Background. Intertrochanteric fractures of the proximal femur are one of the most common fractures encountered, and dynamic hip screw with a side plate is the standard treatment. We compared a minimally invasive surgical technique with the conventional surgical technique used in the fixation of intertrochanteric fractures with the dynamic hip screw (DHS) device. Methods. Thirty patients with such fractures were treated with the conventional open technique and 30 with a new minimally invasive technique. Patients in both groups were followed up for 1 year. Results. There was less blood loss, minimal soft tissue destruction, shorter hospital stay, and early mobilization with the minimally invasive technique. Conclusion. The present study finds minimally invasive technique superior to conventional (open) DHS.

Distal Tibial Fractures

Distal tibial fractures are now commonly treated via intermedullary plate fixation due to higher rates of union and lower rates of postoperative complications. However, patient specific bone morphology demands manual deformation of the plate to ensure appropriate fit along the bone contours, and depending on the material of the plate, different outcomes have been reported along with postoperative complications. A comparative analysis of Stainless Steel 316L and Ti-6Al-4V alloys was carried to estimate the safe bending limit for appropriate fits. The results from the ANSYS FEA simulations were validated with experiments based on ASTM F382-99. It is found that SS316L is better suited for large deformations (up to 16˚ in proximal tip and 7.5˚ in distal end) and Ti for smaller deformation contours (up to 3˚ in proximal tip and 1.8˚ in distal end). The results of this study have profound implications for the choice of plates based on preliminary radiographical fracture examinations to ensure better fixation and higher rates of union of distal tibial fractures.

Purpose: Although plate osteosynthesis is commonly used to treat proximal ulna fracture, its treatment method is controversial because of complications such as large incision, long operation time, and soft tissue injury. Therefore, intramedullary headless compression screw (HCS) and Steinmann pin are considered as alternative treatment options. In this study, we aim to compare bending strength of plate and cortical screws, HCS, and Steinmann pin for proximal ulnar shaft fracture with sawbone. Methods: Transverse type fractures were made intentionally at the distal 7 cm from the proximal end of ulna sawbones and fixated with plate, HCS, and Steinmann pin after reduction. Three-point bending tests were performed with total of 21 sawbones, seven pieces for each group. Results: Average ultimate bending strength for each group was as follows; 521.7N for plate fixation group, 706.4N for HCS fixation group, and 812.6N for Steinmann pin fixation group. Statistically significant results were observed among the three groups (p<0.01). When two groups were compared separately, Steinmann pin fixation and plate fixation (p<0.01), Steinmann pin and HCS fixation (p=0.047) showed statistical significance. There was a significant trend between HCS and plate fixation group (p=0.064).Conclusion: HCS and Steinmann pin fixation showed higher bending strength when compared to plate fixation for proximal ulnar shaft fracture in sawbone. Although further studies are needed, HCS and Steinmann pin fixation are promising fixation methods that may be used as an alternative to plate fixation.

Category: Ankle Introduction/Purpose: For patients suffering from severe ankle and hindfoot arthritis or deformity, tibiotalocalcaneal (TTC) or pantalar arthrodesis may be the best option to achieve a plantigrade and painless foot. These fusions are typically fixed with a retrograde intramedullary nail, a lateral side plate, or screws alone. Theoretically, the advantages of a lateral side plate applied via a trans-fibular approach include the use and the multiple points of fixation available in the tibia, talus, and calcaneus. The results of a novel side plate construct with a unique screw hole that extends underneath the calcaneus are presented in this study. A large diameter screw can be inserted retrograde through this inferior hole to engage the medial tibial cortex and provide axial compression across the ankle and subtalar joints. Methods: This study retrospectively evaluated 39 patients that underwent a tibiotalocalcaneal (TTC) or pantalar arthrodesis using this novel lateral plate fixation technique by one of three fellowship trained surgeons at a tertiary referral center. Patients with less than a one year follow up were excluded. Thirty-nine patients were identified between 2012 and 2016. Two patients were deceased from other causes, 2 had a below the knee amputation due to chronic pain, and 9 were lost to follow up. Pre- and postoperative General Health and Wellness (SF-12) and Revised Foot Function Index scores were obtained. Study subjects were seen for a clinical evaluation and final post-operative x-rays. The Shapiro-Wilk test was used to test for normality. The paired student’s t-test was used to compare pre- and post-surgical outcome measures. Results: Twenty-six patients were included in the study group. Mean follow up time was 34.42 ± 12.94 months. The SF-12 score was 32.2 ± 10.22 (physical) and 54.8 ± 10.7 (mental) before surgery, and 41.35 ± 9.21 (p < 0.01) and 56.5 ± 7.47 (p = 0.73) at final follow-up, respectively. The FFI score was 106 ± 32.69 before surgery and 53.94 ± 24.14 after surgery (p = 0.06). Eighteen patients were satisfied or very satisfied with the outcome of the surgery (70%). CT confirmation of joint fusion was obtained in all 26 patients. Twenty out of the 26 patients demonstrated fusion of all joints (77%). There were 2 ankle, 1 subtalar, and 1 talonavicular nonunions. In total, 44 of 48 total joints were fused (91%). Conclusion: Tibiotalocalcanceal and pantalar arthrodesis using a novel lateral plate for the treatment of complex deformity and severe osteoarthritis demonstrated acceptable fusion rates considering the number of patients with high risk factors for nonunion in this study group. Complications included fractures at the proximal end of the plate construct and persistent neurapraxia which was well tolerated. Patients reported significant improvements in SF-12 clinical scores at final 34 month follow-up.

SummaryTo compare the biomechanical properties of a hybrid locking compression plate (LCP) construct with the compression screw technique as a treatment for transverse mid-body proximal sesamoid bone fractures.Ten paired forelimbs from abattoir horses were used. The medial proximal sesamoid bone of each limb was osteotomized transversely and randomly assigned, to either repair with a two-hole 3.5 mm LCP or a 4.5 mm cortical screw placed in lag fashion. Each limb was tested biomechanically by axial loading in single cycle until failure. The point of failure was evaluated from the loaddisplacement curves. Then a gross evaluation and radiographs were performed to identify the mode of failure.The loads to failure of limbs repaired with the hybrid LCP construct (4968 N ± 2167) and the limbs repaired with the screw technique (3009 N ± 1091) were significantly different (p <0.01). The most common mode of failure was through a comminuted fracture of the apical fragment of the proximal sesamoid bone.The LCP technique has potential to achieve a better fracture stability and healing when applied to mid-body fractures of the proximal sesamoid bone. Further testing, particularly fatigue resistance is required to corroborate its potential as a treatment option for mid-body fractures of the proximal sesamoid bone.
