Electrosurgical devices are routinely employed during surgery. The use of a Bovie Electrosurgical Unit (ESU) to facilitate the passage of a suture needle through bone has not been studied in the literature. This study aimed to identify force reduction with the application of Bovie ESU to the suture needle through the bone. Peak and the average axial force required for a suture needle to penetrate cadaveric proximal humeri were measured using a custom setup. Twenty-four trials were conducted without electricity, and 72 trials were conducted with a Bovie ESU applying current. Needle size and Bovie ESU power settings were varied. t Tests and analysis of variance were used with p ≤ 0.05 denoting statistical significance. The application of electricity reduced the peak and average axial force needed for a needle to pierce bone, regardless of the Bovie ESU power setting (p < 0.001). The average peak force with the Bovie ESU was 65.7 N, compared with 126.0 N without (p < 0.001), a 47.9% reduction. The average axial force with the Bovie ESU was 38.2 N compared with 81.8 N without (p < 0.001), a 53.3% reduction. There was no significant difference in peak or average axial forces between power settings. At 30 and 90 W of power, larger needle size was associated with significantly lower peak (p = 0.001 and p < 0.001, respectively) and axial (p = 0.002 and p = 0.004, respectively) force. The Bovie ESU reduces the axial force required to pass a suture needle through bone. The use of this technique may allow for the avoidance of drilling for soft tissue repair.*A resident brought this technique back with him to our institution.
Surgical repair of the Achilles tendon is a common procedure in cases of acute rupture. Open Achilles tendon surgery with a traditional extensile approach is most often performed in the prone position, but this can lead to numerous complications. The mini-open approach for repair in the supine position may avoid the risks of the prone position. The purpose of this study is to compare perioperative outcomes and differences in cost between patients undergoing acute Achilles rupture repair with mini-open approach, incision of approximately 3 cm, in the supine position versus traditional approach in the prone position. MethodsPatients who underwent surgical repair of acute Achilles rupture at a single institution were retrospectively identified using Current Procedural Terminology (CPT) code 27650. Complication rates and the total cost charged to the insurance companies of both the supine and prone groups were calculated. ResultsA total of 80 patients were included for analysis, 26 supine and 54 prone. The difference in average total time in the operating room was statistically significant. The prone position took approximately 15% more time (118.7 minutes) compared to the supine position (100 minutes) (p = 0.001). While not statistically significant, the total cost for the supine group ($19,889) was less than the for the prone group ($21,722) (p = 0.153) Average postoperative pain score, infection rate, dehiscence rate, sepsis rate, and deep vein thrombosis (DVT) rate were also similar between the two groups. No patient in either group experienced rerupture of the Achilles tendon within the first year of primary repair. ConclusionThe mini-open approach in the supine position may be advantageous in the repair of acute Achilles rupture in that it reduces total time in the operating room and total cost while maintaining positive patient outcomes. Prospective clinical studies are warranted to validate these assessments.
Background: No study has examined the incidence of risk factors for postoperative falls following foot and ankle surgery. We investigated the incidence and risk factors for postoperative falls in foot and ankle surgery using inpatient and outpatient population. Methods: A single fellowship-trained foot and ankle surgeon instituted collection of a postoperative fall questionnaire at 2 and 6 weeks postoperatively. A retrospective review of 135 patients with complete prospectively collected fall questionnaire data was performed. Patient demographic information, injury characteristics, comorbidities, baseline medications, length of hospital stay, visual analog scale (VAS) pain scores were collected. After univariable analysis, a multivariable binary logistic regression was conducted to assess independent risk factors for postoperative falls. Results: The median (interquartile range) age was 52 (21) and body mass index was 32.7 (11.1). A total of 108 patients (80%) underwent outpatient procedures. Thirty-nine of the 135 patients (28.9%) reported experiencing a fall in the first 6 weeks after surgery. In multivariable analysis, antidepressant use (adjusted odds ratio 3.41, 95% CI 1.19-9.81) and higher VAS pain scores at 2 weeks postoperatively (adjusted odds ratio 1.27, 95% CI 1.08-1.50) were found to be independent risk factors for postoperative falls. Conclusion: This study found a high incidence of postoperative falls in the first 6 weeks after foot and ankle surgery. Baseline antidepressant use and higher 2-week VAS pain scores were associated with postoperative falls. Foot and ankle surgeons should discuss the risk of falling with patients especially those with risk factors. Level of Evidence: Level III, retrospective cohort study at a single institution.
Introduction. The open, lateral sinus tarsi approach is the most commonly used technique for subtalar arthrodesis. In this cadaver study, we measured the maximum joint surface area that could be denuded of cartilage and subchondral bone through this approach. Methods. Nine fresh frozen above-knee specimens were used. The subtalar joint was accessed through a lateral incision from the fibular malleolus distally over the sinus tarsi area to the level of the calcaneocuboid joint. Cartilage was removed from the anterior, middle, and posterior facets of the calcaneus and talus using an osteotome and/or curette. ImageJ was used to calculate the surface areas of undenuded cartilage. Results. No specimens were 100% denuded of cartilage on all 6 measured surfaces. The greatest percentages of unprepared surface area remained on the middle facet of the talus (18.66%) and the middle facet of the calcaneus (14.51%). The anterior facet of the talus was 100% denuded in 6 specimens, while the middle and posterior facets were 100% denuded in 3 specimens. The anterior facet of the calcaneus was also 100% denuded in 6 specimens, while the middle and posterior facets were 100% denuded in 3 and 4 specimens, respectively. The average total unprepared surface area per specimen was 8.67%. Conclusion. The lateral sinus tarsi approach provides adequate denudation of cartilage of the subtalar joint in most cases. Total percentage of unprepared joint surface may range from approximately 2% to 18%. Future clinical studies are warranted to assess whether this technique results in optimal union rates.
