Background/aim: Total hip arthroplasty (THA) is technically more difficult and has higher complication rates in patients with Crowe type 3-4 developmental dysplasia of the hip (DDH). Due to the difficulties and different treatment options, there is still no consensus on the optimal treatment. We aimed to evaluate the mid-term results of our patients who had undergone subtrochanteric femoral shortening Z-osteotomy. Materials and methods: This study included 37 hips of 29 patients with the diagnosis of Crowe 3-4 DDH between June 2010 and December 2016 and who underwent femoral shortening Z-osteotomy with cementless total hip arthroplasty. Acetabular component was determined according to the patient's age and functional capacity and all patients were operated with a posterior approach. Functional results, postoperative complications, Harris and visual analogue scale (VAS) scores were evaluated. Results: The average Harris hip score was 41.3 +/- 3.1 preoperatively and 84.7 +/- 4.3 postoperatively (p < 0.05). The mean preoperative hip pain score on the VAS was 7.9 (range: 6-9) and this was significantly lower at the last follow-up (mean: 3.4; range: 2-4) (p < 0.05). The final mean limb-length discrepancy was 1.3 cm. The average amount of femoral shortening was 3.2 cm. Regarding complications, 3 (10.3%) patients had dislocations. These patients underwent closed reduction. Sciatic palsy developed in 1(3.4%) patient. The patient was reoperated on for sciatic nerve dissection in the early period. Conclusion: Subtrochanteric shortening Z-osteotomy combined with cementless total hip replacement can be considered an effective and successful method in selected patients with Crowe 3-4 coxarthrosis.

Background/aim: Sleep disturbance and related improvement in quality of life as a result of arthroscopic repair in rotator cuff tear (RCT) patients can be considered as an important parameter. The aim of our study is to evaluate the rotator cuff by ultrasonography (USG) in the first postoperative year and to examine whether there is a difference between sleep disturbance and quality of life between cases of rupture and healthy patients. In addition, we aim to compare the preoperative and at least the first postoperative year's sleep disturbances and quality of life among patients who underwent arthroscopic RCT repair and to examine the effects of factors affecting this situation. Materials and methods: We retrospectively reviewed the records of patients who were operated on for RCT. In this process, 257 patients were examined and 76 patients who met the inclusion criteria were included in the study. The Pittsburgh sleep quality index (PSQI), Constant-Murley shoulder score (CSS), and Oxford shoulder score (OSS) were used to evaluate the results preoperatively and at the last control visit of each patient. In the USG performed in the postoperative first year, the rotor cuff was evaluated in terms of rerupture. Results: It was observed that 14 (18.4%) patients' rotor cuffs were reruptured and those of 62 (81.6%) patients were intact. The preoperative PSQI, CSS, and OSS values of the patients were calculated as an average of 10.79 +/- 3.58, 35.61 +/- 8.88, and 17.61 +/- 4.20 and the mean postoperative values were calculated as 5.45 +/- 1.68, 81.55 +/- 5.27, and 38.05 +/- 3.06, respectively. The postoperative PSQI value was statistically significantly lower in patients with tears of <1 cm (PSQI: 4.29 +/- 0.73) than in those with tears of 1-3 cm (PSQI: 5.50 +/- 2.17) and 3-5 cm (PSQI: 5.88 +/- 1.25) (P < 0.001). The mean CSS and OSS values were significantly higher in postoperative measurements for all tear types. According to the size of the tear, postoperative CSS and OSS values were statistically significantly lower in patients with tears of 3-5 cm (CSS: 78.59 +/- 4.50 and OSS: 36.18 +/- 2.47) than those with <1 cm (CSS: 85.43 +/- 2.14 and OSS: 40.57 +/- 1.55) and 1-3 cm (CSS: 83.21 +/- 5.35 and OSS: 39.07 +/- 2.94) tears (P < 0.001). Conclusion: In the USG performed in the postoperative first year, it was determined that the patients with healthy rotator cuffs recovered better than those with rerupture.

Background/aim: Pilon fracture is difficult to treat fractures due to many complications that can develop after surgery. To achieve the best results, different surgical approaches are used.In our study, we aimed to compare the functional results and complication rates of our treatments in patients treated with 3 different surgical tecniques.Materials and methods: 89 pilon fractures of 87 patients treated for pilon fracture were evaluated. Patients were examined in 3 different groups (one step, two step surgery and Ilizarov). Functional results, postoperative complications and ankle AOFAS scores were evaluated.Results: The mean AOFAS score of the all patients was 77.67. There was no significant difference between 3 surgical techniques (P = 0,880). While skin complication was not seen in patients who underwent double-stage surgery and Ilizarov (0%); It was seen in 6 (15.7%) patients who underwent single-stage surgery. Treatment results were found to be better in type 1 and type 2 fractures, while in type 3 fractures (P = 0.004).Conclusion: Despite the different surgical approaches and implants applied, no difference was found between the midterm ankle functional results of the patients. Two-stage surgery and Ilizarov is a safe and effective treatment approach to reduce morbidity and early complications in pilon fractures.

High tibial osteotomy (HTO) and unicompartmental knee arthroplasty (UKA) are widely used surgical options for the treatment of medial compartment knee oste
