Introduction: Closed reduction and fixation using a cephalomedullary nail represents the accepted management of unstable intertrochanteric fractures. Cut-through has been described as a complication associated with the treatment. Although a hip arthroplasty may be the most predictable revision method, a non-prosthetic option can lead to similar results. The objective is to describe a non-prosthetic revision procedure in cases of cut-through.
Method: We performed a retrospective analysis of our Institutional Registry for Hip Fractures in elderly patients (RIAFC) from January 2010 to June 2018 searching for cut-through as a failure after unstable intertrochanteric fracture treatment. REVISION PROCEDURE: (A) Helical blade removal, introduction of structural bone graft (autologous or allograft) as a plug to obliterate the communication to the joint and a new blade insertion. (B) Same as in A but augmenting the blade/head purchase with poly(methyl methacrylate) (PMMA). Before the cement insertion, a radio-opaque solution was instilled to assure lack of joint leakage.
Results: We evaluated 1616 patients. Sixteen of them presented a cut-through complication (1%). Ten of them were females with an average age for all of 84 years. One patient denied an implant revision and opted for a total joint replacement. In four of the patients, the procedure A was done, 2 of them had a new failure, and an joint arthroplasty was performed. In the B group, only one patient needed a revision to a total hip. The other 10 patients healed uneventfully and did not need any further intervention.
Conclusion: Cut-through revision after fixation of unstable intertrochanteric fractures treated with cephalomedullary nail by blocking of the joint communication and augmenting the head blade purchase with PMMA is a safe and minimal invasive procedure, generates low blood loss and rate of complications and allows bone healing preserving the native joint.

Objective: Reverse obliquity intertrochanteric fracture is an unstable type of fracture. Current guidelines recommend intramedullary fixation, but there are still complications such as screw removal, hip varus, nail withdrawal, and nail fracture. The objective of this study was to use finite element analysis to compare the biomechanical properties of the novel proximal femoral bionic nail (PFBN), proximal femoral nail antirotation (PFNA), and combined compression interlocking intramedullary nail (InterTan) in the treatment of reverse obliquity intertrochanteric fractures (AO/OTA 31-A3.

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.
