Humerus diafiz psodoartrozlarinin tedavisinde uyguladigimiz kilitli intrameduller civileme tekniginin klinik, radyolojik ve fonksiyonel sonuclari degerlendirildi. Calismaya, humerus diafiz psodoartrozu tanisiyla kilitli intrameduller civileme teknigi kullanilarak tedavi edilen 28 hasta (11 erkek, 17 kadin; ort. yas 50,3; dagilim 26-73 yil) alindi. Psodoartrozlu vakalarin 6’si hipertrofik, 22’si atrofik psodoartroz tipinde idi. Psodoartrozlu vakalarin 12’si sag, 16’si sol yerlesimli idi. Psodoartrozlu 28 vakanin 18’i tedavi oncesi ortalama 1,5 (1-3) basarisiz ameliyat gecirmis, 10’u konservatif yontemlerle tedavi edilmeye calisilmistir. Kilitli intrameduller civileme tum vakalarda antegrad, acik ve oymali yontemle uygulandi. Vakalarin hepsine kemik grefti ile grefonaj uygulandi. Fonksiyonel degerlendirme Hunter ve Constant-Murley kriterlerine gore yapildi. Hastalarin ortalama izlem suresi 36,2 ay (dagilim 7-43 ay) idi. Yirmisekiz psodoartroz vakasinin 26’sinda takiplerinde kaynama saglandi. Iki vakada kaynama gorulmedi. Ortalama kaynama sureleri 16,5 (11-25) hafta idi. Hicbir vakada cerrahiye bagli vaskuler problem gorulmedi. Vakalarin birinde ameliyat sonrasi radial sinir lezyonu gozlendi ve sinir lezyonunun kendiliginden iyilesmemesi uzerine hastaya tendon transferi yapildi. Hastalardan hicbirinde on-arka ve yan acilanma yok idi. Radyolojik olarak onemli rotasyonel deformite saptanmadi. Hicbir vakada cerrahiye bagli enfeksiyon gelismedi. Ameliyat sonrasi radyolojik degerlendirmede, uc vakada civi proksimal ucunun yuksekte kaldigi saptandi. Fonksiyonel degerlendirmede Hunter kriterlerine gore 21 vakada mukemmel, 7 vakada iyi; Constant-Murley skoruna gore 22 vakada cok iyi, 6 vakada iyi sonuclar alindi. Humerus diafiz psodoartrozlarinin tedavisinde kilitli intrameduller civileme ile yeterli fiksasyon ve erken hareket saglanmakta, tatmin edici klinik, radyolojik ve fonksiyonel sonuclar alinmaktadir. Locked intramedullary nailing results in treatment of humerus diaphyseal pseudoarthrosis The technique of intramedullary nailing in the treatment of pseudarthrosis of the humeral diaphysis clinical, radiological and functional results were evaluated. The study of pseudarthrosis of the humeral diaphysis were treated with the diagnosis of intramedullary nailing technique in 28 patients (11 males, 17 females; mean age 50.3, range 26-73 years) were included. Six of these cases were hypertrophic type and 22 of them were atrophic type pseudarthrosis. Twelve of the cases were on the right and 16 were on the left. From 28 cases with pseudarthrosis, 18 had a mean of 1.5 (1-3) failed surgeries and 10 receieved conservative methods before treatment. For all locked intramedullary nailing cases antegrad, front and carved techniques were applied. All patients underwent bone grafting. Functional evaluation was made according to the Hunter’s and Constan-Murley’s shoulder scoring system. The mean follow-up was 36.2 months (range 7 to 43 months). Twentysix of these 28 cases were succesfully treated and united. Pseudarthrosis was seen in two cases. The average duration of healing 16.5 (11-25) weeks, respectively. None of the cases had surgery-related vascular problems. Radial nerve palsy was observed in one of the cases after surgery and because nerve lesion did not improve Self-tendon transfer was performed on the patient. None of the patients had no anterior-posterior and lateral angulation. There was no significant rotational deformity radiologically. None of the patients developed surgery-related infection. In postoperative radiological evaluation, the proximal tip of the nail was found high in three patients. Functional evaluation according to the criteria Hunter 21 cases were excellent, 7 cases were good; Constant-Murley score 22 cases were very good, 6 cases were good. In according to treatment of pseudarthrosis of the humeral diaphyseal intramedullary nailing provided adequate fixation and early motion, satisfying clinical, radiological and functional results are obtained.
