An Algorithmic Approach to the Suspected Septic Wrist.

An acutely painful, erythematous wrist can be due to a variety of pathologic processes, including crystalline arthropathy, infection, trauma, osteoarthritis, and systemic disease. The broad differential diagnosis of the inflamed wrist and nonspecific clinical findings make accurate diagnosis challenging. There is no published clinical or laboratory criterion that reliably differentiates septic wrist arthritis from a sterile inflammatory arthropathy. For septic joint patients, long-term results are notably poorer in patients with a delay in treatment, therefore establishing evidenced-based guidelines deserves attention.After a comprehensive literature review, we present evidenced-based guidelines and an algorithm for the management of the patient with an acutely inflamed wrist concerning for septic arthritis.For determining a diagnosis, systemic blood laboratory results are extremely variable and unreliable. Despite the attention given to the diagnostic potential of synovial fluid tests, the literature consistently demonstrates that diagnostic certainty cannot always be ascertained at the time of presentation based on aspiration fluid samples. Additionally, the investigative work does not necessarily end at the discovery of crystals since concomitant infection is a rare but well reported entity.Relative to larger joints, the wrist is far less likely to be infected and is easier to drain of debris, and therefore the empiric management of an inflamed wrist joint should reflect these differences. For treatment of the suspected or confirmed septic wrist, prompt initiation with appropriate antibiotics and drainage of joint purulence is critical to rapid recovery. However, the best strategy to clear the joint space of infectious material is controversial. Although the traditional standard of care is open drainage of a septic joint, a growing body of literature supports that for a septic wrist joint, a less invasive approach with serial aspiration can be equally efficacious with reduced morbidity and quicker recovery. If the wrist fails to improve with daily aspirations, then arthroscopy or open washout is needed.For patients with suspected wrist joint infection or crystalline arthropathy with probable concomitant infection, a reasonable approach is admission for systemic antibiotics and daily arthrocentesis. If the wrist fails to improve or worsens, then surgical treatment may be pursued. This treatment strategy could potentially avoid the morbidity of surgery while ensuring that no septic wrist goes untreated.

A randomized trial of diagnostic ultrasound to improve outcomes in focal neuropathies.

INTRODUCTION: Neuromuscular ultrasound is valid, reliable, and accurate, but it is not known whether combining it with electrodiagnostic studies leads to better outcomes in individuals with focal neuropathies. METHODS: One hundred twenty individuals with focal neuropathy, based on history, examination, and electrodiagnosis, were enrolled in this study. All patients underwent neuromuscular ultrasound and were randomized to either have their ultrasound results sent to the referring physician or not have them sent. Outcomes were assessed at 6 months by evaluators blinded to group assignment. RESULTS: The Overall Disability Sum Score and 7 of 8 domains of the Medical Outcomes Study 36-item Short-Form Health Survey (SF-36) showed more improvement in the "report sent" group, although only the general health perception domain was significant (P = 0.005). CONCLUSIONS: Most 6-month outcomes did not reach statistical significance between the 2 groups. However, the "report sent" group had trends toward better outcomes, with significance being reached in the general health perception domain of the SF-36.

Aesthetic outcomes of acellular dermal matrix in tissue expander/implant-based breast reconstruction.

INTRODUCTION: Tissue expander and implant-based breast reconstruction after mastectomy is the most common method of breast reconstruction. Modifications of the traditional total submuscular reconstruction (TSR) have been made using acellular dermal matrix (ADM) to create an inferolateral sling and a more natural implant pocket for superior aesthetic results. The objective of this study was to assess aesthetic outcomes when using ADM in breast reconstruction. METHODS: A retrospective chart review identified all patients who underwent implant-based breast reconstruction from 2005 to 2009 at our institution. Demographic information, complications, reoperations, and aesthetic outcome data were collected for all patients meeting inclusion criteria related to adequate follow-up and postoperative photographs. Five aesthetic outcomes were evaluated for all study patients by 18 blinded evaluators using postoperative photographs. Outcomes were scored on a scale of 1 to 5, with 5 representing the best possible aesthetic score. RESULTS: A total of 122 patients underwent 183 tissue expander-based reconstructions (ADM, n = 58; TSR, n = 125). The infection rate in patients with ADM was 16.2% compared to 5.9% in TSR patients, but this was not statistically significant (P = 0.09). Capsular contracture was more common in TSR patients (23.5%), compared to those with ADM (8.1%), P = 0.048. Aesthetic scores from the attending plastic surgeons were as follows: natural contour (ADM, 3.36; TSR, 3.02; P = 0.0001), symmetry of shape (ADM, 3.57; TSR, 3.27; P = 0.005), symmetry of size (ADM, 3.68; TSR, 3.42; P = 0.002), position on chest wall (ADM, 3.75; TSR, 3.45; P = 0.004), and overall aesthetic appearance (ADM, 3.56; TSR, 3.20; P = 0.0001). CONCLUSIONS: For all 5 aesthetic parameters evaluated, the ADM group scored significantly higher than the TSR group by 18 blinded evaluators. These consistent findings suggest that the use of ADM in breast reconstruction does confer a significant advantage in aesthetic outcomes for breast reconstruction. This is likely at the cost of a higher infection rate when using ADM; however, that may be offset by the advantage of a lower rate of capsular contracture in patients with ADM.

The effect of reusable versus disposable draping material on infection rates in implant-based breast reconstruction: a prospective randomized trial.

BACKGROUND: Clinical infection remains a significant problem in implant-based breast reconstruction and is a physical and emotional strain to the breast reconstruction patient. Bacterial strikethrough of draping and gown material is a likely source of infection. Strategies to reduce infection in implant-based breast reconstruction are essential to improve patient outcomes. OBJECTIVE: The aim of this study is to determine if a disposable draping system is superior to reusable draping materials in the prevention of implant-based breast reconstruction infection. METHODS: This single-institution, prospective, randomized, single-blinded, IRB-approved study enrolled women with breast cancer who were eligible for implant-based breast reconstruction. The primary endpoint was clinical infection by postoperative day 30. Secondary endpoints included all other complications encountered throughout the follow-up period and culture data. Demographic data recorded included patient age, body mass index, diabetes, smoking, chemotherapy, radiation, and follow-up. Procedural data recorded included procedure type, procedure length, estimated blood loss, use of acellular dermal matrix, use of muscle flap, and inpatient versus outpatient setting. RESULTS: From March 2010 through January 2012, 107 women were randomized and 102 completed the study. Five patients were determined not to be candidates for reconstruction after randomization. There were 43 patients in the Reusable Group and 59 patients in the Disposable Group. There were no significant differences in patient demographic data, procedural data, or the type of procedure performed between groups. In the Reusable Group, there were 5 infections (12%) within 30 days compared to 0 (0%) infections in the Disposable Group (P = 0.012). There was no significant difference in secondary complications. There was a trend for positive wound cultures (11% vs. 3%, P = 0.10) and positive drape cultures (17% vs.4%, P = 0.08) in patients with clinical infection. There were no differences in the number of colony-forming units or positive cultures between groups. CONCLUSIONS: Disposable draping material is superior to a reusable draping system in the prevention of clinical infection within the immediate postoperative period. This study did not demonstrate a clear link between intraoperative culture data and the development of clinical infection. A completely disposable gown and draping system is recommended during implant-based breast reconstruction.

Median nerve changes following steroid injection for carpal tunnel syndrome.

INTRODUCTION: Neuromuscular ultrasound is a painless, radiation-free, high-resolution imaging modality for assessment of the peripheral nervous system. The purpose of this study was to use neuromuscular ultrasound to assess the changes that occur in the median nerve after steroid injection for carpal tunnel syndrome (CTS). METHODS: Ultrasound and nerve conduction studies were performed at baseline and 1 week, 1 month, and 6 months after steroid injection in 19 individuals (29 wrists) with CTS. RESULTS: Significant changes were noted in median nerve cross-sectional area (P < 0.001), mobility (P = 0.001), and vascularity (P = 0.042) at the distal wrist crease after steroid injection, and the nerve cross-sectional area correlated with symptom score and electrodiagnostic parameters. Changes in the ultrasonographic parameters were seen within 1 week of injection. CONCLUSIONS: These findings suggest neuromuscular ultrasound is potentially helpful for the assessment of individuals undergoing treatment for CTS, as typical changes can be expected after successful treatment injection.

Dermal Regeneration Template and Staged Skin Grafting for Extirpative Scalp Wound Reconstruction: A 14-Year Experience.

OBJECTIVE: Dermal regeneration template and staged split-thickness skin grafting may mitigate the need for flap coverage of postoncologic scalp defects. This technique has been studied previously in small case series. We examine the effect of risk factors, surgical technique, irradiation, and dressing modalities on reconstructive outcomes in a highly comorbid patient cohort. STUDY DESIGN: Retrospective review. SETTING: Academic medical center. METHODS: Full- and partial-thickness extirpative scalp wounds reconstructed with dermal regeneration template and staged skin grafting were reviewed over a 14-year period. Stage 1 consisted of template application following burr craniectomy in cases lacking periosteum. Stage 2 consisted of skin grafting. Negative pressure wound therapy (NPWT) was variably used to support adherence. RESULTS: In total, 102 patients were analyzed (average age 74, mean follow-up 18 months). Eighty-one percent were American Society of Anesthesiologists class 3 or 4. Defect size averaged 56 cm2. Average skin graft take was 94.5% in full-thickness wounds. Seven patients failed this method. Preoperative scalp irradiation was associated with major complication and delayed graft healing. Comorbidities, wound size, and burring were not associated with complication. Patients were more likely to heal with NPWT compared to bolster (hazard ratio, 1.67; 95% CI 1.01-2.77; P = .046). Time between stages was 6.6 days shorter when NPWT was applied (P < .001). CONCLUSION: Dermal template and staged skin grafting is a reliable option for postcancer scalp reconstruction in poor flap candidates. Radiotherapy is associated with adverse outcomes. Negative pressure wound therapy simplifies postoperative wound care regimens and may accelerate healing.

Impact of sentinel lymph node biopsy on immediate breast reconstruction after mastectomy.

Traditionally, sentinel lymph node biopsy (SLNB) is performed at the time of mastectomy and reconstruction. However, several groups have advocated SLNB as a separate outpatient procedure before mastectomy, when immediate reconstruction is planned, to allow for complete pathologic evaluation. The purpose of this study was to determine the impact of intraoperative analysis of SLNB on the reconstructive plan when performed at the same time as definitive surgery. A retrospective review was conducted of all mastectomy cases performed at a single institution between September 1998 and November 2007. Of the 747 mastectomy cases reviewed, SLNB was conducted in 344 cases, and there was immediate breast reconstruction in 193 of those cases. There were 27 (7.8%) false negative and three (0.9%) false positive intraoperative analysis of SLNB. Touch preparation analysis from the SLNB changed the reconstructive plan in four (2.1%) cases. In our experience, SLNB can be performed at the time of mastectomy with minimal impact on the reconstructive plan. A staged approach incurs significant additional expense, increases the delay in initiation of systemic therapy and the propensity of procedure-related morbidity; therefore, SLNB should not be performed as a separate procedure before definitive surgery with immediate breast reconstruction.

Outpatient reconstruction using integra* and subatmospheric pressure.

Integra (Integra Lifesciences Corporation, Plainsboro, NJ) has been used in a variety of reconstructive surgical procedures. The application of Integra using subatmospheric pressure (V.A.C., Kinetic Concepts, Inc, San Antonio, TX) has been suggested to be easier, faster, and more consistent than previous dressings, allowing grafting as soon as 1 week after Integra placement. Ten patients were chosen for outpatient reconstructive surgery with Integra and subatmospheric pressure with skin grafting 7-10 days (mean = 8 days) post-Integra. Skin graft take was 75% to 100% (mean = 91.5%). No patients required additional grafting or reconstruction. Integra may be successfully used for reconstruction of difficult areas as an outpatient in combination with subatmospheric pressure (V.A.C.). This allows for expedited treatment, decreased morbidity, and lower cost versus standard Integra application.

Use of Integra in the Management of Complex Hand Wounds From Cancer Resection and Nonburn Trauma.

BACKGROUND: Despite extensive use of Integra in burn reconstruction, little has been published regarding its utility in complex hand wounds from nonburn trauma or cancer resection. This study aimed to review outcomes following Integra use for hand reconstruction following cancer resection or nonburn trauma with exposed bone, joints, and/or tendons. METHODS: Retrospective review was performed of patients undergoing hand reconstruction with Integra for exposed bones, joints, or tendons over a 6-year period at a single institution. RESULTS: Fourteen patients underwent hand reconstruction using Integra, 8 following cancer resection and 6 following acute nonburn trauma. The mean defect size was 19 cm2, 79% had exposed tendon without peritenon, 43% had exposed bone without periosteum, and 28% had exposed joint capsule. Mean time from Integra to skin graft was 11.3 days, and negative-pressure wound therapy did not significantly decrease the mean time from Integra to skin graft placement ( P = .76). Overall, 13 patients achieved successful reconstruction with mean skin graft take of 97%, and 1 required revision amputation at the proximal interphalangeal (PIP) joint. Six months postoperative, 92% patients had return of preoperative hand function. Without any surgical revision, 85% of patients were extremely satisfied with the aesthetic result and 15% were fairly satisfied. CONCLUSIONS: Integra is an effective method to treat complex hand wounds with exposed bone, joints, and/or tendons. This technique can be used in the office, lessens the need for local or free flap coverage, and provides an excellent aesthetic outcome. Integra should be considered a viable option in hand reconstruction algorithm.

Vacuum-assisted closure for the treatment of abdominal wounds.

Abdominal wall defects pose a significant surgical challenge. The defect may result from trauma, infections, previous major surgery, or some combination of these etiologies. This article describes the Vacuum-Assisted Closure device (VAC, KCI, San Antonio, Texas) and how it can help in treating these defects.

Acceleration of Integra incorporation in complex tissue defects with subatmospheric pressure.

In an effort to accelerate vascularization and simplify the care of Integra (Ethicon, Inc., Somerville, N.J.), topical subatmospheric pressure was used for eight patients (age range, 2 to 60 years) with complex wounds. Bone was exposed in 62.5 percent of cases, joint in 50 percent, tendon in 37.5 percent, and bowel in 25 percent. The estimated Integra take rate was 96 percent. Split-thickness skin grafting was performed at 4 to 11 days (mean, 7.25 days), with a 93 percent take rate. No adverse side effects were observed with this technique. Application of subatmospheric pressure improved the take rate and time to vascularization of Integra, compared with previous published results, even with complicated wounds. This technique may be a practical alternative to flap closure.

Vacuum-assisted closure for complex cranial wounds involving the loss of dura mater.

The aim in this study was to describe the safety and efficacy of vacuum-assisted closure (VAC) in patients with complex cranial wounds with extensive scalp, bone, and dural defects who were not candidates for immediate free tissue transfer. Five patients (4 men and 1 woman) ages 24-73 years with complex cranial wounds were treated with VAC at Wake Forest Baptist Medical Center. Etiologies included trauma, squamous cell carcinoma, and malignant meningioma. Cutaneous wound defects measured as large as 15 cm in diameter. Four of the 5 patients had open skull defects with concomitant dural defects, and 1 patient had dural dehiscence. After surgical debridement, all 5 patients were treated with the direct application of a VAC device to a reapproximated dura mater (1 patient), to a pericranial flap (1 patient), or to a regenerative tissue matrix overlying CNS tissue (3 patients). In all cases involving open cranial wounds, the VAC device promoted granulation tissue formation over the dural substitute, prevented CSF leakage, and kept the wounds free from local infection. The duration of VAC therapy ranged from 16 to 91 days. Although VAC therapy was intended as a temporary measure until these patients could be stabilized for larger tissue transfer procedures or they succumbed to their primary pathology, 1 patient had a successful skin graft following VAC therapy. Hydrocephalus requiring shunt placement developed in 2 patients during VAC therapy. The VAC dressings applied to a tissue matrix or other barrier over brain tissue in extensive cranial wounds are safe and well tolerated, providing a functional barrier and preventing infection.

Multiple modality treatment regimen in an aggressive resistant fungal hand infection: a case report.

Cutaneous fungal infections are a rare but significant complication associated with immunocompromised states. Lesions allowed to progress to disseminated fungemia are associated with a near 80% mortality rate. Treatment guidelines aimed at local control are vague, centering on wide local excision with systemic antifungal medications. We present the case of a 3-year-old female who, while receiving induction chemotherapy, developed a progressive Aspergillus flavus infection. Involvement included the distal palm and common and proper neurovascular bundles to two fingers. Initial treatments with serial debridement and topical Dakin's solution were unsuccessful in eliminating this fungal infection. A novel treatment using topical voriconazole mixed with Aquaphor® (Beiersdorf AG; Hamburg, Germany) was compounded in the hospital pharmacy to maintain a moist wound healing environment followed by the use of the Vacuum Assisted Closure (VAC®, Kinetic Concepts, San Antonio, TX). Significant improvement was noted within 4 days with this new dressing regimen. Topical voriconazole therapy followed by VAC allowed progressive healing and eventual closure with a split thickness skin graft. The wound was then durably closed, allowing critical chemotherapy to resume. No evidence of systemic fungemia developed, and her clinical recovery preceded laboratory evidence of immune system recovery. Fungal skin infections can be a threat to both life and limb in immunocompromised patients. The armamentarium available to combat this rare but difficult problem is imperfect. In certain infections not responsive to other therapies, the therapeutic regimen described herein should be considered if wide local excision carries significant functional morbidity.

Vacuum-assisted closure for defects of the abdominal wall.

BACKGROUND: Reconstruction of the abdominal wall poses a problem common to many surgical specialties. Abdominal wall defects may be caused by trauma and/or prior surgery, with dehiscence or infection. Several options to repair the structural integrity of the abdominal wall exist, including primary closure, flaps, mesh, and skin grafts. Complications of these procedures include recurrent infection of the abdominal wall, infection of mesh, dehiscence, flap death, and poor skin graft take. Risk factors predisposing to these complications include tissue edema, preoperative tissue infection, and patient debilitation, with poor wound healing potential. Ideally, reconstruction should be performed on a nonedematous, clean tissue bed with bacterial levels less than 10 bacteria/cm in a well-nourished patient. METHODS: Vacuum-assisted closure was used in a series of patients in an attempt to prepare the abdominal wall for reconstruction and reduce the risk of complications. Charts were reviewed for 100 patients who underwent abdominal wall reconstruction after vacuum-assisted closure therapy. Their wound cause, reconstruction technique, complications, and number of days on the vacuum-assisted closure device are reported. RESULTS: The ability of vacuum-assisted closure to reduce edema, increase blood flow, potentially decrease bacterial colonization, and reduce wound size greatly facilitated abdominal wall reconstruction. The vacuum-assisted closure device served as a temporary dressing with which to control dehiscence and to maintain abdominal wall integrity when bowel wall edema prevented abdominal closure. CONCLUSION: Vacuum-assisted closure therapy frequently shortened time to abdominal wall reconstruction and simplified the method of reconstruction.

Vacuum-assisted closure: state of clinic art.

Treatment of wounds has been the cornerstone of plastic surgery since its inception. Vacuum-assisted closure provides a new paradigm that can be used in concert with a wide variety of standard existing plastic surgery techniques. It was originally developed as an alternative treatment for debilitated patients with chronic wounds. It has rapidly evolved into a widely accepted treatment of chronic and acute wounds, contaminated wounds, burns, envenomations, infiltrations, and wound complications from failed operations. The ease of technique and a high rate of success have encouraged its adaptation by thoracic, general, trauma, burn, orthopedic, urologic, as well as plastic surgeons. This article discusses multidisciplinary advances in the use of the vacuum-assisted closure technique over the past 10 years and its status as of 2006. Creative surgeons continue to regularly adapt the system to difficult problems. This technique in trained surgical hands greatly enhances the scope and safety of wound treatment.
