Role of posterior stabilisation in the management of tuberculosis of the dorsal and lumbar spine

We present a prospective study of patients with tuberculosis of the dorsal, dorsolumbar and lumbar spine after combined anterior (radical debridement and anterior fusion) and posterior (instrumentation and fusion) surgery. The object was to study the progress of interbody union, the extent of correction of the kyphosis and its maintenance with early mobilisation, and the incidence of graft and implant-related problems. The American Spinal Injury Association (ASIA) score was used to assess the neurological status. The mean preoperative vertebral loss was highest (0.96) in the dorsal spine. The maximum correction of the kyphosis in the dorsolumbar spine was 17.8 degrees. Loss of correction was maximal in the lumbosacral spine at 13.7 degrees. All patients had firm anterior fusion at a mean of five months. The incidence of infection was 3.9% and of graft-related problems 6.5%. We conclude that adjuvant posterior stabilisation allows early mobilisation and rehabilitation. Graft-related problems were fewer and the progression and maintenance of correction of the kyphosis were better than with anterior surgery alone. There is no additional risk relating to the use of an implant either posteriorly or anteriorly even when large quantities of pus are present.

Treatment of haematogenous pyogenic vertebral osteomyelitis by single-stage anterior debridement, grafting of the defect and posterior instrumentation

Anterior debridement, grafting of the defect and posterior instrumentation as a single-stage procedure is a controversial method of managing pyogenic vertebral osteomyelitis. Between 1994 and 2005, 37 patients underwent this procedure at our hospital, of which two died and three had inadequate follow-up. The remaining 32 were reviewed for a mean of 36 months (12 to 66). Their mean age was 48 years (17 to 68). A significant pre-operative neurological deficit was present in 13 patients (41%). The mean duration of surgery was 285 minutes (240 to 360) and the mean blood loss was 900 ml (300 to 1600). Pyogenic organisms were isolated in 21 patients (66%). All patients began to mobilise on the second post-operative day. The mean hospital stay was 13.6 days (10 to 20). Appropriate antibiotics were administered for 10 to 12 weeks. Early wound infection occurred in four patients (12.5%), and late infection in two (6.3%). At final follow-up, the infection had resolved in all patients, neurological recovery was seen in ten of 13 (76.9%) and interbody fusion had occurred in 30 (94%). The clinical outcome was excellent or good in 30 patients according to Macnabs criteria. This surgical protocol can be used to good effect in patients with pyogenic vertebral osteomyelitis when combined with appropriate antibiotic therapy.

Open intramedullary nailing in neglected femoral diaphyseal fractures

INTRODUCTION Neglected femoral diaphyseal fractures are not uncommon in developing nations however there is a paucity of literature in this regard. Due to lack of effective traction, reduction or immobilisation these fractures are invariably associated with shortening and adjacent joint stiffness, presenting a challenging problem to the treating surgeon. The socioeconomic constraints in our society which result in patients seeking non-medical forms of treatment in the first place also warrant the need for an economically viable, simple effective form of treatment which can be carried out in a less advanced setup, gives reliable outcomes and allows early return to work. METHODS Eleven patients with neglected or late presenting femoral diaphyseal fractures were considered for the study. All patients underwent open intramedullary nailing, bone grafting and manipulation of the knee under anaesthesia. Iliac crest graft was harvested when local callus did not suffice. All patients received a supervised regimen of physiotherapy. Patients were followed up clinically and with plain radiographs at 6 weeks and 3 months to assess union and at monthly intervals thereafter. RESULTS The mean patient age was 28.8 years (15-48). The mean delay in presentation was 14 weeks (3-32 weeks). The mean shortening was 3.8 cm with four fractures showing signs of malunion. Five patients were given preoperative traction and bone resection was performed in only one patient. The mean hospital stay was 11 days (5-25 days). One patient was lost to follow up, of the remaining 10 patients all united at a mean of 11.9 weeks with 7 patients regaining full range of motion. The mean knee range of motion was 142.5 degrees . There were no wound related or neurological complications. One patient had a patellar tendon rupture which was repaired and another required dynamisation and bone marrow injection for delayed union. CONCLUSION We conclude that the treatment of neglected femoral diaphyseal fractures with open intramedullary nailing and bone grafting followed by manipulation of the knee with preoperative traction in selected cases is a satisfactory method of treatment showing reliable bony union however knee mobilisation should be undertaken with caution.

Reconstruction of open contaminated achilles tendon injuries with soft tissue loss.

BACKGROUND Open achilles tendon injuries, present a complex problem to the treating surgeon especially if associated with tendon and soft tissue loss. We present eight such patients treated with tendon repair/reconstruction and reverse flow sural artery flap for soft tissue cover. PATIENTS Eight patients (age, 12-64 years) with a spectrum of open tendo-achilles injuries of acute and chronic (infected), including loss of tendon of up to 10 cm, tendon defects with no distal attachment and one with partial loss of the calcaneum were treated between November 2005 and July 2006. Two of them had significant medical comorbid factors. The skin defect measured after debridement ranged from 6 x 5 cm to 15 x 10 cm. The tendon injuries were sutured directly when possible or sutured to bone if avulsed from the calcaneum. They were otherwise reconstructed using the central part of the proximal segment. A reverse sural artery was used to provide soft tissue cover. RESULTS All flaps survived. All patients had a normal gait, were able to stand on tip toes, had active plantar flexion and had returned to their original occupation 4 months after reconstruction. They had full range of movement at the ankle. One diabetic patient had terminal necrosis of the flap that required a split skin graft. He developed a late infection which did not compromise the functional result. CONCLUSION In the management of complex tendo-achilles injuries with tendon and soft tissue loss, radical debridement, single stage tendon reconstruction, and reverse flow sural artery flap gives good functional outcome. This gives consistent results across a spectrum of open tendo-achilles injury.

Disseminated rhinosporidiosis destroying the talus: a case report

Rhinosporidiosis is a chronic granulomatous fungal disease caused by Rhinosporidiosis seeberi. It usually affects the mucocutaneous tissue of the nose; bone involvement is rare. We report the clinical features, diagnosis, and management of rhinosporidiosis involving the face, forehead, and right foot. As antimicrobial therapy was ineffective, a below-knee amputation was performed.

Fracture neck of femur in haemophilia A – experience from a cohort of 11 patients from a tertiary centre in India

Summary. We describe here the management of eleven patients with fracture neck of femur. Excepting one patient all had severe haemophilia A. Nine patients were less than 50 years of age. Eight out of eleven patients had fracture after trivial trauma. Nine patients had closed reduction and one patient open reduction. The patient with non union had a Valgus osteotomy. All fractures united. The average time to union was 11 weeks (range:8–16). We followed either a low dose intermittent or a low dose continuous infusion factor support protocol for the management of these patients. The median dose of factor support was 252 u/kg (range: 136–580). The average duration of factor support was 9 days (range: 7–10). Two patients had aggravation of pre existing knee stiffness following post operative immobilisation. No other major complication was observed in this cohort of patients. To conclude, management of fracture neck of femur in patients with haemophilia is no different from general population if an adequate haemostasis is achieved.

Non-vascularised fibular graft as an intramedullary strut for infected non-union of the humerus

Purpose. To review outcomes of 7 patients who underwent revision surgery for infected non-union of the humerus using a fibular graft as an intramedullary strut. Methods. Records of 7 men aged 29 to 59 (mean, 40) years with humeral diaphyseal infected nonunion who underwent fixation using a compression plate and a non-vascularised fibular graft as an intramedullary strut were reviewed. The mean number of previous surgeries was 2.7 (range, 2–4). Three of the patients had active draining sinuses previously. Their C-reactive protein levels were normal and tissue cultures negative. The remaining 4 patients had active draining sinuses. They first underwent implant removal and debridement. Tissue cultures confirmed infection in 3 of them. The mean duration between debridement and the index surgery was 5 (range, 3–10) months. Results. The mean length of the fibulae harvested was 13 (range, 12–15) cm. All 7 non-unions healed. The mean time to healing was 5.4 (range, 4–8) months. The mean follow-up period was 15 (range, 13–24) months. All patients had weakness of the extensor hallucis longus, which improved to near normal at month 3. There was no donor-site morbidity. Three patients with active infection at presentation underwent repeat surgery. Two of them had wound washouts, and their non-unions went on to heal successfully; one underwent implant removal after union due to an active sinus. Six of the patients returned to their pre-injury activity level, and one endured a brachial plexus injury. Conclusion. Fixation using a compression plate and a non-vascularised fibular graft as an intramedullary strut achieved good outcome for infected non-union of the humerus despite prior multiple failed surgeries.

Experience of using local flaps to cover open lower limb injuries at an Indian trauma center

Background: Optimal care of open, high-velocity, lower limb injury requires surgical skills in debridement, skeletal stabilization, and in providing appropriate soft tissue cover. Timely coordination between orthopedic and plastic surgeons, though ideal, is often difficult. In our center, orthopedic surgeons undertake comprehensive treatment of open fractures including soft tissue cover. We reviewed the results of the local flaps of lower limb, done by orthopedic surgeons. Materials and Methods: We retrospectively reviewed the results of the lower limb flaps done between January 2005 and December 2006. All flaps done at and below the level of knee were included. Results: There were 105 patients with 120 flaps during this period. Two patients with two flaps were lost to follow-up. The average age was 32 years. Sixty-four patients had Type IIIB Gustilo and Anderson injuries. Thirty-nine patients had isolated soft tissue injuries. The indications for flaps were exposed bone, tendon, and joint in 45, 11, and 12, respectively, or a combination in 35 patients. The flaps done were 51 reverse sural artery, 35 gastrocnemius, 25 local fasciocutaneous, and seven foot flaps. The flap dimensions ranged from 2 × 2 to 30 × 15 cm. Ninety-three flaps (79%) healed primarily. Among 25 flaps (21%) with necrosis, 14 flaps required secondary split skin graft for healing, while the other nine flaps healed without further surgery. Conclusion: Appropriate soft tissue cover provided by orthopedic surgeons can help in providing independent, composite care of lower limb injuries.

Malunited calcaneal fracture fragments causing tarsal tunnel syndrome: A rare cause

This is a report of tarsal tunnel syndrome (TTS) due to a specific malunited calcaneal fracture fragment in a 46-year-old man. He was treated non-operatively for extra-articular calcaneal fracture. Four months later he presented with pain, tingling and hypoaesthesia over the medial aspect of the heel. He had a positive Tinels sign and a positive dorsiflexion-eversion test. Radiography revealed malunited calcaneal fracture along medial wall producing bony prominence. The tarsal tunnel was surgically decompressed by excising the malunited fragments. The branches of the posterior tibial nerve were stretched over these fragments intra-operatively. There was symptomatic improvement with surgical excision of the fragment, however, the hypoesthesia did not resolve completely. Appropriate initial treatment will help to prevent this complication.

Preoperative embolisation in benign bone tumour excision

Purpose. To assess the role of preoperative embolisation in benign bone tumour excision. Methods. 3 men and 3 women aged 19 to 35 (mean 23) years with either a giant cell tumour or an aneurysmal bone cyst in limb girdle sites underwent preoperative embolisation a day prior to wide local excision by the same surgeon. Tumour size, blood loss, wound healing, infection, and tumour recurrence were assessed. Results. The mean total blood loss was 391 (range, 100–980) ml. No blood transfusion was needed. No patient had any surgery- or embolisation-associated complication. No tumour recurred within a minimum 5-year follow-up. All patients had satisfactory limb function. Conclusion. Preoperative embolisation is useful in the management of vascular and aggressive bone tumours located at limb girdle sites where a tourniquet cannot be used.
