Comparison of Expandable and Locked Intramedullary Nailing for Humeral Shaft Fractures
(Cureus Inc, 2021) Akdemir, Mehmet; Biçen, Ahmet Çağdaş; Ozkan, Mustafa; Ekin, Ahmet
Introduction In this study, we clinically and radiologically investigated whether the application of expandable nails for surgical treatment of humeral shaft fractures has an advantage over locked intramedullary nails. Methods Patients treated with intramedullary fixation due to humeral shaft fractures in our clinic were investigated retrospectively. Patients with fractures of type 12A and 12B according to the AO classification in the middle 1/3 shaft region of the humerus were divided into two groups as those receiving fixation with expandable nails and with locked intramedullary nails. The union rate, union time, Q-DASH scores, duration of surgery, and complication rates were statistically compared between the two groups. Results The study included 38 patients with clinical follow-up from among 47 patients; 20 patients received fixation with locked intramedullary nails and 18 with expandable nails. The mean age of the patients was 56.92 (1991) years and 53% (n=20) were men while 47% (n=18) were women. During statistical evaluation, a statistically significant difference was found between the groups for union (100% and 72.2%) and complication rates (6% and 13%). More union and lower complication rates were found in patients treated with locked intramedullary nails. In comparing the mean of surgical times (71.1 and 30.2 min), expandable nails had a shorter surgical time. However, there was no statistically significant difference between the union time and Q-DASH scores between the two groups. Conclusion Locked intramedullary nails are a better fixation method than expandable nails due to the low complication rate and high rate of union. However, due to shorter surgery time, expandable nailing is an alternative method in limited cases.

Comparison of Single- and Double-Plate Fixation Techniques in the Treatment of Nonunions of the Humeral Shaft
(Atha Comunicacao & Editora, 2022) Akdemir, Mehmet; Biçen, Ahmet Çağdaş; Ozkan, Mustafa
Introduction: Humerus shaft fractures may be treated conservatively or surgically. In 2.5% to 13% of cases, nonunion is observed, and it leads to severe pain and morbidity. Plate osteosynthesis has become popular in the treatment of nonunion of the humeral shaft. In this study, we compared the clinical outcomes of patients with humerus shaft nonunion whom we treated with single- or double-plate fixation. Materials and Methods: Fifty-three patients diagnosed with aseptic humeral shaft nonunion and treated with plate fixation were included in the study. Patients were evaluated according to the number of plates (single vs. double plates). The two groups were subjected to statistical evaluation according to their clinical and radiographical results. Results: The average age of the patients was 53 years (range: 1-86); 28 (52.8%) were female and 25 (47.2%) were male. The union rate was 90.32% for single plate and 90.91% for double plate fixation. There was no statistically significant difference between single and double plates in the clinical and radiographical results (union time, union rate, Q-DASH score) (p > 0.05). There was a significant correlation between age and union times / Q-DASH scores according to the Spearman correlation test (p < 0.05). Transient radial nerve neuropraxia developed in 2 patients and 1 patient suffered from an infection that was treated with debridement and antibiotic therapy. Conclusion: In our study, similar good results were obtained with single and double plates. In treatment of humeral shaft nonunions, a second plate is not needed if enough stability is provided with single plate fixation.
Two- Stage Treatment of Extremity Deformities Associated With Thrombocytopeniaabsent Radius Syndrome
(Turkish Assoc Orthopaedics Traumatology, 2022) Akdemir, Mehmet; Bicen, Cagdas; Ozkan, Mustafa
Objective: The aim of this study was to evaluate the results of 2-stage treatment of upper and lower extremity deformities in patients with thrombocytopenia absent radius syndrome. Methods: Four patients (3 female, 1 male) with a mean age of 1.8 years (range 1-4) were included in the study. The patients were followed up for an average of 5.5 years. All 4 patients had bilateral radial longitudinal deficiency, whereas only 2 patients had bilateral fixed knee contractures. A 2- stage surgical procedure was implemented. The surgical procedure performed for radial longitudinal deficiency consisted of distraction with an Ilizarov frame in the first stage, followed by centralization performed in the second stage. Knee contractures were first treated using an Ilizarov frame, followed by a hamstring tendon transfer in the second procedure. Radiological evaluation of the radial longitudinal deficiency was done by measuring hand-forearm angle, hand-forearm position, and ulnar bowing preoperatively and at postoperative follow-ups. Knee contracture was evaluated by measuring the angle preoperatively and at postoperative follow-ups. Results: The mean hand-forearm angle values of patients at preoperative assessment, early postoperative period, and at the last follow-ups were 82.60, 5,80, and 11.10, respectively (P <.001). The hand-forearm position values were -14.25 mm, +11, and +7.1 mm, respectively (P <.001). The ulnar bowing values were 7.3 degrees, 4.5 degrees, and 2.9 degrees, respectively (P <.001). Recurrence of the radial longitudinal deficiency deformity requiring surgery occurred in 1 patient. In the other 3 patients, some deformity recurred but did not require surgical intervention. In addition, 1 patient with knee flexion contracture had a recurrence of the contracture that did not require surgical intervention. There was no circulatory disorder or skin necrosis in the lower or upper extremities of the patients. Conclusion: This study has shown us that two-stage treatment is a reliable method for lower and upper extremity deformities accompanying thrombocytopenia absent radius syndrome. However, recurrence is still a major problem. Level of Evidence: Level IV, Therapeutic Study
