Use Of Locking Compression Plate Research Articles

Use of Locking Compression Plate and Locking Compression T-Plate for Surgical Arthrodesis of the Carpometacarpal and Distal Tarsal Joints in 13 Horses.

The aim of this study was to describe the use of the locking compression plate (LCP) and locking compression T-plate (LCTP) in cases of carpometacarpal and distal tarsal arthrodesis for the treatment of osteoarthritis and small carpal or tarsal bone fractures, and to document clinical outcomes. Case records of horses treated with carpometacarpal or distal tarsal arthrodesis via internal fixation using an LCP or LCTP between 2013 and 2021 were reviewed. All cases were evaluated retrospectively. Follow-up information was gained via phone conversation with owners and referring veterinarians. Data were collected for 13 horses that fulfilled the study criteria. A total of eight horses underwent distal tarsal arthrodesis, and five underwent carpometacarpal arthrodesis. Twelve of thirteen horses went back to some level of athletic performance. Eight of 13 returned to the same level, while 4 of 13 returned to a lower level. Minor postoperative complications were recorded in 3 of 13 cases, with all horses suffering manageable short-term complications returning to the same level of work. Two horses suffered a major complication, with one resulting in euthanasia. Carpometacarpal and distal tarsal arthrodesis performed using the LCP and LCTP allowed all surviving horses in the study to obtain immediate postoperative comfort and eventual return to use.

Study of functional outcome of two, three and four-part proximal humerus fracture fixation with locking compression plate using Neer`s score

Proximal Humerus fractures are one of the commonest fractures occurring in the orthopedics. They comprises of approximately 4-5% of the fractures at the hospital and are secondary only to hip fractures and distal end radius fractures in the elderly group. The incidence is approximately 3 per 1000 persons in a year and is rapidly increasing with age. They are common in elderly patients after cancellous bone of the humeral neck has weakened due to old age, but these fractures can be seen in any age group. The most serious fractures and fracture-dislocations are often seen in active middle aged patients. These fractures can be extremely disabling and their management often demands expertise surgical skills and judgment. 2 Because of increasing incidence of high energy trauma complicated patterns of fracture in proximal humerus are becoming increasingly common. The preferred treatment varies depending on the age of patient, bone quality, expertise surgical team and the patient’s expectations. There is a controversy regarding the best method of treating displaced proximal humerus fractures. Treatment options for displaced fractures include open reduction and internal fixation. Neer recommended Open reduction & internal fixation for 2- and 3-part fractures. Most of the poor results following open reduction and internal fixation of these fractures are due to imperfect surgical techniques. In a three or four-part fracture dislocation when the Humerus head is entirely devoid of any blood supply it can be replaced by prosthesis. This study is about the use of Locking Compression Plate to fix fractures of the proximal humerus in adult patients in whom the duration of hospital stay reflects the earning capacity of the person and in elderly in whom immobilization of upper-limb is associated with stiffness, reflex sympathetic dystrophy, and shoulder-hand syndrome.

IMPROVING LCP STABILITY THROUGH A DESIGN MODIFICATION: A COMPUTATIONAL INVESTIGATION

Femoral shaft fractures are common in both the young and the elderly due to high-impact trauma and low-impact trauma respectively. Its treatment by indirect reduction through the use of Locking Compression Plates (LCP) has been on the rise. However, there have been several cases of plate breakage [Kanchanomai, et al, 2008] and fracture non-unions to warrant a study of what measures can be taken to improve its stability. We studied a design modification of the LCP whereby screw holes that are unused are removed from the plate. The stability of the modified LCP is compared with the existing LCP by comparing their performance across different fracture lengths.

The efficacy of treatment of unstable distal radial fractures with locking compression plate

Objective To explore the clinical effect of treatment of unstable distal radial fractures with locking compression plate ( LCP ).Methods 122 patients with unstable distal radial fractures who were used as study subjects were randomly assigned to a study group or a control group,61 for each group.The study group underwent open reduction and internal fixation with use of locking compression plate,whereas the control group received simple plaster external fixation.The efficacy was compared between the two groups.Results In the study group, all the patients recovered smoothly and had no severe postoperative complications with good functional recovery and a rate of91.8％ for Cooney score;as compared with the patients in the control group, there were significant differences ( P ＜ 0.05 ).Conclusions Locking compression plate for unstable distal radial fractures is efficacious and safe and plays an important role in improvement in quality of life.It is worth applying clinically.

Use of Locking Compression Plates for Long Bone Nonunions Without Removing Existing Intramedullary Nail: Review of Literature and Our Experience

Exchange nailing of ununited fractures with or without bone grafting is the most acceptable procedure for nonunion with previously implanted intramedullary nails. Though excellence of this procedure has been well documented for diaphyseal, noncomminuted fractures of long bones, its acceptability for distal femoral, metaphyseal-diaphyseal junctional fractures, and humeral locations is doubtful. A method of obtaining stability at fracture site is described wherein locking compression plates are applied over the ununited fracture with bone grafting without removal of the underlying nail. Eleven patients (six males, five females) with ununited fracture of long bones were enrolled. All these patients had previously undergone locked intramedullary nailing for fractures of long bones (seven femur, two humerus, two tibia). Fracture site was exposed, surfaces rawed, and locking compression plate (AO Synthes) was applied over the intramedullary nail. Eccentric position of the plate allowed one or two bicortical screws adding to the stability of the construct. Interlocking screws if broken were also replaced during the same sitting. Autologous bone grafting was done in all cases. All fractures showed radiologic union at 6.2 months. No complications were encountered. Locking compression plating of ununited fracture with preexisting intramedullary nails has predictable good results for specific indications.
