symptoms of failed ulnar nerve transposition

As reported before, among 30 revisions, Gabel and Amadio attributed the surgical failures to persistent compression at the medial intermuscular septum (16), cubital tunnel or FCU arcade (13), and the arcade of Struthers and deep flexor aponeurosis (7). Most revision case series have reported on and supported submuscular transposition for unclear reasons. USA.gov. Dellon stated, “that little more than personal bias is available for guidance in selecting treatment.” The same can be applied to revision cubital tunnel surgery. Failure may be due to diagnostic, technical, or biologic factors. Understanding the patient’s symptoms both before and after the initial surgery, including subtle difference in pain and parasthesias, will guide the appropriate workup. Ulnar nerve damage should be treated by a doctor. Mackinnon and Novak urged meticulous technique in the primary setting to prevent neuroma formation and electrocautery “capping” of excised neuroma nerve endings in the revision setting to prevent recurrence of painful neuromas. 26 Failed Ulnar Nerve Transposition Due to Unrecognized Snapping of the Medial Triceps Robert J. Spinner and Rajiv Midha Case Presentation A 40-year-old psychiatrist presented with increasingly troublesome paresthesias in the ulnar 1½ digits of the dominant left hand accompanied by moderate elbow pain and snapping along the medial aspect of the elbow. He did add that in recurrent cases, the most favorable results were achieved when an internal neurolysis was performed in addition to a submuscular transposition. Revision ulnar neuroplasty should be performed in cases of recurrence or persistence of symptoms or signs of ulnar entrapment neuropathy at the elbow following cubital tunnel release, with or without previous epicondylectomy or anterior transposition. Technical errors and the development of perineural fibrosis necessitate revision surgery, while… Hand (N Y). In this article, they felt the medial intermuscular septum is only a site of compression if it is not resected with transposition. Epub 2016 May 12. Cureus. The role of repeat electrodiagnostic studies remains controversial. If the medial antebrachial cutaneous branch is injured, we would recommend primary repair using miscrosurgical technique. Hypothenar hammer syndrome may also present with ulnar nerve symptoms of the hand, although the primary etiology is an injury to the ulnar artery, leading to cold ulnar-sided digits but the ulnar nerve may also be involved. This exposure and nerve dissection will most likely not allow the nerve to stay stable in its native location (assuming an in situ decompression was performed during the index operation), and it will therefore most likely need to be transposed if it has not been already. If it remains difficult to dissect the nerve free from the surrounding scar tissue, we recommend including a cuff of scar tissue around the nerve to avoid damaging it. Motor studies are clearly less useful in the evaluation of patients with absent or subtle examination findings. Etiology and treatment. Intermuscular aponeuroses between the flexor muscles of the forearm and their relationships with the ulnar nerve. They found this in cases of both simple decompressions as well as transpositions. Discussion of surgical treatment failure for cubital tunnel syndrome warrants defining the term “failure,” and reviewing its causes and the optimal workup and treatment for this condition. Ulnar nerve transposition or anterior transposition of the ulnar nerve is an outpatient surgical procedure that repositions the nerve to relieve pressure and prevent permanent ulnar nerve damage. Starting proximally, provocative testing for cervical nerve root impingement (Spurling test and Lhermitte sign), and thoracic outlet maneuvers (Adson, Wright, and Roos stress test) should be evaluated. More commonly, branches of the medial antebrachial cutaneous nerve are injured in the superficial dissection as they cross the incision within 6 cm proximal and distal to the medial epicondyle. The patient may see the index procedure as a failure if there is no change in symptoms or the improvement is mild or negligible. NIH Compression of the neurovascular bundle at the superior thoracic outlet, which is known as thoracic outlet syndrome, can also mimic cubital tunnel syndrome. The first step is to identify the nerve. We believe that success after revision surgery depends on finding and removing any external compression on the ulnar nerve and then placing the nerve in a stable bed with no subluxation. A patient may notice worsening symptoms of the ulnar nerve after surgery. Also, intrinsic muscle atrophy once present will most likely not recover. Vogel, and colleagues reported on 18 patients in whom most (15) had subcutaneous transposition, and found the most common operative findings to be perineural scarring (16). The surgeon must recognize the possibility of irreversible nerve damage, communicate this to the patient, and manage the patient’s expectations. An electrodiagnostic study will also aid in the diagnosis. In Mackinnon and Novak’s review of 100 failed ulnar nerve cases, they saw 73 medial antebrachial cutaneous neuromas, and felt this to be one of the major causes of failed decompression and transposition.
