1. Isometric shoulder strength: Normative Australian population data and associated factors.

Abstract

Background: Age and sex are known predictors of isometric shoulder strength and therefore must be accounted for when noting strength values or administering assessments such as the Constant Score. Given the popularity of the Constant Score, it is important to ensure protocols and values remain clinically relevant and are representative of the intended population. Method: Isometric shoulder strength was recorded for 511 participants without shoulder pathology using the ChatillonTM hand-held dynamometer. Data were stratified by age and sex for comparison with published normative strength series. Other demographic variables were evaluated using linear regression models. Results: Normative values for shoulder strength were generated. Age (p =.003, r 2 =.010) and sex (p <.001, r 2 =.026) were significant predictors of shoulder strength. Height (p =.03, r 2 =.010) was a significant predictor of strength in females and weight was a significant predictor of strength in males (p <.001, r 2 =.017). Hand dominance was also significant, with non-dominant shoulder strength associated with higher strength in females (p <.001, r 2 =.081) and lower strength in males (p <.001, r 2 =.154). Conclusion: This study generated normative shoulder strength values for a sample of the Australian population and provided a comparison between other normative scores. Significant demographic predictors in addition to age and sex were identified. Level of Evidence: III. [ABSTRACT FROM AUTHOR]

Abstract

Objectives/Interrogation: Pyrocarbon total arthroplasty is an established treatment option for arthritis of the proximal interphalangeal joint (PIPJ). We hypothesized that despite the varied results published in literature, pyrocarbon for total PIPJ arthroplasty can produce reliable and effective[for full text, please go to the a.m. URL], 14th Triennial Congress of the International Federation of Societies for Surgery of the Hand (IFSSH), 11th Triennial Congress of the International Federation of Societies for Hand Therapy (IFSHT), 11th Triennial Congress of the International Federation of Societies for Hand Therapy (IFSHT)

Abstract

Objectives/Interrogation: It is hypothesised that use of a woven polyurethane "artificial ligament" is suitable for reconstructing the scapholunate ligament. We have previously described the mini Lockdown, a technique for entirely transosseous passage of a tendon graft through the proximal[for full text, please go to the a.m. URL], 14th Triennial Congress of the International Federation of Societies for Surgery of the Hand (IFSSH), 11th Triennial Congress of the International Federation of Societies for Hand Therapy (IFSHT), 11th Triennial Congress of the International Federation of Societies for Hand Therapy (IFSHT)

Abstract

Objectives/Interrogation: The Pyrocardan® trapezometacarpal interposition implant is a free intra-articular spacer composed of pyrocarbon. It is a biconcave resurfacing implant that is both ligament and bone-stock sparing. A primary indication for use is early- to moderate-stage trapezometacarpal[for full text, please go to the a.m. URL], 14th Triennial Congress of the International Federation of Societies for Surgery of the Hand (IFSSH), 11th Triennial Congress of the International Federation of Societies for Hand Therapy (IFSHT), 11th Triennial Congress of the International Federation of Societies for Hand Therapy (IFSHT)

Abstract

Objective Pyrocardan trapeziometacarpal interposition implant is a free intra-articular spacer composed of pyrocarbon. This biconcave resurfacing implant, both ligament and bone-stock sparing, is indicated for use in early-to-moderate stage trapeziometacarpal osteoarthritis. It was hypothesized that the postoperative outcome measures of the Pyrocardan implant would be comparable to those seen with ligament reconstruction and tendon interposition (LRTI) surgeries and those reported by the designer of the implant, Phillipe Bellemère, but that strength would be greater than for LRTI. Methods In this prospective case series, 40 Pyrocardan implants were performed in 37 patients. Average age was 58 years (range: 46–71). Patients were assessed preoperatively, 3 months, 6 months, 1 year, 2 years, and beyond (long term) wherever possible. Results There have been no major complications or revision surgeries for the series. Average follow-up was 29 months (range: 12 months–7 years). Twenty-eight joints were assessed at over 2 years post index surgery. Outcome measure scores improved from preoperative assessment to the most recent follow-up equal or greater than 2 years. Average grip strength at 2 years was 30 kg, as compared with 19.6 kg in an age-matched cohort who underwent trapeziectomy and 25 kg in Bellemère's original series of Pyrocardan implants. Conclusions Pyrocardan interposition arthroplasty appears to be a safe, effective treatment for trapeziometacarpal arthritis. Patient-reported clinical outcomes were at least equivalent to LRTI and are comparable to Bellemère's original series. Grip and pinch strength appear to be better than LRTI. Level of Evidence This is a Level III, prospective observational cohort study.
