Telemedicine in orthopaedics and trauma surgery during the first year of COVID pandemic: a systematic review.

PURPOSE: Prior to the COVID-19 pandemic, telemedicine in orthopaedics and trauma surgery had mostly developed for joint arthroplasty, fracture management, and general pre- and postoperative care including teleradiology. With the corona-outbreak, telemedicine was applied on a broad scale to prevent assemblage and to guarantee access to medical care protecting critical areas. The purpose of the present study was to give an overview of the spectrum of clinical applications and the efficacy of telemedicine in orthopaedic and trauma surgery as published in times of the COVID-19 pandemic. METHODS: All published studies investigating the application of telemedicine related to orthopaedics and trauma during the COVID-19 pandemic were accessed and screened for suitability. The primary outcome of interest was the efficacy of telemedicine in various clinical applications. The secondary outcome of interest was the spectrum of different applications in which telemedicine applications were investigated. RESULTS: The literature search resulted in 1047 articles. After the removal of duplicates, 894 articles were screened of which 31 finally met the inclusion criteria. Dimensions that were described by studies in the literature to have positive effects were preoperative patient optimisation, the usefulness of telemedicine to correctly diagnose a condition, conservative treatment, willingness to and feasibility for telemedicine in patients and doctors, and postoperative/post-trauma care improvement. The efficacy of telemedicine applications or interventions thereby strongly varied and seemed to depend on the exact study design and the research question addressed. CONCLUSION: Various successful applications of telemedicine have already been reported in orthopaedics and trauma surgery, with a strong increase in scientific output during the COVID-19 years 2020-2021. Whether the advantages of such an approach will lead to a relevant implementation of telemedicine in everyday clinical practice should be monitored after the COVID-19 pandemic.

Patient outcomes and return to play after arthroscopic rotator cuff repair in overhead athletes: a systematic review.

BACKGROUND: Rotator cuff tear injuries in overhead athletes are common and may lead to chronic pain and joint disability, impairing sport participation and leading to premature retirement. The improvement of the patient reported outcome measures (PROMs) was evaluated, as were the time and level of return to sport and the rate of complication in overhead athletes who had undergone arthroscopic rotator cuff repair. METHODS: This systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses: the 2020 PRISMA statement. In September 2022, the following databases were accessed: Pubmed, Web of Science, Google Scholar and Embase. No time constraints were used for the search. All the clinical trials investigating arthroscopic rotator cuff repair in overhead athletes were accessed. RESULTS: Data from 20 studies were collected. The mean length of the follow-up was 40 months. All PROMs improved at last follow-up: Kerlan-Jobe Orthopaedic Clinic score (P = 0.02), visual analogue scale (P = 0.003), Constant score (P < 0.0001), University of California Los Angeles Shoulder score (P = 0.006) and American Shoulder and Elbow Surgeons' score (P < 0.0001). Elevation also improved (P = 0.004). No difference was found in external and internal rotation (P = 0.2 and P = 0.3, respectively). In total, 75.4% (522 of 692 of patients) were able to return to play within a mean of 6.4 ± 6.0 months. Of 692 patients, 433 (62.5%) were able to return to sport at pre-injury level. Fourteen out of 138 patients (10.1%) underwent a further reoperation. The overall rate of complications was 7.1% (20 of 280). CONCLUSION: Arthroscopic reconstruction of the rotator cuff is effective in improving function of the shoulder in overhead athletes, with a rate of return to sport in 75.4% of patients within an average of 6.4 months. LEVEL OF EVIDENCE: III, systematic review. TRIAL REGISTRATION: Not applicable.

Platelet-rich plasma (PRP) augmentation does not result in more favourable outcomes in arthroscopic meniscal repair: a meta-analysis.

BACKGROUND: The efficacy and safety of platelet-rich plasma (PRP) augmentation for arthroscopic meniscal repair is controversial. This meta-analysis compared arthroscopic meniscal repair performed in isolation or augmented with PRP. METHODS: The present study was conducted according to PRISMA 2020 guidelines. Pubmed, Web of Science, Google Scholar and Embase were accessed in August 2021. All the clinical trials which compared arthroscopic meniscal repair performed in isolation or augmented with PRP were included. RESULTS: Eight hundred thirty-seven patients were included: 38% (318 of 837 patients) were women; the mean age of the patients was 35.6 (range, 20.8-64.3) years; the mean follow-up was 26.2 (range, 6-54) months. Similarity was found in analogue scale (VAS) (P = 0.5) and Lysholm (P = 0.9), and International Knee Documentation Committee (IKDC) scores (P = 0.9). Similarity was found in the rate of failure (P = 0.4) and rate of revision (P = 0.07). CONCLUSION: The current published scientific evidence does not support PRP augmentation for arthroscopic meniscal repair.

Selective versus non-selective NSAIDs as prophylaxis for heterotopic ossification following hip arthroplasty: a meta-analysis.

BACKGROUND: Some patients have demonstrated evidence of heterotopic ossification (HO) following total hip arthroplasty (THA). Selective and non-selective non-steroidal anti-inflammatory drugs (NSAIDs) are used as prophylaxis for HO following THA. This meta-analysis compared selective versus non-selective NSAIDs as prophylaxis for HO following THA. MATERIAL AND METHODS: The present study was conducted according to the PRISMA 2020 guidelines. All the clinical investigations comparing selective versus non-selective NSAIDs as prophylaxis for HO following THA were accessed in February 2022. An assessment of the methodological quality and statistical analyses were performed through the risk of bias summary tool of the Review Manager 5.3 software (Cochrane Collaboration, Copenhagen). The modified Brooker staging system was used to rate the efficacies of the interventions. RESULTS: Data from 8 studies and 1526 patients were collected. 60.8% were female. No difference was found in the sample size, mean age, and percentage of females between the two groups at baseline. No statistically significant difference was found between selective and non-selective NSAIDs in term of efficacy. 72% (1078 of 1502) of the patients were classified as Brooker 0, 21% (322 of 1502) as Brooker I, 5% (80 of 1502) as Brooker II, 1% (16 of 1502) as Brooker III, and 0.1% (2 of 1502) as Brooker IV. CONCLUSION: Selective and non-selective NSAIDs were equally effective when used as prophylaxis for HO following THA. LEVEL OF EVIDENCE: Level III, systematic review and meta-analysis.

[Posttraumatic deformity of the thoracolumbar spine]. / Posttraumatische Fehlstellungen der Brust- und Lendenwirbelsäule.

Posttraumatic kyphotic deformities of the thoracolumbar spine may result in significant clinical complaints. If conservative treatment is not successful, surgical correction of the kyphosis becomes an option. In contrast to degenerative deformities, posttraumatic kyphotic deformities are usual limited to few segments and can be treated with shorter constructs. The surgical strategy depends on the rigidity and the localization of the posttraumatic kyphotic deformity. In this respect purely posterior approaches and combined posteroanterior surgical approaches are available each with different advantages and disadvantages.

[Treatment of proximal femoral fractures : Principles, tips and tricks]. / Therapie proximaler Femurfrakturen : Grundlagen, Tipps und Tricks.

Proximal femoral fractures occur at an annual incidence of approximately 200/100,000 inhabitants and mortality rates range up to 30% especially in geriatric patients where complications are not necessarily associated to surgery. In nearly all cases surgical treatment is required. Procedures to preserve the femoral head have to be performed as early as possible (as specified by the Federal Joint Committee, GBA, within 24 h). For joint-preserving approaches in medial femoral neck fractures a time to surgery within 6 h is considered to be advantageous. Perioperative patient care is of high importance regarding the prevention of pneumonia, renal failure, delirium and further complications. Postoperatively full weight bearing enables for early mobilization and prevention of surgery-related complications. Nonunions, avascular necrosis of the femoral head, cut-out and prosthetic dislocation must be avoided by the selection of the appropriate procedure. Minimally displaced femoral neck fractures are primarily treated by osteosynthesis and conservative management is only considered in isolated cases. For displaced femoral neck fractures, factors such as a young biological age with high activity levels, the absence of arthritis and good bone quality with a successful reduction favor for a femoral head-preserving osteosynthesis. Otherwise, (hybrid) total hip replacement (THR) is the preferred method for unstable and displaced fractures, whereby hemiarthroplasty should only be considered for very old and patients with pre-existing diseases. Fractures in the trochanteric region are treated with a proximal femoral nail and subtrochanteric fractures are managed using a long proximal femoral nail. To avoid secondary complications, the choice of optimal treatment should be based on a good understanding of the injury pattern, biomechanical and technical aspects of each procedure.

European society for trauma and emergency surgery member-identified research priorities in emergency surgery: a roadmap for future clinical research opportunities.

BACKGROUND: European Society for Trauma and Emergency Surgery (ESTES) is the European community of clinicians providing care to the injured and critically ill surgical patient. ESTES has several interlinked missions - (1) the promotion of optimal emergency surgical care through networked advocacy, (2) promulgation of relevant clinical cognitive and technical skills, and (3) the advancement of scientific inquiry that closes knowledge gaps, iteratively improves upon surgical and perioperative practice, and guides decision-making rooted in scientific evidence. Faced with multitudinous opportunities for clinical research, ESTES undertook an exercise to determine member priorities for surgical research in the short-to-medium term; these research priorities were presented to a panel of experts to inform a 'road map' narrative review which anchored these research priorities in the contemporary surgical literature. METHODS: Individual ESTES members in active emergency surgery practice were polled as a representative sample of end-users and were asked to rank potential areas of future research according to their personal perceptions of priority. Using the modified eDelphi method, an invited panel of ESTES-associated experts in academic emergency surgery then crafted a narrative review highlighting potential research priorities for the Society. RESULTS: Seventy-two responding ESTES members from 23 countries provided feedback to guide the modified eDelphi expert consensus narrative review. Experts then crafted evidence-based mini-reviews highlighting knowledge gaps and areas of interest for future clinical research in emergency surgery: timing of surgery, inter-hospital transfer, diagnostic imaging in emergency surgery, the role of minimally-invasive surgical techniques and Enhanced Recovery After Surgery (ERAS) protocols, patient-reported outcome measures, risk-stratification methods, disparities in access to care, geriatric outcomes, data registry and snapshot audit evaluations, emerging technologies interrogation, and the delivery and benchmarking of emergency surgical training. CONCLUSIONS: This manuscript presents the priorities for future clinical research in academic emergency surgery as determined by a sample of the membership of ESTES. While the precise basis for prioritization was not evident, it may be anchored in disease prevalence, controversy around aspects of current patient care, or indeed the identification of a knowledge gap. These expert-crafted evidence-based mini-reviews provide useful insights that may guide the direction of future academic emergency surgery research efforts.

Efficacy of ibuprofen and indomethacin as prophylaxis of heterotopic ossification: a comparative study.

The prophylactic action of non-steroidal anti-inflammatory drugs (NSAIDs) in heterotopic ossification (HO) was first described following analgesic therapy with indomethacin. Following that evidence, several compounds have been successfully used for prophylaxes of HO. Ibuprofen has been also proposed for the prevention of HO following THA. The present study compared the administration of ibuprofen for three weeks versus indomethacin as prophylaxis for HO following primary THA. In all THA procedures, pre- and post-operative protocols were conducted in a highly standardized fashion. The type of HO prophylaxis (indomethacin 100 mg/daily or ibuprofen 100 mg/daily) was chosen according to a chronological criterion: from 2017 to 2019 indomethacin was used, whereas from 2019 to 2022 ibuprofen was administered. In case of allergy or intolerance to NSAIDs, no prophylaxis was performed, and patients were included as a control group. All patients who underwent an anteroposterior radiography of the pelvis at a minimum of 12 months following THA were considered for inclusion. On admission, the age and sex of the patients were recorded. Moreover, the causes of osteoarthritis and the date of surgery were recorded. The grade of HO was assigned by a blinded assessor who was not involved in the clinical management of the patients. The modified Brooker Staging System was used to rate the efficacy of the interventions. Data from 1248 patients were collected. 62% (767 of 1248 patients) were women. The mean age was 67.0 ± 2.9 years. The mean follow-up was 21.1 ± 10.8 months. In the ibuprofen group, 73% of patients evidenced Brooker 0, 17% Brooker I, and 10% Brooker II. In the indomethacin group, 77% of patients evidenced Brooker 0, 16% Brooker I, 6% Brooker II. No patient in the ibuprofen and indomethacin group developed Brooker III or IV. In the control group, 64% of patients evidenced Brooker 0, 21% Brooker I, 3% Brooker II, and 12% Brooker III. No patient in the control group developed Brooker IV HO. Concluding, three weeks of administration of ibuprofen demonstrated similar efficacy to indomethacin in preventing HO following primary THA. The prophylaxis with ibuprofen or indomethacin was more effective in preventing HO compared to a control group who did not receive any pharmacological prophylaxis.

Single versus double bundle in posterior cruciate ligament (PCL) reconstruction: a meta-analysis.

Posterior cruciate ligament (PCL) reconstruction can be performed using single bundle (SB) and double bundle (DB) techniques. The present study investigated whether DB PCL reconstruction is superior to SB reconstruction in terms of patient reported outcome measures (PROMs) and joint stability. In December 2021 Embase, Google Scholar, Pubmed, Scopus databases were accessed. All clinical trials comparing SB versus DB reconstruction to address PCL insufficiency in skeletally mature patients were considered. Data from 483 procedures were retrieved. The mean follow-up was 31.0 (28.0 to 107.6) months, and the mean timespan between injury and surgery was 11.3 (6 to 37) months. The mean age of the patients was 29.3 ± 3.8 years. 85 of 483 patients (18%) were women. At a mean of 31.0 months post reconstruction, ROM (P = 0.03) was slightly greater in the SB group, while the Tegner score (P = 0.03) and the Telos stress (P = 0.04) were more favorable in the DB cohort. Similarity was found in instrumental laxity (P = 0.4) and Lysholm score (P = 0.3). The current evidence does not support the use of DB techniques for PCL reconstruction. Both methods could restore knee stability and motion with satisfactory short term patient reported outcome measures. Further high quality clinical trials are required to validate these results on a larger scale.

Autologous matrix induced chondrogenesis (AMIC) as revision procedure for failed AMIC in recurrent symptomatic osteochondral defects of the talus.

Autologous matrix induced chondrogenesis (AMIC) is a bone marrow stimulating technique used for the surgical management of chondral defects of the talus. The present study evaluated the clinical outcomes and imaging of AMIC as revision procedure for failed AMIC surgery for osteochondral defects of the talus. Forty-eight patients with symptomatic osteochondral defects who received a revision AMIC were evaluated after a minimum of two years follow-up. Patients with previous procedures rather than AMIC, those who required additional surgical procedures (e.g. ligament repair or deformity correction), or those who had evidence of kissing, bilateral, or multiple lesions were excluded. Outcome parameters included the Visual Analogic Scale (VAS), Tegner Activity Scale, the American Orthopedic Foot and Ankle Score (AOFAS), and the Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) score. All patients were followed by an assessor who was not involved in the clinical management. 27 patients were enrolled in the present study. The mean age of the patient was 34.9 ± 3.1 years, and the mean BMI 27.2 ± 5.1 kg/m2. The mean defect surface area was 2.8 ± 1.9 cm2. The mean follow-up was 44.3 ± 21.4 months. The mean hospital length of stay was 4.4 ± 1.4 days. At final follow-up, the mean VAS score was 4.1 ± 3.1, the mean Tegner 3.5 ± 1.6, the mean AOFAS 58.8 ± 20.6. The preoperative MOCART score was 22.1 ± 13.7 points, the postoperative MOCART score was 42.3 ± 27.9 points (+ 20.2%; P = 0.04), respectively. 30% (8 of 27 patients) experienced persistent pain and underwent a further chondral procedure. Concluding, AMIC could be a viable option as revision procedure for failed AMIC in recurrent symptomatic osteochondral defects of the talus. The PROMs indicated that patients were moderately satisfied with the procedure, and the MOCART score demonstrated a significant improvement from baseline to the last follow-up. A deeper understanding in prognostic factors and patient selection is critical to prevent failures.

Chondral injuries in patients with recurrent patellar dislocation: a systematic review.

BACKGROUND: Patellar dislocations in patients presenting with recurrent patellofemoral instability can damage the surrounding structures, limiting patient's participation to recreational activities and quality of life. This study evaluated frequency, location, and extent of associated injuries in patients with recurrent patellar dislocation. METHODS: This systematic review was conducted according to the PRISMA checklist. PubMed, Google scholar, Embase, and Web of Science databases were accessed in July 2021. All the published clinical studies reporting frequency, location, and extent of soft tissue lesions in patients with recurrent patellar dislocations were accessed. RESULTS: Data from 9 articles (232 patients) were retrieved. The mean age of the included patients was 21.2 ± 5.6 years. 84.8% of patients suffering from recurrent patellar dislocations demonstrated patellar chondral defects: medial facet (34.9%), while patellar crest (34.8%) and lateral facet (17%). 27.8% of patients demonstrated trochlear chondral injuries. CONCLUSION: Chondral defects of the medial facet and the crest of the patella are the most common in patients with recurrent patellofemoral instability.

Factors influencing the outcomes of minimally invasive total hip arthroplasty: a systematic review.

INTRODUCTION: The present systematic review investigated possible factors which may influence the surgical outcome of minimally invasive surgery for total hip arthroplasty (MIS THA). METHODS: In January 2022, the Embase, Google Scholar, PubMed, and Scopus databases were accessed. All the clinical trials investigating the clinical outcome of MIS THA were considered. RESULTS: Data from 9486 procedures were collected. Older age was moderately associated with greater Visual Analogue Scale (VAS) (P = 0.02) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) (P = 0.009) at last follow-up, and shorter surgical duration (P = 0.01). Greater body mass index (BMI) at baseline was moderately associated with greater cup anteversion (P = 0.0009), Oxford Hip Score (OHS) at last follow-up (P = 0.04), longer surgical duration (P = 0.04), increased leg length discrepancy (P = 0.02), and greater rate of infection (P = 0.04). Greater VAS at baseline was weakly associated with greater VAS at last follow-up (P < 0.0001), total estimated blood lost (P = 0.01), and lower value of Harris Hip Score (HHS) (P = 0.0005). Greater OHS at baseline was associated with greater post-operative VAS (P = 0.01). Greater WOMAC at baseline was associated with lower cup anteversion (P = 0.009) and greater VAS (P = 0.02). Greater HHS at baseline was associated with shorter hospitalisation (P = 0.001). CONCLUSION: Older age and greater BMI may represent negative prognostic factors for MIS THA. The clinical outcome is strongly influenced by the preoperative status of patients.

Radiolunate fusion in the rheumatoid wrist via three point fixation with a mini-titanium-T-plate and oblique screw.

PURPOSE: Traditional surgical techniques for radiolunate arthrodesis typically result in an unsatisfactory primary stability. Thus cast immobilisation is implemented until bone healing is complete. Nonunion and implant dislocation are frequent complications. METHODS: Eighteen patients (20 wrists) with rheumatoid disease who had undergone a radiolunate arthrodesis procedure using a mini-titanium-T-plate with an oblique screw were examined. The high primary stability of this fusion depends on three point fixation. RESULTS: Complete bone healing was achieved in all wrists. Dislocation of a screw occurred in one wrist which subsequently healed in mild dislocation. Grip strength improved in 12 hands with pain relief in 19 wrists. 18 patients rated the result of the operation as "very good" or "good" and would agree to have the operation again. CONCLUSION: The mini-titanium-T-plate with oblique screw achieves high primary stability via three point fixation of the lunate at the radius. Thus, postoperative immobilisation in a cast is unnecessary. The procedure is well tolerated by patients with a high satisfaction rating.

External fixation in the elderly.

Orthopaedic trauma is an increasingly common problem in geriatric patients. As demands of daily life and recreational activities are increasing in these patients, surgeons need to be able to manage geriatric fractures to achieve good functional results. Reduced bone quality in the elderly presents a considerable challenge and may preclude the use of established surgical stabilisation techniques that are performed in younger trauma patients. Furthermore, pre-existing medical conditions and considerable comorbidities in the elderly could complicate standard surgical procedures that younger patients would be offered. In this respect, application of external fixators represents a validated, minimally-invasive treatment opportunity. This review article summarises the use of external fixation in geriatric trauma patients for wrist fractures, proximal femoral fractures, pelvic fractures, and ankle fractures. Modern modifications, like pin coating with hydroxyapatite, and aspects of pin care will be discussed.

Damage control: extremities.

The principles of fracture management in polytrauma patients continue to be of crucial importance. Over the last five decades, various strategies of fracture treatment in the multiply injured patient have evolved. The various new methodologies remain controversial. In the beginning, early surgical fracture treatment of long bone fractures after multiple trauma was not routinely advocated. It was believed that the polytraumatised patient did not have the physiological reserve to withstand prolonged operations. The introduction of standardised, definitive surgical protocols, led to the concept of early total care (ETC) in the 1980s. This concept was subsequently applied universally, in all patient groups, regardless of injury severity and distribution. Later, it became apparent that certain patients did not appear to benefit from ETC. Indeed, extended operative procedures, during the early phase of multiple trauma recovery, were associated with adverse outcome. This applied for patients with significant thoracic, abdominal and head injuries and those with high injury severity scores (ISS). In response, the concept of damage control orthopaedics (DCO) was developed in the 1990s. DCO methodology is characterised by primary, rapid, temporary fracture stabilization. Secondary definitive management follows, once the acute phase of systemic recovery has passed. We explore the processes underlying the systemic biological impact of fracture fixation, the evolution of operative treatment strategies for major fractures in polytrauma and the current trends toward staged management of these patients.
