Background: Cubital tunnel syndrome, or ulnar nerve compression at the elbow, is the second most common compression neuropathy after carpal tunnel syndrome. Aims and Objectives: To study anatomy of the medial epicondyle in relation with nerves. Methodology: This was a cadaveric study in the 36 cadaveric hand dissected in the department of anatomy of V D Government Medical College, Latur during the two year duration i.e. January 2019 to January 2021, in the 2 years duration all the cadavers are dissected carefully and the observations were noted in the excel sheet. Data was entered in the Microsoft excel for windows 10 software and calculated Mean and Standard deviation. Result: In our study, Arm length (cm) was 28.12 ± 2.34; Length of Arcade of Struthers (AS) (cm) was 4.12 ± 1.65 Distance between AS and Medial epicondyle was 8.62 ± 0.98. Average branching pattern of nerve related to medial epicondyle i.e. for Median nerve branching (Mean ±SD) - 3.1 ± 0.94; Radial nerve branching (Mean ±SD) -2.28 ± 1.02; Ulnar nerve branching (Mean ±SD)- 2.91 ± 0.59 respectively. Conclusion: An anatomical study of medial epicondyle in relation with nerves not only important for the prevention of pathologies of elbow but also helpful in the treatment of the fractures of lower end of humerus and medical epicondyle.

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.

Abnormal Anatomy

Cubital tunnel syndrome is the second most common compression neuropathy of the upper extremity and the most common point of compression for the ulnar nerve. We present a case of ulnar nerve compression neuropathy at the elbow secondary to an abnormal subluxating medial head of triceps. A 37-year-old right hand dominant male presented with a history of bilateral medial elbow pain and ulnar distribution hand numbness. During his left cubital tunnel release surgery, the abnormal anatomy was noted. Initial subfascial anterior transposition was insufficient and had to be revised to a subcutaneous transposition intraoperatively. Failure to recognize the contribution of triceps abnormalities can lead to incomplete resolution following surgery. Surgeons should be wary of uncommon findings and adjust their approach appropriately.

Tunnel Syndrome

Background: In cubital tunnel syndrome (CuTS), chronic compression often occurs at the origin of the flexor carpi ulnaris at the medial epicondyle. Motor nerve conduction velocity (NCV) across the elbow is assessed preoperatively to corroborate the clinical impression of CuTS. The purpose of this study was to correlate preoperative NCV to the direct measurements of ulnar nerve size about the elbow at the time of surgery in patients with clinical and/or electrodiagnostic evidence of CuTS. Methods: Data from 51 consecutive patients who underwent cubital tunnel release over a 2-year period were reviewed. Intraoperative measurements of the decompressed nerve were taken at 3 locations: at 4 cm proximal to the medial epicondyle, at the medial epicondyle, and at the distal aspect of Osborne fascia at the flexor aponeurotic origin. Correlation analysis was performed comparing nerve size measurements to slowing of ulnar motor nerve conduction velocities (NCV) below the normal threshold of 49 m/s across the elbow. Results: Enlargement of the ulnar nerve at the medial epicondyle and nerve compression at the flexor aponeurotic origin was a consistent finding. The mean calculated cross-sectional area of the ulnar nerve was 0.21 cm2 above the medial epicondyle, 0.30 cm2 at the medial epicondyle, and 0.20 cm2 at the flexor aponeurotic origin ( P < .001). There was an inverse correlation between change in nerve diameter and NCV slowing ( r = −0.529, P < .001). Conclusions: For patients with significantly reduced preoperative NCV and clinical findings of advanced ulnar neuropathy, surgeons can expect nerve enlargement, all of which may affect their surgical decision-making.

The normal ulnar nerve is not visible on radiographs of the elbow. An unusual case is described in which symptoms of ulnar nerve compression with a swollen, tender ulnar nerve at the elbow developed after relatively minor trauma. Radiology suggested “Calcific Neuritis”, but this was short lived with complete regression of the symptoms.

Background: Ulnar nerve transposition (UNT) surgery is performed for the treatment of cubital tunnel syndrome. Improperly performed UNT can create iatrogenic pain and neuropathy. The aim of this study is to identify anatomical structures distal to the medial epicondyle that should be recognized by all surgeons performing UNT to prevent postoperative neuropathy. Methods: Ten cadaveric specimens were dissected with attention to the ulnar nerve. Intramuscular UNT surgery was simulated in each. Distal to the medial epicondyle, any anatomical structure prohibiting transposition of the ulnar nerve to a straight-line course across the flexor-pronator mass was noted and its distance from the medial epicondyle was measured. Results: Seven structures were found distal to the medial epicondyle whose recognition is critical to ensuring a successful anterior transposition of the ulnar nerve: (1) Branches of the medial antebrachial cutaneous (MABC) nerve; (2) Osborne’s fascia; (3) branches from the ulnar nerve to the flexor carpi ulnaris (FCU); (4) crossing vascular branches from the ulnar artery to the FCU; (5) the distal medial intermuscular septum between the FCU and flexor digitorum superficialis (FDS); (6) the combined muscular origins of the flexor-pronator muscles; and (7) the investing fascia of the FDS. Measurements are given for each structure. Conclusions: Poor outcomes and unnecessary revision surgeries for cubital tunnel syndrome can be avoided with intraoperative attention to 7 structures distal to the medial epicondyle. Surgeons should expect to dissect up to 12 cm distal to the medial epicondyle to adequately address these and prevent kinking of the nerve in transposition.

Problem Lists

AbstractPatient descriptors, or “problems,” such as “brain metastases of melanoma” are an effective way for caregivers to describe patients. But most problems, e.g., “cubital tunnel syndrome” or “ulnar nerve compression,” found in problem lists in an Electronic Medical Record (EMR) are not comparable computationally – in general, a computer cannot determine whether they describe the same or a related problem, or whether the user would have preferred “ulnar nerve compression syndrome.” Metaphrase is a scalable, middleware component designed to be accessed from problemmanager applications in EMR systems. In response to caregivers' informal descriptors it suggests potentially equivalent, authoritative, and more formally comparable descriptors. Metaphrase contains a clinical subset of the 1997 UMLS Metathesaurus and some 10,000 “problems” from the Mayo Clinic and Harvard Beth Israel Hospital. Word and term completion, spelling correction, and semantic navigation, all combine to ease the burden of problem conceptualization, entry and formalization.

Subcutaneous Transposition

Cubital tunnel syndrome is the second most commonly encountered compression neuropathy of the upper limb. Multiple techniques for surgical management have been proposed but no universally accepted algorithm for management exists. Six cadaveric upper limbs underwent ulnar nerve decompression and anterior transposition into subcutaneous and then submuscular positions. After marking nerves with tungsten, radiological examination of nerve motion was performed and nerve angulations were measured in the region of the flexor carpi ulnaris (FCU) origin. Comparison of ulnar nerves in each position revealed statistically significant greater angulation after subcutaneous transposition than after submuscular transposition with the elbow held in full flexion. This point of angulation may act as a secondary point of compression or as a focus for neuritis and scar formation. This finding can contribute to the understanding of why differing outcomes may be observed after different forms of anterior transposition.

Typical Scenario

The chapter presents the typical scenario of ulnar nerve entrapment at the elbow. The clinical picture can mimic pathology of nerve roots, of the brachial plexus, or of the ulnar nerve at different sites. Electrodiagnostic study helps to differentiate ulnar nerve entrapment from radiculopathy and to localize the site of compression, while imaging (ultrasound and MR imaging) are useful adjuncts to clinical examination. Conservative management is recommended for intermittent symptoms and absence of motor involvement. Surgical procedures include in situ, open, or endoscopic decompression and nerve transposition. Subluxation of the nerve over the medial epicondyle and recurrent or persistent neuropathy after in situ decompression are indications for transposition.
