Treatment of reverse oblique trochanteric femoral fractures is still challenging. We present the results of our proximal nailing surgery performed for reverse obliquity intertrochanteric fractures using two lag screws and evaluated the quality of the reduction, operative time, complications and functional status of the patients. Fifteen patients with AO/OTA 31 A-A3 fractures were treated by proximal femoral nailing in our trauma centre. The mean Harris hip score was 74.66 (range 65-96) and the mean Barthel activity score was 15.71 (range 12-20). The mean duration of surgery was 48 minutes and the average consolidation time was 8.6 weeks. No intraoperative complications or postoperative technical failures and no stress shielding as evidenced by the lack of cortical hypertrophy at the level of the tip of the implant were detected. Intramedullary nailing with proximal femoral nails may be a good option in the treatment of reverse obliquity intertrochanteric fractures.

In radius neck fractures, reduction manipulations applied on the radial head with percutaneous K-wires may lead to epiphysis or physis damage. In this study, 16 cases were evaluated without using any percutaneous manipulations upon the displaced radius head. Rather, an Ender-pin-like, curve-tipped K-wire was inserted intramedullary (Metaizeau technique) after a certain amount of reduction by manual manipulation under fluoroscopic guidance. Complete reduction was obtained with wire rotations in 16 patients. A total of 16 patients with open growth plates with an average age of 8 years were enrolled within the scope of the study. Thirteen patients (81.25%) showed excellent clinical results, two patients (12.5%) showed good results, and one patient (6.25%) showed average results. None of the cases exhibited poor results. A single K-wire was used in nine cases, whereas two K-wires were used for fixation rigidity in seven cases with larger medullas. No sign of neurovascular deficit, synostosis, or infection was observed in any of the cases. In conclusion, the use of two wires in patients with larger medullas and emphasis on the importance of closed reduction, even without percutaneous K-wire manipulation, might lead to the development of a new treatment approach for pediatric patients with radial head fractures.

We investigated whether a proximal femoral nail (PFN) having two lag screws can be implanted without distal locking screws in AO/OTA 31-A1 and 31-A2 intertrochanteric femur fractures. Twenty-four patients with AO/OTA 31-A1 and 31-A2 fractures were treated with a PFN without distal interlocking by a single surgeon. The mean follow-up was 12 months (range: 7-23). Clinical and functional outcome was assessed according to the Harris hip score and Barthel's activity score. The fractures healed in all patients; the average consolidation time was 14 weeks (range: 9-28). Fourteen patients had excellent and good results, nine patients had fair results, and one patient had a poor result according to the Harris hip score; 17 patients had a high range of mobility according to the Barthel activity score. Our results suggested that the PFN can be successfully implanted without distal interlocking in 31-A1 and 31-A2 fractures.

Background:The incidence of fractures in the trochanteric area has risen with the increasing numbers of elderly people with osteoporosis. Although dynamic hip screw fixation is the gold standard for the treatment of stable intertrochanteric femur fractures, treatment of unstable intertrochanteric femur fractures still remains controversial. Intramedullary devices such as Gamma nail or proximal femoral nail and proximal anatomic femur plates are in use for the treatment of intertrochanteric femur fractures. There are still many investigations to find the optimal implant to treat these fractures with minimum complications. For this reason, we aimed to perform a biomechanical comparison of the proximal femoral nail and the locking proximal anatomic femoral plate in the treatment of unstable intertrochanteric fractures.Materials and Methods:Twenty synthetic, third generation human femur models, obtained for this purpose, were divided into two groups of 10 bones each. Femurs were provided as a standard representation of AO/Orthopedic Trauma Associationtype 31-A2 unstable fractures. Two types of implantations were inserted: the proximal femoral intramedullary nail in the first group and the locking anatomic femoral plate in the second group. Axial load was applied to the fracture models through the femoral head using a material testing machine, and the biomechanical properties of the implant types were compared.Result:Nail and plate models were locked distally at the same level. Axial steady load with a 5 mm/m velocity was applied through the mechanical axis of femur bone models. Axial loading in the proximal femoral intramedullary nail group was 1.78-fold greater compared to the plate group. All bones that had the plate applied were fractured in the portion containing the distal locking screw.Conclusion:The proximal femoral intramedullary nail provides more stability and allows for earlier weight bearing than the locking plate when used for the treatment of unstable intertrochanteric fractures of the femur. Clinicians should be cautious for early weight bearing with locking plate for unstable intertrochanteric femur fractures.
