Free Tissue Transfer in Diabetic Foot Ulcers: A Systematic Review and Meta-Analysis.

Objective: Free tissue transfer is a powerful reconstructive method for patients with substantial diabetic foot ulcers. This study aimed to perform an updated systematic review and meta-analysis investigating the flap characteristics, concurrent revascularisation rates, complications, and outcomes associated with free tissue transfer in diabetic foot ulcers.

Methods: Two reviewers performed a systematic review of various databases since their inception, with no language restriction.

Automated CT Perfusion Detection of the Acute Infarct Core in Ischemic Stroke: A Systematic Review and Meta-Analysis.

Introduction: In patients with acute ischemic stroke, the location and volume of an irreversible infarct core determine prognosis and treatment. We aimed to determine if automated CT perfusion (CTP) is non-inferior to diffusion-weighted imaging (DWI) or fluid-attenuated inversion recovery (FLAIR) in predicting the acute infarct core.

Methods: In this systematic review and meta-analysis, we searched MEDLINE and EMBASE from 1960 to December 2020.

Radiographic Soft Tissue Thickness Differentiating Pyogenic Flexor Tenosynovitis From Other Finger Infections.

Purpose: Characteristic swelling has been described as a differentiating sign of pyogenic flexor tenosynovitis (PFT) but has not been validated. We conducted a retrospective study of adults with finger infections to compare radiographic parameters of soft tissue dimensions. Our hypothesis was that in patients with digit infections, radiographic soft tissue thickness measurement would differ between PFT and non-PFT infected digits.

Complications of pediatric distal radius and forearm fractures.

Distal radius and forearm fractures represent a large percentage of pediatric fractures. The most common mechanism of injury is a fall onto an outstretched arm, which can lead to substantial rotational displacement. If this rotational displacement is not adequately addressed, there will be resultant loss of forearm motion and subsequent limitations in performing the activities of daily living.

Salvage of upper extremities with humeral fracture and associated brachial artery injury.

Background: Humeral fractures with brachial artery injury present a challenge for treating surgeons. Treatment practices vary, including use of vascular shunts, multispecialty teams versus an upper-extremity surgeon, and temporizing external fixation. Our objectives were to describe our treatment approach, to define “absolute ischaemia,” to determine whether to use a vascular shunt, and to identify variables that could improve limb salvage rate.

Defining a safe zone of dissection during the extensor digitorum communis splitting approach to the proximal radius and forearm: an anatomic study.

Purpose: The extensor digitorum communis (EDC) splitting approach is a direct lateral approach that can provide greater visualization of the proximal radius than the posterolateral approach to the elbow. The purposes of this study were to identify the anatomic relationships of the posterior interosseous nerve (PIN) during the EDC splitting approach to the proximal radius and to determine its safe zone.

Methods: A fellowship-trained attending hand surgeon performed the EDC splitting approach on 15 cadaveric arms, exposing the EDC origin from the lateral epicondyle and dissecting distally to expose the supinator muscle.

Percutaneous pinning of distal radius fractures: an anatomic study demonstrating the proximity of K-wires to structures at risk.

Purpose: Closed reduction and percutaneous pinning is a reliable technique for treating 2- and 3-part distal radius fractures. There are currently no data that demonstrate the proximity of at-risk nerves and tendons during percutaneous placement of 5 commonly used K-wires. Whereas the previous literature notes the risk of superficial radial nerve injury with K-wire insertion into the radial styloid, the current study provides specific distances, not only to the superficial radial nerve (SRN) but also to the tendons of the first through fifth extensor compartments during K-wire insertion.

Dorsal displacement of the ulnar nerve after a displaced distal radius fracture: case report.

We report on a patient in whom ulnar nerve palsy developed after a closed distal radius fracture due to displacement of the ulnar nerve dorsal to the ulnar styloid. After delayed exploration and decompression of the ulnar nerve, the patient had recovery of both motor and sensory function of the ulnar nerve.

Long-term outcomes of closed reduction and percutaneous pinning for the treatment of distal radius fractures.

Purpose: The purpose of this study was to review the long-term outcomes of patients with distal radius fractures treated with closed reduction and percutaneous pinning.

Methods: We retrospectively reviewed 54 patients with 55 AO type A2, A3, C1, or C2 distal radius fractures treated with closed reduction and percutaneous pinning. The average age of the patients was 57 years.

Nonvascularized autogenous bone graft for extensive phalangeal bone loss: case report.

A 47-year-old man, a fine woodworker, sustained extensive phalangeal and soft tissue loss of his dominant left long and index fingers in a table saw injury. We report the long-term clinical and radiographic outcomes of the patient following reconstruction with corticocancellous iliac crest bone grafts. Rarely described in recent literature, we believe that primary nonvascularized autogenous bone grafting for phalangeal reconstruction is a worthwhile alternative to amputation when the soft tissue envelope is satisfactory.
