Topical Negative Pressure Wound Dressing and Its Applications in the Hand-A Review of the Literature.

The use of topical negative pressure wound therapy (NPWT) has become increasingly popular in the management of complex wounds. There are many theories as to the mechanism of action of NPWT, but the essential components of the various systems remain consistent. There are many attractive potential properties of negative pressure dressings that lend themselves to the management of upper limb injuries. This article explores the technique of negative pressure wound dressing, the theories pertaining to mechanism of action, and the increasingly broad indications described for the use of NPWT in the hand. The literature pertaining to the efficacy of NPWT in general is also discussed.

Predicting factors for better outcomes of stable supination external rotation type 2 ankle fractures.

PURPOSE: Stable Weber B ankle fractures are treated by a walking boot for 6 weeks and bearing full weight through the boot as tolerated. The aim of the present study was to assess the outcome parameters of this treatment protocol, evaluate the efficacy of using the walking boot, and investigate any possible predicting factors that could affect the outcomes. METHODS: All the patients with stable Weber B ankle fractures, treated in our hospital between January 2018 and December 2018, were prospectively included to the study. The patients were evaluated clinically, and the patient-reported outcome measures data were collected at the 2 and 6 weeks post-injury. Chi square, Spearman's rho test, independent samples and paired sample t-tests were used for the monovariant analysis. RESULTS: A total of 128 consecutive patients (aged 52.2 ± 19.1 years) with supination external rotation type 2 fracture were finally included to the study. At the 2 weeks follow-up, the reported outcome measures scores were in moderate levels, but improved significantly at the 6 weeks follow-up (p < 0.0001). Multivariant analysis revealed that the ability to bear full weight without the boot at the 2 weeks after diagnosis was the only variable, which made statistically unique contribution to the foot and ankle disability index score at the 6 weeks (p = 0.005). CONCLUSION: Conservative treatment using a walking boot with advice to bear full weight of stable ankle Weber B fractures can bring to good functional outcomes. The ability to bear full weight without the aid of the walking boot at 2 weeks after diagnosis was the only significant predicting factor for better outcomes at 6 weeks after diagnosis.

Indications, Outcomes, and Complications of Lateral Ulnar Collateral Ligament Reconstruction of the Elbow for Chronic Posterolateral Rotatory Instability: A Systematic Review.

BACKGROUND: Posterolateral rotatory instability (PLRI) of the elbow can lead to pain, recurrent dislocations, and, in the worst-case scenario, disability. PURPOSE: To report the indications, outcomes, and complication rates of lateral ulnar collateral ligament (LUCL) reconstruction for chronic PLRI of the elbow. STUDY DESIGN: Systematic review. METHODS: This systematic review was registered with PROSPERO and performed in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The review entailed 17 studies that included 168 patients with isolated LUCL reconstruction for chronic PLRI. Patients with concurrent medial collateral ligament reconstruction were excluded. The primary outcome measures were patient characteristics, indication for surgery, surgical technique, functional outcomes, and complications. RESULTS: Chronic PLRI commonly occurred after a previous traumatic injury (n = 168). Of these, there were 119 simple instabilities (no fracture) and 33 complex instabilities (associated fracture). In 11 patients, PLRI was iatrogenic. The cause was unknown in 5 patients. Grafts used were autograft (n = 102; 61%), allograft (n = 18; 11%), synthetic graft (n = 15; 9%), and unknown (n = 33; 20%). The most common surgical technique was a docking procedure or a modification of this (n = 145; 86%). Other techniques included suture anchors (n = 18; 11%), nonanatomic (n = 1; 0.6%), and unknown (n = 4; 2%). There were 45 complications reported in 37 patients (22%). The most frequent complication was recurrent instability (21/138; 15%). No other major complications were reported. The rate of recurrent instability was significantly higher in revision reconstructions (6/15 elbows; 40%) compared with primary reconstructions (15/123 elbows; 12.2%) (P = .005). The mean Mayo Elbow Performance Score and abbreviated Disabilities of the Arm, Shoulder and Hand score were 87.5 (range, 40-100) and 18.8 (range, 0-77), respectively. Of the patients in whom range of motion was measured, 134 of 144 patients (93%) regained a functional range (30L-130L). CONCLUSION: LUCL reconstruction for chronic PLRI proved a reliable method of reconstruction, save for the moderate rate of recurrent instability, which was highest in revision reconstructions.
