Hallux Flexus

Flexor hallucis longus muscle can adhere to the distal tibia after tibial fracture. The patient may complain of deep posteromedial ankle pain, checkrein deformity of the hallux, hallux flexus or development of hallux rigidus. Surgical treatment of release of the FHL muscle or lengthening of the FHL tendon has been proposed. We described an endoscopic approach of release of the FHL muscle from the distal tibia with the advantage of minimal soft tissue dissection.

Extensor Hallucis Longus

Trigger toe is a rare entity, with only a few cases reported in the literature. It is usually seen in ballet dancers as a result of compression of the flexor hallucis longus tendon in the tarsal tunnel beneath the medial malleolus. We report a case of trigger toe due to a constricting lesion on the extensor hallucis longus tendon. (J Am Podiatr Med Assoc 96(4): 356–358, 2006)

Ankle Ultrasound

Foot and ankle ultrasound is most commonly used to examine the tendons around the ankle in cases of suspected tears or tenosynovitis. Ultrasound however is also useful in assessing joint fluid, the ligaments, fasclitis, metatarsalgia. Impingement syndromes and in dynamic imaging or guided treatment. The Achilles tendon is the most frequently imaged tendon with the peroneal tendons, anterior and posterior tibials, extensor dlgitorum longus, extensor hallucis longus, flexor digltorum longus and flexor hallucis longus also readily accessible to ultrasound imaging.

Background. Minimally invasive surgery of the forefoot has regained popularity as an alternative to traditional open procedures. Minimally invasive hallux valgus surgery has been shown to be effective and reproducible for the treatment of mild to moderate hallux valgus. The aim of this study is to identify vital structures that are at risk for iatrogenic damage while performing a minimally invasive distal chevron osteotomy due to limited direct visualization. Methods. Ten fresh-frozen below knee cadavers were used for this study. A minimally invasive distal chevron osteotomy and medial eminence resection with a 2.2 mm × 22 mm Shannon burr was performed on each cadaver. Each specimen was dissected to expose the potential structures at risk for injury during the procedure. Structures evaluated included the medial neurovascular bundle, first metatarsophalangeal joint capsule, extensor hallucis longus tendon, flexor hallucis longus tendon, abductor hallucis tendon, and the sesamoid apparatus. Results. Ten specimens were evaluated. The dorsal medial cutaneous nerve was directly injured in 5 of the 10 cadaver specimens and intact/uninjured in the remaining 5 specimens. The flexor hallucis longus, extensor hallucis longus, adductor tendon, sesamoid apparatus, and first metatarsophalangeal joint capsule were uninjured in all specimens. Conclusion. Minimally invasive chevron distal osteotomy and medial eminence resection has a high learning curve. The resection of the medial eminence may iatrogenically injure the dorsal medial cutaneous nerve. The incidence is higher in this study than prior reported cadaveric studies and may warrant extra care to protect vital structures. Level of Evidence: Level IV: Cadaver study

Muscular Imbalance

A clawed hallux is a deformity of the great toe resulting from a muscular imbalance. Using a cadaveric foot-loading frame, we quantitatively assessed the role of the peroneus longus (PL), extensor hallucis longus (EHL), and flexor hallucis longus (FHL) on position and pressure distribution of the first ray by simulating muscle imbalances. The experimental protocol included applying seven different combinations of simulated disproportionate loads (“overpulls”) for these three muscles using midstance force values derived from the literature. This study quantified the angular change in the joints of the first ray and measured the plantar pressure beneath the head of the first metatarsal and the hallux. The results indicated that the peroneus longus was statistically the greatest contributor to the elevation of plantar pressure beneath the first metatarsal, while the EHL and FHL were primarily responsible for the angular changes resulting in the clawed hallux deformity.

Abstract Purpose The aim of the study was to examine the ligaments of the os trigonum. Methods The ankle joint magnetic resonance imaging (MRI) of 104 patients with the os trigonum (experimental group) and 104 patients without the os trigonum (control group) were re-reviewed. The connections of the os trigonum and posterior talofibular ligament (PTFL), the fibulotalocalcaneal ligament (FTCL), the paratenon of the Achilles tendon, the posterior talocalcaneal ligament (PTCL), the osteofibrous tunnel of the flexor hallucis longus (OF-FHL) and the flexor retinaculum (FR) were studied. Results The os trigonum is connected to structures. The posterior part of the PTFL inserted on the os trigonum in 85.6% of patients, whereas in all patients in the control group, the posterior part of the PTFL inserted on the posterior talar process (p < 0.05). The connection of the PTCL was seen in 94.2% of patients in the experimental group, while it was seen in 90.4% of patients in the control group (p > 0.05). The connection to the FTCL in the experimental group was 89.4%, while in the control group, it was 91.3% (p > 0.05). The communication with the paratenon was seen more often in the control group compared to that in the experimental group (31.7% vs. 63.8%, p < 0.001). The FTCL was prolonged medially into the FR in 85.6% of patients in the experimental group and in 87.5% of patients in the control group (p > 0.05). The flexor hallucis longus (FHL) run at the level of articulation between the os trigonum 63.5% and the posterior process of the talus 25% and less often on the os trigonum 11.5%. Conclusion The os trigonum is connected with all posterior ankle structures and more connections than previously reported.

Abstract Background Osteoradionecrosis (ORN) is one of the most severe complications of free fibula reconstruction after radiotherapy. The gold standard treatment of osteomyelitis involves extensive debridement, antibiotics, and sufficiently vascularized muscle flap coverage for better circulation. Therefore, we hypothesized that free fibula flap with muscle could decrease the risk of ORN. Methods This study consisted of 85 patients who underwent reconstruction with free fibula flap in head and neck cancer by a single reconstructive surgeon at Kaohsiung Veterans General Hospital over a period of 19 years (1998–2016). Patients with postoperative adjuvant radiotherapy were included in the study and were grouped by either free fibula osteocutaneous flap or free fibula osteomyocutaneous flap (with flexor hallucis longus muscle), and the incidence of ORN was compared. Results Of the 85 patients, 15 were reconstructed with osteocutaneous fibula flap and 70 were with osteomyocutaneous fibula flap. The rate of ORN or osteomyelitis was significantly lower in the muscle group (18.6%, n = 13/70 vs. 46.7%, n = 7/15, p = 0.020, Chi-square test). Conclusion Vascularized muscle transfer increases perfusion of surrounding tissues and the bone flap, thereby decreasing the incidence of osteomyelitis or osteonecrosis.
