  • The aim of this systematic review and meta-analysis was to assess risk for iatrogenic radial nerve palsy (iRNP), non-union, and post-operative infection in humeral shaft fractures.

  • A PubMed search including original articles comparing different treatments for humeral shaft fractures published since January 2000 was performed. Random effect models with relative risks (RR) and 95% CIs were calculated for treatment groups and outcomes.

  • Of the 841 results, 43 studies were included in the meta-analysis (11 level II, 5 level III, 27 level IV). Twenty-seven compared intramedullary nailing (IM) with ORIF, nine conservative with operative treatment, four ORIF with minimally invasive plate osteosynthesis (MIPO), and three anterior/anterolateral with posterior approach. iRNP risk was higher for ORIF vs IM (18 studies; RR: 1.80; P  = 0.047), ORIF vs MIPO (4 studies; RR: 5.60; P  = 0.011), and posterior vs anterior/anterolateral approach (3 studies; RR: 2.68; P  = 0.005). Non-union risk was lower for operative vs conservative therapy (six studies; RR: 0.37; P  < 0.001), but not significantly different between ORIF and IM (21 studies; RR: 1.00; P  = 0.997), or approaches (two studies; RR: 0.36; P  = 0.369). Post-operative infection risk was higher for ORIF vs IM (14 studies; RR: 1.84; P  = 0.004) but not different between approaches (2 studies; RR: 0.95; P  = 0.960).

  • Surgery appears to be the method of choice when aiming to secure bony union, albeit risk for iRNP has to be considered, particularly in case of ORIF vs IM or MIPO, and posterior approach. Due to the limited number of randomised studies, evidence on the best treatment option remains moderate, though.

  • The aim of this study was to determine whether all-arthroscopic repair would lead to improved clinical outcomes, lower complication rates, shorter postoperative immobilization and earlier return to activity compared to open Broström repair in the surgical treatment of chronic lateral ankle instability (CLAI).

  • A systematic literature search was conducted using Pubmed and Embase to identify studies dealing with a comparison of outcomes between all-arthroscopic and open Broström repair for CLAI. The search algorithm was ‘ankle instability’ AND ‘Brostrom’ AND ‘arthroscopic’ AND ‘open’. The study had to be written in English language, include a direct comparison of all-arthroscopic and open Broström repair to treat CLAI and have full text available. Exclusion criteria were former systematic reviews, biomechanical studies and case reports.

  • Overall, eight studies met the inclusion criteria and were included in the analysis. Clinical outcomes did not differ substantially between patients treated with either arthroscopic or open Broström repair. Studies that reported on return to activity and sports following surgery suggested that patients that had all-arthroscopic Broström repair returned at a quicker rate. Overall complication rate tended to be lower after arthroscopic Broström repair.

  • Similar to open repair, all-arthroscopic ligament repair for CLAI is a safe treatment option that yields excellent clinical outcomes.

  • Level of Evidence: Level III evidence (systematic review of level I, II and III studies).
