A comparison was made of the results produced by the circumtibial and interosseous routes of transfer of tibialis posterior for the
Spasm or contracture of gastrocnemius causes an equinus deformity of the ankle in both cerebral palsy and hemiplegia. Its release is therefore required in the treatment of those patients who do not respond to conservative measures. The Vulpius procedure is a simple and effective method for the release of gastrocnemius and is particularly indicated when long periods of immobilisation of the foot and ankle are not desirable. We have used this procedure with good results to correct an equinus deformity in 230 adults with a cerebrovascular accident and various associated medical conditions. It is not only effective in cerebral palsy, but should be considered at an early stage in all adult patients with deformity of the ankle and foot in whom spasm of gastrocnemius is the major cause.
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 age (± seven years); 4) aetiology of the shortening, and 5) level of difficulty in obtaining the
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.

Subtalar distraction bone-block arthrodesis for malunited calcaneal fractures was performed in 31 patients (26 men, five women), with a mean age of 38.5 years. The mean time from injury to arthrodesis was 36 months. There were no cases of nonunion. One patient had an early dislocation of the bone block requiring a repeat arthrodesis, and one had a soft-tissue infection. The mean AOFAS hindfoot score improved significantly from 23.5 before operation to 73.2 at a mean follow-up of 33 months (p >
0.001). Compared with the unaffected side, the talocalcaneal height was corrected by 61.8%, the talus-first metatarsal axis by 46.5%, the talar declination angle by 38.5% and the talocalcaneal angle by 35.4%. Dynamic pedobarography revealed a return to normal of the pressure distribution during roll-over and a more energetic gait. The distribution of local transfer of load correlated well with the AOFAS score. The amount of
Injury to the dorsomedial cutaneous nerve in the foot may occur after operations for hallux valgus. Pressure neuropathy before operation is also described but remains largely unexplored. We have investigated the incidence of sensory deficit in the great toe before operating for hallux valgus and examined to what extent any deficit was related to the degree of angulation of the joint. Forty-three patients with a total of 61 great toes with hallux valgus presenting for consideration of surgical
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
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:
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 age differences
between groups, reduced the risk of deep vein thrombosis at the
two-week point (OR = 2.60; 95% CI 1.15 to 5.91; p =0.022). At six weeks,
the incidence of deep vein thrombosis was 52% in the treated group
and 48% in the control group (OR 0.94, 95% CI 0.49 to 1.83). IPC
appears to be an effective method of reducing the risk of deep vein
thrombosis in the early stages of post-operative immobilisation
of outpatients. Further research is necessary to elucidate whether
it can confer similar benefits over longer periods of immobilisation
and in a more heterogeneous group of patients. 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:
In this retrospective study we have assessed the results of low tibial valgus osteotomy for varus-type osteoarthritis of the ankle and its indications. We performed an opening wedge osteotomy in 25 women (26 ankles). The mean follow-up was for eight years and three months (2 years 3 months to 17 years 11 months). Of the 26 ankles, 19 showed excellent or good clinical results. Their mean scores for pain, walking, and activities of daily living were significantly improved but there was no change in the range of movement. In the ankles which were classified radiologically as stage 2 according to our own grading system, with narrowing of the medial joint space, and in 11 as stage 3a, with obliteration of the joint space at the medial malleolus only, the joint space recovered. In contrast, such recovery was seen in only two of 12 ankles classified as stage 3b, with obliteration of the joint space advancing to the upper surface of the dome of the talus. Low tibial osteotomy is indicated for varus-type osteoarthritis of stage 2 or stage 3a.
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%).
We prospectively evaluated the one- and seven-year results of the Weil osteotomy for the treatment of metatarsalgia with subluxed or dislocated metatarsophalangeal joints in 25 feet of 24 patients. Good to excellent results were achieved in 21 feet (84%) after one year and in 22 (88%) after seven years. The American Orthopaedic Foot and Ankle Society score significantly improved from 48 (
