Fatigue failure of bones of the metacarpo-phalangeal (fetlock, MCP) joint is common in thoroughbred racehorses. Stresses within the fetlock joint cartilages are affected by the morphology of the third metacarpal bone (MC3) and proximal phalangeal bone, and the steepness of the median sagittal ridge of MC3 is believed to be associated with fracture. This study investigated the influence of the steepness of the sagittal ridge on cartilage stress distribution using a finite element model of the joint. Changes to the steepness of the sagittal ridge were made by applying a parabolic function to the mesh, creating four different models with sagittal ridge angles ranging from 95° to 105°...

Condylar fractures are among the most frequent fractures in the context of traumatic lesions of the face. The management of condylar fractures is still controversial, especially when fractures occur in children: if overlooked or inappropriately treated, these lesions may lead to severe sequelae, both cosmetic and functional. The therapy must be careful because severe long-term complications can occur. In this case report, the authors present a case of mandibular fracture in which the decision between surgical therapy and functional therapeutic regimen may be controversial due to the particular anatomy of the fracture line and the age of the patient...

INTRODUCTION: Supracondylar fractures are the most common elbow injuries in skeletally immature children between 5-10 years of age and cubitus varus deformity is the most common late complication. Cubitus varus or bow elbow or gunstock deformity is the result of malunion occurring as a complication of supracondylar fracture of the humerus. Various type of corrective osteotomies are used of which lateral closed wedge French osteotomy is commomly used which has its own complications like lateral condylar prominence, unsightful scar and limitation of movement...

BACKGROUND: This is to assess one of the rare complications after total knee replacement and to assess risk factors of failure. METHODS: 11 patients with varus knee and an average age of 67 years underwent TKA between 2005 and 2013. All patients returned with a sudden sharp knee pain, disability to walk and significant decrease in ROM about 4 to 8 weeks after surgery. Radiographic examination revealed a lateral femoral condylar stress fracture. RESULTS: After analyzing the images, we found common characteristics among all patients, which might be attributable to the later fracture including varus deformity>25, femoral component lateralization, and valgus correction...

Facial fractures in children are rare. Lack of pneumatization, fat pockets, mixed dentition, contribute to the elasticity and bone stability. When mandibular fractures occur in children, most often involve the condyle by indirect trauma. Such fractures are the center of discussion on the form of treatment if this should be performed conservatively, or held the reduction and fixation of the fracture with surgical exposure of the fragments. In condylar fractures in children, in most patients, the proposed treatment is closed reduction...

BACKGROUND: Rehabilitation using an implant supported overdenture with two implants inserted in the interforaminal region is the easiest and currently accepted treatment modality to increase prosthetic stabilization and patient satisfaction in edentulous patients. The insertion of implants to the weakend mandibular bone decreases the strength of the bone and may lead to fractures either during or after implant placement. The aim of this three dimensional finite element analysis (3D FEA) study was to evaluate the biomechanical effects of implant diameter in case of facial trauma (2000 N) to an edentulous atrophic mandible with two implant supported overdenture...

BACKGROUND: Constrained condylar knee (CCK) prosthesis are common used for revision surgery but can also help surgeons to improve implant stability in primary knee arthroplasty, in fact in severe knee arthrosis with serious deformity associated with a significant instability a more constrained articulation is required. With introduction of second generation of semi-constrained prosthesis, rate of complication is real decreased and a good survival rate and functional score results is showed...

It is difficult to fix fractures of the condylar head of the mandible. Several techniques have been described which show satisfactory outcomes, but stability can be questionable, and some can cause irritation of the soft tissues. We describe a technique and first results of treating such fractures with resorbable magnesium-based headless bone screws (Magnezix(®) 2.7mm CS; Syntellix AG, Hanover, Germany).

A 7-year-old boy presented to the emergency department with bilateral bloody otorrhoea after falling from his scooter. Skull base fracture was suspected. CT showed no evidence of skull base fracture but bilateral mandibular condyle and external acoustic canals fractures. We report this case to illustrate a rare possibility of bilateral external acoustic canal fracture associated with condylar fracture in trauma patients presented with bloody otorrhoea.

We present a rare fatal complication of an occipital condylar fracture. The patient was initially neurologically intact, but showed secondary clinical deterioration. Imaging revealed extensive extra-axial hemorrhage at the craniocervical junction and an acute obstructive hydrocephalus. MR imaging demonstrated a T2 hyperintens signal in both the lower brainstem and upper cervical spinal cord, likely caused by the extra-axial hemorrhage. As prognosis was estimated infaust, supportive treatment was discontinued and the patient died soon thereafter...

BACKGROUND/AIM: There is no data available to show whether there is a relationship between mandibular fractures and isolated fractures of the posterior and/or latera wals of the maxillary sinus. The aim of this study was to determine whether there is a coincidence between these fracture patterns. METHODS: Four hundred large volume cone beam computed tomography scans (CBCT) of patients with a fracture of the mandible between 2008 and 2013 were analyzed retrospectively...

PURPOSE: Third molars (M3s) have been hypothesized to be associated with the risk of mandibular angle fracture and mandibular condylar fracture. The authors systematically estimated the relative risk (RR) of M3 status for the development of mandibular angle fracture and mandibular condylar fracture through a meta-analysis of cohort studies. MATERIALS AND METHODS: In this systematic review, the PubMed, EMBASE, and Cochrane Library databases were searched from inception to October 2016...

Fractures of the upper limbs are frequent and often need operative treatment in addition to a well-indicated conservative management. This depends on the maturity of the nearest growth plate and the local remodeling potential, which is dependent on age. Following conventional x‑ray imaging an individual prognostic growth analysis leads to the therapeutic decision. Around the elbow and the shaft of the forearm, criteria are stricter than near the shoulder or wrist. Gilchrist or Desault bandages as well as braces are adequate for most subcapital and humeral shaft fractures...

PURPOSE: To evaluate the response of mandibular osteomyelitis treated by surgical decortication with disruption of the affected adjacent periosteum in concert with long-term targeted antibiotic therapy. The hypothesis is that, by removing the buccal cortical plate and disrupting the hypertrophically inflamed adjacent periosteum, the medullary bone will be brought in contact with bleeding tissue and circulating immunologic factors and antibiotics, which will promote definitive resolution...

BACKGROUND: A coronal fracture of the posterior femoral condyle, also known as a Hoffa fracture, is an unusual injury, and there are only a handful of case reports or series exploring it. The optimal fixation method of these intraarticular fractures remains controversial; improper or unstable fixation usually lead to an unsatisfactory prognosis. The use of posterior-anterior or reversed lag screw fixation is still a popular method. Additional buttress plating is also recommended for fixation of these difficult fractures...
