Upper Extremity Infections in the Transplant Population.

PURPOSE: As the duration of lifetime survival after organ transplantation continues to increase, the consequences of long-term immunosuppression, such as opportunistic and rare infections, are a high-risk reality. This study examined upper extremity infections in the transplant population to determine the current clinical risk profile, management, and outcomes. METHODS: An institutional database of 16,640 patients who underwent transplantation was queried for upper extremity infections from 2005 to 2017, defined as the presence of infection from the shoulder to the fingertips. The resulting data were analyzed using multivariable linear and logistic regression modeling. RESULTS: A total of 230 eligible patients experienced upper extremity infections at a mean age of 54.1 ± 15.3 years, occurring, on average, 7.9 ± 8.6 years after transplantation. The most commonly transplanted organ was the kidney (51.3%), followed by the liver (20%). The most common location of infection was the forearm (31.7%), digits (27.4%), and upper arm (17%). The most common types of infection were cellulitis (69.1%), abscess (33.5%), joint sepsis (6.5%), infectious tenosynovitis (3.9%), and osteomyelitis (1.3%). Patients taking an antifungal medication, those who had a joint infection, or those who had undergone lung transplantation had an approximately 2.5-day longer stay in the hospital. For every 1-year increase in age at the time of transplantation, the time from transplantation to infection decreased by 0.21 years. Those who had undergone bone marrow transplantation or those who were taking tacrolimus were expected to have approximately 8- and 6-year decreases, respectively, in the time from transplantation to infection. CONCLUSIONS: Upper extremity infections should be individually evaluated and treated because of the heterogeneity of transplant type, immunosuppression medications, the age of the patient, and infection characteristics.

Free vascularized fascia lata flap for total columella reconstruction.

INTRODUCTION: Despite their relatively small size, columellar defects, including both external and internal elements, are exceedingly difficult to reconstruct. Local, regional, and distant flaps have been described for reconstruction. Herein, we present a novel technique for reconstruction of the columella using vascularized free fascia lata from the anterolateral thigh with structural replacement and skin grafting. METHODS: This novel technique utilizes a small anterolateral thigh flap, formed into vascularized fascia lata without the overlying subcutaneous fat or skin. The fascia lata is inset into the columellar and caudal septal defect after a cartilage framework is constructed and is microsurgically anastomosed to either distal facial or angular vessels. A skin graft from the ALT donor site is then secured over the fascia. RESULTS: This technique has been applied successfully in patients with either isolated columella or in multi-subunit reconstruction following total rhinectomy with no flap or reconstructive failures. Given the low morbidity of flap harvest and minimal access incisions, this has been reliably accomplished with short (1-2 day) hospital stays. CONCLUSION: Rapid and aesthetically acceptable reconstruction of total nasal columella defects in isolation or with additional nasal subunit reconstruction, is possible utilizing this novel technique. Here we discuss pearls and pitfalls of its use following surgical resection of malignancy.

Ten-Year Institutional Experience to Predict Risk of Calvarial Bone Flap Loss Using Long-Term Outcome Data.

BACKGROUND: Calvarial bone flap (CBF) loss is a common complication following craniotomy and subsequent skull reconstruction can be challenging. Defining predictors of CBF failure not only improves patient outcomes but reduces the need for complex reconstruction often requiring plastic surgery consultation. As CBF failure can occur many years following craniotomy, this study aimed to determine risk factors of CBF loss using long-term follow-up. MATERIALS AND METHODS: This retrospective study included patients who underwent craniotomy with CBF reinsertion between 2003 and 2013 at a tertiary academic institution. Patients were included if demographics, comorbidities, and long-term outcomes were available. Multivariable logistic regression modeled the odds of CBF failure, defined as permanent removal for bone flap-related issues. The median follow-up was 6.9 years (interquartile range: 1.8-10.8 y). RESULTS: There were 222 patients who met inclusion criteria and underwent craniotomy with CBF reinsertion, primarily for tumor resection or intracranial pressure relief. CBF failure occurred in 76 (34.2%) patients. Up to 4 CBF reinsertions were performed in both failure and nonfailure groups. The risks of CBF loss increased with each additional CBF elevation by 17-fold ( P <0.001), male sex by 3-fold ( P =0.005), and tumor etiology by 3-fold ( P =0.033) ( C -index=0.942). CONCLUSIONS: Each CBF reinsertion dramatically increases the risk of CBF loss. This finding may optimize patient selection and surgical planning. Early multidisciplinary discussions between plastic surgeons and neurosurgeons may avoid multiple CBF elevations and prevent the adverse sequela of high-risk calvarial reconstruction efforts.

Traumatic Facial Myopericytoma: A Differential to Consider.

Myopericytoma is a slow-growing, benign soft tissue neoplasm that arises from perivascular smooth muscle cells. This tumor is a rare entity itself, but it is only scarcely mentioned in the literature occurring secondary to trauma. The authors report a 21-year-old male patient who presented with a pulsatile mass in the medial canthal area where he had experienced previous trauma from a car accident 1-year prior. The mass was excised and histopathology revealed myopericytoma. This clinical report adds to the limited body of evidence supporting trauma as an etiology for this rare tumor.

A controlled cost and outcomes analysis of acellular dermal matrix and implant-based reconstruction.

INTRODUCTION: The use of acellular dermal matrix (ADM) for breast reconstruction continues to change in both single- and two-stage reconstruction. Determining optimal outcomes clinically, aesthetically, financially as well as for the patient's quality of life has become a priority. METHODS: A retrospective review of implant-based reconstructions was performed at a single center from 2010 to 2016, with patients blindly matched 1:1:1 into three cohorts based on reconstruction type: 1) single stage direct to implant with ADM, 2) two-stage tissue expander to implant (TE/I) without ADM, and 3) two-stage TE/I with ADM. Relative cost between groups, esthetic outcomes, and quality of life within each group was analyzed. RESULTS: Group 1 was more likely to be older and use intraoperative angiography, but with fewer overall surgeries and postoperative visits (p<0.001). There was no statistically significant difference in reconstructive success among all three groups (p = 0.85). Cost was significantly higher for group 3 relative to groups 1 and 2. Overall appearance was higher in groups 1 and 3 relative to group 2, with radiation therapy the only independent factor. Group 1 had higher scores using Breast-Q for the physical well-being domain (p = 0.01). CONCLUSION: This is the first study to incorporate clinical outcomes, esthetic visual grading, and patient-reported quality within the same cohort of individuals, considering both use of ADM and staging. Despite the added ADM cost, it is proven safe, eliminates time and cost associated with tissue expanders, decreases post-operative visits and can lead to equally as functional and aesthetically pleasing outcomes in single- and two-stage breast reconstructions.

Pushing the Envelope: Skin-Only Mastopexy in Single-Stage Nipple-Sparing Mastectomy with Direct-to-Implant Breast Reconstruction.

BACKGROUND: Despite advances in skin envelope reduction techniques and experienced nipple-sparing mastectomy flap procedures, the rate of nipple malposition and secondary revision in these patients remains high and eligible candidates are limited. In this article, the authors present a novel technique combining skin reduction nipple-sparing mastectomy surgery with single-stage skin-only mastopexy and direct-to-implant reconstruction. METHODS: A retrospective review was performed at a single institution from 2015 to 2018. All patients were operated on using this technique consecutively, by a breast and plastic surgeon team (A.F. and A.M.). Surgical technique and outcomes were compared with the currently accepted literature. RESULTS: Twenty-six patients (40 breasts) underwent this technique; all were single-stage direct-to-implant reconstructions. The average body mass index was 31 kg/m2. A Wise pattern was used in 35 breasts (87.5 percent) and prepectoral placement was used in 25 breasts (62.5 percent). Overall complications included seroma [n = 6 (15 percent)], vertical/T-junction dehiscence [n = 4 (10 percent)], skin necrosis [n = 4 (10 percent)], superficial or partial nipple necrosis [n = 4 (10 percent)], with no total nipple-areola complex lost and no reconstructive failures at 18.7 months' average follow-up. CONCLUSIONS: In this article, the authors share a novel reconstructive technique in which the skin envelope is reduced, the nipple-areola complex is repositioned, and a direct-to-implant reconstruction is performed in a single stage at the time of mastectomy. Consideration of pearls and pitfalls accompanies a review of the authors' experienced complication profile, and is discussed in the context of current literature. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Small Finger to Ring Finger Ray Transposition: Modern Surgical Technique and Case-based Review of the Literature.

Ray transposition for central digital amputation has been performed following traumatic injury to the hand for decades. Small finger to ring finger ray transposition has been well described in the literature, with good functional and aesthetic outcomes reported. Originally described by Bunnell, the fourth metacarpal can be disarticulated and the fifth metacarpal base transposed with reconstruction of the intermetacarpal ligament allowing progressive closure between the third and fifth rays. However, osteotomy-based transpositions are utilized placing the osteotomy at the level of the metacarpal, followed by transposition and fixation of the small finger to the base of the ring finger metacarpal; or, by making an intracarpal wedge-osteotomy of the hamate with subsequent radial translocation of the entire small finger ray. Recent literature has suggested the intracarpal wedge osteotomy to be superior technically, and with less postoperative complications. However, for this somewhat uncommon reconstructive procedure, no high-level evidence exists to determine which of these techniques is truly more favorable. Here, we present an interesting case of ray amputation and transposition following an isolated fourth metacarpal traumatic firearm injury, and comprehensive modern surgical technique. Upon review of the literature, small to ring finger ray transposition has been shown to have acceptable functional and aesthetic outcomes regardless of the osteotomy technique used, and should be considered when the nature of presenting injury and the patient's lifestyle and postoperative expectations are appropriate.

Assessment of long-term kyphosis following transthoracic corpectomy with single adjacent level posterior instrumentation.

Anterior thoracic spinal instrumentation has traditionally been supported by a posterior thoracic construct spanning from at least two levels above to two levels below; however, instrumentation at a single-level above and below may be adequate to support such a construct. We report two cases of transthoracic corpectomy with short-segment posterior fixation with success in long-term stabilization. Two patients with thoracic vertebral malignancy resulting in spinal deformity and spinal cord compression underwent transthoracic corpectomy with placement of an expandable cage proceeded by posterior fixation one level above and one level below. Using the Cobb angle, the degree of kyphosis was measured at 3, 6, and 12 months postoperatively. Long-term spinal stabilization was achieved in both patients. There was no significant increase in kyphosis and no evidence of hardware failure in either patient during the follow-up period. Transthoracic corpectomy with supplementary posterior fixation one level above and below may be adequate to stabilize the spine.
