Purpose: Immediate breast reconstruction (IBR) at the time of mastectomy is gaining popularity, as studies show no negative impact on recurrence or patient survival, but better aesthetic outcome, less psychological distress and lower treatment costs. Using the largest database available in Europe, the presented study compared outcomes and complications of IBR vs. delayed breast reconstruction (DBR). Methods: 3926 female patients underwent 4577 free DIEP-flap breast reconstructions after malignancies in 22 different German breast cancer centers. The cases were divided into two groups according to the time of reconstruction: an IBR and a DBR group. Surgical complications were accounted for and the groups were then compared. Results: Overall, the rate of partial-(1.0 versus 1.2 percent of cases; p = 0.706) and total flap loss (2.3 versus 1.9 percent of cases; p = 0.516) showed no significant difference between the groups. The rate of revision surgery was slightly, but significantly lower in the IBR group (7.7 versus 9.8 percent; p = 0.039). Postoperative mobilization was commenced significantly earlier in the IBR group (mobilization on postoperative day 1: 82.1 versus 68.7 percent; p < 0.001), and concordantly the mean length of hospital stay was significantly shorter (7.3 (SD3.7) versus 8.9 (SD13.0) days; p < 0.001). Conclusion: IBR is feasible and cannot be considered a risk factor for complications or flap outcome. Our results support the current trend towards an increasing number of IBR. Especially in times of economic pressure in health care, the importance of a decrease of hospitalization cannot be overemphasized. [ABSTRACT FROM AUTHOR]

Objective: Although in widespread clinical use, evidence of the diagnostic accuracy of radiographic parameters for the diagnosis of scapholunate ligament injuries is scarce. The objective of this study was to evaluate the scapholunate (SL) angle, radiolunate (RL) angle and SL gap as diagnostic parameters for these lesions.Methods: Eight hundred forty nine patients, who underwent wrist arthroscopy at our institution because of wrist pain were included in a retrospective analysis. In all patients the SL angle, RL angle and SL gap were measured on preoperative radiographs. These parameters were correlated with the actual finding of the SL ligament during arthroscopy. Optimal test thresholds were calculated as well as sensitivity, specificity and the likelihood ratios of each parameter.Results: All three parameters proved useful in statistical analysis. The optimal cut-off points for diagnosing lesions of the SL ligament were calculated as 62.5° for the SL angle, 12.5° for the RL angle and 2.5 mm for the SL gap. SL angles had the greatest specificity (0.93).Conclusions: We were able to validate plain radiographs as a reliable tool in the work-up of patients with suspected SL ligament injuries. However, wrist arthroscopy remains the gold standard in diagnosing and treating these lesions. [ABSTRACT FROM AUTHOR]

Introduction: The diagnostic value of clinical tests and magnetic resonance (MR) imaging for the investigation of triangular fibrocartilaginous complex (TFCC) lesions is not clear due to a lack of clinical data. Materials and Methods: We retrospectively analyzed 908 patients who underwent clinical tests and arthroscopy for suspected TFCC lesions at our institution. Further, MR imaging findings concerning the TFCC were gathered. We correlated clinical tests and MR imaging findings with those obtained during arthroscopy, and we calculated sensitivity, specificity, as well as positive and negative predictive values. Results: In the whole cohort, the positive predictive values of all clinical tests were low, ranging from 0.53 to 0.55. The ulna grinding test had the highest sensitivity, but lowest specificity. Sensitivity and specificity of the ulnar fovea sign and magnetic resonance imaging were similar, ranging from 0.73 to 0.76, and from 0.41 to 0.44, respectively. To some degree, the diagnostic value seemed to depend on the Palmer class of TFCC lesion. Conclusions: According to this study, clinical tests and MR imaging findings are of very limited diagnostic value for the diagnosis of TFCC lesions. [ABSTRACT FROM AUTHOR]

Purpose: This study was designed to compare technical parameters during ablation as well as CT 3D rendering and histopathology of the ablation zone between sphere-enhanced microwave ablation (sMWA) and bland microwave ablation (bMWA). Methods: In six sheep-livers, 18 microwave ablations were performed with identical system presets (power output: 80 W, ablation time: 120 s). In three sheep, transarterial embolisation (TAE) was performed immediately before microwave ablation using spheres (diameter: 40 ± 10 μm) (sMWA). In the other three sheep, microwave ablation was performed without spheres embolisation (bMWA). Contrast-enhanced CT, sacrifice, and liver harvest followed immediately after microwave ablation. Study goals included technical parameters during ablation (resulting power output, ablation time), geometry of the ablation zone applying specific CT 3D rendering with a software prototype (short axis of the ablation zone, volume of the largest aligned ablation sphere within the ablation zone), and histopathology (hematoxylin-eosin, Masson Goldner and TUNEL). Results: Resulting power output/ablation times were 78.7 ± 1.0 W/120 ± 0.0 s for bMWA and 78.4 ± 1.0 W/120 ± 0.0 s for sMWA (n.s., respectively). Short axis/volume were 23.7 ± 3.7 mm/7.0 ± 2.4 cm for bMWA and 29.1 ± 3.4 mm/11.5 ± 3.9 cm for sMWA ( P < 0.01, respectively). Histopathology confirmed the signs of coagulation necrosis as well as early and irreversible cell death for bMWA and sMWA. For sMWA, spheres were detected within, at the rim, and outside of the ablation zone without conspicuous features. Conclusions: Specific CT 3D rendering identifies a larger ablation zone for sMWA compared with bMWA. The histopathological signs and the detectable amount of cell death are comparable for both groups. When comparing sMWA with bMWA, TAE has no effect on the technical parameters during ablation.

Background: This retrospective study was performed to verify the advantages and disadvantages of the free lateral arm flap for defect reconstruction of the forearm and hand. Patients and Methods: Between 2001 and 2010, 21 patients underwent defect coverage of the forearm and hand with the free lateral arm flap. The mean patient age was 48 years (17-78). The results concerning defect origin, flap size, pedicle length, operative time, revisions of the anastomoses or other complications, donor site morbidity, and length of hospital stay were evaluated. Results: The majority of defects were caused by infections or chronic wounds. The defects were localized at the forearm in 6 cases and at the hand in 15 cases. The flap width ranged from 3 to 8 cm, and the length was from 5 to 20 cm. All flaps survived. Only in one case, a revision of the anastomosis was necessary. Primary closure of the donor site was possible in all patients. No complications occurred during the healing procedure. The majority of the patients were satisfied with the aesthetic result at the recipient site as well as at the donor site. Conclusion: The free lateral arm flap is a very reliable option for defect coverage at the forearm and hand for small and medium size defects. A satisfactory aesthetic appearance, an excellent tissue quality, and frequent primary donor site closure are great advantages for selecting this flap. [ABSTRACT FROM AUTHOR]

Today an increasing number of patients seek aesthetic improvement through minimally invasive procedures, and interest in soft tissue augmentation and filling agents is rising steadily. However, a thorough understanding of these substances, their indications and contraindications, as well as a profound knowledge of different implantation techniques is essential to provide an aesthetically pleasing result for the patient. This presentation gives an overview of the current injectable biomaterials, their major indications, advantages and disadvantages, with focus on collagen, hyaluronic acid, poly- l-lactide, and autologous fat grafting.

Background: The majority of patients with trapeziometacarpal joint (TMJ) arthritis can be successfully treated with some form of arthroplasty. Residual pain therefore is rather uncommon, but particularly difficult to treat. The aims of this study were to determine the number of patients in need of additional surgery; to identify the most common causes for persistent pain and to establish a treatment algorithm. Patients: Twelve patients (11 females, 1 male) who had undergone secondary surgery after TMJ arthroplasty were retrospectively analyzed at a mean time of 32 months after the primary procedure. Parameters included the indication for secondary surgery, the type of procedure, the ultimate range of motion, residual pain levels, upper extremity function assessed by the DASH score and the distance from the first metacarpal bone to the scaphoid. Results: The overall results were assessed according to the Conolly score. The revision rate after primary arthroplasty at our institution was 2.9%. Most common problems for secondary surgery included mechanical pain due to crepitation of the base of the first metacarpal bone, neuropathy of the superficial branch of the radial nerve and concomitant scaphotrapezial arthritis. A total of 19 procedures were performed resulting in two good, five fair and five poor results. A treatment algorithm is presented. [ABSTRACT FROM AUTHOR]

This article presents a retrospective analysis of a series of nine patients requiring reconstruction of exposed bone, tendons or joint capsules as a result of acute high-voltage injuries in a single burn centre. As an alternative to free tissue transfer, the dermal substitute Matriderm((R)) was used in a one-stage procedure in combination with split-thickness skin grafts (STSG) for reconstruction. Nine patients, in the period between 2005 and 2009 with extensive high-voltage injuries to one or more extremities which required coverage of exposed functional structures as bone, tendons or joint capsule, were included. A total of 11 skin graftings and 2 local flaps were performed. Data including regrafting rate, complications, hospital stays, length of rehabilitation and time until return to work were collected. Eleven STSG in combination with Matriderm((R)) were performed on nine patients (success rate 89%). One patient died. One patient needed a free-flap coverage as a secondary procedure. The median follow-up was 30 months (range 6-48 months). The clinical results of these nine treated patients concerning skin-quality and coverage of exposed tendons or joint capsule were very good. In high-voltage injuries free-flap failure occurs between 10% and 30% if performed within the first 4-6 weeks after trauma. The use of single-stage Matriderm((R)) and skin grafting for immediate coverage described in this article is a reliable alternative to selected cases within this period. [ABSTRACT FROM AUTHOR]

During 30 months, 40 “septum-based” mammaplasties with a craniomedial pedicle were performed. This report aims to demonstrate the anatomic basics of the horizontal septum and the authors’ experience with the septum-based mammaplasty technique. A series of 40 consecutive patients underwent a “septum-based” mammaplasty. This technique uses a medial pedicle based on Würinger`s horizontal septum, which is the main plain for the neural and vascular supply of the nipple–areolar complex (NAC). The mean nipple-to-sternal-notch distance was 32 cm (range, 24–43 cm). The mean resection weight was 648 g (range, 484–1,320 g), and the mean nipple elevation was 9.5 cm (range, 5–18 cm). There were no hematomas and no partial or complete NAC necroses. Minimal wound dehiscence at the T-junction was present in three cases (7.5%). The pre- and postoperative NAC sensibilities were comparable in all the patients. Based on Würinger`s horizontal septum, a safe and well-vascularized mammaplasty is possible even with large resection weights and long nipple–areola distances, and NAC sensibility can be preserved. The reported technique combining excellent pedicle perfusion with a wide variety of breast shaping proved to be safe. [ABSTRACT FROM AUTHOR]

In situations of bony nonunions with poor skin coverage, transplantation of vascularized soft tissue in addition to bone graft is desirable. The use of the corticoperiosteal vascularized bone graft from the medial femoral condyle is well described. There are only anecdotal reports about its use as an osteocutaneous flap. This article presents our results with the use of an osteocutaneous flap from the medial femoral condyle. Between 2004 and 2009, four patients were treated with supracondylar osteocutaneous flaps for bony nonunions (tibia, ankle, calcaneous) with concomitant soft tissue defects. The size of the osseous grafts ranged from 3 � 5 to 6 � 5 cm. The supplying cutaneous vessels were an unnamed perforator of the descending genicular artery (two cases) or the saphenous branch (two cases). The first three cases healed primarily. Bony union was achieved between 32 and 170 days. The follow-up of the fourth case was too short to achieve a bony union. There was no flap loss or surgery-related complications at the donor site. The transfer of free combined vascularized corticoperiosteal-cutaneous flaps seems to be ideally suited for postradiation-induced fractures or chronic nonunions with poor chances of spontaneous healing and a concomitant small skin defect.

This study evaluated the effectiveness of a patient-oriented, hand rehabilitation programme compared to a standard programme regarding functional outcomes, return to work, patient satisfaction and costs. Patients were recruited in two consecutive cohorts. One cohort received the standard treatment programme (n = 75) and the other a programme based on principles of patient orientation (n = 75). Data were collected at the beginning and end of rehabilitation and 6 months after discharge. Clinical variables included range of motion, grip and pinch strength. Self-reported measures included pain, upper extremity functioning, health status, satisfaction and job situation. Analysis of variance for repeated measurements was used to calculate the main effects. The patient-oriented group showed more favourable results with respect to DASH scores (P <.05), pain (P <.001) and patient satisfaction (P <.0001). More patients returned to their former jobs and time off sick was reduced. We concluded that the patient-oriented approach was more effective and cost-saving. [ABSTRACT FROM PUBLISHER]

Gynecomastia is a potential side effect of hormone therapy for prostate cancer. In large, randomized, placebo controlled studies approximately 50% or more of patients with prostate cancer experienced gynecomastia attributable to various mechanisms. Although it is mostly reported as mild to moderate, gynecomastia is one of the reasons most frequently cited for premature discontinuation of such treatment. Prophylactic radiotherapy and prophylactic tamoxifen have been shown to decrease the incidence of hormone-induced gynecomastia; nevertheless, there are still cases of refractory gynecomastia, and in these plastic surgery is needed for correction. Gynecomastia is a benign enlargement of the male breast, requiring no treatment unless it is a source of embarrassment and/or distress for the adolescent or man affected. The indications for surgical treatment of gynecomastia are founded on two main objectives: restoration of the male chest shape and diagnostic evaluation of suspected breast lesions. The authors believe that the complete circumareolar technique with no further scarring creates the best aesthetic results with fewer complications. When this is used in combination with liposuction very pleasing aesthetic results can be achieved. [ABSTRACT FROM AUTHOR]

Necrotizing soft-tissue infections such as necrotizing fasciitis continue to have a high morbidity and mortality. More and more, these difficult cases are being referred to burn centers for specialized wound and critical care treatment. The case of a necrotizing soft-tissue infection after a honeybee sting is reported. To the best of our knowledge, it is the first documented case of necrotizing fasciitis caused by invasive group A Streptococcus from a bee sting. A 56-year-old man was stung by a bee in the left upper gluteal region. The sting was removed by the patient. Within hours, erythema, swelling, itching, and pain developed. On day 7, after the bee sting, the patient was admitted to a general surgery department with progressive skin and soft-tissue necrosis around the hip and the upper left leg. Because of the rapidly deteriorating condition, the patient was referred to our burn ICU with the picture of a progressive necrotizing fasciitis. The skin necrosis required immediate epifascial necrectomy. Additionally local therapy with topical antiseptics was performed. The surface was temporarily covered with xenograft, definitive coverage was achieved with autologuous skin graft transplantation. Advancements in wound care and critical care, which have become standard in the treatment protocols of patients with necrotizing soft-tissue infections, have markedly improved the prognosis. However, these infections continue to be a source of high morbidity and mortality and significant healthcare resource consumption. These challenging patients are best served with prompt diagnosis, immediate radical surgical debridement, and aggressive critical care management. Referral to a burn center may help to provide best possible surgical intervention, wound care, and critical care management. [ABSTRACT FROM AUTHOR]
