to preserved biomechanical properties of ALP and this anatomical region, weight bearing is not allowed till 6 to 8 weeks. Comminuted fracture of this part of tibia often have de-vascularized bony fragments which leads to delayed union or non-union. These complications often lead to implant failure, improper bone healing or non-union. Internal fixation with angle stable screws, offers a good stability of reduction in the early postoperative period. Titanium angle locking plates offers good anatomical reduction and stable fixation in the early period of healing process. Due to its rigid, fixed position of the screws in the plates, bone remodelling during healing process and early weight bearing, increases the mechanical failure of implant.Keywords: tibial pilon fractures, angle locking plates, implant failure.
