Treatment of midshaft clavicular delayed and non-unions with anteroinferior locking compression plating

INTRODUCTION: Pain and impaired shoulder function are the predominant symptoms of midshaft clavicle non-unions. Obtaining consolidation and improvement of shoulder function is often successfully achieved with osteosynthesis and bone grafting. Most data in the literature pertain to plate osteosynthesis, placing the plate on the subcutaneous superior aspect of the clavicle. Although union rates are generally high, most patients require hardware removal as the plate is prominent under the skin causing pain and cosmetic problems. MATERIALS AND METHODS: In the current retrospective study, we followed a cohort of 21 consecutive cases (20 patients) with a midshaft clavicular delayed or non-union, treated with anteroinferior plating using a 3.5 mm locking compression plate (LCP) for a mean of 30 months. RESULTS: We operated on 10 males and 10 females with a mean age of 48.2 years (range 16-65). There was one early plate failure that needed revision. Two patients required hardware removal because of prominence of the plate. All but two patients were satisfied with the final cosmetic result. The average DASH score at follow up was 22.8. DISCUSSION AND CONCLUSIONS: Anteroinferior plating with a 3.5 mm LCP is a reliable and reproducible treatment of midshaft clavicular delayed and non-union regarding consolidation, function, cosmesis and reduction of second surger

Measuring hindfoot alignment radiographically: the long axial view is more reliable than the hindfoot alignment view

BACKGROUND: Hindfoot malalignment is a recognized cause of foot and ankle disability. For preoperative planning and clinical follow-up, reliable radiographic assessment of hindfoot alignment is important. The long axial radiographic view and the hindfoot alignment view are commonly used for this purpose. However, their comparative reliabilities are unknown. As hindfoot varus or valgus malalignment is most pronounced during mid-stance of gait, a unilateral weight-bearing stance, in comparison with a bilateral stance, could increase measurement reliability. The purpose of this study was to compare the intra- and interobserver reliability of hindfoot alignment measurements of both radiographic views in bilateral and unilateral stance. MATERIALS AND METHODS: A hindfoot alignment view and a long axial view were acquired from 18 healthy volunteers in bilateral and unilateral weight-bearing stances. Hindfoot alignment was defined as the angular deviation between the tibial anatomical axis and the calcaneus longitudinal axis from the radiographs. Repeat measurements of hindfoot alignment were performed by nine orthopaedic examiners. RESULTS: Measurements from the hindfoot alignment view gave intra- and interclass correlation coefficients (CCs) of 0.72 and 0.58, respectively, for bilateral stance and 0.91 and 0.49, respectively, for unilateral stance. The long axial view showed, respectively, intra- and interclass CCs of 0.93 and 0.79 for bilateral stance and 0.91 and 0.58 for unilateral stance. CONCLUSION: The long axial view is more reliable than the hindfoot alignment view or the angular measurement of hindfoot alignment. Although intra-observer reliability is good/excellent for both methods, only the long axial view leads to good interobserver reliability. A unilateral weight-bearing stance does not lead to greater reliability of measuremen

Platelet-Rich Plasma Injections for the Treatment of Ankle Osteoarthritis

Background: Ankle osteoarthritis is debilitating and usually affects relatively young people, often as a result of previous ankle traumas, frequently occurring in sports. Platelet-rich plasma (PRP) injections for ankle osteoarthritis have shown no evidence of benefit over the course of 26 weeks. Previous studies on PRP for knee osteoarthritis showed that clinically significant improvements with PRP occurred between 6 to 12 months in the absence of initial benefit. No studies have evaluated the effect of PRP from 6 to 12 months in ankle osteoarthritis. Purpose: To assess the efficacy of PRP injections in ankle osteoarthritis over the course of 52 weeks. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: In this 52-week follow-up trial, 100 patients with ankle osteoarthritis were randomized to a PRP group or placebo (saline) group. Patients received 2 intra-articular talocrural injections: at inclusion and after 6 weeks. Patient-reported outcome measures were used to assess pain, function, quality of life, and indirect costs over 52 weeks. Results: Two patients (2%) were lost to follow-up. The adjusted between-group difference for the patient-reported American Orthopaedic Foot &amp; Ankle Society score over 52 weeks was −2 points (95% CI, −5 to 2; P =.31) in favor of the placebo group. No significant between-group differences were observed for any of the secondary outcome measures. Conclusion: For patients with ankle osteoarthritis, PRP injections did not improve ankle symptoms and function over 52 weeks compared with placebo injections. Registration: NTR7261 (Netherlands Trial Register).</p

Update Sprunggelenksprothetik

Ankle arthritis is a major cause of impaired quality of life and affects approximately 1 % of the world population. Treatment options in end stage arthritis include ankle arthrodesis and total ankle replacement. As ankle arthroplasty preserves motion at the ankle joint it has become a popular alternative to fusion. Due to modern implantation techniques and improved prothesis designs ankle arthroplasty has emerged as a safe and effective treatment of ankle arthritis

Triple arthrodesis

Triple arthrodesis is largely used to restore painful hindfoot deformity. However, the procedure has been connected to several postoperative complications. Therefore, an isolated fusion of the talonavicular and the subtalar joint through a single medial approach has gained popularity. This "diple" arthrodesis provides effective correction of deformities and reduces the risk of wound healing problems on the lateral side of the foo

Cartilage lesions and the development of osteoarthritis after internal fixation of ankle fractures : a prospective study

The role of the location and severity of the initial cartilage lesions associated with an ankle fracture in the development of posttraumatic osteoarthritis has not been established, to our knowledge
