AIMS: To develop a reliable and effective radiological score to assess the healing of isolated ulnar shaft fractures (IUSF), the Radiographic Union Score for Ulna fractures (RUSU).METHODS: Initially, 20 patients with radiographs six weeks following a non-operatively managed ulnar shaft fracture were selected and scored by three blinded observers. After intraclass correlation (ICC) analysis, a second group of 54 patients with radiographs six weeks after injury (18 who developed a nonunion and 36 who united) were scored by the same observers.RESULTS: In the initial study, interobserver and intraobserver ICC were 0.89 and 0.93, respectively. In the validation study, the interobserver ICC was 0.85. The median score for patients who united was significantly higher than those who developed a nonunion (11 vs. 7, p CONCLUSION: The RUSU shows good interobserver and intraobserver reliability and is effective in identifying patients at risk of nonunion six weeks after fracture. This tool requires external validation but may enhance the management of patients with isolated ulnar shaft fractures.

The aim was to compare surgical and nonsurgical management for adults with humeral shaft fractures in terms of patient-reported upper limb function, health-related quality of life, radiographic outcomes, and complications.MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature, PubMed, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, International Clinical Trials Registry, and OpenGrey (Repository for Grey Literature in Europe) were searched in September 2021. All published prospective randomized trials comparing surgical and nonsurgical management of humeral shaft fractures in adults were included. Of 715 studies identified, five were included in the systematic review and four in the meta-analysis. Data were extracted by two independent reviewers according to the Preferred Reporting Items for Systematic Review and Meta-Analysis statement. Methodological quality was assessed using the revised Cochrane risk-of-bias tool for randomized trials. Pooled data were analyzed using a random-effects model.The meta-analysis comprised 292 patients (mean age 41 [18 to 83] years, 67% male). Surgery was associated with superior Disabilities of the Arm, Shoulder and Hand (DASH) and Constant-Murley scores at 6 months (mean DASH difference 7.6, P = 0.01; mean Constant-Murley difference 8.0, P = 0.003), but there was no difference at 1 year (DASH, P = 0.30; Constant-Murley, P = 0.33). No differences in health-related quality of life or pain scores were found. Surgery was associated with a lower risk of nonunion (0.7% versus 15.7%; odds ratio [OR] 0.13, P = 0.004). The number needed to treat with surgery to avoid one nonunion was 7. Surgery was associated with a higher risk of transient radial nerve palsy (17.4% versus 0.7%; OR 8.23, P = 0.01) but not infection (OR 3.57, P = 0.13). Surgery was also associated with a lower risk of reintervention (1.4% versus 19.3%; OR 0.14, P = 0.04).Surgery may confer an early functional advantage to adults with humeral shaft fractures, but this is not sustained beyond 6 months. The lower risk of nonunion should be balanced against the higher risk of transient radial nerve palsy.Level I.

Background Whilst the lateral malleolus appears to be crucial in controlling anatomical reduction of the talus, the role of the medial malleolus is less clear. Medial sided complications including infection, damage to local structures and symptomatic hardware are not without morbidity. This study compares the outcomes of patients with bimalleolar or trimalleolar ankle fractures who underwent fibular nail stabilisation with or without medial malleolar fixation. Methods From a prospective single-centre trauma database, we identified 342 patients over a nine-year period who underwent fibular nail insertion to stabilise a bimalleolar or trimalleolar ankle fracture. Isolated lateral malleolar fractures were excluded. Demographic data, clinical outcomes, radiographic evaluation, return to work and sport, and patient reported outcomes, including Olerud-Molander Ankle Score (OMAS), EuroQol-5D (EQ-5D) and Manchester-Oxford Foot Questionnaire (MOXFQ) were collected. Results This study included 247 patients with a mean age of 66.7 years (range, 25–96 years), of whom 200 were female (81%). Medial malleolar fixation was not performed in 54 cases (22%). There was no significant difference between groups with respect to failure of fixation (p = 0.634) or loss of talar reduction (p = 0.157). No patient required surgery for a symptomatic medial malleolar non-union. Medial sided complications occurred in 32 (16%) of the fixation group, of whom 20 (10%) required further surgery. At a mean mid-term follow-up of 4.8 years (range, 8 months – 9 years) there was no significant difference between the non-fixation and fixation groups with respect to the median OMAS (85 vs 80; p = 0.885) or median EQ-5D (0.80 vs 0.81; p = 0.846). Patient satisfaction was not significantly different between the two groups (85/100 vs 87/100; p = 0.410). Conclusion Non-operative management of the medial malleolar component of an unstable ankle fracture treated with a fibular nail may reduce the rate of post-operative complications without compromising the patient reported outcome.

This chapter summarizes the seminal literature relating to factors that increase the risk of distal radius fracture instability and secondary displacement. The currently available evidence indicates that increasing age and the presence of dorsal comminution are strongly predictive of secondary displacement. Several other risk factors have also been proposed and are in common use in clinical practice, but, perhaps surprisingly, none has been shown conclusively to be predictive of displacement. A classification or clinical prediction model would be useful for risk stratification and allow management to be informed and tailored to individual patient and injury factors.

Objectives To identify risk factors for fixation failure, report patient outcomes, and advise on modifications to the surgical technique for fibula nail stabilization of unstable ankle fractures. Design Retrospective review. Setting Academic orthopaedic trauma unit. Patients All 342 patients were identified retrospectively from a prospectively collected single-center trauma database over a 9-year period. Intervention Unstable ankle fractures managed surgically with a fibula nail. Main outcome measurements The primary short-term outcome was failure, defined as any case that required revision surgery because of an inadequate mechanical construct. The mid-term outcomes included the Olerud-Molander Ankle Score and the Manchester-Oxford Foot Questionnaire. Results Twenty failures occurred (6%), of which 7 (2%) were due to device failure and 13 (4%) due to surgeon error. Of the surgeon errors, 8 consisted of inappropriate weight-bearing after syndesmotic diastasis, and 5 were due to inadequate fracture reduction or poor nail placement. Proximal locking screw (PLS) pull-out was the cause of all device failures. Positioning the PLS >20 mm above the plafond significantly increased failure risk (P = 0.003). At a mean follow-up of 5.1 years (range, 8 months-8 years) the median Olerud-Molander Ankle Score and Manchester-Oxford Foot Questionnaire were 80 (interquartile range, 45) and 10.94 (interquartile range, 44.00), respectively. Patient outcome was not negatively affected by the requirement for revision surgery. Conclusions The fibula nail offers secure fixation and good patient-reported outcomes for unstable ankle fractures. Appropriate postoperative management and surgical technique, including careful placement of the PLS, is essential to minimize construct failure risk. Level of evidence Therapeutic Level IV.

PURPOSE: Over 2 million Triathlon single-radius total knee arthroplasties (TKAs) have been implanted worldwide. This study reports the 10-year survival and patient-reported outcome of the Triathlon TKA in a single independent centre.METHODS: From 2006 to 2007, 462 consecutive cruciate-retaining Triathlon TKAs were implanted in 426 patients (median age 69 (21-89), 289 (62.5%) female). Patellae were not routinely resurfaced. Patient-reported outcome measures (SF-12, Oxford Knee Scores (OKS), satisfaction) were assessed preoperatively and at 1, 5 and 10 years when radiographs were reviewed. Forgotten Joint Scores (FJS) were collected at 10 years. Kaplan-Meier survival analysis was performed.RESULTS: At 10-11.6 years, 123 patients (128 TKAs) had died and 8 TKAs were lost to follow-up. There were four aseptic failures (two cases of tibial loosening, two cases of instability) and four septic failures requiring revision. Symptomatic aseptic radiographic loosening was present in three further cases at 11 years. Four (1%) patellae were secondarily resurfaced. OKS score improved by 17.7 ± 9.7 points at 1 year (p CONCLUSION: The Triathlon TKA continues to show excellent longer-term results with high implant survivorship, low rates of aseptic failure, consistently maintained PROMs and excellent patient satisfaction rates of 88% at 10 years.LEVEL OF EVIDENCE: II, Prospective cohort study.
