  • anatomical feasibility study of Flexor Hallucis Longus transfer in treatment of achilles tendon and posteromedial portal of ankle arthroscopy
    Surgical and Radiologic Anatomy, 2018
    Co-Authors: Linger Wang, Dachuan Xu, Wenwei Dong, Keith L Wapner
    Abstract:

    Purpose The aim of this study was to evaluate the occurrence of anatomical variations of the musculotendinous junction of the Flexor Hallucis Longus (FHL) muscle, the relationship between FHL tendon or muscle and the tibial neurovascular bundle at the level of the posterior ankle joint in human cadavers.

  • anatomical study of the neurovascular in Flexor Hallucis Longus tendon transfers
    Scientific Reports, 2017
    Co-Authors: Wenwei Dong, Dachuan Xu, Keith L Wapner
    Abstract:

    The transfer of the Flexor Hallucis Longus tendon or Flexor digitorum Longus tendon is frequently used for the treatment of posterior tibial tendon insufficiency or chronic Achilles tendinopathy. According to several anatomical studies, harvesting the Flexor Hallucis Longus (FHL) tendon may cause nerve injury. Sixty-eight embalmed feet were dissected and anatomically classified to define the relationship between Henry’s knot and the plantar nerves. Two different configurations were identified. In Pattern 1, which was observed in 64 specimens (94.1%), the distance between the medial plantar nerve and Henry’s knot was 5.96 mm (range, 3.34 to 7.84, SD = 1.12). In Pattern 2, which was observed in 4 specimens (5.9%), there was no distance between the medial plantar nerve (MPN) and Henry’s knot. No statistically significant difference was observed according to gender or side (p > 0.05). A retraction was performed to harvest the FHL through the posteromedial hindfoot incision using a single minimally invasive technique, and the medial and lateral plantar nerve lesions were scrupulously assessed. In conclusion, medial and lateral plantar nerve injuries did not occur more frequently, even after performing a single minimally invasive incision to harvest the FHL tendon, due to the large distance between the FHL tendon and the medial and lateral plantar nerves.

  • anatomical study for Flexor Hallucis Longus tendon transfer in treatment of achilles tendinopathy
    Surgical and Radiologic Anatomy, 2015
    Co-Authors: Keith L Wapner, Wenwei Dong, Dachuan Xu
    Abstract:

    Purpose The purpose of the study was to describe the anatomical variations of the connection between the Flexor Hallucis Longus (FHL) and Flexor digitorum Longus (FDL) tendons in the knot of Henry in Asians, and quantify the length of FHL tendon graft with different incisions.

  • mr imaging findings of entrapment of the Flexor Hallucis Longus tendon
    American Journal of Roentgenology, 2001
    Co-Authors: Lawrence D Lo, Mark E Schweitzer, Keith L Wapner, Paul J Hecht
    Abstract:

    OBJECTIVE. In this retrospective study, we describe the MR imaging patterns of various causes of Flexor Hallucis Longus tendon entrapment.CONCLUSION. Entrapment of the Flexor Hallucis Longus tendon may be due to an enlarged os trigonumtarsitarsi, calcaneal fracture, and soft-tissue scar. These disorders have characteristic imaging findings that may be revealed on MR imaging.

  • Repair of chronic achilles tendon rupture with Flexor Hallucis Longus tendon transfer
    Operative Techniques in Orthopaedics, 1994
    Co-Authors: Keith L Wapner, Paul J Hecht
    Abstract:

    A technique is described for reconstruction of chronic Achilles tendon rupture using the Flexor Hallucis Longus tendon. Follow-up on seven patients (mean age 52 years) is provided (average follow-up 17 months, range 3 to 30 months). All patients were re-examined to assess postoperative range of motion, scar healing, and sensation. Motor strength was assessed by Cybex testing. Subjective satisfaction was examined by completion of a questionnaire. All patients had a satisfactory return to function.

  • release of the Flexor Hallucis Longus tendon in ballet dancers
    Journal of Bone and Joint Surgery American Volume, 1996
    Co-Authors: George J Kolettis, Lyle J Micheli, J D Klein
    Abstract:

    Thirteen female ballet dancers had an operative release of the Flexor Hallucis Longus tendon because of isolated stenosing tenosynovitis, and the results were reviewed after a mean duration of follow-up of six years and six months (range, two to ten years). All of the patients danced at the advanced or professional level, and all had failed to respond to non-operative management. The mean age of the patients at the time of the operation was twenty years (range, thirteen to twenty-six years). Symptoms, which included pain and tenderness over the medial aspect of the subtalar joint, had been present for a mean of six months (range, two to twelve months) preoperatively and were exacerbated by jumping and by attempts to perform en pointe work. Crepitus was present in six patients, and triggering was present in three. No patient had evidence of a symptomatic os trigonum. Postoperatively, all patients participated in a formal physical-therapy program for a mean of nine weeks (range, four to thirteen weeks). All patients returned to dancing, within a mean of five months (range, two to nine months), and eleven reached a level of full participation in dancing without restriction. At the time of the most recent follow-up, all patients noted improvement compared with the preoperative condition. Eight patients were professional ballet dancers, four were students at advanced ballet schools, and one had stopped performing ballet for reasons unrelated to the tenosynovitis of the Flexor Hallucis Longus. In addition, two of the students had decided not to pursue careers in dancing because of persistent, but greatly diminished, symptoms. No complications were noted in this series. We concluded that an operative release of the Flexor Hallucis Longus is effective for the treatment of isolated stenosing tenosynovitis in female ballet dancers who place high demands on the foot and ankle and for whom non-operative treatment has failed.

  • tenosynovitis of the Flexor Hallucis Longus in a long distance runner
    Medicine and Science in Sports and Exercise, 1996
    Co-Authors: George H Theodore, George J Kolettis, Lyle J Micheli
    Abstract:

    ABSTRACT Chronic inflammation of the Flexor Hallucis Longus (FHL) tendon can result in stenosing tenosynovitis. This condition has been well documented in ballet dancers. It usually presents as posteromedial ankle pain, worsened by plantarflexion activities. Although conservative therapy benefits most patients, some recalcitrant cases may require surgical intervention. This is the first case report that describes the occurrence of this condition in a runner with an anomalous Flexor Hallucis Longus muscle.

  • os trigonum syndrome with Flexor Hallucis Longus tenosynovitis in a professional football referee
    Medicine and Science in Sports and Exercise, 1999
    Co-Authors: Mitchell E Cooper, Preston M Wolin
    Abstract:

    The presentation of posterior ankle pain in any patient poses a diagnostic dilemma. The os trigonum syndrome and Flexor Hallucis Longus stenosing tenosynovitis have been reported to occur in professional and amateur ballet dancers. It is important to consider these diagnoses in a patient who is not a dancer, as is shown in the case presented here. The patient in this case is a professional referee who injured his ankle while working on artificial turf. The treatment for os trigonum syndrome and Flexor Hallucis Longus tenosynovitis is initially conservative, but in refractory cases, surgical removal of the os and release of the Flexor Hallucis Longus tendon can be successfully performed. This is the first reported case of os trigonum syndrome and Flexor Hallucis Longus tenosynovitis presenting simultaneously in a patient who is not a dancer.

  • repair of chronic achilles tendon rupture with Flexor Hallucis Longus tendon transfer
    Foot & Ankle International, 1993
    Co-Authors: Keith L Wapner, Paul J Hecht, Gail S Pavlock, Francis Naselli, Robyn Walther
    Abstract:

    A new technique is described for reconstruction of chronic Achilles tendon rupture using the Flexor Hallucis Longus tendon. Follow-up on seven patients (mean age 52 years) is provided (average follow-up 17 months, range 3–30 months). All patients were re-examined to assess postoperative range of motion, scar healing, and sensation. Motor strength was assessed by Cybex testing. Subjective satisfaction was examined by completion of a questionnaire. There were no postoperative infections, skin losses, or re-ruptures. Each patient developed a small but functionally insignificant loss in range of motion in the involved ankle and great toe. All patients had a satisfactory return of function. One patient required a molded foot-ankle orthosis for extended ambulation but was able to play golf.
