Preventing post-traumatic osteoarthritis is a challenging problem following acetabular fracture. Progressive osteoarthritis is considered to be caused by an irregular articular surface of the acetabular roof or cartilage injury, but little is known about the pathogenesis of collapse of the femoral head after acetabular fracture. We report a case of post-traumatic osteoarthritis after acetabular fracture in which subchondral fracture of the femoral head contributed to the progressive collapse of the femoral head and osteoarthritis. To the best of our knowledge, there has been no previous report of subchondral fracture of the femoral head after acetabular fracture. ⋯ Our experience with this case indicates that in addition to post-traumatic osteonecrosis, subchondral fracture may need to be considered in cases with progressive collapse of the femoral head after acetabular fracture.

Cranial nerve palsy is a common presentation in the neuro-ophthalmology clinic and investigations are directed towards the cause. Metastatic breast cancer presenting as carcinomatous meningitis leading to sequential fourth, third and sixth nerve palsy is very rare. This is the first case to be reported to the best of our knowledge. ⋯ Metastatic cancer may manifest as cerebral metastases or carcinomatous meningitis. This is evident on neuroimaging with contrast and may be missed on unenhanced scans.

Nicolau syndrome, also known as livedo-like dermatitis or embolia cutis medicamentosa, is a rare complication following the intramuscular or intra-articular injection of various drugs. ⋯ Although Nicolau syndrome develops very rarely, it is an important cause for morbidity. It is an iatrogenic condition, treated mostly by health care workers. Thus, although it appears to be a very simple procedure for a health care worker, care must be taken during intramuscular injections. Although diclofenac sodium is a widely used non-steroidal anti-inflammatory drug, Nicolau syndrome following intramuscular diclofenac sodium injection has rarely been reported in the published literature. The application of a cold compress was considered to be an aggravating factor in our patient. This case highlights the need for awareness about this condition and the need to exercise utmost care during the administration of any parenteral injections by health workers.

Shoulder dislocations can cause acute and chronic instabilities that need to be addressed in order to restore joint functioning. The transfer of the coracoid process has become a feasible surgical procedure in patients with shoulder instability. Several concomitant injuries after recurrent dislocations have been described. ⋯ Patients suffering from anterior shoulder dislocation might develop accompanying lesions after numerous dislocations that are not present upon first visit. Different techniques for the reconstruction of the glenoid rim and the restoration of shoulder joint stability have been described in the literature. We opted for a coracoid transfer and achieved an optimal reconstruction, as shown on the postoperative computed tomography scan. An avulsion fracture of the coracoid process with dislocation of the conjoined tendons can not only be found in patients suffering a direct trauma as pointed out in the literature, but also in patients with anterior shoulder instability with recurrent anterior shoulder dislocation.

It has been well documented that labral tear is frequently associated with femoroacetabular impingement and dysplasia of the hip; however, there have been few reported cases of labral tear associated with idiopathic osteonecrosis of the hip. Here we report the case of a patient with labral tear associated with idiopathic osteonecrosis of the femoral head who was treated by hip arthroscopy, with a favorable short-term outcome. ⋯ The case indicated that it is important to be aware of the possibility of labral tear in patients with idiopathic osteonecrosis of the femoral head, when spreading of the osteonecrosis area or collapse of the femoral head has not been seen on magnetic resonance imaging.
