Online ahead of print. ABSTRACT PURPOSE: Defining normal anthropometric ranges of proximal femur and femoral head for each age group in children/adolescents is a necessity when differentiating normal anatomical variants from pathological deformities. Aim of this study is to define a set of normal anthropometric parameters based on 3D-CT measurements in normal asymptomatic children/adolescents and analyse the vari ations arising depending on age, side, and/or gender. METHODS: Morphology of the proximal femur was retrospectively assessed in 170 hips (85 children, < 15 years). Measurements included covered femoral head volume (CFHV), femoral head diameter (FHD), femoral head extrusion index (FHEI), coronal alpha angle (CAA), lateral centre-edge angle (LCEA), anterior (AOS) and posterior head-neck offset (POS) and femoral neck-shaft angle (FNSA). Correlation analyses as well as inter- and intra-rater reliability were performed. RESULTS: CFHV, LCEA, FHD and AOS/POS increased with age and FHEI, CAA, and FNSA decreased with age. None of the measurements correlated with the side. AOS showed a poor correlation with gender. Rapid growth phases were observed at the age of 1, 7 and 11. The inter- and intra-rater reliability was high (range ICC 0.8-0.99 Cronbach alpha 0.86-0.99). CONCLUSION: This data delivers a description of growth phases as well as gender and age-correlated refere nce values of the proximal femoral morphology that could be used by paediatricians and orthopaedic/paediatric surgeons to early diagnose proximal femur deformities and provide guidance in the planning of possible operations.

Medial patellar plica syndrome

xlomafota13 shared this article with you from Inoreader Medial patellar plica syndrome Via Neuroradiology Cases Clinically young patient with anteromedial knee pain. MRI shows a well-defined low signa l intensity band running across medial patellofemoral recess. However there is no obvious associated bone marrow oedema involving medial articulating facet of patella or medial femoral trochlea.  Associated joint effusion. Medial plica mentioned in the report with joint effusion. Medial plica syndrome Synonym: synovial plicae of the knee. Common cause of anterior knee pain typically present with pain on anteromedial aspect of the knee above the joint line associated with crepitation, catching and locking sensations.  Typically involves young with athletic background.  There are actually synovial invaginations as a part of remnants of embryological development. They are present in over 70% of individuals and are mostly asymptomatic. However can become inflamed and symptomatic. They can undergo fibrosis secondary to repeate d inflammation making them non-stretchable. In symptomatic patients, medial plica seen as low signal intensity band on T1 as well as T2-weighted images with an associated chondral defect involving medial articulating facet of patella. Treatment is mainly conservative, physiotherapy and steroid injections. View on the web Inoreader. Take back control of your news feed. Follow us on Twitter and Facebook.

Osteochondrosis of Superior Pole of Patella

xlomafota13 shared this article with you from Inoreader Osteochondrosis of Superior Pole of Patella Via Neuroradiology Cases Clinically young male patient with athletic background complaining of typical unilateral anterior knee pain. Marked tenderness at the superior pole of patella. This MRI study of knee joint shows abnormal irregularity, fragmentation with sclerosis involving superior pole of patella with thickening of quadriceps tendon. Associated knee joint effusion. Imaging findings consistent with osteochondrosis of patella at superior pole. Osteochondrosis of the superior pole of the patella Osteochondroses are a heterogeneous group of injuries to the epiphyses and apophyses of children or adolescents, are actually osteonecrosis repetitive microtrauma and avulsion injuries. Imagingwise characterized by bone fragmentation and sclerosis. There are two well-known such syndromes associated with knee joint one is Osgood-Schlatter disease, an avulsion of the tibial tuberosity and another is Sinding-Larsen-Johansson disease, a chronic avulsion injury of the lower pole of the patella at the insertion of patellar t endon. The less well described osteochondrosis at the superior pole of patella appears secondary to similar mechanism associated with quadriceps tendon insertion, a rare cause of anterior knee pain in children between 5 and 9 years of age, usually affects the single knee but bilateral cases have also been reported.

Morel-Lavallée lesion MRI

xlomafota13 shared this article with you from Inoreader Morel-Lavallée lesion MRI Via Neuroradiology Cases Clinically RTA, run over by tractor. This MRI study shows a focal well defined lentiform shaped subcutaneous collection on medial aspect of knee joint superficial to the superficial fascia. Collection is clear, hypo intense on T1-weighted images without any septation or loculation. No obvious high signal intensity methaemoglobin staining on T1-weighted images to suggest any haematoma. Morel-Lavallée lesion These are focal well defined lentiform shaped subcutaneous serous collections commonly encountered during MRI knee joint in the setting of severe trauma. However these lesions are typically described in thigh as well defined collection overlying the greater trochanter of the femur, tensor facia lata.  These actually localized haemolymphatic collections secondary to closed degloving injuries, where the skin and subcutaneous fatty tissue abruptly separate from the underlying fascia owing to trauma. The potential space thus created superficial to the superficial fascia is filled by serous fluid, some times frank blood. Similar collection secondary to similar biomechanical forces are described in lumbar region and over the scapula as well.  The accumulated collection usually needs nothing to be done, resolves spontaneously. However may persist longer if gets organized and encapsulated. The conservative management is with compression bandages. Surgical drainage may be sufficient for larger collection. However, the capsule may need to be resected to prevent re-accumulation if it is long standing and encapsulated collection with thick organized wall.  View on the web Inoreader.

The C-S Approach for The Management of Median or Paramedian Frontal Sinus Lesion

xlomafota13 shared this article with you from Inoreader The C-S Approach for The Management of Median or Paramedian Frontal Sinus Lesion Via Otolaryngology Indian Abstract The frontal sinus is one the most complex of the paranasal sinuses, its proximity to the cranial vault and the orbit cause that frontal sinus pathologies can progress to involve these structures and lead to significant morbidity, or even death. Surgical management of the frontal sinus is technically challenging, the most commonly used surgical approaches are coronal, butterfly, gullwing and suprabrow. The purpose of this article is to propose the C-S approach, an interesting alternative to the gullwing approach for the managing of median and paramedian frontal sinus lesions or isolated displaced fractures of the anterior wall. The main advantage of this technique is represented by the fact that it follows the new tension lines described in the literature, a curved vertical line that follows the glabellar frown.

Impact of Depth of Invasion (According to Layer) on Lymph Node Metastasis in Buccal Mucosa Cancers

xlomafota13 shared this article with you from Inoreader Impact of Depth of Invasion (According to Layer) on Lymph Node Metastasis in Buccal Mucosa Cancers Via Otolaryngology Indian Abstract (1) To study layer of invasion as predictor of cervical lymph node metastasis. (2) To decide a cut off depth according to layer of invasion for neck dissection. It is a prospective study with sample size of 220 patients at tertiary care hospital with previously untreated operable buccal mucosa carcinoma over period of 21 months. The factors considered under the study were Tumor layer of invasion, lymph node metastasis, Ultrasonography doppler neck, CT scan and gender. Wide excision of the lesion and reconstruction was done. Histopathological analysis of resected specimen were recorded as part of data collection for all the cases. Quantitative data represented using Mean ± SD (Standard Deviation) and median and interquartile range compared using Chi square test. Standard principles of univariate analysis was used according to statistical methods. Depth when measured according to layer of invasion, was significantly associated with lymph no de metastasis with 89% of the muscle as layer of invasion being Lymph node positive (p = 0.009). There is 1.39 times chances of lymph nodal metastasis in patients with muscle invasion as compared to submucosal invasion. Tumour layer of invasion plays important role in predicting chances of nodal metastasis in clinically N0 neck in buccal mucosa cancer. According to the study, we should electively proceed with ipsilateral lymph node dissection once the layer of tumour invasion is muscle. This study is limited by sample size and short duration of one year and nine months. View on the web Inoreader. Take back control of your news feed. Follow us on Twitter and Facebook.

The effect of short radiation treatment breaks on chemo‐radiotherapy for oropharyngeal cancers

xlomafota13 shared this article with you from Inoreader The effect of short radiation treatment breaks on chemo‐radiotherapy for oropharyngeal cancers Via Head & Neck Abstract Background Numerous studies and guidelines suggest an outcome detriment from radiation treatment breaks (rTBs) and the need for compensatory dosing in patients with head and neck cancer. Methods In a consecutive cohort of 521 patients with oropharyngeal squamous cell carcinoma (OPSCC), we investigated the impact of rTBs and prolongation of overall treatment time (OTT) on OS, DFS, LRC, and cancer recurrence using competing risk and multivariate analyses. Results Neither OTT prolongation by ≤2 days nor rTBs of ≤3 days were associated with detriments to clinical outcomes. Consecutive breaks of ≥3 days were also not significantly associated with detriment to clinical outcomes. There was significantly increased competing mortality in those with longer breaks. Conclusions In OPSCC patients treated with definitive concurrent chemoradiotherapy, there is no significant association between disease failure and total rTBs of ≤3 consecutive or scattered days. Further investigation is needed for longer breaks. View on the web Inoreader. Take back control of your news feed. Follow us on Twitter and Facebook.
