Introduction: Isolated musculocutaneous nerve injuries occur rarely due to their anatomical location. We present our patient with a musculocutaneous nerve injury in a motorcyclist. Case: The patient was initially treated for a motorcycle accident. Further examination of the patient revealed impaired elbow flexion and numbness of the lateral forearm. Electromyography confirmed impaired function of the musculocutaneous nerve. After 3 months, the patient‘s condition did not show any improvement, neither electromyography confirmed recovery of the nerve activity, so surgical treatment was planned. In the surgical revision, neuroma-in-continuity was discovered and resected. The resulting nerve defect was 6 cm long. We provided nerve grafting using sural nerve from the right lower limb. After surgery, the patient began physical therapy and electrical stimulation. Two years later, the patient reached complete recovery of muscle strength. Conclusion: Due to the lack of improvement after a 3-month period, we proceeded with a surgical revision, which demonstrated a complete lesion of the nerve that could not heal spontaneously. Therefore, we opted for the nerve graft method and the patient regained full function of elbow flexors.

INTRODUCTION: Radial nerve palsy after humeral shaft fractures is often associated with formation of a neuroma in continuity. The current standard of treatment is neuroma resection and nerve grafting with contentious results. Anterior transposition of the radial nerve may reduce the length of its path, allowing reconstruction by primary suture. The aim of this study was to determine the maximum length of radial nerve defect that can be treated by the anterior transposition to allow primary suture to be performed. METHODS: We use 10 arms from five fresh cadavers. The radial nerve was dissected in the lateral inter-muscular septum and along the anterior aspect of the forearm. The radial nerve was transected at the level of the spiral groove and both stumps were than transposed anterior to the medial inter-muscular septum. The length of tension-free overlap that could be achieved was measured. RESULTS: The average length of the overlap at zero degrees of elbow flexion was 10.00 ± 1.84 mm. Theoretically, this will allow a defect of 20 ± 3.69 mm SD to be treated by primary suture. CONCLUSION: Our results suggest that anterior transposition can be used for radial nerve defects up to 2 cm; however, dissection of both stumps proved to be challenging.

Introduction: It is often questioned whether to perform replantation or revision amputation for amputation injuries in elderly patients and smokers. According to the current indication criteria, neither old age nor smoking in the absence of other risk factors are considered to be risk factors for replantation failure. However, many microsurgeons still may make the decision not to perform digital replantation based solely on these factors. Material and methods: In order to evaluate the influence of both factors, we provided univariate and multivariate analyses of patients who underwent replantation at our centre during a 10-year period. We divided patients in two groups according to age (< and ≥ 60 years) and smoking status. Results: In the univariate analysis, there were no differences in immediate results between the two age groups. In the multivariate analysis, no statistical difference was found in neither long-term nor short-term results between the two age groups and between smokers and non-smokers. Conclusion: Smoking and age should not be considered the only risk factors when deciding whether to perform digital replantation.
