Should the thumb metacarpal bone become damaged or misaligned it may be necessary to install a retaining device. Great care and accuracy are needed and should be carried out by a qualified professional only.
When out cold, pull the bone into alignment and clamp firmly in place. It may be possible to shoot retaining wires (2545-11) through the structure without removing the covering layer. However, if any surrounding muscle fibre has been drawn into the break during re-alignment, then it will be necessary to fully dismantle, remove foreign objects and then install a titanium plate (2543-11).
In the latter case, cut down the cover along the bone line and spread with a clean clamp. With the internals re-positioned, drill evenly spaced holes of 1.1mm radially through the undamaged area. Position the titanium plate (2543-11) and fix with 1.5mm titanium screws, without over-torquing. Reassemble and re-join cover with even spaced stiches.
NB: It is advised that a running in period of six weeks is observed. Pressure and sudden movements are to be avoided but frequent controlled exercises will prevent any permanent sticking.
