“…1 Several studies have demonstrated a close correlation between the BA and the carrying angle values 6,21,33 and concluded that the measurements of this angle after fracture reduction could be a reliable predictor for the final carrying angle. However, Mohammad et al 14 concluded that the association between the BA and the Figure 4 The humerus-elbow-wrist angle was measured on anteroposterior radiographs, reflecting the outline of the upper extremities. 19 To measure the humerus-elbow-wrist angle, 2 transverse lines (proximal and distal) were drawn across the humerus connecting the medial and lateral cortices, and 2 lines (1 proximal and 1 distal) were drawn across the forearm connecting the medial cortex of the ulna and the lateral cortex of the radius.…”

“…Both angles can alter with the amount of rotation and therefore correlation between Baumann angle and clinical elbow axis is poor in case of marked malrotation [4,6,14,18,78]. Other authors found the Baumann angle to be an inaccurate indicator of the carrying angle [66].…”

Closed reduction and percutaneous pinning techniques for displaced supracondylar fractures of the humerus in children (Gartland type III) have overcome disastrous ischemic complications and long inpatient treatment. Closed reduction of those highly unstable fractures and the demanding pin placement itself are potential sources of failure for the inexperienced reflected by the rate of cubitus varus which is still about 5-15% in recent series. Rotational primary and residual displacement has to be appreciated to prevent permanent cosmetic deformity. Malrotation is the major source of instability since bicolumnar support is lost which allows the distal fragment to tilt. Biomechanically tested better stability of crossed medial and lateral pins in comparison to two parallel lateral pins does not seem to be of practical importance. The risk of ulnar nerve injury by medial-pin fixation is not outweighed by significantly better clinical result. The rate of iatrogenic nerve injuries is 3-16% with the ulnar nerve being the most susceptible due to inadvertent pinning. Despite a high recovery rate, they are a nuisance for the patients. Fracture-related peripheral neuropathies have an incidence of 10-17%. With rare exceptions, concomitant nerve lesion recover spontaneously within a time range of 1-4 months. There is still controversy regarding the management of a post reduction pink, warm but pulseless hand with adequate capillary refill. Simple observation and conservative management lead to a favorable clinical outcome in most cases but cold intolerance or exercise-induced ischemic symptoms are a potential sequel.

“…[1][2][3] The angle between the capitellar physis and the humeral shaft on the lateral x-ray of the elbow, the lateral capitellohumeral angle (LCHA), can similarly be used to assess sagittal plane alignment. 5 Thus, many radiographs of the elbow in this setting are taken with the x-ray beam at an imperfect angle for optimal measurement. 5 Thus, many radiographs of the elbow in this setting are taken with the x-ray beam at an imperfect angle for optimal measurement.…”
