Free Functional Muscle Transfer following Upper Extremity Sarcoma Resection: A Case Report.

Functional reconstruction of the upper extremity has traditionally involved tendon transfer or pedicled muscle transfer. The gracilis free functional muscle transfer remains as an excellent option for restoration of finger flexion. Here, we provide a case report of a 35-year-old man diagnosed with left forearm high-grade epithelioid sarcoma who underwent innervated free gracilis transfer and a secondary free flap, the profunda artery perforator flap, through a single donor-site incision to expand soft tissue coverage.

Staged Phrenic Nerve Elongation and Free Functional Gracilis Muscle Transplantation-A Possible Option for Late Reconstruction in Chronic Brachial Plexus Injury.

Purpose: In patients with late brachial plexus birth injuries, sequelae after acute flaccid myelitis, or chronic adult brachial plexus injury, donor nerves for functioning muscle transplantation are often scarce. We present the results of a potential strategy using the phrenic nerve with staged free gracilis transplantation for upper extremity reanimation in these scenarios.

Methods: A retrospective review was performed on an institutional database of brachial plexus injury or patients with palsy.

Functional Outcome Comparison of Free Gracilis Muscle Anchoring Methods in Patients with Facial Paralysis: Upper Lip Red Line Incision versus Facelift Incision Approach.

Background:  The greatest challenge of a free-muscle transfer in facial reanimation surgery is anchoring muscle to perioral soft tissue. An additional incision provides a better way to anchor the transferred muscle but leaves a visible scar. Herein, we compared the functional and aesthetic outcomes in a conventional facelift incision approach with and without the addition of a red line incision.

Procedures for obtaining muscle physiology parameters during a gracilis free-functioning muscle transfer in adult patients with brachial plexus injury.

A complete understanding of muscle mechanics allows for the creation of models that closely mimic human muscle function so they can be used to study human locomotion and evaluate surgical intervention. This includes knowledge of muscle-tendon parameters required for accurate prediction of muscle forces. However, few studies report experimental data obtained directly from whole human muscle due to the invasive nature of these experiments.

Lessons Learned from 30 Years of Transverse Myocutaneous Gracilis Flap Breast Reconstruction: Historical Appraisal and Review of the Present Literature and 300 Cases.

Background: Happy 30th birthday to the transverse myocutaneous gracilis (TMG) flap. Since 1991 the TMG flap has been used to reconstruct a wide variety of defects and became a workhorse flap and reliable alternative to the deep inferior epigastric perforator (DIEP) flap in many breast reconstruction services worldwide. This manuscript sheds light on the history and success of the TMG flap by critically reviewing the present literature and a series of 300 patients receiving a breast reconstruction.

In vivo human gracilis whole-muscle passive stress-sarcomere strain relationship.

We measured the passive mechanical properties of intact, living human gracilis muscles (n=11 individuals, 10 male and 1 female, age: 33±12 years, mass: 89±23 kg, height: 177±8 cm). Measurements were performed in patients undergoing surgery for free-functioning myocutaneous tissue transfer of the gracilis muscle to restore elbow flexion after brachial plexus injury. Whole-muscle force of the gracilis tendon was measured in four joint configurations (JC1-JC4) with a buckle force transducer placed at the distal tendon.

Simple, but effective: Nasal splinting for airway securement in free flap reconstruction following orbital exenteration.

Orbital exenteration is a disfiguring procedure that often results in free tissue transfer for reconstructive purposes. The reconstructive focus is the obliteration of dead space while sparing the nasal airway, particularly if the medial orbital wall was resected. Prolapse of transferred tissue into the nasal airway may cause breathing difficulties drastically compromising quality of life.

Lessons from Gracilis Free Tissue Transfer for Facial Paralysis: Now versus 10 Years Ago.

Outcomes following free gracilis muscle transfer have steadily improved during the past decade. Areas for continued improvement include re-creating natural smile vectors, improving midface symmetry, minimizing scarring, improving spontaneity, and increasing reliability using various neural sources. Outcome standardization, pooled data collection, and remote data acquisition methods will facilitate comparative effectiveness research and continued surgical advancements.

Temporalis Tendon Transfer Versus Gracilis Free Muscle Transfer: When and Why?

Temporalis tendon transfer (T3) and gracilis free muscle transfer (GFMT) are popular techniques in lower facial rehabilitation when reinnervation techniques are unavailable. T3 involves a single-stage outpatient procedure resulting in immediate improvement in resting symmetry and a volitional smile. GFMT allows a spontaneous smile, customized vectors, and increased excursion but requires longer surgical time, a delay before movement, and specialized equipment.

Adductor magnus muscle transfer to restore knee extension: Anatomical studies and clinical applications.

Background: Loss of knee extension causes significant impairment. Though nerve-based reconstruction is preferable in cases of femoral nerve palsy or injury, these surgeries are not always appropriate if the pathology involves the quadriceps muscles or presentation too late for muscle reinnervation. Muscle transfers are another option that has been underutilized in the lower extremity.

Percutaneous Reconstruction of the Medial Patello-Femoral Ligament Using Dynamic Gracilis Tendon Transfer.

Background: Many techniques have been described for reconstructing the medial patello-femoral ligament (MPFL), using a variety of transplants and fixation methods to treat patello-femoral dislocation. The main challenge with static transfers is to position the femoral fixation point at the site that best restores MPFL anisometry. The objective of this cadaveric study was to propose a version of the initially described dynamic gracilis transfer technique that can be performed percutaneously.

Workhorse Free Functional Muscle Transfer Techniques for Smile Reanimation in Children with Congenital Facial Palsy: Case Report and Systematic Review of the Literature.

Background: Pediatric facial palsy represents a rare multifactorial entity. Facial reanimation restores smiling, thus boosting self-confidence and social integration of the affected children. The purpose of this paper is to present a systematic review of microsurgical workhorse free functional muscle transfer procedures with emphasis on the long-term functional, aesthetic, and psychosocial outcomes.

Alternative flaps in autologous breast reconstruction.

The gold standard for autologous reconstruction in the post-mastectomy patient remains the deep inferior epigastric artery perforator flap, although many women may not be candidates for abdominally based free tissue transfer. In this scenario, there are several other donor site options based from the thigh (transverse and diagonal upper gracilis flaps, profunda artery perforator flap, lateral thigh flap) and trunk (lumbar artery perforator flap, superior and inferior gluteal artery perforator flaps). This study will review the history, relevant anatomy, surgical technique and outcomes for alternative flaps in autologous reconstruction.

Dynamic Hemitongue Defect Reconstruction With Functional Gracilis Muscle Free Transfer.

Background: Because the tongue consists of 26 intrinsic and extrinsic muscles, even hemiglossectomy, which preserves some of the tongue and its muscles, leads to functional morbidity in speech and swallowing. Subsequent reconstruction using a conventional fasciocutaneous flap results in limited functional recovery. This study compared the functional recovery of patients who underwent hemiglossectomy based on the fasciocutaneous free flap with or without dynamic gracilis muscle flap reconstruction.

Surgical outcome for colorectal or urinary tract-related fistula: Usefulness of vascularized tissue transfer-a retrospective study.

Background: It is challenging to manage colorectal or urinary tract-related fistula. We typically treat colorectal or urinary tract-related fistula with a vascularized tissue transfer. This study aimed to analyze the outcomes of our surgical treatments for colorectal or urinary tract-related fistula.

Combined medial patellofemoral and medial patellotibial reconstruction for patellar instability: a PRISMA systematic review.

Background: The medial patellofemoral ligament (MPFL) works in association with the medial patellotibial ligament (MPTL) and the medial patellomeniscal ligament (MPML) to impart stability to the patellofemoral joint. The anatomy and biomechanical characteristics of the MPFL have been well described but little is known about the MPTL and MPML. Several reconstruction procedures of the MPFL with semitendinosus, gracilis, patellar and quadriceps tendons, allografts and synthetic grafts have been described.

Microsurgical Tissue Transfer in Breast Reconstruction.

Autologous breast reconstructions have grown in popularity because of their durability, aesthetic outcomes, symmetry, increase in external beam radiotherapy use, and potential aesthetic enhancement at the donor site. Increasing patient expectations for predictable high aesthetic outcomes with minimal complications or need for further procedures has been met by refinement in the use of flaps. The authors' microsurgical breast reconstruction center aims to provide this while delivering efficient service.
