Regarding the management of cubital tunnel syndrome, which of the following statements are true?

  1. 1.Routine internal (fascicular) neurolysis is not recommended during primary cubital tunnel decompression.

  2. 2.Mild to moderate cubital tunnel syndrome can respond to activity modification and rigid night splinting in approximately 45° of elbow extension.

  3. 3.Persistent or progressive intrinsic weakness or atrophy is an indication for surgical decompression.

  4. 4.Frank pre-operative dislocation of the ulnar nerve over the medial epicondyle on elbow flexion is an absolute contraindication to in-situ simple decompression.

  5. 5.Nerve conduction and electromyographic findings do not always correlate with the clinical severity of ulnar neuropathy at the elbow.

  1. 1. Routine internal (fascicular) neurolysis is not recommended during primary cubital tunnel decompression.

    True

    Internal neurolysis adds intraneural scarring and bleeding without demonstrated benefit over external decompression alone, and is reserved for selected revision cases with documented intraneural fibrosis.

  2. 2. Mild to moderate cubital tunnel syndrome can respond to activity modification and rigid night splinting in approximately 45° of elbow extension.

    True

    A prospective cohort of 19 patients (25 extremities) treated with rigid night splinting at 45° of elbow flexion plus activity modification showed sustained symptomatic improvement and avoidance of surgery in the majority of mild-to-moderate cases at follow-up.

  3. 3. Persistent or progressive intrinsic weakness or atrophy is an indication for surgical decompression.

    True

    Once axonal loss produces measurable intrinsic weakness or atrophy — McGowan grade III, Dellon stage 3 — conservative management is unlikely to reverse the deficit and surgical decompression is indicated to prevent further degeneration.

  4. 4. Frank pre-operative dislocation of the ulnar nerve over the medial epicondyle on elbow flexion is an absolute contraindication to in-situ simple decompression.

    False

    Pre-operative subluxation or dislocation is a relative — not absolute — indication for transposition. Several randomised trials and meta-analyses report comparable clinical outcomes for simple decompression and transposition, and most authors recommend deciding based on intra-operative stability after release of the cubital tunnel.

  5. 5. Nerve conduction and electromyographic findings do not always correlate with the clinical severity of ulnar neuropathy at the elbow.

    True

    Electrodiagnostic studies are static recordings and may miss intermittent or position-dependent compression; abnormal latencies can also persist after symptomatic resolution. Clinical examination remains essential and is graded against systems such as McGowan or Dellon.
