Although intramedullary (IM) Kirschner wire (K-wire) fixation allows early motion, many surgeons continue to apply postoperative splinting due to concerns about stability. We aim to determine if a single IM K-wire fixation without immobilisation yields better outcomes and faster recovery of hand function. <b>Methods:</b> A single-centre, prospective and randomised controlled trial was conducted between November 2024 and November 2025 involving isolated transverse fractures of the second to fifth metacarpal shafts. Twenty patients were randomised to single buried IM K-wire fixation without postoperative immobilisation (Group A) or percutaneous transverse K-wire fixation followed by 4 weeks of splinting (Group B). Outcomes included metacarpophalangeal (MCP) joint range of motion (ROM), disabilities of arm, shoulder and hand (DASH) score, healing and complications, assessed at 4, 8 and 12 weeks. <b>Results:</b> Group A demonstrated significantly superior MCP joint ROM and lower DASH scores at 4 weeks postoperatively, with differences exceeding the MCID threshold. After K-wire removal, no differences in ROM or DASH scores were observed at 8 and 12 weeks. All patients achieved bone union. No malrotation, loss of reduction, wire migration, infection or fixation failure occurred in either group. <b>Conclusions:</b> Single IM K-wire fixation without postoperative splinting is safe and provides earlier functional recovery compared with conventional transverse K-wire fixation with immobilisation without affecting the final outcomes.

However, technical factors within the LCF may have an important influence on union and complication rates. <b>Methods:</b> This retrospective study evaluated the radiographic and functional outcomes of 28 patients (LCF = 19, 4CF = 9) treated between 2015 and 2023, with particular emphasis on technical observations within the LCF group. The 4CF cohort was primarily included to provide a clinical context. <b>Results:</b> The fusion rates were significantly lower in the LCF group (47% vs. 100%, <i>p</i> = 0.0098), and the reoperation rates were higher (32% vs. 0%, <i>p</i> = 0.136).

In contrast, the non-union rate was 43.8% (7/16) in the two-screw subgroup and 30.8% (4/13) when at least one fully threaded screw was used.

Although LCF is less extensive, its outcomes in this study appear to be influenced by technical factors. <b>Conclusions:</b> The main finding of this study was that non-union and reoperation in the LCF group were clustered in cases with less robust fixation constructs and potentially insufficient preparation of fusion surfaces. These observations imply that the outcome of LCF may depend more on the surgical execution than on the procedure itself. These findings should be considered hypothesis-generating.
