Aims. This study describes the Osseointegration Group of Australia’s
Accelerated Protocol two-stage strategy (OGAAP-1) for the osseointegrated
reconstruction of amputated limbs. Patients and Methods. We report clinical outcomes in 50 unilateral trans-femoral amputees

Although patients with a history of venous thromboembolism
(VTE) who undergo lower limb joint replacement are thought to be
at high risk of further VTE, the actual rate of recurrence has not
been reported. The purpose of this study was to identify the recurrence rate
of VTE in patients who had undergone lower limb joint replacement,
and to compare it with that of patients who had undergone a joint
replacement without a history of VTE. . From a pool of 6646 arthroplasty procedures (3344 TKR, 2907 THR,
243 revision THR, 152 revision TKR) in 5967 patients (68% female,

Objectives. Induced membrane technique is a relatively new technique in the reconstruction of large bone defects. It involves the implantation of polymethylmethacrylate (PMMA) cement in the bone defects to induce the formation of membranes after radical debridement and reconstruction of bone defects using an autologous cancellous bone graft in a span of four to eight weeks. The purpose of this study was to explore the clinical outcomes of the induced membrane technique for the treatment of post-traumatic osteomyelitis in 32 patients. Methods. A total of 32 cases of post-traumatic osteomyelitis were admitted to our department between August 2011 and October 2012. This retrospective study included 22 men and ten women, with a mean
Deep vein thrombosis is a common complication
of immobilising the lower limb after surgery. We hypothesised that
intermittent pneumatic compression (IPC) therapy in outpatients
who had undergone surgical repair of acute ruptures of the Achilles
tendon could reduce the incidence of this problem. A total of 150 patients who had undergone surgical repair of
the Achilles tendon were randomised to either treatment with IPC
for six hours per day (n = 74) under an orthosis or treatment as
usual (n = 74) in a plaster cast without IPC. At two weeks post-operatively,
the incidence of deep vein thrombosis was assessed using blinded, double-reported
compression duplex ultrasound. At this point, IPC was discontinued
and all patients were immobilised in an orthosis for a further four
weeks. At six weeks post-operatively, a second compression duplex ultrasound
scan was performed. At two weeks, the incidence of deep vein thrombosis was 21% in
the treated group and 37% in the control group (p = 0.042). Age
over 39 years was found to be a strong risk factor for deep vein
thrombosis (odds ratio (OR) = 4.84, 95% confidence interval (CI)
2.14 to 10.96). Treatment with IPC, corrected for
Intramedullary infection in long bones represents
a complex clinical challenge, with an increasing incidence due to the
increasing use of intramedullary fixation. We report a prospective
case series using an intramedullary reaming device, the Reamer–Irrigator–Aspirator
(RIA) system, in association with antibiotic cement rods for the
treatment of lower limb long bone infections. A total of 24 such
patients, 16 men and eight women, with a mean
We compared lower limb coronal alignment measurements
obtained pre- and post-operatively with long-leg radiographs and
computer navigation in patients undergoing primary total knee replacement
(TKR). A series of 185 patients had their pre- and post-implant
radiological and computer-navigation system measurements of coronal alignment
compared using the Bland-Altman method. The study included 81 men
and 104 women with a mean
We compared the complications and outcome of tibial lengthening using the Ilizarov method with and without the use of a supplementary intramedullary nail. In a retrospective case-matched series assembled from 176 patients with tibial lengthening, we matched 52 patients (26 pairs, group A with nail and group B without) according to the following criteria in order of importance: 1) difference in amount of lengthening (± 2 cm); 2) percentage difference in lengthening (± 5%); 3) difference in patient’s
We have studied 105 patients with 107 acute, primary, dislocations of the glenohumeral joint seen between January 1, 1991 and July 1, 1994. The mean time of follow-up was 71 months (46 to 91). In 34% the injury occurred during a sports activity and in 28% at home. The bias toward sport was even greater in patients less than 40 years of
Internal lengthening devices in the femur lengthen
along the anatomical axis, potentially creating lateral shift of
the mechanical axis. We aimed to determine whether femoral lengthening
along the anatomical axis has an inadvertent effect on lower limb
alignment. Isolated femoral lengthening using the Intramedullary
Skeletal Kinetic Distractor was performed in 27 femora in 24 patients
(mean
We investigated the fracture-free survival of long bones stabilised by a telescopic intramedullary rod (TIMR) in patients with osteogenesis imperfecta with respect to the remodelling status of fracture or osteotomy sites and TIMR regions, in order to identify risk factors for fracture. A total of 44 femora and 28 tibiae in 25 patients with a mean
We present the results of the surgical correction of lower-limb deformities caused by metabolic bone disease. Our series consisted of 17 patients with a diagnosis of hypophosphataemic rickets and two with renal osteodystrophy; their mean
Vascular malformations are rare congenital lesions which often have associated skeletal changes. Over a period of ten years, 90 patients at our clinic had a vascular anomaly of the lower limb, examined by either CT or MRI. Of these, 18 (20%) had bony involvement. A questionnaire was sent to these patients (8 men, 10 women) to evaluate their
Fragility fractures of the ankle occur mainly in elderly osteoporotic women. They are inherently unstable and difficult to manage. There is a high incidence of complications with both non-operative and operative treatment. We treated 12 such fractures by closed reduction and stabilisation using a retrograde calcaneotalotibial expandable nail. The mean
It has been suggested that arthrodesis of the ankle leads to osteoarthritis of the joints of the ipsilateral hind- and midfoot. We believe these studies overlooked the presence of osteoarthritic changes in these joints before the arthrodesis. We reviewed the pre-operative radiographs of 70 patients with osteoarthritis of the ankle who underwent 71 ankle arthrodeses (one was bilateral). The talonavicular, calcaneocuboid, subtalar and naviculocuneiform joints were given an osteoarthritis score according to Kellgren and Lawrence. The mean
Diabetes mellitus is considered an indicator of poor prognosis for acute ankle fractures, but this risk may be specific to an identifiable subpopulation. We retrospectively reviewed 42 patients with both diabetes mellitus and an acute, closed, rotational ankle fracture. Patients were individually matched to controls by
The results of primary total knee replacement performed on a group of haemophiliac patients in a single institution by the same surgeon using the same surgical technique and prosthesis are reported. A total of 35 primary replacements in 30 patients were carried out between 1996 and 2005 and were reviewed retrospectively. The mean
Our aim was to evaluate the results of triple arthrodesis, performed without the use of supplementary bone graft. We carried out a retrospective review of 100 consecutive triple arthrodeses. All the operations had been performed by the senior author (TSS) using a standard technique. Only local bone graft from the excised joint surfaces had been used, thereby avoiding complications at the donor site. The mean
We reviewed 116 patients who underwent 118 arthroscopic ankle arthrodeses. The mean
Patients with diabetes mellitus may develop plantar flexion contractures (equinus) which may increase forefoot pressure during walking. In order to determine the relationship between equinus and forefoot pressure, we measured forefoot pressure during walking in 27 adult diabetics with a mean
Patients undergoing femoral lengthening by external fixation
tolerate treatment less well when compared to tibial lengthening.
Lengthening of the femur with an intramedullary device may have
advantages. We reviewed all cases of simple femoral lengthening performed
at our unit from 2009 to 2014. Cases of nonunions, concurrent deformities,
congenital limb deficiencies and lengthening with an unstable hip
were excluded, leaving 33 cases (in 22 patients; 11 patients had
bilateral procedures) for review. Healing index, implant tolerance
and complications were compared.Aims
Patients and Methods
The results of treatment of Lisfranc injuries are often unsatisfactory. This retrospective study investigated 46 patients with isolated Lisfranc injuries at a minimum of two years after surgery. Thirteen patients had a poor outcome and had to change employment, or were unable to find work as a result of this injury. The presence of a compensation claim (p = 0.02) and a delay in diagnosis of more than six months were associated with a poor outcome (p = 0.01). There was no association between poor functional outcome and

We treated 52 patients with impingement of the anterolateral soft tissues of the ankle by arthroscopic debridement. All had a history of single or multiple inversion injuries, without instability. One half had negative stress radiographs (stable group), while the others were positive (unstable group). Their mean
Of 111 primary ankle ligament arthroplasties (modified Evans procedure) performed between 1983 and 1994, we were able to identify 89 patients (94 ankles) for follow-up. All were under 50 years of
The Chevron osteotomy was described in 1976. There have, however, been only short- to mid-term follow-up reviews, often with small numbers of patients. We looked at 112 feet (73 patients) with a minimum follow-up of ten years following Chevron osteotomy with a distal soft-tissue procedure. Clinical evaluation was calculated using the hallux score of the American Orthopedic Foot and Ankle Society (AOFAS). For 47 feet (30 patients), the results were compared with those from an interim follow-up of 5.6 years. The AOFAS-score improved from a pre-operative mean of 46.5 points to a mean of 88.8 points after a mean of 12.7 years. The first metatarsophalangeal (MTP) angle showed a mean pre-operative value of 27.6° and was improved to 14.0°. The first intermetatarsal (IM) angle improved from a pre-operative mean value of 13.8° to 8.7°. The mean pre-operative grade of sesamoid subluxation was 1.7 on a scale from 0 to 3 and improved to 1.2. Measured on a scale from 0 to 3, arthritis of the first MTP joint progressed from a mean of 0.8 to 1.7. Comparing the results in patients younger and older than 50 years, the Chevron osteotomy performed equally in both
This retrospective study analyses the results of subtalar bone block distraction arthrodesis used in the treatment of late complications of calcaneal fractures, acute severely comminuted fractures, nonunion (and malunion) of attempted subtalar arthrodeses, avascular necrosis of the talus, and club-foot deformity. Of 39 patients (41 feet) who had this procedure, 35 (37 feet) returned for follow-up after a mean of 70 months (26 to 140). There were 24 men (25 feet) and 11 women (12 feet) with a mean
Infected nonunion of a long bone continues to
present difficulties in management. In addition to treating the infection,
it is necessary to establish bony stability, encourage fracture
union and reconstruct the soft-tissue envelope. We present a series of 67 infected nonunions of a long bone in
66 patients treated in a multidisciplinary unit. The operative treatment
of patients suitable for limb salvage was performed as a single
procedure. Antibiotic regimes were determined by the results of
microbiological culture. At a mean follow-up of 52 months (22 to 97), 59 patients (88%)
had an infection-free united fracture in a functioning limb. Seven
others required amputation (three as primary treatment, three after
late failure of limb salvage and one for recalcitrant pain after
union). The initial operation achieved union in 54 (84%) of the salvaged
limbs at a mean of nine months (three to 26), with recurrence of
infection in 9%. Further surgery in those limbs that remained ununited
increased the union rate to 62 (97%) of the 64 limbs treated by
limb salvage at final follow-up. The use of internal fixation was
associated with a higher risk of recurrent infection than external
fixation. Cite this article:
The treatment of infected nonunions is difficult.
Antibiotic cement-coated (ACC) rods provide stability as well as delivering
antibiotics. We conducted a review of 110 infected nonunions treated
with ACC rods. Patients were divided into two groups: group A (67
patients) with an infected arthrodesis, and group B (43 patients)
with an infected nonunion in a long bone. In group A, infected arthrodesis,
the success rate after the first procedure was 38/67 (57%), 29/67
(43%) required further surgery for either control of infection or
non-union. At last follow-up, five patients required amputation,
representing a limb salvage rate of 62/67 (93%) overall. In all,
29/67 (43%) presented with a bone defect with a mean size of 6.78
cm (2 to 25). Of those with a bone defect, 13/29 (45%) required
further surgery and had a mean size of defect of 7.2 cm (3.5 to
25). The cultures were negative in 17/67 (26%) and the most common
organism cultured was methicillin-resistant Cite this article:
Although gradual bone transport may permit the
restoration of large-diameter bones, complications are common owing
to the long duration of external fixation. In order to reduce such
complications, a new technique of bone transport involving the use
of an external fixator and a locking plate was devised for segmental
tibial bone defects. A total of ten patients (nine men, one woman) with a mean age
at operation of 40.4 years (16 to 64) underwent distraction osteogenesis
with a locking plate to treat previously infected post-traumatic
segmental tibial defects. The locking plate was fixed percutaneously
to bridge proximal and distal segments, and was followed by external fixation.
After docking, percutaneous screws were fixed at the transported
segment through plate holes. At the same time, bone grafting was
performed at the docking site with the external fixator removed. The mean defect size was 5.9 cm (3.8 to 9.3) and mean external
fixation index was
13.4 days/cm (11.8 to 19.5). In all cases, primary union of the
docking site and distraction callus was achieved, with an excellent
bony result. There was no recurrence of deep infection or osteomyelitis,
and with the exception of one patient with a pre-existing peroneal
nerve injury, all achieved an excellent or good functional result. With short external fixation times and low complication rates,
bone transport with a locking plate could be recommended for patients
with segmental tibial defects. Cite this article:
We hypothesised that adjuvant intermittent pneumatic
compression (IPC) beneath a plaster cast would reduce the risk of
deep-vein thrombosis (DVT) during post-operative immobilisation
of the lower limb. Of 87 patients with acute tendo Achillis (TA)
rupture, 26 were prospectively randomised post-operatively after
open TA repair. The treatment group (n = 14) received two weeks of
IPC of the foot for at least six hours daily under a plaster cast.
The control group (n = 12) had no additional treatment. At two weeks
post-operatively all patients received an orthosis until follow-up
at six weeks. At two and six weeks the incidence of DVT was assessed
using colour duplex sonography by two ultrasonographers blinded
to the treatment. Two patients withdrew from the study due to inability
to tolerate IPC treatment. An interim analysis demonstrated a high incidence of DVT in both
the IPC group (9 of 12, 75%) and the controls (6 of 12, 50%) (p
= 0.18). No significant differences in incidence were detected at
two (p = 0.33) or six weeks (p = 0.08) post-operatively. Malfunction
of the IPC leading to a second plaster cast was found to correlate
with an increased DVT risk at two weeks (φ = 0.71; p = 0.019), leading
to a premature abandonment of the study. We cannot recommend adjuvant treatment with foot IPC under a
plaster cast for outpatient DVT prevention during post-operative
immobilisation, owing to a high incidence of DVT related to malfunctioning
of this type of IPC application. Cite this article:

of 49 years (35 to 66). All outcome measures were recorded at baseline,

Methods
We carried out a systematic review of the literature
to evaluate the evidence regarding the clinical results of the Ilizarov
method in the treatment of long bone defects of the lower limbs. Only 37 reports (three non-randomised comparative studies, one
prospective study and 33 case-series) met our inclusion criteria.
Although several studies were unsatisfactory in terms of statistical
heterogeneity, our analysis appears to show that the Ilizarov method
of distraction osteogenesis significantly reduced the risk of deep
infection in infected osseous lesions (risk ratio 0.14 (95% confidence
interval (CI) 0.10 to 0.20), p <
0.001). However, there was a
rate of re-fracture of 5% (95% CI 3 to 7), with a rate of neurovascular
complications of 2.2% (95% CI 0.3 to 4) and an amputation rate of
2.9% (95% CI 1.4 to 4.4).The data was generally not statistically
heterogeneous. Where tibial defects were >
8 cm, the risk of re-fracture
increased (odds ratio 3.7 (95% CI 1.1 to 12.5), p = 0.036). The technique is demanding for patients, illustrated by the voluntary
amputation rate of 1.6% (95% CI 0 to 3.1), which underlines the
need for careful patient selection. Cite this article:
Incomplete avulsion of the proximal hamstrings
can be a severely debilitating injury that causes weakness, pain
while sitting and inability to run. The results of the surgical treatment
of 23 consecutive patients with such injuries at least two years
after surgery are described. The surgery consisted of the repair
of the hamstrings directly onto the ischial tuberosity. At review,
using a visual analogue scale (VAS, 0 to 100), pain while sitting improved
from a mean of 40 (0 to 100) to 64 (0 to 100) (p = 0.024), weakness
from a mean of 39 (0 to 90) to 76 (7 to 100) (p = 0.0001) and the
ability to run from a mean of 24 (0 to 88) to 64 (0 to 95) (p =
0.0001). According to a VAS, satisfaction was rated at a mean of
81 (0 to 100) and 20 patients (87%) would have the same procedure
again. Hamstring strength measured pre- and post-operatively had
improved significantly from a mean of 64% (0% to 95%) to 88% (50%
to 114%) compared with the normal side. Most of these patients with symptomatic incomplete hamstring
avulsions unresponsive to conservative treatment had an improved
outcome after surgical repair.

strength (p = 0.0001) and gap resistance (p = 0.01) of bovine tendon

The use of autograft bone is the best option
when undertaking a procedure that requires bone graft because it
is osteogenic, osteoconductive and osseo-inductive. Pain, morbidity
and complications associated with harvesting iliac or non-iliac
sites occur in between 6% and 30% of cases. An alternative source
of graft with possibly a lower morbidity is the intramedullary canal.
In this study, 28 patients undergoing 30 arthrodesis procedures
on the hindfoot had a mean of 48 cm3 (43 to 50) of bone
harvested locally from the hindfoot or the tibial shaft by antegrade or
retrograde reaming. No patient sustained a fracture of the calcaneum,
talus or tibia. There was no morbidity except for one complication
when the reamer breached the medial tibial cortex. This healed uneventfully. This method of using the reamer–irrigator–aspirator system is
an extension of the standard technique of intramedullary reaming
of the lower limb: it produces good-quality bone graft with viable
growth factors consistent with that of the iliac crest, and donor
site morbidity is low. This is an efficient method of obtaining
autologous bone for use in arthrodesis of the ankle or hindfoot.
Between October 2001 and September 2009 we lengthened 242 lower-limb segments in 180 patients using the Intramedullary Skeletal Kinetic Distractor (ISKD). Mechanical failure was defined either as breakage of the ISKD or failure of the internal mechanism to activate. Retrieved nails which failed mechanically were examined by the manufacturer for defects. In all, 15 ISKDs in 12 patients (13 limbs) failed mechanically representing an overall failure rate of 6.2%, with fracture of the device occurring in ten of the 15 failures. Two nails in one patient failed to lengthen and had to be replaced. The manufacturer detected an error in the assembly of the nail, which prompted a wide recall. One nail jammed after being forcefully inserted, and two nails failed to lengthen fully. Lengthening was achieved in all 12 patients, although three required a second operation to exchange a defective nail for a new, functioning device. The ISKD is a complex mechanical device which lengthens by the oscillation of two telescopic sections connected by a threaded rod. The junction between these sections is surrounded by a keyring collar. This keyring collar is the weakest part of the device.
We report the results of intramedullary leg lengthening conducted between 2002 and 2009 using the Intramedullary Skeletal Kinetic Distractor in 69 unilateral lengthenings involving 58 femora and 11 tibiae. We identified difficulties that occurred during the treatment and assessed whether they were specifically due to the implant or independent of it. Paley’s classification for evaluating problems, obstacles and complications with external fixators was adopted, and implant-specific difficulties were continuously noted. There were seven failures requiring premature removal of the device, in four due to nail breakage and three for other reasons, and five unsuccessful outcomes after completion of the lengthening. In all, 116 difficulties were noted in 45 patients, with only 24 having problem-free courses. In addition to the difficulties arising from the use of external fixators, there were almost the same number again of implant-specific difficulties. Nevertheless, successful femoral lengthening was achieved in 52 of the 58 patients (90%). However, successful tibial lengthening was only achieved in five of 11 patients (45%).
The purpose of this study was to investigate the effects of right leg restriction at the knee, ankle or both, on a driver’s braking times. Previous studies have not investigated the effects of knee restriction on braking performance. A total of 23 healthy drivers performed a series of emergency braking tests in a driving simulator in either an above-knee plaster cast, a below-knee cast, or in a knee brace with an increasing range of restriction. The study showed that total braking reaction time was significantly longer when wearing an above-knee plaster cast, a below-knee plaster cast or a knee brace fixed at 0°, compared with braking normally (p <
0.001). Increases in the time taken to move the foot from the accelerator to the brake accounted for some of the increase in the total braking reaction time. Unexpectedly, thinking time also increased with the level of restriction (p <
0.001). The increase in braking time with an above-knee plaster cast in this study would increase the stopping distance at 30 miles per hour by almost 3 m. These results suggest that all patients wearing any lower-limb plaster cast or knee brace are significantly impaired in their ability to perform an emergency stop. We suggest changes to the legislation to prevent patients from driving with lower-limb plaster casts or knee braces.
The intra-articular injection of local anaesthetic is frequently used for pain relief after arthroscopy. There is, however, no published evidence of the analgesic effect of bupivacaine in the ankle. In a randomised, double-blind study, 35 patients undergoing arthroscopy of the ankle were allocated to receive intra-articular saline or bupivacaine. Pain was assessed using pain scores and additional analgesic requirements. Intra-articular bupivacaine had a significant analgesic effect in the immediate post-operative period, reducing pain scores and the need for additional analgesics. We recommend the use of intra-articular bupivacaine for post-operative analgesia in ankle surgery.
Between 1999 and 2005, 23 failed total ankle replacements were converted to arthrodeses. Three surgical techniques were used: tibiotalar arthrodesis with screw fixation, tibiotalocalcaneal arthrodesis with screw fixation, and tibiotalocalcaneal arthrodesis with an intramedullary nail. As experience was gained, the benefits and problems became apparent. Successful bony union was seen in 17 of the 23 ankles. The complication rate was higher in ankles where the loosening had caused extensive destruction of the body of the talus, usually in rheumatoid arthritis. In this situation we recommend tibiotalocalcaneal arthrodesis with an intramedullary nail. This technique can also be used when there is severe arthritic change in the subtalar joint. Arthrodesis of the tibiotalar joint alone using compression screws was generally possible in osteoarthritis because the destruction of the body of the talus was less extensive. Tibiotalocalcaneal arthrodesis fusion with compression screws has not been successful in our experience.
Advances in the design of the components for total ankle replacement have led to a resurgence of interest in this procedure. Between January 1999 and December 2004, 16 patients with a failed total ankle replacement were referred to our unit. In the presence of infection, a two-stage salvage procedure was planned. The first involved the removal of the components and the insertion of a cement spacer. Definitive treatment options included hindfoot fusion with a circular frame or amputation. When there was no infection, a one-stage salvage procedure was planned. Options included hindfoot fusion with an intramedullary nail or revision total ankle replacement. When there was suspicion of infection, a percutaneous biopsy was performed. The patients were followed up for a minimum of 12 months. Of the 16 patients, 14 had aseptic loosening, five of whom underwent a revision total ankle replacement and nine a hindfoot fusion. Of the two with infection, one underwent fusion and the other a below-knee amputation. There were no cases of wound breakdown, nonunion or malunion. Management of the failed total ankle replacement should be performed by experienced surgeons and ideally in units where multidisciplinary support is available. Currently, a hindfoot fusion appears to be preferable to a revision total ankle replacement.
In a prospective randomised study 31 patients were allocated to either arthrodesis or Mayo resection of the first metatarsophalangeal joint as part of a total reconstruction of the rheumatoid forefoot. Of these, 29 were re-examined after a mean of 72 months (57 to 80), the Foot Function Index was scored and any deformity measured. Load distribution was analysed using a Fscan mat in 14 cases, and time and distance were measured in 12 of these patients using a 3D Motion system. We found excellent patient satisfaction and a significant, lasting reduction of the Foot Function Index, with no statistically significant differences between the groups. There were no significant differences in recurrence of the deformity, the need for special shoes, gait velocity, step length, plantar moment, mean pressure or the position of the centre of force under the forefoot. The cadence was higher and the stance phase shorter in the fusion group. These results suggest that a Mayo resection may be an equally good option for managing the first metatarsophalangeal joint in reconstruction of the rheumatoid forefoot.
We performed two independent, randomised, controlled trials in order to assess the potential benefits of immediate weight-bearing mobilisation after rupture of the tendo Achillis. The first trial, on operatively-treated patients showed an improved functional outcome for patients mobilised fully weight-bearing after surgical repair. Two cases of re-rupture in the treatment group suggested that careful patient selection is required as patients need to follow a structured rehabilitation regimen. The second trial, on conservatively-treated patients, provided no evidence of a functional benefit from immediate weight-bearing mobilisation. However, the practical advantages of immediate weight-bearing did not predispose the patients to a higher complication rate. In particular, there was no evidence of tendon lengthening or a higher re-rupture rate. We would advocate immediate weight-bearing mobilisation for the rehabilitation of all patients with rupture of the tendo Achillis.
We describe the results of arthrodesis for the treatment of recurrent acute neuropathic bone disease in 24 feet and of chronic disease with deformity in 91 feet, undertaken between January 1984 and December 2003. All were due to leprosy. Correction of the deformity was achieved in 80 of 106 feet (76%) and fusion in 97 of 110 feet (88%). In the 24 feet in which recurrent neuropathic bone disease was the reason for surgery, 17 (71%) obtained stability while in seven (29%) symptoms recurred postoperatively. Complications were experienced following 58 of the 110 operations (53%). In patients presenting primarily with deformity with a minimum follow-up of two years (79 feet), there was a reduced frequency of ulceration in 40 (51%). Normal footwear could be worn by 32 patients (40%) after surgery, while 40 (51%) required a moulded insole. Arthrodesis of the ankle in the neuropathic foot due to leprosy has a good overall rate of success although the rate of complications is high.
