Recurrent intra-articular osteoid osteoma of the hip after radiofrequency ablation: a case report and review of the literature

We present a case of a 53-year-old woman with recurrent intra-articular osteoid osteoma of the hip 6 months after initial treatment with percutaneous radiofrequency ablation. En bloc surgical excision of the osteoid osteoma and prophylactic internal fixation for impending stress fracture was performed. The patient is pain free, has returned to normal function and there is no sign of recurrence at the one-year follow-up. Intraarticular osteoid osteoma, present a diagnostic challenge and often they are misdiagnosed. Minimally invasive ablation techniques can fail in significant percentage and then surgical excision with histological confirmation remains the definitive treatment of choice

Diagoras of Cyprus (3rd century BC) – an eminent oculist and opposer to the use of opium

The objective of this article is to showcase the use of opium in ancient times, as well as the beliefs surrounding it, focusing on the opinion of Diagoras of Cyprus, a physician with great knowledge of pharmacology who probably practiced ophthalmology, composing a rose-based collyrium. Opium, a drug produced from poppy, used to have several uses such as in anesthesia, pain relief and ritualistic purposes. There is evidence of its creation since before 5000BC. In Greece, the first documentation dates back to around 2600-1100 BC in Crete. Many ancient medico-philosophers used to utilize it in their practice, mentioning it in the majority of the medical texts of that time. However, there were others that disapproved of its use due to the possible side effects. Diagoras was one of them, as he categorized opium as a lethal substance that could cause severe problems to the vision. He may even have thought of the possible addiction that it can cause because of the euphoric state it puts a person in. Some practitioners mentioned Diagoras’s opinion on opium, such as Erasistratus and Pliny the Elder. Despite his contributions in opium usage and ophthalmology, Diagoras is still unappreciated as a medical figure

The anatomy of the medial collateral ligament of the knee and its significance in joint stability

The medial collateral ligament (MCL) is the most important stabilizer of the medial side of the knee together with the capsuloligamentous complex. As such, it has a distinctive role in joint stability, as far as its biomechanics are concerned, and major joint stability issues onset when it is injured or deficient. One of the main functions of the medial collateral ligament is mechanical as it passively stabilizes the knee and help in guiding it through its normal range of motion when a tensile load is applied. It exhibits nonlinear anisotropic mechanical behaviour, like all ligaments, and under low loading conditions it is relatively compliant, perhaps due to recruitment of “crimped” collagen fibres as well as to viscoelastic behaviours and interactions of collagen and other matrix materials. Continued ligament-loading results in increasing stiffness until a stage is reached where it exhibits nearly linear stiffness and beyond this it continues to absorb energy until it is disrupted. In addition, the function of the MCL has to do with its viscoelasticity which assists the maintainance of joint congruity and homeostasis. The treatment of grade III medial collateral ligament injuries (with gross valgus instability at 0° of flexion) is still controversial. The most severe injuries (especially with severe valgus alignment, intra-articular medial collateral ligament entrapment, large bony avulsions, or multiple ligament involvement) may require acute operative repair or augmentation. In addition, surgical reconstruction is indicated for isolated symptomatic chronic medial collateral ligament laxity. The optimal surgical treatment remains controversial. More studies with evidence of level I and II are required in order to clarify the pros and cons of any solution

Cervical myelopathy from calcium pyrophosphate dihydrate crystal deposition: a case report

Calcification of the ligamentum flavum secondary to calcium pyrophosphate dihydrate (CPPD) deposition may be a rare cause of cervical myelopathy. We present a 56-year-old man with spinal stenosis secondary to CPPD disease and subacute cervical myelopathy following minor trauma. The patient had no history of CPPD disease. Posterior C4-C6 decompression and instrumented fusion were performed. Intraoperative findings were densely thickened ligamentum flavum and distortion of the cervical dura mater due to impingement. Histological sections of discs and ligamentum flavum specimens showed CPPD crystals. Postoperatively, neck pain and paresthesias improved immediately. At 2 weeks after spinal surgery, the patient experienced acute right knee swelling. Standard radiographs showed chondrocalcinosis of the knee menisci

It is time to reconsider the classification of dens fractures: an anatomical approach

A clinical study was performed to evaluate a new classification for odontoid process fractures. The external and internal anatomy of the axis has been studied. The files of 97 patients with a fracture of the odontoid process admitted to our institution were reviewed and classified according to the proposed new classification. The method was tested for reliability and validity. The patients were followed for a mean period of 14 years, in order to evaluate the outcome of these fractures and to correlate it to the fracture type. Intraobserver and interobserver agreement was excellent with intraclass correlation coefficients at levels of 0.98 and 0.85, respectively. Four types of odontoid process fractures are distinguished. Type B fractures are associated with high risk of pseudarthrosis. Existing classifications are inadequate and misleading since they do not include all types of odontoid process fractures, nor they consider the internal anatomy of the odontoid process. Classification of the odontoid process fractures has to be reconsidered as novel-imaging technology has shown new patterns of fractures. The analysis of the imaging data in the present study justifies the new classification
