Aims. In approximately 20% of patients with ankle fractures, there is an concomitant injury to the syndesmosis which requires stabilisation, usually with one or more syndesmotic screws. The aim of this review is to evaluate whether removal of the syndesmotic screw is required in order for the patient to obtain optimal functional recovery. Materials and Methods. A literature search was conducted in Medline, Embase and the Cochrane Library for articles in which the syndesmotic screw was retained. Articles describing both removal and retaining of syndesmotic screws were included. Excluded were biomechanical studies, studies not providing patient related outcome measures, case reports, studies on skeletally immature patients and reviews. No restrictions regarding year of publication and language were applied. Results. A total of 329 studies were identified, of which nine were of interest, and another two articles were added after screening the references. In all, two randomised controlled trials (RCT) and nine case-control series were found. The two RCTs found no difference in functional outcome between routine removal and retaining the syndesmotic screw. All but one of the case-control series found equal or better outcomes when the syndesmotic screw was retained. However, all included studies had substantial methodological flaws. Conclusions. The currently available literature does not support routine elective removal of syndesmotic screws. However, the literature is of insufficient quality to be able to draw definitive conclusions. Secondary procedures incur a provider and institutional cost and expose the patient to the risk of complications. Therefore, in the absence of high quality evidence there appears to be little justification for routine removal of syndesmotic screws. Cite this article: Bone Joint J 2016;98-B:1497–1504

Aims. The aim of this study was to investigate whether on-demand removal (ODR) is noninferior to routine removal (RR) of syndesmotic screws regarding functional outcome. Methods. Adult patients (aged above 17 years) with traumatic syndesmotic injury, surgically treated within 14 days of trauma using one or two syndesmotic screws, were eligible (n = 490) for inclusion in this randomized controlled noninferiority trial. A total of 197 patients were randomized for either ODR (retaining the syndesmotic screw unless there were complaints warranting removal) or RR (screw removed at eight to 12 weeks after syndesmotic fixation), of whom 152 completed the study. The primary outcome was functional outcome at 12 months after screw placement, measured by the Olerud-Molander Ankle Score (OMAS). Results. There were 152 patients included in final analysis (RR = 73; ODR = 79). Of these, 59.2% were male (n = 90), and the mean age was 46.9 years (SD 14.6). Median OMAS at 12 months after syndesmotic fixation was 85 (interquartile range (IQR) 60 to 95) for RR and 80 (IQR 65 to 100) for ODR. The noninferiority test indicated that the observed effect size was significantly within the equivalent bounds of -10 and 10 scale points (p < 0.001) for both the intention-to-treat and per-protocol, meaning that ODR was not inferior to RR. There were significantly more complications in the RR group (12/73) than in the ODR group (1/79) (p = 0.007). Conclusion. ODR of the syndesmotic screw is not inferior to routine removal when it comes to functional outcome. Combined with the high complication rate of screw removal, this offers a strong argument to adopt on demand removal as standard practice of care after syndesmotic screw fixation.

Aims. The primary aim of this study was to present the mid-term follow-up of a multicentre randomized controlled trial (RCT) which compared the functional outcome following routine removal (RR) to the outcome following on-demand removal (ODR) of the syndesmotic screw (SS). Methods. All patients included in the ‘ROutine vs on DEmand removal Of the syndesmotic screw’ (RODEO) trial received the Olerud-Molander Ankle Score (OMAS), American Orthopaedic Foot and Ankle Hindfoot Score (AOFAS), Foot and Ankle Outcome Score (FAOS), and EuroQol five-dimension questionnaire (EQ-5D). Out of the 152 patients, 109 (71.7%) completed the mid-term follow-up questionnaire and were included in this study (53 treated with RR and 56 with ODR). Median follow-up was 50 months (interquartile range 43.0 to 56.0) since the initial surgical treatment of the acute syndesmotic injury. The primary outcome of this study consisted of the OMAS scores of the two groups. Results. The median OMAS score was 85.0 for patients treated with RR, and 90.0 for patients treated with ODR (p = 0.384), indicating no significant difference between ODR and RR. The secondary outcome measures included the AOFAS (88.0 in the RR group and 90.0 for ODR; p = 0.722), FAOS (87.5 in the RR group and 92.9 for ODR; p = 0.399), and EQ-5D (0.87 in the RR group and 0.96 for ODR; p = 0.092). Conclusion. This study demonstrated no functional difference comparing ODR to RR in syndesmotic injuries at a four year follow-up period, which supports the results of the primary RODEO trial. ODR should be the standard practice after syndesmotic screw fixation. Cite this article: Bone Jt Open 2023;4(12):957–963

Background. Anatomical reduction of unstable Lisfranc injuries is crucial. Evidence as to the best methods of surgical stabilization remains sparse, with small patient numbers a particular issue. Dorsal bridge plating offers rigid stability and joint preservation. The primary aim of this study was to assess the medium-term functional outcomes for patients treated with this technique at our centre. Additionally, we review for risk factors that influence outcomes. Methods. 85 patients who underwent open reduction and dorsal bridge plate fixation of unstable Lisfranc injuries between January 2014 and January 2019 were identified. Metalwork was not routinely removed. A retrospective review of case notes was conducted. The Manchester-Oxford Foot Questionnaire summary index (MOXFQ-Index) was the primary outcome measure, collected at final follow-up, with a minimum follow-up of 24 months. The American Orthopedic Foot and Ankle Society (AOFAS) midfoot scale, complications, and all-cause re-operation rates were secondary outcome measures. Univariate and multivariate analyses were used to identify risk factors associated with poorer outcomes. Results. Mean follow-up 40.8 months (24–72). Mean MOXFQ-Index 27.0 (SD 7.1). Mean AOFAS score 72.6 (SD 11.6). 48/85 patients had injury patterns that included an intra-articular fracture and this was associated with poorer outcomes, with worse MOXFQ and AOFAS scores (both p < 0.001). 18 patients (21%) required the removal of metalwork for either prominence or stiffness. Female patients were more likely to require metalwork removal (OR 3.89, 95% CI 1.27 to 12.0, p = 0.02). Eight patients (9%) required secondary arthrodesis. Conclusions. This is the largest series of Lisfranc injuries treated with dorsal bridge plate fixation reported to date and the only to routinely retain metalwork. The technique is safe and effective. The presence of an intraarticular fracture is a poor prognostic indicator. Metalwork removal is more likely to be needed in female patients but routine removal may not be essential

Introduction. Retention and removal of children's orthopaedic metalwork is a contentious issue that has implications for current resource allocation, health economics, complication risks and can impact on future treatments. Understanding how to guide families make informed choices requires an overview of all the relevant evidence to date, and knowledge of where the evidence is lacking. Our aim was to systematically review the literature and provide a meta-analysis where possible, recommending either retention or removal. Materials and Methods. A search of the literature yielded 2420 articles, of which 22 papers were selected for the study analysis. Inclusion criteria: Any paper (evidence level I-IV) assessing the risks or benefits of retaining or removing orthopaedic metalwork in children. Exclusion criteria: Spinal implants; implant number < 40; < 75% recorded follow up; papers including implants in their analysis that always require removal; patients aged >18 years. Results. In total, 4988 patients (6412 implants) were included across all 22 studies. There was a significant amount of heterogenicity between studies. Overall the short term risks of metalwork retention and removal are low, with a few exceptions. In forearm plating re-fracture rates following removal were lower than those seen in studies looking at retained metalwork, provided removal occurred later than 12 months from the initial operation. Forearm re-fracture rates after removal of flexible nails significantly increased if removal was performed before 6 months. Major complications following routine metalwork removal from the proximal femur are relatively rare, with re-fracture rates of 1–5%. The majority of these re-fractures are seen in neuromuscular patients or in patients where removal occurs earlier than 6 months. Routine metalwork removal following SUFE had a complication rate of 30–60%. Conclusions. We found that there are certain subgroups of children that benefit from retention of metalwork and some that benefit from removal. There are several subgroups that we have identified which do not yet have sufficient long term evidence to make a balanced recommendation. We advise that families are made aware of what is known and what is unknown in order to allow for shared decision making

We have reviewed the complication rate over a ten year period for removal of screws placed for slipped capital femoral epiphysis (SCFE) and have surveyed the views of orthopaedic surgeons with an adult hip practice in Scotland on leaving the metalwork in situ. Whilst screw removal is favoured by many orthopaedic surgeons, a recent review of the literature reported that the complication rate for removal of implants placed for SCFE was 34%. Between 1998 and 2007 84 patients had insertion of screws for SCFE. Of these 54 patients had screws removed, 51 of these records were available. The median duration between insertion and removal of screws was 2 yrs 7 months. Of the 51 children, overall five (9.8%) had complications - three (5.9%) major and two (3.9%) minor. Two screws could not be removed; one patient sustained a fracture after screw removal and two developed an infection. We assessed the attitudes of adult hip surgeons on this topic using an electronic questionnaire which was completed by 29 out of 40 recipients. 78.6% of respondents support routine removal and 21.4% favour leaving the screw permanently in place. 82.2% had needed to remove metalwork from a hip requiring arthroplasty in a patient whose metalwork was inserted during childhood; and described their experience of this including the complications encountered. We have identified a lower complication rate following screw removal inserted for SCFE than in published series. Most adult hip surgeons support routine removal once the physis is closed but studies regarding the long-term outcome of retained orthopaedic implants are needed since even with this lower complication rate the question of routine removal remains unclear

Aim. Treatment algorithms for fracture-related nonunion depend on the presence or absence of bacterial infection. However, the manifestation of septic nonunion varies. Low-grade infections, unlike manifest infections, lack clinical signs of infection and present similarly to aseptic nonunion. The clinical importance of low-grade infection in nonunion is not entirely clear. Therefore, the aim of this study was to evaluate the clinical relevance of low-grade infection in the development and management of femoral or tibial nonunion. Method. A prospective, multicenter clinical study enrolled patients with nonunion and regular healed fractures. Preoperatively, complete blood count without differential, C-reactive protein (CRP), and procalcitonin were obtained, clinical signs of infection were recorded, and a suspected septic or aseptic diagnosis was made based on history and clinical examination. During surgical nonunion revision or routine implant removal, tissue samples were collected for microbiology and histopathology, and osteosynthesis material for sonication. Nonunion patients were followed for 12 months. Definitive diagnosis of “septic” or “aseptic” nonunion was made according to diagnostic criteria for fracture-related infection, considering the results of any further revision surgery during follow-up. Results. 34 patients with regular healed fractures were included. 62 nonunion patients were diagnosed as aseptic, 22 with manifest, and 23 with low-grade infection. The positive predictive value was 88% and the negative predictive value 72% for the suspected diagnosis. The nonunion groups had significantly higher CRP levels than the regular healer group. Differentiation between septic and aseptic nonunion based on blood values was not possible. Low-grade infection demonstrated less frequently histopathologic signs of infection than manifest infection (22% vs. 50%, p=0.048), with 15% of regular healers having histopathologic signs of infection. Cutibacterium acnes was less present in manifest compared to low-grade infection (p=0.042). Healing rates for septic nonunion involving C. acnes were significantly lower for manifest infection (20%) than for low-grade infection (100%, p=0.002). Patients with low-grade infection were treated with systemic antibiotics less frequently than patients with manifest infection (p=0.026), with no significant difference in healing rate (83% vs. 64%), which was slightly lower for low-grade infection than for aseptic nonunion (90%). Conclusions. Low-grade infections play a significant role in nonunion development and are difficult to diagnose preoperatively due to the lack of clinical signs of infection and unremarkable blood counts. However, our results imply that for low-grade infections, antibiotic therapy may not always be mandatory to heal the nonunion.

Introduction. Angular deformities of the distal femur can be corrected by opening, closing and neutral wedge techniques. Opening wedge (OW) and closing wedge (CW) are popular and well described in the literature. CW and OW techniques lead to leg length difference whereas the advantage of neutral wedge (NW) technique has several unique advantages. NW technique maintains limb length, wedge taken from the closing side is utilised on the opening side and since the angular correction is only half of the measured wedge on either side, translation of distal fragment is minimum. Leg lengths are not altered with this technique hence a useful technique in large deformities. We found no reports of clinical outcomes using NW technique. We present a technique of performing external fixator assisted NW correction of large valgus and varus deformities of distal femur and dual plating and discuss the results. Materials & Methods. We have treated 20 (22 limbs – 2 patients requiring staged bilateral corrections) patients for distal femoral varus and valgus deformities with CWDFO between 2019 and 2022. Out of these 4 patients (5 limbs) requiring large corrections of distal femoral angular deformities were treated with Neutral Wedge (NW) technique. 3 patients (four limbs) had distal femoral valgus deformity and one distal femoral varus deformity. Indication for NW technique is an angular deformity (varus or valgus of distal femur) requiring > 12 mm opening/closing wedge correction. We approached the closing side first and marked out the half of the calculated wedge with K – wires in a uniplanar fashion. Then an external fixator with two Schanz screws is applied on the opposite side, inserting the distal screw parallel to the articular surface and the proximal screw 6–7 cm proximal to the first pin and at right angles to the femoral shaft mechanical axis. Then the measured wedge is removed and carefully saved. External fixator is now used to close the wedge and over correct, creating an appropriate opening wedge on the opposite side. A Tomofix (Depuoy Synthes) plate is applied on the closing side with two screws proximal to osteotomy and two distally (to be completed later). Next the osteotomy on the opposite side is exposed, the graft is inserted. mLDFA is measured under image intensifier to confirm satisfactory correction. Closing wedge side fixation is then completed followed by fixation of opposite side with a Tomofix or a locking plate. Results. 3 patients (4 limbs) had genu valgum due to constitutional causes and one was a case of distal femoral varus from a fracture. Preoperative mLDFA ranged from 70–75° and in one case of varus deformity it was 103°. We achieved satisfactory correction of mLDFA in (85–90°) in 4 limbs and one measured 91°. Femoral length was not altered. JLCA was not affected post correction. Patients were allowed to weight bear for transfers for the first six weeks and full weight bearing was allowed at six weeks with crutches until healing of osteotomy. All osteotomies healed at 16–18 weeks (average 16.8 weeks). Patients regained full range of movement. We routinely recommend removal of metal work to facilitate future knee replacement if one is needed. Follow up ranged from 4 months to 2 yrs. Irritation from metal work was noted in 2 patients and resolved after removing the plates at 9 months post-surgery. Conclusions. NWDFO is a good option for large corrections. We describe a technique that facilitates accurate correction of deformity in these complex cases. Osteotomy heals predictably with uniplanar osteotomy and dual plate fixation. Metal work might cause irritation like other osteotomy and plating techniques in this location

Fractures of the lateral clavicle with complete displacement have a high non-union rate and are associated with poor functional outcomes following non-operative treatment. Various operative techniques are available but preliminary studies of open reduction and tunnelled suspensory device (ORTSD) fixation report good early functional outcomes with a low rate of complications. This study assesses the functional outcomes in a large series of patients treated using ORTSD. After surgical reconstruction in 67 patients, outcomes were assessed using the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire and Oxford score at six weeks, and three, six and twelve months post-operatively. 55 of 64 surviving patients were contacted at a mean of 69 (27–120) months to complete DASH and Oxford scores, evaluate overall satisfaction, and document any complications. At one year post-operatively, the mean Oxford score was 46.4 and mean DASH score was 2.4 points (59/67 patients assessed). At a mean of 69 months after surgery, the mean Oxford score was 46.5 and mean DASH score was 2.2 (55 surviving and contactable patients). There were no significant differences between the one-year functional scores and those at the latest follow-up. Two patients developed symptomatic non-union requiring re-operation, and two developed an asymptomatic fibrous union not requiring surgery. The five-year survival when considering only obligate revision for implant-related complications was 97.0%. ORTSD fixation for isolated displaced lateral-end clavicle fractures in medically-fit patients is associated with good functional outcomes, and a low rate of medium-term complications. Routine removal of the implant was not necessary

A new apparatus and technique of syndesmosis fixation is tested in a prospective clinical study. Buttons on both sides of the ankle anchor a strong suture under tension following syndesmosis reduction. This syndesmosis suture acts like a tightrope when under tension. Implantation is simple with a minimally invasive technique, as the medial side is not opened. It allows physiological micromotion whilst resisting diastasis, does not require routine removal, and allows patients to weight-bear earlier. Sixteen patients with Weber C ankle fractures with a syndesmosis diastasis underwent suture-button fixation and the results compared to 16 consecutive patients with syndesmosis screw fixation. Patients were, in effect, quasi-randomised according to surgeon preference. Mean A,O,F,A,S, ankle scores were significantly better in the suture-button group at three months post-op (91 vs 80, p=0.01, unpaired t-test) and at twelve months (93 vs 83, p=0.04, unpaired t-test). Return to work was also significantly faster (2.6 months vs 4.6 months, p=0.02, unpaired t-test). No suture-buttons required implant removal. Axial CT scanning at three months showed implants to be intact with maintenance of reduction, as compared to the uninjured contralateral side. Suture-button syndesmosis fixation is simple, safe and effective. It has shown improved outcomes and faster rehabilitation, without needing routine removal. Although the apparatus design may undergo further refinement, we believe this technique will become the treatment of choice in Weber C ankle fractures with a syndesmosis injury

Introduction A new technique of ankle syndesmosis fixation is proposed. Buttons are placed on both sides of the ankle, connected by a strong non-absorbable suture. The technique is simple and minimally invasive: a medial incision is not required. It resists diastasis whilst allowing physiological micromotion and does not require routine removal. Methods The technique was tested on a cadaver model of a Maisonneuve injury under increasing torque loads. Sixteen embalmed cadaver legs were randomised to receive suture-button fixation or four-cortical 4.5 mm syndesmosis screw fixation. A prospective clinical study involving 16 patients with Weber C fractures and syndesmosis diastasis is presented. They underwent suture-button fixation and the results were compared to 16 consecutive patients with syndesmosis screw fixation. Results In the cadaver study, both groups had similar rates of diastasis following torque loading. However, the suture-button did give a more consistent performance: standard deviations were significantly lower (p=0.001) than the screw group. In the clinical study, both groups were evenly matched as regards patient age, male: female ratio, and fracture patterns. Mean AOFAS ankle outcome scores at three months were significantly better in the suture-button group (91 versus 82, p=0.01). No suture-button patients required implant removal. They had a faster return to work compared to the screw group (three months versus five months). Axial CT scanning performed at three months post-op showed all implants to be intact with no loss of reduction. Conclusions Suture-button syndesmosis fixation is simple, safe, effective and physiological. It has shown improved outcomes and faster rehabilitation, without needing routine removal. It may become the treatment of choice in Weber C ankle fractures with a syndesmosis diastasis. In relation to the conduct of this study, one or more the authors have received, or are likely to receive direct material benefits

During the period of January 1999 and August 2004 there was a policy in our institution of removal for metalwork from patients who underwent open reduction and internal fixation of an ankle fracture. We were not able to find any evidence in the literature as to whether implant removal confers long-term benefit or disability in these patients. Between January 1999 to August 2003, all patients who underwent ankle metalwork removal were reviewed. Most patients with mechanical symptoms were improved by implant removal. The two infections resolved. In those patients with pain, about two thirds found were improved. Following this study the practice in our institution has changed. We do not feel routine removal of metalwork is warranted unless there are specific indications; mainly mechanical symptoms, infection and pain. We are particularly keen to counsel patients from the latter category, that surgery may not resolve their symptoms

Aims: A new technique of syndesmosis fixation is proposed; placing buttons on both sides of the ankle, without opening the medial side, connected by a strong non-absorbable suture. We tested this against syndesmosis screw fixation in a cadaver model of a Maisonneuve injury and subsequently in a prospective clinical study. Methods: 16 cadaver legs were randomised to have suture-button or syndesmosis screw fixation and tested under torque loading. In the clinical study, 16 patients with a syndesmosis diastasis underwent suturebutton fixation and the results compared to 16 patients with syndesmosis screw fixation. Results: In the cadaver study, both groups had similar rates of diastasis, although the suture-button did give a more consistent performance: standard deviations were significantly lower (p=0.001). In the clinical study, mean A.O.F.A.S. scores at 3 months were significantly better in the suturebutton group (91 vs 82, p=0.01). No suture-button implants required removal, compared to 13/16 of the screw group (p=0.001). Conclusions: Suture-button syndesmosis fixation is simple, safe and physiological. Biomechanically it performs at least as well as screw fixation. Clinically it has shown improved outcomes, without needing routine removal. It may become the treatment of choice in syndesmosis injuries

Aim: Controversy remains regarding the complications/necessity for removal of metalwork used in the fixation of paediatric orthopaedic surgery owing to potential complications of removal. It was the aim of this study to review all cases of metalwork removal performed in a prescribed year in order to ascertain the reasons for removal and complications of these surgeries. Methods: All cases of metalwork removal performed under GA, from 1st January 2006 until 31st December 2006 in a regional paediatric orthopaedic unit, were reviewed. Data were obtained from case notes, computer and theatre records and radiographs. Details were obtained regarding demographic details, anatomic site, implant used, reasons for removal, problems of initial fixation and complications after removal. Results: 34 buried kirschner wires were removed under general anaesthetic. Of other metal work, 38 implants were removed; 22 in males and 16 in females. The commonest age distribution was the 11–15 age groups. The most common anatomic site for removal was the forearm (42%) followed by the femur (18%) and ankle (18%). The most common implant removed was plate (53%), followed by Nancy nails (18%). Problems following initial insertion were found in 4 patients (10.5%) including re-fracture distal to forearm plates (both in patients with co-existing osteopaenia), bowing of forearm and decreased sensation over the thumb. Metal work was removed for symptoms in 13 cases (34%) and the rest for patient request or clinical indications. Complications after metalwork removal occurred in 8 (21%) patients and included re-fracture of forearm (2), hypertrophic scar, abscess, skin reaction, wound breakdown, excessive bruising and discomfort. Conclusion: As routine removal of metalwork is generally considered not necessary, metalwork removal is often carried out for symptoms, at patient request as well as in patients with osteopaenia who have risk of fracture at the ends of metalwork. Parents need to be made aware of possible complications shown in the study, in order to give informed consent
