Abstract: An improved miter joint damp is provided in which actuation of workpiece gripping members is effected by a manually actuated member which extends transversely to the plane of the clamp thus facilitating its placement and use.

Abstract: A surgical device primarily useful in arthroscopic acromioplasty surgery, the device, typically a pin, is formed to be temporarily implantable and fixable at a desired depth in one or more locations of the shoulder region. By the proper positioning of one or more of these pins a surgeon can visually identify the various shoulder anatomy, e.g., the acromion, the acromioclavicular joint, the clavicle and the associated ligaments and muscles, to determine the appropriate portion of the acromion to be resected. This allows the surgeon to avoid injuring the various ligments positioned contiguous to the acromior. The surgical device may also be formed with a visually observable measurement scale that can be positioned adjacent to that area of the acromion which is being resected to allow the surgeon to visually determine the extent of the resection.
