Periprosthetic knee fractures following total knee arthroplasty are increasing proportionally to the number of primary procedures done. We performed a retrospective review of Rorabeck type II fractures treated with a retrograde nail, trying to find the relationship between failure and the number of distal locking screws used. Twenty-six patients were included. The number of distal interlocking screws (patients with one or two distal interlocking screws and patients with three screws) correlated with nonunion (p < 0.1), did not correlate with the malunion rate (p > 0.1) and correlated with the reintervention rate (p < 0.1).

A Novel Technique With Buttress Plating for Comminuted Base Fractures of the Proximal Phalanx.
Ann Plast Surg

Department of Orthopaedic Surgery, Duson Hospital, Ansan, Korea.
Background: Extra-articular but severely comminuted distal basal fractures of the proximal phalanx (PP) are rarely reported. Therefore, the aim of this study was to achieve proper union and desirable outcomes using low-profile locking plates/screws. We introduced our own surgical approach and reported the clinical/radiographic outcomes via retrospective case series.

Purpose: Although several techniques have been described for bent intramedullary nail removal, there is no universally accepted strategy. We hypothesized that a device based on the action principle of a three-point bend fixture could facilitate extraction of bent intramedullary nails; this paper describes its design and experimental testing.
Methods: Five large synthetic left femurs and five steel intramedullary nails were used.
Higher interfragmentary compression force improves lateral tibial plateau fracture stability using locking plate fixation: experimental and simulation verification.

Background: This study investigated the impact of higher interfragmentary compression force (IFCF) on the stability of locking plate fixation in lateral tibial plateau fractures.
Methods: Biomechanical experiments and finite element analysis (FEA) were employed to compare the performance of the AO cancellous lag screw (AOCLS) and a newly developed combined cancellous lag screw (CCLS).
Results: The results demonstrated that the CCLS provided a higher IFCF without the risk of over-screwing, significantly improving fixation stability.
Investigation of the safety of position-based titanium plate fixation for costal cartilage injuries.
World J Surg
December 2024
Department of Cardiothoracic Surgery, The Third Hospital of Shijiazhuang City, Shijiazhuang, China.
Background: Costal cartilage injuries are unappreciated, and there is a paucity of reports on fixation methods. This study aims to evaluate the safety of titanium plate internal fixation for costal cartilage injuries.
Methods: A retrospective analysis was conducted on 30 patients with costal cartilage injuries who underwent titanium plate internal fixation between April 2016 and November 2022 at our hospital.
Article Synopsis
- The study investigates the effectiveness of two types of bone grafts (packed cancellous vs. corticocancellous) used in repairing scaphoid waist nonunion fractures with volar locking plates.
- Postoperative CT scans showed that 95% of patients achieved osseous bridging, but those with packed cancellous grafts had significantly better healing outcomes than those with corticocancellous grafts.
- The findings suggest that using packed cancellous autografts may lead to faster and more effective bone healing in these cases.
