The aim of this study was to report the results of three forms of reconstruction for patients with a ditsl tibial bone tumour: an intercalary resection and reconstruction, an osteoarticular reconstruction, and arthrodesis of the ankle. A total of 73 patients with a median age of 19 years (interquartile range (IQR) 14 to 36) were included in this retrospective, multicentre study.Aims
Methods
The Fassier Duval (FD) rod is a third-generation telescopic implant for children with osteogenesis imperfecta (OI). Threaded fixation enables proximal insertion without opening the knee or ankle joint. We have reviewed our combined two-centre experience with this implant. In total, 34 children with a mean age of five years (1 to 14) with severe OI have undergone rodding of 72 lower limb long bones (27 tibial, 45 femoral) for recurrent fractures with progressive deformity despite optimized bone health and bisphosphonate therapy. Data were collected prospectively, with 1.5 to 11 years follow-up.Aims
Methods
Carpal malalignment after a distal radial fracture occurs due to loss of volar tilt. Several studies have shown that this has an adverse influence on function. We aimed to investigate the magnitude of dorsal tilt that leads to carpal malalignment, whether reduction of dorsal tilt will correct carpal malalignment, and which measure of carpal malalignment is the most useful. Radiographs of patients with a distal radial fracture were prospectively collected and reviewed. Measurements of carpal malalignment were recorded on the initial radiograph, the radiograph following reduction of the fracture, and after a further interval. Linear regression modelling was used to assess the relationship between dorsal tilt and carpal malalignment. Receiver operating characteristic (ROC) analysis was used to identify which values of dorsal tilt led to carpal malalignment.Aims
Methods
There is little information about how to manage patients with a recurvatum deformity of the distal tibia and osteoarthritis (OA) of the ankle. The aim of this study was to evaluate the functional and radiological outcome of addressing this deformity using a flexion osteotomy and to assess the progression of OA after this procedure. A total of 39 patients (12 women, 27 men; mean age 47 years (28 to 72)) with a distal tibial recurvatum deformity were treated with a flexion osteotomy, between 2010 and 2015. Nine patients (23%) subsequently required conversion to either a total ankle arthroplasty (seven) or an arthrodesis (two) after a mean of 21 months (9 to 36). A total of 30 patients (77%), with a mean follow-up of 30 months (24 to 76), remained for further evaluation. Functional outcome, sagittal ankle joint OA using a modified Kellgren and Lawrence Score, tibial lateral surface (TLS) angle, and talar offset ratio (TOR) were evaluated on pre- and postoperative weight-bearing radiographs.Aims
Patients and Methods
Double-level lengthening, bone transport, and bifocal compression-distraction are commonly undertaken using Ilizarov or other fixators. We performed double-level fixator-assisted nailing, mainly for the correction of deformity and lengthening in the same segment, using a straight intramedullary nail to reduce the time in a fixator. A total of 23 patients underwent this surgery, involving 27 segments (23 femora and four tibiae), over a period of ten years. The most common indication was polio in ten segments and rickets in eight; 20 nails were inserted retrograde and seven antegrade. A total of 15 lengthenings were performed in 11 femora and four tibiae, and 12 double-level corrections of deformity without lengthening were performed in the femur. The mean follow-up was 4.9 years (1.1 to 11.4). Four patients with polio had tibial lengthening with arthrodesis of the ankle. We compared the length of time in a fixator and the external fixation index (EFI) with a control group of 27 patients (27 segments) who had double-level procedures with external fixation. The groups were matched for the gain in length, age, and level of difficulty score.Aims

alternative to staged re-implantation. Between 1990 and 2010, 23 consecutive patients were treated in
this way. Three were lost to follow-up leaving 20 patients (21 TEAs)
in the study. There were six men and 14 women. Their mean age was
58 years (23 to 76). The protocol involved: component unlinking,
irrigation and debridement (I&

Patients and Methods
The aim of this study was to report a single surgeon series of
consecutive patients with moderate hallux valgus managed with a
percutaneous extra-articular reverse-L chevron (PERC) osteotomy. A total of 38 patients underwent 45 procedures. There were 35
women and three men. The mean age of the patients was 48 years (17
to 69). An additional percutaneous Akin osteotomy was performed
in 37 feet and percutaneous lateral capsular release was performed
in 22 feet. Clinical and radiological assessments included the type
of forefoot, range of movement, the American Orthopedic Foot and
Ankle (AOFAS) score, a subjective rating and radiological parameters. The mean follow-up was 59.1 months (45.9 to 75.2). No patients
were lost to follow-up.Aims
Patients and Methods
The traditional techniques involving an oblique
tunnel or triangular wedge resection to approach a central or mixed-type
physeal bar are hindered by poor visualisation of the bar. This
may be overcome by a complete transverse osteotomy at the metaphysis
near the growth plate or a direct vertical approach to the bar.
Ilizarov external fixation using small wires allows firm fixation
of the short physis-bearing fragment, and can also correct an associated angular
deformity and permit limb lengthening. We accurately approached and successfully excised ten central-
or mixed-type bars; six in the distal femur, two in the proximal
tibia and two in the distal tibia, without damaging the uninvolved
physis, and corrected the associated angular deformity and leg-length
discrepancy. Callus formation was slightly delayed because of periosteal
elevation and stretching during resection of the bar. The resultant
resection of the bar was satisfactory in seven patients and fair
in three as assessed using a by a modified Williamson–Staheli classification. Cite this article:
Moderate to severe hallux valgus is conventionally
treated by proximal metatarsal osteotomy. Several recent studies
have shown that the indications for distal metatarsal osteotomy
with a distal soft-tissue procedure could be extended to include
moderate to severe hallux valgus. The purpose of this prospective randomised controlled trial was
to compare the outcome of proximal and distal Chevron osteotomy
in patients undergoing simultaneous bilateral correction of moderate
to severe hallux valgus. The original study cohort consisted of 50 female patients (100
feet). Of these, four (8 feet) were excluded for lack of adequate
follow-up, leaving 46 female patients (92 feet) in the study. The
mean age of the patients was 53.8 years (30.1 to 62.1) and the mean
duration of follow-up 40.2 months (24.1 to 80.5). After randomisation,
patients underwent a proximal Chevron osteotomy on one foot and

Resection of a primary sarcoma of the diaphysis
of a long bone creates a large defect. The biological options for reconstruction
include the use of a vascularised and non-vascularised fibular autograft. The purpose of the present study was to compare these methods
of reconstruction. Between 1985 and 2007, 53 patients (26 male and 27 female) underwent
biological reconstruction of a diaphyseal defect after resection
of a primary sarcoma. Their mean age was 20.7 years (3.6 to 62.4).
Of these, 26 (49 %) had a vascularised and 27 (51 %) a non-vascularised
fibular autograft. Either method could have been used for any patient in
the study. The mean follow-up was 52 months (12 to 259). Oncological,
surgical and functional outcome were evaluated. Kaplan–Meier analysis
was performed for graft survival with major complication as the
end point. At final follow-up, eight patients had died of disease. Primary
union was achieved in 40 patients (75%); 22 (42%) with a vascularised
fibular autograft and 18 (34%) a non-vascularised (p = 0.167). A
total of 32 patients (60%) required revision surgery. Kaplan–Meier
analysis revealed a mean survival without complication of 36 months
(0.06 to 107.3, Both groups seem to be reliable biological methods of reconstructing
a diaphyseal bone defect. Vascularised autografts require more revisions
mainly due to problems with wound healing in distal sites of tumour,
such as the foot. Cite this article:
In this study we evaluated the results of midtarsal
release and open reduction for the treatment of children with convex
congenital foot (CCF) (vertical talus) and compared them with the
published results of peritalar release. Between 1977 and 2009, a
total of 22 children (31 feet) underwent this procedure. In 15 children
(48%) the CCF was isolated and in the remainder it was not (seven
with arthrogryposis, two with spinal dysraphism, one with a polymalformative
syndrome and six with an undefined neurological disorder). Pre-operatively, the mean tibiotalar angle was 150.2° (106° to
175°) and the mean calcaneal pitch angle was -19.3° (-72° to 4°).
The procedure included talonavicular and calcaneocuboid joint capsulotomies,
lengthening of tendons of tibialis anterior and the extensors of
the toes, allowing reduction of the midtarsal joints. Lengthening
of the Achilles tendon was necessary in 23 feet (74%). The mean follow-up was 11 years (2 to 21). The results, as assessed
by the Adelaar score, were good in 24 feet (77.4%), fair in six
(19.3%) and poor in one foot (3.3%), with no difference between
those with isolated CCF and those without. The mean American Orthopaedic
Foot and Ankle Society midfoot score was 89.9 (54 to 100) and 77.8
(36 to 93) for those with isolated CCF and those without, respectively.
At the final follow-up, the mean tibiotalar (120°; 90 to 152) and
calcaneal pitch angles (4°; -13 to 22) had improved significantly
(p <
0.0001). Dislocation of the talonavicular and calcaneocuboid
joints was completely reduced in 22 (70.9%) and 29 (93.6%) of feet,
respectively. Three children (five feet) underwent further surgery
at a mean of 8.5 years post-operatively, three with pes planovalgus
and two in whom the deformity had been undercorrected. No child
developed avascular necrosis of the talus. Midtarsal joint release and open reduction is a satisfactory
procedure, which may provide better results than peritalar release.
Complications include the development of pes planovalgus and persistent
dorsal subluxation of the talonavicular joint. Cite this article:
Using human cadaver specimens, we investigated
the role of supplementary fibular plating in the treatment of distal
tibial fractures using an intramedullary nail. Fibular plating is
thought to improve stability in these situations, but has been reported
to have increased soft-tissue complications and to impair union
of the fracture. We proposed that multidirectional locking screws
provide adequate stability, making additional fibular plating unnecessary.

As it remains unproven that hypermobility of
the first tarsometatarsal joint (TMTJ-1) is a significant factor
in hallux valgus deformity, the necessity for including arthrodesis
of TMTJ-1 as part of a surgical correction of a hallux valgus is
questionable. In order to evaluate the role of this arthrodesis
on the long-term outcome of hallux valgus surgery, a prospective,
blinded, randomised study with long-term follow-up was performed,
comparing the Lapidus procedure (which includes such an arthrodesis)
with a simple Hohmann distal closing wedge metatarsal osteotomy. The
study cohort comprised 101 feet in 87 patients: 50 feet were treated
with a Hohmann procedure and 51 with a Lapidus procedure. Hypermobility
of TMTJ-1 was assessed pre-operatively by clinical examination.
After a mean of 9.25 years (7.25 to 11.42), 91 feet in 77 patients
were available for follow-up. There was no difference in clinical
or radiological outcome between the two procedures. Also, there
was no difference in outcome between the two procedures in the subgroup
clinically assessed as hypermobile. This study does not support
the theory that a hallux valgus deformity in a patient with a clinically
assessed hypermobile TMTJ-1 joint requires fusion of the first tarso-metatarsal
joint. Cite this article:
In a retrospective study we compared 32 HINTEGRA
total ankle replacements (TARs) and 35 Mobility TARs performed between
July 2005 and May 2010, with a minimum follow-up of two years. The
mean follow-up for the HINTEGRA group was 53 months (24 to 76) and
for the Mobility group was 34 months (24 to 45). All procedures
were performed by a single surgeon. There was no significant difference between the two groups with
regard to the mean AOFAS score, visual analogue score for pain or
range of movement of the ankle at the latest follow-up. Most radiological
measurements did not differ significantly between the two groups.
However, the most common grade of heterotopic ossification (HO)
was grade 3 in the HINTEGRA group (10 of 13 TARs, 76.9%) and grade
2 in the Mobility group (four of seven TARs, 57.1%) (p = 0.025).
Although HO was more frequent in the HINTEGRA group (40.6%) than
in the Mobility group (20.0%), this was not statistically significant
(p = 0.065).The difference in peri-operative complications between
the two groups was not significant, but intra-operative medial malleolar
fractures occurred in four (11.4%) in the Mobility group; four (12.5%)
in the HINTEGRA group and one TAR (2.9%) in the Mobility group failed
(p = 0.185). Cite this article:

Severe hallux valgus deformity is conventionally
treated with proximal metatarsal
The purpose of this study was to assess the outcome
of 15 patients (mean age 13.6 years (7 to 25)) with a primary sarcoma
of the tibial diaphysis who had undergone excision of the affected
segment that was then irradiated (90 Gy) and reimplanted with an
ipsilateral vascularised fibular graft within it. The mean follow-up was 57 months (22 to 99). The mean time to
full weight-bearing was 23 weeks (9 to 57) and to complete radiological
union 42.1 weeks (33 to 55). Of the 15 patients, seven required
a further operation, four to obtain skin cover. The mean Musculoskeletal
Society Tumor Society functional score at final follow-up was 27
out of 30 once union was complete. The functional results were comparable
with those of allograft reconstruction and had a similar rate of
complication. We believe this to be a satisfactory method of biological reconstruction
of the tibial diaphysis in selected patients.
The treatment of substantial proximal femoral
bone loss in young patients with developmental dysplasia of the
hip (DDH) is challenging. We retrospectively analysed the outcome
of 28 patients (30 hips) with DDH who underwent revision total hip
replacement (THR) in the presence of a deficient proximal femur,
which was reconstructed with an allograft prosthetic composite.
The mean follow-up was 15 years (8.5 to 25.5). The mean number of
previous THRs was three (1 to 8). The mean age at primary THR and
at the index reconstruction was 41 years (18 to 61) and 58.1 years
(32 to 72), respectively. The indication for revision included mechanical
loosening in 24 hips, infection in three and peri-prosthetic fracture
in three. Six patients required removal and replacement of the allograft
prosthetic composite, five for mechanical loosening and one for
infection. The survivorship at ten, 15 and 20 years was 93% (95%
confidence interval (CI) 91 to 100), 75.5% (95% CI 60 to 95) and
75.5% (95% CI 60 to 95), respectively, with 25, eight, and four
patients at risk, respectively. Additionally, two junctional nonunions
between the allograft and host femur required bone grafting and
plating. An allograft prosthetic composite affords a good long-term outcome
in the management of proximal femoral bone loss in revision THR
in patients with DDH, while preserving distal host bone.
