Background: Inadequate wound closure is a feared complication following total knee arthroplasty (TKA). A knee with a multiple operative history, excessive scarring, and fibrosed surrounding soft tissue presents a significant challenge. In cases with preoperative uncertainty for sufficient soft tissue coverage because of ischemia and tension on closure, soft tissue expansion (STE) has been reported to be an effective tool for optimizing successful closure.

Case report: For the case in this report, STE was performed on a knee with multiple scars, potential ischemia, fibrosis, and soft tissue contractures prior to TKA.

Conclusions: In cases of uncertain soft tissue coverage in TKA, the use of STE can be a useful method in creating adequate wound closure.

Background. Extensive degloving skin injuries in children are particularly challenging for the possible complications of restricting growth and function. Biodegradable temporizing matrix (BTM, PolyNovo) is traditionally used for acute burn care reconstruction and in this case was successfully used to manage a child with lower limb open fractures associated with severe degloving injuries. This novel use offers excellent short and intermediate outcomes.

Background: Breast reconstruction in the obese patient is often fraught with poor patient satisfaction due to inadequate volume restoration. The off-label hyperinflation of saline implants is a direct yet controversial solution to this problem, with limited studies in the literature. This study sought to determine the safety and efficacy of this technique for breast reconstruction.

Methods: A retrospective chart review was performed to identify all patients with a body mass index (BMI) greater than or equal to 30 kg/m2 who underwent breast reconstruction between the years 2013 to 2020 with saline implants filled beyond the manufacturer's maximum recommended volume.

Results: The 21 patients identified had an average age of 49 years. The mean BMI was 39.5 kg/m2. A total of 42 implants were placed; 34 were 800 mL, 4 were 750 mL, and 4 were 700 mL. The average overfill volume was 302 mL (138%). Mean follow-up was 65.0 months. Of these, 1 (4.8%) patient with a history of chest wall radiotherapy underwent reoperation for unilateral implant exposure 27 days after the index procedure, no patient sustained spontaneous leak or rupture, and 1 patient had unilateral deflation following emergent central line and pacemaker placement 2 years after the implant was placed for an unrelated cardiovascular event.

Conclusions: Hyperinflation of saline implants beyond the maximum recommended volume may be considered for volume replacement in obese patients undergoing implant-based breast reconstruction. This practice is well tolerated, has a complication rate comparable to using implants filled to the recommended volume, and has the potential to restore lost breast volume in the obese patient post mastectomy.

Background: Fournier gangrene (FG) is a necrotizing fasciitis involving perianal and abdominal regions. It progresses quickly and requires urgent intervention. With the use of vacuum-assisted closure (VAC) treatment applied during clinical follow-up and the use of superomedial thigh flap in the region, the treatment is completed with an effective, functional, and rapid approach. This study examines the clinical details of this method for reconstruction.

Methods: The study included 15 patients who underwent superomedial thigh flap in VAC treatment reconstruction for tissue defect after FG debridement from 2016 to 2020. The patients were examined in the form of clinical evaluation with hospital admission and surgical evaluation in the postop process.

Results: In patients with wound maturation and sufficient granulation, superomedial thigh flap application followed by VAC treatment soon after shortened the operation time, shortened the postop drain time, and provided effective treatment of dead space. An aesthetic and functional result was obtained with the proximity of the flap to the area. In addition, due to the sensory branches present in the flap, a sensory result was obtained according to the ratio of flap size.

Conclusions: Superomedial thigh flap provides a practical, effective, and fast solution to the tissue defect that occurs after FG debridement. Effective results can be obtained when combined with VAC therapy.

Background: Despite increasing disease prevalence, there remains a paucity of data examining surgical treatments for gouty tophi. This article assesses en masse excision and curettage of articular tophi involving the hands and shows that carefully planned and precisely executed surgery can consistently alleviate pain, preserve function, and enhance the aesthetics of afflicted hands.

Methods: A retrospective review was conducted of all consecutive patients who underwent surgical excision of tophaceous deposits from the upper extremity. All patients had an established diagnosis of gout and had been treated with urate-lowering medication. All tophi were substantive in size and were causing significant digital joint dysfunction and disfigurement with variable skin ulcerations.

Results: The study group included 12 patients with 24 tophaceous deposits excised from the metacarpal and interphalangeal joints; 2 deposits were also concomitantly excised from the wrist and 2 from the elbow. The study group included 8 men and 4 women, with an average age of 67 years. Follow-up evaluation ranged from 2 to 15 years. All patients underwent successful tophus excision with restoration of tendon excursion and joint mobility without wound complications. All regained high levels of function, and all reported satisfaction with their outcome. On follow-up for as long as 15 years, recurrence has not been observed and secondary surgery has not proved necessary.

Conclusions: This study indicates that surgical excision of articular tophi of the hands can provide long-term improvement in function and aesthetics with minimal risk of wound complications or recurrence.

Background: Electrical stimulation (ES) therapy is recommended for healing pressure injuries. Monophasic pulsed microcurrent stimulation promotes the migration of human dermal fibroblasts (HDFs) to the cathode, and ES potentially accelerates pressure injury healing. A reverse current is generated after ES in the human body; however, the effects of the electrical shunt in preventing the reverse current from migrating are unclear. Therefore, this study aimed to investigate the effects of an electrical shunt on the migration of HDFs.

Methods: In the shunt groups, HDFs were electrically stimulated (0, 200, 400, and 600 µA) for 8 hours, and an electrical shunt was used to remove the electricity after ES. HDFs were observed under time-lapse microscopy for 24 hours. The migration ratio toward the cathode was calculated for each dish.

Results: The migration ratio was significantly higher in the 200-µA group than in the other groups. HDFs migrated toward the anode after ES in the non-shunt groups with greater than 400 µA ES; however, HDFs did not migrate toward the anode with electrical shunting.

Conclusions: A post-ES electrical shunt is important in preventing a decline in the migration effect of ES.

Background. Surgical procedures for squamous cell carcinoma of the penis generally involve primary closure, partial glansectomy, skin graft, and penile amputation. Partial penile resection can result in not only unsightly deformation of the penis but also functional disorders of the urinary line as well as psychological effects due to subjective perceptions of a loss of power and masculinity. With the use of an organ-preserving procedure for functional reconstruction without compromising oncological control, this report describes a new procedure for performing functional penile reconstruction with an auricular cartilage composite graft.

Background: Contrast media extravasation injuries are uncommon, and both conservative and surgical management approaches have been previously described. Over time the use of lower osmolar contrast solutions has prompted fewer complications, whereas the use of automated infusion systems has increased the overall incidence. Local radiology departments frequently have their own protocols for the initial management of extravasation injuries, but if the injury is considered more severe or results in soft tissue compromise, the plastic surgery department is often consulted. Surgical management options depend on the nature of the agent and the degree of extravasation. Stab incisions of the overlying skin followed by the application of pressure have been described for injuries which are more severe.

Methods: Two cases were compared in the context of the prevailing literature. One of these was a large volume extravasation of an iodine-based imaging contrast agent with a diffuse distribution pattern, rendering it unsuitable for this method of evacuation. This is contrasted with a case with a more discrete collection better suited to acute evacuation.

Results: This review found that current literature does not account for distribution patterns of extravasation medium in the decision-making process around surgical intervention.

Conclusions: A review of the relevant literature suggests that the pattern of distribution should be accounted for when considering surgical management.
