    Closed Extensor Indicis Proprius Tendon Rupture Presenting Mass Clinic on Dorsal Side of the Wrist
    (Modestum Ltd, 2013) Kutahya, Harun; Gulec, Ali; Acar, Mehmet A.; Guzel, Yunus; Karalezli, Mustafa N.; Toker, Serdar
    A 28 years old male constructor referred to our clinic for a mass on the dorsal side of the left wrist. He has constricted his hand to the plaster cast machine in hyperflexion posture one month ago and swelling complaint has begun one week ago. MRI revealed tenosynovitis. A wide organized hematoma was appeared in the 4th extensor compartment in the surgical exploration of the patient and it was observed that extensor indicis proprius tendon has detached from the musculotendineous region. Common extensor tendon of the second finger was intact. Tenodesis to the distal end of the ruptured tendon to the intact common extensor tendon by side to side surgical suture technique was performed. There were complete extension in the 2nd finger at the 2nd month after the surgery.

    Comparison of monoplanar versus biplanar medial opening-wedge high tibial osteotomy techniques for preventing lateral cortex fracture
    (Springer, 2017) Turkmen, Faik; Kacira, Burkay K.; Ozkaya, Mustafa; Erkocak, Omer F.; Acar, Mehmet A.; Ozer, Mustafa; Toker, Serdar
    The purpose of this study was to investigate the mechanical strength of both monoplanar and biplanar medial opening-wedge high tibial osteotomy (MOWHTO) procedures and assess the risk of lateral cortex disruption for both techniques. Twelve synthetic tibia models with cortical shells were used as test models. Saw cuts for monoplanar MOWHTO and biplanar MOWHTO were generated on the test models in equal numbers (n = 6 for both groups). Wedge opening load and wedge gap distance were evaluated via compressive tests. The mean gap distance just before the lateral cortex fracture in the monoplanar group was 14.7 +/- 2.9 mm, which was significantly narrower than that in the biplanar group of 19.1 +/- 2.0 mm (p = 0.015). The mean load just before the occurrence of lateral cortex fracture of 32.4 +/- 3.2 N in the monoplanar osteotomy group was significantly lower than that in the biplanar osteotomy group of 111.8 +/- 9.3 N (p = 0.009). Performing a MOWHTO via the biplanar rather than the monoplanar technique allows larger-sized wedges to be opened with less risk of lateral cortical fracture. Thus, larger gaps can be opened and higher angle corrections can be achieved using the biplanar osteotomy procedure. From a clinical viewpoint, the biplanar osteotomy technique reduced the risk of lateral cortical hinge fracture during MOWHTO.

    A new diagnostic parameter for patellofemoral pain
    (E-Century Publishing Corp, 2015) Turkmen, Faik; Acar, Mehmet A.; Kacira, Burkay K.; Korucu, Ismail H.; Erkocak, Omer F.; Yolcu, Bayram; Toker, Serdar
    Purpose: Q-angle measurement procedure have not been well standardised. There is a lack of consensus about subject position and knee flexion angle while measuring the Q-angle. Morover Q-angle value which obtained in a single position is a static value and gives an information about the subject's current position. The aim of this study is to obtain a more significant parameter which includes different postures (supine, standing, sitting) and different knee flexion angles instead of a single Q-angle in a fixed position. At the same time this parameter must be functional and dynamic, not a static value like Q-angle. We named this parameter as Delta Q. Methods: Our study was applied on case and control groups. All subjects in both groups were male. Case group was consisted of 14 subjects who had patellofemoral pain. Control group was consisted of 14 subjects who had normal knees and normal lower extremities with no reported knee problems. We obtained 3 different Q-angle values and 3 different Delta Q values for each subject in both groups. Pearson correlation analysis was used for investigation of continuous variables in normal distribution, Spearman correlation analysis was used in abnormal distribution. t test was used in the comparison of values. Logistic regression analysis(forward conditional mod) was used for detecting of determinants of pain. Results: Delta Q1s of both groups were found as the only statistical significant predictive value for patellofemoral pain. Conclusion: There is not an agreement about a standardised q-angle measurement procedure in the literature. Moreover, present procedures provide information about a single and fixed position. In this situation Q-angles which obtained in these fixed positions are static values. We think that we can overcome these problems with this new value. Delta Q contains multiple q-angles and gives information about all. Also it is a dynamic value for being oriented to position change. Therefore, Delta Q is an useful indicator for evaluating patellofemoral pain.

    Reconstruction of multiple fingertip injuries with reverse flow homodigital flap
    (Elsevier Sci Ltd, 2014) Acar, Mehmet A.; Guzel, Yunus; Gulec, Ali; Turkmen, Faik; Erkocak, Omer F.; Yilmaz, Guney
    Aim: Hand trauma may lead to multiple fingertip defects, causing functional restrictions. We evaluated the use of reverse-flow homodigital flap reconstruction of the distal phalanx and pulp defects associated with multiple finger injuries. Methods: We retrospectively evaluated 11 male patients who presented at our emergency department (January 2011-March 2013) with multiple fingertip injuries and who were treated with a reverse-flow homodigital flap. Evaluations included age, sex, defect size, flap survival rate, complications, cold intolerance, two-point discrimination, range of motion (ROM), quick disabilities of the arm, shoulder, and hand (DASH) score, and return to work time. Results: Completely, 22 reverse-flow homodigital flaps were applied to at least two fingertip injuries at the distal phalanx. Ten flaps survived postoperatively. The exception was partial flap loss on one finger. The mean follow-up was 14.2 months. At the final follow-up, the mean static two-point discrimination value was 10.3 mm. Mean ROMs of interphalangeal joints were 65.31 degrees (distal) and 105.77 degrees (proximal). Donor sites were covered with full-thickness skin grafts from the wrist or antecubital area. There were no complications related to the donor site and no development of cold intolerance in any finger. The mean quick DASH score was 4.12. All patients returned to work in an average of 8.3 weeks. Conclusions: The reconstruction of multiple fingertip injuries with reverse-flow homodigital flaps is a safe, effective method that can be combined with other local finger flaps. These flaps can be applied to two consecutive fingers without reducing finger length or function. (C) 2014 Elsevier Ltd. All rights reserved.
