Direct anterior approach provides better functional outcomes when compared to direct lateral approach in hip hemiarthroplasty following femoral neck fracture.

PURPOSE: This study aims to compare the differences between direct anterior approach (DAA) and direct lateral approach (DLA) in hip hemiarthroplasty (HHA) after displaced femoral neck fracture (FNF) in early functional outcome, hospital length of stay, morbidity and mortality rates. METHODS: This non-interventional retrospective study, carried out at a tertiary trauma centre within the Spanish National Health System, included all patients who underwent a bipolar HHA between 1st January 2018 and 31st December 2019 performed by 2 of our hip unit surgeons. RESULTS: A total of 94 patients were included (40 in DAA group and 54 in DLA group). Median follow-up was 19.2 months (range 8-30.8 months). Postoperative degree of mobilisation showed statistically significant differences in favour of DAA group, where 35% of patients were able to walk with no assistance after surgery. DAA group had 1 day less of hospitalisation in contrast with DLA group overall (8 days vs 9 days, respectively, p < 0.05). Statistically significant differences were not detected in comparing postoperative complications, re-operations rates or 6-months mortality rate. CONCLUSION: Our study highlights the benefits of DAA for HHA after displaced FNF in terms of postoperative mobilisation degree and hospitalisation length of stay when compared to DLA.

Balancing mesh-related complications and benefits in primary ventral and incisional hernia surgery. A meta-analysis and trial sequential analysis.

BACKGROUND: Primary ventral hernia (PVH) and incisional hernia (IH) repair using a mesh appears to reduce hernia recurrence. However, are the benefits of mesh offset in part by mesh-related complications? The aim of this study was to compare placement of a mesh versus simple suture for recurrence and postoperative complications in the repair of PVH or IH. METHODS: Five databases were searched for randomized controlled trials (RCTs). The study population was patients with a PVH or IH undergoing hernia repair. Intervention was placement of a nonabsorbable synthetic mesh, regardless of mesh location, surgical technique, hernia characteristics or surgical setting compared to primary suture. Primary outcome was the incidence of hernia recurrence. Secondary outcomes were wound infection, hematoma, seroma, postsurgical pain, duration of operation, and quality of life. A random-effects meta-analysis with trial sequential analysis (TSA) was used. RESULTS: 10 RCTs with a total of 1270 patients were included. A significant reduction of the incidence of PVH or IH recurrence using a mesh for repair (risk ratio [RR] 0.39, 95% CI 0.27-0.55; P < 0.00001; I2 = 20%) was observed. TSA for recurrence, the accrued information size (1270) was 312% of the estimated required information size (RIS). Subgroup analysis for PVH and IH confirms reduction of recurrence after using a mesh in both groups. Overall postoperative complications did not show statistically significant differences between the mesh and surgical suture groups (RR 1.31, 95% CI 0.94-1.84; P = 0.12; I2 = 27%) but the accrued information size was only 22.4% of RIS and by subgroups complications were only related with IH repair. CONCLUSIONS: Evidence for the efficacy of repair of PVH or IH using a nonabsorbable synthetic mesh in terms of recurrence was found to be robust. Evidence for complications remains inconclusive.
