Paper text:
distal median nerve masses may be developed post - traumatic or non - traumatic . in this paper , we aim to present a 52 year old female case with a postraumatic neuroma of the median nerve in the left wrist .
a 52-year - old female patient had accidental incised wound over her left wrist which was primarily sutured .
intraoperatively the mass was seen to arise from medial nerve and careful excision was done protecting the nerve . at one year follow up the patient is relived of her symptoms with no sensorimotor deficit .
post traumatic neuroma present as unrelieved pain and progressive swelling . a high index of suspicion
should be kept in cases of wound that are primarily sutured over an area with superficial nerves .
soft tissue , skin or bone tumors should be considered in the differential diagnosis of the hand tumors .
neuromas are the most common solid peripheral nerve tumor frequently seen in 30 - 60 ages .
neuromas can originate after trauma to the nerves and such cases are rarely reported in literature [ 4 - 6 ] . in this paper , we aim to present a case with post - traumatic neuroma of the median nerve on the left wrist diagnosed by usg - clinical findings and confirmed with pathological reports .
a 52-year - old female had accidental incised wound over her left wrist which was primarily sutured elsewhere .
she was reffered to our centre 6 months after injury with unrelieved wrist pain and progressively growing mass on the wrist .
usg showed a solid tumor of size 2 x 3 cms and a decision for excision of the mass was taken .
local anaesthesia was given over the area and skin and subcutaneous tissues were dissected to isolate the tumor .
the tumor was carefully excised from the surrounding tissue trying to keep the nerve intact .
intraoperative examination was possible as patient was under local anesthesia and minimal motor disability and hypoesthesia were noted ( fig .
histopathological examinations revealed wallerian degeneration in evolutionary phase as revealed by disorganized growth in axonal and perineural structures ( fig 4 ) .
the patient had a normal outcome with no pathological findings after one year follow - up median nerve neurinomma pathological findings
hand injuries must be carefully examined because of anatomic and neurovascular complexity of hand and wrist .
sharp devices , gunshot injuries , occupational injuries and traffic accidents are the most common causes of hand injuries[7 - 9 ] in a study , seddon divided nerve fascicle injuries into three types ; noropraxia , aksonothemesis and norothemises .
it is stated in this study that noropraxia , does not need any surgical treatment , wallerian degeneration does not occur and the injury can recover completely . in axonothemesis , axonal integrity can be broken but endoneural tubes remain contact .
motor , sensorial and otonomic disfunctions can be present with complete wallerian degeneration . in norothemesis , when the nerve is completely disfonctioned , internal anatomy of the nerve can also be damaged and motor , sensorial and otonomic disfunctions at the distal region of the injury become significantly present .
clinical and electroneuromyographical ( enmg ) study results can be the same with axonothemesis . when the nerves are partially or completely damaged after injury , axonal regeneration initiated by proximal part of the nerve is mostly resulted as neuroma . in adults ,
mean regeneration rate is 1 - 2 mm / day . if fibrous barrier has been developed in injury site , than the axons can not be able to find enough room to grow up and form a mass with fibrous tissue which is called neuroma .
there are some articles about post - taumatic or non - traumatic median nerve masses in the literature . in 1969 ,
a two cm sized neuroma occured after distal radius fracture and trapped in fracture line was disgussed . after having median nerve excision for neuroma
, nerve ends were sutured and the patients showed remarkable improvement in the four - mounth follow - up .
in the recent studies ; chen et al . reported a 42-year - old female cut the wrist in a suicide attempt and had subsequent tendon and median nerve repairment followed by rehabilitation .
after neuroma on the median nerve region was confirmed by the excision of the lesion in the surgery , nerve repairment with a nerve graft was performed and the patient 's symptoms improved significantly .
reported that distal traumatic median nerve neuromas are mostly painful and related with recurrent carpal tunnel syndrome which is generally managed with hypothenar fat pad flap .
hubert et al .   reported a schwannoma sized 4.0x0.5x1.2 cm and located in carpal tunnel .
bagatur and yalinkaya   reported two giant lipomas in carpal tunnel . in a study of zdemir
et al . , 10 of 14 patients had tumours located in the median nerve distribution area , whereas 4 were found on the ulnar nerve distribution .
four tumours were at the wrist level , 3 at the palm level , and 7 at the digital level .
our case was a post - traumatic neuroma of the median nerve on the left wrist and the diagnose was confirmed by clinical , ultrasonographical and electrodiagnostic examinations .
after one - year follow - up , the patient had normal clinical findings without any pain or neuromotor loss .
in addition , opposition loss is frequently present in distal level median nerve injuries . however , in our case , the patient had complete nerve injury with no opposition loss or any motor deficits .
in conclusion , the masses on the wrists and hands are not rare and can be seen as posttraumatic or non - traumatic .
however , trauma related soft - tissue masses on the wrist have usually been reported as case reports in the literature . therefore , hand injuries , must be carefully inspected by experienced orthopedic surgeons because of anatomic and neurovascular complexity of hand and all possible outcomes should be considered in the management of these cases .
incised wounds over nerves should be carefully inspected for nerve injuries and primary suturing of such wounds can lead to post traumatic neuromas .
these neuromas are cause of pain and discomfort , however they can be easily treated by excision of the lesion
introduction : distal median nerve masses may be developed post - traumatic or non - traumatic . in this paper , we aim to present a 52 year old female case with a postraumatic neuroma of the median nerve in the left wrist.case series : a 52-year - old female patient had accidental incised wound over her left wrist which was primarily sutured . 
 she presented 6 months later with unrelieved pain and growing swelling at the wrist . 
 usg showed solid mass of size 2x3 cms . 
 intraoperatively the mass was seen to arise from medial nerve and careful excision was done protecting the nerve . at one year follow up the patient is relived of her symptoms with no sensorimotor deficit.conclusion:post traumatic neuroma present as unrelieved pain and progressive swelling . 
 a high index of suspicion should be kept in cases of wound that are primarily sutured over an area with superficial nerves . 
 careful excision of the lesion is very effective in relieving patients symptoms
