Meta-analysis of open reduction and internal fixation versus total elbow arthroplasty for distal humeral fracture in the elderly / 中国组织工程研究

BACKGROUND: The most common surgical procedure for the treatment of distal humeral fracture in the elderly is open reduction and internal fixation and total elbow arthroplasty. There is still a lack of systematic evaluation of the efficacy between the two methods, and further research is needed to better guide clinical work. OBJECTIVE: To compare the clinical efficacy of open reduction and internal fixation combined with total elbow arthroplasty in the treatment of elderly patients with distal humeral fractures. METHODS: The computer was used to retrieve information in databases such as PubMed, The Cochrane Library, EMBASE, Science Direct, CNKI, Wanfang, and VIP. An observational cohort study or randomized controlled trial was performed in the study of open reduction and internal fixation/total elbow arthroplasty for the treatment of elderly patients with distal humeral fractures. The search period was 1998-2018. Studies were read and screened; data were extracted and the quality of the study was assessed by two persons independently. Data analysis was performed using RevMan 5.3. RESULTS AND CONCLUSION: (1) A total of 10 studies were included in 1 069 patients. (2) Meta-analysis results showed that total elbow arthroplasty group was superior to the open reduction and internal fixation group in the incidence of total complications (OR=1.67, 95%C/: 1.19-2.35, P=0.003), Mayo elbow performance score at the last follow-up (MD=-12.68, 95%C/: -16.60 to -8.77, P 0.05). (4) These results confirmed that the total complication rate of the total elbow arthroplasty group was lower than that of the open reduction and internal fixation group, and the elbow joint function was better than that of the open reduction and internal fixation group. For elderly patients with distal humeral fracture, the degree of osteoporosis is different, and the articular surface is difficult to be effectively reset. The treatment of total elbow arthroplasty should be considered.

Effectiveness of total elbow arthroplasty with preservation of triceps brachii insertion approach / 中国修复重建外科杂志

Objective: To investigate the effectiveness of total elbow arthroplasty (TEA) with preservation of triceps brachii insertion approach. Methods: Between January 2012 and September 2017, 17 patients with elbow disease were treated with TEA with preservation of triceps brachii insertion approach. There were 3 males and 14 females, with an average age of 65.2 years (range, 48-85 years). The injuries located on left elbow in 5 cases and on right elbow in 12 cases. There were 11 cases of distal humerus fracture (AO type C1 in 2 cases and type C3 in 9 cases); the interval between fracture and operation was 3-10 days (mean, 4.1 days). There were 3 cases of osteoarthritis and 3 cases of rheumatoid arthritis, with the disease duration of 2-26 years (mean, 8.7 years). The postoperative elbow function and pain was assessed by Mayo elbow performance score (MEPS) and visual analogue scale (VAS) score, respectively. The prosthesis position, heterotopic ossification, and periprosthetic fracture were observed by X-ray films. Results: All incisions healed by first intention. Sixteen patients were followed up 18-69 months (mean, 40.6 months). Intraoperative ulnar nerve injury occurred in 2 cases, and healed after symptomatic treatment. At last follow-up, the MEPS score was 55-100 (mean, 90.3). The results were excellent in 11 cases, good in 2 cases, fair in 2 cases, and poor in 1 case, with an excellent and good rate of 81.3%. The VAS score was 0-2 (mean, 0.4). X-ray reexamination showed that no polyethylene wear, prosthesis loosening and fracture, abnormal prosthesis position, periprosthetic fracture occurred during the follow-up period, and the prosthesis survival rate was 100%. Heterotopic ossification occurred in 2 and 3 months after operation in 2 cases, respectively. Conclusion: The triceps on approach for TEA are satisfactory for distal humerus fracture, osteoarthritis, and rheumatoid arthritis.

Artroplastía total de codo para el tratamiento de fracturas de húmero distal en pacientes mayores de 65 años / Total elbow arthroplasty for distal humerus fractures in patients older than 65 years old

Objetivo: Comunicar los resultados clínico-radiológicos del tratamiento de las fracturas de húmero distal con prótesis total de codo en pacientes >65 años. Materiales y Métodos: Estudio retrospectivo en dos centros quirúrgicos. Criterios de inclusión: pacientes con fractura de húmero distal, >65 años, operados con prótesis total de Coonrad-Morrey y seguimiento >1 año. Se incluyeron 21 pacientes (20 mujeres), edad promedio: 79 años. Según la clasificación AO, 13 C3, siete C2 y una A2. Todos fueron operados sin desinserción del aparato extensor. Seguimiento promedio: 40 meses. Resultados: La flexo-extensión fue de 123-17°, arco de movilidad de 106° (80% con respecto al lado sano). Dolor según la escala analógica visual: 1 punto. El puntaje de la Clínica Mayo promedio fue 83: resultado excelente (8 pacientes), bueno (11 pacientes), regular (1 caso) y malo (1 caso). El puntaje DASH promedio fue de 24. No hubo aflojamientos en 13 pacientes. Se produjeron nueve complicaciones: dos pacientes fueron operados nuevamente por desgaste del polietileno, uno operado otra vez al mes de la cirugía para la recolocación del perno de ensamble, dos parestesias del nervio cubital, una falsa vía intraoperatoria, un hematoma de la herida que necesitó de un colgajo braquial y dos aflojamientos protésicos. Conclusiones: El tratamiento de las fracturas de húmero distal con prótesis total de codo en pacientes >65 años puede ofrecer una opción terapéutica razonable, pero las indicaciones deben limitarse a fracturas complejas donde la fijación interna puede ser precaria, en pacientes con osteoporosis y con baja demanda funcional.

Objective: To report the clinical-functional results of humeral distal fracture treatment with total elbow prosthesis in patients older than 65 years. Methods: Retrospective study performed in two surgical centers. Inclusion criteria: patients with humeral distal fractures, >65 years, operated on with Coonrad-Morrey prostheses, and with a follow-up >1 year. Twenty-one patients were included (20 women) with an average age of 79 years. According to AO classification: 13 type C3 fractures, 7 C2 and 1 A2. All patients were operated on without disinsertion of the extensor mechanism. Average follow-up: 40 months. Results: Flexion-extension: 123-17°, with a total arc of mobility of 106° (80% of the contralateral side). Pain according to visual analogue scale was 1. The Mayo Clinic score was 83 points, results were excellent (8 patients), good (11 patients), regular (one case) and bad (one case). Average DASH score was 24 points. No loosening of the implants was evidenced in 13 patients. Nine complications were reported: 2 reoperations for polyethylene wear, one early decoupling of the prosthesis, 2 ulnar nerve paresthesia, one patient presented a false intraoperative via, one hematoma that needed a local flap and 2 loosening of the prosthesis. Conclusions: Treatment of humeral distal fractures with total elbow arthroplasty in patients older than 65 years may be a good therapeutic option, but indications must be limited to patients with complex fractures, bad bone quality, with osteoporosis and low functional demands.

Extended Kocher Approach for Total Elbow Arthroplasty

PURPOSE: Total elbow arthroplasty is most commonly performed through a posterior approach by splitting or reflecting the triceps off the olecranon, but triceps avulsion, triceps weakness, and wound healing problems have been reported. We present the clinical results of total elbow arthroplasty using extended Kocher approach. MATERIALS AND METHODS: From September 2005 to October 2007, five patients who underwent total elbow arthroplasty using triceps preserving approach were evaluated. There were 4 women and 1 man. The mean age of the patients was 58 years (range, 36~68). The mean follow- up was 10 months. The patients were placed in the lateral decubitus position, and lateral Kocher interval is made through a straight posterior incision. Elbow joint is exposed by supinating the forearm and prosthesis was inserted. Postoperatively, the elbow was immobilized in extension for 1 week, and active range of motion exercise was begun. Range of motion, triceps strength, Mayo elbow performance score, Korean DASH questionnaire were evaluated at the last follow-up. RESULTS: Average operation time was 115 minutes (range, 97~138). Postoperative complications such infection, skin necrosis were not developed. Triceps strength was measured as grade IV in all patients except one who has triceps insufficiency preoperatively. Mean elbow range of motion was from 8 degrees to 124 degrees. Mean Mayo elbow performance score was 87 (range 75~95), and DASH score was 18 (range 9~34). CONCLUSIONS: Extended Kocher approach can be a reasonable alternative for total elbow arthroplasty. Linking the assembly can be difficult, so modification of the implant design is needed to solve this problem.

A Novel Autogenous Iliac Bone Graft Technique for Distal Humeral Bone Loss in Revisional Total Elbow Arthroplasty: A Technical Note / 대한정형외과학회잡지

As the incidence of total elbow arthroplasty has increased, revisions of the procedure also increase including reconstruction of bony defects caused by bone destruction. Reconstruction techniques depend on location and severity of the bony defect, and allografts are useful in cases of substantial bone loss. However, this procedure is technically difficult and has a high complication rate. Here, we describe a novel autogenous bone graft technique using tricortical iliac bone for reconstruction of a distal bone loss in a revisional total elbow arthroplasty, providing an additional method to restore bone stock.

Total Elbow Arthroplasty after Failed Surgical Treatment for Elbow Fracture or Dislocation

PURPOSE: The current study reports the clinical results of total elbow arthroplasties (TEA) which were Performed on patients with poor clinical and radiological results after initial surgeries for elbow fractures or dislocations. MATERIALS AND METHODS: The clinical outcomes of twelve consecutive patients who underwent TEA after failed surgeries for elbow fractures or dislocations from january, 1995 to December, 2005 were evaluated. The initial diagnoses were distal humeral fractures in 8 cases and fracture-dislocations in 4 cases. The Mean period from the initial operations to the TEAs was 12 months. The mean folloow up period after TEA was 43 months. RESULTS: The mean range of motion, in terms of active extension, activeflexion, supination, and pronation, improved from 14.2degrees, 96.7degrees, 50.8degrees and 53.3degrees to 5.4degrees, 122.1degrees, 63.3degrees and 67.5degrees, respectively (p<0.05).RAdiolucent lines were found in 3 cases, which were 1 case of type 3, and 2 cases of type 4. All three loosening cases underwent revision TEAs. The mean postoperative Mayo elvow performance score was 79 point. There were 6 cases of excellent, 2 cases of good, and 4 cases in poor. CONCLUSION: Good clinical results were obtained after TEA performed in failed surgeries for elbow fractures of dislocations.

Total Elbow Arthroplasty for the Fracture of Elbow Arthrodesis Site: A Case Report

Total elbow arthroplasty is a relatively rare procedure compared with total knee or total hip arthroplasty. Total elbow arthroplasty for bony ankylosis is even rarer, and the results are often unsatisfactory. We report a patient who gained good mobility of the elbow after total elbow arthroplasty for the treatment of fractured arthrodesis site with which the patient had lived with for 12 years.

Clinical Outcomes of Semiconstrained Total Elbow Arthroplasty : Non-traumatic Arthritisversus Traumatic Arthritis / 대한정형외과학회잡지

PURPOSE: This study evaluated the clinical and radiological outcomes of semiconstrained total elbow arthroplasty. MATERIALS AND METHODS: Thirty-nine elbows with semiconstrained total elbow arthroplasty and who were followed up for at least 3 years were enrolled in this study. There were 29 and 10 cases in the non-traumatic arthritis and traumatic arthritis groups, respectively. The mean age at the time of surgery was 53.9 years, and the mean follow-up period was 54 months. RESULTS: At the last follow-up, the pain score during motion decreased from 7.37 to 1.23. The Mayo elbow performance score was 86. The mean loss of terminal extension improved from 32degrees to 11degrees and the mean maximum flexion improved from 90.3degrees to 125.2degrees. Radiology analysis, 15 elbows showed radiolucency and 8 elbows showed loosening. There were 13 cases of radiolucency and 7 cases of loosening in the non-traumatic arthritis group. In the traumatic arthritis group, there were 2 cases of radiolucency and 1 case of loosening. CONCLUSION: Semiconstrained total elbow arthroplasty for non-traumatic and traumatic arthritis of the elbow produced satisfactory functional results. The non-traumatic arthritis group had a higher incidence of radiolucency and loosening than the traumatic group.
