SUMMARY
Aim: This study was conducted to measure the cross
sectional area (CSA) of the ulnar nerve (UN) in the cubital
tunnel and to evaluate the role of high-resolution
ultrasonography in the diagnosis of ulnar nerve neuropathy
(UNN).
Materials and Methods This was a cross sectional study with
64 arms from 32 patients (34 neuropathic, 30 nonneuropathic).
Diagnosis was confirmed by nerve conduction
study and electromyography. The ulnar nerves were
evaluated with 15MHz small footprint linear array transducer.
The ulnar nerve CSA was measured at three levels with arm
extended: at medial epicondyle (ME), 5cm proximal and 5cm
distal to ME. Results from the neuropathic and nonneuropathic
arms were compared. Independent T-tests and
Pearson correlation tests were used. P value of less than
0.05 was considered significant.
Results: Mean CSA values for the UN at levels 5cm proximal
to ME, ME and 5cm distal to ME were 0.055, 0.109, 0.045 cm2
respectively in the neuropathic group and 0.049, 0.075, 0.042
cm2 respectively in the non-neuropathic group. The CSA of
the UN at the ME level was significantly larger in the
neuropathic group, with p value of 0.005. However, there was
no statistical difference between the groups at 5cm proximal
and distal to the ME, with p values of 0.10 and 0.35
respectively.
Conclusion: There is significant difference in CSA values of
the UN at ME between the neuropathic and non-neuropathic
groups with mean CSA value above the predetermined
0.10cm2 cut-off point. High-resolution ultrasonography is
therefore useful to diagnose and follow up cases of elbow
UNN.

The supracondylar humerus fracture (SCHF) in children is
common and can be complicated with nerve injury either
primarily immediate post-trauma or secondarily posttreatment.
The concept of neurapraxic nerve injury makes
most surgeons choose to ‘watch and see’ the nerve recovery
before deciding second surgery if the nerve does not recover.
We report three cases of nerve injury in SCHF, all of which
underwent nerve exploration for different reasons. Early
reduction in the Casualty is important to release the nerve
tension before transferring the patient to the operation room.
If close reduction fails, we proceed to explore the nerve
together with open reduction of the fracture. In iatrogenic
nerve injury, we recommend nerve exploration to determine
the surgical procedure that is causing the injury. Primary
nerve exploration will allow early assessment of the injured
nerve and minimize subsequent surgery.

Causes of ulnar nerve compression in Guyon's canal are various, but thrombosis of the ulnar artery due to a single trauma is rarely reported. We report a case of ulnar nerve compression caused by traumatic thrombosis of the ulnar artery in Guyon's canal. Surgical excision of the ulnar artery thrombus and end to end anastomosis resulted in complete relief of the patient's symptoms.

We found a unique anatomical variant of the distal ulnar nerve, a neural loop encompassing the flexor carpi ulnaris during Guyon's canal exploration. Compression by the flexor carpi ulnaris during active wrist movement was suspected as the cause of ulnar neuropathy. The symptom was relieved after neurolysis and release of surrounding tissue. With regard to the ulnar side wrist pain, which is suspicious for ulnar compression syndrome at the wrist level, the surgeon should always suspect anomalous nerve branch as source of compressive neuropathic pain.

The arcade of Struthers has been described as a possible cause of ulnar nerve compression in the elbow. This paper reports two cases of ulnar neuropathy caused by the arcade of Struthers. These observations demonstrated the importance of evaluation of the arcade of Struthers in atypical high ulnar nerve palsy.

An intraneural hemangioma is an extremely rare condition. We report here on an intraneural hemangioma of the ulnar nerve. Microscopic exploration and excision of the lesion resulted in complete relief of the patient's symptoms.

10.Ulnar Neuropathy Around the Mid-Arm Combined with Martin-Gruber Anastomosis.
Annals of Rehabilitation Medicine 2012;36(5):719-723
This study reports a rare case of ulnar neuropathy around the arm with Martin-Gruber anastomosis of a moderate conduction block in the forearm segment and a severe conduction block in the arm segment. Inching tests and ultrasonography showed a lesion between 12 and 14 cm from the medial epicondyle. It is concluded that axilla stimulation may provide diagnostic clues, and inching tests and ultrasonography may be helpful for localizing a lesion.
