RESUMEN

INTRODUCTION: Obesity is a risk factor for complications following autologous breast reconstruction. Little is known regarding outcomes based on the degree of obesity. This study compares breast reconstruction outcomes and complication rates for the three classes defined by the body mass index (BMI)-based WHO classification. METHODS: The authors conducted a retrospective chart review identifying obese patients who underwent abdominally based breast reconstruction between January 2011 and January 2021. Patients were stratified by BMI class [class 1 (C1) = 30-34.99 kg/m2, class 2 (C2) = 35-39.99 kg/m2, and class 3 (C3) = 40 kg/m2 + ]. Outcomes were compared. RESULTS: A total of 232 patients (395 flaps) were included with 138 patients were classified as C1, 68 patients as C2, and 26 patients as C3. Rates of any complication (80%) and at least one major complication (31%) did not vary significantly (P = 0.057, 0.185). Individual rates of 30-day readmission (18%) or reoperation (26%) did not vary significantly (P = 0.588 and 0.059). Rates of seroma (C1 = 15%, C2 = 16%, and C3 = 35%), hernia (C1 = 0%, C2 = 4%, and C3 = 8%), and incisional dehiscence (C1 = 30%, C2 = 44%, and C3 = 62%) were associated with significantly increased risk with higher classes of obesity (P < 0.05). The rate of flap failure did not vary significantly (P = 0.573). CONCLUSION: The risk of major complications and total flap loss associated with abdominally based breast reconstruction does not differ between the classes of obesity. Although complication rates are high overall in the obese population, detrimental complications do not vary between the classes. Patients should be counseled regarding their individual risk without the need for arbitrary BMI cutoffs.

RESUMEN

INTRODUCTION: Dupuytren's contracture is a connective tissue disease characterized by an abnormal proliferation of collagen in the palm and fingers, which leads to a decline in hand function because of progressive joint flexion. In addition to surgical and percutaneous interventions, collagenase clostridium histolyticum (CCH, trade name Xiaflex) is an intralesional enzymatic treatment for adults with palpable cords. The objectives of this study are to evaluate factors predictive of recurrence following treatment with CCH and to review the outcomes of repeat treatments with CCH for recurrent contracture. MATERIALS AND METHODS: An institutional review board-approved retrospective chart review was conducted for patients between 2010 and 2017 who received CCH injections for Dupuytren's contracture at a Veterans Affairs hospital. Demographics, comorbidities, affected finger and joint, pre/posttreatment contracture, time to recurrence, and treatment of recurrence were recorded. Successful treatment was defined as contracture ≤5° following CCH, and improvement was defined as ≥20° reduction from baseline contracture. Study cohorts were followed after their secondary treatment, and time to recurrence was recorded and plotted using a Kaplan-Meier curve. A Cox proportional hazards model was used to compare treatment group risk factors for recurrence with a P-value less than .05 defined as statistical significance. RESULTS: Of 174 injections performed for the correction of flexion deformities in 109 patients, 70% (121) were successfully treated with CCH, and an additional 20% (35) had improvement. There was a recurrence of contractures in 43 joints (25%). Of these, 16 contractures were treated with repeat CCH, whereas another 16 underwent limited fasciectomy. In total, 75% (12 of 16) of the repeat CCH group and 75% of the fasciectomy group were successfully treated. Pre-injection contracture of ≥25° was found to be predictive of recurrence (P < .05). CONCLUSIONS: Initial treatment of contracture with CCH had a 70% success rate with 25% recurrence during the study period. Compared with limited fasciectomy, CCH had decreased efficacy. Based on the findings of this study, we believe that the treatment of primary and/or recurrent Dupuytren's contracture with CCH is a safe and less invasive alternative to fasciectomy in the era of telemedicine. CCH treatment requires no suture removal, which allows the ability to assess motion virtually, and the potential consequences of CCH treatment such as skin tears can be assessed and managed conservatively. In the veteran and active duty population, CCH can facilitate faster recovery and return to service. Strengths of this study include a large series of veteran populations with longitudinal follow-up to determine treatment efficacy for primary Dupuytren's contracture and recurrence. Limitations include a smaller sample size compared to previous trials, a lack of standardized follow-up, and the retrospective nature of our study that prohibits randomization to compare outcomes between CCH treatment and fasciectomy efficacy over time. Directions for future research include stratification of patients by joint and specific digit involvement as well as comparison with percutaneous needle fasciotomy, another minimally invasive technique that could benefit the veteran population at increased risk for developing Dupuytren's disease.

RESUMEN

INTRODUCTION: Pyoderma gangrenosum (PG) is a relatively uncommon necrotizing and ulcerative cutaneous disorder. It is often associated with a systemic inflammatory disease but may also present following trauma to the skin due to pathergy. Given its rare occurrence and nonspecific histology, PG is primarily a diagnosis of exclusion, which often results in delayed treatment. Very few cases of PG following autologous breast reconstruction have been reported in the literature, particularly in the absence of systemic disease. CASE REPORT: Presented is the case of a 62-year-old female with a history of ductal carcinoma in situ who underwent a left breast mastectomy with immediate deep inferior epigastric perforator flap breast reconstruction complicated by fever and leukocytosis as well as erythema, edema, and bullae involving the mastectomy flaps. Initially, necrotizing soft-tissue infection was suspected, and 2 debridements were performed. A diagnosis of PG was made on postoperative day 7, and the patient responded favorably to high-dose prednisone. Reconstruction was performed with a bilayer wound matrix and delayed skin grafting. Despite significant loss of mastectomy skin flap, the free flap was preserved. CONCLUSIONS: Although PG is a rare complication, it should be considered in the differential diagnosis for patients with atypical presentation of infection following breast reconstruction, even in the absence of systemic inflammatory disease. Early diagnosis and multidisciplinary management may prevent unnecessary surgical intervention and enable flap preservation. Furthermore, bilayer wound matrix placement may be useful as an intermediate reconstruction to determine if it is safe to proceed with skin grafting to avoid further pathergy. The findings in this case suggest that final reconstruction may be safely performed sooner than noted in the literature.

RESUMEN

BACKGROUND: In the United States, approximately 30% of about 10,000 annual blast injuries involve the hand, causing a broad spectrum of injury severity. The first web space is typically most severely affected. As the carpometacarpal (CMC) joint is critical to the unique function of the thumb, we evaluated typical patterns of injury to this joint, subsequent salvageability and functional outcomes of the thumb. METHODS: We conducted a retrospective chart review on patients with blast injuries to the hand from January 1995 through July 2019 and excluded penetrating trauma. We assessed hand function as reported in occupational therapy records. Injury severity was classified independently by structures. RESULTS: Twenty-one patients were included, two with bilateral injuries, for a total of 23 hands. Eighteen patients had injuries to one or both thumbs, for a total of 20 thumbs evaluated. Average follow-up was 1.58 years. Most injuries qualified as severe in at least one category: soft tissue, neurovascular, or bone/joint. All 10 CMC joint dislocations required surgical fixation and pinning. Eight patients had applicable occupational therapy notes available. Severely injured thumbs had statistically significant decreased range of motion (ROM) at the interphalangeal joint, metacarpophalangeal joint and with radial abduction compared to mildly injury thumbs (P value 0.02, 0.03, 0.04, respectively). CONCLUSIONS: Blast injury to the hand often results in severe deficits, frequently affecting thumb functionality and irreversibly altering occupational capabilities. Half the patients studied had severe damage to the thumb CMC joint. Objectively, severely injured thumbs had significantly worse ROM than mildly injured thumbs.

RESUMEN

Targeted muscle reinnervation (TMR) has been shown to improve phantom and neuropathic pain in both the acute and chronic amputee population. Through rerouting of major peripheral nerves into a newly denervated muscle, TMR harnesses the plasticity of the brain, helping to revert the sensory cortex back toward the preinsult state, effectively reducing pain. We highlight a unique case of an above-elbow amputee for sarcoma who was initially treated with successful transhumeral TMR. Following inadvertent nerve biopsy of a TMR coaptation site, his pain returned, and he was unable to don his prosthetic. Revision of his TMR to a more proximal level was performed, providing improved pain and function of the amputated arm. This is the first report to highlight the concept of secondary neuroplasticity and successful proximal TMR revision in the setting of multiple insults to the same extremity.

RESUMEN

BACKGROUND: Cosmetic surgery tourism is increasing exponentially. Patients seek cosmetic procedures within the United States and abroad, lured by lower cost procedures, shorter waiting lists, and affordable airfare and hotel accommodations. Unfortunately, operations are often performed by non-board-certified plastic surgeons, sometimes not even by plastic surgeons. Preoperative counseling, frequently limited to a video-chat with an office secretary, provides inadequate discussion regarding potential complications. Postoperative care is careless and rarely involves the operating surgeon. Complications are frequent, with management falling into the hands of plastic surgeons unfamiliar with the patient's care. Furthermore, the physician, rather than the patient or hospital, faces the largest cost burden. OBJECTIVES: The authors sought to explore their institution's experience treating complications of cosmetic tourism and investigate associated costs. METHODS: The retrospective review of 16 patients treated for complications related to cosmetic surgery tourism plus cost analysis revealed a substantial discrepancy between money saved by undergoing surgery abroad and massive costs accrued to treat surgical complications. RESULTS: The most common complication was infection, often requiring surgery or IV antibiotics on discharge. Mean cost per patient was $26,657.19, ranging from $392 (single outpatient visit) to $154,700.79 (prolonged admission and surgery). Overall, the hospital retained 63% of billed charges, while physicians retained only 9%. The greatest amount paid by any single patient was $2635.00 by a patient with private insurance. CONCLUSIONS: Cosmetic tourism has severe medical repercussions for patients and complications that burden hospitals, physicians, and the US medical system. Physicians treating the complications suffer the greatest financial loss.

RESUMEN

INTRODUCTION: Serratia marcescens is a facultative anaerobic bacillus that very rarely causes sternal infections. We describe a sternal abscess resulting from chronic S. marcescens infection that presented 13 years after coronary artery bypass graft surgery (CABG). PRESENTATION OF CASE: A 71-year-old diabetic man presented 13 years after CABG with a new distal sternal "mass" that intermittently drained purulent fluid. He was treated with oral antibiotics, but the symptoms persisted. Exploration revealed an abscess extending to the sternal body. A non-absorbable braided suture and a sternal wire were removed, but a sinus tract remained despite further antibiotics and conservative care. Subsequent computed tomography and bone scintigraphy revealed a substernal soft tissue density with bone involvement. An abscess cavity was excised from the substernal anterior mediastinum. Another non-absorbable braided suture was removed. Cultures grew carbapenem-resistant S. marcescens. DISCUSSION: Nosocomial or hospital-associated clusters of S. marcescens infection are known, but isolated infections seldom occur. S. marcescens infections in cardiac surgery patients are unusual. Only a single report described a chronic sternal infection resulting from S. marcescens that was identified 15 years after an initial episode caused by the same organism in a heart transplant recipient who was immunocompromised. Diabetes and non-absorbable braided sutures placed for hemostasis at the wire sites were probably contributing factors to our patient's chronic infection. CONCLUSION: This report described the presentation and treatment of a chronic S. marcescens sternal abscess that occurred 13 years after CABG. Chronic sternal infections due to this organism in cardiac surgery patients are exceeding rare.

RESUMEN

BACKGROUND: Proximally based, pedicled flexor carpi ulnaris (FCU) muscle flap has been described previously for soft tissue coverage of the proximal forearm and elbow. No studies have been done on the distal muscular perforators and its use as a distally based flap. METHODS: Ten fresh-frozen cadaveric dissections were done. Specimens were injected with latex to facilitate identification of the perforators. Distal muscular perforators were dissected and distances of the pedicles from the distal wrist crease and ulnar styloid were measured and recorded. A clinical case is also presented where a distally based FCU muscle flap was used for coverage in a patient with median nerve neuroma. RESULTS: A distal muscular perforator and a second more proximal perforator were identified in all specimens. The average distance from the most distal muscular perforator to the ulnar styloid was 3.0 cm. The average distance to the wrist crease was 4.6 cm. The more proximal perforators had an average distance to the ulnar styloid and wrist crease of 7.3 cm and 8.8 cm, respectively. At 7 months post-op, the patient who underwent median nerve neurolysis and coverage with pedicled FCU flap had much improved sensation, with complete resolution of pain and tingling, and without any functional deficits. CONCLUSIONS: The use of a distally based FCU muscle flap is a good option for soft tissue coverage of the distal forearm, wrist, and hand. The distal muscular perforators from the ulnar artery exhibit a relatively consistent anatomy.

RESUMEN

Background: Cubital tunnel syndrome is a common compressive neuropathy of the upper extremity. The anconeus epitrochlearis muscle is an unusual but occasional contributor. We review our experience with this anomalous muscle in elbows with cubital tunnel syndrome. Methods: We retrospectively reviewed charts of 13 patients noted to have an anconeus epitrochlearis muscle associated with cubital tunnel syndrome. Results: Ten patients had unilateral ulnar neuropathy supported by nerve conduction studies. Three had bilateral cubital tunnel syndrome symptoms with 1 of those having normal nerve conduction studies for both elbows. Eight elbows were treated with myotomy of the anconeus epitrochlearis muscle and submuscular transposition of the ulnar nerve. The other 8 elbows were treated with myotomy of the anconeus epitrochlearis muscle and in situ decompression of the ulnar nerve only. All but 1 patient had either clinical resolution or improvement of symptoms at follow-up ranging from 2 weeks to 1 year after surgery. The 1 patient who had persistent symptoms had received myotomy and in situ decompression of the ulnar nerve only. Conclusions: An anomalous anconeus epitrochlearis occasionally results in compression of the ulnar nerve but is usually an incidental finding. Its contribution to compression neuropathy can be tested intraoperatively by passively ranging the elbow while observing the change in vector and tension of its muscle fibers over the ulnar nerve. Regardless of findings, we recommend myotomy of the muscle and in situ decompression of the ulnar nerve. Submuscular transposition of the ulnar nerve may be necessary if there is subluxation.

RESUMEN

BACKGROUND: Lipomas are common benign tumors. When they develop in proximity to peripheral nerves, they can cause neurologic symptoms secondary to mass effect. Previous reports have shown symptom resolution after removal of lipomas compressing various upper extremity peripheral nerves. However, brachial plexus lipomas are relatively rare. Our multidisciplinary experience with brachial plexus lipoma resection is reviewed in the largest case series to date. METHODS: A retrospective chart review of all patients undergoing resection of brachial plexus lipomatous tumors between 2006 and 2016 was performed. Patient demographic data, diagnostic imaging, clinical presentation, operative details, surgical pathology, and clinical outcomes were reviewed. RESULTS: Twelve brachial plexus lipomatous tumors were resected in 11 patients: 10 lipomas, 1 hibernoma, and 1 atypical lipomatous tumor. The most common tumor location was supraclavicular (50%), followed by axillary (42%), and proximal medial arm (8%). The most common brachial plexus segment involved was the upper trunk (50%), followed by posterior cord (25%), lateral pectoral nerve (8%), lower trunk (8%), and proximal median nerve (8%). Most patients presented with an enlarging painless mass (58%). Of the patients who presented with neurologic symptoms, symptoms resolved in the majority (80%). CONCLUSIONS: Brachial plexus lipomas are rare causes of compression neuropathy in the upper extremity. Careful resection and knowledge of brachial plexus anatomy, which may be distorted by the tumor, are critical to achieving a successful surgical outcome with predictable symptom resolution. Finally, surveillance magnetic resonance imaging may be warranted for atypical lesions.

RESUMEN

Although several donor nerves can be chosen to repair avulsed brachial plexus nerve injury, available nerves are still limited. The purpose of this study is to validate whether the vagus nerve (VN) can be used as a donor. Eighteen Sprague-Dawley male rats were divided into three groups (n = 6). The right musculocutaneous nerve (McN) was transected with differing subsequent repair. (1) HS-VN group: a saphenous nerve (SN) graft-end was helicoidally wrapped round the VN side (epi-and perineurium was opened) with a 30 ° angle, distal SN end was coapted to the McN with end-to-end repair. (2) EE-PN group: a SN was interpositionally grafted between the transected phrenic nerve (PN) and the McN by end-to-end coaptation. (3) Sham control group: McN was transected and not repaired and postoperative vital signs were checked daily. At three months, electrophysiology, tetanic force, wet biceps muscle weight, and histology were evaluated. Every tested mean value in HS-VN group was significantly greater than the EE-PN or the sham control groups (p < 0.05 or p < 0.005). The mean recovery ratio of regenerated nerve fibers was 96% and, in HS-VN group, the mean recovery ratio of CMAP was 79%. No vital signs changed in any group. There was no statistical difference (p > 0.5) between the mean VN nerve-fiber numbers of the segments proximal (2237 ± 134) and distal (2150 ± 156) to the VN graft-attachment site. Histological analysis revealed no axon injury or intraneural scarring at any point along the VN. This study demonstrated that VN is a practical and reliable donor nerve for end-to-side nerve transfer. © 2017 Wiley Periodicals, Inc.

RESUMEN

Heterotopic ossification (HO) is widely recognized as a common occurrence among patients suffering from traumatic spinal cord injuries (SCI). The exact etiology of HO formation remains unknown. Published medical and surgical management strategies are often plagued with questionable effectiveness and frequent complications. There are minimal publications regarding the management strategies of HO in SCI patients as it pertains to plastic surgery. We present a case series of patients treated at our institution who underwent treatment for pressure ulcers with underlying HO to highlight the vast spectrum of clinical phenotypes present in this population. The pathophysiology, diagnostic tools, methods of prevention, and surgical management of HO are discussed here. We believe that there are two clinically relevant patterns of HO in SCI patients. A neurogenic process that occurs early after injury is usually bilateral and involves uninjured hip joints. Pressure sores that occur are related to poor joint mobility and subsequent development of pressure points. An infection-driven process in which HO development is associated with either pressure sores or septic hip joints is generally unilateral and not always associated with hip contractures. They present different challenges and reconstructive options to plastic surgeons. Although complications such as infection and HO recurrence are common, the functional and psychological benefits of restoring hip flexion are usually worthwhile.

RESUMEN

BACKGROUND: The shape of the deep cervical structures is the shape of an aesthetic neck. With age, changes can obstruct visualization of that shape. Achieving a youthful contour requires removal of excess skin and fat but also control of the platysma to allow skin to redrape like a blanket over an underlying framework. The authors' technique makes the platysma part of the deep cervical structures whose shape underlies an attractive neck and allows the skin to redrape to that contour. METHODS: To make the platysma conform closely to the deep cervical structures and allow the skin to show that new form, the authors developed a procedure that includes removal of excess fat, attaching the platysma to the hyoid fascia, approximating the edges of the platysma above and below that suture, and wide undermining of skin to allow it to re-drape naturally over those deeper structures. RESULTS: Over 7 years, 110 patients underwent aesthetic facial surgery that included hyoid suspension of the platysma. One patient had recurrence of platysmal bands after failure of the key suture. Complications included hematoma in three patients and submental seromas in three patients, but no permanent nerve injury, no skin loss from vascular compromise, no reported changes in vocal resonance, and no complaints of difficulty swallowing. CONCLUSIONS: This method allows the skin to redrape over a youthful framework and produces reliable aesthetic and long lasting results. It is a simple, reproducible, teachable technique that enables surgeons to achieve results previously difficult to obtain in a single operation. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

RESUMEN

BACKGROUND: Insidious cumulative brain injury from motor vehicle-induced whole-body vibration (MV-WBV) has not yet been studied. The objective of the present study is to validate whether whole-body vibration for long periods causes cumulative brain injury and impairment of the cerebral function. We also explored a preventive method for MV-WBV injury. METHODS: A study simulating whole-body vibration was conducted in 72 male Sprague-Dawley rats divided into 9 groups (N = 8): (1) 2-week normal control; (2) 2-week sham control (in the tube without vibration); (3) 2-week vibration (exposed to whole-body vibration at 30 Hz and .5 G acceleration for 4 hours/day, 5 days/week for 2 weeks; vibration parameters in the present study are similar to the most common driving conditions); (4) 4-week sham control; (5) 4-week vibration; (6) 4-week vibration with human apolipoprotein A-I molecule mimetic (4F)-preconditioning; (7) 8-week sham control; (8) 8-week vibration; and (9) 8-week 4F-preconditioning group. All the rats were evaluated by behavioral, physiological, and histological studies of the brain. RESULTS: Brain injury from vibration is a cumulative process starting with cerebral vasoconstriction, squeezing of the endothelial cells, increased free radicals, decreased nitric oxide, insufficient blood supply to the brain, and repeated reperfusion injury to brain neurons. In the 8-week vibration group, which indicated chronic brain edema, shrunken neuron numbers increased and whole neurons atrophied, which strongly correlated with neural functional impairment. There was no prominent brain neuronal injury in the 4F groups. CONCLUSIONS: The present study demonstrated cumulative brain injury from MV-WBV and validated the preventive effects of 4F preconditioning.

RESUMEN

A 20-year-old male was evaluated for winging of the scapula and an enlarging axillary mass of 4 months' duration. Imaging demonstrated a multiloculated cystic lesion that extended into the axilla and superiorly displaced the brachial plexus and axillary vessels surrounding an exostotic mass arising from the scapula. Surgery confirmed the mass to be a benign osteochondroma with a reactive bursa. The long thoracic nerve was intact and the serratus anterior muscle contracted normally with nerve stimulation. The scapular winging resolved completely following resection of the osteochondroma, and shoulder and arm function remained normal. A literature review of causes of pseudo-winging of the scapula was performed. Scapular osteochondroma is a rarely reported cause of scapula winging.

RESUMEN

Insidious brain microinjury from motor vehicle-induced whole-body vibration (WBV) has not yet been investigated. For a long time we have believed that WBV would cause cumulative brain microinjury and impair cerebral function, which suggests an important risk factor for motor vehicle accidents and secondary cerebral vascular diseases. Fifty-six Sprague-Dawley rats were divided into seven groups (n = 8): 1) 2-week normal control group, 2) 2-week sham control group (restrained in the tube without vibration), 3) 2-week vibration group (exposed to whole-body vibration at 30 Hz and 0.5g acceleration for 4 hr/day, 5 days/week, for 2 weeks), 4) 4-week sham control group, 5) 4-week vibration group, 6) 8-week sham control group, and 7) 8-week vibration group. At the end point, all rats were evaluated in behavior, physiological, and brain histopathological studies. The cerebral injury from WBV is a cumulative process starting with vasospasm squeezing of the endothelial cells, followed by constriction of the cerebral arteries. After the 4-week vibration, brain neuron apoptosis started. After the 8-week vibration, vacuoles increased further in the brain arteries. Brain capillary walls thickened, mean neuron size was obviously reduced, neuron necrosis became prominent, and wide-ranging chronic cerebral edema was seen. These pathological findings are strongly correlated with neural functional impairments.

RESUMEN

Spindle cell lipomas (SCL) are benign, slow growing tumors arising most frequently in the subcutaneous tissue of the upper back, posterior neck, and shoulders in males aged 40-70 years. Local excision is generally curative. Classification of lipomatous tumors has progressed recently, and tumors of similar morphology and unusual presentation are increasingly reported, thereby making correct diagnosis even more vital. SCL require pathologic differentiation from liposarcoma, other spindle cell neoplasms, and myxoid lesions for treatment purposes. Cytology, histology, and cytogenetics, in conjunction with clinical presentation, are paramount in arriving at the correct diagnosis of spindle cell lipoma. We present a case report with characteristics typical of an SCL along with a literature review to further elucidate the diagnosis and surgical treatment of this soft tissue tumor.

RESUMEN

INTRODUCTION: After nerve injury, excessive calcium impedes nerve regeneration. We previously showed that calcitonin improved nerve regeneration in crush injury. We aimed to validate the direct effect of calcitonin on transected and repaired nerve. METHODS: Two rat groups (n = 8) underwent sciatic nerve transection followed by direct repair. In the calcitonin group, a calcitonin-filled mini-osmotic pump was implanted subcutaneously, with a catheter parallel to the repaired nerve. The control group underwent repair only, without a pump. Evaluation and comparison between the groups included: (1) compound muscle action potential recording of the extensor digitorum longus (EDL) muscle; (2) tetanic muscle force test of EDL; (3) nerve calcium concentration; and (4) nerve fiber count and calcified spot count. RESULTS: The calcitonin pump group showed superior recovery. CONCLUSIONS: Calcitonin affects injured and repaired peripheral nerve directly. The calcitonin-filled mini-osmotic pump improved nerve functional recovery by accelerating calcium absorption from the repaired nerve. This finding has potential clinical applications.

RESUMEN

BACKGROUND: Historically, the mainstay of soft-tissue reconstruction in the groin and lower abdomen has been the anatomically consistent, easily elevated rectus abdominis flap, with variations. Insetting the rectus abdominis flap here requires creating an abdominal wall defect through which to pass the pedicle, which raises the risk of donor-site morbidity. Although popular as a free flap, the anterolateral thigh flap as a pedicled flap in the groin and lower abdomen has not been directly compared with the rectus abdominis flap. METHODS: Retrospective record review was conducted on 39 patients who underwent groin or lower abdominal wall reconstruction (30 anterolateral thigh flap and 10 rectus abdominis flap procedures) to address oncologic defects, lymphadenectomy, and complications of vascular bypass. Patient demographics and comorbidities, flap characteristics, postoperative complications, and time to heal were compared. RESULTS: All patients in both the anterolateral thigh and rectus abdominis flap groups healed at the flap recipient sites. Despite similar patient characteristics, wound cause was different between the groups, with more infected wounds being treated in the anterolateral thigh flap group. Early postoperative complication rates were similar in both groups. Anterolateral thigh flap patients had shorter time to healing, with lower rates of delayed (>30 days) postoperative complications compared with rectus abdominis flap patients. Six rectus abdominis flap patients developed delayed abdominal incisional hernias. No donor- or recipient-site complications were encountered in anterolateral thigh flap patients after 90 days. CONCLUSION: The pedicled anterolateral thigh flap is the preferred choice for reconstruction of wounds in the groin and lower abdomen.

RESUMEN

BACKGROUND: A Marjolin's ulcer describes malignant degeneration in any chronic wound. The majority of cases arise in burn scars and are often latent for decades. MATERIALS AND METHODS: This case series presents 6 patients with an average age of 63 years with Marjolin's ulcers (both acute and chronic). A review of the literature was also undertaken. These cases underscore the aggressive course and poor prognosis associated with Marjolin's ulcers and the importance of recognizing the potential for malignant transformation of a chronic wound. RESULTS: In the reported cases, the ulcers were found on the upper and lower extremity, flank, and over the sacrum, emphasizing the propensity of these ulcers to arise in nearly any location. Squamous cell carcinoma is the most prevalent malignancy identified in Marjolin's ulcers and was confirmed in all patients in this study. Patients underwent surgical resection, and all patients eventually succumbed to the disease. CONCLUSION: Based on observations and a review of the literature, early detection and aggressive management with wide local excision and prompt coverage yield optimal results when treating patients with Marjolin's ulcers.
