Cementless stems are porous or coated implants used in total hip replacement. Through biologic fixation the bone tissues grows into the pores of the implant and secure it firmly. Cementless stems help reduce two major complications of hip replacement, namely, chances of infection and loosening of the prosthesis. The pores are designed to preserve the natural nutrition of femoral bone and facilitate rehabilitation by allowing for unrestricted blood flow. This helps develop a strong connection between the bone and implant, which reduces the friction in the intramedullary cavity and reduces the pain occurs in the hip post implantation.
There are different types of cementless neck stems available in market such as grit blasted, porous-coated, HA-coated and porous plus HA. These provide different features such as porous-coated design of cementless neck stems promotes bone ingrowth and 3-dimensional interlocking between the bone and implant, the HA-coated stems provide high strength and hydroxyapatite coating helps to secure fixation. The cementless neck stems provide increased motion of the stem within the artificial humeral head and artificial glenoid cavity.
A total hip replacement surgery is carried out in case of hip joint damage, rheumatoid arthritis, osteonecrosis, fracture and bone tumors, which may lead to hip breakdown and create need of hip replacement surgery.
According to the Centers for Disease Control and Prevention (CDC), in U.S. each year around 332,000 total hip replacements are performed. The percentage of cementless procedures is high among all procedures and it is expected that this will grow year-on-year which in turn the growth of cementless neck stems market around the globe.
Furthermore, NJR stats says that, out of all hip replacement procedures the percentage of cementless hip replacement varies according to age group and gender such as, in men cementless hip replacement is 50.8% in less than 55 year old, 51.6% in 55-64 year old, 42.2% in 65-74 year old and 28.8% in more than 75 year old. Also, in case of women it is 57.1% in less than 55 years old, 51% in 55-64 years old, 36.1% in 65-74 years old and 22.4% in more than 75 year old.

Rising prevalence of osteoarthritis and increase in hip replacement rate expected to fuel the growth of cementless neck stems market in the near future:
The prevalence of osteoarthritis is increasing due to increase in obese and aging population. As per United Nations, people over 60 years of age will account for over 20% of the world’s population by 2050. Of this, around 15% (130 million people) are projected to suffer from symptomatic osteoarthritis.
According to Organisation for Economic Cooperation and Development (OECD), in OECD countries, the rate of hip replacement is raised by 35% in between 2000 and 2013, furthermore, the highest hip replacement is observed in Switzerland, Germany and Austria in 2013.
Rise in number of hip replacement globally is expected to favor growth of the cementless neck stems market in the near future.
Developed regions major growth engines of the cementless neck stems market
The increasing hospitalization rate due to osteoarthritis and high awareness about available treatment in developed regions will drive the market in near the future. For instance, as per Australian Society of Orthopaedic Surgeons in Australia hospitalization rate with osteoarthritis increased to 415 in 2013-2014 from 362 in 2004-2005 per 100,000 population. Furthermore, in during 2003-2014, the revision hip replacement rate in private sector increased by 19.2% and in public sector by 33.8%.
North America holds major market share, followed by Europe and APAC region. APAC is projected to be the fastest growing region in the cementless neck stems industry over the forecast period. This is mainly attributed to the large population of people aged 20-65 in the region. Also, this growth is supported by developing healthcare infrastructure and increasing availability of healthcare facilities to perform the implantation.
Key players operating in the cementless neck stems market include Limacorporate S.p.a., DePuy Synthes, Smith & Nephew, Waldemar LINK GmbH & Co. KG, Altimed JSC, B. Braun Melsungen AG, DJO Global, Inc., Biotechni S.A.S, Imeco S.A. and Stryker.
