Background: This study was done to observe the incidence of Osteo-line on the femur neck and to explore the clinical application of Osteo-line in osteotomy.
Methods: Eighty-nine adult femur specimens were selected to observe the incidence of Osteo-line on the femur neck. From August 2015 to January 2019, a total of 278 patients who completed unilateral hip arthroplasty at the Third Hospital of Hebei Medical University were retrospectively included.
Pilon fractures are always results of the high-energy trauma. They are often accompanied with serious soft tissue injury, and tension blisters happened in most cases. For comminuted fractures and poor soft tissue, how to select the incision is challenging.

We developed a new curved support plate (CSP) that can pass, via traditional anterolateral approach, through the superior tibiofibular interval and effectively support the posterolateral fragments. The purpose of our study was to determine the biomechanical reliability of the new plate and report the preliminary efficacy of the CSP for posterolateral tibial plateau fracture.

Previous investigations have sought to determine the curvature of the femur using the radius of the femoral bow. However, the radius of the curvature is affected by femur length.

Low- and middle-income countries contribute to only a small percentage of publications in multiple medical fields. Editorial bias was reported to be an important reason for this. However, whether this trend exists in leading spine journals remains unclear.

We first gathered radiological data of the proximal tibiofibular joint to verify the feasibility of the novel plate and provide an anatomical basis. MATERIAL AND METHODS Tomographic images of 98 healthy human tibias were obtained retrospectively.

Forty synthetic tibias were used to create posterolateral shearing tibial fracture models, which were randomly assigned to groups A-D. The fragments were fixed with two 6.

We compared range of motion (ROM), von Mises stresses on the implants, and stress on the intervertebral discs superior and inferior to the injured vertebra during simulated spinal movements.

This study investigated the relationship between size of greater tuberosity fragment and occurrence of IHNF in patients with shoulder dislocation and GTF.
Methods: A retrospective study was made to identify all patients presenting with shoulder dislocation with GTF between September 2014 and July 2016.
Background: A three-dimensional finite element model (FEM) of the knee joint was established to analyze the biomechanical functions of the superficial and deep medial collateral ligaments (MCLs) of knee joints and to investigate the treatment of the knee medial collateral ligament injury.
Methods: The right knee joint of a healthy male volunteer was subjected to CT and MRI scans in the extended position. The scanned data were imported into MIMICS, Geomagic, and ANSYS software to establish a three-dimensional FEM of the human knee joint.

Anterior dislocation of the sacroiliac joint, characterized by dislocation of the ilium anterior to the sacrum, is a subtype of complete posterior pelvic ring disruption. This injury occurs mostly in children. We present an adult patient with anterior dislocation of the sacroiliac joint.

Methods This retrospective study evaluated pre- and postoperative neurological status via Japan Orthopaedic Association (JOA) score. Surgical outcome was based on recovery rate percentage (RR%).
View Article and Find Full Text PDFBackground: Cephalomedullary Nail (CMN) is seen as the mainstay of internal fixation in femoral fractures. The purpose of the study was to present an accurate calculation method by simulating diverse anterior bow femoral models with finite element software. We hypothesized that anterior cortical penetration in distal femur would occur in patients whose femoral anterior bow was identified as too large for nailing by preoperative measurement of contralateral X-ray.

Comparing with the traditional open repair, the new technique provides obvious advantages of minimized operation-related lesions, fewer wound complications as well as a higher healing rate. However, a percutaneous technique without direct vision may be criticized by its insufficient anastomosis of Achilles tendon and may also lead to the lengthening of the Achilles tendon and a reduction in the strength of the gastrocnemius.

Distal locking screw prominence is one of the causes for soft tissue irritation. This study aimed to determine whether the use of the femoral condyles tangential views improve the diagnostic accuracy compared with anteroposterior (A-P) view in detecting distal locking screw penetrations during retrograde femoral nailing.

Systematic review and meta-analysis: searches of electronic databases 1980 to August 2014, checking of reference lists, hand searching of journals, and contact with experts. Randomized controlled trials (RCTs) in which surgical treatment was compared with nonsurgical treatment of displaced intra-articular calcaneal fractures from 1980 to 2014.

A 24-year-old male patient presented with one-month history of left lower back pain, which had been exacerbated for 10 days prior to admission. Magnetic resonance imaging (MRI) scans revealed an enlarged major psoas muscle that protruded into the inguinal region.

Methods: A retrospective review of 156 patients aged more than 65 years with femoral intertrochanteric fractures from December 2010 to December 2012 was performed. The patients were allocated to two groups: those treated with long nail (n=59) and short nail (n=97).
Background: Treatment of open calcaneal fractures remains to be a challenge for orthopaedic surgeons. The aim of this study is to assess factors affecting the treatment results of open calcaneal fractures.
Methods: A total of 98 patients who have 101 open calcaneal fractures were recruited in our hospital, they were all treated with a standard protocol based on the appearance of the traumatic wound.
Delayed healing or non-union of skeletal fractures are common clinical complications. Ibandronate is a highly potent anti-catabolic reagent used for treatment of osteopenia and fracture prevention. We hypothesized that local application of ibandronate after fracture fixation may improve and sustain callus formation and therefore prevent delayed healing or non-union.

We have not found any published clinical studies on the relationship between the integrity of the lesser trochanter and surgical outcomes of intertrochanteric fractures treated with intramedullary nails. The purpose of this study was to evaluate the impact of the integrity of the lesser trochanter on the surgical outcome of intertrochanteric fractures.

Background: Plastic deformation of the forearm is a rare and frequently missed injury in adults that can result in a significant loss of forearm rotation. The condition is reported mainly in Western countries; however, it is not uncommon in Eastern developing countries. We conducted a retrospective study of 30 cases of forearm deformation to find common factors to increase awareness of the condition in trauma doctors.

Methods: This prospective study used a visual analogue scale (VAS) to assess pain at the donor site at 1 month and 1, 3, 5 and 10 years postoperatively. Iliac regeneration status was recorded at 1, 3, 5, 7 and 10 years postoperatively by comparing plain radiographs.
