“…The high cobalt levels generated through the alumina abrasive condition is unlikely to be encountered clinically, although instances of ceramic head fracture in vivo have been reported leading to substantial damage of the polyethylene liner. 30 – 33 The damage generated in the heads produced a comparable surface roughness to that observed and commonly reported in retrieved components. 12 …”

Hypersensitivity reactions in patients receiving metal-on-metal hip replacements have been attributed to corrosion products as observed by elevated cobalt and chromium ions in the blood. Although the majority of cases are reported in metal-on-metal, incidences of these reactions have been reported in the metal-on-polyethylene patient population. To date, no in vitro study has considered cobalt release for this bearing combination. This study considered four 28 mm and seven 52 mm diameter metal-on-polyethylene bearings tested following ISO standard hip simulator conditions as well as under established abrasive conditions. These tests showed measurable cobalt in all bearings under standard conditions. Cobalt release, as well as polyethylene wear, increased with diameter, increasing from 52 to 255 ppb. The introduction of bone cement particles into the articulation doubled polyethylene wear and cobalt release while alumina particles produced significant damage on the heads demonstrated by cobalt levels of 70,700 ppb and an increased polyethylene wear from a mean value of 9–160 mm3/mc. Cobalt release was indicative of head damage and correlated with polyethylene wear at the next gravimetric interval. The removal of third body particles resulted in continued elevated cobalt levels in the 52 mm diameter bearings tested with alumina compared to standard conditions but the bearings tested with bone cement particles returned to standard levels. The polyethylene wear in the bone cement tested bearings also recovered to standard levels, although the alumina tested bearings continued to wear at a higher rate of 475 mm3/mc. Cobalt release was shown to occur in metal-on-polyethylene bearings indicating damage to the metal head resulting in increased polyethylene wear. While large diameter metal-on-polyethylene bearings may provide an increased range of motion and a reduced dislocation risk, increased levels of cobalt are likely to be released and this needs to be fully considered before being widely adopted.

“…14 Finally, Nho et al described one zirconia-on-UHMWPE femoral head fracture. 15 Our report, to our knowledge, represents a rare case of an atraumatic femoral head fracture of the newest generation of delta ceramic in a COP-articulated THA. Historically cited fracture risk factors of trauma, small ball diameter, and short neck length are unlikely to contribute in this patient's case as his mechanism was atraumatic, he had a 32 mm head, and he had a medium 0 mm neck length.…”

Atraumatic Delta Head Fracture in a Ceramic-On-Polyethylene Total Hip Arthroplasty

A 47-year-old man underwent a left ceramic-on-polyethylene total hip arthroplasty with a delta ceramic femoral head. At 20 months postoperatively, he presented with acute left groin pain after he stepped over a fishing rod while on a boat. A fracture of the femoral head without trauma was diagnosed upon presentation. Manufacturing practices with improvements in each successive generation have decreased historically high ceramic fracture rates considerably. Although femoral head fractures have proven to be extremely rare both in ceramic-on-polyethylene articulations and with the newest delta femoral head, it is important to remain vigilant in all situations involving ceramics.

“…Ceramic implants were first used in THA by Boutin in the 1970s11). Ceramic-on-ceramic articulation has gained popularity due to its favorable properties (e.g., low wear rate, low friction coefficient)412). Ceramic materials are frequently preferred in prosthetic applications, especially in patients with long life expectancy.…”

Non-traumatic Ceramic Head Fracture in Total Hip Arthroplasty with Ceramic-on-Ceramic Articulation at Postoperative 16th Years

Ceramic articulation has gained popularity in total hip arthroplasty (THA); however, one of the most important concerns about the use of ceramic materials is the potential for breakage. Importantly, almost all ceramic fractures occur within the first six years after surgery. Here, we present a case report of a 52-year-old female patient who experienced an atraumatic ceramic head fracture at the 16th year after surgery. Key parameters that may be associated with ceramic head fracture are considered to be the use of a 28-mm head and high body mass index (BMI); the patient described here had a BMI of 34.3 kg/m 2 . Surgical treatment of the case included removal of the broken ceramic head and replacement with an alumina matrix composite ceramic head. At the 12th month follow-up visit, the patient was mobilized independently and could perform her daily activities. Ceramic head fracture after THA may occur even in late periods after surgery. For the treatment of fractures of ceramic material, the fractured component must be removed together with extensive soft tissue excision to ensure that no residual fragments are left behind.
