Objective: Although a large body of evidence has reported on surgical approaches for the treatment of unstable intertrochanteric femoral fractures, studies that comprehensively evaluate treatment outcomes are limited. The purpose of this study was to compare the effectiveness of extramedullary fixation (i.e., dynamic hip screw [DHS]), intramedullary fixation (i.e., the proximal femoral nailing [PFN]), and hemiarthroplasty (HA) for the treatment of unstable intertrochanteric femoral fractures using network meta-analysis.
Methods: This study meets the preferred reporting items for systematic reviews and meta-analyses criteria. The Patient, Intervention, Comparison and Outcome search protocol framework was used to search the Google Scholar, PubMed, Embase, and Cochrane Library databases were searched from inception until June 2023.
Results: A total of 15 randomized controlled trials, including 1282 patients were analyzed. The Harris hip score (HHS) after DHS fixation was the lowest compared with that of PFN fixation and HA. DHS fixation had a significantly longer operation time than that of PFN fixation. Compared with HA, a lower incidence of superficial wound infection was observed with PFN and DHS fixations. PFN was significantly more likely to be implant cut out compared with HA. Compared with DHS, PFN and HA showed a lower incidence of fracture healing malunion.
Conclusion: HA and PFN have good efficacy in improving the HHS and preventing joint deformities. However, HA showed a higher incidence of superficial infection than that observed with PFN, whereas a higher risk of screw cutout is observed with PFN than with HA.

The aim was to study the independent risk factors of internal fixation failure in proximal femoral anti-rotation intramedullary nailing for intertrochanteric femur fracture, and to build a nomogram prediction model accordingly. Clinical data of patients with intertrochanteric femoral rotor fractures admitted to the First People's Hospital of Longquanyi District from January 2018 to January 2023 were retrospectively collected. The occurrence of spiral blade cut out, internal fixation breakage, peri-internal fixation fracture, hip internal rotation deformity, and fracture nonunion within 1 year after surgery were included in the internal fixation failure group, and the rest were included in the internal fixation success group.

Fractures of the trochanteric mass represent a significant proportion of hip fractures. These fractures often occur in the elderly due to compromised bone quality, leading to a high predisposition for instability at the fracture site. The study was conducted through a retrospective analysis of 1,259 hospitalizations in the Department of Orthopedics and Traumatology of the Bucharest University Emergency Hospital between 2022 and 2023, including patients with various types of trochanteric mass fractures: basicervical, per trochanteric, intertrochanteric, subtrochanteric, and trochanter-diaphyseal fractures.

Objectives: This study aimed to investigate the importance of the Dorr index in the preoperative evaluation of implant failure in patients who underwent proximal femoral nail (PFN).
Patients And Methods: This retrospective study examined 312 patients who underwent PFN for intertrochanteric fractures between January 2016 and January 2020. Patients with unstable fractures according to the AO/OTA (AO Foundation/Orthopaedic Trauma Association) classification, those over 65 years of age, with at least one year of regular follow-up, a tip-apex distance <25 mm, and a caput-collum-diaphyseal angle between 125° and 135°, were included.

Bone healing after sliding hip screw internal fixation of intertrochanteric hip fractures is difficult to monitor with radiography. In this study, we describe and evaluate a device to non-invasively determine the loading on the screw implant as a possible qualitative indicator of bone healing. A novel load-sensing sliding hip screw (LS-SHS) was fabricated containing a radio-dense tungsten indicator rod that moves and can be measured within the screw cannulation when the screw bends under load via plain radiography.
