Glenn Boehnlein
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 11.5% in the quarter compared to 9.2% in the third quarter of 2023. This quarter had one more selling day than 2023. We had a 1.2% favorable impact from pricing. We continue to see a positive trend in our pricing initiatives, both in the US and international markets and both with our MedSurg and Neurotech and Orthopedic and Spine segments, each contributing positive pricing for the quarter.
Foreign currency had a 0.1% unfavorable impact on sales. In the US, organic sales growth was 11.4%. International organic sales growth was 11.7%, driven by positive sales momentum across our international markets. Our adjusted EPS of $2.87 in the quarter was up 16.7% from 2023, driven by strong sales growth and continued margin expansion. Foreign currency exchange translation had minimal impact on our adjusted EPS for the quarter.
Now, I will provide some highlights around our quarterly segment performance. In the quarter, MedSurg and Neurotechnology had constant-currency sales growth of 12.9% and organic sales growth of 12.7%, which included 13.2% of US organic growth and 11.2% of international organic growth. Instruments had US organic sales growth of 9.9%, led by strong double-digit growth in the Surgical Technologies business. From a product perspective, sales growth was led by waste management, smoke evacuation, tourniquet cuffs, Steri-Shield and power tools.
Endoscopy had US organic sales growth of 10.9% with strong growth across all businesses. Growth in the quarter was fueled by robust demand for our OR infrastructure and renovations and the continued success of the 1788 Platform and sports medicine shoulder products. Medical had US organic sales growth of 18.5%, driven by strong performances across all of its businesses, Acute Care, Sage and Emergency Care. From a product perspective, the Medical business was led by strong sales growth in beds and stretchers, Sage products, transport capital and defibrillators. The order pipeline for LIFEPAK 35 is robust and continues to drive excitement in the market.
Neurovascular had US organic sales growth of 1.5%, which reflects solid performance in our core hemorrhagic products, offset by recovering performance in our flow diverting stent products due to supply chain issues earlier in the year and competitive pressures in our ischemic business. And finally, Neuro Cranial had US organic sales growth of 16.1%, led by strong growth in our bone mill, high-speed drills, bipolar forceps and craniomaxillofacial products.
Internationally, MedSurg and Neurotechnology had organic sales growth of 11.2%, led by double-digit organic growth in our Endoscopy and Medical businesses. Geographically, this included strong performances in Canada, the United Kingdom, Australia, New Zealand, Japan and most of our emerging markets. Orthopedics and Spine had constant-currency sales growth of 10.8% and organic sales growth of 9.7%, which included organic growth of 8.6% in the US and 12.3% internationally.
Our US Knee business grew 8.4% organically, reflecting our market-leading position in robotic-assisted knee procedures and the continued strength of our installed Mako base as well as continued momentum in new Mako installations. Our US Hip business grew 10.9% organically, driven by the continued success of our Insignia Hip Stem and momentum from our Mako Robotic Hip platform.
Our US Trauma and Extremities businesses, business grew 11.8% organically with double-digit sales growth across our core trauma, upper extremities and biologics businesses. Our US Spine business grew 2.4% organically, led by performance in our interventional spine business. Our US Other Ortho business had a slight decline organically of 0.6%, driven by seasonal Mako deal mix and a decline in bone cement. Internationally, Orthopedics and Spine grew 12.3% organically, including strong performances in South Korea, Japan, Canada, Europe and most of our emerging markets.
Now I will focus on operating highlights in the second quarter. Our adjusted gross margin of 64.5% was 20 basis points unfavorable from third quarter of 2023. This variance resulted primarily from mix. Adjusted R&D spending was 6.6% of sales, which was 20 basis points lower than the third quarter of 2023. Our adjusted SG&A was 33.2% of sales, which was 130 basis points lower than the third quarter of 2023, due to natural expense leverage combined with spending discipline, somewhat offset by investments to support growth.
In summary, for the quarter, our adjusted operating margin was 24.7% of sales, which was 130 basis points favorable to third quarter of 2023. Net adjusted other income and expense of $42 million for the quarter was $19 million lower than 2023, driven by favorable interest income on our invested cash balances. We expect our full-year net adjusted income and expense to be in the range of $230 million to $240 million. The third quarter of 2024 had an adjusted effective tax rate of 15.8%, reflecting the impact of geographic mix and certain discrete tax items. We now expect our full-year adjusted effective tax rate to be at the high-end of our previously communicated range of 14% to 15%.
Focusing on the balance sheet, we ended the third quarter with approximately $4.7 billion of cash, marketable securities and short-term investments. Total debt was approximately $15.5 billion. This debt includes approximately $3 billion from our bond offerings in September 2024, a portion of which will be used to pay down upcoming debt maturities in the fourth quarter.
Turning to cash flow, our year-to-date cash from operations is $2.3 billion, an increase of $120 million from 2023, driven mainly by higher earnings and improvements in inventory and accounts payable, partially offset by higher accounts receivable from sales timing and other expense timing.
Based on our year-to-date performance, sustained demand for our capital products and healthy procedural volumes, we now expect full-year 2024 organic sales growth to be in the range of 9.5% to 10%. This includes a favorable pricing impact of 0.5% to 1%. If foreign exchange rates hold near current levels, we anticipate full-year sales will be slightly unfavorably impacted and adjusted EPS will be negatively impacted by approximately $0.10, both of which are reflected in our guidance.
With a strong first nine months of the year, strong Q4 sales and operating margin momentum, we now expect adjusted net earnings per diluted share to be in the range of $12 to $12.10.
And now I will open up the call for Q&A.
