Discoid meniscus is the commonest anatomical aberration of the knee joint, among rare cases such as bilateral separated lateral meniscus, accessory lateral meniscus, partial deficiency of the lateral meniscus and double-layered lateral meniscus. An 11-year-old girl presented with history of chronic pain in her right knee for the last 6 months. The problem disturbed her involvement in the sport activities at school. Clinical examination revealed a clicking sensation on knee extension with lateral joint line tenderness. Magnetic resonance imaging (MRI) of her right knee showed torn posterior horn of lateral meniscus. Arthroscopy examination revealed a discoid meniscus with absence posterior horn. Posterior horn deficient discoid meniscus is a rare form of a congenital meniscus anomaly. We as clinicians believe that the abnormal shaped meniscus may pose a diagnostic challenge clinically and radiologically. Presentation of this case may be beneficial for orthopaedicians in their daily clinical practice.
Tibia vara and slipped upper femoral epiphysis (SUFE) share a common risk factor, but their relationship is unclear. In both conditions, the patients are usually obese. To the best of our knowledge, there have been only two previous reports in the literature that have described the occurrence of tibia vara and SUFE in three patients. We report a child who was treated for bilateral tibia vara at the age of 3 years and subsequently developed a SUFE at the age of 13 years.
The causes of groin pain after total hip arthroplasty are numerous, and the condition itself is disabling. Therefore, it is imperative that the cause of the pain is identified and managed appropriately. We report a case where the patient had groin pain after total hip arthroplasty as a result of an oversized cementless acetabular component, which caused a breach in the anterior wall of the acetabulum. The anterior wall of the acetabulum was reconstructed with femoral head allograft, and the patient has been symptom free since.
The aim was to compare the effectiveness of intra-articular lidocaine (IAL) versus intravenous Demerol and Diazepam (IVS) in reduction of acute anterior shoulder dislocation.
Anti-nuclear antibody (ANA) negative systemic lupus erythematosus (SLE) occurs in about 4-13% of SLE cases. A small group of ANA negative SLE patients with positive anti-Ro antibodies usually present with typical vasculitic skin lesions which can be associated with photosensitivity, renal disease, congenital heart block or neonatal lupus. We present a case of a persistently ANA negative patient who presented with joint pain, rashes, mouth ulcer and alopecia. Clinical diagnosis of systemic lupus erythematosus was made even though ANA was negative. She was started on steroids and went into remission. Later, she developed several episodes of convulsions associated with fever and prominent vasculitic lesions. The patient was also found to have microscopic hematuria, proteinuria, anemia and thrombocytopenia. Renal biopsy showed lupus nephritis class 1B. Due to the prominent skin lesions, we performed anti-extractable nuclear antigens (ENA) antibodies test and anti-Ro turned out to be positive. The final diagnosis was ANA negative SLE (Ro lupus) with cutaneous, renal, musculoskeletal, hematological and cerebral Involvement.
Pyrexia of unknown origin (PUO) is a frequent presentation to the Acute Medical Unit, and is a source of significant morbidity, both the psychological burden of an uncertain diagnosis and prognosis and untreated complications of the underlying pathology. We present a problem based review of the management of PUO, illustrated by a patient who recently presented to our unit with fever and systemic malaise after returning from abroad and in whom no cause could be found for more than two months. We describe a structured approach making use of complex modern techniques such as Positron Emission Tomography-Computed Tomography (PET-CT) which ultimately provided the diagnosis for our patient.
