Introduction: Application of dynamic hip screw (DHS) implant for the treatment of unstable
intertrochanteric fractures continues to raise concern related to risk of lag screw cut-out with or without
subsequent damage to the acetabulum. Measurement of tip-apex distances (TAD) has been recommended to
guide the optimal placement of lag screw and to predict subsequent risk of screw cut-out. In this study, the
value of TAD was evaluated to verify its usefulness. Methods: This is a retrospective study of 33 consecutive
patients with intertrochanteric fracture treated with DHS. Demographic data of the patients were traced
from their case notes. Post-operative radiographs were reviewed by focusing on measurement of TAD on
anteroposterior and lateral radiographs. Radiographs at one year follow-up were reviewed to depict any
fixation-related failure or complication. Results: Fifty two percent of patients did not achieved the
recommended TAD of ≤ 25mm. The mean post-operative TAD was 25.9mm and elderly patients were likely
to achieve TAD of ≤ 25mm. The overall complication rate of 6% was attributed to screw cut-out in two
cases. The unstable left-sided fracture was identified to be a potential risk for screw cut-out or migration.
Conclusion: TAD is a valuable measurement to guide optimal placement of lag screw during DHS fixation of
intertrochanteric fracture.

This is a cross-sectional study of 37 patients with AO type C (complete intra-articular) fractures
of the distal radius, evaluating the functional, anatomical, and patient rated outcomes one year after primary
fixation with a volar locking plate. Methods: Functional outcomes were assessed based on the grip strength, and
the range of motion of forearm and wrist. Anatomical outcomes were assessed based on the radial inclination,
radial height, volar tilt, and articular step or gap. Patient rated outcome was measured with a Disability of
arm, shoulder and hand (DASH) questionnaire. Results: One year after surgery, 24 (64%) patients achieved good
and excellent anatomical results, and DASH scores were acceptable in 73% of patients. Most of the patients
had achieved 80% of their grip strength. The mean DASH score of 12.3 was comparable with other studies. Grip
strength, radial inclination and volar tilt had a significant correlation with the DASH score. Conclusion: Volar
locking plates can be used to achieve optimal reduction in all three parameters in the treatment of AO type C
fractures of the distal radius. Versatile fracture fragment reduction and angular stability enable rehabilitation
hence obtaining good functional outcomes.
