the current study showed that the dermaroller was superior to the TCA CROSS (80%) in term of improvement of atrophic post acne scars as detected by photo evaluation (higher percentage of excellent improvement and percentage of improvement) and Goodman and Baron scale (higher percentage of patients having macular scars after treatment) however, no significant difference was detected as regard the patient satisfaction. We would recommend PCI over 80% TCA CROSS for treatment of rolling acne scars, PCI maybe more suitable for patients with a history of skin dyschromia because of a higher incidence of consequent postinflammatory hyperpigmentation with 80% TCA CROSS. TCA CROSS is better to be used in the treatment of ice pick acne scars where it is more suitable for patients who cannot tolerate pain, patients with fair skin, and patients with deep scars that cannot be fully reached with a dermaroller. In addition, it is less invasive and more economic modality especially in developing countries. More than one session is also recommended because greater improvement is achieved after multiple sessions with both techniques, especially PCI. Combining both procedures may have an even better response. أجريت الدراسة على 34مريض مصاب بندبات حب الشباب الضامرة مقسمين إلى مجموعتين المجموعة الأولى اشتملت على 19 مريض ومريضة تم استخدام جهاز سنفرة الجلد (الديرمارولر ) في علاج ندباتهم الضامرة بأجراء (4 جلسات وما بين كل جلسة والأخرى 4 أسابيع ) والمجموعة الثانية تم علاج ندباتهم بجلسات حمض الترايكلورواسيتيك 80% ( 5 جلسات بين كل جلسة والأخرى أسبوعين ) وقد تم تقييم المرضى عن طريق استخدام الصور قبل وبعد الجلسات ومدى رضي المرضى وحدوث اى أثار جانبية . وتلخصت النتائج فيما يلى : تحسن جميع المرضى المشمولين في الدراسة فى المجموعتين ولكن درجة التحسن فى الندبات كانت اعلي وبدلاله إحصائية فى المجموعة الأولى والتي تم علاجها باستخدام الديرمارولر بنسبة (59.8%) مقارنة بالمجموعة الثانية والتى تم علاجها باستخدام حمض الترايكلورواسيتيك 80% بنسبة (42.7%) ( 0.025 = p _value ) ولكن لم يكن هناك فروق ذات دلالة إحصائية فى درجة رضى المرضى بين المجموعتين وكانت المضاعفات أكثر فى المجموعة الثانية وبالذات فيما يخص التصبغ الجلدى بعد الجلسات.

Abstract Purpose The aim of this study is to evaluate the clinical outcome of single-incision flexor hallucis longus tendon transfer in chronic Achilles tendon rupture. Methods A prospective study of a series of cases of chronic Achilles tendon rupture that were treated with single-incision flexor hallucis longus tendon transfer, from April 2015 to December 2016. The study included 21 patients (15 men and 6 women), with mean age 40.3 ± 17.5 years. The average follow-up time was 15 (12–24) months. Flexor hallucis longus transfer was fixed with a titanium interference screw in an intraosseous calcaneal tunnel. Results The average operative time was 52.9 ± 8.7 minutes. The AOFAS-hindfoot score was significantly improved from the mean pre-operative value of 57.4 ± 10.3 to mean value of 95.3 ± 4.4 (p value 0.001). There was no effect on the big toe function. The complication recorded was one superficial wound infection which resolved by dressing and appropriate antibiotic coverage. All patients were satisfied with the results of surgery. Conclusions Single-incision flexor hallucis longus transfer for chronic Achilles tendon ruptures is a simple method with minimal morbidity and complications. The technique resulted in great patients’ satisfaction as well as excellent functional and clinical outcomes.
