Article Abstract
Objectives: To investigate the long term result of traumatic neuromas as complications of ankle arthroscopy treated by neuroma resection.
Methods: Twenty-five patients diagnosed with traumatic neuroma as complications of ankle arthroscopy were included. The standard procedure of microsurgical neuroma resection and nerve release was performed in all patients. Outcomes comparison was evaluated at 3 months, 1 year, 2 years and 5 years postoperatively. Sensory function was assessed using the British Medical Research Council (BMRC) scale. Visual analog scale (VAS) was used to evaluate pain relief. The diameter of the affected nerve was measured by ultrasound.
Results: A total of 4 (16%) patients experienced neuroma recurrence during the 5-year follow-up. In nonrecurrence cases, sensory function improvement was observed at 3 months (P < 0.0001) and 2 years (P = 0.003). There was no further statistically significant improvement to 5 years, by which time 11 patients (52.4%) had above partial recovery of sensory function (S3+, S4). The VAS pain score was 4 (3-4) preoperatively and 2 (1-2) at 3 months (Z = -4.347, P < 0.0001), which continued to improve, and patients got pain relief during the 2-5 years postoperative [2-5 years, 1 (0-1)]. The mean nerve diameter decreased at 3 months [preoperative, 20 (18.5-22); 3 months, 11 (9-12); Z = -6.082, P < 0.0001]. We did not observe a statistically significant increase of nerve diameter during the rest of follow-up time [5 years, 10 (9-11); Z = -0.765, P = 0.451].
Conclusion: Microsurgical resection was effective for traumatic neuromas of ankle cutaneous nerves. Patients experienced pain relief and partial recovery of nerve function. Most sensory recovery occurred during the first 3 months and continued to 2 years. However, neuroma recurrence was also observed in some cases.
Level Of Evidence: Ⅳ.

Department of Plastic Surgery, Birmingham Children's Hospital, Birmingham, UK.
Introduction/aims: There is a lack of clinical guidance regarding when to offer surgical exploration of traumatic nerve injuries in pediatric populations, with clinical examination, electrophysiology, and neuroimaging used variably to guide clinical decisions. This retrospective case series aimed to review the role of electrophysiology and ultrasound in guiding early surgical decisions.
Methods: This is a retrospective case series over a 4-year period at Birmingham Children's Hospital.

Background: The susceptibility of the superficial radial nerve (SRN) to form painful neuromas has been documented in previous literature. However, no epidemiological studies using validated questionnaires have been conducted to evaluate the prevalence of neuropathic pain and neuroma formation after injury to the SRN. This study aims to assess the prevalence of neuropathic pain after traumatic SRN injury.

Regenerative Peripheral Nerve Interface (RPNI) for the Management of Postamputation Pain in Oncology Patients.

Section of Plastic Surgery, Department of Surgery, University of Michigan, Ann Arbor, MI 48103.
Background: Challenges in chronic pain management among post-amputation oncology patients have led to a shift in treatment paradigms. Regenerative Peripheral Nerve Interface (RPNI) has shown promise in attenuating neuropathic pain following traumatic major limb amputations. This study evaluates the utility of prophylactic RPNI among oncology patients requiring major upper and lower extremity amputation.

Introduction And Importance: Neuromas are a nonneoplastic proliferation of Schwann cells around regenerating axons in the peripheral nerves. Traumatic neuromas are rare and can occur in any location of the body.
Case Presentation: We present a very rare case of traumatic bile duct neuroma in a male patient in his sixth decade who presented with moderate acute cholangitis and jaundice thirteen years after laparoscopic cholecystectomy with iatrogenic common bile duct injury, primary end-to-end biliary anastomosis was made.
