“…16 DCS is easier to insert (over a previously positioned guide pin) and requires only 2-plane alignment. 1,20,25 It facilitates implant rotation after sliding under the vastus lateralis during indirect reduction and enables sagittal alignment by rotation of the plate-DCS construct. 16 The DCS is placed more proximally in the greater trochanter.…”

Purpose. To review the results of indirect reduction and mini-incision dynamic condylar screw (DCS) fixation for comminuted subtrochanteric femoral fractures. Methods. 29 men and 14 women aged 25 to 65 (mean, 44) years with comminuted subtrochanteric femoral fractures underwent indirect reduction and mini-incision DCS fixation. Fractures were classified according to the AO classification (10 type 32B and 33 type 32C) and Seinsheimer classification (6 type III, 15 type IV, and 22 type V). Functional outcomes were assessed using the Harris hip score and Merle d'Aubigne score. Results. The mean time to full weight bearing was 11 (range, 8-19) weeks. The mean time to union was 16 (range, 13-22) weeks. There were no cases of non-union or implant failure after a mean follow-up period of 25 (range, 18-30) months. Seven patients had a mean limb length discrepancy of 1.5 (range, 1-2) cm. Two patients had coxa vara and persistent limp. Conclusion.Results of indirect reduction and miniincision DCS fixation for comminuted subtrochanteric femoral fractures are favourable. Proper planning and execution of the technique is required to achieve good functional outcomes and avoid complications. Preservation of vascularity of the medial fragments leads to rapid callus formation and early union and hence avoids implant failure and secondary bone grafting.

“…In our series we had no complications using DHS in 25 patients, with 88% excellent and good result in this group. In 1992, Radford and Howell [28] reported 64% good results with DCS. We were more successful in using DCS, with 82% excellent and good results, and in spite of the previous reports that DCS implant is stronger biomechanically than DHS, because it allows additional screw fixation to the proximal fragment [35].…”

Results of Subtrochanteric Fractures Treated with Dynamic Hip Screw and Dynamic Condylar Screw

1998

Objective: To study the results of 48 patients with subtrochanteric fractures of the femur, treated surgically with fixation by dynamic hip screw (DHS) in 25 patients (52%), and by dynamic condylar screw (DCS) in 23 patients (48%), at Al-Razi Orthopaedic Hospital in the period between January 1990 and June 1995. Methods: The patients were reviewed with the mean follow-up of 16 months (range 6–30 months). Results: The mean duration of union was 4 months in 46 patients (95.8%). Non-union was evident in 2 patients (4.2%). Two patients (4.2%) developed delayed union, which was successfully united after re-operation by autogenous bone graft. One patient (2.1%) had wound infection. Metal failure occurred in the 2 non-union patients (4.2%). Excellent and good clinical and radiological scoring was achieved in 41 patients (85.4%), fair in 5 (10.4%), and failure in 2 patients (4.2%). Conclusions: We concluded that DHS and DCS are among the best fixation devices in the armamentarium for subtrochanteric fracture management. Although all the complications in our series occurred in the DCS group, with better clinical and radiological scoring in the DHS group, we could not conclude that DHS is better than DCS because more complex and unstable subtrochanteric fracture types were treated by DCS (8 patients with type B and 8 patients with type C, 69.6%), comparable to 19 patients with type A (76%) and only 6 patients (24%) in type B in the DHS group. The small number of patients in each group makes also the difference between them statistically insignificant.

“…Over the past years, the implants and techniques have improved. It is now recognized by most orthopaedic surgeons the distal femoral fractures are best treated by open reduction and internal fixation [11][12][13][14][15][16][17][18][19][20][21][22][23][24]. The goals in the treatment are the restoration of bone length, anatomic articular surface alignment and rotation, early mobilization of the associated joints rapid fracture union and minimal complications [25][26][27][28].…”
