To lead a quality life, tendon repair must be performed in a trauma causing damage to the extensor tendon of the hand. The aim of this study is to study the structures that can be used as donor tendons. Fifty-four dissected adult hands were examined to study the pattern of the extensor tendons on the dorsum of the hand. ⋯ Suitable excessive tendon and the thickest JT as donor tendon were found in the fourth intermetacarpal space. The present findings, especially the fourth intermetacarpal space, may explain why incisions on the dorsum of the hand should be large and performed with particular care. It is necessary to have a thorough understanding of the arrangements of the multiple extensor muscles and their junctural connections of the hand when tenoplasty or tendon transfer is required.

Both Biceps Load tests I and II rely on an increase in tension in the long head of biceps to identify a superior labral anterior and posterior (SLAP) lesion. This study aimed to evaluate the anatomical basis of Biceps Load tests I and II by measuring activity in the long head of biceps in the two clinical tests. ⋯ Activity was only minimally increased in both Biceps Load I and II compared with the resting position. In the absence of convincing support for the anatomical basis of the test, investigations of diagnostic accuracy need to be replicated in order for the reported high accuracy of Biceps Load I and II tests to be supported with confidence.

Laparoscopic adrenalectomy (LA) is the procedure of choice for most adrenal tumors. An important part of LA is the early identification and ligation of the adrenal veins. The venous drainage from each adrenal gland is usually via a single vein: the right vein draining into the inferior vena cava (IVC) and the left vein into the left renal vein. ⋯ Adrenal vein variants were present in patients with phaeochromocytomas (n = 4) or adrenocortical carcinoma (n = 1). The laparoscopic approach allowed an excellent view of the main adrenal venous anatomy. This has helped confirm the constant nature of the venous drainage and successfully identify variant adrenal veins.
