Abstract
BACKGROUND Supramalleolar osteotomy (SMOT) has emerged as a valuable treatment for ankle varus deformity; however, there are fewer reports of treatment outcomes in adolescents. The purpose of this study was to investigate the radiologic and clinical outcomes of SMOT for the treatment of traumatic ankle joint varus deformity (TAVD) in adolescents. METHODS We reviewed 32 adolescent cases who underwent SMOT between February 2017 and February 2022 for TAVD. Radiologic assessment included tibial anterior surface angle (TAS), talar tilt angle (TT), and tibial lateral surface angle (TLS) preoperatively and at 3 months and 12 months postoperatively, and clinical assessment was performed using American Orthopaedic Foot and Ankle Society (AOFAS) scores, Visual Analogue Scale (VAS) scores, and ankle dorsiflexion-plantarflexion ROM including preoperative and 6 months postoperative and 12 months postoperative. RESULTS All 32 patients were followed up completely with a mean follow-up of (20.3 ± 3.2) months. From the radiologic outcomes, the mean preoperative TAS improved from 61.53 ± 3.74 to 88 ± 1.72 at 12 months postoperatively, the mean preoperative TT decreased from 2.25 ± 1.32 to 0.5 ± 0.57 at 12 months postoperatively, the mean preoperative TLS improved from 76.72 ± 0.21 to 79.34 ± 1.52 at 12 months postoperatively, the differences between the above preoperative and 12 months postoperative radiologic outcomes were statistically significant (p < 0.05), the mean preoperative AOFAS score improved from 65.5 ± 9.40 to 92.34 ± 4.00 at 12 months postoperatively, the mean preoperative VAS score decreased from 2.44 ± 1.24 to 0.78 ± 0.75 at 12 months postoperatively, and the mean preoperative range of motion (ROM) of ankle improved from 50.16 ± 7.46 to 55.78 ± 4.77 at 12 months postoperatively. The differences between the above preoperative and 12 months postoperative clinical results were statistically significant (p < 0.05). CONCLUSION Our study demonstrated that SMOT was effective in correcting TAVD and significantly improving ankle function in adolescents, and that it is an efficient and successful method for restoring ankle joint congruence and normal hindfoot alignment.

[PMID: 37010603 DOI: 10.1007/s00402-023-04867-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/07/2022] [Accepted: 03/27/2023] [Indexed: 04/04/2023]
Abstract
INTRODUCTION We investigated the mid-term outcomes of supramalleolar osteotomies regarding "survivorship" [before ankle arthrodesis (AA) or total ankle replacement (TAR)], complication rate and adjuvant procedures required. MATERIAL AND METHODS PubMed, Cochrane and Trip Medical Database were searched from January 01, 2000. Studies reporting on SMOs for ankle arthritis, in minimum of 20 patients aged 17 or older, followed for a minimum of two years, were included. Quality assessment was performed with the Modified Coleman Methodology Score (MCMS). A subgroup analysis of varus/valgus ankles was performed. RESULTS Sixteen studies met the inclusion criteria, with 866 SMOs in 851 patients. Mean age of patients was 53.6 (range 17-79) years, and mean follow-up was 49.1 (range 8-168) months. Of the arthritic ankles (646 ankles), 11.1% were classified as Takakura stage I, 24.0% as stage II, 59.9% as stage III and 5.0% as stage IV. The overall MCMS was 55.2 ± 9.6 (fair). Eleven studies (657 SMOs) reported on "survivorship" of SMO, before arthrodesis (2.7%), or total ankle replacement (TAR) (5.8%) was required. Patients required AA after an average of 44.6 (range 7-156) months, and TAR after 36.71 (range 7-152) months. Hardware removal was required in 1.9% and revision in 4.4% of 777 SMOs. Mean AOFAS score was 51.8 preoperatively, improving to 79.1 postoperatively. Mean VAS was 6.5 preoperatively and improved to 2.1 postoperatively. Complications were reported in 5.7% (44 out of 777 SMOs). Soft tissue procedures were performed in 41.0% (310 out of 756 SMOs), whereas concomitant osseous procedures were performed in 59.0% (446 out of 756 SMOs). SMOs performed for valgus ankles failed in 11.1% of patients, vs 5.6% in varus ankles (p < 0.05), with disparity between the different studies. CONCLUSIONS SMOs combined with adjuvant, osseous and soft tissue, procedures, were performed mostly for arthritic ankles of stage II and III, according to the Takakura classification and offered functional improvement with low complication rate. Approximately, 10% of SMOs failed and patients required AA or TAR, after an average of just over 4 years (50.5 months) after the index surgery. It is debatable whether varus and valgus ankles treated with SMO reveal different success rates.

Park YH, Lee HJ, Choi JW, Kim HJ. Value of postoperative computed tomography for the diagnosis of lateral hinge fracture in medial opening-wedge supramalleolar osteotomy. Arch Orthop Trauma Surg 2023; 143:1379-1385. [PMID: 35039915 DOI: 10.1007/s00402-021-04301-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/15/2021] [Accepted: 12/02/2021] [Indexed: 11/02/2022]
Abstract
INTRODUCTION It remains unclear whether computed tomography (CT) is superior to plain radiography in detecting lateral hinge fractures after medial opening-wedge supramalleolar osteotomy (SMO) of the ankle joint. This study aimed to evaluate the disparity between postoperative plain radiography and CT in detecting lateral hinge fractures after medial opening-wedge SMO and to identify the predictive factors of lateral hinge fractures. MATERIALS AND METHODS This retrospective study included 39 patients who underwent medial opening-wedge SMO. The immediate postoperative plain radiography and CT scan images were retrieved, and the presence of lateral hinge fractures was independently determined. Depending on the fracture gap, the lateral hinge fractures were subclassified as stable (gap < 2 mm) or unstable (gap ≥ 2 mm) fractures. To investigate the predictive factors, the cases were divided based on diagnostic tools such as plain radiography and CT. RESULTS The incidence of lateral hinge fractures was 48.7% (19/39) on plain radiographs and 61.5% (24/39) on CT scans. Five cases of lateral hinge fractures additionally detected on CT scans were stable fractures, and all had been classified as no fracture on plain radiographs. The unstable fractures that had been subclassified based on plain radiographs did not change on CT scans. None of the variables were associated with the presence of lateral hinge fractures on plain radiographs and CT scans. CONCLUSIONS Postoperative CT after medial opening-wedge SMO has no additional diagnostic value if the lateral hinge fracture has already been diagnosed on plain radiography. Therefore, postoperative CT is only recommended when lateral hinge fractures are not visible on plain radiographs.

Supramalleolar osteotomy for the treatment of ankle osteoarthritis leads to favourable outcomes and low complication rates at mid-term follow-up: a systematic review. Knee Surg Sports Traumatol Arthrosc 2023; 31:701-715. [PMID: 36151410 DOI: 10.1007/s00167-022-07144-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/18/2022] [Accepted: 08/26/2022] [Indexed: 02/07/2023]
Abstract
PURPOSE The purpose of this systematic review was to evaluate both the clinical and radiographic outcomes following supramalleolar osteotomy (SMO) in patients with ankle osteoarthritis, and to analyse the level of evidence (LOE) and quality of evidence (QOE) of the included studies. METHODS A systematic review of the MEDLINE, EMBASE, and Cochrane Library databases was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies reporting clinical data following SMO for the treatment of ankle osteoarthritis were included and assessed. The level and quality of evidence of the included studies were also evaluated. RESULTS Twenty-four studies with 1160 patients (1182 ankles) were included. Overall, 78.8% patients presented with post-traumatic ankle osteoarthritis. The weighted mean AOFAS score improved from 52.6 ± 9.7 (range 33.8-78.4) preoperatively to 78.1 ± 5.7 postoperatively at weighted mean follow-up of 50.4 ± 18.6 months (range 24.5-99.0). The most frequently utilised radiographic parameter was the tibial anterior surface angle, which improved from a preoperative weighted mean of 86.3° ± 5.6° (range 76.0°-102.0°) to a postoperative weighted mean of 89.9° ± 3.7° (range 84.9°-99.6°). The complication rate was 5.1% with non-union as the most commonly reported complication (1.6%). Secondary procedures were carried out in 28.2% of patients, the most common of which was implant and hardware removal (17.6%). The failure rate was 6.8%. Two studies were LOE II, 3 studies were LOE III, and 19 studies were LOE IV. The mean Modified Coleman Methodology Score was 59.3 ± 6.6 and the mean MINORS criteria score of all the included studies was 9.5 ± 3.7. CONCLUSION This systematic review demonstrates good clinical and radiological outcomes, together with a low failure rate at mid-term follow-up following supramalleolar osteotomy in patients with ankle osteoarthritis. However, a moderate reoperation rate (28.2%) was reported. A low failure rate (6.8%) was reported, which must be interpreted in light of the shortcomings of the design of the included studies and a relatively short follow-up period. In addition, there is a low level and quality of evidence in the current literature with inconsistent reporting of data which underscores the need for further higher quality research to be conducted. Our review highlights that SMO may be an effective and safe procedure in the setting of early-to-intermediate-stage ankle osteoarthritis. LEVEL OF EVIDENCE IV.

Abstract
BACKGROUND There is no consensus on the angle targeted for in varus ankle deformity after supramalleolar osteotomy (SMOT). The aim of this study was to investigate which obtained correction has the best clinical outcome after valgus SMOT. METHODS A systematic review according PRISMA guidelines was conducted with studies being eligible for inclusion when published in English, German or Dutch, patients older than 18 years at study entrance, primary or posttraumatic varus ankle osteoarthritis, using any valgus SMOT technique, describing radiological alignment and clinical outcome at baseline and after at least 12 months follow-up. Risk of bias was assessed using the McMaster University Occupational Therapy Evidence-Based Practice Research Group quality assessment tool. The electronical databases PubMed, EMBASE and Cinahl were used as data sources. Included cohorts were categorized according to the mean obtained medial distal tibia angle (MDTA; ranged between 87° and 100°). A linear mixed effect model was used for individual patient data to assess the association between the MDTA and the (difference in) clinical outcome. RESULTS Thirty studies including 33 patient cohorts with 922 ankles were identified. At a mean follow-up of 4 years no differences in clinical outcome between correction categories were found. Individual data of 34 ankles showed no relationship between obtained MDTA and clinical outcome either. CONCLUSION This review could not demonstrate an optimal degree of correction after valgus SMOT. Results were hampered by biased low quality studies and the widespread use of unreliable 2D alignment measures such as the MDTA.

Abstract
Supramalleolar osteotomy (SMO) is an effective treatment for intermediate-stage varus ankle osteoarthritis (OA). This study aimed to investigate how clinical outcomes were associated with radiological changes and cartilage regeneration shown on arthroscopy before and after SMO in patients with intermediate-stage varus ankle OA. Twenty-six cases with intermediate-stage varus ankle OA underwent SMO with at least 1 year of postoperative follow-up. Clinical assessment was performed preoperatively and postoperatively using the visual analog scale (VAS), American Orthopedic Foot and Ankle Society ankle-hindfoot (AOFAS) scores, and their associations with postoperative changes in tibial ankle surface angle (TAS), talar tilt, tibial lateral surface angle, and heel alignment ratio. The degrees of cartilage regeneration in the tibia plafond and talar dome were observed via second-look arthroscopy. Afterward, their associations with the corresponding clinical outcomes were analyzed. There were significant changes in the TAS, talar tilt, and heel alignment ratio (p < .001, for all). However, there were no significant changes in the tibial lateral surface angle (p = .864) at the final follow-up compared to its preoperative value. Postoperative changes in TAS (p = .013) and the degree of cartilage regeneration (p = .028) in the talar dome significantly influenced the final follow-up AOFAS score. Changes in the TAS angle and the degree of cartilage regeneration after SMO were predictors of clinical outcomes after SMO. In particular, greater changes in the TAS angle corresponded to better clinical outcomes.

Abstract
The aim of supramalleolar conversion osteotomy is to reduce the pain of the patient and stop or at least slow down joint degeneration. The indication for supramalleolar osteotomy is asymmetric osteoarthritis of the ankle joint with varus or valgus deformity. Good clinical results for arthritis can be achieved in the early or middle stages. Besides closing and opening wedge osteotomies dome osteotomy is sometimes indicated, especially for larger deformities. The preoperative preparation of individual patient-specific section blocks facilitates the intraoperative implementation and seems to increase the precision. Further studies are necessary to support this. The indications for additional procedures, such as fibular osteotomy are still being discussed. Inframalleolar osteotomy and soft tissue interventions are frequently necessary for balancing the foot.
