PURPOSE: Joint-line restitution is one objective of unicompartmental knee arthroplasty (UKA). However, the joint line is often lowered when resurfacing femoral implants are used. The aim of this study was to compare the joint-line height in UKA performed by robotic-assisted and conventional techniques. METHODS: This retrospective case-control study compared two matched groups of patients receiving a resurfacing UKA between 2013 and 2016 by either a robotic-assisted (n = 40) or conventional (n = 40) technique...

Condylar Hyperplasia (CH) is a self-limiting pathology condition that produces severe facial deformity at the expense of mandibular asymmetry. In this case report a 15-year-old female patient was diagnosed with Unilateral Condylar Hiperplasia (UCH) by mean of single-photon emission computed tomography (SPECT) and histological study. A high condylectomy in the right condyle was performed to stop the active status of the hyperplasia. A month after condylectomy, orthognathic jaw impaction and asymmetric mandibular setback surgery was performed with the Surgery First Approach (SFA)...

This original case report describes the morphologic changes caused by a mandibular condylar osteochondroma (OC) on a female patient and its treatment. The changes were identified by comparing her final records from a previous orthodontic treatment, without the presence of OC, to records taken before a second treatment, with a developed OC. The diagnostics and treatment for the OC and its consequences were described and discussed in this paper. Treatment included orthodontics with a lingual appliance, low condylectomy on the affected side, high condylectomy on the contralateral side, bilateral disc repositioning and orthognathic surgery...

Mandibular condylar cartilage (MCC) exhibits dual roles both articular cartilage and growth center. Of many growth factors, TGF-β has been implicated in the growth of articular cartilage including MCC. Recently, Asporin, decoy to TGF-β, was discovered and it blocks TGF-β signaling. Asporin is expressed in a variety of tissues including osteoarthritic articular cartilage, though there was no report of Asporin expression in MCC. In the present study, we investigated the temporal and spatial expression of Asporin in MCC...

Best treatment for paediatric patients with mandibular condylar fractures is still debated, and many approaches have been proposed. Closed treatment is the most used, but there is evidence showing long-term problems in patients with dislocated fractures. On the other hand, there are concerns on surgical treatment with open reduction internal fixation, particularly on the implanted hardware during growth. The aim of this study is to evaluate the long-term outcomes of paediatric patients treated surgically with external fixation...

Mandibular distraction for severe micrognathia in syndromic patients often leads to temporomandibular joint (TMJ) ankylosis, which requires further interventions to regain joint motion. The increased incidence of postdistraction ankylosis is likely related to increased prevalence of preoperative joint pathology in syndromic micrognathic patients. Previous studies have demonstrated that offloading the pressure on the condyle during the distraction process can prevent such TMJ pathology. In this article, the authors describe a successful new method for offloading the condyle to prevent postdistraction ankylosis using an external TMJ offloading device...

OBJECTIVE: Mandibular distraction surgery is a critical treatment for jaw deformity. However, abnormal mandibular condylar bone resorption is often seen as complication after surgery. Our previous study using a rat mandibular distraction model suggested that overloading leads to mandibular condylar resorption. Host factors are also believed to influence the resorption. To understand the relationship between host factors and resorption, we investigated the effect of changing bone mass and architecture on the mandibular condyle using FK506...

BACKGROUND: Ideal positioning and best coverage of the tibial base plate are essential in total knee arthroplasty. There are 2 types of tibial base plates: symmetric and asymmetric. The superiority of one to the other is still controversial. The aim of this study was to compare symmetric and asymmetric tibial base plates for total knee arthroplasty in terms of rotational alignment and coverage. METHODS: The study was conducted on a total of 80 cadaveric tibial bones...

Craniofacial morphology varies among individuals, which is regulated by the interaction between genes and the environment. Soft-diet feeding is a widely-used experimental model for studying the association between the skeletal morphology and muscle-related loading on the bone. Traditionally, these studies have been based on linear and angular measurements provided on two-dimensional (2D) radiographs in the lateral view. However, 2D observation is based on simplification of the anatomical structures and cannot detect three-dimensional (3D) changes in detail...

OBJECTIVE: Valid and reliable recording is a key requirement for accurately simulating individual jaw movements. METHODS: Horizontal condylar inclination (HCI) and Bennett's angle were measured using a digital jaw tracker (Cadiax® Compact 2) in 27 young adults. Three mounting methods (paraocclusal tray adapter, periocclusal tray adapter, and tray adapter with mandibular clamp) were tested. RESULTS: The mean values of the HCI differed by up to 10° between the mounting methods; however, the values for Bennett's angle did not differ substantially...

Total condylar resorption and the failure of bone synthesis material as postoperative complications of condyle fracture are seldom reported in the literature. When these occur, they may severely limit temporomandibular joint (TMJ) function. In such cases, a reconstruction of the joint is indicated, which can be achieved by means of an alloplastic prosthesis. This article reports a rare case of impaction of osteosynthesis material in the region of the base of the skull associated with a mandibular condyle fracture treated with rigid internal fixation, which resulted in complications...

A 68-year-old woman presented with generalized seizure due to the left internal carotid artery (ICA) aneurysmal compression of the ipsilateral medial temporal lobe. Computed tomography angiography (CTA) revealed multiple aneurysms of the right persistent primitive hypoglossal artery (PPHA), the right ICA, and the right anterior cerebral artery (ACA). The right PPHA originated from the ICA at the level of the C1 and C2 vertebral bodies and passed through the hypoglossal canal (HC). The PPHA aneurysm was large and thrombosed, which was located at the bifurcation of the right PPHA and the right posterior inferior cerebellar artery (PICA), projecting medially to compress the medulla oblongata...
