Objectives It was recently shown that biomechanical stability achieved with a locking compression plate (LCP) for ventral cervical fusion in horses is similar to the commonly used Kerf cut cylinder. The advantages of the LCP system render it an interesting implant for this indication. The goal of this report was to describe surgical technique, complications and outcome of horses that underwent ventral fusion of two or three cervical vertebrae with an LCP. Methods Medical records of eight horses were reviewed for patient data, history, preoperative grade of ataxia, diagnostic imaging, surgical technique and complications. Follow-up information was obtained including clinical re-examination and radiographs whenever possible. Results Two (n = 5) or 3 (n = 3) cervical vertebrae were fused in a mixed population with a median age of 9 months, median weight of 330 kg and median grade of ataxia of 3/5. A narrow 4.5/5.0 LCP (n = 6), a broad 4.5/5.0 LCP (n = 1) and a human femur 4.5/5.0 LCP (n = 1) were applied. Two horses were re-operated due to implant loosening. Six patients developed a seroma. Long-term complications included ventral screw migration in four, spinal cord injury in one and plate breakage in two horses at 720 to 1116 days after surgery. Outcome was excellent in three, good in four, poor in one patient. Clinical Significance The use of an LCP for ventral cervical vertebral fusion is associated with good clinical results. However, a careful surgical technique is required to further reduce the complication rate.

<p class="Default"><strong>Background: </strong>The optimal treatment of complex supracondylar femur fractures remains always challenging and controversial. the purpose of this prospective study was to evaluate the efficacy of distal femoral locking compression plate (DF-LCP) in terms of functional outcome and union rate for highly unstable complex supracondylar femur fractures and to determine the influencing factors of an unfavourable outcome.</p><p><strong>Methods:</strong> After obtaining approval from institutional ethics committee, 45 patients with complex supracondylar femur fractures were managed by open reduction and internal fixation with DF-LCP through lateral approach and as per standard protocol. The follow-up results were analysed clinically and radiologically, using the “Schatzker and Lambert criteria” at once in a month for first three months, once in three months up to one year and once in six months thereafter up to 2 years post-operatively.</p><p><strong>Results:</strong> In the present study, average duration of radiological union was 16 (range 12-22) weeks. The average range of motion of knee joint was 105 degrees. Out of 45 patients, clinical results were excellent in 48.9%, good in 17.8%, fair in 22.2% and poor in 11.1% patients according to Schatzker and Lambert criteria. Knee stiffness (7 cases), secondary arthritis (5 cases), and non-union (4 cases) were the main complications observed in this study, which were treated accordingly.</p><p><strong>Conclusions: </strong>DF-LCP holds the metaphyseal bone strongly and prevents metaphyseal collapse and mal-rotation in complex or highly unstable supracondylar femur fractures and simultaneously, it provides stable fixation to promote fracture union and allows early rehabilitation with acceptable complications.</p>

SummaryObjective: To evaluate retrospectively the effectiveness of the Locking Compression Plate® (LCP), in the form of either a straight or notched head T-plate, for the treatment of fractures of the distal radius and ulna in a series of 20 toy and miniature breed dogs.Methods: The medical records of toy and miniature breed dogs (<6 kg), greater than six months of age, with fractures of the distal radius and ulna from two veterinary hospitals were reviewed. The inclusion criteria included: fractures of the distal 1/3 of the radius and ulna and repair with open reduction and internal fixation utilizing an LCP (straight or notched head T-plate).Results: Twenty fractures (20 dogs) satisfied the inclusion criteria; eight straight and 12 notched head T-plates were used, either 2.0 mm (n = 13) or 2.4 mm (n = 7). Hybrid fixation was performed in all dogs in one or both fragments. Mean time to radiographic union was 6.9 ± 2.5 weeks (range: 4–12 weeks) in 18/20 dogs with radiographic follow-up. One complication was observed: infection that resolved with antibiotic medication and implant removal. No other major complications occurred by the time of last follow-up. In all cases (mean follow-up: 15 ± 7 months), the reported limb function as evaluated by the referring veterinarian or owner was excellent.Clinical significance: The LCP, used as a hybrid construct for the treatment of distal radial and ulnar fractures was shown to yield excellent clinical results with both uncomplicated healing and excellent functional outcomes in this series of toy and miniature breed dogs.

Two adult warmblood horses with a history of chronic hind limb lameness originating from the proximal interphalangeal joint (PIPJ) were presented at the equine hospital De Bosdreef (Belgium) between 2016 and 2017. Based on the case history and orthopedic examination, chronic osteoarthrosis (OA) of the PIPJ was diagnosed in both horses. A modified surgical arthrodesis of the PIPJ was performed using a central dorsal three-hole proximal interphalangeal locking compression plate (PIP plate) and four 5.5 mm transarticular cortical screws placed in a lag fashion (TCS-LF). The procedure resulted in an early bone bridging of the PIPJ and a return of the horses to the intended use within ten months after the surgery.

Category: Midfoot/Forefoot Introduction/Purpose: Midfoot arthrodesis remains a technical challenge. Little is known of the required magnitude of compression in order to obtain fusion. Multiple techniques have been reported, reflecting the difficulty of achieving a good result. These methods include an in situ bone graft dowel technique, dorsal staple, Kirschner wire, trans articular lag screw, and screw and plate fixation. More recently, dorsal hybrid plating, and slot graft inlay arthrodesis have been described. The purpose of this study is to describe the results of a dorsal fixed-angle locking compression plate in the setting of multiple-joint midfoot arthrodeses. Methods: A retrospective study was performed to identify 62 consecutive patients who underwent midfoot arthrodeses from June 2009 to May 2016. A total of 184 joints were spanned by dorsal fixed angle locking compression plates. The medical risk factors, etiology of arthritis, body mass index, time to union, visual analog pain scores (recorded preoperatively and postoperatively), and post-operative complications were evaluated. Patients were followed for one year. Radiographs were read by two fellowship-trained surgeons to determine the time to fusion. If union was indeterminate, a computed tomography scan was obtained, with the presence of 50% or greater bridging bone as the definition of fusion. Results: Of the joints spanned, 156 fused (83%). The average time to fusion was 19.6 weeks (Standard Deviation 21 weeks). Complications included persistent numbness (10), wound infection (2), and deep venous thrombus (1). The average VAS score diminished from 5.9 preoperatively, to 1.7 at week 6, 1.9 at week 12, 2.6 at month 6, and 3.1 at one year. Conclusion: Despite the difficulty of midfoot arthrodesis procedures in obtaining solid fusion, the dorsal fixed angle locking compression plate demonstrates a union rate, time to fusion, and complication rate that is comparable with the existing literature. The results of this study also indicate room for improvement in the design of advanced plating systems, which could incorporate more uniform joint compression combined with biologic augmentation in the hope of achieving improved radiographic and clinical results.
