Role of Critical Shoulder Angle in Degenerative Type Rotator Cuff Tears: A Turkish Cohort Study.

BACKGROUND This retrospective study investigated the association between the critical shoulder angle (CSA) and the development of full-thickness rotator cuff tears (FTRCTs) in the Turkish population. The CSA is an imaging parameter that quantifies the relationship between the inclination of the glenoid and the lateral extension of the acromion in the coronal plane. The CSA is an anatomical measurement, and higher CSA values have been associated with an increased incidence of FTRCTs. However, there is a lack of data on CSA regarding the Turkish population. MATERIAL AND METHODS In this study, CSA measurements were recorded in 2 groups: 50 patients with FTRCT who had arthroscopic repair (group 1) and 50 age- and sex-matched individuals with no FTRCT detected by magnetic resonance imaging (group 2). Sex, age, affected side, dominant side, and smoking status were recorded for each patient. The CSA measurements of the affected sides were performed on true anterior-posterior view radiographs. RESULTS The results showed a statistically significant difference between the mean CSA values of group 1 (37.48°) and group 2 (33.53°), P<0.001. CSA values of 36 and above had a sensitivity of 73.58%, specificity of 74.47%, positive predictive value of 75%, and negative predictive value of 74.47% for detecting FTRCT. CONCLUSIONS CSA measurement on radiographs is a useful diagnostic tool in the Turkish population, and an above-average CSA value is associated with a significantly increased incidence of degenerative-type FTRCT.

Midterm treatment results of congenital dislocation of the knee in 14 knees of nine cases.

Patients with congenital dislocation of the knee (CDK) should be promptly treated surgically if conservative measures fail. This study aimed to achieve a better understanding of the diagnosis and management of CDK through sharing our experience and contributing to the existing literature. Nine patients with a total of 14 knees were included in the study. All patients except one were initially treated with gentle manipulation and serial casting. Surgery was performed on patients in whom sufficient joint mobility could not be achieved. Active and passive range of motion of the knees and functional outcome were measured. Of the 14 knees, five were classified as first grade, four as second grade and five as third grade. The mean age of the patients was 4.09 months and the follow-up period was 70 months. The initial mean flexion angle (MFA) was 18.2° (0-90) and the mean extension angle (MEA) was 8.2° (0-15). At the final follow-up, the mean MFA was 109.2° (80-140) and MEA was -2.85° (0 to -10). No patient had instability by the final follow-up. The results were classified as excellent (5 knees), good (5 knees) and moderate (4 knees) according to outcome assessment criteria. The functional outcomes were classified as excellent (7 knees), good (3 knees) and fair (4 knees) according to the functional outcome scoring. Treatment of CDK should be started in the first days of life, and if the desired functional outcome cannot be achieved through conservative treatment, surgical treatment should be planned without delay.

Using e-scooters: An easy way to get home or a nightmare? An orthopedic perspective on e-scooter accidents.

BACKGROUND: The percentage of e-scooter use quickly escalated in our community due to its convenience, low cost, and eases of use. The number of accidents causing high-energy traumas has also increased. This study aims to describe the demographic char-acteristics and fracture patterns of patients admitted to the emergency department following an e-scooter accident and to identify common, correctable factors that increased the likelihood of accidents. METHODS: Between January 2022 and August 2022, 43 patients (20 females and 23 males) who were admitted to the emergency department after an e-scooter accident and developed extremity fractures were included. The patients were divided into 2 groups those treated surgically and conservatively. Parameters such as the time of the accident, education level of the user, alcohol use, e-scooter malfunction, and compliance with traffic rules were evaluated. RESULTS: Accidents that led to treatment by surgery mostly occurred between 11 pm and 7 am. Surgically treated patients were mostly high school graduates. Alcohol use and recreational scooter use rates were statistically higher in the operated patients when compared to patients who were treated conservatively. The number of patients who reported a malfunction in the e-scooter was significantly lower in the operated group than in the conservative group. The rates of accidents due to non-compliance with traffic laws, driving at full speed of the e-scooter, use on the driveway, and presence of wet ground at the time of the accident were higher in the surgically treated patient group. Surgically treated patients also had a higher rate of being 1st time e-scooter users. CONCLUSION: Although governments have introduced many regulations regarding e-scooter use, the current situation seems insufficient in solving the problem. E-scooter users should be further educated about the associated risks. Authorities should tighten their supervision of scooter rental companies and drivers. Nighttime usage conditions should be reviewed, and the use of alcohol should be controlled. The use of helmets should be mandatory. If such regulations are tightened, accident rates can be reduced or high-energy impacts from existing accidents can be avoided. The results suggest that experienced, slow, non-alcoholic, and rule-abiding drivers require less operative treatment. This article will hopefully raise awareness and improve e-scooter regulations.

Diagnosis and Treatment Planning of Developmental Hip Dysplasia: Evaluation of Care Practices of the Members of the Turkish Pediatric Orthopedics Association.

OBJECTIVE: Developmental dysplasia of the hip is one of the most important causes of childhood disabilities. Although there are accepted treatment algorithms for developmental dysplasia of the hip, diagnosis and treatment approaches can show variations in the management among physicians. This study aimed to develop a diagnosis and treatment algorithm for developmental dysplasia of the hip according to the preferences of members of the Turkish Pediatric Orthopedics Association. MATERIALS AND METHODS: An interview by telephone call was made with 76 orthopedists (group 1: more experienced 39 physicians, group 2: less experienced 37 physicians) who are members of the Turkish Pediatric Orthopedics Association. Participants were q uesti onnai red ab out their demographic information, experiences, diagnostic criteria that they use for developmental dysplasia of the hip, and treatment approaches to patient scenarios of different ages. RESULTS: Most of the participants recommended universal screening at the age of 4 weeks. It was observed that the most significant physical examination finding was limited hip abduction, and the most frequently used radiographic evaluation on x-ray was acetabular index measurement. The most frequently used description for dysplasia was found as acetabular index >30°. CONCLUSIONS: Although there are some differences among orthopedists in the diagnosis, treatment, and follow-up approach of developmental dysplasia of the hip, there was no significant difference according to the experience-based grouping. The treatment algorithm, which was created with the most frequently given answers, was designed, which we think may be beneficial for pediatricians and orthopedists.
