Role of toe flexor tendoscopy in management of an unusual cause of metatarsalgia

Abstract

The purpose of this study is to describe an endoscopic approach to toe flexor tendons at the level of metatarsal head region. And this study is a kind of retrospective case series. Three patients with toe flexor tenosynovitis were evaluated after a follow-up of 2 years after toe flexor tendoscopy. One patient suffered from infective toe flexor tendosynovitis resulting from a penetrating injury and other two patients suffered from idiopathic focal toe flexor tenosynovitis. Pre-operative metatarsalgia subsided after toe flexor tendoscopy. No endoscopy-related complication was observed. Toe flexor tendoscopy can be an effective operative means in the management of focal toe flexor tenosynovitis.

Tendoscopic management of peroneal tendon disorders

“…The presence of chronic peroneal tendon subluxation or dislocation and peroneal tenosynovitis presents with chronic peroneal pain and swelling [14]. Peroneal tendon injuries or degeneration especially if Clinical studies related to tendoscopic management of other tendon sheaths have been already published for stage 1 tibialis posterior tendon dysfunction [2,18] and for toe flexors [11]. Authors of both studies concluded that tendoscopic management is an effective and minimal invasive surgery.…”

Flexor hallucis longus tendoscopy: a technical note

“…The zone 3 FHL tendon is examined with the toe flexor tendoscopy [3]. A plantar toe portal is created with a transverse skin incision close to the insertion of the FHL tendon.…”

“…Open exploration of the tendon usually requires extensive soft tissue dissection. Different tendoscopies of the foot and ankle have been described before [2][3][4][5]. We describe a tendoscopic approach to deal with the flexor hallucis tendon pathology.…”

Flexor Hallucis Longus Tenosynovitis and First Metatarsophalangeal Synovitis After Penetrating Nail Prick Injury: Treated by Zone 3 Flexor Hallucis Longus Tendoscopy and Metatarsosesamoid Arthroscopy

“…The extensive soft tissue dissection may result in painful scarring especially on the plantar side. Recently, techniques such as FHL tendoscopy 5,6 and arthroscopy of the metatarsosesamoid compartment [7][8][9] have been reported. For performing tendoscopy, the FHL tendon can be divided into 3 zones: zone 1 from the musculotendinous junction to the fibro-osseous orifice of the posterior talar processes; zone 2 from the orifice to the master knot of Henry; and zone 3 from the master knot of Henry to phalangeal insertion of the tendon.…”

“…Zone 3 FHL tendoscopy provides access to the FHL tendon around the MTP-1 joint. 5,6 These techniques together with the classic MTP-1 arthroscopy allow thorough exploration and debridement of the MTP-1 joint and the flexor tendon sheath. The purpose of this Technical Note is to report the combined arthroscopic and tendoscopic approaches to address the MTP-1 joint and FHL tendon pathologies.…”
