Distal biceps tendon repair using a double intracortical button anatomic footprint repair technique.

INTRODUCTION: Distal biceps tendon repair is usually performed via a double-incision or single-incision bicortical drilling technique. However, these techniques are associated with specific complications and usually do not allow for anatomic footprint restoration. It was the aim of this study to report the clinical results of a double intracortical button anatomic footprint repair technique for distal biceps tendon tears. We hypothesized that this technique would result in supination strength comparable to the uninjured side with a low rerupture rate and minimal bony or neurologic complications. MATERIAL AND METHODS: This was a retrospective, single-surgeon cohort study of a consecutive series of 22 patients with a mean (standard deviation) age of 50.7 (9.4) years and at least 1-year follow-up after distal biceps tendon repair. At final follow-up, complications, range of motion (ROM), the Patient-rated Elbow Evaluation (PREE), Mayo Elbow Performance Score (MEPS), Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire, visual analog scale (VAS) for pain, patient satisfaction, and supination strength in neutral as well as 60° of supination were analyzed. Radiographic evaluation was performed on a computed tomography scan. RESULTS: One patient (4.5%) experienced slight paresthesia in the area of the lateral antebrachial cutaneous nerve. Heterotopic ossification was seen in 1 patient (4.5%). All patients recovered full ROM except for 1 who had 10° of loss of flexion and extension. Median PREE score was 4.6 (0-39.6), median MEP was 100 (70-100), and median DASH score was 1.4 (0-16.7). All but 1 patient were very satisfied with the outcome. The affected arm had a mean of 98% (±13%) of neutral supination strength (P = .633) and 94% (±12%) of supination strength in 60° (P = .054) compared with the contralateral, unaffected side. There were 4 cases (18.2%) of cortical thinning due to at least 1 button and 1 case of button pullout (4.5%). CONCLUSIONS: The double intracortical button anatomic footprint repair technique seems to provide reliable restoration of supination strength and excellent patient satisfaction while minimizing complications, particularly nerve damage and heterotopic ossification.

Acromial and Scapular Spine Fractures following Reverse Total Shoulder Arthroplasty-A Systematic Review of Fixation Constructs and Techniques.

Fractures of the acromion and the scapular spine are established complications of reverse shoulder arthroplasty (RSA), and when they occur, the continuous strain by the deltoid along the bony fragments makes healing difficult. Evidence on treatment specific outcomes is poor, making the definition of a gold standard fixation technique difficult. The purpose of this systematic review is to assess whether any particular fixation construct offers improved clinical and/or radiographic outcomes. A systematic review of the literature on fixation of acromial and scapular spine fractures following RSA was carried out based on the guidelines of PRISMA. The search was conducted on PubMed, Embase, OVID Medline, and CENTRAL databases with strict inclusion and exclusion criteria applied. Methodological quality assessment of each included study was done using the modified Coleman methodology score to asses MQOE. Selection of the studies, data extraction and methodological quality assessment was carried out by two of the authors independently. Only clinical studies reporting on fixation of the aforementioned fractures were considered. Fixation construct, fracture union and time to union, shoulder function and complications were investigated. Nine studies reported on fixation strategies for acromial and scapular spine fractures and were therefore included. The 18 reported results related to fractures in 17 patients; 1 was classified as a Levy Type I fracture, 10 as a Levy Type II fracture and the remaining 7 fractures were defined as Levy Type III. The most frequent fixation construct in type II scapular spine fractures was a single plate (used in 6 of the 10 cases), whereas dual platin was the most used fixation for Levy Type III fractures (5 out of 7). Radiographic union was reported in 15 out of 18 fractures, whereas 1 patient (6.7%) had a confirmed non-union of a Levy Type III scapular spine fracture, requiring revision fixation. There were 5 complications reported, with 2 patients undergoing removal of metal and 1 patient undergoing revision fixation. The Subjective Shoulder Value and Visual Analogue Scale pain score averaged 75% and 2.6 points, respectively. The absolute Constant Score and the ASES score averaged 48.2 and 78.3 points, respectively. With the available data, it is not possible to define a gold standard surgical fixation but it seems that even when fracture union can be achieved, functional outcomes are moderate and there is an increased complication rate. Future studies are required to establish a gold standard fixation technique.

Platelet-rich plasma in non-operative management of mild to moderate carpal tunnel syndrome - A systematic review & meta-analysis of short-term outcomes.

BACKGROUND: To perform an updated systematic review with meta-analysis on trials focusing on patient-reported outcome measures (PROMs), nerve conduction studies (NCS) result and cross sectional area (CSA) measurements of those who underwent PRP injection for mild to moderate CTS, versus a control. CONCLUSION: This study indicates that there may be a potential role for the use of PRP in the non-operative management of mild to moderate CTS results in improvements in pain scores, functional outcomes as well as CSA measurements of the MN at short-term follow-up. However, PRP does not result in improvements in NCS. LEVEL OF EVIDENCE: II; Systematic Review & Meta-Analysis of Prospective Trials.

The majority of patients return to athletic activity following biceps tenodesis.

PURPOSE: Biceps tenodesis is widely used as a primary treatment for long head of the biceps brachii pathology and superior labral anterior and posterior (SLAP) lesions. However, rates and timing of full return to sports (RTSs)/duty have not been systematically analysed. This systematic review examines the literature to ascertain the rate and timing of return to athletic activity, and the availability of specific criteria for safe return to atheletic activity following the biceps tenodesis. METHODS: Based on PRISMA guidelines, this systematic review utilised the EMBASE, MEDLINE, and The Cochrane Library Databases. Eligible for inclusion were clinical studies reporting on return to athletic activity following biceps tenodesis. Statistical analysis was performed using SPSS. RESULTS: This review identified 17 studies including 374 cases meeting the inclusion criteria. The majority of patients were men 260 (69.7%), with an median age of 42.2 years (range 16-88) and a mean follow-up of 37.4 months. The overall rate of RTS was 217/269 (80.7%), with 43/59 (72.9%) returning to the same level. In overhead athletes, the overall rate of return to play was 39/49 (79.6%). Among military personnel, the overall rate of return to duty was 61/74 (82.4%). The average time to RTS was 5.4 (range 3-11) months. 10 (58.8%) Studies reported a recommended time window within which patients were allowed to return to full activity. Specific criteria for return to play were not reported in any of the identified studies. CONCLUSION: While overall rate of return to athletic activity was reportedly high following biceps tenodesis, one in four patients were not able to resume athletic activity at the same level. At present, there is no objective assessment of when patients can return to full activity reported in the literature. LEVEL OF EVIDENCE: IV.

Virtual Fracture Clinics in Orthopaedic Surgery - A Systematic Review of Current Evidence.

AIMS: Approximately 75% of fractures are simple, stable injuries which are often unnecessarily immobilised with subsequent repeated radiographs at numerous fracture clinic visits. In 2014, the Glasgow Fracture Pathway offered an alternative virtual fracture clinic (VFC) pathway with the potential to reduce traditional fracture clinic visits, waiting times and overall costs. Many units have implemented this style of pathway in the non-operative management of simple, undisplaced fractures. This study aims to systematically review the clinical outcomes, patient reported outcomes and cost analyses for VFCs. MATERIALS AND METHODS: Two independent reviewers performed the literature search based on PRISMA guidelines, utilizing the MEDLINE, EMBASE and COCHRANE Library databases. Studies reporting outcomes following the use of VFC were included. Outcomes analysed were: 1) clinical outcomes, 2) patient reported outcomes, and 3) cost analysis. RESULTS: Overall, 15 studies involving 11,921 patients with a mean age of 41.1 years and mean follow-up of 12.6 months were included. In total, 65.7% of patients were directly virtually discharged with protocol derived conservative management, with 9.1% using the Helpline and 15.6% contacting their general practitioner for advice or reassurance. A total of 1.2% of patients experienced fracture non-unions and 0.4% required surgical intervention. The overall patient satisfaction rate was 81.0%, with only 1.3% experiencing residual pain at the fracture site. Additionally, the mean cost per patient for VFC was £71, with a mean saving of £53 when compared to traditional clinic models. Subgroup analysis found that for undisplaced fifth metatarsal or radial head/neck fractures, the rates of discharge from VFC to physiotherapy or general practitioners were 81.2% and 93.7% respectively. DISCUSSION AND CONCLUSION: This study established that there is excellent evidence to support virtual fracture clinic for non-operative management of fifth metatarsal fractures, with moderate evidence for radial head and neck fractures. However, the routine use of virtual fracture clinics is presently not validated for all stable, undisplaced fracture patterns. LEVEL OF EVIDENCE: IV; Systematic Review of all Levels of Evidence.

Return to Play after Arthroscopic Bankart Repair Combined with Open Subpectoral Biceps Tenodesis.

PURPOSE: To evaluate the clinical outcomes and rate of return to play (RTP) in patients who underwent arthroscopic Bankart repair and open subpectoral biceps tenodesis. METHODS: A retrospective review of patients who underwent combined arthroscopic Bankart repair and open subpectoral biceps tenodesis by a single surgeon between 2012 and 2016 was performed. RTP, the level of return, and the timing of return were assessed. Visual analog scale for pain, Rowe score, Shoulder Instability-Return to Sport after Injury score, and Subjective Shoulder Value were evaluated. RESULTS: The study included 14 patients, with a mean follow-up of 34.2 ± 12.1 months. Of the 14 patients, 13 (92.9%) returned to sport at a mean of 4.8 ± 1.2 months and 9 (64.3%) returned to the same or higher level of sport. At final follow-up, the mean Rowe was 80.0 ± 16.3, the mean Subjective Shoulder Value was 81.0 ± 15.1, the mean Shoulder Instability-Return to Sport after Injury was 57.3 ± 25.6, and the mean visual analog scale score was 2.6 ± 1.5. One patient had a recurrent dislocation, whereas no patients underwent a further operation on the ipsilateral shoulder. CONCLUSION: Patients undergoing arthroscopic Bankart repair combined with open subpectoral biceps tenodesis had a high rate of RTP with a low rate of recurrent instability.

Is it safe for patients to drive after intra-articular knee injection?

BACKGROUND: Intra-articular knee injection is a central component in the current management of knee pain. While this is a routinely performed outpatient procedure, institutional policies for driving post injection differ. This study examines brake response times (BRTs) before and after intra-articular knee injection. Our hypothesis is that BRTs would not significantly differ and thus patients driving ability/safety is unaffected. METHODS: Forty-five patients previously listed for right intra-articular knee injection were prospectively evaluated. Patients underwent baseline assessment of BRT prior to injection. All patients received 10 ml of fluid consisting of one milliliter of 10 mg/ml triamcinolone mixed with nine milliliters of 0.5% levobupivacaine. BRT was re-examined on the same day prior to discharge home. Pre- and post-injection BRTs were examined using the same machine and assessor. RESULTS: The mean age of the cohort was 64.0 ± 12.4 and compromised of 37.8% males. There was no significant difference in the mean pre- and post-injection braking time (0.83 ± 0.29 vs 0.78 ± 0.30 s, p = .42), or in the rate of failed braking time (11.1% vs 6.7%, p = .46). CONCLUSION: This study found that BRT did not significantly differ before and after the intra-articular injection, nor did it cause an increased number of patients failing their BRTs. These findings suggest patients should not be prevented from driving after intra-articular knee injection.

Failed osteosynthesis of cemented B1 periprosthetic fractures.

BACKGROUND: Periprosthetic fractures about the hip are increasingly common. The literature estimates a failure rate of approximately 10% in Vancouver B1 type fractures which have undergone fixation. There is currently no guidance available on the next step of management for this patient group. This study presents a series of nine Vancouver B1 fractures with failed osteosynthesis and proposes that repeated fixation has poorer results than revision. METHODS: A total of nine patients (five women, four men) with a mean age of 71.2 years (52-83) underwent operative treatment for failed osteosynthesis of periprosthetic fractures of Vancouver type B1. Three patients were revised to a long revision stem while six patients had repeated osteosythesis. Failure was defined as the need for further operative intervention. RESULTS: The three patients revised to a long revision stem at first failure of osteosynthesis required no further surgical intervention. All six patients who had repeat osteoynthesis failed again. Five patients were subsequently successfully treated with revision of the primary stem, three were revised to a long revision stem while two patients required proximal femoral replacement. One patient died prior to revision. The mean follow up following initial B1 fracture was 49.3 months and following definitive operative intervention was 37.7 months. Six patients had died at 1st July 2017. CONCLUSION: Failed osteosynthesis of B1 fractures may necessitate revision rather than repeat fixation, regardless of how well fixed the stem appears. Revision to a long stem provided good results in this cohort.

Periprosthetic Fractures About the Hip: A Case-Matched Retrospective Analysis of Functional Outcomes Postrehabilitation.

INTRODUCTION: Little research has examined postrehabilitation functional outcomes of periprosthetic hip fractures. Predicted functional deficits and acceptable rehabilitation outcomes for these patients are not established. This study aimed to compare functional outcomes of periprosthetic fractures to matched patients with total hip arthroplasty (THA). MATERIALS AND METHODS: Cases with periprosthetic fracture (PPF) were matched for age, gender, and surgeon to primary THA cases. Only patients who had completed at least 1 year of rehabilitation were included. Western Ontario and McMaster Universities Arthritis Index (WOMAC) scores were calculated for all surviving cases with PPF and primary THA. Secondary outcomes included length of stay and mortality. Statistical analysis was performed using Microsoft Excel and the 2-tailed Wilcoxon signed rank test. A P value of <.05 was accepted as indicative of statistical significance. RESULTS: We identified 25 patients with PPF. Three patients were unsuitable for functional assessment. Of the cases with PPF suitable for functional assessment, 14 (14/22) were male. The median age of the PPF and the THA groups was 71 years and 68 years respectively. The median WOMAC score for the PPF group was 26 (interquartile range [IQR] 5.5-49.5) compared to that of the primary THA group, 3 (IQR 2.0-24.5; P < .05). In the PPF group, there were 7 deaths and 3 of the surviving patients had significant complications. The median length of stay in the PPF group was 13 days (IQR 10.5-35) compared to the matched group of 5 days (IQR 5-8.5; P < .05). CONCLUSION: Patients with PPF have markedly poorer functional outcomes than age-, gender-, and surgeon-matched patients with THA as well as prolonged length of stay. Future research should target the identification of factors that may improve functional outcomes in this growing cohort.

Developing a burn injury severity score (BISS): adding age and total body surface area burned to the injury severity score (ISS) improves mortality concordance.

BACKGROUND: There is limited research validating the injury severity score (ISS) in burns. We examined the concordance of ISS with burn mortality. We hypothesized that combining age and total body surface area (TBSA) burned to the ISS gives a more accurate mortality risk estimate. METHODS: Data from the Royal Perth Hospital Trauma Registry and the Royal Perth Hospital Burns Minimum Data Set were linked. Area under the receiver operating characteristic curve (AUC) measured concordance of ISS with mortality. Using logistic regression models with death as the dependent variable we developed a burn-specific injury severity score (BISS). RESULTS: There were 1344 burns with 24 (1.8%) deaths, median TBSA 5% (IQR 2-10), and median age 36 years (IQR 23-50). The results show ISS is a good predictor of death for burns when ISS≤15 (OR 1.29, p=0.02), but not for ISS>15 (ISS 16-24: OR 1.09, p=0.81; ISS 25-49: OR 0.81, p=0.19). Comparing the AUCs adjusted for age, gender and cause, ISS of 84% (95% CI 82-85%) and BISS of 95% (95% CI 92-98%), demonstrated superior performance of BISS as a mortality predictor for burns. CONCLUSION: ISS is a poor predictor of death in severe burns. The BISS combines ISS with age and TBSA and performs significantly better than the ISS.
