Safe corridors for sacroiliac fixation in pediatric patients.
Eur J Orthop Surg Traumatol
December 2024
Introduction: Pelvic ring fractures are rare in the pediatric population and can be treated using sacroiliac screws when needed. The aim of this study was to identify safe anatomical corridors for sacroiliac fixation in different pediatric age groups and also to determine the prevalence of sacral dysmorphism in the study sample.
Method: We measured the dimensions of the horizontal and oblique S1 corridors and the horizontal S2 corridor in pelvic computed tomography scans of 138 children aged 1 to 16 years.
Introduction: Proximal femur fractures are common in older patients and typically require surgical treatment, with cephalomedullary nails being the gold standard device for this approach. This study aimed to identify the factors associated with the failure of cephalomedullary nailing.
Materials And Methods: We retrospectively evaluated 380 patients treated with a cephalomedullary nail between August 2021 and August 2022 in a trauma referral center in Brazil.
Unlabelled: Distal femoral metaphyseal fractures are rare in children, and the proximity of the fracture to the growth plate makes their approach challenging.
Objective: Evaluate outcomes and complications of treatment of distal femoral metaphyseal fractures in children with proximal humeral locking plates.
Method: Retrospective study between 2018 and 2021, including seven patients.
Objectives: The primary objective of the present study is to compare the radiographic outcomes and complications of two different techniques for lateral closing-wedge osteotomy in pediatric patients with cubitus varus.
Methods: We retrospectively identified patients treated at five tertiary care institutions: 17 underwent the Kirschner-wire (KW) technique, and 15 patients were treated with the mini external fixator (MEF) technique. Demographic data, previous treatment, pre- and postoperative carrying angle (CA), complications and additional procedures were recorded.
Avascular Necrosis After Modified Dunn Surgery for the Treatment of Slipped Capital Femoral Epiphysis.
Rev Bras Ortop (Sao Paulo)
October 2022
The present study analyzed the incidence of epiphyseal avascular necrosis in patients with slipped capital femoral epiphysis (SCFE) treated using a modified Dunn technique. In addition, this study determined the correlation of other variables with this incidence and described treatment complications. This is a retrospective study with 20 patients treated by the same surgical team from 2009 to 2019 and followed up for 2 to 12 years.

Methods: Retrospective study between 2001 and 2019. We collected the patients' general information, clinical and radiographic data, and complications after the following three-step treatment: (1) fixation of the Salter-Harris II fracture of the triplane fracture, (2) fixation of the Salter-Harris II/IV fracture with cannulated screws, and (3) fixation of the tibial fracture with flexible titanium nails.
Objective: To report surgical techniques and results in the treatment of chronic Monteggia fracture-dislocation in children.
Methods: Six pediatric patients who had undergone a procedure involving the following 6 crucial surgical steps were retrospectively evaluated: 1- extended lateral approach, 2- fibrotic removal, 3-proximal ulnar osteotomy, 4- reduction of the radial head and transcapitellar temporary fixation, 5- ulnar fixation with a straight plate shaped according to the deformity generated by temporary fixation, and 6- transcapitellar Kirschner wire removal.
Results: Four patients were women, and four showed the right-sided compromise.
Purpose Of Review: Tarsal coalitions may cause painful pes planovalgus and recurrent sprains, and can lead to arthrosis if improperly managed. In this review, we discuss the current topics related to talocalcaneal and calcaneonavicular coalitions.
Recent Findings: Tarsal coalitions are initially managed with conservative therapy, and when this approach fails, surgery is performed.
Purpose Of Review: The chronic Monteggia may lead to pain, mobility limitation, progressive valgus deformity, lateral elbow instability, late ulnar nerve paralysis, and degenerative changes. In this review, we discuss the current procedures in the literature focused on correcting chronic Monteggia to avoid these complications.
Recent Findings: Correction of the ulnar deformity with elongation and angulation of the ulna in the opposite direction of the dislocation of the radial head is the most important factor for the reduction and consequent preservation of the radial head.
Objective: To report a series of cases of patients treated by fracture of the femoral head through the Ganz pathway with controlled dislocation of the hip.
Method: All patients who were surgically treated with a Ganz access route for femoral head fractures were identified in a tertiary referral service for trauma. A review of medical records with X-rays and CT scans was carried out.
Purpose Of Review: Femoroacetabular impingement (FAI) post slipped capital femoral epiphysis (SCFE) may lead to degenerative changes on the hip. We have reviewed the current procedures in the literature, aiming to correct the SCFE to prevent FAI and the ones that treat FAI post SCFE.
Recent Findings: The trends of managing moderated or severe SCFE is to correct the displacement by reduction and fixation with articular hematoma decompression in unstable hips and Dunn modified procedure even for unstable and stable situations.
Objective: To present our experience and preliminary results from using controlled hip dislocation to treat cam-like femoroacetabular impingement, in teenagers and young adults with sequelae of slipped capital femoral epiphysis.
Methods: This was a retrospective analysis on 15 patients who were treated in a tertiary-level hospital between 2011 and 2013. The following data were collected for analysis from these patients' files: demographic data, surgical procedure reports, joint mobility evaluations, patients' perceptions regarding clinical improvement and whether they would choose to undergo the operation again, previous hip surgery and complications.
Objective: To determine the application of the modified Oxford score among patients with proximal femoral epiphyseal slippage (PFES) as an aid to indicating prophylactic surgical treatment on the contralateral hip.
Methods: Retrospective analysis on the medical files of patients attended at the institution where the authors work. From these, patients attended between 2008 and 2011 who presented unilateral PFES and were followed up for a minimum of two years were selected.
Objective: To evaluate the indications, epidemiology, associated lesions, complications and prognosis among children with unstable femoral diaphysis fractures who were treated with titanium elastic intramedullary nails.
Method: This was a retrospective analysis on 24 patients aged 5-12 years with unstable femoral diaphysis fractures who underwent surgical treatment with elastic titanium intramedullary nails at the Cajuru University Hospital, Curitiba-PR, between April 2002 and March 2008, with a minimum follow-up of 36 months. The epidemiological data, angular deviations, leg shortening and bone consolidation were evaluated.
