Objective: To determine anatomical variation of the sural nerve (SN) by ultrasonography (US) and compare sensory nerve action potential (SNAP) of the SN obtained by a control method to that obtained with adjusted method using US.
Methods: Eighty legs of 40 healthy volunteers were enrolled. The location and formation of SN were investigated through US. Two methods of nerve conduction study (NCS) were then performed. In the control method, the cathode was placed 14 cm proximal to the lateral malleolus and the greatest SNAP amplitude was obtained by moving the cathode medially or laterally from just lateral to the calf-mid line. In adjusted NCS, the exact SN union site was stimulated in type 1. In other SN types, the stimulation was done directly over the nerve and the distance from the lateral malleolus was set to be 14 cm.
Results: It was found that 73.8% of the SNs were type 1, 22.5% were direct continuation of MSCN (type 2), and 3.8% were MSCN and LSCN without communicating (type 4). However, type 3 was not found. The union point in type 1 SN was 12.6±2.5 cm proximal to the lateral malleolus and 1.4±0.7 cm lateral to the calf-midline. After stimulation adjustment, SNAP amplitude in type 1 SN was significantly increased (20.7±5.5 μV vs. 27.1±6.7 μV).
Conclusion: Anatomical variation of SN and its location were verified by US. US provides additional information for conducting sural NCS and helps obtain more accurate.

Operation Room, Hunan University of Medicine General Hospital, No. 144, Jinxi South Road, Huaihua City, Hunan Province, 418000, China.
Objective: The surgical team in this study examined the efficacy of a modified reverse sural neurocutaneous flap repair in treating soft tissue defects of the ankle and foot caused by accidents.
Methods: This study enrolled 89 patients treated for soft tissue defects of the ankle or foot between January 2007 and December 2023. The patients were divided into two groups: 44 patients underwent a modified reverse sural neurocutaneous flap repair, while 45 received traditional treatment.

Longitudinal split fracture of the lateral malleolus causing tarsocrural subluxation in a Siberian Husky.

A 4-year-old Siberian Husky was referred for bilateral hock trauma after being involved in a road traffic accident. The dog sustained a grade 3 shearing injury to the medial right hock with tibiotarsal subluxation, which was managed with a transarticular frame. The left hock sustained a rare open longitudinal split fracture of the lateral malleolus, resulting in lateral tarsocrural instability.

Orthopedics and Traumatology Unit, University of Verona, Verona, Italy.
Background: Isolated distal fibula fractures (DFF) are usually treated with open reduction and internal fixation (ORIF) and non-weight-bearing protocols. The study assessed the outcomes of immediate weight-bearing on DFF healing and stability after lateral locking plating.
Materials And Methods: For this study, 49 patients affected by isolated DFF were enrolled.
Review of Outcomes of Intramedullary Fibular Nails in the Management of Ankle Fractures in Adults.

Distal fibula fractures involving the ankle are one of the most common fractures, often requiring open reduction and internal fixation with plates and screws. The increased incidence of potential wound complications arising from open reduction methods led to a rejuvenated interest in the application of minimally invasive methods like intramedullary nailing of the fibula in the management of ankle fractures and isolated distal fibular fractures. A literature search was performed using Medline, Cochrane, and Embase from 1993 to 2023.
