Aim: The aim of the study was to assess the correlation of CE angle to the ratios of medial hip joint space width and femoral head diameter to acetabular width.

Material and metod: Measurements were done on 196 AP pelvic radiographs of 10 years old and 20 years old males and females obtained with “siemens lconos r 200 axion^®”. The patients were placed in the supine position with their hips extended and internally rotated 15°. Medial hip joint space width (mJSW), CE angle, femoral head diameter (FD) and acetabular width (AW) were measured. The intraobserver reproducibility was assessed by a randomly chosen subset of 50 radiographs and these were read 1 month apart. The levels of agreement were qualified using the intraclass correlation coefficient. The ratios of mJSW to AW and FD to AW were calculated.

Results: Mean CE angles in 10 years old females and males were 33.87±3.64 ve 32.74±4.21 degrees respectively. CE angle was correlated to mJSW/AW in 10 years old females (r = − 0.446, p=0.043). CE angle was not correlated to mJSW/AW in 10 years old males (r = − 0.293, p=0.146). CE angle was not correlated to mJSW/AW in 20 years old females while CE angle was correlated to mJSW/AW in 20 years old males (r = 0. 694, p=0.001). CE angle was correlated to FD/AW only in 20 years old males (r=0.553, p= 0.002).

Discussion: Ratios of medial hip joint space width and femoral head diameter to acetabular width are not correlated to CE angle in both preadelocent and postade-locent terms depending on sex. The expected inverse correlation of these parameters to CE angle was not dedected, so these parameters can be used in radiologic assessement of subluxation of the hip and acetabular dysplasia together with CE angle.

Aim: The aim of this study was to compare the treatment results of distal tibia shaft fractures treated with intramedullary nails with two different distal lockings and medial locking plates.

Patients and Method: Sixty-four patients with distal tibia fractures (4 to 11 cm proximal to the plafond) were operated with either unreamed intramedullary nails with medio-lateral distal locking (group A) or unreamed intra-medullary nails with both medio-lateral and antero-posterior lockings (group B), or medial locking plates (group C). There were 22 patients in group A, 22 patients in group B and 20 patients in group C. Mean age was 48.53±17.07 years. Mean follow-up was 26.68±7.02 months. At latest follow-up groups were compared for union time, malunion (defined as more than 5 degrees of angulation in any planes and/or any rotation and/or more than 5 milimeters of shortening), and delayed (lack of healing within 3 months) or nonunion (lack of healing within 6 months). Uninon was defined as healing of at least three of four cortices on AP and lateral radiographs.

Results: Mean union time was 17.45±4.22 weeks in group A, 16.71±4.90 weeks in group B and 15.73±3.26 weeks in group C. There was no significant difference between groups regarding union time. (p> 0.05) Malunion as defined was dedected in 4 patients in group A, in 4 patients in group B and in 1 patient in group C. There was no significant difference between groups regarding malunion rates. (p> 0.05). Delayed or non union was dedected in 6 patients in group A, in 5 patients in group B and in 1 patient in group C. There was no significant difference between groups regarding delayed or non-union. (p> 0.05). Two nonunions in group A and one nonunion in group B had to be treated with exchance reamed nailing. One infected nonunion in group C had to be treated with circular external fixation.

Conclusions: The results of surgical treatment of distal tibia fractures are similar with these three diifferent methods. Although malunion and delayed or nonunion rates are lower with medial locking plates, this is not significant.
