Athanasios Badekas; Dimitrios Georgiannos; Vasilios Lampridis; Ilias Bisbinas

PurposeHallux valgus is a complex deformity of the first metatarsophalangeal joint, with varus angulation of the first metatarsal, valgus deviation of the great toe and lateral displacement of the sesamoids and the extensor tendons. The aim of the surgery is to achieve correction of the varus deviation of the 1st metatarsal which is considered by some as the primary intrinsic predisposing factor to hallux valgus deformity.MethodsWe retrospectively reviewed 85 patients (107 feet) who underwent an opening wedge osteotomy of the 1st metatarsal for correction of moderate to severe hallux valgus and metatarsus primus varus. A medially applied anatomic pre-contoured locking plate was used for fixation of the osteotomy.ResultsThe mean IMA was decreased from 15.8 (range 12–22) degrees to 7.8 (range 0–12) degrees. The mean pre-operative HVA was 39 (range 21–52) degrees and the mean postoperative HVA was 11.8 (6–19) degrees. The pre-operative AOFAS score was 52 (SD 3.1) and the postoperative score was 85 (SD 5.2).ConclusionThe proximal opening wedge metatarsal osteotomy is a safe, effective and reproducible technique for correction of moderate to severe hallux valgus deformity. The use of a locking plate provides enough control at the fragments, enhancing healing of osteotomy and maintenance of the correction even with a violated proximal lateral cortex.

Complications following Treatment of Trochanteric Fractures with the Gamma3 Nail: Is the Latest Version of Gamma Nail Superior to Its Predecessor?

Dimitrios Georgiannos; Vasilios Lampridis; Ilias Bisbinas

Gamma nail is a cephalomedullary implant that was developed for the treatment of pertrochanteric hip fractures and has been successfully used for over 20 years. During this period, modifications of design and instrumentation have occurred to combat the intra- and postoperative complications that were associated with the use of early designs. The purpose of this study was to compare the complications observed with the use of the Gamma3 nail (G3N) with those seen following use of the previous trochanteric gamma nail (TGN). This study prospectively recorded the intra- and postoperative complications of 175 patients treated with the Gamma3 nail and compared them with those of a historical cohort of 192 patients treated with the trochanteric gamma nail. We encountered less intra- and postoperative complications with the use of Gamma3 nail. Femoral fractures and lag screw cutout were significantly lower. The reoperation rate was significantly higher in the TGN group. Gamma3 nail has proved to be a safe and efficient implant for the treatment of pertrochanteric fractures. The improvement of the biomechanical characteristics has led to a significant decrease in complication rates, demonstrating superiority over its predecessor.

Dimitrios Georgiannos; Vasilis Lampridis; Angelos Vasiliadis; Ilias Bisbinas

Background: Insertional Achilles tendinopathy and retrocalcaneal bursitis is difficult to treat, and several operative techniques have been used after failure of conservative management. Dorsal wedge calcaneal osteotomy has been described for the treatment of insertional Achilles pathology. It was hypothesized that dorsal wedge calcaneal osteotomy would be an effective and safe method for the treatment of athletes with insertional Achilles pathology unrelieved by nonoperative measures. Methods: Fifty-two athletes (64 feet) who had painful Achilles tendon syndrome unrelieved by 6 months of nonoperative measures were treated surgically. Dorsally based wedge calcaneal osteotomy was performed through a lateral approach, and 2 staples were used for fixation. Patients were scored pre- and postoperatively with the American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot and Victorian Institute of Sports of Australia-Achilles (VISA-A) scores. Results: At a minimum follow-up of 3 years, the patients’ AOFAS and VISA-A scores improved from 59.5 ± 15.0 and 65.9 ± 11.1 preoperatively to 95.7 ± 6.2 and 90.2 ± 8.4 postoperatively, respectively. Clinical results were considered excellent in 38 patients, good in 12 patients, and fair in 2 patients. Return to previous sports activity time was 21 (SD, 8.0) weeks. One patient necessitated a revision operation. Conclusion: Operative treatment of insertional Achilles pathology in athletes with dorsal closing wedge calcaneal osteotomy was a safe and effective method that allowed for a quicker return to previous level of sports activities compared with other techniques. Level of evidence: Level IV, retrospective case series

Multifocal epithelioid hemangioendothelioma of the foot and ankle: a case report

Ilias Bisbinas; Zacharoula Karabouta; Dimitrios Georgiannos; Vasileios Lampridis; Athanasios Badekas

We report on a 41-year-old man with multiple epithelioid hemangioendothelioma of the left foot and ankle. The patient was treated with curettage and fixation with 2 separate plates, but later developed local infection. Owing to the potential for malignancy, below-knee amputation was suggested, but the patient declined and was treated symptomatically with close monitoring. The patient underwent removal of the plates, excision of the distal fourth of the fibula, intralesional curettage of all lesions, and fusion of the ankle and subtalar joints with a retrograde intramedullary nail. After 5.5 years, the patient had recovered well and had no evidence of malignancy. The tumour was considered definitively benign.

Adhesive Capsulitis of the Shoulder. Is there Consensus Regarding the Treatment? A Comprehensive Review

Dimitrios Georgiannos; George Markopoulos; Eirini Devetzi; Ilias Bisbinas

Background: Adhesive capsulitis of the shoulder (ACS) is a common self-limiting condition characterized by disabling pain and restricted movements. Its pathophysiology is poorly understood, clinically it is characterized by stages of pain and stiffness, and finally often patients never recover fully. However, there is no consensus about available methods of treatment for ACS. The aims of this paper are to discuss and develop issues regarding approaches to management in ACS in the stages of it. Methods: A review of the literature was performed and guidelines for the treatment of that clinical entity for doctors and health care professionals are provided. Results: Anti-inflammatory medications, steroid and/or hyaluronate injections and physiotherapy is the mainstay of conservative management either alone in the first stages or in combination with other treatment modalities in the later stages. Next line of treatment, involving minor to moderate intervention, includes suprascapular nerve block, distension arthrography and manipulation under anaesthesia. In order to avoid complications of “blind intervention”, arthroscopic capsular release is gradually more commonly applied, and in recalcitrant severe cases open release is a useful option. Conclusion: Various modalities of conservative management and gradually more surgical release are applied. However, often clinicians choose on personal experience and training rather than on published evidence.

OBJECTIVES To identify non-surgical treatments which were deemed to be more effective in improving dynamic postural control in patients with chronic ankle instability (CAI). DESIGN Systematic review and random-effects network meta-analysis. METHODS We searched Scopus, CENTRAL, and PubMed until 26 August 2017. We used data from randomized trials comparing the results of different non-surgical interventions for lateral CAI. We assessed dynamic postural control in terms of the star-excursion balance test in the posteromedial direction. We evaluated this outcome at the end of the rehabilitation protocols (i.e., short term) and 6months after treatment (i.e., medium term). We assessed the quality of the included studies with the Cochrane risk of bias tool and evaluated the quality of evidence from the network of interventions using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach. RESULTS Nineteen trials were eligible for inclusion in this systematic review. A 4-6-week supervised balance training program and a 4-6-week strengthening rehabilitation protocol provided significant improvements compared to control (8 studies, standardized mean difference [SMD] was -0.75, 95% CIs [-1.28 to -0.23]); and 2 studies, SMD was -1.2, 95% CIs [-2.36 to -0.08], respectively). A 6-week combined intervention that addressed balance and strength had the highest probability of being among the best treatments. However, the latter rehabilitation intervention was included in only one trial. CONCLUSIONS The network meta-analysis showed that supervised balance training protocols and strengthening programs significantly improved dynamic balance in patients with CAI. A combination of these interventions may further increase the efficacy of non-surgical treatment options for the first-line management of CAI.

Does Multimodal Rehabilitation for Ankle Instability Improve Patients’ Self-assessed Functional Outcomes? A Network Meta-analysis

Konstantinos Tsikopoulos; Dimitris Mavridis; Dimitrios Georgiannos; Haris S. Vasiliadis

Background Although there are many nonsurgical treatment options for the primary management of chronic ankle instability, the most effective nonoperative intervention has not been defined. Questions/purposes The purpose of this study was to perform a network meta-analysis to compare the results of different standalone and/or combined nonsurgical interventions on chronic ankle instability as measured by (1) the Cumberland Ankle Instability Tool (CAIT) at 0 to 6 months after treatment and (2) treatment-related complications. Methods We searched PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), and Scopus in August 2017 for completed studies published between 2005 and 2016. We conducted random-effects pairwise and network meta-analysis considering randomized trials, which compared the effects of various nonoperative therapies for ankle instability. Studies assessing patients with functional ankle instability and/or mechanical ankle instability and/or recurrent ankle sprains were eligible for inclusion. After combining data from self-administered questionnaires, we analyzed patient self-reported outcomes of function at the end of the rehabilitation period and 1 to 6 months after treatment. We thereafter reexpressed standardized mean differences to mean differences with CAIT. For this instrument, scores vary between 0 and 30, and higher scores indicate better ankle stability. We included 21 trials involving 789 chronically unstable ankles. The rehabilitation interventions included, but were not limited to, balance training, strengthening exercises, a combination of the balance and strengthening exercises, manual therapy, and multimodal treatment. The implemented multistation protocols were targeted at four main areas of rehabilitation (ROM, balance, strength, and overall activity). Control was defined as placebo and/or wait and see. Treatment-related complications were defined as any major or minor adverse event observed after rehabilitation as reported by the source studies. Statistically, we did not detect significant inconsistency in the network meta-analysis. We also assessed the quality of the trials using the Cochrane risk of bias tool and judged 12, eight, and one studies to be at a low, unclear, and high risk of bias, respectively. We also considered the quality of evidence to be of moderate strength utilizing the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach. We defined the minimum clinically important difference (MCID) in the CAIT to be 3 points. Results A 4-week supervised rehabilitation program, which included balance training, strengthening, functional tasks, and ROM exercises, was favored over control according to the results of four trials by a clinically important margin (mean difference between multimodal and control groups in the CAIT was -10; 95% confidence interval [CI], -16 to -3; p = 0.001). Among the standalone interventions, only balance training was better than control according to the findings of seven trials (mean difference between balance training and control in the CAIT was -5; 95% CI, -10 to -0.03; p = 0.049); this difference likewise exceeded the MCID and so is believed to be a clinically important difference. Adverse events associated with the enrolled rehabilitation protocols were transient, mild, and uncommon. Conclusions Although a supervised impairment-based program after chronic ankle instability was superior to control, we note that followup in the included trials tended to be short and inconsistent, although the effect size exceeded the MCID and so likely would be identified as clinically important by patients. Future randomized trials should determine whether the short-term benefits of these interventions are sustained over time. Level of Evidence Level I, therapeutic study.

Multifocal Epithelioid Hemangioendothelioma of the Foot and Ankle Developing a Postoperative Infection—Long-term Outcome: A Case Report

Ilias Bisbinas; Zacharoula Karabouta; Vasileios Lampridis; Dimitrios Georgiannos; Athanasios Badekas

A case of rare epithelioid hemangioendothelioma with multiple foot and ankle lytic lesions in a 41-year-old male is reported. The patient presented to our hospital after having received treatment elsewhere and developing a local postoperative infection. After thorough investigations and establishing the diagnosis, we initially treated the local infection and highlighted the potential risk of malignancy. Finally, respecting the patients wishes, he was treated with consideration mostly of the pending foot and ankle fractures rather than the risk of malignancy. At 9.5 years postoperatively, the patient was clinically well and asymptomatic, without clinical, laboratory, or radiologic signs of malignancy, and the previous infection might have even played a remote role in that outcome. A review of the published data regarding the treatment of this unpredictable neoplasm is also presented.

Endoscopic Versus Open Excision of Os Trigonum for the Treatment of Posterior Ankle Impingement Syndrome in an Athletic Population: A Randomized Controlled Study With 5-Year Follow-up:

Dimitrios Georgiannos; Ilias Bisbinas

Background: Open surgical excision of the os trigonum has been the traditional treatment for posterior ankle impingement syndrome (PAIS). However, the endoscopic excision has recently become quite popular. Purpose/Hypothesis: The purpose of our study was to compare the results of endoscopic versus open excision of a symptomatic os trigonum for the treatment of PAIS in an athletic population. It was hypothesized that the endoscopic technique would be superior to the open technique regarding functional outcomes, pain, and time to return to training and the previous sports level. Study Design: Randomized controlled trial; Level of evidence, 2. Methods: From 2008 to 2011, 52 athletes underwent a symptomatic os trigonum excision; 26 athletes had an open procedure (group A) and 26 had an endoscopic procedure (group B). The American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score and the Visual Analog Score–Foot and Ankle (VAS-FA) were obtained, and the time to return to training and to previous sports level was recorded. Results: Patients in group B appeared to have significant improvement of AOFAS hindfoot score compared with those in group A (P < .05), whereas no statistical significance was found for the postoperative VAS-FA scores between the 2 groups. The mean ± SD time to return to training was 9.58 ± 3.98 weeks for group A and 4.58 ± 1.47 weeks for group B (P < .001). The time to return to previous sports level was 11.54 ± 3.89 weeks for group A and 7.12 ± 2.25 weeks for group B (P < .001). The overall complication rate was 23% for group A (6 cases) and 3.8% for group B (1 case). Conclusion: Both the open procedure and the endoscopic approach yielded acceptable outcomes in terms of function and pain. However, complication rates were remarkably lower with endoscopic treatment, and the time to return to full activities was much shorter. Endoscopic excision of the os trigonum is a safe and effective treatment option for athletes who require early return to their previous sports level.

Epithelioid hemangioma of the scapula treated with chemoembolization and microwave ablation: Α case report.

Konstantinos Tsikopoulos; Evangelos Perdikakis; Dimitrios Georgiannos; Ilias Bisbinas

Bone epithelioid hemangiomas are classified within benign vascular tumours but are commonly misdiagnosed as low-grade angiosarcomas or epithelioid hemangioendotheliomas. Current therapeutic interventions include various treatment options but local recurrence or distal lymph node involvement has been reported. We report a rare case of scapular epithelioid hemangioma that was initially treated using a combination of chemoembolization and microwave ablation. This combination has not been previously reported in the literature regarding the management of this tumour. A year after the first course of treatment, the tumour size has been reduced more than 70% and the patient has remarkable clinical improvement. Results reported in this case study demonstrated that combination of chemoembolization and microwave ablation is a feasible, safe and effective technique in the treatment of bone epithelioid hemangiomas. Even if the tumour is still present afterwards, a substantially smaller surgical excision will be needed.
