Plate Analysis

This study evaluated triple arthrodesis at late follow-up using the liquid crystal force plate and standard clinical methods. Twenty-four patients with 36 triple arthrodeses were followed-up at an average of 8 ± 2 years. Fifty-eight per cent of patients achieved an ideal or good rating with 11% failures. Failures were due to inadequate surgical correction of varus deformity. Seven per cent of joints with roentgenographic degenerative changes had associated mild pain. Triple arthrodesis produced many deviations from normal load-bearing: 1) calcaneovalgus residuals produced symptomatic posterior heel force concentrations; 2) residual forefoot supination produced symptomatic force concentrations under the fifth metatarsal and toe; 3) residual forefoot pronation produced increased midfoot and medial metatarsal load-bearing, generally asymptomatic; and 3) a significant increase in midfoot weightbearing occurred in most triple arthrodesis patients.

SummaryObjective: Retrospective case series describing the surgical treatment and outcome in dogs with bicondylar femoral fractures complicated by ligament or tendon injuries.Methods: Medical records were reviewed for three immature and one mature dog with traumatic bicondylar fractures of the distal femur and concurrent ligament or tendon injury treated surgically. Data retrieved included physical examination, imaging, and treatment. Long-term follow-up and return to function was assessed by owner feedback, physical examination, radiology, and force plate analysis. The immediate, four-week, and two-year postoperative outcomes were described.Results: All four dogs were presented with injuries to either the cranial or caudal cruciate ligament. Only two dogs underwent surgical repair of the caudal cruciate ligament. Anatomical reduction and rigid internal fixation of the distal femoral fractures was performed using a combination of lag screws, Kirschner wires, and bone plates. At the long-term follow-up, all cases had good to excellent return to function, as assessed by force plate analysis and owner assessment of quality of life and satisfaction. Radiographs revealed evidence of complete fracture healing, with moderate to severe osteoarthritis of the stifle.Clinical significance: Bicondylar femoral fractures can be associated with ligament or tendon injuries. Anatomical reduction and internal fixation of bicondylar femoral fractures is recommended and may offer a good to excellent return function, with or without repair of associated caudal cruciate ligament injuries.

Clinical Records

The aim of this paper is to retrospectively assess the long-term clinical and radiological results in a group of patients treated with Brånemark TiUnite implants supporting mostly single-tooth and partial restorations. The clinical records of 90 consecutive patients (mean age 55.9 years; range 21–82 years), treated with 209 Brånemark System MkIII or MkIV TiUnite implants (72 maxillary/137 mandibular; 26 anterior intercanine/183 posterior sites), were analyzed. Indication types were single tooth (n = 21 implants), partial (n = 180) and full arches (n = 8). A delayed loading protocol was applied in 128 implants, while 81 were immediately loaded. Cumulative survival rate and marginal bone remodeling were evaluated. Marginal bone level was evaluated by an independent radiologist from periapical radiographs taken at implant insertion and at long-term follow up. Plaque, probing pocket depth and peri-implant mucosa conditions were also assessed. The results showed the mean follow-up duration was 11.0 years (range 9.6–12.4 years): 181 implants (90.5%) reached at least 10 years follow-up, 100 implants 11 years, and 17 implants 12 years. Overall, 6 implants failed in 4 patients (5 during the first year and 1 after 2 years) resulting in a 97.1% survival rate after 12 years. Mean bone levels at implant insertion and at the last follow up were −0.90 ± 1.16 mm (mean ± SD; n = 169) and −1.49 ± 0.95 mm (n = 195), respectively. Mean marginal bone remodeling from implant insertion to the last follow-up was −0.60 ± 1.17 mm (n = 168). At the last available follow-up, mean pocket depth was 1.65 ± 0.84 mm. Peri-implant mucosa was normal for the majority (97%) of implants. In conclusion, this retrospective long-term study showed excellent survival rate of TiUnite implants as well as favorable marginal bone response and soft tissue conditions.

Background Fractures of the distal end radius are a common upper extremity fracture. Intra-articular distal end radius fractures are recognized as very complex injuries with a variable prognosis. The aim of the study was to assess the long-term functional outcome of patients treated with Joshi's external stabilizing system (JESS) for displaced intra-articular distal end radius fractures. Materials and Methods A total of 170 patients with intra-articular distal end radius fracture were treated with JESS from 2014 to 2017. The patients were followed up at 2, 6 weeks, 6 months, 1, and 2 years (final) after the surgery. The assessment of pain, range of motion, grip strength, and satisfaction were assessed at 6 months, 1, and 2 years (final) follow-up and scored according to modified Mayo wrist scoring system. Results The good and/or excellent results were found in 82.2% of cases. We observed that patients with age less than 50 years had greater prognosis as compared with patients with more than 50 years of age. Final outcome was also found better in males as compared with females at 6 months, 1, and 2 years postoperatively. Conclusion JESS is an effective treatment technique for intra-articular distal end radius fractures in our community. On long-term follow-up of the patients treated with JESS for intra-articular distal end radius fractures, the functional and radiological outcomes were good with low complication rate.

Dynamic Cardiomyoplasty

Objective: Chronically depressed right ventricular (RV) function presents an unresolved therapeutic challenge. Despite recent advances in medical and surgical therapies, prognosis remains poor and patient’s quality of life and mortality are frequently unacceptable. The aim of this work is to present the surgical technique and long-term results of RV dynamic cardiomyoplasty applied in patients with RV failure due to isolated RV cardiomyopathies. Methods: Twelve consecutive patients (8 males, 4 females), mean age 37±9 years, were enrolled. All pts had predominant RV dysfunction, associated with tricuspid regurgitation in 11 cases. Etiology of RV failure was arrhythmogenic cardiomyopathy (8 cases), Uhl’s disease (2 cases) and ischemic (2 cases). Patients were in preoperative NYHA FC III. Mean pre-operative EF measured by isotopic technique, was 20 ± 4.2 % for the RV and 37 ± 8 % for the LV. Right ventricular dynamic cardiomyoplasty consists in wrapping the RV free wall with the left Latissimus Dorsi Muscle (LDM) flap. The distal part of the LDM is fixed to the diaphragm and then electrostimulated in synchrony with cardiac function. Eleven patients required associated tricuspid valve surgery (10 annuloplasty rings and 1 valve replacement). In 6 pts an ICD was implanted prior to surgery. Results: Nine patients are alive (mean follow-up: 10 ± 3.5 years), seven in NYHA functional class I and two in class II. Three deaths occurred: one patient died postoperatively due to infection, one patient died at day 45 due to gastroenteric complication and one patient died at year 7 due to stroke, while in functional class II. At long term follow-up, mean RVEF is 32 ± 6 % and LVEF is 51 ± 9 %. Conclusions: The results of this long-term study demonstrate hemodynamic and functional improvements following RV cardiomyoplasty with no long-term malignant arrhythmias and RV dysfunction related deaths. The effects of RV cardiomyoplasty can be related to chronic systolic compression and diastolic dilatation restriction (positive remodeling), which may reduce tension and excitability of myocardial fibers. This study suggests that cardiomyoplasty is a safe alternative or long-term bridge to heart transplantation in these patients with relatively preserved LV function.

Category: Ankle Arthritis, Hindfoot Introduction/Purpose: Triple arthrodesis is a commonly performed surgical treatment for hindfoot arthritis and deformity. No study has clearly delineated correlates of both clinical and radiographic outcomes in a sample size this large. The purpose of this study is to explore predictive and demographic outcome measures with long-term followup after triple arthrodesis. Methods: With IRB approval, an institutional radiology database was queried for patients undergoing triple arthrodesis between 2004 and 2016, by a single surgeon at a single institution. A total of 465 cases were identified. Pre- and post-operative clinical and radiographic data was collected retrospectively. Demographic and predictive data included: age, Body Mass Index (BMI), American Society of Anesthesiologists Score (ASA), Charleston Comorbidity Index (CCI), diabetic status, osteoporosis, hypothyroidism, and neuromuscular disease status. Clinical outcomes including infection rate, reoperation rate and clinical nonunion were recorded. Unintended return to the operating room defined clinical failure. Radiographic data including non-union rate, pre- and post- operative ankle degenerative joint disease was also recorded. Statistical analysis was then performed to evaluate the relationship between predictive measures and various outcomes including reoperation, infection, and non-union rates. 23 cases were lost to follow-up. Results: A total of 442 feet (397 patients) were analyzed. The average age was 54 years (14 to 85) with the majority of cases being female (60%). Average follow up was 593 days (40 to 4079). Overall failure rate was 13.7% with clinical nonunion rate of 4.5%. Infection rate was 5.9%. Mortality rate was 0% at 2 years post-operatively. Predictors of failure included: increased BMI, elevated ASA, history of diabetes, underlying neuromuscular disorder (Figure 1). We found no significant difference between pre and post-operative degenerative joint disease rates in the midfoot (9.4%, 12.5%) and ankle (11.7%,13.7%), respectively. Conclusion: Triple arthrodesis is a highly effective procedure for treating hindfoot arthritis. Certain predictive measures including BMI, ASA score, diabetic status and underlying neuromuscular disorders significantly correlate with radiographic union. Additionally, diabetic status significantly correlates with infection status postoperatively. An understanding of these predictive measures may help surgeons in their preoperative planning to improve their clinical and radiographic success rates.
