INTRODUCTION {#sec1-1}
============

Dropped Hallux is not a common entity and we present a simplified approach for its correction. We transferred the first (1^st^) slip of EDL and also the extensor hallucis brevis (EHB) to extensor hallucis longus (EHL), thus achieving the final postoperative result as depicted in the figures and videos. Patient subsequently developed good range of motion postoperatively with 0-15 degrees of extension and 0-15 degrees of flexion.

CASE REPORT {#sec1-2}
===========

A 55-year-old male sustained a closed fracture of the right tibia following a road traffic accident. On admission, his vitals were stable. Circulation of the extremity was compromised, so immediate fasciotomy was done to relieve the excessive limb swelling. His X-rays were done revealing a Schatzker\[[@CIT1]\] type 6 injury along with dropped right hallux. Patient was taken up for surgery for his fracture tibia and plating was done along with split skin grafting of the fasciotomy wound and primary closure of his other wounds. The hallux was treated symptomatically by splinting and giving a slab with foot in dorsiflexion. Patient recovered completely except for the dropped hallux. Conservative management of the same was continued for six weeks after which surgical intervention was planned.

Procedure {#sec2-1}
---------

Surgical exposure was done exposing the extensor hallucis longus (EHL), extensor hallucis brevis (EHB) and the 1^st^ slip of the extensor digitorum longus (EDL) tendon was exposed. Our approach has been explained with the help of a line diagram \[[Figure 1](#F0001){ref-type="fig"}\]. We anchored the EHL tendon to EHB tendon and instead of completely detaching the 1^st^ slip of EDL, we longitudinally split it starting 1.5 cm proximal to its insertion as shown in the line diagram \[[Figure 1](#F0001){ref-type="fig"}\] and anchored it to the EHL.

Postoperative protocol {#sec2-2}
----------------------

Initially splintage was continued for six weeks followed by physiotherapy, which was combined with night splintage for another two weeks. The physiotherapy done was active under supervision initially and patient was subsequently trained to do the same all by himself. The postoperative recovery was satisfactory with a small scar line \[[Figure 2](#F0002){ref-type="fig"}\], which healed uneventfully. The range of motion was measured using goniometer. The range of motion postoperatively is 15 degrees of extension and 15 degrees of flexion. The ranges of motion of both sides have been compared in [Table 1](#T0001){ref-type="table"}. Active extension of the hallux is shown in [Figure 3](#F0003){ref-type="fig"}. Both active flexion and extension movements have been depicted in the Videos [1](#SD1){ref-type="supplementary-material"} and [2](#SD2){ref-type="supplementary-material"}.

DISCUSSION {#sec1-3}
==========

Damage to either the EHL muscle belly or the motor nerve to EHL are uncommon causes of the dropped hallux.\[[@CIT2]\] This problem can occur after injury, high tibial osteotomy or intramedullary nailing of a fractured tibia.\[[@CIT1]\] Very little literature is present on the treatment aspects of the same. Similar technique which we have described could not be identified after extensive search of literature. The cause of the dropped hallux in our case was most probably due to detachment of the EHL tendon from its origin following the trauma. There was no sensory loss ruling out any injury to the deep peroneal nerve.

Dynamics of function {#sec2-3}
--------------------

Our transfer follows the general principles of tendon transfer. Firstly, we ensured before the transfer that the joints were supple and there was no soft tissue scarring in the area of transfer. Secondly, we have used both the extensors (i.e., EHB and 1^st^ slip of EDL), which are agonists for the extensor function we intended to achieve by the transfer. Thirdly, the transfer tendons were lying in a straight path as required for effective functioning of the tendon transfer. Lastly, we have not compromised any function due to the transfer since we have split the 1^st^ slip of EDL longitudinally and transferred it to the EHL thereby retaining the active 2^nd^ toe extension. Postoperatively the range of motion was also satisfactory with only 3 degrees of extensor lag as shown in [Table 1](#T0001){ref-type="table"}.

Tendon transfers have been described for clawing of great toe viz. the Jones\[[@CIT3]\] tendon transfer and the Hibbs\[[@CIT4]\] procedure, however, transfers for dropped hallux post-trauma have not been clearly mentioned or detailed in literature. We have presented a simplified approach which is quick with less tedious dissection, and produces good results and patient satisfaction.
