We have retrospectively reviewed the clinical and radiological results in 204 consecutive adult patients who had surgical correction of 70 late post-traumatic pelvic nonunions and 134 malalignments. The deformed pelvises were subdivided into united (true), unstable, ununited, and partially stable malalignments with heterotopic bone. The principal complaints were of pain, pelvic instability, sitting imbalance, and apparent limb-length discrepancy. After surgery, 195 patients (96%) achieved a primary union and 144 (71%) had slight, intermittent or no pelvic pain, while pelvic instability was entirely eliminated. Overall, 131 patients (64.2%) were extremely satisfied, 58 (28.4%) were satisfied and 15 (7.4%) were unsatisfied. After reconstruction of the malaligned pelvises, 67 results (50%) were anatomical, 47 (35%) were satisfactory and 20 (15%) were unsatisfactory. For a pelvic nonunion with local osteopenia and malalignment, stabilisation of all three pelvic columns is recommended. True pelvic (united) malunions were the most satisfactorily realigned and had the fewest complications. Ununited and unstable malalignments, especially those with heterotopic bone, had the poorest corrections and the most neurological complications. A therapeutic alternative, by the local resection of a symptomatic bony prominence, and fixation in situ of a posterior pelvic nonunion, gives highly effective symptomatic relief with fewer complications. Despite this, many patients had persistent low back pain

Aims

The hypothesis of this study was that bone peg fixation in the treatment of osteochondral lesions of the talus would show satisfactory clinical and radiological results, without complications.

We reviewed 110 patients with an unstable fracture of the pelvic ring who had been treated with a trapezoidal external fixator after a mean follow-up of 4.1 years. There were eight open-book (type B1, B3-1) injuries, 62 lateral compression (type B2, B3-2) and 40 rotationally and vertically unstable (type C1-C3) injuries. The rate of complications was high with loss of reduction in 57%, malunion in 58%, nonunion in 5%, infection at the pin site in 24%, loosening of the pins in 2%, injury to the lateral femoral cutaneous nerve in 2%, and pressure sores in 3%. The external fixator failed to give and maintain a proper reduction in six of the eight open-book injuries, in 20 of the 62 lateral compression injuries, and in 38 of the 40 type-C injuries. Poor functional results were usually associated with failure of reduction and an unsatisfactory radiological appearance. In type-C injuries more than 10 mm of residual vertical displacement of the injury to the posterior pelvic ring was significantly related to poor outcome. In 14 patients in this unsatisfactory group poor functional results were also affected by associated nerve injuries. In lateral compression injuries the degree of displacement of fractures of the pubic rami caused by internal rotation of the hemipelvis was an important prognostic factor. External fixation may be useful in the acute phase of resuscitation but it is of limited value in the definitive treatment of an unstable type-C injury and in type-B open-book injuries. It is usually unnecessary in minimally displaced lateral compression injuries

Aims

To compare complication-related reoperation rates following primary arthroplasty for proximal humerus fractures (PHFs) versus secondary arthroplasty for failed open reduction and internal fixation (ORIF).

We carried out a retrospective study to assess the clinical results of lengthening the fourth metatarsal in brachymetatarsia in 153 feet of 106 patients (100 female, six males) using three different surgical techniques. In one group lengthening was performed by one-stage intercalary bone grafting secured by an intramedullary Kirschner-wire (45 feet, 35 patients). In the second group lengthening was obtained gradually using a mini-external fixator after performing an osteotomy with a saw (59 feet, 39 patients) and in the third group lengthening was achieved in a gradual manner using a mini-external fixator after undertaking an osteotomy using osteotome through pre-drilled holes (49 feet, 32 patients). The mean age of the patients was 26.3 years (13 to 48). Pre-operatively, the fourth ray of the bone-graft group was longer than that of other two groups (p < 0.000). The clinical outcome was compared in the three groups. The mean follow-up was 22 months (7 to 55). At final follow-up, the mean lengthening in the bone-graft group was 13.9 mm (3.5 to 23.0, 27.1%) which was less than that obtained in the saw group with a mean of 17.8 mm (7.0 to 33.0, 29.9%) and in the pre-drilled osteotome group with a mean of 16.8 mm (6.5 to 28.0, 29.4%, p = 0.001). However, the mean time required for retention of the fixation in the bone-graft group was the shortest of the three groups. Patients were dissatisfied with the result for five feet (11.1%) in the bone-graft group, eight (13.6%) in the saw group and none in the pre-drilled osteotomy group (p < 0.000). The saw group included eight feet with failure of bone formation after surgery. Additional operations were performed in 20 feet because of stiffness (n = 7, all groups), failure of bone formation (n = 4, saw group), skin maceration (n = 4, bone-graft group), malunion (n = 4, bone-graft and saw groups) and breakage of the external fixator (n = 1, saw group). We conclude that the gradual lengthening by distraction osteogenesis after osteotomy using an osteotome produces the most reliable results for the treatment of fourth brachymetatarsia

Aims

Bone demonstrates good healing capacity, with a variety of strategies being utilized to enhance this healing. One potential strategy that has been suggested is the use of stem cells to accelerate healing.

We report the outcome of 19 children aged 5.2 to 13.2 years with 20 fractures of the femoral shaft requiring surgery, who were randomly assigned to have external fixation (EF) or flexible intramedullary nailing (FIN) (10 fractures each). The duration of the operation averaged 56 minutes for the EF group with 1.4 minutes of fluoroscopy, compared with 74 minutes and 2.6 minutes, respectively, for the FIN group. The early postoperative course was similar, but the EF group showed much more callus formation. The time to full weight-bearing, full range of movement and return to school were all shorter in the FIN group. The FIN complications included one transitory foot drop and two cases of bursitis at an insertion site. In the EF group there was one refracture, one rotatory malunion requiring remanipulation and two pin-track infections. At an average follow-up of 14 months two patients in the EF group had mild pain, four had quadriceps wasting, one had leg-length discrepancy of over 1 cm, four had malalignment of over 5°, and one had limited hip rotation. In the FIN group, one patient had mild pain and one had quadriceps wasting; there were no length discrepancies, malalignment or limitation of movement. Parents of the FIN group were more satisfied. We recommend the use of flexible intramedullary nailing for fractures of the femoral shaft which require surgery, and reserve external fixation for open or severely comminuted fractures

We describe the results of treatment of open fractures of the humerus, radius and ulna in 61 children. Most were due to low-energy trauma and were rarely associated with head or other injuries; 72% were Gustilo type I, 15% type II and 13% type III. Fifteen children (25%) had open diaphyseal, supracondylar or T-shaped fractures of the humerus. Arterial injuries occurred in two (13%) and nerve injuries in 7 (47%). All nerve injuries recovered spontaneously. The long-term results in 13 children were excellent or good in 11 (85%) and fair in two (15%). Forty-six children (75%) had open forearm fractures. Arterial injuries occurred in one (2%), nerve injuries in five (11%) and a compartment syndrome in five (11%). Ruptured radial and ulnar arteries and median and ulnar nerves were repaired in one child. All other nerve injuries resolved spontaneously. Early compartment release in five children prevented Volkmann's ischaemic contracture. Normal union occurred in only 36 children (78%). Delayed union, nonunion, malunion and refracture frequently complicated type-II and type-III fractures of the shafts of the radius and ulna. The long-term results in 38 children were excellent or good in 33 (87%), fair in 4 (11%) and poor in one (2%). The short-term results for open fractures of the humerus were better than for open fractures of the forearm, but the long-term results were similar being excellent or good in 86% of the children

Aims

Dual plating of distal femoral fractures with medial and lateral implants has been performed to improve construct mechanics and alignment, in cases where isolated lateral plating would be insufficient. This may potentially compromise vascularity, paradoxically impairing healing. This study investigates effects of single versus dual plating on distal femoral vascularity.

We describe the results of treatment of open tibial fractures in 92 children; 22 fractures were Gustilo type I, 51 type II and 19 type III. All children received tetanus prophylaxis, systemic antibiotics for 48 hours and thorough debridement and irrigation of the wound. Fifty-one wounds with minimal soft-tissue injury were closed primarily. The other 41 were initially left open; of these, 18 small wounds were allowed to heal secondarily and 23 larger wounds required split skin grafts or soft-tissue local or microvascular free flaps. Stable fractures were reduced and immobilised in an above-knee plaster cast (71%) and external fixation (28%) was used for unstable fractures, extensive soft-tissue injury and multiple injuries. Short-term complications included compartment syndrome (4%), superficial infection (8%), deep infection (3%), delayed union (16%), nonunion (7.5%) and malunion (6.5%): these incidences are similar to those reported in adults. Selective primary closure of wounds did not increase the incidence of infection. External fixation was associated with a greater occurrence of delayed and nonunion than plaster immobilisation, but this technique was used most often for the more severe injuries. Late review, at 1.5 to 9.8 years, showed a high incidence of continuing morbidity including pain at the healed fracture site (50%), restriction of sporting activity (23%), joint stiffness (23%), cosmetic defects (23%) and minor leg-length discrepancies (64%). Open tibial fractures in children are associated with a high incidence of early and late complications, which are more frequent in children with Gustilo type III injuries. The Gustilo classification was a useful guide for predicting the outcome and planning treatment

Aims

Fixation of osteoporotic proximal humerus fractures remains challenging even with state-of-the-art locking plates. Despite the demonstrated biomechanical benefit of screw tip augmentation with bone cement, the clinical findings have remained unclear, potentially as the optimal augmentation combinations are unknown. The aim of this study was to systematically evaluate the biomechanical benefits of the augmentation options in a humeral locking plate using finite element analysis (FEA).

Aims

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.

Aims

The aim of this study is to report the results of a case series of olecranon fractures and olecranon osteotomies treated with two bicortical screws.

Aims

Arthroplasty for end-stage hallux rigidus (HR) is controversial. Arthrodesis remains the gold standard for surgical treatment, although is not without its complications, with rates of up to 10% for nonunion, 14% for reoperation and 10% for metatarsalgia. The aim of this study was to analyze the outcome of a double-stemmed silastic implant (Wright-Medical, Memphis, Tennessee, USA) for patients with end-stage HR.

Aims

Cephalomedullary nails (CMNs) are commonly used for the treatment of intertrochanteric hip fractures. Total hip arthroplasty (THA) may be used as a salvage procedure when fixation fails in these patients. The aim of this study was to analyze the complications of THA following failed intertrochanteric hip fracture fixation using a CMN.
