Vice President, Chief Financial Officer at Stryker
Thanks, Jason. Today, I will focus my comments on our third quarter financial results and the related drivers. Our detailed financial results have been provided in today's press release.
Our organic sales growth was 9.2% in the quarter. The third quarter of 2023 had one less selling day than 2022. The impact from pricing in the quarter was favorable by 0.3%. We continue to see a positive trend from our pricing initiatives, particularly in our MedSurg and Neurotech businesses, almost all of which contributed positive pricing for the quarter. Foreign currency had a 0.3% favorable impact on sales.
In the quarter, US organic sales growth was 9.3%, International organic sales growth was 8.9%, impacted by positive sales momentum across most of our international markets, particularly Australia, Europe and emerging markets.
Our adjusted EPS of $2.46 in the quarter was up 16% from 2022, driven by higher sales, operating margin expansion and a lower adjusted income tax rate, partially offset by the impact of foreign currency exchange, which was unfavorable $0.02.
Now I will provide some highlights around our quarterly segment performance. In the quarter, MedSurg and Neurotechnology had constant currency sales growth of 10.3% and organic sales growth of 10.1%, which included 10.9% of US organic growth and 7.4% of international organic growth. Instruments had US organic sales growth of 17.3% with strong double-digit growth across both the surgical technologies and orthopedic instruments businesses.
From a product perspective, sales growth was led by power tools, Steri-Shield, waste management, smoke evacuation and surge account. Endoscopy had US organic sales growth of 10.6% with strong double-digit growth in its Communications and Sustainability businesses. In September, the Endoscopy business continued its full launch of the 1788 camera system, which provided strong sales momentum at the end of the quarter.
Medical had US organic sales growth of 5.7% led by performances in its emergency care and Sage businesses and was impacted by a strong comparable -- growth comparable in 2022 of almost 14%. Medical continues to have a large backlog of capital orders and we expect a solid Q4 despite a huge Q4 comparable.
Neurovascular had US organic sales growth of 8.7%, reflecting a strong performance in our Hemorrhagic business. Neuro Cranial had US organic sales growth of 14.5%, which included double-digit growth in all three business units: Neurosurgical, CMF and ENT.
Internationally, MedSurg and Neurotechnology had organic sales growth of 7.4%, reflecting double-digit growth in our Instruments, Endoscopy and Neuro Cranial businesses. Geographically, this included strong performances in Australia, Europe and most emerging markets.
Orthopaedics and Spine had both constant currency and organic sales growth of 8%, which included organic growth of 6.9% in the US and 10.6% internationally. Our US Knee business grew 5.3% organically, which reflects our market-leading position in robotic-assisted knee procedures. Our US Hip business grew 3% organically, reflecting solid primary hip growth, fueled by our Insignia hip stem. Growth for both our Knee and Hip businesses reflects one less selling day in the quarter and a very strong comparable in 2022 of 12.4% for Hip and 14% for Knee.
Our US Trauma and Extremities business grew 11.5% organically with strong performances across all businesses led by upper extremities and foot and ankle. Our US Spine business grew 5.4%, led by the performance of our enabling technology and interventional spine businesses including the recently-launched Q Guidance navigation system.
Our US Other Ortho increased organically by 1.8% due to higher Mako placements in the quarter. Internationally, Orthopaedics and Spine grew 10.6% organically, including strong performances in Australia, Canada and most emerging markets.
Now, I will focus on operating highlights in the third quarter. Our adjusted gross margin of 64.7% was favorable approximately 210 basis points from the third quarter of 2022. This improvement was primarily driven by the easing of certain cost pressures that we experienced in 2022, decreases in spot buy purchases and the benefit of price and mix.
Adjusted R&D spending was 6.8% of sales, which represents a 30 basis point decrease from the third quarter of 2022, primarily due to a higher comparable in 2022 related to the ramping of costs for product launches.
Our adjusted SG&A was 34.5% of sales, which was 140 basis points higher than the third quarter of 2022 due to continued investments, including sales growth incentives and a more normalized cadence of travel and meetings. We expect our full-year SG&A as a percent of sales to be in line with 2019 levels, as we continue to invest for growth.
In summary, for the quarter, our adjusted operating margin was 23.4% of sales, which was approximately 110 basis points favorable for the third quarter of 2022. This performance is driven by the aforementioned easing of certain cost pressures primarily on gross margin. Adjusted other income and expense of $61 million for the quarter was slightly higher than 2022, driven by increased interest expense, partially offset by higher interest income. The third quarter of 2023 had an adjusted effective tax rate of 13.2%, reflecting the impact of geographic mix and certain discrete tax items. For 2023, we now expect the full-year effective tax rate to be approximately 14%.
Focusing on the balance sheet, we ended the third quarter with $1.9 billion of cash and marketable securities, and total debt of $12.7 billion. During the quarter, we paid down $100 million of debt.
Turning to cash flow. Our year-to-date cash from operations is $2.2 billion. This performance reflects the results of net earnings and higher accounts receivable collections.
Considering our year-to-date results, our robust backlog for capital equipment and continued positive procedural trends, we now expect full-year 2023 organic sales growth to be in the range of 10% to 10.5%. We expect pricing to be slightly positive for the full-year. If foreign currency exchange rates hold near current levels, we anticipate sales will be unfavorably impacted by approximately 0.6% and adjusted EPS will be unfavorably impacted from $0.10 to $0.15 per share for the full-year, both of which are included in our guidance. Based on our performance in the first nine months of the year, together with our strong sales momentum, we now expect adjusted earnings per share to be in the range of $10.35 to $10.45 per share.
And now, I will open up the call for Q&A.
