This prospective randomised trial aimed to assess the superiority of internal fixation of well-reduced medial malleolar fractures (displacement □2mm) compared with non-fixation, following fibular stabilisation in patients undergoing surgical management of a closed unstable ankle fracture. A total of 154 adult patients with a bi- or trimalleolar fracture were recruited from a single centre. Open injuries and vertically unstable medial malleolar fractures were excluded. Following fibular stabilisation, patients were randomised intra-operatively on a 1:1 basis to fixation or non-fixation after satisfactory fluoroscopic fracture reduction was confirmed. The primary outcome was the Olerud Molander Ankle Score (OMAS) at 12 months post-randomisation. Complications were documented over the follow-up period. The baseline group demographics and injury characteristics were comparable. There were 144 patients reviewed at the primary outcome point (94%). The median OMAS was 80 (IQR, 60-90) in the fixation group vs. 72.5 (IQR, 55-90) in the non-fixation group (p=0.165). Complication rates were comparable, although significantly more patients (n=13, 20%) in the non-fixation group developed a radiographic non-union (p<0.001). The majority (n=8/13) were asymptomatic, with one patient requiring surgical reintervention. In the non-fixation group, a superior outcome was associated with an anatomical medial malleolar fracture reduction. Internal fixation is not superior to non-fixation of well-reduced medial malleolar fractures when managing unstable ankle fractures. However, one in five patients following non-fixation developed a radiographic non-union and whilst the re-intervention rate to manage this was low, the longer-term consequences of this are unknown. The results of this trial may support selective non-fixation of anatomically reduced fractures

Aims. Posterior column plating through the single anterior approach reduces the morbidity in acetabular fractures that require stabilization of both the columns. The aim of this study is to assess the effectiveness of posterior column plating through the anterior intrapelvic approach (AIP) in the management of acetabular fractures. Methods. We retrospectively reviewed the data from R G Kar Medical College, Kolkata, India, from June 2018 to April 2023. Overall, there were 34 acetabulum fractures involving both columns managed by medial buttress plating of posterior column. The posterior column of the acetabular fracture was fixed through the AIP approach with buttress plate on medial surface of posterior column. Mean follow-up was 25 months (13 to 58). Accuracy of reduction and effectiveness of this technique were measured by assessing the Merle d’Aubigné score and Matta’s radiological grading at one year and at latest follow-up. Results. Immediate postoperative radiological Matta’s reduction accuracy showed anatomical reduction (0 to 1 mm) in 23 cases (67.6%), satisfactory (2 to 3 mm) in nine (26.4%), and unsatisfactory (> 3 mm) in two (6%). Merle d’Aubigné score at the end of one year was calculated to be excellent in 18 cases (52.9%), good in 11 (32.3%), fair in three (8.8%), and poor in two (5.9%). Matta’s radiological grading at the end of one year was calculated to be excellent in 16 cases (47%), good in nine (26.4%), six in fair (17.6%), and three in poor (8.8%). Merle d’Aubigné score at latest follow-up deteriorated by one point in some cases, but the grading remained the same; Matta’s radiological grading at latest follow-up also remained unchanged. Conclusion. Stabilization of posterior column through AIP by medial surface plate along the sciatic notch gives good stability to posterior column, and at the same time can avoid morbidity of the additional lateral window.

Introduction. Anterior tibial translation (ATT) is assessed in the acutely injured knee to investigate for ligamentous injury and rotational laxity. Specifically, there is a growing recognition of the significance of anterior medial rotary laxity (AMRI) as a crucial element in assessing knee stability. Anterior cruciate ligament (ACL) injuries are often accompanied with medial collateral ligament (MCL) damage. It has been suggested that Deep MCL (dMCL) fibres are a primary restraint in rotational displacement. This research aims to quantify the difference in rotational laxity of patients with ACL and MCL injuries to deem if the Feagin-Thomas test can robustly capture metrics of AMRI. 2. Methods. AMRI was assessed using the Feagin-Thomas test in 7 isolated ACL (iACL) injured participants, 3 combined ACL and superficial fibre MCL (sMCL) injuries, 5 combined ACL and deep fibre MCL injuries, and 21 healthy controls. Displacement values were recorded using an optical motion capture (OMC) system and bespoke processing pipeline which map and model the knee's anterior displacement values relative to the medial compartment. Since absolute values (mm) of rotational laxity vary dependant on the person, values were recorded as a proportion of the rotational laxity obtained from the subject's contralateral leg. Values were compared between each patient group using an ANOVA test and Tukey's honesty significant difference post hoc test. 3. Results. The healthy control group had a median proportion of 0.97 (3SF), whilst the iACL was 1.12 (3SF), a 12% increase in rotational laxity in the injured leg. The sMCL group yielded a result of 1.64 (3SF), a 64% increase in rotational laxity in the injured leg; finally, dMCL resulted in a proportion of rotational laxity of 1.90 (3SF), a 90% increase in rotational laxity [table 1]. Whilst all groups showed differences in the increase of rotational laxity, dMCL was significantly different from the healthy control group (P value 0.0041). 4. Conclusion. ACL injuries with MCL involvement led to an increase in anterior medial rotary laxity and this is more evident in patients where deep MCL fibres are involved. The Feagin-Thomas test appears to be sensitive in detecting differences in AMRI and should be considered when performing comprehensive clinical knee examination.

Purpouse. We hypothesized that patients receiving a medial collagen meniscus implant (MCMI) would show better clinical, radiograpich and Magnetic Resonanace Imaging (MRI) outcomes than patients treated with partial medial meniscectomy (PMM) at minimum 10 year FU. Material and Methods. Thirty-three non-randomized patients (males, mean age 40 years) were enrolled in the study to receive a MCMI (17 patients) or as control treated with a PMM (16 patients). All of them were clinically evaluated at time zero, 5 and minimum 10 years after surgery (mean FU 133 months, range 120–145) by Lysholm, VAS for pain, objective IKDC knee form and Tegner activity level. SF-36 score was performed pre-operatively and at final FU. Bilateral weight-bearing XRays were executed at time zero and at final FU. Minimum 10 years FU MRI images were compared with collected pre-operative MRI images by means of Yulish score. Genovese score was also used to evalute MCMI MRI survivorship. Results. MCMI group showed significantly lower VAS for pain (p = 0.0091), higher objective IKDC (p = 0.0026), Teger index (p = 0.0259) and SF-36 (p = 0.0259 for PHI and p = 0.0036 for MHI) scores compared with PMM group at minimum 10 year FU. Radiographic evaluation showed a significantly lower medial joint line height (p = 0.0002) and side-to-side difference (p = 0.0003) narrowing in MCMI group respect to PMM group at final FU. Discussion. Improvements in pain relief, activity level, objective IKDC score and joint-line preservation are detectable with the use of MCMI at a minimum 10 year FU. On the authors knowledge this is the first long-term controlled trial regarding this device, and our findings confirmed the mid-term good results achieved by Rodkey et al (1). Conclusions. This data support the use of meniscal scaffolds to treat irreparable partial meniscal lesions. Long-term prospective randomized controlled trials on a larger population are necessary to determine the extent and duration of the benefits observed

Introduction. Medial column insufficiency in patients with painful acquired flatfoot can be difficult to appreciate. The reverse Coleman block test is used in this study to predict medial column instability. Methods. Patients who underwent a procedure for medial column insufficiency with use of the reverse Coleman block test pre-operatively were investigated. Weight bearing radiographs were used to determine the joints in the medial column contributing to the deformity and also to estimate the angle which the first ray must be depressed to re-establish hindfoot neutrality. The reverse Coleman block test corrects a mobile valgus heel to a neutral position by placing a block, of appropriate height, under the first metatarsal head. With the heel in neutral and the relative forefoot supination compensated the foot returns to a neutral anatomic position. Gender, age, complications and radiological outcomes were investigated. Results. Over the last three years 25 medial column procedures were performed for painful insufficiency on 17 females and five males by the senior author. Three patients underwent staged bilateral procedures. The average age was 62 years old. Three feet had been on operated on the medial column previously. The pre-operative weight bearing lateral radiographs showed instability in the medial column greater than 5° in 12 cases. With the reverse Coleman block test instability was seen in 25 cases and the deformity increased from an average of 7° (range 0° to 25°) to 14° (range 5° to 30°). Post-operative weight bearing radiographs, with fusion of the unstable joint, the average medial column alignment was 1° (range −10° to 10°). Three patients developed superficial infections requiring oral antibiotics for treatment. One patient had a non-union requiring revision surgery. Discussion. The reverse Coleman block test revealed instability in 13 out of 27 cases not seen with simple weight bearing lateral radiographs. The test also on average doubled the size of any deformity seen. This aided pre-operative planning to predict the scale of deformity correction required. Conclusion. The reverse Coleman block test is a useful test to determine medial column insufficiency and assist with pre-operative planning

Between 1992 and 2000, 57 patients with 57 isolated fractures of the medial malleolus were treated conservatively by immobilisation in a cast. The results were assessed by examination, radiography and completion of the short form-36 questionnaire and American Orthopaedic Foot and Ankle Society ankle-hindfoot score. Of the 57 fractures 55 healed without further treatment. The mean combined dorsi- and plantar flexion was 52.3° (25° to 82°) and the mean short form-36 and American Orthopaedic Foot and Ankle Society scores 48.1 (28 to 60) and 89.8 (69 to 100), respectively. At review there was no evidence of medial instability, dermatological complications, malalignment of the mortise or of post-traumatic arthritis. Isolated fractures of the medial malleolus can obtain high rates of union and good functional results with conservative treatment. Operation should be reserved for bi- or trimalleolar fractures, open fractures, injuries which compromise the skin or those involving the plafond or for patients who develop painful nonunion

After a severe ankle sprain the incidence of residual complaints, particularly on the medial side of the joint, is high. We studied a consecutive series of 30 patients who had operative repair of acute ruptures of lateral ligaments. During operation, arthroscopy revealed a fresh injury to the articular cartilage in 20 ankles, in 19 at the tip and/or anterior distal part of the medial malleolus as well as on the opposite medial facet of the talus. In six patients, a loose piece of articular cartilage was found. We conclude that in patients with a rupture of one or more of the lateral ankle ligaments after an inversion injury, an impingement occurs between the medial malleolus and the medial facet of the talus. Patients with a lesion of the lateral ankle ligament caused by a high-velocity injury (a faulty landing during jumping or running) had a higher incidence of macroscopic cartilage damage (p < 0.01), medially-located pressure pain (p = 0.06) and medially-located complaints at one-year follow-up (p = 0.02) than those with a low-velocity injury (a stumble)

We aimed to analyse complication rates following medial opening-wedge high tibial osteotomy (OWHTO) for knee OA. A regional retrospective cohort study of all patients who underwent HTO for isolated medial compartment knee OA from 2003–2013. 115 OWHTO were performed. Mean age = 47 (95%CI 46–48). Mean BMI = 29.1 (95%CI 28.1–30.1). Implants used: 72% (n=83) Tomofix, 21% (n=24) Puddu plate, 7% (n=8) Orthofix Grafts used: 30% (n=35) autologous, 35% (n=40) artificial and 35% (n=40) no graft. 25% (n=29) of patients suffered 36 complications. Complications included minor wound infection 9.6%, major wound infection 3.5%, metalwork irritation necessitating plate removal 7%, non-union requiring revision 4.3%, vascular injury 1.7%, compartment syndrome 0.9%, and other minor complications 4%. Apparent higher rates of non-union occurred with the Puddu plate (8.3%) relative to Tomofix (3.6%) but was not statistically significant. No other significant differences existed in complication rates relative to implant type, bone graft used, patient age or BMI. Serious complications following HTO appear rare. The Tomofix has an apparent lower rate of non-union compared to older implants but greater numbers are required to determine significance. There is no significant difference in union rate relative to whether autologous graft, artificial graft or no graft is used

Background. Medial opening-wedge high tibial osteotomy is one of the common surgical procedures in treatment of knee deformities. Many methods have been proposed to fill the medial side osseous gap. The results of using allograft as void filler compared to iliac crest autograft has not been subject to a randomized clinical trial. The purpose of this study was to examine the results of medial opening-wedge high tibial osteotomy using iliac crest allograft as compared to iliac crest autograft. Materials & Methods. Forty-six patients with genovarum deformity were enrolled based on specific inclusion and exclusion criteria and were randomly assigned into two groups. Medial opening-wedge high tibial osteotomy was done using iliac crest allograft (23 patients) or autograft (23 patients) and the osteotomy site was internally fixed using proximal tibial T-plate. All patients were followed-up to 12 months after surgery. Anatomical indices of proximal tibia, complications of treatment, and functional outcome (using WOMAC osteoarthritis index) were assessed for both groups. Results. The amount of correction (degrees), recurrence of the deformity and loss of correction and time to clinical or radiologic union were similar in both groups with no statistically significant difference. Duration of operation was significantly less in allograft group (66.6±3.6 versus 52.9±5.3 minutes, p<0.001). Incidence of surgical site infection did not significantly differ in two groups. No nonunion or delayed union was encountered in either group. Some patients reported more intense postoperative pain in iliac graft harvest site than tibial osteotomy site. Patients in both groups had statistically significant improvement in WOMAC index postoperatively (with no statistically significant difference between groups). Conclusions. According to the results of this study, iliac crest allograft may be safely used in medial opening-wedge high tibial osteotomy with comparable efficacy to iliac crest autograft in patients who do not accept the morbidity of autograft harvest

Background. Acquired flatfoot deformity goes ahead with a partial or complete rupture and thus insufficiency of the tibialis posterior tendon. We present the results of flexor digitorum longus transfer and medial displacement calcaneal osteotomy to reconstruct the acquired deformity. Material & Methods. Twenty two patients (24 feet) with an average age of 58 (36–75) years were operated on for acquired flexible flatfoot deformity. Two patients had a bilateral procedure. Patients were seen pre-and postoperatively in order to evaluate following parameters: AOFAS hindfoot score, visual analogue scale for pain (0–10), the tarsometatarsal angle on lateral and ap standing x-rays, the cuneiform heights and talocalcaneal angle on lateral standing x-rays and subjective postoperative satisfaction score (1-worst to 5-best). Average time of follow-up was 24.7 months (12–48). Results. The AOFAS hindfoot score could be increased from 46.4 to 89.5 points, the visual analogue scale for pain decreased from 6.6 to 1.1. The average satisfaction score was 4.5 points with one patient scoring 2 and another one scoring 3. All the other patients scored either 4 or 5. All radiological parameters could be improved. Following complications were seen: one recurrence, two patients with irritation of the sural nerve, one patient with hypesthesia of the big toe. The calcaneal screws had to be removed in 3 patients. Conclusion. Flexor digitorum longus transfer together with medial displacement calcaneal osteotomy gave satisfactory results for the treatment of acquired flatfoot deformity. All radiologic parameters were improved

Introduction. Sternoclavicular dislocations are well-known adult injuries. The same traumatism causes growth-plate fracture of the medial clavicle in children and young adults. At this location, the emergence of the secondary ossification center and its bony fusion are late. We report the results of 20 cases hospitalized in the Toulouse University Hospital Center that were treated surgically. Materials & Methods. 20 patients were treated between 1993 and 2007, 17 boys and 3 girls, 16 years old (6–20). The traumatism was always violent (rugby 75%). Two physeal fractures were anteriorly displaced, and 18 posteriorly. The follow-up is 64 month (8–174). Clinical, radiographic and therapeutic characteristics were assessed. The long-term results were analysed with: an algo-functional scale (Oxford shoulder score), the subjective Constant score, a functional disability scale (Shoulder simple test), a quality of life scale (DASH), and global indicators (SANE and global satisfaction). Results. all the patients were symptomatic before surgery: pains, oedema and partial functional impotence. Only 2 dysphagia, 1 dyspnea and 1 venous circulation alteration were observed. The first clinical and radiological examination, before CT scan, didn't diagnose the injury in 8 cases. The CT scan were realized for all the patients: it diagnosed the physeal fracture and showed 4 cases of vascular or respiratory compressions. There were 5 attempts of closed reduction, without success: all the patients were surgically-treated. The open reduction were completed by pinning (12 cases) or cerclage with absorbable suture (3 cases). Per-operatory findings lead to realize costo-clavicular repair plasties with the sub-clavicular muscle (3 cases) and/or capsular-ligamentous-perosteal selective plasties (13 cases). Two cases of broken Kirschner wires were noticed, without migration. Functional outcomes are largely good or excellent: STT 11,74/12 (10–12)–OSS 12,95/60 (12–19)–DASH 2,07/100 (0–17,6)–SANE 93,16% (60–100). Discussion and Conclusion. we present the largest case series in the literature. CT scanner is the essential element of the diagnostic process and may allow the distinction between true sterno-clavicular dislocation and displaced physeal fractures. This distinction is difficult at younger ages and is facilitated by the progression of ossification. Very good results were obtained, but classical pitfalls of treatment were found: instability after closed reduction, broken K-wires, recurrent anterior instability, inesthetic scars

The purpose of this study is to analyze what kind of pattern of change in each posterior femoral condyle allows for a greater degree of flexion after total knee arthroplasty (TKA). The flexion angle was assessed pre-operatively, and at 12 months after the surgery in 98 patients (106 knees) who underwent consecutive TKA. We used a quantitative 3 dimensional technique using computed tomography for the assessment of changes in both the medial and lateral femoral condylar offset. There were no significant correlation between changes of each posterior condylar offset and post flexion angle (medial condyle; R=−0.038, p=0.70, lateral condyle; R=−0.090, p=0.36). There were no significant differences between changing patterns and increase rate of flexion (p=0.443). Additionally there were no significant differences between changing patterns and increase of flexion angle (p=0.593). Changes of each posterior condylar offset were no correlation to knee flexion after TKA in the current design prosthesis

Joint registries report that 25–40% of UKR revisions are performed for pain. Proximal tibial strain and microdamage are possible causes of this “unexplained” pain. The aim of this study was to examine the effect of UKR implant design and material on proximal tibial cortical strain and cancellous microdamage. Composite Sawbone tibias were implanted with cemented UKR components: 5 fixed bearing all-polyethylene (FB-AP), 5 fixed bearing metal backed (FB-MB), and 5 mobile bearing metal backed implants (MB-MB). Five intact tibias were used as controls. Tibias were loaded in 500N increments to 2500N. Cortical surface strain was measured using digital image correlation (DIC). Cancellous microdamage was measured using acoustic emission (AE), a technique which detects elastic waves produced by the rapid release of energy during microdamage events. DIC showed significant differences in anteromedial cortical strain between implants at 1500N and 2500N in the proximal 10mm only (p<0.001) with strain shielding in metal backed implants. AE showed significant differences in cancellous microdamage (AE hits), between implants at all loads (p=0.001). FB-AP implants displayed significantly more hits at all loads than both controls and metal backed implants (p<0.001). FB-AP implants also differed significantly by displaying AE hits on unloading (p=0.01), reflecting a lack of implant stiffness. Compared to controls, the FB-AP implant displayed 15x the total AE hits, the FB-MB 6x and the MB-MB 2.7x. All-polyethylene medial UKR implants are associated with greater cancellous bone microdamage than metal backed implants even at low loads

The aims of this study were to undertake a prospective randomised trial to compare functional outcome, and range of motion after treatment of medial collateral ligament injuries by either early unprotected mobilisation or mobilisation with a hinged brace. Patients were randomised into either unprotected mobilisation or mobilisation with a hinged brace. Assessments occurred at 2 weeks, 6 weeks, 3 months and 6 months. Outcome measures included validated questionnaires (International Knee Documentation Committee and Knee Injury and Osteoarthritis Outcome Score scores), range of motion measurements and strength testing. Eighty six patients (mean age 30.4) were recruited. There were 53 men and 33 women. The mode of injury was sport in 56 patients (65%) with football, rugby and skiing being the most common types of sport involved. The mean time to return to full weight bearing was 3 weeks in both groups. The mean time to return to work was 4.6 weeks in the braced group and 4.1 weeks in the non-braced group (p=0.79). Return to running was at a mean of 14.3 weeks in the braced group and 12.8 weeks in the non-braced group (p=0.64). Return to full sport was 22 weeks in the braced group and 22.1 weeks in the non-braced group (p=0.99). There was no significant difference in range of movement or pain scores between the two groups at 2,6,12 and 24 weeks. The use of a hinged knee brace does not influence recovery after a medial collateral injury

To our knowledge in medial unicompartmental knee arthroplasty (UKA) no study has specifically assessed the difference in outcome between matched gender groups. Previous unmatched gender studies have indicated more favourable results for women.

Method

2 groups of 40 of either sex was determined sufficient power for significant difference. These consecutively were matched with both the pre-operative clinical and radiological findings. Minimum follow up of 2 years, mean follow-up 5.9 years. Mean age at operation was 71 years.

Results

In both groups, the mean IKS knee and function scores improved significantly (p< 0.001) post operatively. There were no significant differences were between the 2 groups. In both groups mean preoperative flexion was 130 degrees and remained unchanged at final follow-up. No significant differences in preoperative and postoperative axial alignment and in the number of radiolucent lines, between groups.

With component size used there was a significant difference (p < 0.001) between the 2 groups. However the size of the femoral or tibial implant used was significantly related (p< 0.001) to patient height for both sexes. Radiolucent lines were more frequent on the tibial component, but were considered stable with none progressing. No revisions for component failure. 1 patient in each group developed lateral compartment degenerative change.

Male group; one conversion to TKA for undiagnosed pain, three patients underwent reoperation without changing the implant. Female group; no implants were revised, and two patients required a reoperation. Kaplan-Meier 5-year survival rate of 93.46% (84.8; 100) for men and100% for women. The survival rate difference is not significant (p=0.28).

We retrospectively analysed the clinical results of 30 patients with injuries of the sternoclavicular joint at a minimum of 12 months’ follow-up. A closed reduction was attempted in 14 cases. It was successful in only five of ten dislocations, and failed in all four epiphyseal disruptions. A total of 25 patients underwent surgical reduction, in 18 cases in conjunction with a stabilisation procedure.

At a mean follow-up of 60 months, four patients were lost to follow-up. The functional results in the remainder were satisfactory, and 18 patients were able to resume their usual sports activity at the same level. There was no statistically significant difference between epiphyseal disruption and sternoclavicular dislocation (p > 0.05), but the functional scores (Simple Shoulder Test, Disability of Arm, Shoulder, Hand, and Constant scores) were better when an associated stabilisation procedure had been performed rather than reduction alone (p = 0.05, p = 0.04 and p = 0.07, respectively).

We recommend meticulous pre-operative clinical assessment with CT scans. In sternoclavicular dislocation managed within the first 48 hours and with no sign of mediastinal complication, a closed reduction can be attempted, although this was unsuccessful in half of our cases. A control CT scan is mandatory. In all other cases, and particularly if epiphyseal disruption is suspected, we recommend open reduction with a stabilisation procedure by costaclavicular cerclage or tenodesis. The use of a Kirschner wire should be avoided.

Stable Weber B fractures are typically treated non-operatively without complications but require close monitoring due to concerns over potential medial deltoid ligament injuries and the risk of delayed talar shift. Following recent evidence suggesting this is unlikely, a functional protocol with early weight bearing was introduced at Glasgow Royal Infirmary (GRI) following a pilot audit. This study aims to evaluate the risk of delayed talar shift in isolated Weber B fractures managed with functional bracing and early weight-bearing, particularly if signs of medial ligament injury are present. We conducted a retrospective review of 148 patients with isolated Weber B fractures without talar shift at presentation that were reviewed at the virtual fracture clinic at our institution between July 2019 and June 2020. The primary outcome was the incidence of delayed talar shift. Secondary outcomes were other complications and adherence to protocol. 48 patients had medial signs present and of these 1 (2%) showed possible talar shift on X-rays at 4 weeks, and was kept under review. This patient had a normal medial clear space at 3 months. No patients with medial signs not documented (n=19) or not present (n=81) had delayed talar shift. 10% of patients (n=15) had at least 1 complication: delayed union (n=2); non-union (n=3); ongoing pain (n=14). Functional bracing with early weight-bearing is a safe, effective protocol for managing isolated Weber B fractures without initial talar shift. This study concludes that the risk of delayed talar shift is low in all patients, with or without medial signs

The surgical care of extra-articular distal tibial fractures remains controversial. This study looks at the radiological outcomes of distal tibial fractures treated with either a direct medial or anterolateral plate, with or without plating of the fibula, to assess the outcome and complications associated with these 2 approaches. This is a retrospective review of 80 patients with distal tibial extra-articular fractures, treated with an open reduction and plating, between 2008 and 2019 at Glasgow Royal Infirmary. Case notes and x-rays were reviewed. Of those tibial fractures fixed with only a medial plate, 78% united (28/36), 5% (2/36) had a non-union and 17% (6/36) a malunion. In the group treated with a combination of medial tibial and fibular plating, the figures were; 71% (15/21), 19% (4/21) and 10% (2/21). However, in the group treated with anterolateral plating of the tibia alone, only 53% (8/15) united, with a 20% (3/15) non-union and 13% (2/15) malunion rate. Additionally in this group, there were 2 patients (13%) with loss of fracture reduction within the first two months of fracture fixation, requiring revision surgery. Interestingly, of the 8 patients treated with anterolateral tibial and fibular plating, 88% (7/8) showed full union and only one (12%) had a non-union, with no malunions is this group. It would appear that medial tibial and a combination of medial tibial and fibular plating, have superior outcomes compared to anterolateral plating. Results suggest, if anterolateral plating is done, this should be augmented by fixation of the fibular fracture as well

Introduction. Osteochondral lesions (OCLs) of the talus are a challenging and increasingly recognized problem in chronic ankle pain. Many novel techniques exist to attempt to treat this challenging entity. Difficulties associated with treating OCLs include lesion location, size, chronicity, and problems associated with potential graft harvest sites. Matrix associated stem cell transplantation (MAST) is one such treatment described for larger lesions >15mm2 or failed alternative therapies. This cohort study describes a medium-term review of the outcomes of talar lesions treated with MAST. Methods. A review of all patients treated with MAST by a single surgeon was conducted. Preoperative radiographs, MRIs and FAOS outcome questionnaire scores were conducted. Intraoperative classification was undertaken to correlate with imaging. Postoperative outcomes included FAOS scores, return to sport, revision surgery/failure of treatment and progression to arthritis/fusion surgery. Results. 58 MAST procedures in 57 patients were identified in this cohort. The mean follow up was 5 years. There were 20 females and37males, with a mean age of 37 years (SD 9.1). 22 patients had lateral OCLS were and 35 patients had medial OCLs. Of this cohort 32patients had previous surgery and 25 had this procedure as a primary event. 15 patients had one failed previous surgery, 9 patients had two, four patients had three previous surgeries and three patients had four previous surgeries. 12 patients had corrective or realignment procedures at the time of surgery. In terms of complications 3 patients of this cohort went on to have an ankle fusion and two of these had medial malleolar metal work taken out prior to this, 5 patients had additional procedures for arthrofibrotic debridements, 1 patient had a repeat MAST procedure, 1 additional patients had removal of medial malleolar osteotomy screws for pain at the osteotomy site, there were 2 wound complications one related to the ankle and one related to pain at the iliac crest donor site. Conclusion. MAST has demonstrated positive results in lesions which prove challenging to treat, even in a “ failed microfracture” cohort. RCT still lacking in field of orthobiologics for MAST. Longer term follow up required to evaluate durability

Aims. Several previously identified patient-, injury-, and treatment-related factors are associated with the development of nonunion in distal femur fractures. However, the predictive value of these factors is not well defined. We aimed to assess the predictive ability of previously identified risk factors in the development of nonunion leading to secondary surgery in distal femur fractures. Methods. We conducted a retrospective cohort study of adult patients with traumatic distal femur fracture treated with lateral locking plate between 2009 and 2018. The patients who underwent secondary surgery due to fracture healing problem or plate failure were considered having nonunion. Background knowledge of risk factors of distal femur fracture nonunion based on previous literature was used to form an initial set of variables. A logistic regression model was used with previously identified patient- and injury-related variables (age, sex, BMI, diabetes, smoking, periprosthetic fracture, open fracture, trauma energy, fracture zone length, fracture comminution, medial side comminution) in the first analysis and with treatment-related variables (different surgeon-controlled factors, e.g. plate length, screw placement, and proximal fixation) in the second analysis to predict the nonunion leading to secondary surgery in distal femur fractures. Results. We were able to include 299 fractures in 291 patients. Altogether, 31/299 fractures (10%) developed nonunion. In the first analysis, pseudo-R. 2. was 0.27 and area under the receiver operating characteristic curve (AUC) was 0.81. BMI was the most important variable in the prediction. In the second analysis, pseudo-R. 2. was 0.06 and AUC was 0.67. Plate length was the most important variable in the prediction. Conclusion. The model including patient- and injury-related factors had moderate fit and predictive ability in the prediction of distal femur fracture nonunion leading to secondary surgery. BMI was the most important variable in prediction of nonunion. Surgeon-controlled factors had a minor role in prediction of nonunion. Cite this article: Bone Jt Open 2023;4(8):584–593
