✓ The authors report 16 consecutive cases of ulnar nerve palsy at the elbow successfully relieved by simple division of the tendinous insertions of the flexor carpi ulnaris, which form the roof of the “cubital tunnel.” They believe the more complex procedures of anterior transposition of the nerve or resection of the medial epicondyle are unnecessary, and even undesirable.

In the years 1961–1975 we have treated thirty-one men and twenty-four women for ulnar nerve palsy at Kronprinsesse Märthas Institutt. The age ranged from sixteen to seventy-eight, the majority were in mid-adult life. Thirty-four nerves on the right arm and twenty-seven on the left were operated on with anterior transposition. This clinical material has been analysed regarding aetiology and management. The neuropathy was secondary to trauma or disease at the elbow in thirty-five cases and primary with a normal elbow in twenty-six cases. At operation it was found that the neuropathy was due to fibrous compression in 36 per cent and to hypermobility in 21 per cent. In 43 per cent there were no macroscopic reasons for neuropathy. We have re-examined fifty-two patients at an average time of seven and a half years after the operation. The results were found to be excellent in 47 per cent, good in 30 per cent and poor in 23 per cent. The results were independent of duration of symptoms before the operation and independent of the surgical findings at the operation. The results were also the same whether the nerve at the transposition was put intramuscularly or just subcutanously.

Tunnel Syndrome

Compression neuropathy of the ulnar nerve at the elbow is well-recognised as cubital tunnel syndrome (CuTS). Many causes of ulnar neuropathy at the elbow have been identified. A previously unreported finding of ulnar nerve compression in the cubital tunnel caused by a thrombosed proximal ulnar recurrent artery vena comitans is described.

Operative Assessment

Background: Ulnar nerve compression at the elbow level is the second-most common entrapment neuropathy. The aim of this study was to use shear-wave elastography for the quantification of ulnar nerve elasticity in patients after ulnar nerve decompression with anterior transposition and in the contralateral non-operative side. Method: Eleven patients with confirmed diagnosis and ulnar nerve decompression with anterior transposition were included and examinations were performed on an AixplorerTM ultrasound system (Supersonic Imagine, Aix-en-Provence, France). Results: We observed significant differences at 0-degree (p < 0.001), 45-degree (p < 0.05), 90-degree (p < 0.01) and 120-degree (p < 0.001) elbow flexion in the shear elastic modulus of the ulnar nerve in the operative and non-operative sides. There were no statistically significant differences between the elasticity values of the ulnar nerve after transposition at 0-degree elbow flexion and in the non-operative side at 120-degree elbow flexion (p = 0.39), or in the ulnar nerve after transposition at 120-degree elbow flexion and in the non-operative side at 0-degree elbow flexion (p = 0.09). Conclusion: Shear-wave elastography has the potential to be used postoperatively as a method for assessing nerve tension noninvasively by the estimation of mechanical properties, such as the shear elastic modulus.

Objective: Early detection of peripheral neuropathy is extremely important as leprosy is one of the treatable causes of peripheral neuropathy. The study was undertaken to assess the role of diffusion tensor imaging (DTI) in ulnar neuropathy in leprosy patients. Methods: This was a case–control study including 38 patients (72 nerves) and 5 controls (10 nerves) done between January 2017 and June 2019. Skin biopsy proven cases of leprosy, having symptoms of ulnar neuropathy (proven on nerve conduction study) were included. MRI was performed on a 3 T MR system. Mean cross-sectional area, fractional anisotropy (FA) and apparent diffusion coefficient (ADC) values of ulnar nerve at cubital tunnel were calculated. Additional ancillary findings and appearance of base sequences were evaluated. Results: Ulnar nerve showed thickening with altered T2W signal in all the affected nerves, having an average cross-sectional area of 0.26 cm2. Low FA with mean of 0.397 ± 0.19 and high ADC with mean of 1.28 ± 0.427 x 10 −3 mm2/s of ulnar nerve in retrocondylar groove was obtained. In the control group, mean cross-sectional area was 0.71cm2 with mean FA and ADC of 0.53 ± 0.088 and 1.03 ± 0.24 x 10 −3 mm2/s respectively. Statistically no significant difference was seen in diseased and control group. Cut-off to detect neuropathy for FA and ADC is 0.4835 and 1.1020 × 10 −3 mm2/s respectively. Conclusion: DTI though is challenging in peripheral nerves, however, is proving to be a powerful complementary tool for assessment of peripheral neuropathy. Our study validates its utility in infective neuropathies. Advances in knowledge: 1. DTI is a potential complementary tool for detection of peripheral neuropathies and can be incorporated in standard MR neurography protocol. 2. In leprosy-related ulnar neuropathy, altered signal intensity with thickening or abscess of the nerve is appreciated along with locoregional nodes and secondary denervation changes along with reduction of FA and rise in ADC value. 3. Best cut-offs obtained in our study for FA and ADC are 0.4835 and 1.1020 × 10 −3 mm2/s respectively.

Ganglion Cysts

AbstractIntraneural ganglion cysts are rare mucinous cyst originating within the epineurium of peripheral nerves. They occur most commonly in the peroneal nerve. However, they have also been described in many nerves in the vicinity of synovial joints. Intraneural ganglion cysts in the upper extremity are rare. Those at the elbow joint comprise only 9% of intraneural ganglion ever reported.A 66-year-old and right-handed male patient presented with a sudden onset of right-hand weakness. He initially noticed paresthesia with decreased sensation in the lateral two digits and radial palm in his right hand. Physical examination showed thenar muscle atrophy and muscle weakness of the abductor pollicis brevis in the right hand. Preoperative diagnosis of intraneural ganglion cyst was made on the basis of characteristic magnetic resonance imaging (MRI) findings. On exploration, the ulnar nerve was identified proximal to the elbow joint. Its articular branch was addressed and divided from the elbow joint.To the best of our knowledge, addressing the articular branch connecting the glenohumeral joint for the treatment of intraneural ganglion at the elbow has only been reported twice. We experienced a rare occurrence of intraneural ganglion cyst at the elbow manifesting an ulnar neuropathy. Here, we report intraoperative findings for the articular branch-connected to intraneural ganglion of the ulnar nerve at the elbow. Early diagnosis of intraneural ganglion with precise identification of the pathology and addressing the articular branch with atraumatic dissection of ganglion cyst are essential to achieve successful treatment for this rare lesion.

Abstract Purpose To compare the rates of ulnar nerve neuropathy following ulnar nerve subcutaneous anterior transposition versus no transposition during open reduction and internal fixation (ORIF) of distal humerus fractures. Methods This was a retrospective cohort study at an academic level I trauma centre. A total of 97 consecutive patients with distal humerus fractures underwent ORIF between 2011 and 2018. All included patients were treated with plates (isolated lateral plates excluded) and had no pre-operative ulnar neuropathy. Subcutaneous ulnar nerve anterior transposition was compared versus no transposition at the time of ORIF. The main outcome measure was the rate of ulnar nerve neuropathy. The secondary outcomes were the severity of the ulnar nerve neuropathy and the rate of ulnar nerve recovery. Results Twenty-eight patients underwent subcutaneous ulnar nerve anterior transposition during ORIF, whereas 69 patients had no transposition. Transposition was associated with significantly higher rates of ulnar nerve neuropathy (10/28 versus 10/69; P = 0.027). An adjusted logistic regression model demonstrated an odds ratio of 4.8 (1.3, 17.5; 95% CI) when transposition was performed. Ulnar nerve neuropathy was classified as McGowan grades 1 and 2 in all neuropathy cases in both groups (P = 0.66). Three out of ten cases recovered in the transposition group, and five out of ten cases recovered in the no transposition group over a mean follow-up of 11.2 months (P = 1.00). Conclusion We do not recommend performing routine subcutaneous ulnar nerve anterior transposition during ORIF of distal humerus fracture as it was associated with a significant 5-fold increase in ulnar nerve neuropathy.
