Anterior cruciate ligament (ACL) reconstruction with autogenous semitendinosus and gracilis tendons has become a common surgical procedure. Lower leg paresthesia following injury to the infrapatellar nerve during harvesting of the tendons has been well documented. Few authors have described the position of the infrapatellar nerve on a flexed knee, which is the position used during ACL reconstruction. The purpose of this study was to determine a safe area and angle where an incision could be made for harvesting of the semitendinosus and gracilis tendons, with the knee in flexion. Twenty right cadaver knees and 20 left knees were dissected. Landmarks on the knee were identified, from where the distances to the nerves (infrapatellar and saphenous) were measured with a vernier caliper. A safe area on the right knee was determined to be on the tibial tuberosity plane between 3.7 and 5.5 cm with a safe angle of incision of 51.6 degrees. A safe area on the left knee was determined to be on the tibial tuberosity plane between 3.6 and 4.9 cm with a safe angle of incision of 52.5 degrees. The results may assist orthopedic surgeons performing ACL reconstruction with semitendinosus and gracilis tendons to avoid cutaneous nerve damage and, therefore, patient discomfort.

In children with right lung volume loss from TB, the compression of the contralateral bronchus is due to narrowing of the pulmonary artery bifurcation angle as the main trunk rotates towards the midline. This is comparable to the post-pneumonectomy syndrome.

Ankylosing spondylitis is a debilitating disease that is one of the seronegative spondylarthropathies, affecting more males than females in the proportion of about 6:1 in the age group 15 - 35 years of age. Early radiographic findings include bilateral sacro-iliitis and early axial (lower lumbar spine) ankylosis. Typical X-ray findings are florid spondylitis (Romanus lesions), florid diskitis (Andersson lesions), early axial ankylosis, enthesitis, syndesmophytes and insufficiency fractures. Typical radiological abnormalities are pointed out on conventional X-rays and reviewed for early diagnosis and prompt treatment of patients at risk.

Chronic pulmonary tuberculosis may present as massive haemoptysis. Haemoptysis usually originates from the bronchial artery but the pulmonary artery might be the culprit vessel in recurrent haemoptysis. We present a case where bronchial artery embolisation had to be augmented by pulmonary artery coil embolisation for a Rasmussen's aneurysm after recurrent haemoptysis. In cases where recurrent haemorrhage occurs, sources other than the bronchial artery should be considered.
