The script lie of five bones called metacarpal bones for all the five digits . The knuckles at the back of the handwriting are formed by the oddment of the metacarpal bones , which also assist or corroborate the hand . Metacarpal fault happens when one of the long osseous tissue get injure . This could take place by perform sure activity like punch or direct impact to the hand due to which stress is placed on the metacarpal bones . As this kind of stress could be traumatic and beyond what the bone can stand firm , an injury or a break in one or more metacarpals occurs . Thus , the experimental condition is called as metacarpal fault . In other words ; metacarpal fracture can be term as break hand .
Bennett ’s fracture[1]is a condition in which the base of the metacarpal bone gets fractured where it articulates with the os trapezium . Trapezium is one of the eight carpal pearl in the wrist joint that forms a joint at the groundwork of the ovolo screw as first carpometacarpal stick . The joint of the trapezium and pollex metacarpal alkali mould a saddle - like structure that aids importantly in the joints stableness . This joint is covered by liquid cartilage at the closing of the metacarpal bone and os trapezium , which allows well-fixed juncture of the clappers during motion .
Thumb joint is the only articulation in the hand that has the power to move in all directions .
Bennett ’s fracture can be a effect of injuries suffered during most of the inter-group communication play such as fisticuffs , rugby , and soccer .
Causes and Risk Factors of Bennett’s Fracture
Bennett ’s fracture are mostly cause as a outcome of indirect force such as accrue on a quarter round that is jut out out or a nose candy on a clenched clenched fist . Punching is the most common mechanism , which leads to this eccentric of fracture ; however , there are many other reasons such as motor fomite chance event , work relate trauma and falls .
Bennett ’s fracture is a severe case of fault , which if treated inappropriately can extend to lasting disablement with activities , which involve habit of the pollex such as vellicate .

Investigations for Bennett’s Fracture
A comprehensive story and physical test is required for diagnosis of a metacarpal fracture . A thorough examination of the paw and the digit is performed to look for injuries to the nerves or vas . An hug drug - ray is generally required to corroborate the severity . A entreaty view may provide a safe focussed view of the metacarpal joint of the thumb .
