radiocarpal joint consists of eight carpalbonesof which one is the hamate . When a break of serve occurs in this little bone present in articulatio radiocarpea , it is known as hamate fracture .
The eight carpal bone of thewristare situate between the clappers of the forearm experience as ulna and radius and the pearl present in the handwriting . Hamate is a bone , which is locate on the outside or the piddling fingerbreadth side of the wrist and has a hook shaped construction at the end . The claw shaped part of the hamate bone which protrudes outwards may break easily due to accidental injury . This condition is known as fracture of come-on of hamate .
Stress or compression[1]could be placed on the hook of hamate os while performing mutation bodily process like racket sport or fall down on an outstretched hand . If the force is traumatic and beyond the tolerance power of the bone then this may lead in geological fault of the hook of unciform bone .
Causes of Fracture of Hook of Hamate
Signs and Symptoms of Fracture of Hook of Hamate[2]
Treatment for Fracture of Hook of Hamate[3]
In eccentric where there is just a minor fracture or deviation of the pearl from its normal alignment , it may be corrected with handling and reduction . Conservative care involves shut step-down under local anesthesia followed by casting or splint of hand . Fracture may involve about six to ten weeks for complete recovery , which involve a period of immobilization for about four to six hebdomad followed by protective splinting for about six week .
Surgeryis needed in individual who have deformity that is not able to be treat nonsurgically . This method is call open reduction .
operative procedure is done by get incision to expose fracture and then get it back into plaza . This in some grammatical case requires use of pins , screws , etc .
In cases where the fault of hook of os hamatum blend unnoticed for a good amount of fourth dimension then it is probable that the fracture may not cure . In such display case , the good alternative may be to transfer the pearl fragment completely .
The risks of OR are run , neurovascular injury , infectionetc .
Physical Therapy : PT is necessary to promote healing and normal role of wrist andhand . It may consist of :
Exercises for Fracture of Hook of Hamate
Stretching and strengthening exercises may demand to be performed during the recovery phase to gain complete range of motion and functionality of the radiocarpal joint .
Stretching Exercises for Fracture of Hook of Hamate
Flexion : To perform this employment , the radiocarpal joint is bent forward until a painless stretchability is sense . It can be done for five seconds and execute in two sets of 12 each .
Extension : To perform this workout , the wrist joint is dead set rearwards until a painless stretch is sensed . It can be done for five seconds and performed in two sets of 12 each .
Side - to - Side : The wrist is bent sideways till it is painless for about four seconds in one direction and then the other and is performed in two sets with 15 times in each set .
Wrist Extension Stretching : This can be done by having the elbow flat and placingfingerson an objective with thenar looking down . Then , the bodyweight is put forward and the position is hold for about 20 minute .
Wrist Flexion Stretching : It can be done by keeping articulatio cubiti directly and placing fingers two-dimensional on an aim with palms in the upward focal point . Then the bodyweight is put forward and the place is hold for about 20 seconds .
Pronation and Supination of Forearm : In this exercise , the elbow is bent at a proper angle . The medal is then circumvolve up and it done for about 10 seconds . Now , the same thing is done in the paired way for 10 seconds . It should be done thrice with 10 times each without exacerbate symptoms .

One can take over as long as there is no aggravation of symptom ..
Resistance Band Radial Deviation : In this practice , a ohmic resistance is place over finger with thumb facing upwards . The elbow is kept at side of body and is bent at a right angle with the support of the other deal . The next affair to do is to slowly curl wrist upwards abut the resistance so as to make the muscularity of forearm tight . One can repeat as long as there is no exacerbation of symptom .
Investigations for Fracture of the Hook of Hamate[4]
A complete test is carried out to corroborate fault of the lure of hamate . A neurovascular scrutiny is also done of the hands to await for injuries to nerves and vessels . An x - ray may also be done to find out the severity .
