condyle fracture

PURPOSE: Hoffa fracture is a femoral condyle fracture in the coronal plane. The lateral condyle is more commonly involved. The diagnosis is often difficult to detect with routine radiographs. Conservative management in this type of fracture resulted in nonunion, malunion, and other complications, such as stiff knee. Therefore, surgical management is mandatory in displaced fractures. Previous studies suggest only application of cancellous screw fixation, but these are not enough to counter vertical shear stress...

OBJECTIVE: This work aimed to evaluate the results of using a 2-stage surgical treatment strategy without doing anterior transposition of the ulnar nerve (ATUN) for cases with long-standing nonunited fracture lateral humeral condyle (LHC) in children, accompanied by a critical review. METHODS: A consecutive 12 children with a long-standing ">2 years" nonunited LHC with evident radiologic gross anatomic distortion of the elbow were included in this study. A 2-stage surgical treatment strategy was applied, wherein the first stage, open functional reduction, osteosynthesis, and iliac bone graft were done...

We aimed to establish a new method of obtaining femur anteroposterior radiographs from live rats. We used five adult male Sprague-Dawley rats and created a femoral fracture model with an 8 mm segmental fragment. After the surgery, we obtained two femoral anteroposterior radiographs, a novel overhead method, and a traditional craniocaudal view. We obtained the overhead method three times, craniocaudal view once, and anteroposterior radiograph of the isolated femoral bone after euthanasia. We compared the overhead method and craniocaudal view with an isolated femoral anteroposterior view...

Mandibular condyle fracture malunion and tooth loss can cause functional and esthetic problems. A patient with restricted mouth opening associated with muscle atrophy required prosthetic rehabilitation. Since the remaining teeth had a poor prognosis and the patient had difficulty adapting to the interim denture, complete mouth rehabilitation with implants was chosen. The implants were placed by using nerve lateralization and an autogenous bone graft. Prosthetic rehabilitation combines digital diagnosis and conventional prosthetic restorations...

Bilateral defects around the knee joint following fracture of the proximal tibia (Schatzker type V & VI) are difficult to reconstruct because of the unavailability of local tissue. A bicondylar proximal tibial fracture requires a bilateral approach and dual plates for fracture fixation. Because of extensive dissection during plating and extended zone of trauma, the suture lines occasionally dehisce resulting in soft tissue defects on both sides of the proximal tibia. Because of its bilateral nature, the defect requires 2 flaps...

Penetrating injuries to the musculoskeletal system pose common challenges for orthopedic surgeons in emergency departments (EDs). The complexity escalates when a joint is affected, increasing the risk of severe complications such as infection and post-traumatic arthritis. Given the potential importance of these injuries, early diagnosis and a meticulous treatment plan are crucial. In this paper, we present a unique case of penetrating trauma, resulting in an intra-articular defect on the lateral femoral condyle of an adolescent girl...

Cementless unicompartmental knee arthroplasty (UKA) has a lower rate of radiolucency in postoperative follow-up than cemented UKA. However, the rate of tibial plateau fracture, one of the complications, has been reported to be higher in cementless UKA than in cemented UKA. We report four cases of postoperative tibial lateral condyle fractures after cementless Oxford UKA. Four patients underwent cementless Oxford UKA. Immediate postoperative radiography and CT showed no fracture lines. At five to six weeks postoperatively, MRI showed a fracture line from the intersection of the longitudinal and transverse tibial osteotomies through the lateral pinhole to the end of the lateral tibial diaphysis...

Ipsilateral hip and knee dislocation is a rare and complex injury that usually results from high-energy trauma. Only 14 cases were reported in the literature so far. We report the case of a 35-year-old man who presented with an ipsilateral right hip and knee dislocation after being involved in a road traffic accident. A contralateral floating knee was associated. The hip dislocation was associated to a posterior wall fracture of the acetabulum and a femoral head fracture. The knee dislocation was compound and associated with a patella fracture...

Tibial plateau fractures (TPFs) are orthopedic challenges with multiple injury modalities and clinical presentations. TPFs are often classified using the Schatzker classification system, which can dictate management. In our case, a 37-year-old male presented at an orthopedic specialty hospital with right knee pain after a fall from a truck ramp. X-rays and CT imaging demonstrated a comminuted bicondylar TPF in the emergency room with metaphyseal dissociation. The patient was placed in a knee immobilizer, made non-weight bearing, and scheduled for outpatient follow-up with a local orthopedic surgeon...

BACKGROUND: Vascularized medial femoral condyle (MFC) bone graft is useful for pseudarthrosis and osteonecrosis, but has the risk of fracture as a complication. This study aimed to create multiple three-dimensional (3D) finite element (FE) femur models to biomechanically evaluate the fracture risk in the donor site of a vascularized MFC bone graft. METHODS: Computer tomography scans of the femurs of nine patients (four males and five females) with no left femur disease were enrolled in the study...

(1) Background: Anatomically pre-contoured plates usually require only minimal or even no intraoperative contouring. For complex cases, such plates also assist the surgeon as an anatomical template during fracture reduction. In this study, we present our experience of using a 3D printing technology for the treatment of bicondylar humeral fractures in feline cadavers. (2) Methods: Surgeries were performed on 15 pairs of front limbs amputated at the scapula. The limbs were obtained from 15 adult cats without obvious pathology of the skeleton...

OBJECTIVE: To determine the influence of screw configuration on the reduction and stabilization of simulated complete lateral condylar fracture. STUDY DESIGN: Randomized experimental crossover study. METHODS: A lateral condylar fracture was simulated in 18 cadaver limbs from nine horses. Each limb underwent repair with 4.5 mm diameter cortex screws, tightened to 4 Nm, in a linear and triangular configuration. Computed tomography (CT) of each repair was performed with the limbs in unloaded and loaded conditions...

BACKGROUND: The current literature lacks recommendations regarding surgical approaches to best visualize and reduce Hoffa fractures. The aims of this study were to (1) define surgical corridors to the posterior portions of the lateral and medial femoral condyles and (2) compare the articular surface areas visible with different approaches. METHODS: Eight fresh-frozen human cadaveric knees (6 male and 2 female donors; mean age, 68.2 ± 10.2 years) underwent dissection simulating 6 surgical approaches to the distal femur...

BACKGROUND: Poorly controlled postoperative pain results in prolonged length of stay (LOS). The use of liposome bupivacaine injectable suspension (LB) for postoperative pain control is a relatively recent practice. PURPOSE: The purpose of this study was to investigate the following. In patients undergoing open reduction and internal fixation of mandibular fracture(s), does the use of LB reduce LOS compared with regular bupivacaine? STUDY DESIGN, SETTING, SAMPLE: We implemented a retrospective cohort study of consecutive patients with mandibular fracture(s) presented to Grady Memorial Hospital in Atlanta, GA, from January 2021 to January 2022...

STUDY DESIGN: Retrospective Observational Study. OBJECTIVE: Mandibular condyle fractures are distinctive among maxillofacial injuries in which they disrupt mandibular function in a way that other traumatic injuries do not. Condylar fractures can be treated using either the conservative (closed reduction and immobilisation) or surgical (open reduction and internal fixation) approaches. Both of these modalities of treatment have advantages and disadvantages, as well as indications and contraindications...

(1) Background : Mandibular fractures are common, with the condylar process being a frequent site of injury, accounting for 25-45% of cases. This research aims to assess the mechanical suitability of various plates for high-neck condyle fractures. (2) Methods : Polyurethane models mimicking high-neck condyle fractures were utilized in this study. Sixteen distinct plate designs, constructed from titanium sheets, were tested. The figures underwent force assessments on a durability testing apparatus, and the relationship between used force and fracture movement was documented...

BACKGROUND: To investigate the biomechanical effects of screw orientation and fracture block size on the internal fixation system for Letenneur type II Hoffa fractures. METHODS: The fracture models were randomly divided into six groups according to the fracture subtypes and the direction of nail placement, and a plumb line of the posterior condylar tangent was made across the base of the posterior femoral condyle. The fracture blocks of the three types of fracture were calculated and recorded in the sagittal position, and the biomechanical performance of the six groups was evaluated by biomechanical tests...

BACKGROUND: Distal humerus elbow fractures are one of the most common traumatic fractures seen in pediatric patients and present as three main types: Supracondylar (SC), lateral condyle (LC), and medial epicondyle (ME) fractures. AIM: To evaluate the epidemiology of pediatric distal humerus fractures (SC, LC, and ME) from an American insurance claims database. METHODS: A retrospective review was performed on patients 17 years and younger with the ICD 9 and 10 codes for SC, LC and ME fractures based on the IBM Truven MarketScan® Commercial and IBM Truven MarketScan Medicare Supplemental databases...
