Distal radius re-fracture with bending of implant and neurovascular compromise

A Retrospective analysis of peri-implant fractures: insights from a large volume clinical Study

PURPOSE

Peri-implant fractures (PIFs) are a concept in evolution for which different diagnostic criteria have been proposed and modified over time. They have not been extensively reported. PIFs are usually located in the distal part of previous osteosynthesis, where fragile bone is in contact with the rigid implant and are a significant complication after orthopaedic surgery, which requires careful management and treatment. This clinical study presents findings from a retrospective analysis of PIF's, providing description of characteristics and outcomes. They provide information about the associated risk factors and description of the effectiveness of various treatments.

MATERIALS AND METHODS

A retrospective analysis was performed in a clinical study involving patients with PIFs. Data from medical records, radiographic images, and surgical reports were collected and analyzed. The study included patients with refracture of pre-existing osteosynthesis admitted to the hospital between 2015 and 2022. Demographic information, fracture characteristics, surgical interventions, and post-operative outcomes were assessed. Each case was followed for a minimum of one year after surgery, and a critical analysis was performed by senior surgeons. Furthermore, the PIFs were classified according to the type of initial implant and the position of the new fracture in relation to the original implant.

RESULTS

Between 2015 and 2022, out of 18,813 fractures treated at a Level 1 traumatology hospital, a total of 85 patients with PIF's were identified. Fracture characteristics varied, including location, fracture pattern, and implant type. Most of the PIFs, 71 cases (83.53%), occurred in the femur. Additionally, there were seven cases (8.24%) involving the humerus, four cases (4.71%) affecting the tibia/fibula, two cases (2.35%) in the radius, and one case (1.18%) involving the clavicle. Surgical management was the primary attitude in treatment. Various techniques were used, including the use of longer and stronger implants to achieve high-quality fixation, facilitating early rehabilitation and return to previous activities. Postoperative complications after surgery for PIFs were observed in 16 cases (18.8%).

CONCLUSIONS

Peri-implant fractures (PIF) are a distinct topic and a challenging condition with a high rate of postoperative complications. Complications after the second surgery may be severe and life threatening in older patients. A classification can be useful to make decisions about the optimal treatment in different anatomic areas and type of implant used for primary osteosynthesis. Currently there are no standardized protocols for management, therefore each case should be carefully discussed and planned before surgery.

Peri-implant distal radius fracture due to car collision

Peri-implant fractures have gained increasing importance in orthopedics as the number of surgical procedures involving orthopedic implants rises globally. These fractures pose a significant challenge in terms of diagnosis, treatment, and postoperative management. They manifest as stress fractures distal to the implant site. Developing an effective treatment strategy involves evaluating multiple influencing factors. This article presents a rare case of a peri-implant distal radius fracture in a 63-year-old man, with no comorbidities, resulting from a car accident, classified as C1U in the Michele D'Arienzo system. The surgical intervention included plate fixation for the radius and wire fixation for the ulna. The wire was used for ulna instead of a plate, due to skin injuries, with good results. As life expectancy rises and individuals remain active in their elder years, the incidence of peri-implant fractures is expected to increase. Factors such as the implant type, surgeon's approach, and patient-specific elements may influence peri-implant fracture occurrence. The widespread use of plate fixation for distal radius fractures may also contribute to a parallel increase in such fractures. Providing detailed context and specific case presentation allows better understanding and implications for clinical practice.

Peri-Implant Distal Radius Fracture: Proposal of a New Classification

A peri-implant fracture near the volar plate of the distal radius represents a rarity and can be associated with a mechanical failure of the devices. A literature review was conducted including all fractures that occurred around a volar wrist plate, which could be associated with an ulna fracture. All articles published until December 2021 were considered according to the guidelines presented in the PRISMA Statement. The search was conducted with the PubMed electronic database, Cochrane Database of Systematic Reviews, Medline, Embase, and Google Scholar. Only nine cases of these fractures were reported in the literature. The causes could be due to delayed union/non-union of the old fracture after low energy traumas, high energy trauma in patients with poor bone quality, or hardware mechanical failure. Furthermore, the literature review of peri-implant radius fracture shows different level of radius fracture and types of implant failure. In accordance with these different cases, a new classification of peri-implant fracture of the distal radius is proposed.

Successful Closed Reduction of Distal Radius Volar Locking Plate Plastic Deformation with Associated Fracture: A Case Report

CASE

Distal radius fractures are among the most common orthopaedic injuries. The volar locking plate is now the most utilized internal fixation method for these fractures. There are few reports of mechanical failure of volar locking plates within the literature. In this case report, we describe successful closed reduction of traumatic volar locking plate plastic deformation with associated fracture. In addition, we discuss existing literature regarding plastic deformation of distal radius plates.

CONCLUSION

Traumatic, plastic deformation of distal radius volar locking plates with associated fracture may be managed nonoperatively with closed reduction.

Closed Management of a Distal Radius Refracture Through a Bent Volar Plate: Can an Open Procedure be Avoided?: A Case Report

CASE

A 55-year-old man sustained a distal radius fracture, which was fixed with a volar plate 20 years ago. He then fell from 2 m and sustained a refracture with a bent but intact volar plate. A manipulation under anaesthetic/anaesthesia was attempted. Satisfactory reduction was confirmed and maintained, with bony union confirmed at 6 months. Regular follow-up showed continuing functional improvement.

CONCLUSION

This rare case avoided surgical intervention and its associated risks and costs. Attempted closed reduction can be considered a treatment option before open revision fixation, with demonstrated ability for fracture healing in an acceptable position.
