Pterygoid hamular bursitis is a rare craniofacial pain syndrome used to describe palatal and pharyngeal pain due to an enlarged pterygoid hamulus. The pterygoid hamulus is a hook-shaped bony process located bilaterally on each medial pterygoid plate of the sphenoid bone, posterior and medial to each maxillary tuberosity. These processes project downward and anterolaterally; serve as attachment for ligaments and a network of muscles. It can be palpated in patients with a finger palpating the posteromedial to maxillary tuberosity. The pathogenesis is elusive and varies from bursitis of tensor veli palatine, elongated pterygoid hamulus, persistent trauma to the mucosa overlying the pterygoid hamulus. The clinical features include strange chronic sensation, burning, swelling, and erythema of the pterygoid hamulus region. The pain often radiates to pharynx, ipsilateral face and sometimes radiating to temporal region making it difficult to diagnose from headache, temporomandibular disorders, and dental infections like pericoronitis. The anatomical neighboring structures in relation to oropharyngeal region may give a misleading diagnosis to dentist in case of Pterygoid Hamulus Bursitis. The understanding of pterygoid hamulus anatomy and its relation to surrounding structures is necessary to get the correct diagnosis of the inflammatory or traumatic pain in oropharyngeal region.

The calcanail system is a novel intramedullary approach for calcaneal fractures but is believed to be insufficient to treat complex fractures. We propose a modified Calcanail technique by adding a transfixation screw to improve stability. The aim of this study was to evaluate the biomechanical stability of the modified Calcanail system and compare it with the traditional Calcanail system and plate fixation. A Sanders type-IIIAB calcaneal fracture model was built and simulated fixation with the three implants. A vertical loading of 700 N was applied to the subtalar joint surfaces, and the posteroinferior calcaneal tuberosity was fixed. Construct stiffness, fracture migration, and von Mises stress were assessed. The results showed the modified Calcanail system demonstrated the highest construct stiffness, smallest migration, and lowest von Mises stress among three fixations. The study suggested that the modified Calcanail system can provide comparatively sufficient stability, that makes it preferable to treat complex calcaneal fractures.
- The effect of build angle on the tissue surface adaptation of maxillary and mandibular complete denture bases manufactured by digital light processing. [Journal Article]
- JPJ Prosthet Dent 2019 Jun 18
- CONCLUSIONS: In both arches, the difference of overall tissue surface adaptation was not statistically significant in the 4 different build angles. However, the color deviation map revealed that the 135-degree build angle may be appropriate in the maxillary DLP-printed denture base and the 100-degree angle, in the mandibular denture base.

Musculoskeletal models used in gait analysis require coordinate systems to be identified for the body segments of interest. It is not obvious how hindfoot (or rearfoot) axes defined by skin-mounted markers relate to the anatomy of the underlying bones. The aim of this study was to compare the marker-based axes of the hindfoot in a multi-segment foot model to the orientations of the talus and calcaneus as characterized by their principal axes of inertia. Twenty adult females with no known foot deformities had radio-opaque markers placed on their feet and ankles at the foot model marker locations. CT images of the feet were acquired as the participants lay supine with their feet in a semi-weight bearing posture. The spatial coordinates of the markers were obtained from the images and used to define the foot model axes. Segmented masks of the tali and calcanei were used to create 3D bone models, from which the principal axes of the bones were obtained. The orientations of the principal axes were either within the range of typical values reported in the imaging literature or differed in ways that could be explained by variations in how the angles were defined. The model hindfoot axis orientations relative to the principal axes of the bones had little bias but were highly variable. Consideration of coronal plane hindfoot alignment as measured clinically and radiographically suggested that the model hindfoot coordinate system represents the posterior calcaneal tuberosity, rather than the calcaneus as a whole.
- Derotational femoral osteotomy changes patella tilt, patella engagement and tibial tuberosity trochlear groove distance. [Journal Article]
- KSKnee Surg Sports Traumatol Arthrosc 2019 Jun 18
- CONCLUSIONS: Derotational femoral osteotomy has a significant impact on patella tilt and axial patella engagement. Moreover, TTTG distance is slightly changed by a derotational femoral osteotomy, which has to be taken into account preoperatively when considering surgical procedures.

This study aimed to obtain screening data on the maturity status of the tibial tuberosity in schoolchildren of higher elementary school grades for risk management of Osgood-Schlatter disease (OSD). The maturity stages and cartilage thicknesses at the tibial tuberosity were determined by ultrasonography on the occasion of a school-based musculoskeletal examination for 124 grade 5-6 elementary schoolchildren, and their associations with the students' demographic characteristics and OSD were examined. The time-dependent changes of the maturity status of the tibial tuberosity were also examined in grade 5 students (n = 26) by a longitudinal survey. The cross-sectional survey showed that the epiphyseal stage was reached in 89% of girls and 35% of boys. The girls who had experienced menarche (n = 28) were all in the epiphyseal stage and had a decreased cartilage thickness (p = 0.004, after adjusting maturity stages). Students with OSD (n = 5) were all girls in the epiphyseal stage, and only two of them had an increased cartilage thickness. During the longitudinal survey, a marked increase in cartilage thickness from the previous measurement was observed in three boys (without clinical symptoms) and a girl who newly developed OSD. Two students with OSD without chronic pain had thin cartilage. In conclusion, for schoolchildren of higher elementary school grades, the risk of OSD is higher among girls with the epiphyseal stage. Cartilage thickness may not contribute to the diagnosis of OSD, since thick cartilage is not very common in OSD. However, cartilage thickness may reflect the status of OSD.
- Critical shoulder angle and greater tuberosity angle according to the partial thickness rotator cuff tear patterns. [Journal Article]
- OTOrthop Traumatol Surg Res 2019 Jun 12
- CONCLUSIONS: A large critical shoulder angle was associated more with articular-sided PTRCTs than bursal-sided PTRCTs. A large greater tuberosity angle was associated more with bursal-sided PTRCTs than with articular-sided PTRCTs. Both critical shoulder angle and greater tuberosity angle were positively associated with the occurrence of full thickness rotator cuff tears.
- The radiographic morphology of the greater tuberosity is associated with muscle degeneration in patients with symptomatic rotator cuff tears. [Journal Article]
- JSJ Shoulder Elbow Surg 2019 Jun 12
- CONCLUSIONS: For patients with rotator cuff tears, the presence of GT spurs or sclerosis on radiographs predicted the occurrence of supraspinatus and infraspinatus muscle atrophy, as well as supraspinatus fatty infiltration, based on MR images. The clinical relevance is that MR imaging is suggested for patients with radiographic GT sclerosis or spurs to detect advanced rotator cuff lesions.

- A Re-Evaluation of the Gritti-Stokes (Above-Knee) Amputation for the Non-Ambulatory Patient. [Journal Article]
- AVAnn Vasc Surg 2019 Jun 11
- CONCLUSIONS: A reevaluation of the Gritti - Stokes amputation is warranted in the United States as an alternative to the traditional above knee amputation whenever possible. Our experience with a small series of Gritti-Stokes amputations has yielded promising advantages including potential for decreased blood loss, and fewer complications in the postoperative period when compared to the standard above knee amputation (AKA). Retained muscle attachments facilitate increased limb function, and allows use of slide joint prosthetics, which are gaining popularity for ambulatory patients. The thickened skin and subcutaneous tissues overlying the patella, and the posterior incision, have the potential benefit of protection against trauma and osteomyelitis seen with traditional AKA were the open ended medullary bone is deep to the incision. We believe that for these same reasons the GSA should be considered in the non-ambulatory patient as well.
