Öğe Distraction lengthening of the proximal phalanx in distal thumb amputations(Turkish Society of Orthopaedics and Traumatology, 2015) Cansu, Eren; Ünal, Mehmet Bekir; Parmaksızoğlu, Fatih; Gürcan, SerkanObjective: Thumb amputation is a major cause of hand dysfunction, and the treatment for distal thumb amputations remains controversial. Although finger reconstruction methods using distraction lengthening are known to restore finger length and function, we found no reports in the literature regarding phalangeal lengthening in thumb amputations. We aimed to evaluate proximal phalangeal lengthening in thumb amputations at or near the interphalangeal (IP) joint. Methods: We retrospectively evaluated patients who had undergone distraction lengthening of the proximal phalanx of the thumb. All patients underwent osteotomy, either during the initial procedure or as a second-stage procedure. Distraction began 10 days after osteotomy with the use of an external fixator that remained in place until ossification of the gap occurred without bone grafting. Patients were evaluated using the QuickDASH score. Results: Fourteen patients with a mean age of 27 years and a mean follow-up period of 7 years were enrolled. The mean phalangeal lengthening achieved was 20 mm. Ossification occurred at all distraction sites, and the fixators were maintained for a mean of 85 days. The mean healing index was 42.5 days/cm. All 14 patients achieved the desired amount of phalangeal lengthening without major complications such as nonunion, premature union, or gross infection. Conclusion: For reconstruction in cases of distal thumb amputations, distraction lengthening of the proximal phalanx can be used to improve absolute length, web space, and grip distance. The technique is safe and effective, improves functionality/cosmesis, and offers a low complication risk.Öğe Functional results of limb salvage in below-knee type III C open fractures or traumatic amputations(Thieme Medical Publishers Inc., 2012) Parmaksızoğlu, Fatih; Ünal, Mehmet Bekir; Cansu, Eren; Köprülü, Ali Şefik; İnce, Yener; Yurga, EbruThis study presents the surgical and functional outcomes of below-knee total leg amputation and Gustilo type III C open fracture cases that were considered appropriate for salvage treatment according to a more proactive approach, despite being candidates for amputation according to the current scoring systems. Nineteen patients (21 legs) underwent replantation-revascularization surgery. At least Chen Grade II functional level was the aim. A limb salvage operation was performed in 21 legs in 19 patients (18 male, 1 female). The mean age was 28.5 years (range: 11 to 42 years). Six legs in four patients presented with total amputation, and 15 legs in 15 patients had Gustilo Type III C open fractures. A successful replantation/revascularization was performed in 20 legs, with a Chen Grade I and Grade II functional outcome in 3 and 17 legs, respectively. None of these patients were eligible for salvage operation according to currently used scoring systems. Limb-preserving surgery performed upon the assessment of local and general conditions of the patients with traumatic below-knee amputations or Gustilo Type III C open fractures seems to be a viable therapeutic option that can serve to achieve Chen Grade II functional level in most patients.Öğe Neglected lunate dislocation presenting as carpal tunnel syndrome(Taylor & Francis, 2015) Cansu, Eren; Heydar, Ahmed Majid; Elekberov, Anar; Ünal, Mehmet BekirMost of carpal tunnel syndrome cases are idiopathic, and secondary causes are so rare that can be easily missed. We present a patient with neglected undiagnosed lunate dislocation compressing on median nerve causing its signs and symptoms.Öğe Surgical treatment of lateral malleolar fractures using the compression cerclage system(American Podiatric Medical Association, 2016) Cansu, Eren; Ünal, Mehmet Bekir; Gürcan, Serkan; Parmaksızoğlu, FatihBackground: Lateral malleolar fractures (Weber type B or OTA 44-B) account for 60% of all ankle fractures. To achieve anatomic restoration, surgical stabilization provides better results than conservative treatment. Various fixation methods are available to treat these fractures; however, the best method is still unknown. Our objectives were to present a new, useful, and efficient surgical technique for stabilizing lateral malleolar fractures and to analyze the outcomes of patients treated with the compression cerclage system. Methods: The surgical technique consists of a Kirschner wire that is passed percutaneously and perpendicular to the fracture line, and a cerclage wire that is passed in a semi-circular fashion over the ends of the Kirschner wire on the lateral side of the bone, leaving loops on each side to allow bilateral compression while twisting both wires. We retrospectively evaluated patients treated with this technique, with or without additional fractures. Follow-up of <24 months and bilateral ankle fractures were the exclusion criteria. Fractures were examined clinically and radiologically in comparison to the uninjured side and were rated according to the criteria reported by McLennon and Ungersma. Olerud and Molander ankle score was used to evaluate functional outcome. Results: At the final follow-up, 15 out of 21 patients (9 women and 6 men; mean age, 48.2 years [range, 19-78 years]) were evaluated. The mean follow-up was 5.16 years (28-129 months). Five patients had an isolated lateral malleolar fracture; eight had lateral and medial malleolar fractures; and two had trimalleolar fractures. At the final follow-up, 11 patients were rated good functionally and four were fair, and all patients were rated good radiographically according to the criteria by McLennon and Ungersma. Mean Olerud and Molander ankle score was 93.3 (range, 80-100). Conclusions: The compression cerclage system provides good functional and radiological outcomes in patients with lateral malleolus fractures. This method is useful, safe, and efficient with minimum hardware. It can be applied through limited soft-tissue stripping, which is especially important in patients with a high risk for wound complications.Öğe The effect of early active movement following repair of extensor tendons in zone IV using three different suture techniques - A cadaveric study(Thieme Medical Publishers, 2021) Ilgaroğlu Zeynalov, Samir; İsmailoğlu, Abdulveli; Verimli, Ural; Alakbarov, Anar; Cansu, ErenPurpose The aim of this study was to investigate the effects of early active movement on the area repaired with three different suture techniques used in extensor tendon injuries in zone IV. Materials and Methods A total of nine cadaver’s 35 extensor tendons from 9 intact upper extremities were used in this study. The proximal and distal borders of the extensor tendons in zone IV were marked. The distance between the proximal and distal border was measured with a 0.5?mm precision tape measure and the mid-point was marked. Intertendinous connections were dissected and loop sutures were prepared for each extensor digitorum. Afterwards, force was applied to each digit along the tendon axis from the loops inserted into the extensor tendons, to measure the extensor forces required to extend the MCP joints to 0? with a hand scale. The flexor tendons of the digits were dissected at zone III, and loop sutures were prepared individually for the tendons to enable independent flexion for each digit. The force required to fully flex the digits was measured with a hand scale. The extensor tendons were incised transversely and repaired at the mid-point in zone IV with three different suture techniques (double Kessler, double figure of eight, running interlocking horizontal mattress (RIHM)). The extenxor tendon lengths in zone IV were re-measured for all digits after suturing. The predetermined forces required for full flexion and extension of the digits were applied to the repaired digits. After force was applied 20 times to each tendon, the gap formation was checked. Totally 200 flexion and 200 extension movements were applied to each finger with the help of a hand-held scale. Formation of 2-mm gap was failure criteria. At the end of the movements the extent of the gaps was recorded. In the absence of insufficiency at the repair site, 50 additional flexion and extension movements with double the previously recorded forces were applied to the tendons. Results There was a significant shortening of the extensor tendons after repair independent from the used suture technique. No significant gap formation was detected in all three suture techniques. Conclusion All three suturing techniques are reliable for early active movements following the zone IV extensor tendon repairs. Therefore, surgeons can choose one of those three suture techniques to repair extensor tendon injuries in zone IV.Öğe Treatment of osteonecrosis of the femoral head with free vascularized fibular grafting: Results of 7.6-year follow-up(Acta Orthopaedica et Traumatologica Turcica, 2016) Ünal, Mehmet Bekir; Cansu, Eren; Parmaksızoğlu, Fatih; Çift, Hakan; Gürcan, SerkanObjectives: The aim of this study was to determine long term follow up of the patients who had femoral head osteonecrosis and had been treated with free vascularized fibular grafting. Patients and methods: We retrospectively reviewed 28 hips of 21 patients who had undergone free vascularized fibular grafting for the treatment of osteonecrosis of femoral head. There were 16 male and 5 female patients. The mean age of the patients at the time of surgery was 30.7 years (between 15 and 53 years). The mean follow-up time was 7.6 years (between 5 years and 9.2 years). Results: During follow-up, one patient died because of leukemia, and one patient was lost. The remaining 26 hips of 19 patients were evaluated. According to the Ficat classification, at the time of surgery, 17 hips were in grade 2 and 9 hips were in grade 3. The post-operative Harris hip scores in grade II disease were excellent in 12 patients, good in 3 patients, and fair in 1 patient. In grade III disease, 1 patient was excellent, 5 patients were good, and 1 patient was fair. There was a significant increase in HHS scores (61 ± 9.7 vs 84 ± 17.8, p < 0.001). Conclusion: Free vascularized fibular grafting yields extremely good results, particularly in pre-collapse stages of disease in young patients. The operation time does not mark increased if the surgical team is “familiar” with the procedure, and the residual fibular defect of the donor site does not impair the functions of daily livingÖğe Treatment of osteonecrosis of the femoral head with free vascularized Şbular grafting: Results of 7.6-year follow-up(Turkish Assoc Orthopaedics Traumatology, 2016) Ünal, Mehmet Bekir; Cansu, Eren; Parmaksızoğlu, Fatih; Çift, Hakan; Gürcan, SerkanObjective: The aim of this study was to determine long-term follow-up results of patients with femoral head osteonecrosis who were treated with free vascularized fibular grafting (FVFG). Methods: The results of 28 hips of 21 patients (16 male, 5 female) who underwent FVFG for treatment of osteonecrosis of the femoral head were retrospectively reviewed. Mean age of patients at time of surgery was 30.7 years (range: 15–53 years). Mean follow-up duration was 7.6 years (range: 5–9.2 years).
