Reconstruction of Large Full-Thickness Abdominal Wall Defects Using a Free Functional Latissimus Dorsi Muscle.

Introduction: The large full-thickness abdominal wall defect has to be treated by considering anatomical and functional requirements. The abdominal wall must regain total physiological function, which means that the full thickness abdominal wall defect must be reconstructed anatomically, not only according to the anatomical requirements but also maintaining the functional dynamic voluntary movement. Defects in the abdominal wall alter respiratory mechanics and can impair the diaphragm function. Additionally, muscles of the anterolateral abdominal wall increase the stability of the lumbar region of the vertebral column by tensing the thoracolumbar fascia and by increasing intraabdominal pressure. Materials and Methods: The timing and method of reconstruction must be chosen depending upon the etiology of the defect. Severe traumatic injuries, abdominal wall infections, necrotizing soft tissue loss, or sepsis needs to undergo staged reconstruction following adequate debridement to control the infectious process, establish the zone of injury, and for proper treatment of intraabdominal pathology, thereby achieving temporary primary closure using split-thickness skin grafting to the viscera. At the time of definitive reconstruction, deep skin graft dermabrasion give us a facial-like layer with adequate strength to stabilize the static abdominal wall. This dermal layer is supported by free functional (innervated) latissimus dorsi muscle (fLDM), giving full anatomical coverage and functional stability. After oncologic resections full-thickness abdominal wall reconstruction was performed immediately with a combination of fLDM flaps and meshes. Results: A total of 14 patients underwent abdominal wall reconstruction using the fLDM flap. Staged reconstruction was applied in 8 cases. In the remaining six cases, two had no mesh support, three had synthetic mesh, and one had a fascial graft, which were covered with fLDM flap. There were no free flaps failure. One flap revision due to venous anastomosis thrombosis was performed. Donor site seromas occurred in 5 cases and were treated with punction and direct doxycycline injection. Electromyographic testing postoperatively confirmed reinnervation of transplanted LDM. Conclusion: Using fLDM as a definitive solution, we are not only able to repair soft tissue defects, but also reconstruct voluntary contractility and dynamic natural functional abdominal wall. Transplanted LDM offers enough contractile capacity and strength to replace the function of the missing abdominal wall muscles.

Long-term outcome after hand and forearm transplantation - a retrospective study.

Between 2000 and 2014, five patients received bilateral hand (n = 3), bilateral forearm (n = 1), and unilateral hand (n = 1) transplants at the Innsbruck Medical University Hospital. We provide a comprehensive report of the long-term results at 20 years. During the 6-20 years follow-up, 43 rejection episodes were recorded in total. Of these, 27.9% were antibody-related with serum donor-specific alloantibodies (DSA) and skin-infiltrating B-cells. The cell phenotype in rejecting skin biopsies changed and C4d-staining increased with time post-transplantation. In the long-term, a change in hand appearance was observed. The functional outcome was highly depending on the level of amputation. The number and severity of rejections did not correlate with hand function, but negatively impacted on the patients´ well-being and quality of life. Patient satisfaction significantly correlated with upper limb function. One hand allograft eventually developed severe allograft vasculopathy and was amputated at 7 years. The patient later died due to progressive gastric cancer. The other four patients are currently rejection-free with moderate levels of immunosuppression. Hand transplantation remains a therapeutic option for carefully selected patients. A stable immunologic situation with optimized and individually adopted immunosuppression favors good compliance and patient satisfaction and may prevent development of DSA.

Functional and Psychosocial Outcomes of Hand Transplantation Compared with Prosthetic Fitting in Below-Elbow Amputees: A Multicenter Cohort Study.

BACKGROUND: Hand-transplantation and improvements in the field of prostheses opened new frontiers in restoring hand function in below-elbow amputees. Both concepts aim at restoring reliable hand function, however, the indications, advantages and limitations for each treatment must be carefully considered depending on level and extent of amputation. Here we report our findings of a multi-center cohort study comparing hand function and quality-of-life of people with transplanted versus prosthetic hands. METHODS: Hand function in amputees with either transplant or prostheses was tested with Action Research Arm Test (ARAT), Southampton Hand Assessment Procedure (SHAP) and the Disabilities of the Arm, Shoulder and Hand measure (DASH). Quality-of-life was compared with the Short-Form 36 (SF-36). RESULTS: Transplanted patients (n = 5) achieved a mean ARAT score of 40.86 ± 8.07 and an average SHAP score of 75.00 ± 11.06. Prosthetic patients (n = 7) achieved a mean ARAT score of 39.00 ± 3.61 and an average SHAP score of 75.43 ± 10.81. There was no significant difference between transplanted and prosthetic hands in ARAT, SHAP or DASH. While quality-of-life metrics were equivocal for four scales of the SF-36, transplanted patients reported significantly higher scores in "role-physical" (p = 0.006), "vitality" (p = 0.008), "role-emotional" (p = 0.035) and "mental-health" (p = 0.003). CONCLUSIONS: The indications for hand transplantation or prosthetic fitting in below-elbow amputees require careful consideration. As functional outcomes were not significantly different between groups, patient's best interests and the route of least harm should guide treatment. Due to the immunosuppressive side-effects, the indication for allotransplantation must still be restrictive, the best being bilateral amputees.

Assessing the outcome of hand and forearm allotransplantation using the Action Research Arm Test.

OBJECTIVE: The aims of this study were to apply for the first time the Action Research Arm Test for functional assessment of an allotransplanted upper extremity (hand or forearm), to describe any adaptations required to this test system for the abovementioned purpose, and to use this test to record any changes in outcome over time. DESIGN: A structured approach to the Action Research Arm Test was adopted including interrater and intrarater reliability assessment at the very beginning of its use and ongoing comprehensive monitoring of patients through regular checkups. Four male patients who had undergone hand or forearm allotransplantations, in the authors' center, were examined. All 19 items in the Action Research Arm Test were reviewed, and the total score was calculated, taking into account the given time limits for each item. RESULTS: All patients showed a marked clinical improvement in their test results over time. They continued to have difficulties with performing items in the pinch subtest. The intrarater and interrater assessment achieved consistent results. CONCLUSIONS: The data of this study indicate that the Action Research Arm Test is suitable for assessing the level of upper extremity function. The test can be used to compare functional outcomes after hand and forearm allotransplantation between different centers, providing objective information concerning the quality of reconstruction.

Neuromusculotendinous transfer: an original surgical concept for the treatment of drop foot with long-term follow-up.

BACKGROUND: An original surgical technique for the correction of drop foot is demonstrated. METHODS: Eighteen patients with drop foot underwent transfer of the lateral, medial, or both heads of the gastrocnemius muscle to the tendons of the anterior and/or lateral muscle group of the lower leg. The transferred muscle was reinnervated by nerve coaptation between the undamaged proximal part of the deep peroneal nerve and the motor branch of the tibial nerve supplying the gastrocnemius muscle. RESULTS: In all patients, the transferred gastrocnemius muscle showed signs of reinnervation within an average of 6 months after operation. Ten patients achieved excellent results, having regained stable, fully automatic walking without foot inversion/eversion and active range of foot movement of at least 40 degrees. Four patients achieved good results with active range of movement of less than 40 degrees but very stable functional gait. Satisfactory results were presented in three cases with stable ankle motion. Two of three cases had dual transfer of the gastrocnemius muscle and had a very stable ankle joint. In one fair case, the treatment improved stability and the patient was able to walk. CONCLUSIONS: To compensate for the loss of function of the anterior muscle compartment, neuromusculotendinous transfer of the gastrocnemius muscle has proved to be highly successful. Voluntary movement of the transferred muscle and fully automatic walking was achieved in the majority of patients treated. In contrast to the commonly used treatment of tibialis posterior muscle transfer, no reeducation of the transferred muscle was needed.

Microsurgical advances in extremity salvage.

The main goal of reconstructive microsurgery must be an optimal functional and esthetic reconstruction meeting the individual trauma site requirements with minimal donor site morbidity. The authors discuss new microsurgical options for extremity salvage: indications for reconstruction versus amputation, timing of free tissue transfer, reconstruction of soft tissue and bone, and functional muscle transfer. They discuss indications and contraindications for these procedures, along with emphasizing the important points of each.

The latissimus dorsi detrusor myoplasty for functional treatment of bladder acontractility.

Patients with bladder acontractility caused by lower motor neuron lesion are generally dependent on lifelong clean intermittent catheterization with all of its inherent risks. The functional neurovascular transfer of the latissimus dorsi muscle to the pelvis allows the restoration of voluntary voiding. This article describes the operative technique, indications, preoperative considerations, and postoperative care. The literature is reviewed and the latissimus detrusor myoplasty is compared with other functional muscle transfers to restore voluntary micturition.

The psychological assessment of candidates for reconstructive hand transplantation.

Standardized psychological assessment of candidates for reconstructive hand transplantation (RHT) is a new approach in transplantation medicine. Currently, international guidelines and standardized criteria for the evaluation are not established. Patients suffering from the loss of a hand or an upper extremity have to cope with multiple challenges. For a selected group of patients, RHT represents an option for restoring natural function and for regaining daily living independence. The identification of at-risk patients and those requiring ongoing counseling due to poor coping or limited psychological resources are the primary focus of the psychological assessment. We have developed the 'Innsbruck Psychological Screening Program for Reconstructive Transplantation (iRT-PSP)' which utilizes a semi-structured interview and standardized psychological screening procedures and continuous follow-up ratings. Between January 2011 and October 2011, four candidates were evaluated using the iRT-PSP. Psychological impairments including social withdrawal, embarrassment, reduced self-esteem, and a depressive coping style were identified and poor quality of life was reported. The motivation for transplantation was diverse, depending on many factors such as bi- or unilateral impairment, native or accidental loss of hand, and social integration.

Outcomes with respect to disabilities of the upper limb after hand allograft transplantation: a systematic review.

The aim of this work is to compare disabilities of the upper limb before and after hand allograft transplantation (HAT), and to describe the side effects of immunosuppressive (IS) agents given to recipients of hand allografts. Clinical cases of HAT published between 1999 and 2011 in English, French, or German were reviewed systematically, with emphasis on comparing disabilities of the arm, shoulder and hand (DASH) scores before and after transplantation. Duration of ischemia, extent of amputation, and time since amputation were evaluated for their effect on intrinsic musculature function. Infectious, metabolic, and oncological complications because of IS therapy were recorded. Twenty-eight patients were reported in 56 clinical manuscripts. Among these patients, disabilities of the upper limb dropped by a mean of 27.6 (±19.04) points on the DASH score after HAT (P = 0.005). Lower DASH scores (P = 0.036) were recorded after secondary surgery on hand allografts. The presence of intrinsic muscle function was observed in 57% of the recipients. Duration of ischemia, extent of transplantation, and time since amputation were not associated statistically with the return of intrinsic musculature function. Three grafts were lost to follow-up because of noncompliance with immunosuppression, rejection, and arterial thrombosis, respectively. Fifty-two complications caused by IS agents were reported, and they were successfully managed medically or surgically. HAT recipients showed notable functional gains, but most complications resulted from the IS protocols.

World experience after more than a decade of clinical hand transplantation: update on the Innsbruck program.

Patients who have lost a hand or upper extremity face many challenges in everyday life. For some patients, reconstructive hand transplantation represents a reasonable option for anatomic reconstruction, restoring prehensile function with sensation and allowing them to regain daily living independence. The first clinical case of bilateral hand transplantation at University Hospital Innsbruck was realized on March 17th, 2000. A decade later, a total of 7 hands and forearms were transplanted in 4 patients. This article review the clinical courses of 3 bilateral hand transplant recipients and highlights psychological aspects on reconstructive hand transplantation with special regard to unilateral/bilateral transplantation.

Functional outcome after hand and forearm transplantation: what can be achieved?

The first successful hand transplant in the modern era of reconstructive transplantation was performed in 1998. Since then, more than 65 hand and upper limb transplantations have been performed around the globe, with encouraging results. The main goal of all upper limb transplantations is to enhance the patient's quality of life. The transplant must be successfully integrated into the patient's body and self-image and the recipient should be satisfied with the recovery of sensitivity and muscle function of the new limb. To achieve these goals, a proper and thorough design of the rehabilitation regimen is of critical importance.

Lower lip reconstruction using a functioning gracilis muscle free flap.

The lips are highly visible structures on the face, providing oral competence and expressing emotion. The reconstruction of large full-thickness defects of the lips is a formidable challenge for the plastic surgeon. The most challenging defect of the lower lip is full thickness, larger than two thirds. Such an extensive defect requires either staged reconstruction or a flap of distant tissue. We consider that the gracilis muscle, due to its anatomic and functional features, is the ideal flap for reconstruction of the lips. A functioning gracilis matches all the requisites and allows normal movements that are uniform to all of the lip. The new commissure is symmetric and moves simultaneously with the residual commissure due to innervation by the facial nerve. Our indications to use the functioning gracilis muscle flap in lip reconstruction are as follows: resection of the lower lip larger than one quarter of the lip length in a patient younger than 60 years; resection larger than one third of the lip in all patients. When performing a free gracilis flap for lip reconstruction, we consider that, if possible, a facial artery musculomucosal flap and sensitive neurotization should be included to restore sensation of the reconstructed lip.

Lower lip reconstruction: introduction of a new procedure using a functioning gracilis muscle free flap.

BACKGROUND: Subtotal and total reconstruction of the lower lip is a challenge for the plastic surgeon: this lip mainly contributes to the continence function of the oral sphincter. Fasciocutaneous free flaps and local flaps are better suited to the skin laxity of elderly patients; furthermore, larger defects extending to the chin area can be difficult to manage with only local flaps. METHODS: In an attempt to restore very good function and aesthetics of the lower lip in a single procedure, the authors introduced the use of a functioning (innervated) gracilis free flap. The dynamic sphincter capacity was obtained with the coaptation between the motor branch of the gracilis muscle and the marginal branch of the facial nerve. A facial artery musculomucosal flap replaced the vermilion and the inner side mucosa, and a skin graft from the scalp covered the external surface of the gracilis. The procedure was performed in two cases. RESULTS: In both cases, the authors achieved quite full physiologic lower lip movement with regard to symmetrical spontaneous and voluntary controlled lower lip function, whereas the skin grafts from the scalp and the supraclavicular region had a nearly perfect color match with the reconstructed area. The aesthetic result was excellent compared with the complexity of the reconstructed defect. CONCLUSIONS: A functioning gracilis free flap has to be considered among the techniques for complex lower lip reconstruction. It was able to restore very good voluntary function and an extremely fine aesthetic result in a single-stage procedure.

Extracorporeal shock wave therapy in orthopaedic diseases.

The application of extracorporeal shock wave therapy (ESWT) as a treatment for different orthopaedic conditions has experienced a rapid increase over the last several years. However the mechanism of action and the therapeutic effect is not clear. The aim of this study was to review the literature about the efficacy of ESWT in the treatment of plantar fasciitis, lateral epicondylitis, shoulder painful disorders and non-union fractures. Only randomized controlled studies published in the last 5 years were retrieved from electronic database and manual search. Results on efficacy of ESWT are controversial. Studies that have claimed therapeutic benefit did not fulfill scientific criteria and controlled randomized trials were not able to confirm significant improvement after treatment with ESWT.

Self-reinforced bioabsorbable miniplates for skeletal fixation in complex hand injury: three case reports.

We report our preliminary experience with 3 cases in which internal fixation with a self-reinforced poly-l/dl-lactide 70/30 miniplate and 1.5-mm or 2.0-mm screws were used to stabilize an open metacarpal fracture, a metacarpophalangeal arthrodesis in a thumb replantation, and an interposed bone graft for reconstruction of a thumb. Clinical and radiologic follow-up evaluation lasted for 12 to 20 months. Bone healing was uneventful in all 3 cases with no displacement or delayed union. The implants were biocompatible with no clinically manifested foreign body reaction. Because of the self-reinforcing manufacturing technique the plates have metal-like mechanical and handling properties. Complete late resorption makes self-reinforced poly-l/dl-lactide 70/30 miniplating systems an attractive alternative to metallic implants for skeletal stabilization of small bones of the hand.

Anterior neck reconstruction with pre-expanded free groin and scapular flaps.

To improve aesthetic and functional outcomes in the reconstruction of severe anterior neck burn deformities and to reduce donor-site morbidity, pre-expansion of free-flap donor sites was performed in eight patients. In the first stage of reconstruction, the tissue expander was placed and gradually inflated over a period of 6 weeks. In the second stage, the anterior neck scar was resected up to the limits of the aesthetic unit of the neck, radical release of neck contracture was achieved by transection of contracted platysma muscle, and immediate coverage with a pre-expanded groin or scapular free flap was performed. The early postoperative course was uneventful. Physical therapy was started 1 week after the reconstruction. Long-term follow-up (mean, 4 years) of patients who underwent reconstruction of extensive neck burn deformities demonstrated good aesthetic and functional results. The advantages and drawbacks of using pre-expanded free flaps in the treatment of neck burn contractures are discussed.

Microsurgical management of the diabetic foot.

Allthough there has been dramatic progress in limb salvage in recent decades, management of nonhealing wounds in diabetic patients continues to present a dilemma for the reconstructive surgeon. However, the acceptance of free-flap resurfacing of diabetic foot ulcers has increased in recent years. This study reviews 10 microvascular free muscle flaps in nine patients over a mean follow-up period of 44 months. Five patients had evidence of peripheral vascular disease. There was one flap loss, and nine flaps were transferred successfully. No perioperative mortality was encountered. The operations required a long, costly hospitalization (average hospital stay was 40 days). Seven of eight patients whose flaps survived had complications related to the free-flap recipient site. These seven patients underwent 20 secondary surgical procedures due to arterial and venous thrombosis, partial necrosis of the skin grafts, minor local infections, and gangrene or necrosis of the remaining toes. In three patients, progressive ischemic necrosis of the remaining toes, with total survival of the flap, was attributed to a microvascular steal phenomenon. However, all eight patients whose flaps survived subsequently ambulated on their flaps. The study demonstrates that microvascular surgery may result in functional lower-extremity salvage in diabetic patients with foot wounds that are not treatable by local flaps or skin grafts, and are destined for amputation.
