The National institute of Health and Clinical Excellence (NICE) guidelines for thromboprophylaxis following lower limb surgery and plastercast immobilisation recommend pharmacological prophylaxis be considered until the cast is removed. These guidelines have been extrapolated from data for hip and knee arthroplasty, and trauma studies. Recent studies have questioned the validity of these guidelines. At Portsmouth, low molecular weight heparin (LMWH) is prescribed for 14 days following surgery in high risk patients. The protocol predates the most recent NICE guidance. We set out to investigate whether this was a safe method of thromboprophylaxis following elective hindfoot surgery. A retrospective audit of all patients undergoing hindfoot surgery between 01/01/10 and 31/12/12 was performed. All patients were immobilised in a POP backslab and prescribed 14 days of LMWH. All patients were reviewed at 2 weeks and converted to a full cast or boot. Immobilisation was continued for between 6 and 12 weeks. A list of all patients who had undergone investigation for deep vein thrombosis at Queen Alexandra hospital from 01/01/10 to 28/03/13 was obtained from the VTE investigation department. The two lists were cross referenced to identify any DVTs occurring following hindfoot surgery and plastercast immobilisation.Introduction:

Hallux valgus is a common condition often leading to significant symptoms. However, its correction has recently been suggested, to be a procedure of limited clinical value. Scarf osteotomy is one of the most commonly performed operations for hallux valgus correction. Although technically demanding, it is powerful in its capacity to correct the hallux valgus deformity and sufficiently robust with internal fixation to allow early weight bearing. We prospectively collected data for consecutive scarf osteotomies between 2008 and 2011. Preoperative and 6 week postoperative assessment was made using radiographic measurements HVA (hallux-valgus angle) and IMA (inter metatarsal angle). We evaluated 130 scarf osteotomies. The mean HVA improved from 29.5 pre-operatively to 12.6 post correction. The mean IMA improved from 12.4 pre-operatively to 8.1 post correction. The AOFAS hallux scores improved from an average of 55 pre op to 79 post operation. The results suggest that hallux valgus correction does have clinical value and that scarf osteotomy is a reproducible procedure, with a generally good to excellent results in the short term.
The purpose of this study was to quantify the effect of BMP 7 and recombinant Human (rh) BMP 2 at stimulating bone formation and bone union in trauma and elective orthopaedic surgery. We retrospectively reviewed the use of BMP 7 and rhBMP 2 at the Queen Alexandra Hospital between 2005 and 2012. The minimum follow up was three months. Inclusion criteria consisted of all patients who had failed to achieve previous surgical bone union and then received either BMP 7 or rhBMP 2 in an attempt to achieve bone union (as part of revision surgery). Patients who have not completed a minimum of three months follow up were excluded. Bone union was defined clinically and radiographically. 17 patients were included (9 elective and 8 trauma patients). 9 patients received BMP2 (8 trauma and 1 elective) and 8 received rhBMP 2 (all elective). The average number of attempted fusions with autogenous bone graft prior to the use of BMP agent in the trauma and elective group was 2 and 3 respectively. The overall union rate following the use of BMP was 94.1%. 1 patient from the BMP 7 group (trauma patient) failed to unite. The union rate with BMP 7 and rhBMP 2 was 88.9% and 100% respectively. Following the use of BMP the average time to union was 117 days (BMP 7 124 days and rhBMP 2 112 days).Methods
Results
We report on the clinical, radiographic and functional outcomes after salvage arthrodesis for complex ankle and hindfoot problems the Portsmouth experience with the Ilizarov ring fixator. We report on 10 patients who underwent ankle and hindfoot (tibio-calcaneal) arthrodeses using an Ilizarov ring fixator between 2006 and 2010. The indications included failed fusion after primary arthrodesis, sepsis complicating internal fixation of fractures, talar avascular necrosis and failed total ankle arthroplasty (TAR). All patients had undergone multiple previous surgeries which had failed. There were 7 males and 3 females in this group. Average age of the patients was 60 (47 years–77 years) Mean follow up was 32 months (6–56 months) BMP 2 (Inductos) was used in three cases. The procedure was combined with a proximal corticotomy and lengthening in 2 patients who had undergone a talectomy and tibio-calcaneal fusion. There were no major complications apart from minor pin site infections requiring oral antibiotics. There were no deep infections, thromo-embolic issues, CRPS, or functional problems on account of limb shortening. Patients were assessed clinically, radiologically and using functional outcome scores EQ50 and AOFAS. Solid arthrodesis was achieved in all but one patient who was subsequently revised with a hindfoot nail. All patients were satisfied with their overall improvement in pain and function.Purpose of the study
Methods and results
We report on the clinical, radiographic and functional outcomes after salvage arthrodesis for complex ankle and hind-foot problems - the Portsmouth experience with the Ilizarov ring fixator. 11 patients underwent ankle and hind-foot (tibio-calcaneal) arthrodeses using an Ilizarov ring fixator between 2006 and 2010. The indications included failed fusion after primary arthrodesis, sepsis complicating internal fixation of fractures, talar avascular necrosis and failed total ankle arthroplasty (TAR). All patients had undergone multiple previous surgeries, which had failed. There were 8 males and 3 females in this group. Average age of the patients was 58 (43 years – 77 years) Mean follow up was 36 months (7 – 60 months). Mean frame time was 24 weeks (15 – 36 weeks). BMP 2 (Inductos) was used in three cases. The procedure was combined with a proximal corticotomy and lengthening in 2 patients who had undergone a talectomy and tibio-calcaneal fusion. There were no major complications apart from minor pin site infections requiring oral antibiotics. There were no deep infections, thromo-embolic issues, CRPS, or functional problems on account of limb shortening. Patients were assessed clinically, radiologically and using functional outcome scores - EQ50 and AOFAS. Solid arthrodesis was achieved in all but one patient who was subsequently revised with a hind-foot nail. All patients were satisfied with their overall improvement in pain and function. We conclude that this is an effective salvage technique for complex ankle and hind-foot problems in patients with impaired healing potential, insufficient bone stock and progressive deformity.
Changes in armour reinforcement of military vehicles have resulted in a changed injury pattern. Injuries which would previously have resulted in amputation are now less severe, and after initial debridement and temporary fixation the foot can now be saved. New patterns of injuries are emerging often as a part of potentially survivable poly-trauma. We describe a small series of these injuries. The techniques and results of late reconstruction are presented. We also discuss specific problems of managing patients with potential contamination with unusual organisms.
CTEV is a difficult condition to treat with chances of recurrence, re-operation rate and over correction. Recent literature based on evidence is favourable with the Ponseti management. The aim of the study was to review our surgical results over a 5-year period using the Cincinnati approach. Children with failure of conservative serial stretching and casting for 6 months underwent open release. The records and radiographs were reviewed retrospectively from 1997–2002. 60 patients were identified with 92 feet undergoing primary sub radical releases using the Cincinnati approach in 40 male and 20 female children. The mean age at surgery was 10 months. 55 patients were idiopathic with 3 syndromal and 2 teratological. Consultants performed >
75% of operations, with k-wire stabilisation done in 46 patients and primary wound closure in 25; the majority of wounds were left open. The timing of plaster change varied, with the majority at 2 weeks. Wound problems occurred in 4 patients (significant in 2). All patients but one wore splints for an average length of 13 months. Complication rate was 20% comprising infection, over- correction and recurrence. Re-operation rate for early recurrence was 12%. Further surgery in the form of tibialis anterior transfer and derotation osteotomy was performed on 15% and 10% of feet respectively. 6 feet in 4 patients showed signs of significant over correction. Wound healing by secondary intention of the Cin-cinnati approach is safe. Results and complications are comparable to other series, but not to the Ponseti non-operative management. Practice is now changed to the latter based on evidence.
Aims: To test the hypothesis that there is a trend to over correction in talipes patients who demonstrate signs of generalised joint laxity. Patients and Methods: 45 patients with an average age of 6.9yrs(3–16) were examined for generalised joint laxity using the Biro score. This gave 65 feet (20 bilateral) for clinical assessment using the podoscope and graded based on Tachdijans flat foot score. Results: The results were assessed and the patients divided into 2 groups depending on whether or not they had joint laxity. This left 19 patients with 26 feet in the non-lax group and 26 patients with 39 feet in the lax group. The 2 groups were then compared to see if there was a difference in flat foot grade. In the non-lax group 2 patients showed evidence of over-correction whereas in the lax group 18 patients(25 feet)were over corrected to some extent. Using the fisher’s exact test there was a significant difference between the 2 groups with a trend towards over correction in those with generalised joint laxity (p=. 002). Conclusion: Based on the findings of this study there is a correlation between generalised joint laxity and over correction in congenital talipes equinovarus.
We wish to report a technique for the reconstruction of the late presenting Tendo Achilles rupture. A proximal intra muscular Z lengthening through a separate incision facilitates distal translation of the proximal tendon stump, allowing direct repair distally with minimum tension. Post operatively, a below knee cast is applied for six weeks, with progressive dorsiflexion at two weekly intervals. A dorsiflexion restriction splint accompanies early physiotherapy for a further six weeks, with unprotected weight bearing commencing at three months. There were eleven patients in the study group with an average follow up of 24 months. All tendons united. There were no re-ruptures. Two distal wound breakdowns occurred and one of these healed by secondary intention. Good single stance power returned in patients with smaller separations but greater calf wasting and weakness was observed in those patients with large separations. We conclude that this technique can be employed for the reconstruction of late presenting Achilles tendon ruptures, but great care is required with soft tissue dissection distally.
The operative and non-operative treatment options for acute tendo achilles rupture are well documented in the literature. The management of late presenting tendon rupture is usually operative, and can be complicated by acute shortening of the muscle-tendon unit and leave repairs under tension, which may lead to re-rupture. We report the use of the sliding graft technique for reconstruction of late presenting rupture. A proximal intra muscular Z lengthening through a separate incision facilitates distal translation of the proximal tendon stump, allowing direct repair distally with minimum tension. Post operatively a below knee cast is applied for six weeks with progressive dorsiflexion at two weekly intervals. A dorsiflexion restriction splint accompanies early physiotherapy for a further six weeks with unprotected weight bearing commencing at three months. There were eleven patients in the study group with an average follow up of 13 months. All tendons united. There were no re-ruptures. Two distal wound breakdowns occurred and one of these healed by secondary intention. Good single stance power returned in patients with smaller separations but greater calf wasting and weakness was observed in those patients with large separations. We conclude that this technique can be employed for the reconstruction of late presenting tendo achilles ruptures but great care is required with soft tissue dissection distally. Consideration could be given to deep flexor transfers in the widely separated case.
