Safe osteocutaneous radial forearm flap harvest with prophylactic internal fixation.

ABSTRACT: We studied the efficacy of prophylactic plate fixation technique and a modified harvest of the osteocutaneous radial forearm free flap (OCRFFF) to minimize the incidence of postoperative donor radius pathological fracture. We retrospectively studied of the first 70 consecutive patients undergoing OCRFFF harvest by the University of Kansas Head and Neck Microvascular Reconstruction Team. Mean follow-up was 13 months. One of two patients undergoing OCRFFF harvest without prophylactic fixation developed a pathological radius fracture. The 68 subsequent OCRFFF patients underwent prophylactic fixation of the donor radius, and none developed a symptomatic radius fracture. Five of 68 patients did have a radiographically visible fracture requiring no intervention. The plate fixation technique was further modified to exclude monocortical screws in the radius bone donor defect (subsequent 39 patients), without any further fractures detected. One patient required forearm hardware removal for an attritional extensor tendon tear. The described modified OCRFFF harvest and prophylactic plate fixation technique may eliminate postoperative pathological fracture of the donor radius. Donor morbidity is similar to that of the fasciocutaneous radial forearm free flap , affording safe use of OCRFFF in head and neck reconstruction.

Reverse radial forearm fascial flap with radial artery preservation.

Project description:The reverse radial forearm fascial (RRFF) flap is widely used in soft-tissue reconstruction of the hand. The traditional RRFF flap incorporates the radial artery from the forearm and is perfused by retrograde flow through the palmar arch. In patients with an abnormal Allen test because of an incomplete palmar arch, the traditional RRFF flap is contraindicated unless a vein graft is used to reconstruct the radial artery. A simpler alternative approach for hand reconstruction in such patients is a distally based RRFF flap based on radial artery perforators, which preserves the radial artery. We used RRFF flaps based on radial artery perforators in five patients who had palmar or dorsal soft-tissue loss. All five recovered full hand function, and only one had any complications (full-thickness skin graft loss at recipient site). The RRFF flap based on distal radial artery perforators is suitable for thin coverage of soft-tissue defects in hands with either a complete or an incomplete palmar arch.

Reverse radial forearm flap peforator used in digital revascularization.

Project description:There are very few reports in the literature of using pedicled flaps to revascularize distant tissue. Here, we describe the first description of using a radial artery perforator from a reverse radial forearm flap to revascularize a digit. Complex hand trauma presents multifaceted problems for the surgeon. This is illustrated by a recent case we treated of a severe hand crush injury, in which the two main problems were finger devascularization and a palmar defect. This required vein graft revascularization and local flap reconstruction. The initial management failed, and instead of repeating the same procedures, a single elegant solution was found. A reversed radial forearm flap was used for soft tissue defect coverage of the palmar defect, while a radial artery perforator was isolated for digital revascularization. This technique may seem excessive for digital revascularization, but in the correct context it overcomes "zone of injury" issues in major hand trauma and allows simultaneous revascularization with soft tissue defect cover.

Resurfacing of a Degloved Finger With a Reverse Radial Adipofascial Forearm Flap.

Project description:Complex upper-limb trauma, in particular crush and avulsion injuries, present an ongoing challenge for the reconstructive hand surgeon given the extensive zone of injury, particularly involving the neurovascular structures. When replantation is deemed unsuitable, the reconstruction must be both robust and flexible enough to meet the functional needs of the patient. The authors present a case of a ring avulsion amputation of the middle digit of a young patient's dominant hand. Due to the distal extent of avulsion, the amputated digit was determined to be nonreplantable, and the patient's medical comorbidities precluded traditional delayed pedicle flap options. Therefore, a reverse radial adipofascial flap was used as a single-stage reconstruction to resurface the entirety of the circumferential digital defect. At 8 months of follow up, the patient demonstrated exceptional passive and active range of motion with excellent contour and cosmesis, illustrating the utility of this reconstructive option.

Radial forearm free flap in a patient with an unusual radial artery variation: a case report.

Project description:Head and neck reconstruction poses unique challenges in rehabilitating surgical defects in terms of integrity, function, and form. The radial forearm free flap (RFFF) has been widely used for defect coverage, especially in the head and neck area, but its versatility allows it to be used for soft-tissue reconstruction in various parts of the body. The vascular features of the flap are quite constant and reliable. Nevertheless, abnormalities of the forearm vascular tree have been described over the decades. We report a case of intraoral reconstruction after verrucous carcinoma recurrence in a 74-year-old woman with an unusual forearm flap, which we called the median forearm free flap, based on a median branch of the radial artery that was preoperatively detected using handheld Doppler ultrasonography. The distally located skin paddle was predominantly supplied by the aberrant median vessel with its perforators. The flap was thus safely harvested with this atypical pedicle. Successful reconstruction of the intraoral defect was achieved, with an uneventful postoperative course.

Management of radial artery pseudoaneurysm in radial forearm free flap: case report and review of the literature.

Project description:The formation of a pseudoaneurysm in a revascularized free flap is an extremely rare complication in microsurgery. The most effective treatment modality is still the subject of debate. We present the management of a case of pseudoaneurysm of the arterial pedicle of a radial free flap used after hemiglossopelvectomy in a patient with squamous cell carcinoma of the tongue. In our case, a 74-year-old man with the pseudoaneurism was successfully treated by endovascular stenting. Endovascular stenting can be considered an effective and safe procedure and a relevant alternative to open neck surgical treatment.

Double-layered collagen graft to the radial forearm free flap donor sites without skin graft.

Project description:Radial forearm free flap is the most reliable flap for intraoral soft tissue reconstruction after cancer ablation surgery. However, unesthetic scar of the donor site and the need for a second donor site for skin graft are major disadvantages of the forearm flap. The purpose of this study was to report the clinical results of double-layered collagen graft to the donor site of the forearm free flap without skin graft.Twenty-two consecutive patients who underwent oral cancer ablation and forearm reconstruction between April 2010 and November 2013 were included in this study. Male to female ratio was 12:10, and average age was 61.0 years old (27-84). Double-layered collagen was grafted to the donor site of the forearm free flap and healed for secondary intention. Upper silicone had been trimmed at the periphery during secondary intention, and dry dressing was used. Postoperative scar healing and esthetic results and function were evaluated.An average follow-up period was 34.9 months. The scar area was decreased to 63.9 % in average. The complete healing was obtained between 1.5 and 3 months according to the defect size. There was no functional defect or impairment 3 months after operation. All patients were satisfied with the esthetic results. Three patients died of recurred cancer.Double-layered collagen graft was successfully performed in this study. Without the thigh skin graft, patients had experienced less painful postoperative healing periods and discomfort.

Single Superficial versus Dual Systems Venous Anastomoses in Radial Forearm Free Flap: A Meta-Analysis.

Project description:BackgroundThe radial forearm free flap (RFFF) has been widely used with increasing frequency in head and neck reconstruction following extirpative surgery. The controversy of the venous anastomoses patterns still exists. Thus, we conducted a meta-analysis to assess the relationship between the venous anastomoses patterns and venous compromise.MethodsMEDLINE, PubMed, Web of Science, and Wanfang databases were searched for studies reporting the different venous anastomoses patterns of the RFFF. A meta-analysis was conducted using the random effects models. Publication bias and sensitivity analysis were also assessed.Results6 studies with 992 cases were included in this meta-analysis. The dual anastomosis group tended to have a lower incidence of venous compromise (RR = 1.39). However, the difference was not statistically significant (95%CI: 0.59, 3.24).ConclusionsThis meta-analysis indicated that performing dual venous anatomoses consisting of superficial and deep systems conferred a tendency of the reduction with regard to venous compromise.

Wound botulism complicating internal fixation of a complex radial fracture.

Project description:Botulism developed in a patient following surgical repair of an open radial fracture. Symptoms resolved after treatment with antitoxin and antibiotics, and hardware excision was deferred. Subsequent osteomyelitis necessitated hardware exchange, and wound cultures grew Clostridium argentinense. This case highlights the management of botulism associated with orthopedic hardware.

Long-term functional donor site morbidity of the free radial forearm flap in head and neck cancer survivors.

Project description:BackgroundTo assess the functional donor site morbidity of the forearm free flap in patients surviving at least 2 years after ablative head and neck cancer surgery in a tertiary care centre.MethodsThis study involved nine long-term survivors (2 year post-operative) who had forearm free flaps to reconstruct head and neck defects. All flaps were raised from the non-dominant arm. The non-donor side acted as a control for all patients. Objective measurements were as follows: grip, tip pinch and key pinch strength measured with dynamometers; flexion, extension, radial and ulnar deviation and pronation and supination range of motion at the wrist measured with goniometry; A timed manual dexterity task was performed with a grooved pegboard test, and sensation of the radial nerve was tested with Semmes Weinstein monofilaments. Subjective measurements included a validated patient questionnaire of hand function and opinions of scar appearance as well as a validated scar assessment from two different observers.ResultsPronation at the wrist, manual dexterity and sensation were found to be significantly reduced in the donor side compared to the non-donor side. Inter-rater agreement between the two observers was found to be poor, except for an acceptable correlation between overall scar opinions. No correlations were found between any subjective or objective items or between the patient's and the observers' subjective evaluations.ConclusionsDonor site morbidity can be demonstrated with objective testing however this is accepted and well tolerated by head and neck cancer patients.

Donor site morbidity of the fasciocutaneous radial forearm flap: what does the patient really bother?

Project description:The objective of this study was the evaluation of donor site morbidity in head and neck cancer patients after reconstruction using a free vascularized radial forearm flap with emphasis on subjective complaints. Fifty patients who underwent at least 6 months before a reconstruction using a free vascularized radial forearm flap were asked to fill out two questionnaires regarding cosmetics and sensibility and forearm disabilities. Furthermore, a function test including movement extensions (flexion-extension, ulnar-radial deviation and pronation-supination), strength (pinch and grip) and temperature (digiti I and V) of the donor and non-donor site were measured and compared. Thirty-five percent of the patients reported no complaints regarding cosmetics and sensibility and 75% mentioned no forearm disabilities. There was no difference in movement extensions, temperature and grip strength between donor and non-donor sites. The difference in pinch strength appeared to be significant (p < 0.001). The total score of the questionnaire on forearm disabilities correlated significantly with extension, pronation and grip strength of the donor arm. Donor site morbidity of the radial forearm flap measured by objective functional tests was limited but subjective self-ratings revealed complaints regarding cosmestics and sensibility and to a lesser extent regarding forearm disability. The present data may be used for solid patient counselling.
