Background:

Various surgical flaps have been described for the reconstruction of post traumatic soft tissue defects of the heel. These techniques are not all familiar to orthopaedic surgeons. The presented technique is based on the use of a reverse flow island sural flap combined with a circular external fixator.

Material:

This presentation is a review of 8 cases performed between 2003 and 2012.

We present a series of 88 non-unions in which non-union, infection, bony alignment and length were addressed simultaneously, by using the Sheffield Ring Fixator.

The mean follow up was 50 months (range 6–110) after union, which was achieved in 90.5% of the patients. The mean deformity correction was 16.80 (range 60–320), and mean length gain was 12.5 mm (range 2–40 mm).

Smoking and infection had a statistical significant association with the time of healing, as healing of the non-union in over 18 months was more common in smoker and patients with infected non-union.

There was no statistical difference between the functional score (SF-36) between these patients and normal population, at a follow up of minimum 2 years, but that was significant between pre operative and less than one year follow up on one side, and more than 2 years follow up on the other.

At Sheffield Children’s Hospital 40 children with leg length discrepancies (caused variously by sepsis, trauma, hemihypertrophy, congenital longitudinal deficiencies) were assessed using three clinical methods: measuring blocks in the standing erect position, supine measurement from the anterior superior iliac spine to the medial malleolus, and prone measurement with the knees flexed, which allowed separate measurement of femoral and tibial discrepancies. All were then subjected to comparative CT scanogram.

The mean age of the 24 boys and 16 girls was 10 years (5 to 16). Children with abnormal pelvic architecture or a fixed pelvic obliquity were excluded from the study. The mean clinical length discrepancy was 29 mm (0 to 80 mm). The mean CT scanogram measurement was 26.4 mm (0 to 75 mm). The mean difference between clinical measurements taken prone and CT scanogram measurements was only 3.6 mm (0 to 14). There was little difference in the accuracy of measuring femoral and tibial discrepancies clinically or by CT scanogram. The prone method of measurements is a useful adjunct to Staheli’s rotational profile in the prone position.

Nine children with knee and foot deformities were treated by Ilizarov external fixation from 1989 to 2000 at the Sheffield Children’s Hospital. Sixteen cases of arthrogryposis were identified. Progressive correction was combined with soft tissue release, soft tissue distraction or bony correction. Clinical outcomes were assessed and comparisons made between the different treatment modalities. Three fixed flexion deformities of the knee treated with progressive correction and soft tissue distraction were corrected initially, but recurred some time after the removal of fixators. Out of five clubfoot deformities treated with an Ilizarov frame with progressive soft tissue distraction alone, three recurred despite long-term splinting. Eight clubfoot deformities were treated with a bony procedure combined with gradual correction in the circular frame, and all corrections were maintained at follow-up.

The mean treatment time in the fixator was 17 weeks (12 to 50), and the mean follow-up time was 36 months. Complications included four cases of pin-tract sepsis, one case of osteitis requiring a sequestrectomy, one of transient neuropraxia and one fracture following removal of the fixator.

The treatment of joint deformities in arthrogryposis remains challenging and complications occur. Combining the Ilizarov device with a bony procedure seems to give better results, with fewer recurrence of deformities than pure progressive soft tissue correction.

Aim: To assess the outcome of operative treatment of joint deformities using circular external fixators in arthrogryposis

Materials and Methods: 16 cases were identified in 9 children, who underwent application of Ilizarov external fixation from 1989 to 2000 at the Sheffield Children’s Hospital for progressive correction of knee and foot deformities. This treatment modality was combined with either a soft tissue release, soft tissue distraction or a bony correction. Clinical outcomes were assessed, and comparisons were made between the different treatment modalities. Results: Three fixed flexion deformities of the knee treated with progressive correction and soft tissue distraction all achieved initial correction, but recurred some time after removal of fixators. Out of five club-feet treated with an Ilizarov frame with progressive soft tissue distraction alone, three deformities recurred despite long term splinting. The remaining eight club-foot deformities were treated with a bony procedure combined with gradual correction in the circular frame, and all corrections were maintained at follow up. The average treatment time in the fixator was 17 weeks (12–50 weeks), and the average follow up time was 36 months. Complications included 4 pin track sepses, 1 osteitis requiring a sequestrectomy, 1 transient neurapraxia and 1 fracture following removal of the fixator.

Conclusion: The treatment of joint deformities in arthrogryposis remains challenging and difficult, and complications do occur. Combining the Ilizarov device with a bony procedure seems to have superior results and less recurrence of deformities than pure progressive soft tissue correction.

After tuberculosis of the spine, hip and knee, tuberculosis of the foot and ankle is the most common occurring area of skeletal tuberculosis seen in our unit. We retrospectively reviewed 14 patients (14 feet and/or ankles) seen over the 16-year period 1982 to 1997.

The average age of the children was 5.2 years (range 1.5 to 11 years). The duration of symptoms ranged from 1 week to 1 year. The most common presentation was swelling and pain of the involved joint, but three patients each presented with a chronic discharging sinus after being drained elsewhere as an acute abscess. Radiographs revealed osteo-penia with or without lytic areas, joint margin destruction or joint space narrowing. The average sedimentation rate (ESR) was 52.3 mm/hour (range 9 to 120). The Mantoux test was positive in 13 out of the 14 patients. Chest x-rays demonstrated latent or active tuberculosis in 50% of patients. Open biopsy was performed in all patients. Hypertrophic synovium was found in all cases except one, where atrophic tuberculosis with joint space narrowing was present. A positive diagnosis of tuberculosis was made in all cases, either by demonstrating caseating granulomatous tissue on histology, or by growing a positive culture for mycobacterium tuberculosis or both. Histology was positive in 86%, acid-fast bacteria were seen in 28.5% and a positive culture was obtained in 82% of the patients.

At an average follow up of 7.4 years (range 1 to 17 years) all patients were assessed both clinically and radiologically. Patients with lytic lesions and destruction of joint margins reconstituted well radiologically, had a good clinical outcome with a good range of movement of the affected joint, however the one patient with atrophic tuberculosis remained with a narrowed joint space, stiffness and a poor clinical result compared to the rest.

The results of the first 100 consecutive patients treated in our tertiary referral non-union practice have been previously reported. The purpose of this report is to review this group together with a further 280 cases treated between 1991 and 2000. The principles of management remain the same, namely restoration of alignment, stabilisation and stimulation, however in the more recent cases increasing use of distraction, bone transport and bifocal techniques as well as single stage lengthening and correction of soft tissue contractures have been used to eliminate limb strength discrepancies. A total of 380 consecutive established non-unions treated between 1987 and 2000 were reviewed. Twenty-nine patients were lost to follow up (five deceased). There were 159 atrophic, 89 hypertrophic and 103 infected cases, with 319 cases as a result of trauma, and 32 cases as a consequence of planned surgery. The majority involved the tibia with 162 cases, followed by femoral non-unions with 51 cases and the remainder involving upper limb and smaller bones. At the time of review, 8 had abandoned treatment and 25 remained ununited. Twenty-one cases ended with amputations: 14 infected, 4 atrophic and 3 cases due to excessive pain following patients request.

Union was achieved in 297 cases (85% overall union rate), representing 90% of atrophic, 89% of hypertrophic and 73% of the infected non-unions. A comparison is made between the first hundred previously unreported series of 280 cases. The overall union rates have improved from 80% to 85%, with an increase in union rates noted predominantly in the atrophic group. Infected cases remain more of a problem and challenging with lower healing rates. There was no statistical difference in union rates between smokers and non-smokers, but slower times to union and increased complication rates were noted in the heavy smokers (< 40/day). The non-union profiles, pathogenesis and change in treatment options are discussed.

We reviewed 351 cases of nonunion treated between 1987 and 2000. The principles of management included restoration of alignment, stabilisation and stimulation. More recently we used distraction and bone transport, bifocal techniques, single stage lengthening and correction of soft tissue contractures.

The ununited fractures resulted from trauma in 319 cases and in 32 were the sequelae of planned surgery. There were 159 atrophic, 89 hypertrophic and 103 infected nonunions. Nonunion occurred in the tibia in 162 patients, in the femur in 51 and in the upper limbs and other smaller bones in the rest.

At the time of this review, nine patients had abandoned treatment and 25 fractures remained ununited. Amputation had been performed on 20 patients, two at the request of patients with intractable pain, 14 following infection and four because of atrophy. Union was achieved in 297 cases (85%), including 90% of the atrophic, 89% of the hypertrophic and 73% of the infected nonunions. We found no statistically significant difference between the results of patients who smoked and non-smokers, but patients who smoked heavily healed more slowly.

Hybrid fixation is now an established modality of treatment for articular fractures of the proximal and distal tibia. However, there is a lack of consensus over the management of non-articular metaphyseal fractures extending into the diaphysis. Despite sophisticated techniques, intramedullary nailing remains difficult and has relatively high rates of malunion and nonunion. Plate fixation may produce satisfactory results, but its use is limited where there is major extension into the diaphysis or where the soft tissues are compromised.

Since 1995, we have used hybrid external fixation in the treatment of such fractures in 24 male and 16 female patients of mean age 54 years (15 to 92). Mostly sustained in road traffic accidents, there were 26 closed and 14 open fractures, seven of which were Gustillo type IIIB. There were 26 distal tibial, seven proximal and seven tibial shaft fractures.

Metaphyseal fixation consisted of two rings with tension wires, diaphyseal fixation of screws. We used additional rings in segmental diaphyseal fractures or used olive compression wires across the fracture when additional stability was required. Hybrid fixation was the primary procedure in 25 patients and a secondary procedure, performed within eight weeks of injury, in 15. All patients went on to union in a mean of 45 weeks, but 10 required additional procedures such as bone-grafting, additional insertion of olive wire and soft-tissue procedures. Residual malunion in six patients required adjustment with frame fixation, with minimal clinical significance. We had three pin-tract infections and one deep infection, which resolved after sequestrectomy.

When choosing a fixation system, it must be taken into account that high-energy tibial fractures may be slow to unite and that deep infection is related to the degree of soft-tissue injury. We believe hybrid fixation is a safe and minimally invasive treatment option. Careful attention to reduction and soft-tissue management, followed by early functional rehabilitation, can reduce healing times.

The Orthofix acute correction template has been developed for multiplanar deformity corrections, with or without lengthening, using a monolateral external fixation system such as the limb reconstruction system (LRS). Pin placement is achieved by marrying the template onto the particular deformity in the frontal, sagittal and rotational planes, so that after the osteotomy the pins can be rearranged by manipulating the fragments to permit application of the standard Orthofix fixation system. The options of compression, dynamisation or lengthening through the osteotomy sites remain available should they be required in the reconstructive procedure.

We have found the template useful in correcting multiplanar deformities intra-operatively. This is followed by internal fixation and removal of the external fixator at the end of the procedure. Internal fixation of diaphyseal and metaphyseal osteotomies is achieved with intramedullary nailing and blade fixation respectively.

This technique simplifies complex procedures, following careful planning by accurate pin placement. The fragments are compressed before definitive internal fixation. The correct mechanical axis is checked radiologically before stable fixation.

Severe leg pain in a patient after total hip replacement was found to be caused by compression of the sciatic nerve by methylmethacrylate cement which had leaked from the acetabulum during fixation of the acetabular cup. The pain persisted for six years but was immediately relieved by removal of the cement mass.
