Aim

Decubitus ulcers are found in approximately 4.7% of hospitalized patients, with a higher prevalence (up to 30%) among those with spinal cord injuries. These ulcers are often associated with hip septic arthritis and/or osteomyelitis involving the femur. Girdlestone resection arthroplasty is a surgical technique used to remove affected proximal femur and acetabular tissues, resulting in a substantial defect. The vastus lateralis flap has been employed as an effective option for managing this dead space. The aim of this study was to evaluate the long-term outcomes of this procedure in a consecutive series of patients.

Aim

There are no studies in literature that analyze the effectiveness of closed-incisional negative pressure wound therapy (ciNPWT) in the treatment of bone and joint infections (BJI). The aim of the study was to evaluate the efficacy and the safety of the application of ciNPWT in the postsurgical wound management of patients with osteoarticular infections.

Introduction

the aim of the study is to evaluate the clinical results of the shoulder prosthesis revision procedure to reverse implant without removing the humeral stem using a modular system (Lima LTD) and determine if this procedure is beneficial for the patients.

Aims: Most of the orthopaedic literature on os acromiale (OA) is focused on corresponding clinical implication, such as impingement syndrome and rotator cuff tear; whilst, although it is present in 8% of subjects, scarce information is reported on the causes that may predispose to it. Our aim is to investigate whether the origin of OA is related to position of AC joint. Methods: The acromions of 211 volunteers (control group) and 33 subjects, respectively, without or with OA have been radiographically (axillary view) classiþed in accordance to the Edelson and Taitzñ method. The latter distinguishes the acromion in three types on the basis of the distance between the anterior aspect of the acromion and AC joint. Out of 33 subjects with os acromiale, 11 were shoulder painless. We have compared among them the frequencies of the types of acromion observed in the two investigated cohorts. Results: Half (52.1%) of the acromions of the control group had the articular facet for the AC joint on the acromion tip whilst in 45.4% facet was tip distally located. On the other hand, out of 33 subjects with OA, 18.1% and 81.1% had, respectively, AC joint lying on or distally to the acromion tip. Conclusions: Our data suggest that the longer is the distance of AC joint from the anterior edge of the acromion, the higher is the possibility that an OA origin.

Aims: We studied the prevalence of calciþc tendinopathy in asymptomatic subjects and the relationship between calciþc deposits and the anatomopathological characteristic of coracoacromial arch. Methods: 222 right-handed volunteers underwent x-ray examination of the right shoulder. We measured the acromiohumeral distance (AHD) and evaluated the acromion shape and the degenerative changes of the GH and AC joints. We measured the size of the deposits and classiþed the calciþcations based on their location, shape and neatness. The subjects with deposits were clinically evaluated and underwent a second x-ray study after 14 months. Results: 11 subjects (5%) had calciþcation. The latter was in the substance of supraspinatus in 5(mean age 45 yrs) and at cuff insertion in 6 (66 yrs). The deposits measured 0.7±0.3cm (avg). There were 3 linear and 2 beanlike intratendinous calciþcations and 5 linear and 1 beanlike deposits at tendon insertion. Calciþcations had well-deþned margins. AHD, acromion shape, arthritic of the GH or AC joint were unrelated to the presence of calciþcations. No subject showed evidence of cuff tear. Intratendinous deposit decreased in size in 2 cases and disappeared in 1. Conclusions: 5% of asymptomatic subjects have calciþcations. Calciþcations are always small and well-deþned. Morphology and changes of the cora-coacromial arch or the GH or AC joint donñt inßuence the deposition of calcium. Our study suggests that calciþcations may decrease in size or disappear without completion of Uhthoffñs cycle.
