Lipomas are common benign neoplasms consisting of mature fatty tissue. They are usually of roundish or ovoid shape and are situated in a single anatomical region. They most frequently occur on the back and in the extremities. Most lipomas are subcutaneous and require no imaging evaluation. When deep, large and unusual in location, MRI can identify and localise these tumours and is the best exploration to differentiate lipoma and lipo-sarcoma. We describe a case of a patient with an intramuscular lipoma of the biceps brachii.

We treated a patient with a rare combination of ipsilateral fractures of the distal and proximal ends of the radius. A man aged 42 years had simultaneous fractures of the distal and proximal ends of the radius (radial neck) following a roadside accident. The distal end fracture of the radius was treated with surgical reduction and T-plate volar fixation, and the undisplaced radial neck fracture was treated by an above elbow splintage for 2 weeks. The elbow mobilization was started at 2 weeks. The distal radius was protected for another 4 weeks in a below elbow functional brace. Ipsilateral proximal and distal radial fracture is an uncommon injury pattern. The series illustrates a number of problems associated with this combination. Firstly, one should be aware of this rare injury pattern and there should be greater emphasis on clinical examination of elbow in cases of wrist injuries and vice versa. Once diagnosed, one faces the dilemma of appropriate management in these cases. The appropriate management will depend on the injury characteristics including the age of the patient and the fracture pattern. One should try to preserve the radial head to prevent a possible proximal radial migration especially in younger patients.

We report a case of mucoid degeneration of the anterior cruciate ligament (ACL). Mucoid degeneration of the ACL is a very rare cause of knee pain. There have been only some reported cases of mucoid degeneration of the ACL in the English literature. We reviewed previous reports and summarized clinical features and symptoms, including those found in our case. Magnetic Resonance Imaging is the most useful tool for differentiating mucoid degeneration of the ACL from an intraligamentous ganglion or other lesions in the knee joint. If this disease is considered preoperatively, it can be diagnosed easily based on characteristic findings.

Isolated palmar dislocation of the fifth carpometacarpal joint is an uncommon injury and classified as radio-palmar or ulno-palmar according to the direction of displacement of the fifth metacarpal base. This very rare injury is often difficult to recognize. A careful neurologic assessment of the patient is a necessity, as well as obtaining proper radiographs of the hand. The purpose of this report is to present a patient with a pure isolated volar dislocation of the fifth carpometacarpal joint that was satisfactorily treated with closed reduction and casting. A review of the literature is presented.
