Preliminary image findings of lower limb stress fractures to aid ultrasonographic diagnoses: A systematic review and narrative synthesis

Introduction This systematic review investigates which image appearances are most common when diagnosing lower limb stress fractures using ultrasound imaging, with the aim of outlining an image critique guideline for operators to support confident diagnoses. Method A comprehensive literature search of medical databases and handsearching was undertaken to identify relevant studies. All studies were critically examined for quality using the CASP critical appraisal tool. Results from eight studies were combined and interpreted using a narrative synthesis. Findings A clear outline of common stress fracture appearances using ultrasound were identified in a combined total of 119 participants. Each finding was ranked according to its popularity. Periosteal thickening (78/119) and cortical disruption/irregularity (83/119) were noted in all eight studies. Hypervascularity of the periosteum visualised by colour Doppler imaging (66/119) was reported in six of the eight studies. Soft tissue hypervascularity (13/119), bony callus formation (5/119) and cortical break (22/119) were seen in three studies. Conclusions Based on the findings, we offer a guideline of the most significant preliminary image findings to be utilised by operators when examining athletes suspected of having lower limb stress fractures. The results show a gap in research for evaluating changes in appearance depending on the injury severity. Further research into distinguishing stress fractures from pathological involvement may in future reduce reliance on plain film radiography.

76 This is (Probably) Not the Frailty Solution You are Looking For: Utilisation of A Novel Stand-Alone Community-Based Ambulatory Care Unit

Introduction/Aim Our organisation wished to expand its “Care Closer To Home” capability, especially for older and/or frail patients. Our novel Ambulatory Care Unit (ACU) in a community hospital, staffed by GPs & nurses, opened a year ago. The ACU has some Point of Care (POCT) diagnostics, access to plain-film radiography and OT/physio. During the planning of the unit,” acute frailty” was anticipated to be core business. We wished to determine whether this turned out to be the case. Method Interrogation of the ACU patient log (spreadsheet collated from Data Collection Forms) Dec 2018-Nov 2019. Results Conclusion/Discussion Recording of CFS by ACU staff was poor, limiting the validity of our results. Nevertheless, it is obvious that most patients seen in our ACU are not frail, and do not require therapies input. Those that are frail, however, have an acceptable conversion-to-admission rate of 8.6%, comfortably below the national target (20%). Barriers to greater utilisation of our service for frail patients may include lack of urgent but non-emergency transport options for the less mobile, lack of access to certain commonly-used tests (e.g. CT, troponin) and referrer anticipation of difficulty discharging the frail patient in crisis without a new or boosted care package and/or access to respite beds. These aspects of service planning need to be addressed if the potential utility of community-based units like ours for frail patients is to be maximised.

Limitations of Plain Film Radiography in Identification of Hyperextension Fractures in Patients With Ankylosing Spinal Disorders

Study Design: Efficacy study. Objectives: To elucidate the limitations of radiography in patients with spinal ankylosing disorders (SAD) with an emphasis on thoracolumbar injuries, which have been less focused upon. Methods: We searched our hospital’s emergency room database for patients who underwent a total spine computed tomography (CT) following a diagnosis of SAD on radiographs following a minor fall. A high-quality presentation containing 50 randomly situated anteroposterior + lateral radiographs was created. Of these, 24 contained a hyperextension type fracture diagnosed by CT. Twelve physicians—4 spine surgeons, 4 senior orthopedic residents and 4 junior orthopedic residents were requested to identify the pathologic radiographs and note the fracture level. Results: Fracture diagnosis stood at 65% for the best reader. When examining the different subgroups, the mean rate of diagnosis for spine surgeons was 55% and for orthopedic residents 32%. Mean diagnosis of thoracic fractures was 26%, of lumbar fractures was 55%, and for the entire thoracolumbar spine was 40%. The interobserver agreement (kappa coefficient) was found to be 0.37 for the entire group and 0.39 for spine surgeons. This finding was statistically significant. Conclusions: The simple radiograph is an inefficient modality for diagnosis of hyperextension type thoracolumbar fractures in patients with SAD. The poor interobserver agreement rate further amplifies this finding. Advanced imaging is recommended in these patients.

A case report on the importance of imaging in the diagnosis of Lipofibromatous Hamartoma of the median nerve

This case report presents a lipofibromatous hamartoma of the median nerve in a 31-year-old man who presents local deformity and a sensory deficit in the nerve territory. The tumor was evaluated with magnetic resonance, computed tomography, and plain film radiography, studying the pathognomonic findings of this tumor. The patient did not want surgical treatment because of prior surgical sequelae. A prior surgical biopsy was reported as a peripheral nerve with normal axonal fascicles surrounded by abundant fibroadipose tissue. This tumor has a low incidence with less than 180 cases reported in the literature.

Lower limb acute joint injuries: when to refer for X-ray?

This article summarises the clinical decision tools available to help decide when acute lower limb joint injuries should be referred for plain film radiography. The Ottawa foot and ankle rules are a tool for deciding whether to refer a patient for X-ray or not. The rules are highly sensitive, gaining National Institute for Health and Care Excellence recommendation in the UK, although they have limited benefit in some patient groups, such as those with peripheral neuropathy. The Ottawa knee rules are highly sensitive but less specific than the Pittsburgh decision rules. Although the Pittsburgh rules are more specific, they have been less extensively investigated and, unlike the Ottawa rules, are not National Institute for Health and Care Excellence recommended. A major barrier to use of these rules in clinical practice is the concern of litigation, although National Institute for Health and Care Excellence recommendation should reassure clinicians and thus reduce the amount of unnecessary radiation exposure.

Transoral Approach to Open Reduction of a Traumatic Avulsion Fracture of the Genial Tubercle Associated With a Mandibular Symphysis Fracture: A Case Report and Literature Review

Genial tubercle fracture (GTF) is rare and represents a diagnostic challenge as plain film radiography often fails to identify the fractured segment. Traumatic avulsion of the genial tubercle in conjunction with mandibular symphysis fracture may lead to posterior displacement of the tongue with the potential for airway compromise and difficulty in speech and swallowing due to loss of tongue anterior suspension. Fine cut computed tomography (CT) scan is required to confirm the diagnosis and assist further management. To our knowledge, all published cases of surgical intervention in the management of avulsed genial tubercle combined with fracture of the mandibular symphysis used an extraoral approach via submental skin incision to expose the fractured segment. To the authors’ knowledge, this is the first report to describe a transoral approach in the surgical management of GTF associated with a mandibular fracture.

Neglected Pediatric Osteochondral Fracture Dislocation of the Patella

Pediatric osteochondral fracture dislocation of the patella is sometimes difficult to diagnose on the basis of physical examination or plain film radiography. Magnetic resonance imaging plays an important role in its early diagnosis, and early treatment can prevent damage to the articular cartilage as well as decrease the dislocation rate. Currently, many treatment choices have been reported with good results, but there is no consensus on which treatment option may lead to the best outcome. Herein, we describe the case of a 14-year-old girl with neglected osteochondral fracture dislocation of the patella. The outcome was optimal on the basis of a 2-year postoperative follow-up; thus, we believe that fixation with headless screws is a simple and effective method if the fracture fragment is large enough.
