Postoperative outcomes of total elbow replacement in haemophilic elbow arthropathy: A systematic review.

INTRODUCTION: Total elbow replacement (TER) is a surgical treatment option for haemophilic elbow arthropathy. AIM: To review the outcomes of TER in haemophilic elbow arthropathy. The primary outcome measures were perioperative blood loss, postoperative complications, revision rates and length of hospital stay (LOS). Secondary outcomes were elbow range of motion (ROM), functional outcome scores and the visual analogue pain scale (VAS). MATERIALS AND METHODS: PubMed, Medline, Embase and the Cochrane register were searched conforming to the PRISMA guidelines. Only studies with a minimum postoperative follow-up of 1 year were included. Quality appraisal was performed utilizing the MINORS criteria. RESULTS: One hundred and thirty-eight articles were identified. Following article screening, only seven studies met the inclusion criteria. A total of 51 TERs in 38 patients were performed, with the Coonrad-Morrey prosthesis utilized in 51% of cases. The pooled postoperative complication and revision rates were 49% and 29%, respectively. Surgery-related postoperative mortality was 3.9%. The mean preoperative Mayo elbow performance score (MEPS) was 43 ± 20 whereas the mean postoperative MEPS was 89 ± 6. Mean preoperative VAS was 7.2 ± 1.9 while the mean postoperative VAS was 2.0 ± 1.4. Mean preoperative and postoperative elbow flexion arcs were 54 ± 15 and 91 ± 10 degrees, respectively. Mean preoperative and postoperative forearm rotation arcs were 86 ± 40 and 135 ± 19 degrees, respectively. CONCLUSION: TER for haemophilic elbow arthropathy provides good to excellent improvements in pain and elbow ROM postoperatively. However, the overall complication and revision rates are relatively high, when compared to TER performed for other indications.

Redeployment of the trainee orthopaedic surgeon during COVID-19: a fish out of water?

Background and purpose - COVID-19 has had a significant impact on health services and the entire healthcare sector, including trauma and orthopaedics, has been compelled to adapt. At the heart of this was the redeployment of the orthopaedic trainees to support "frontline specialties". This paper sheds light on the experience of orthopaedic trainees in redeployment. Methods - In this retrospective study, we asked orthopaedic trainees in the KSS (Kent, Surrey, Sussex) and London Deaneries to complete a survey regarding their experience in redeployment during the COVID-19 outbreak. The study took place in the Kent, Surrey, Sussex, and London regions of the United Kingdom over a period of 8 weeks from 15th of March 2020 until 15th of May 2020. The study was based at East Kent Hospitals University NHS Foundation Trust and participants were recruited from a number of secondary and tertiary care centres across the region. 120 orthopaedic trainees were contacted, working in 21 teaching hospitals. Of these, 40 trainees (30%) from 13 hospitals responded and completed the survey. Results - 50% of the surveyed trainees were redeployed to other specialties. Trainees spent varying amounts of time in the redeployed speciality and gave differing views on how comfortable they felt and how useful they felt the experience was. One-third of trainees experienced symptoms and/or tested positive for COVID-19 and the majority of these were redeployed to other specialties. Interpretation - Orthopaedic training appears to have taken a temporary back seat at this time but trainees have made a significant contribution to reinforcing key front-line specialties in the fight against COVID-19.

Reverse shoulder arthroplasty with a cementless short metaphyseal humeral prosthesis without a stem: survivorship, early to mid-term clinical and radiological outcomes in a prospective study from an independent centre.

INTRODUCTION: The use of reverse total shoulder arthroplasty has increased for the management of cuff-deficient glenohumeral joint arthritis and fractures. With bone preservation being a major target in reverse shoulder arthroplasty, metaphyseal humeral components without a stem were developed. The aim of this study is to present the survivorship, functional and radiological outcomes of a novel short metaphyseal prosthesis without a diaphyseal stem from an independent centre. METHODS: Clinical function and radiological features of patients undergoing stemless reverse shoulder arthroplasty were prospectively recorded. Patients' demographics, indications for surgery, complications, functional and radiological assessment at the final follow-up as well as survivorship with the end point of revision for any reason were recorded. RESULTS: Between 2009 and 2016, 36 patients received 37 reverse shoulder arthroplasties with the stemless Verso prosthesis. Mean age of the patients was 76.9 years. The most common indication for surgery was cuff tear arthropathy. Mean follow-up was 3 years (range 1-7 years). Oxford shoulder score improved from an average of 11 pre-operatively (range 2-19) to 44 post-operatively (range 29-48) (p < 0.0001). There was one case of a deep post-operative infection that needed washout, liner exchange with retention of the prosthesis. Radiographic analysis showed no lucencies, or stress shielding around the humeral or glenoid components. Constant score at the final follow-up was on average 63 (range 35-86). Activities of daily living with requirement for internal and external rotation score (ADLEIR) was on average 12 pre-operatively (range 0-27) and 31 post-operatively (range 18-36) (p < 0.0001). There was 100% survivorship of the prosthesis in this early to mid-term study. CONCLUSION: This early to mid-term prospective study demonstrates excellent survivorship and radiological results of the Verso reverse shoulder replacement. It needs a simple reproducible technique, and the results have been replicated at an independent centre. This study underlines its survivorship in the early to mid-term and confirms lower incidence of complications such as instability, notching, loosening and the need for revision surgery. Most importantly, it conserves the humeral bone stock for revision arthroplasties in the future. Our results are similar to those of the currently published literature.

Postoperative outcomes of third-generation shoulder hemiarthroplasties for three-and four-part proximal humeral fractures: A systematic review of published studies from 2012 to 2022.

Background: The aim of this study was to provide up-to-date evidence on the outcomes for hemiarthroplasties (HAs) that were performed using modern third-generation prostheses (post-2004) for isolated (excluding head-splits and fracture-dislocations) three-and four-part proximal humerus fractures (PHFs). Methods: PubMed, Medline, Embase and the Cochrane register were searched from January 1, 2012, to November 15, 2022, conforming to the PRISMA guidelines. The outcome measures were the complication rates, revision rates, surgery-related postoperative mortality, post-operative clinical outcome scores and radiological outcomes. Results: 432 hemiarthroplasties in 432 patients were performed across the 11 eligible studies (two prospective and 9 retrospective). Three studies compared HA versus reverse shoulder replacement (RSR); one study compared HA with locking plate fixation (LPF) and RSR; one study compared HA with LPF. 61.1 % and 19.4 % of hemiarthroplasties were performed using cemented and uncemented techniques respectively, while cementing data was ill-defined in 19.4 % of shoulders. The results for the outcome measures have been derived directly from the included studies and no statistical pooling was performed, due to heterogeneity in the different study designs and outcomes. Descriptive data synthesis from the included studies showed that third generation HAs have higher overall postoperative complication rates, with similar revision and mortality rates when compared to RSR and LPF for three-and four-part PHFs. RSR and LPF showed better statistically significant improvements than HA for the Constant-Murley score, Quick DASH, forward flexion and abduction. Mixed results were observed for the DASH score, ASES score and internal rotation ROM between RSR/LPF versus HA. Conclusion: Low to moderate quality evidence from this review showed that even third-generation HA prostheses provided worse overall outcomes than RSR and LPF for three-and four-part PHFs.

A Novel "Shark-Fin" Pyramidal Achilles Bone-Tendon Allograft Surgical Technique for Delayed Reconstruction of Triceps Tendon Rupture and Review of the Literature.

Purpose: Triceps tendon injuries are rare and often caused by direct trauma to the arm. There are no clear guidelines on the management of these and typically partial tears are treated conservatively whilst full thickness tears are treated with primary surgical repair. We aim to review the literature on the methods for triceps repair and propose a novel surgical technique. Methods: A "Medline" and "Embase" literature search of titles and abstracts combining "triceps brachii muscle," "reconstruct/ed" or "reconstruction" alongside "reconstructive surgical procedures," and further cross referenced with "repair/s/ed." Excluded those related to brachial plexus injuries or general elbow trauma and removing duplicate results. 32 English results within 10 years were relevant and reviewed. Results: A 50-year-old gentleman with a 4-month-old full thickness triceps tear was repaired with a novel surgical technique of using an Achilles bone-tendon allograft fashioned into a "shark-fin" pyramidal shape and secured to the proximal ulnar in a lock and key type construct. The tendon was secured to the triceps remnant using a Krackow stitch. Complete radiological and clinical recovery was made by 18 months postoperatively with return to full physical activity.The literature review concluded no consensus in the method of treatment for delayed triceps reconstruction. Conclusion: The use of the bone-tendon allograft specifically shaped to fit congruently into an olecranon osteotomy site allows for direct bone-to-bone healing has not previously been mentioned in the literature. Results have been encouraging and the technique described is easily reproducible.

Intermediate to long term results of stemless metaphyseal reverse shoulder arthroplasty: A five to nine year follow-up.

BACKGROUND: Shoulder arthroplasty incidence is increasing as is the volume of revision surgeries. Revision surgery is easier if humeral bone stock is preserved with minimal bone defects and osteolysis. This has led to an increased focus on the development of various short stemmed and stemless implants which provides stable fixation whilst preserving humeral bone stock. PURPOSE: To review the medium to long term clinical and radiological outcomes, complications and survival rates of a stemless reverse shoulder prosthesis. PATIENTS AND METHOD: Patients with a minimum follow-up of 60 months following a reverse stemless shoulder arthroplasty were deemed eligible. Clinical and radiological data on twenty-one patients operated between 2009 and 2014 were recorded prospectively. Survivorship and patient recorded symptoms with the end point of revision surgery were recorded. RESULTS: Mean follow-up of 78 months (60-114 months). Mean range of active elevation was 136° (80-170°). Mean range of active abduction and active external rotation was 122° (70-170°) and 47° (10-75°) respectively. Mean Oxford score improved from 12 pre-operatively to 44 at final follow up (p < 0.0001). Mean Constant Murley Score improved from 18 to 72 (p < 0.0001). Mean ADLEIR score of 13 pre-operatively increased to 32 post-operatively (p < 0.0001). Notching was seen in 23.5% of cases and no radiolucent areas were observed around the glenoid component. There were two cases of post traumatic peri-prosthetic fractures that were managed conservatively and one case of deep-seated infection that required a washout. The survivorship at the most recent follow-up was 100%. CONCLUSION: The advantages of bone preservation with the stemless metaphyseal prosthesis combined with encouraging medium to long term clinical and radiological results are very promising, particularly with the improved post-operative patient satisfaction scores. This is the first study that reports the results with a minimum of 5 year follow-up and has the longest mean follow-up period. CLINICAL RELEVANCE: The reverse stemless shoulder prosthesis is an effective and reliable option for elective shoulder arthroplasty.

Spontaneous displacement of olecranon fracture through geode salvaged by elbow replacement.

We present a case of pathological fracture of olecranon through a giant geode. Fracture was initially undisplaced and was treated conservatively. It later progressed to a transolecranon dislocation as a result of a pseudarthrosis at the fracture site. The patient presented 4 years later when she developed symptoms of ulnar nerve palsy. She was treated by a total elbow arthroplasty with ulnar nerve transposition. The current report highlights this unusual case and reviews the relevant literature.

Use of reverse stemless shoulder arthroplasty in a patient with multiple hereditary exostosis.

INTRODUCTION: Multiple hereditary exostosis (MHE) is the formation of benign, cartilage-capped bony outgrowths predominantly extending from the metaphysis of long bones that presents with reduction in growth, deformity, restricted motion, short stature and premature osteoarthritis. AIM: To review the clinical and radiological results of a stemless reverse shoulder arthroplasty in a case of MHE. CASE: 81-year-old, right hand dominant short-statured retired male engineer with long standing shoulder pain and restricted movements on the background of an old proximal humeral fracture managed conservatively.The radiographs revealed osteoarthritis and a mal-united proximal humerus fracture on the background of MHE with 3 plane bone deformity and a lack of medullary canal. RESULTS: The patient underwent a stemless reverse shoulder arthroplasty. At 6 months post operatively the patient had recovered well with a range of movement including: forward flexion 110°, external rotation 20° and abduction of 80°. Internal rotation remained limited to buttocks. Improved ADLIER, Subjective shoulder value and Constant Murley score compared to pre-operative figures. CONCLUSION: The stemless humeral component relies on metaphyseal impaction for stability. When the humeral canal is malformed or in presence of malunited distal fractures, it circumvents the need of navigating a deformed diaphysis with encouraging postoperative results.

The active elevation lag sign and the triangle sign: new clinical signs of trapezius palsy.

BACKGROUND: Spinal accessory nerve palsy causing trapezius dysfunction can lead to significant disability. Diagnosis is frequently delayed or inaccurate leading to inappropriate treatment. METHODS: We describe new clinical signs for trapezius muscle dysfunction and palsy, and accessory nerve palsy, viz. The Active Elevation Lag sign and the Triangle sign. These signs help to differentiate between scapular winging due to trapezius dysfunction and that due to serratus anterior dysfunction. The signs are based on the principle that the deficiency of trapezius function causes an ;active forward elevation lag' with compensatory spinal hyperextension, and lead to the Triangle sign in the prone position, whereas no such lag is found in patients with pure serratus anterior dysfunction. Video recordings of clinical examination of 10 patients, 5 with isolated spinal accessory nerve palsy and 5 with long thoracic nerve palsy (confirmed by neurophysiology studies) were blinded and reviewed by 8 assessors. RESULTS: Of the total of 80 readings, 100% sensitivity and 95% specificity were found, in correlation with the diagnosis confirmed by neurophysiology studies, with positive predictive value of 95% and negative predictive value of 100%. CONCLUSION: These are simple clinical signs, easy to perform which are useful in diagnosing trapezius weakness in clinical practice. LEVEL OF EVIDENCE: Level 2-1; Evidence obtained from well-designed controlled trials without randomization.

Ilizarov ring fixator for a difficult case of ankle syndesmosis disruption.

Syndesmotic stabilization is recommended for tibiofibular diastasis, a Maisonneuve fracture, or syndesmotic instability after fixation of distal tibia-fibula fractures. In the case presented, a syndesmotic stabilization was performed with a screw inserted 2 cm above the tibiotalar joint Subsequent failure occurred due to the weight of the patient and a lack of compliance with the necessary nonweight bearing protocol. The Ilizarov frame was used to reduce and maintain a stable syndesmosis with a simple two-ring construct which allowed the patient to bear weight on the injured limb while his syndesmosis healed. This is not recommend as a routine method of treatment, but is presented as an extended indication of the Ilizarov frame for difficult cases.
