RESUMEN
BACKGROUND: Corrective fusion for the unstable deformed hind foot and mid foot in Charcot Neuroarthropathy (CN) is quite challenging and is best done in tertiary centres under the supervision of multidisciplinary teams. METHODS: We present a follow up to our initial report with a series of 42 hind foot corrections in 40 patients from a tertiary level teaching hospital in the United Kingdom. The mean patient age was 59 (33-82). 17 patients had type1diabetes mellitus, 23 had type 2. 23 feet in 22 patients had chronic ulceration despite offloading. 17 patients were ASA 2 and 23 were ASA grade 3. All patients had hind foot nail fusion performed through a standard technique by the senior author and managed perioperatively by the multidisciplinary team. RESULTS: At a mean follow up of 42 months (12-99) we achieved 100% limb salvage initially and a 97% fusion rate. One patient with persisting non-union of ankle and subtalar joint with difficulty in bracing has been offered below-knee amputation. We achieved deformity correction in 100% and ulcer healing in 83%. 83% patients are able to mobilize and manage independent activities of daily living. There were 11 patients with one or more complications including metal work failure, infection and ulcer reactivation. There have been nine repeat procedures including one revision fixation and one vascular procedure. CONCLUSION: Single stage corrective fusion for hind foot deformity in CN is an effective procedure when delivered by a skilled multidisciplinary team.

This is a retrospective review of 80 intra-articular calcaneal fractures treated with open reduction and internal fixation by a specialist team under supervision of a single surgeon in a tertiary centre between 2005 and 2014. The fractures were evaluated with plain radiography and computed tomography, and graded using the Eastwood-Atkins classification. A lateral approach was used and all fractures were fixed with calcaneal plates. All patients had clinical and radiological follow-up. Clinical assessment included foot and ankle disability index, SF-36® and Kerr-Atkins scores. The mean follow-up duration was 72 months (range: 12-130 months). The mean age of patients was 49 years (range: 17-73 years). There were three open fractures and eight patients had other injuries. The mean Bohler's angle improved from 6° preoperatively to 26° postoperatively. The mean foot and ankle disability index score was 78.62, the mean SF-36® scores were 45.5 (physical component) and 52.6 (mental component), and the mean Kerr-Atkins score was 72 (range: 36-100). Early complications included one case of screw protrusion in the subtalar joint (which warranted a repeat procedure), one sural nerve injury and one wound breakdown, which healed with non-operative measures. Twelve patients had symptomatic subtalar joint osteoarthritis. Four of these had subtalar fusion. We believe that our strict protocols of patient selection, intraoperative and postoperative management produced long-term results comparable with those in the peer reviewed literature.

INTRODUCTION: Dislocation following total hip replacement continues to be a problem for which no completely satisfactory solution has been found. Several methods have been proposed to reduce the incidence of hip dislocations with varying degrees of success, including elevated rim liners, constrained liners and large diameter bearings. We present our experience with the double mobility acetabular component in patients at high risk of instability. METHODS: This was a retrospective review of 65 primary total hip arthroplasties in 55 patients (15 men, 40 women), performed between October 2005 and November 2009. The majority (80%) of patients had at least two and 26% had at least three risk factors for instability. The mean age was 76 years (range: 44-92 years). The patients were followed up for a mean duration of 60 months (range: 36-85 months). RESULTS: Fourteen patients died and one was lost to follow-up, leaving fifty hips for final assessment. Until the final follow-up appointment, no patients had dislocation and none required revision surgery. The mean Oxford hip score improved from 45.0 to 26.5 (p<0.0001). The mean Merle d'Aubigné pain score improved from 1.4 to 4.9 (p<0.0001), the walking score from 2.3 to 3.1 (p<0.07) and the absolute hip function score from 5.4 to 10.8 (p<0.0001). There were no clinical or radiographic signs of loosening. CONCLUSIONS: The double mobility acetabular component was successful at preventing dislocation during early to medium-term follow-up. However, as data are still lacking with regard to polyethylene wear rates at the additional bearing surface, it would be prudent to restrict the use of this implant to selected patients at high risk of instability.

PURPOSE: This study explored whether a relationship exists between preoperative pinch and power grip strength, and length of hospital stay in patients undergoing hip and knee arthroplasty at a busy UK hospital. We investigated whether handgrip dynamometry could be used preoperatively to identify patients at greater risk of longer inpatient stays. This would allow focussed intervention preoperatively and facilitate predictors of length of stay postoperatively. METHODS: One hundred and sixty-four patients (64 male, 100 female) undergoing lower limb arthroplasty (83 total knee replacement, 81 total hip replacement) were assessed in pre-admission clinic. Average measurements of pinch grip, power grip and grip endurance were taken from each patient using the Jamar hydraulic dynamometer (Jamar, USA). Duration of inpatient stay of each patient was recorded. RESULTS: Average duration of hospital stay was 9.4 days. Both average pinch grip strength and average power grip strength had a significant negative correlation with duration of inpatient stay. Those patients with a pinch grip strength less than 6.3 kg remained an inpatient for an average of 2 days longer than those with a pinch grip greater than 6.3 kg. CONCLUSIONS: This simple test may be highly beneficial preoperatively in identifying those patients likely to require longer inpatient stays and therefore those who would benefit from early nutritional intervention and focussed physiotherapy. It may also facilitate predictors of length of stay postoperatively. We believe this may effect significant cost reductions in the NHS.

We present our experience with a double-mobility acetabular component in 155 consecutive revision total hip replacements in 149 patients undertaken between 2005 and 2009, with particular emphasis on the incidence of further dislocation. The mean age of the patients was 77 years (42 to 89) with 59 males and 90 females. In all, five patients died and seven were lost to follow-up. Indications for revision were aseptic loosening in 113 hips, recurrent instability in 29, peri-prosthetic fracture in 11 and sepsis in two. The mean follow-up was 42 months (18 to 68). Three hips (2%) in three patients dislocated within six weeks of surgery; one of these dislocated again after one year. All three were managed successfully with closed reduction. Two of the three dislocations occurred in patients who had undergone revision for recurrent dislocation. All three were found at revision to have abductor deficiency. There were no dislocations in those revised for either aseptic loosening or sepsis. These results demonstrate a good mid-term outcome for this component. In the 29 patients revised for instability, only two had a further dislocation, both of which were managed by closed reduction.
