“…Other implants have also been suggested, and they include Vitallium, 21 acrylic, 22,23 and titanium, 24 which too has fallen out of favor. Some authors have also proposed a composite implant made of glutaraldehyde and bovine fibrocartilage 25 or of collagen and bone morphogenetic protein (BMP), 26 ; with unsatisfactory results.…”

Fractures of the proximal pole of the scaphoid with associated avascular necrosis and nonunion are well known to be problematic. Many techniques for fixation and reconstruction of the proximal pole of the scaphoid have been reported, often with poor results. One of the newer modalities of treatment for these difficult cases is excision of the proximal pole and replacement with a pyrocarbon implant. The ovoid shape of the implant acts as a spacer and repositions itself throughout the range of motion of the wrist. The procedure can be performed arthroscopically, thus reducing the morbidity and allowing the procedure to be a day case. Satisfactory results have been reported in elderly patients, but there is a paucity of literature regarding the outcomes in younger patients. This multicenter retrospective study evaluates the clinical, radiologic, and functional outcomes in patients under the age of 65 years with a minimum follow up of 5 years. There were 14 patients with scaphoid nonunion advanced collapse (SNAC) grade I, II, or III wrists, with a mean age of 53 years and mean follow up of 8.7 years. There were improvements in all of the patient related variables including VAS pain scores (7.5 to 0.7), extension (45°to 60°), flexion (32°to 53°), and grip strength (15.8 to 34.6 kg). Complications included volar subluxation of the implant, which was acutely surgically corrected (1), volar subluxation of the implant, with persistent pain that required a four-corner fusion (2), and secondary radial styloidectomy (3). This technique is an attractive, minimally invasive alternative for nonunion and avascular necrosis resulting from fractures of the proximal pole of the scaphoid. The authors provide details of the technique, including technical suggestions for performing the procedure.

“…Similar treatment has been advocated for musculoskeletal connective tissues (Ersek and Delerm, 1988; Gibeault et al, 1989; Heatley and Allen, 1986; Kangesu et al, 1991), most notably for the knee meniscus (Canham and Stanish, 1986; Heatley and Revell, 1985; Heatley and Revell, 1986; Hunter et al, 2003; Hunter et al, 2005; Hunter et al, 2010; Powers et al, 1988; Revell and Heatley, 1988; Wisnewski et al, 1988). These studies have similarly demonstrated that glutaraldehyde treatment may alter mechanical properties (Hunter et al, 2003; Wisnewski et al, 1988), though proper titration of the concentration may control this variation (Hunter et al, 2003; Hunter et al, 2005).…”

This study examined functional properties and biocompatibility of glutaraldehyde-fixed bovine articular cartilage over several weeks of incubation at body temperature to investigate its potential use as a resurfacing material in joint arthroplasty. In the first experiment, treated cartilage disks were fixed using 0.02, 0.20 and 0.60 percent glutaraldehyde for 24 h then incubated, along with an untreated control group, in saline for up to 28 days at 37 °C. Both the equilibrium compressive and tensile moduli increased nearly twofold in treated samples compared to day 0 control, and remained at that level from day 1 to 28; the equilibrium friction coefficient against glass rose nearly twofold immediately after fixation (day 1) but returned to control values after day 7. Live explants co-cultured with fixed explants showed no quantitative difference in cell viability over 28 days. In general, no significant differences were observed between 0.20 and 0.60 percent groups, so 0.20 percent was deemed sufficient for complete fixation. In the second experiment, cartilage-on-cartilage frictional measurements were performed under a migrating contact configuration. In the treated group, one explant was fixed using 0.20 percent glutaraldehyde while the apposing explant was left untreated; in the control group both explants were left untreated. From day 1 to 28, the treated group exhibited either no significant difference or slightly lower friction coefficient than the untreated group. These results suggest that a properly titrated glutaraldehyde treatment can reproduce the desired functional properties of native articular cartilage and maintain these properties for at least 28 days at body temperature.
