The Efficacy of Posterior Fasciotomy Versus Inserted Vacuum Drainage in Reducing Postoperative Surgical Site Infection in Open Achilles Tendon Repair: A Prospective Cohort Study With Inverse Probability Treatment Weight Propensity Score Analysis.

Posterior crural fasciotomy (PF) may reduce postoperative surgical site infection (SSI) rate compared to inserted vacuum suction drainage (VD) in open Achilles tendon repair surgery. Thus, we aimed to compare the postoperative SSI rate between PF and VD in open Achilles's tendon repair surgery. A prospective, single-centered, nonrandomized controlled study of consecutive adult patients undergoing primary open Achilles tendon repair was performed at tertiary referral hospital between January 2017 and January 2020. Patients received either PF or VD from 2 experienced surgeons. Data were collected on demographic, clinical, and intraoperative characteristics along with postoperative SSI and other outcomes. The primary outcome was SSI rate. Secondary outcomes were Achilles tendon total rupture score, functional foot index, and visual analogue scale. A total of 60 patients were eligible and included in the final analysis (PF group n = 30 and VD group n = 30). Two (6.7%) patients in the PF group and 5 (16.7%) patients in the VD group experience postoperative SSI (crude risk ratio 0.40; 95% confidence interval 0.08, 1.90; p = .228). In inverse-probability-treatment-weighted propensity score analysis, the PF group had a significantly lower SSI rate than the VD group (adjusted risk ratio 0.30; 95% confidence interval 0.01, 0.91; p = .033). Inverse-probability-treatment-weighted propensity score analysis of Achilles tendon total rupture score along with crude analysis of total functional foot index and visual analogue scale were also significantly better in the PF group than the VD group (all p < .05). PF during open Achilles repair was associated with a significant reduction in postoperative SSI infection rate compared to VD.

Combined medial gastrocnemius and hemisoleus flap: a reproducible alternative for open tibial fractures complicated with large or double soft tissue defects.

BACKGROUND: Utilization of combined local muscle flaps for Gustilo type IIIB open tibial fractures has not been clearly delineated. We describe a combination of medial gastrocnemius and hemisoleus flaps for managing open tibial fractures accompanying large or double soft tissue defects. METHODS: Twelve patients with Gustilo IIIB open fractures of the tibial shaft with large (9) or double (3) defects were operated on by fracture stabilization and combined medial gastrocnemius and hemisoleus flap coverage. Data were collected on types of implants, types of flaps, union time, postoperative complications, and Puno functional scores. RESULTS: Regarding implants for fixation, an intramedullary nail was used in three patients, plate and screws in five, combined plate and intramedullary nail in one, and definitive external fixation was used in three. Regarding soft tissue coverage, combined medial gastrocnemius and hemisoleus flaps were used in ten patients, combined hemigastrocnemius and hemisoleus in one, and combined medial gastrocnemius and reversed hemisoleus in one. All flaps survived, and all fractures were united with a mean union time of 19.7 weeks (range 16-24). Tip necrosis of the hemisoleus flap occurred in two patients. Regarding Puno functional score, one was determined to be excellent, nine was good and two was fair. CONCLUSION: Combined medial gastrocnemius and hemisoleus flaps are reliable and effective for open tibial fractures complicated with large or double soft tissue defects.
