Introduction. Comminuted mid-foot fractures are uncommon. Maintenance of the length and alignment of the medial column, with restoration of articular surface congruity, is associated with improved outcomes. Conventional surgery has utilised open or closed reduction with K-wire fixation, percutaneous techniques, ORIF, external fixation or a combination of these methods. In 2003 temporary bridge plating of the medial column was described to reconstruct and stabilise the medial column. The added advantage of locking plates is the use of angle-stable fixation. We present our experience with temporary locking plates in complex mid-foot fractures. Materials and methods. Prospective audit database of 12 patients over a 6 year period (2003-2009). 5 males 7 females mean age 41.9. Mechanism of injury: 11 high-energy injuries (6 falls from height, 5 RTCs), 1 low energy injury. Fracture type: All involved the medial column - 12 fracture dislocations of the medial column. 4 concomitant injuries to the lateral column. All underwent ORIF, realignment, and stabilisation with locking plates across the mid-foot. Results. Median length of time to plate removal: 3 months (range 2-6). Prior to removal of the metalwork, there was no loss of reduction, no infections, and no implant breakage. 10 out of 12 required plate removal at 3 months. Long-term follow-up (Mean 12.4 months, range 4-32): 11 have minimal symptoms of swelling or discomfort from the midfoot which does not restrict their ADLs, whilst 1 patient developed post-traumatic arthritis with medial arch collapse. No secondary procedures following plate removal. The two patients with the plate in-situ were asymptomatic with regards to the metalwork at final follow-up. Conclusion. Locking plates provide adequate stabilisation following open reduction and internal fixation of complex and unstable midfoot fracture dislocations. However, the majority will require removal of the metalwork. Following removal of the metalwork, satisfactory length and alignment, and stability of the midfoot, is maintained

Aims

Fractures of the navicular can occur in isolation but, owing to the intimate anatomical and biomechanical relationships, are often associated with other injuries to the neighbouring bones and joints in the foot. As a result, they can lead to long-term morbidity and poor function. Our aim in this study was to identify patterns of injury in a new classification system of traumatic fractures of the navicular, with consideration being given to the commonly associated injuries to the midfoot.

Patients and Methods

We undertook a retrospective review of 285 consecutive patients presenting over an eight- year period with a fracture of the navicular. Five common patterns of injury were identified and classified according to the radiological features. Type 1 fractures are dorsal avulsion injuries related to the capsule of the talonavicular joint. Type 2 fractures are isolated avulsion injuries to the tuberosity of the navicular. Type 3 fractures are a variant of tarsometatarsal fracture/dislocations creating instability of the medial ray. Type 4 fractures involve the body of the navicular with no associated injury to the lateral column and type 5 fractures occur in conjunction with disruption of the midtarsal joint with crushing of the medial or lateral, or both, columns of the foot.

We performed a systematic review and meta-analysis of modern total ankle replacements (TARs) to determine the survivorship, outcome, complications, radiological findings and range of movement, in patients with end-stage osteoarthritis (OA) of the ankle who undergo this procedure. We used the methodology of the Cochrane Collaboration, which uses risk of bias profiling to assess the quality of papers in favour of a domain-based approach. Continuous outcome scores were pooled across studies using the generic inverse variance method and the random-effects model was used to incorporate clinical and methodological heterogeneity. We included 58 papers (7942 TARs) with an interobserver reliability (Kappa) for selection, performance, attrition, detection and reporting bias of between 0.83 and 0.98. The overall survivorship was 89% at ten years with an annual failure rate of 1.2% (95% confidence interval (CI) 0.7 to 1.6). The mean American Orthopaedic Foot and Ankle Society score changed from 40 (95% CI 36 to 43) pre-operatively to 80 (95% CI 76 to 84) at a mean follow-up of 8.2 years (7 to 10) (p < 0.01). Radiolucencies were identified in up to 23% of TARs after a mean of 4.4 years (2.3 to 9.6). The mean total range of movement improved from 23° (95% CI 19 to 26) to 34° (95% CI 26 to 41) (p = 0.01).

Our study demonstrates that TAR has a positive impact on patients’ lives, with benefits lasting ten years, as judged by improvement in pain and function, as well as improved gait and increased range of movement. However, the quality of evidence is weak and fraught with biases and high quality randomised controlled trials are required to compare TAR with other forms of treatment such as fusion.

A total of 80 patients with an acute rupture of tendo Achillis were randomised to operative repair using an open technique (39 patients) or non-operative treatment in a cast (41 patients). Patients were followed up for one year. Outcome measures included clinical complications, range of movement of the ankle, the Short Musculoskeletal Function Assessment (SMFA), and muscle function dynamometry evaluating dorsiflexion and plantar flexion of the ankle. The primary outcome measure was muscle dynamometry.

Re-rupture occurred in two of 37 patients (5%) in the operative group and four of 39 (10%) in the non-operative group, which was not statistically significant (p = 0.68). There was a slightly greater range of plantar flexion and dorsiflexion of the ankle in the operative group at three months which was not statistically significant, but at four and six months the range of dorsiflexion was better in the non-operative group, although this did not reach statistically significance either. After 12 weeks the peak torque difference of plantar flexion compared with the normal side was less in the operative than the non-operative group (47% vs 61%, respectively, p < 0.005). The difference declined to 26% and 30% at 26 weeks and 20% and 25% at 52 weeks, respectively. The difference in dorsiflexion peak torque from the normal side was less than 10% by 26 weeks in both groups, with no significant differences. The mean SMFA scores were significantly better in the operative group than the non-operative group at three months (15 vs 20, respectively, p < 0.03). No significant differences were observed after this, and at one year the scores were similar in both groups.

We were unable to show a convincing functional benefit from surgery for patients with an acute rupture of the tendo Achillis compared with conservative treatment in plaster.

We investigated the clinical and radiological outcome after unilateral fracture of the lateral process of the talus in 23 snowboarders with a mean follow-up of 3.5 years (12 to 76 months). In this consecutive cohort study both operative and non-operative cases were considered.

The mean American Orthopaedic Foot and Ankle Society hindfoot score was 94 (82 to 100). The non-operative group of seven with a minimally-displaced fracture scored higher (98 points) than the operative group of 16 with displaced or unstable fractures (93 points). In 88% of operative cases, significant concomitant hindfoot injuries were found at operation. All but eight (35%) patients (six operative and two non-operative) regained their pre-injury level of sporting activity. Subtalar osteoarthritis was present in nine (45%) of the 20 patients available for radiological review, including one late-diagnosed non-operative case and eight operative cases with associated injuries or fracture comminution.

The outcome after fracture of the lateral process of the talus in snowboarders is favourable provided an early diagnosis is made and adequate treatment, which is related to the degree of displacement and associated injuries, is undertaken.
