Objective Porcine-derived xenograft biological dressings (PXBDs) are occasionally used to prepare chronic wound beds for definitive closure before split-thickness skin grafts (STSGs). We sought to determine whether PXBD influences rate of STSG take in lower-extremity wounds. Methods Lower-extremity wounds treated with STSGs were retrospectively reviewed. Patients were included in one of two groups: wound bed preparation with PXBD before STSG or no preparation. Patients were excluded if they received wound bed preparation via another method. Patient demographics, comorbidities, wound history, wound bed preparation, and 30- and 60-day outcomes were collected. Results There was no difference in healing outcomes between the PXBD (n = 27) and no preparation (n = 39) groups. At 30- and 60-day follow-up, percentage of STSG take was not significantly different between groups (77.9% versus 79.0%, P30 = .818; 82.2% versus 80.9%, P60 = .422). Mean wound sizes at these follow-up periods were not different (4.4 cm2 versus 5.1 cm2, P30 = .902; 1.2 cm2 versus 1.1 cm2, P60 = .689). The PXBD group had a higher mean ± SD hemoglobin A1c level (8.3 ± 3.5 versus 6.9 ± 1.6; P = .074) and age (64.9 ± 12.8 years versus 56.3 ± 11.9 years; P = .007) versus the no preparation group. Conclusions Application of PXBDs for wound bed preparation had no effect on wound healing compared with no wound bed preparation. The two groups varied only by mean age and hemoglobin A1c level. The PXBD may be beneficial, but these results call for randomized controlled trials to determine the true impact of PXBDs on wound healing. In addition, PXBDs may have utility outside of clinically oriented outcomes, and future work should address patient-reported outcomes and pain scores with this adjunct.

We report our experience with the use of Integra® for the management of severe traumatic wounds of the hand. Fifteen patients were treated with follow-up ranging from 10 to 37 months. Wounds were associated with an osseous and/or joint and/or tendon exposure. Following Integra® placement, patients were managed with dressings and subsequent split-thickness skin grafting an average of 26 days later. Integra® was successful in achieving durable, functional and aesthetic definitive coverage in 13 of 15 applications while allowing a satisfying pollicidigital prehension. Regarding our clinical experience, Integra® is an effective technique to deal with severe wounds of the hand with exposed tendon and/or bone and/or joint, even in the absence of paratenon or periosteum. This can potentially lessen the need for local rotational or free flap coverage and should be taken into consideration as a viable alternative in traumatic reconstruction of the hand.

Abstract Patients who suffer hand burns are at a high contracture risk, partly due to numerous cutaneous functional units, or contracture risk areas, located within the hand. Patients who undergo split-thickness skin grafting are often immobilized postoperatively for graft protection. Recent practice at our burn center includes an early range of motion (EROM) following hand grafting to limit unnecessary immobilization. The purpose of this study was to determine whether EROM is safe to perform after hand grafting and if there is any clinical benefit. This retrospective, matched case–control study of adults compared patients who received EROM to subjects who received the standard 3 to 5 days of postoperative immobilization. Patients were evaluated for graft loss and range of motion. Seventy-one patients were included in this study: 37 EROM patients and 34 matched controls. Six patients experienced minor graft loss, three of these were not attributable to EROM. All graft loss was less than 1 cm and none required additional surgery. Significantly more patients who received EROM achieved full-digital flexion by the first outpatient visit (25/27 = 92.6% vs 15/22 = 68.2%; P = .028). Performing EROM does not cause an increase in graft loss. All areas of graft loss from the EROM group healed without intervention. There appears to be a benefit to EROM since there was a significant improvement in the patients’ ability to make a full fist at initial outpatient follow-up. Additional prospective analysis is needed to examine the true clinical utility of EROM in the hand and other contracture-prone areas.

Abstract Scars are the final result of the four processes that constitute cutaneous wound healing, namely, coagulation, inflammation, proliferation, and remodeling. Permanent scars are produced if the wounds reach the reticular dermis. The nature of these scars depends on the four wound healing processes. If the remodeling process is excessive, collagen degradation exceeds collagen synthesis and atrophic scars are produced. If the inflammation phase is prolonged and/or more potent for some reason, inflammatory/pathological scars such as keloids or hypertrophic scars can arise. If these pathological scars are located on joints or mobile regions, scar contractures can develop. When used with the appropriate timing and when selected on the basis of individual factors, surgical techniques can improve mature scars. This review paper focuses on the surgical techniques that are used to improve mature scars, burn scars, and scar contractures. Those methods include z-plasties, w-plasties, split-thickness skin grafting, full-thickness skin grafting, local flaps (including the square flap method and the propeller flap), and expanded flaps, distant flaps, regional flaps, and free flaps.

ABSTRACTLymphoedema is a progressive condition that can have a marked physical and psychological impact on affected patients and significantly reduce the quality of life. The ulcers on chronic lymphoedema patient, which often also makes it impossible for them to work. If left untreated, tends to progress or worsen. Ulcers in lymphoedema patients, therefore, represent not only a medical but also a psychological problem. The treatment is often regarded as being worse than it actually is. In our study of more than 25 years shows around 10% cases are due to chronic lymphodema. Ulcers of chronic lymphoedema are classified into four stages according to their presentation. Their management depends upon their stage of presentation. Patients with chronic lymphoedema and ulceration require a different approach to treatment. The specific issues associated with managing the patient with lymphoedematous ulceration include, limb shape distortion i.e., elephantiasis, care of the skin creases and folds, and swelling of the toes and fore foot. Stage I ulcers will heal with conservative treatment without any surgical intervention. Stage II ulcers needs debridement of the wound and split-thickness skin grafting. The most difficult to treat are the stage III and IV ulcers, due to associated skin changes and reduced vascularity. These cases need debulking along with excision of the ulcer. In order to prevent recurrence of the ulcer in all the four stages needs prolonged follow-up and limb care.

Abstract Introduction Patients who suffer hand burns are at a high risk for developing contractures, partly due to the presence of numerous cutaneous functional units, or contracture risk areas, located within the hand. Patients who undergo split-thickness skin grafting (STSG) are often immobilized post-operatively for graft protection. Restricting mobility following a STSG is thought to protect against subdermal edema and shear forces, despite limited evidence. Early range of motion (EROM) has been described previously. Recent practice at our burn center includes EROM following hand STSG to limit unnecessary immobilization. The purpose of this retrospective study was to determine if EROM is safe to perform after hand STSG and if there is any clinical benefit. Methods In an approved, retrospective, matched case-control study of adult patients who sustained hand burns, patients who received EROM were defined as cases; patients who did not receive EROM were considered controls and received the standard 3–5 days of post-operative immobilization in a resting hand splint. Adult patients admitted over a 3-year period were eligible for inclusion. Patients were evaluated for graft loss and range of motion. Results Seventy-two patients were included in this study; 37 EROM patients and 35 matched controls. EROM patients tended to have a larger area excised (170.4 ± 69.8cm2 vs. 132.9 ± 76.2cm2; p=0.034) and grafted (171 ± 70.8 cm2 vs. 132.9 ± 76.2 cm2; p=0.033). Most patients were male, with an average age of 39 years. Patients had an average of approximately 5% TBSA burns with 1.5% to the hands. On post-op day (POD) 1 and 2, patients received EROM for an average of 30 minutes (29.25 ± 14.9 vs. 31 ± 16.4 minutes). Six patients experienced minor graft loss. Three patients (8%) experienced graft loss not attributable to EROM. One patient (2.7%) experienced graft loss pre-EROM on POD2 and 3 patients (8%) experienced graft loss post-EROM on either POD1 or POD2. All graft loss was less than 1 cm in greatest dimension and no patient who experienced graft loss required additional surgery as they all closed by their first outpatient follow-up. Significantly more patients who received EROM achieved full digital flexion by the first outpatient visit (25/27=92.6% vs. 15/22=68.2%; p=0.028). Conclusions Performing EROM does not cause an increase in graft loss. All areas of graft loss from the EROM group healed without intervention. There appears to be a benefit to EROM since there was a significant improvement in the patients’ ability to make a full fist at initial outpatient follow up. Further prospective analysis is needed to examine the true clinical utility of EROM in the hand and other contracture-prone areas. Applicability of Research to Practice Clinical change in post-operative management after hand grafting.

Abstract Background Split-thickness skin grafting is the current gold standard for the treatment of traumatic skin loss. However, for patients with extensive burns, split-thickness skin grafting is limited by donor skin availability. Grafting split-thickness skin minced into micrografts increases the expansion ratio but may reduce wound repair quality. Dermal substitutes such as Pelnac can enhance the healing of full-thickness skin wounds, but their application currently requires two surgeries. The present study investigated whether it is possible to repair full-thickness skin defects and improve wound healing quality in a single surgery using Pelnac as an overlay of minced split-thickness skin grafts in a rat model. Methods A full-thickness skin defect model was established using male Sprague-Dawley rats of 10 weeks old. The animals were randomly divided into control and experimental groups in which Vaseline gauze and Pelnac, respectively, were overlaid on minced split-thickness skin grafts to repair the defects. Wound healing rate and quality were compared between the two groups. For better illustration of the quality of wound healing, some results were compared with those obtained for normal skin of rats. Results We found that using Pelnac as an overlay for minced split-thickness skin grafts accelerated wound closure and stimulated cell proliferation and tissue angiogenesis. In addition, this approach enhanced collagen synthesis and increased the formation of basement membrane and dermis as well as the expression of growth factors related to wound healing while reducing scar formation. Conclusions Using minced split-thickness skin grafts overlaid with Pelnac enables the reconstruction of full-thickness skin defects in a single step and can increase the healing rate while improving the quality of wound healing.
