A medical kit of instruments for transplanting a section of a first bone to a second bone in an arthroscopic procedure comprising: (a) a bone drill for drilling a first bore and a second bore in the section; (b) an arthroscopic drill guide for guiding drilling of the second bore a predetermined distance from a first bore formed in said section, comprising: a handle; an elongated shaft comprising a proximal end and a distal end, said proximal end coupled to said handle, said shaft configured to receive said bone drill; a drill nut at a distal portion of said drill guide, said drill nut defining an axis of said bone drill; and a guide pin positioned at a fixed predetermined distance (d) from said axis of said bone drill; said guide pin configured to fit within said first bore formed in said section; and (c) a double cannula including: two tubes (t) extending parallel to each other; and a proximal end carrying a handle (h), wherein said two tubes have axes at said predetermined distance (d) allowing co-axial positioning of a first of the two tubes with said first bore when a second of the two tubes is coaxially aligned to said second bore for attaching said section to said second bone through said first bore and said second bore; and wherein each of said two tubes (t) has a distal end formed with a window (w) to enable observation of its interior. (a) a bone drill for drilling a first bore and a second bore in the section; (b) an arthroscopic drill guide for guiding drilling of the second bore a predetermined distance from a first bore formed in said section, comprising: a handle; an elongated shaft comprising a proximal end and a distal end, said proximal end coupled to said handle, said shaft configured to receive said bone drill; a drill nut at a distal portion of said drill guide, said drill nut defining an axis of said bone drill; and a guide pin positioned at a fixed predetermined distance (d) from said axis of said bone drill; said guide pin configured to fit within said first bore formed in said section; and a handle; an elongated shaft comprising a proximal end and a distal end, said proximal end coupled to said handle, said shaft configured to receive said bone drill; a drill nut at a distal portion of said drill guide, said drill nut defining an axis of said bone drill; and a guide pin positioned at a fixed predetermined distance (d) from said axis of said bone drill; said guide pin configured to fit within said first bore formed in said section; and (c) a double cannula including: two tubes (t) extending parallel to each other; and a proximal end carrying a handle (h), wherein said two tubes have axes at said predetermined distance (d) allowing co-axial positioning of a first of the two tubes with said first bore when a second of the two tubes is coaxially aligned to said second bore for attaching said section to said second bone through said first bore and said second bore; and wherein each of said two tubes (t) has a distal end formed with a window (w) to enable observation of its interior. two tubes (t) extending parallel to each other; and a proximal end carrying a handle (h), wherein said two tubes have axes at said predetermined distance (d) allowing co-axial positioning of a first of the two tubes with said first bore when a second of the two tubes is coaxially aligned to said second bore for attaching said section to said second bone through said first bore and said second bore; and wherein each of said two tubes (t) has a distal end formed with a window (w) to enable observation of its interior.
