Return-to-work following shoulder arthroplasty in adults with osteoarthritis.

BACKGROUND: Anatomic total shoulder arthroplasty (aTSA) and hemiarthroplasty (HA) have demonstrated significant improvement in shoulder function and pain relief. Work-related outcomes have become increasingly important, while the current literature lacks evidence related to return-to-work (RTW) and which factors might have an influence on it. AIMS: This study aimed to assess RTW in patients who have received aTSA or HA at a minimum of 1-year follow-up after surgery, and secondary to evaluate possible prognostic factors associated with RTW. METHODS: We performed a retrospective query in employed patients diagnosed with primary osteoarthritis of the shoulder, who received either an aTSA or HA between February 2006 and February 2021. Preoperative and post-operative work and sports participation were assessed. RESULTS: Forty-four patients participated in this study (98% compliance), of which 40 patients (91%) were able to RTW at a median time of two (interquartile range: 2-4) months post-operatively. Patients with a medium-/high-demand occupation demonstrated RTW at a significantly lower rate (79%) than those with light-demand occupations (100%; P = 0.03). There was a statistically significant association between return to full employment and patients' expectation to fully return, absence of preoperative work adjustments and preoperative sick leave (odds ratio: 16.9 [3.1-93.5]; 18.3 [2.1-160.4]; 0.1 [0.0-0.6]). CONCLUSIONS: aTSA and HA facilitate excellent RTW rates. Patients with a medium-/high-demand occupation return at a significantly lower rate. The ability to RTW seems to be multifactorial and the results found might not be attributed to shoulder arthroplasty alone.

Less Pain, but no changes in maximal inclination angles during an overhead reach task following local anesthetic in patients with ongoing shoulder pain.

This multicenter observational study aimed to assess how pain reduction, induced by local anesthesia, affects the relative angular contributions of the shoulder girdle and trunk to the maximal angular performance during a semi-constrained overhead reach task in patients with ongoing shoulder pain. Twenty-nine individuals (age 59.0 SD 12.8 years;16-male) with symptomatic shoulders were administered corticosteroid and lidocaine injections by their attending orthopedic surgeon. Immediately before and after the injections, participants reached for a target on the ceiling ten times as high as possible while their pain levels, shoulder, and trunk movements were recorded. The analysis revealed that there was a significant reduction in pain following the injections. However, there were no significant differences in maximum shoulder and trunk inclination angles between the pre- and post-injection conditions. Notably, there were slight but statistically significant alterations in humeroscapular kinematics during the initial phase of arm elevation following the injections. In conclusion, acute pain relief following local anesthetics is not associated with immediate alterations in maximum shoulder girdle and trunk inclination angles during a semi-constrained overhead reach task in patients with ongoing shoulder pain. However, there are signs of small alterations in humeroscapular kinematics during the initial phase of arm elevation.

Closed reduction intermetacarpal Kirschner wire fixation in the treatment of unstable fractures of the base of the first metacarpal.

The purpose of this study was to describe the results of extra-articular and intra-articular fractures, at the base of the first metacarpal, treated with closed reduction and percutaneous fixation with intermetacarpal Kirschner wires. Outcome was evaluated by experienced pain, functional outcome and radiographic indications for arthritis. In total, 25 patients with unstable fractures at the base of the first metacarpal underwent closed reduction and percutaneous fixation of the fracture. Prospectively collected data of 25 consecutive patients were evaluated retrospectively, assessing stability of fixation, operation time and the occurrence of fracture dislocation during and after treatment. All patients were assessed at 1, 3, 6 and 24 months. Follow-up included questionnaires: functional tests including grip and pinch measurement and radiographic analysis for post-traumatic arthritis, using the modified Eaton-Littler classification. In total, 15 patients with extra-articular fractures and 10 patients with intra-articular fractures were treated with this technique. In the group of extra-articular fractures of 15 patients, only one patient had loss of grip strength greater than 20% in comparison with the contra-lateral side (corrected for hand dominance). No clinically important difference was found for pinch strength. One patient experienced functional limitations and was unable to return to a previous hobby. In the patients group with intra-articular fractures, seven patients had a Bennett fracture and three a Rolando fracture. One patient with a Bennett fracture had a loss of pinch strength greater than 20% corrected for hand dominance. One of the three patients with a Rolando fracture had grip loss greater than 20%. None of the patients with intra-articular fractures experienced any functional limitations. The described fixation procedure results in a stable fixation of the fracture fragments, and no secondary dislocation of the fracture occurred. Fractures consolidated within 32 (26-50) days and no new fractures were observed. These results suggest that this technique can be safely used in the treatment of extra-articular fractures as well as intra-articular fractures at the base of the first metacarpal.
