Comparison of lateral arm flap and posterior interosseous artery flap for soft tissue reconstruction of the elbow.

BACKGROUND: The study aimed to evaluate and compare the two different flap techniques used for the reconstruction of soft tissue defects in the elbow region: the lateral arm flap (LAA) and posterior interosseous artery (PIA) flap. METHODS: The retrospective study included 12 patients who underwent surgical treatment for soft tissue defects between 2012-2018 at the clinic. The study evaluated demographic data, flap size, operating time, donor site, flap complications, number of perfora-tors, and functional and cosmetic outcomes. RESULTS: Results showed that patients who underwent PIA flap had significantly smaller defect size than those who underwent LAA flap (p<0.001). However, there were no significant differences between the two groups (p>0.05). Patients who received PIA flaps had significantly lower QuickDASH scores, indicating better functional results (p<0.05). The operating time was significantly shorter in the PIA group than in the LAA flap group (p<0.05). Additionally, the range of motion (ROM) of the elbow joint was significantly higher among the patients who received the PIA flap (p<0.05). CONCLUSION: The study concludes that both flap techniques are easy to apply depending on the surgeon's experience, have low complication risk, and provide similar functional and cosmetic results in similar defect sizes.

Center-edge angle values in healthy children between 5 and 14 years old in Turkey.

OBJECTIVE: The aim of this study was to determine the center-edge angle (CEA) values according to age, gender and side in healthy children between 5 and 14 years old in Turkey and to find out the angular limit values for mild and severe dysplasia. METHODS: The data pool that was gathered to investigate the frequency of hip dislocation in children between 6 months and 14 years old in Turkey was used. The data pool consists of pelvis and lower abdomen radiographs obtained for reasons other than hip dysplasia. Lower abdomen/pelvis radiographies of children between 5 and 14 years old were extracted from the data pool and were evaluated. Distribution of CEA values according to age, gender and side was examined. Measurements were performed by a single investigator on computer by using a standard method. Reliability of the measurements was tested by three different investigators on randomly selected films by using the standard method. RESULTS: CEA values of 3192 hips of 1596 children, who had no hip pathology, were measured. Mean CEA value was found as 26.2°±5.5°. The mean CEA was 26.2°±5.3° in males (%54) and 26.2°±5.7° in females (%46) (p=0.224). Mean values for the right and left hips were 25.7°±5.4° and 26.6°±5.6°, respectively. CEA value of 449 (14%) hips of 333 (20.8%) children was at the limit of mild dysplasia and CEA value of 70 (2.2%) hips of 58 (3.6%) children was at the limit of severe dysplasia. CEA values had increased by age and mild and severe dysplasia limits were determined for every age group. CONCLUSION: The mild and severe dysplasia values that are defined according to ages in Turkish population will guide the investigators in the diagnosis, follow-up and treatment planning of developmental dysplasia. LEVEL OF EVIDENCE: Level IV, Diagnostic Study.

A comparison of the effects on postoperative bleeding of the intra-articular application of tranexamic acid and adrenalin in total knee arthroplasty.

OBJECTIVE: To compare the efficacies of intra-articular applications of tranexamic acid and adrenaline on postoperative bleeding after total knee arthroplasty. METHODS: The single-center, retrospective, controlled study was conducted at Selcuk University , department of orthopedic surgery and comprised data of patients who underwent primary, unilateral, cemented total knee arthroplasty between July 2012 and December 2014. Group 1 had received tranexamic acid 1g after closure of articular capsule. Group 2 had received adrenalin. Group 3, the control group, received no medication intraarticularly after total knee arthroplasty. The amount of blood collected in the drain and postoperative alterations in haemoglobin and haematocrit values were compared. RESULTS: Of the total 90 subjects, there were 30(33.33%) in each of the three groups. The decrease of haemoglobin and haematocrit values in Group 1 was statistically significant compared to both Group 2 and Group 3 (p<0.05). The amount of blood collected in the drains was remarkably lower in Groups I and 2 compared to Group III (p<0.05). No deep venous thrombosis or pulmonary emboli were encountered across the sample. CONCLUSIONS: Intra-articular administration of tranexamic acid was found to be beneficial and safe for the achievement of effective haemostasis after total knee arthroplasty.
