INTRODUCTION Handling severe burn damages of the hand is a challenge of considerable interest. Long-range risks as hypertrophic scar and retraction could lead to deformities, possible loss of functionality, and a negative impact on the life's quality.1,2
Treatment for post-burn, hypertrophic scar, and tightness includes different non-operative treatment like a mechanistic compressing bandage, a silicon sheet, steroid injection, and laser therapy. These are considered as the first line of option and even in integration with an operation involving tissue extension, sequential skin eradication, skin grafting, and Z-plasties.3
Lipofilling has been utilized in multiple conditions such as reconstruction/augmentation and correction of hemifacial microsomia asymmetries. The usage of lipofilling in hand expands to diminish hypertrophic scars after traumatic injuries, in addition to skin regeneration as a cosmetic treatment.4
After a split-thickness skin grafting, patients with secondary post-burn scars found a marked increase in flexibility within 3-month follow-up, assessed by the Patient and Observer Scar Assessment Scale (POSA) adhering to a single fat grafting proceeding. Scar shape was changed, and the cases notified a respectable reduction in pain in the scar area.5
Nowadays, several studies have shown the beneficial effects of autologous fat grafting on scar contracture and skin quality in different body regions.6,7
Autologous fat grafting has become a process that could be performed as an adjunct procedure to the existing operative therapy, causing potential renewal impacts on the handled position and could decrease tightness and adherence.8
As the treatment of severe burn injuries to the hand represents a challenge of great concern, in the present work, we aimed to evaluate the effect of lipofilling in post-burn grafted hands regarding the functional and aesthetic outcome.
PATIENT AND METHODS Study design: This case serious study was conducted at Al- Azhar University Hospitals in the period from May 2019 to August 2020.
Study Population: Twenty patients with post-burn contracted grafted hands after new hand burn (time of burn was 2 months before fat injection). Patients were complaining of cosmetic and functional complications. All patients included in the study were suffering from a reduced domain of movement because of scar tightness or cosmetically dissatisfying scars but in a good physical case. But, smokers, poor compliance cases, as well as patients unsuitable for operation and even while the patient's joint capsule narrowness/joint toughness is the major reason for a reduced domain of movement, in addition to cases who have extensor deformities (Boutonniere deformity, Swan-Neck deformity, and Mallet finger deformity) are eliminated from the study.
Methods: After counseling all patients and explaining the operation purpose, after operation treatment, and also a potential risk, informed documented consent and photographs were obtained from all patients. Detailed background, specific and generic checks, and complete tests were implemented for the cases. All patients were managed with the same operative technique for autologous fat grafting and 6 months’ follow-up.
Preoperative assessment: Patients’ hand functionality evaluation: The before operation evaluation was implemented and involved: 1) Total Active Movement (TAM) evaluated using the stainless steel Goniometer, 2) Every finger was evaluated as a single identity through overall flection as well as extending. The TAM of a digit is calculated by supplementing the overall movement of whole the three joints inflection and subtracting the expansion disability from that. In accordance with the American Society for Surgery of the Hand (ASSH) method.9
A TAM worth of 2608 is Normal (Metacarpophalangeal (MCP) = 858, Proximal Interphalangeal (PIP) = 1108, Distal Interphalangeal (DIP) = 658):
Evaluation of patient contentment: The patient and observer scar assessment scale (POSAS)10 was given to whole cases before and after medication. They evaluate vascularity, pigmentation, density, comfort, flexibility, exterior area too, and merge case evaluations of pain, itching, color, toughness, density, as well as comfort.
Surgical procedure: All patients in this study were generally anesthetized. Fat harvesting and processing: Fat harvesting was done according to the Colman technique11 using a two-hole harvesting cannula with a blunt tip attached to a 50-ml Luer-Lok syringe Figure (1). Afterward, washing of harvested fat by a 20-cc syringe filled with normal saline was performed before fat transplantation according to Fabio Fantozzi's study.12 Figure 1: Pulling back on the plunger of a 50-cc syringe to create a slight negative pressure needed to harvest the fat.
Fat injection: was performed one month after healing of graft. A small 1 mm stab incision was performed over the burnt hand dorsum by a No. 11 blade, at a position near to the scar tightness. An infiltration cannula was put in and passed throughout the incision and softly redirected within several moves in a radial pattern, to make tubes for fat injection. Scar releasing was performed by a V-shaped canula. The 1 ml syringe tied to the cannula, allowed fat to be put in a radiating fashion, in the area under the skin, in small increases of 0.1–0.2 ml within every pass. The first 8 cases of burn scars treatment were injecting greater amounts that were directly distributed to the fingers or incomplete area by the operator's hand/finger. The last step was injecting more fat into the scar and fulness in density Figure (2). Small excess was carried out in the first 6 cases, however, averted throughout the following cases because we found that placement was very consistent and less possible to extrude from the space narrowness under the skin. All incisions were stitched using 5/0
Figure 2: (A,B) Fat injection made by 5 cc syringe connected to infiltration cannula.
Post-operative: Post-operative care concerning patient’s movement, sleep, medications, nutrition, activity, and incisions (Fat transfer entry points, Incisions of fat harvesting) was conducted to all patients.
Follow-up was done at 2 weeks, 1 month, 3 months, and 6 months. Digital photography has been taken for 1 month and 6 months. Statistics testing: measures were inserted in a Microsoft Excel data table (version 14.4.3, Microsoft Corporation, WA, and USA) and statistical tests were carried out utilizing GraphPad InStat v3 for Macintosh (GraphPad Software, Inc, San Diego, USA). Significance measurements (total active movement, and POSAS scores) were utilized. Statistics indication was made at a p-value of
RESULTS
The study included 20 patients divided into 14 females and 6 males with a mean age ± SD of 32.45 ± 11.74. 11 patients (55%) were right-handed, while 9 patients (45%) were left-handed. 7 patients (35%) were suffering from a 2nd-degree burn, while 13 patients (65%) were suffering from a 3rd-degree burn. The burn time ranged from 5.0 – 24.0 months with a mean ± SD of 8.05 ± 4.49. The burn mode was scald in 7 (35%) patients, and flam in 13 (65%) patients. All patients received a split-thickness (ST) skin graft. The injected fat ranged from (min.=5 ml to max.=15 ml) with a mean ± SD of 11.55 ± 2.63. All patients had burns to the dorsum of hand and fingers with physical limitation and tightness and aesthetic disfigure ments. Follow-up for graft healing was done after three months and 6 months after lipofilling.
Regarding the assessment of hand function, there was a statistical development throughout the total active movement. The before operation TAM developed from a medium of 146 to 1708 postoperatively. Preoperatively most cases (60%) were in the Good/Excellent class, with 40% in the Fair/ Poor class; following fat grafting, there was a change in their TAM group with 80% in the Good/Excellent additionally 20% in the Fair/Poor group class after the operation. In this study, there were 8 patients with TAM score preoperative 2600 (excellent) and 8 patients with a score of 2350 (good) they improve to a score of 2600, and 4 patients with a score of 2000 (fair) improve to score (2500).
Regarding the assessment of patient satisfaction (POSAS), pain, itching, scar color, volume, stiffness, and skin-softening were generally improved. There was mild improvement in itching and pain. (P-Value Regarding the assessment of doctor opinion (POSAS), vascularity, pigmentation, pliability, and pain relief were significantly improved (P-Value <0.001) Figure (4). There were statistically significant improvements in the total doctor opinion (POSAS) score (P-Value<0.001) Table (2) Figure (5). In addition, there were statistically significant improvements in the overall POAS score (P-Value <0.001) Table (3) Figure (5). Figure 6 and Figure 7 demonstrate two cases of our patient's pre and postoperatively. In the current study, no complications were encountered after fat grafting in 80% of cases. While in 20% of cases, multiple dehiscences, keloid formation, hypopigmentation, and poor patient compliance were reported Figure (8).

DISCUSSION
Fat grafting was utilized in the treatment of scars resulting in a tremendous impact on skin quality.13,14 Unfortunately, hand function is mostly affected by the resulting post-burn scar. Nowadays, fat grafting is increasingly accepted as adjuvant therapy in order to improve the quality of injured skin.15 The current study was conducted in the department the Plastic Surgery at al-Azhar University Hospital on twenty patients to treat post-burn scar contractures on the dorsum of grafted hands. All patients received one session of autologous fat graft with 6 months follow-up period. The clinical evaluation of the results shows improvement in stiffness, texture, thickness, elasticity, vascularity, and color of the treated skin as well as a reduction of the scar retraction. Fat grafting was done after complete healing of the skin graft. The donor area is selected in consultation with the patient. In this study, the donor areas were mainly the abdomen and thighs. Fat grafting was done under general anesthesia, only cutaneous and subcutaneous contracture are included after exclusion of any other deformities in hand joints either due to previous trauma or rheumatological diseases. Huang SH et al, choose the abdomen as a donor site in their study to assess neuropathic scar pain after using autologous fat that is preferable due to the abundance of fat and ease of access with the patient supine.16 The age of patients in this study was ranging between 6 to 60 years old by mean 32.45 ± 11.74 and the mode of the burn was scald in 7 patients and flam burn in 13 patients with a mean of 11.55 ± 2.63. The volume injected was proportional to the extent of scarring and surface area affected. In the present study, the total amount of intraoperative fat injected ranged from 5.0 – 15.0 ml with a mean ± SD 11.55 ± 2.63. Klinger et al. suggested that 1 mL AFG for each 3.5 cm 2 should be used and Piccolo et al. suggested 1.6–2.0 mL per 10 cm 2.5.14,17 According to the doctor's opinion in the current study post-operative follow up showed improvement of hand vascularity (color), skin thickness, and skin pigmentation overtime at (2 weeks, 1and 3 months) interval with a statistically significant difference at p-value <0.001*, <0.001* and <0.001*.Also, patients reported statistically significant differences regarding them during follow-up. Riyat et al, study made of a systematic review that assessed the efficacy of AFG in treating scar tissue, in 23 articles. A total of 1158 patients were assessed for improvement in scar characteristics including colour, thickness, volume, pain, and restoration of function at affected sites, following treatment. Positive outcomes were noted for all parameters and a significant improvement in AFG's analgesic effect was recorded in 567 out of 966 patients, P < 0.05.(18) In the current study according to the patient’s and doctor’s opinion, there was statistically significant better hand pliability at (2 weeks, 1and 3 months) follow up at p-value <0.001*and <0.001* respectively. A recent study including 40 patients, the majority with adherent postburn scars undergo autologous Fat Grafting found a significant increase in pliability at 3-month follow-up, measured by the Patient and Observer Scar Assessment Scale and the Cutometer following a single fat grafting procedure. Also, scar features were ameliorated, and the patients reported a significant decrease in pain related to the scar.5 In the present study according to the doctor’s opinion, there was a relief sensation during follow up at (2 weeks, 1and 3 months) intervals with a statistically significant difference at p-value <0.001* In addition patients experienced less pain and itching overtime during follow up with statistically significant difference at p-value <0.001*. In agreement with these results, Fredman et al. focused on the improvement of neuropathic pain in 7 patients with chronic, refractory neuropathic pain, who underwent fat grafting to burn scars and reported improvement of color, texture, contour, pliability, and itching. Six of seven patients had improvement in neuropathic pain after fat grafting.19 Also, Huang et al. demonstrated a rapid analgesic effect of neuropathic pain, just one week after treatment.(16) This was a significant improvement (P < 0.05), using the VAS and NPSI scores. In addition, Lisa et al. suggested that the ADSC create a microenvironment, following tissue regeneration, which encourages nerve release.20 Clinical evaluations of the patient were done according to Patient Observer Scar Assessment Scale (POASA) as it contains four main parameters (vascularity (color), pigmentation, pliability, and height. In our study, overall, POSAS score including (both patients and observer score) mean± SD was 84.20 ± 5.37, 56.45 ± 5.73and 31.75 ± 9.29 at 2 weeks, 1-month ad 3 months respectively with a statistically significant difference at p-value <0.001*. In the same regards Byrne, M et al. study on thirteen patients who were included in this analysis. The average time from burns and from the fat transfer was 2.3 years (10 months–3.9 years) and 9.1 months (3 months–1.3 years), respectively. There was a statistically significant improvement in TAM measurement. The total score, activity of daily living score, and satisfaction score of the MHQ also statistically increased following fat transfer. For scar assessment, the total score, and the overall score of POSAS improved significantly. Similarly, scores for scar color, scar thickness, scar stiffness, and scar regularity increased significantly.21 Also, Klinger et al. reported improvement in all POSAS parameters, both patient and observer after three months of follow-up. All these parameters were significant compared to controls except pain and itching.14 Despite the advantages of AFG, Riyat et al. reported complications in 14 patients from a total of 1158 patients who were assessed for improvement in scar after fat grafting. This included postoperative hematoma and infection, need for further AFG sessions, and surgical excision of scar tissue following unsuccessful treatment. However, in the current study, no complications were encountered after fat grafting.18 In this study, we notice that the aesthetic acceptance of our patients was inferior to the surgeon’s acceptance and was attributed to the non-realistic expectations of the patients despite well-informed pre-operative consultations. Eight patients (40%) responded as an excellent result while ten patients (50%) responded as good results and two patients (10%) responded as poor results. This is depending on the expectation of the physician and the patient improvement in the patient observer scar assessment scale.
CONCLUSION Overall, our data suggest autologous fat grafting was superior in post-burn atrophic scars as a good volume filler because of its filling character rather than its good effect on improving the quality of scars through the improvement of scar vascularity, pigmentation, skin thickness, pliability, pain, and itching.
