Background The innervated radial artery superficial palmar branch (iRASP) flap was designed to provide consistent innervation by the palmar cutaneous branch of the median nerve (PCMN) to a glabrous skin flap. The iRASP flap is used to achieve coverage of diverse volar defects of digits. However, unexpected anatomical variations can affect flap survival and outcomes.Methods Cases in which patients received iRASP flaps since April 1, 2014 were retrospectively investigated by reviewing the operation notes and intraoperative photographs. The injury type, flap dimensions, arterial and neural anatomy, secondary procedures, and complications were evaluated.Results Twenty-eight cases were reviewed, and no flap failures were observed. The observed anatomical variations were the absence of a direct skin perforator, large-diameter radial artery superficial palmar branch (RASP), and the PCMN not being a single branch. Debulking procedures were performed in 16 cases (57.1%) due to flap bulkiness.Conclusions In some cases, an excessively large RASP artery was observed, even when there was no direct skin perforator from the RASP or variation in the PCMN. These findings should facilitate application of the iRASP flap, as well as any surgical procedures that involve potential damage to the PCMN in the inter-thenar crease region. Additional clinical cases will provide further clarification regarding potential anatomical variations.

This paper reported experience with application of the snuff-box cutaneous flap in 10 patients with skin contracture in the hands. The sites with skin contracture were the first web sight in six, dorsal wrist in two, and palmar wrist in two. The flap was harvested centred by the snuff-box region with a width of 3 to 5 cm and length of 10 to 14 cm. This flap was based on the perforating branches from the radial artery in the snuff-box area. The pedicle of the flap was 4.2 mm in length. Venous drainage was through two concomitant veins of the perforating branch and the cephalic vein. Clinical application of this flap produced good results in nine cases and partial necrosis in one due to venous congention. This local cutaneous flap of the hand is recommended as a rotational pedicle flap to cover skin defects in the first web or the wrist regions. However, the flap may have disadvantages, such as failure of adequate venous return due to flap rotation or the necessity for a skin graft in the donor area when the flap is large.

INTRODUCTION Fractures of the distal radius are common upper limb injuries, representing a substantial proportion of the trauma workload in orthopaedic units. With ever increasing advancements in implant technology, operative intervention is becoming more frequent. As growing numbers of surgeons are performing operative fixation of distal radial fractures, an accurate understanding of the relevant surgical anatomy is paramount. The flexor carpi radialis (FCR) tendon forms the cornerstone of the Henry approach to the volar cortex of the distal radius. A number of key neurovascular structures around the wrist are potentially at risk during this approach, especially when the FCR is mobilised and placed under retractors. METHODS In order to clarify the safe margins of the FCR approach, ten fresh frozen human cadaver limbs were dissected. The location of the radial artery, the median nerve, the palmar cutaneous branch of the median nerve and the superficial branch nerve were measured with respect to the FCR tendon. Measurements were taken on a centre-to-centre basis in the coronal plane at the watershed level. In addition, the distances between the tendons of brachioradialis, abductor pollicis longus and flexor pollicis longus, and the radial artery and median nerve were measured to create a complete picture of the anatomy of the FCR approach to the distal radius. RESULTS The structure most at risk was the palmar cutaneous branch of the median nerve. It was located on average 3.4mm from the FCR tendon. The radial artery and the main trunk of the median nerve were located 7.8mm and 8.9mm from the tendon. The superficial branch of the radial nerve was 24.4mm from the FCR tendon and 11.1mm from the brachioradialis tendon. CONCLUSIONS Operative intervention is not without complication. We believe a more accurate understanding of the surgical anatomy is key to the prevention of neurovascular damage arising from the surgical management of distal radial fractures.

Unsuccessful reconstruction of injured fingers can lead to poor outcomes. The aim of this article was to investigate the clinical application of the radial artery superficial palmar branch flap for soft-tissue reconstruction of the finger. We treated 125 patients with various finger injuries who underwent free radial artery superficial palmar branch flap reconstruction between October 2010 and March 2015. There were 46 distal finger injuries, 25 distal finger amputation following failed replantation and 54 palmar digital injuries with tendon, bone or joint exposure requiring soft-tissue reconstruction. Of the 125 cases, 114 flap reconstructions were considered successful. We believe that a free radial artery superficial palmar branch flap transfer is credible and useful for reconstructing various finger injuries. Level of Evidence: III
