Does a skin incision along Langer's lines reduce complications following fixation of displaced middle-third clavicle fractures?

INTRODUCTION: Internal fixation of displaced middle-third clavicle fractures is a widely used treatment but is frequently associated with post-operative complications. The aim of this study is to investigate whether or not using a skin incision along Langer's lines, as opposed to a traditional transverse incision, reduces complications. METHODS: We retrospectively reviewed data on 108 patients who underwent open reduction and internal fixation of mid-shaft clavicle fractures between 2014 and 2018. Either an oblique incision along Langer's lines or a transverse incision was used according to surgeon's preference. A pre-contoured diaphyseal locking plate was used in all cases. We collected data on fracture classification, minor complications (irritation from plate, chest wall numbness, superficial wound infection) and major complications (irritation from plate necessitating metalwork removal, periprosthetic fracture, deep infection, neurovascular injury and non-union). Statistical analysis was performed using multivariant regression analysis and Fisher's exact tests. RESULTS: Fifty-seven patients underwent fixation using the oblique incision and 51 via the transverse incision. Age, gender and fracture pattern in the two groups were comparable. There were 14 minor and 6 major complications in the oblique group. In the transverse group, there were 16 minor and 5 major complications. The major complication rate was 10.5% in the oblique group and 9.8% in the transverse group. The overall major complication rate was 10.2%. No statistically significant difference in the rate of complications between the two groups was identified. CONCLUSION: Based on our data, an incision following Langer's lines does not reduce the rate of complications following fixation of displaced middle-third clavicle fractures.

A New "Trapdoor technique" for Fixation of Displaced Greater Tuberosity Fractures of the Shoulder.

Isolated greater tuberosity fractures of the proximal humerus are frequently displaced posteriorly and superiorly by the pull of the rotator cuff. This displacement can lead to a decline in function if left untreated. Traditionally these fractures have been treated surgically using screw fixation. On occasions this metalwork can remain prominent and potentially cause impingement. We present a new surgical "trapdoor" technique for fixation of isolated greater tuberosity fractures which can avoid these problems and be utilised either open or arthroscopically. Following reduction of the isolated greater tuberosity fragment, two double loaded metal screw in anchors are placed through stab incisions in the rotator cuff at the bone-tendon interface and secured into the humeral head. A suture from each of the anchors is tied together to secure the tuberosity fragment proximally and a suture-less anchor is inserted distal to the fracture site forming an inverted triangle. The remaining sutures are placed through the suture-less anchor and tensioned independently. As the sutures are tied and snugged tight, the distal aspect of the fracture reduces, thus closing the "trapdoor." This is a newly described versatile technique that can be used regardless of the size and comminution of the tuberosity fragment and can be performed either open or arthroscopically. It avoids the problems of metalwork prominence and irritation and the use of the suture-less anchor allows independent tensioning of the sutures to ensure adequate fracture reduction.

A Reproducible Technique for Arthroscopic Acromioclavicular Joint Excision.

Arthroscopic acromioclavicular joint excision is a commonly performed but technically demanding procedure. Incomplete excision can leave residual symptoms. We present a simple, reproducible technique ensuring satisfactory excision of the joint.

Open reduction and fixation of displaced lateral clavicle fractures using the Minimally Invasive Acromioclavicular Joint Reconstruction (MINAR®) technique: a case series review.

BACKGROUND: Lateral end of clavicle fractures can be a challenge, with a 20% to 30% non-union rate if treated non-operatively. Several operative options exist, each having their own merits and some having potential disadvantages. The Minimally Invasive Acromioclavicular Joint Reconstruction (MINAR®) (Storz, Tutlingen, Germany) set uses an Orthocord (Depuy Synthes Mitek, Leeds, UK) suture and two Flip Tacks (Storz) via a transclavicular-coracoid approach to reconstruct the coracoclavicular ligaments. METHODS: Referrals were made to two senior surgeons at separate institutions regarding Robinson Type 3 fractures of the lateral end of the clavicle. All patients were treated with MINAR implant via a minimally invasive approach. Two-year follow-up was obtained using the Oxford Shoulder Score (OSS) and the Quick DASH (Disability of the Arm Shoulder and Hand) score. RESULTS: Sixteen cases of acute fractures of the lateral end of the clavicle were included in this series. At final follow-up, the mean OSS was 44.75 (range 35 to 48) and the median Quick DASH score was 2.3 (range 0 to 35.9). Fifteen patients achieved bony union (one asymptomatic non-union) and there were no complications or re-operations. CONCLUSIONS: The MINAR is reproducible and safe when treating lateral end of clavicle fractures. We consider that, over the short- to mid-term, it achieves results equivalent to those for other implants.

Arthroscopic suprascapular neurotomy for the painful irreparable rotator cuff tear.

BACKGROUND: Massive irreparable rotator cuff tears are becoming increasingly difficult to manage. METHODS: Patients were considered for treatment if they had a painful shoulder in the presence of a compensated cuff tear. All patients had radiological evidence of a massive irreparable cuff tear and underwent suprascapular neurotomy, arthroscopically. RESULTS: There were 15 males and 25 females with a mean age of 74 years (range 59 years to 88 years). The mean pre-operative Oxford Shoulder Score (OSS) in all patients was 17.7, with a mean pre-operative visual analogue score (VAS) of 8.0. The mean post-operative OSS was 30.8 [27.42-34.18 = confidence interval (CI) 95%] with a mean VAS of 3.6 (2.64-4.56 CI 95%) at the 3-month (short-term) period (n = 32). The medium-term (1-year) OSS and VAS had improved to 33.6 (32.27-34.93 = CI 95%) and 3.7 (0-8.39 CI 95%) respectively (n = 26). The difference pre- and postoperatively at 12 months was statistically significant (p < 0.001). Patients who underwent biceps tenotomy at the time of surgery had a less significant improvement in their VAS and OSS. CONCLUSIONS: Suprascapular neurotomy can afford medium-term benefit in over two-thirds of the patients who would otherwise have undergone reverse polarity shoulder replacements. We consider that this is a reproducible technique.

The use of hip radiographs in primary care: the inter-observer agreement of reporting native hip pathology.

INTRODUCTION: Plain radiographs are often the first line investigation in identifying the cause of hip pain, though they do not differentiate all morphologically normal and abnormal hips. Interpretation of radiographs is subjective, depending on the patient history and physical signs. A radiological report can be misleading and may lead to, unnecessary radiation exposure, a delay in referral and a delay to definitive treatment. This study was to investigate the inter-observer reliability in the reporting of plain radiographs. METHODS: Sixty-one consecutive antero-posterior (AP) radiographs of native hips were identified that had been referred to one of the senior authors from the community with "hip pain". Images were anonymised within PACS (picture archiving and communication system) and reviewed by a consultant orthopaedic surgeon, two consultant musculoskeletal radiologists, one senior orthopaedic registrar and one senior radiology registrar. Each reviewer was given a pre-constructed proforma, and asked to report the radiographs. RESULTS: There is a varying degree of 'agreement' for many of the commonly used terms on a hip radiograph. Agreement between all observers varied, by description, between 23.3% (CAM Lesion) to 93.3% (AVN). Multi-rater agreement showed Kappa values ranging from 0.12 (poor) to 0.6 (moderate). Overall there were widespread inconsistencies, even amongst the most widely used terms. CONCLUSION: There is variable agreement amongst musculoskeletal radiology and orthopaedic experts when analysing plain radiographs of the native hip. This has implications for utility of reporting and therefore treatment in the community setting.

An atypical presentation of hallucial sesamoid avascular necrosis: a case report.

UNLABELLED: Sesamoid bone disorders are a rare cause of metatarsal pain and can be difficult to diagnose. This article describes an atypical case of avascular necrosis of the fibular sesamoid in a 62-year-old male. Avascular necrosis of the sesamoid is an infrequent and incompletely defined process. The case described in this report is somewhat atypical as this condition is usually associated with female sex, adolescence, or a precipitating factor of minor trauma. LEVEL OF CLINICAL EVIDENCE: 4.

Phase II trial of alfimeprase, a novel-acting fibrin degradation agent, for occluded central venous access devices.

PURPOSE: Alfimeprase is a recombinantly produced, genetically modified variant of the metalloproteinase, fibrolase. Alfimeprase proteolytically cleaves fibrin, independent of plasminogen activation to plasmin, and directly dissolves thrombi. Based on the direct fibrin degradation effect of alfimeprase, rapid activity in patients with occluded central venous access devices (CVADs) was hypothesized. PATIENTS AND METHODS: We performed a phase II, randomized, double-blind, active-control, multicenter, dose-ranging study to compare the safety and efficacy of one or two instillations of three intraluminal doses of alfimeprase (0.3, 1.0, and 3.0 mg) and alteplase 2.0 mg in re-establishing patency to occluded CVADs in 55 adult patients. RESULTS: All three alfimeprase doses were more successful than alteplase during the first 15 and 30 minutes of treatment. The alfimeprase 3.0-mg dose resulted in 40%, 50%, and 60% patency restoration rates at 5, 15, and 30 minutes, respectively, compared with 0%, 0%, and 23% for alteplase. The difference at 15 minutes was highly significant (P = .0075). Alfimeprase 3.0 mg produced the highest patency rate at 120 minutes after the first (60%) and second (80%) doses. No major hemorrhagic or embolic events were reported. CONCLUSION: A single 1- or 3-mg dose of alfimeprase has the potential to restore function to occluded CVADs rapidly and safely, and to facilitate on-time infusion of vital therapies.

The relation between health-related quality of life, past medical history, and American Society of Anesthesiologists' ASA grade in patients having primary operations for oral and oropharyngeal cancer.

Pre-existing medical problems have the potential to affect postoperative survival, complications, and health-related quality of life (QoL). Our aim was to explore the relation between past medical history, American Society of Anesthesiologists' (ASA) score, health-related QoL, and survival. We collected data from 278 consecutive patients with previously untreated oral and oropharyngeal squamous cell carcinoma operated on primarily from 1995 to 1999 inclusive. Past medical history was recorded from the case notes, ASA grade from the anaesthetic record, and QoL was measured using the University of Washington Quality of Life Questionnaire (UW-QoL). Responses to questionnaires were received from (71%) at baseline (63%) at 6 months (73%) at 1 year, and (65%) 18 months or longer. Past medical history was associated with lower ASA scores. At baseline both history and ASA scores were related to the UW-QoL. Longitudinally patients in ASA grade 1 or with no past history scored better in these UW-QoL domains. Past history did not predict survival (P = 0.83), nor did the UW-QoL composite score (P = 0.30), whilst ASA was associated with crude survival (P = 0.003) and disease-specific survival (P = 0.03). When analyses were stratified for adjuvant radiotherapy, type of operation, size of tumour, and age then the relation to ASA was maintained and trends in the past history and UW-QoL remained not significant. ASA, which is often recorded as part of preoperative assessment, reflects both survival and health-related QoL, and is more useful than past history alone for predicting outcome.
