Aims. No randomized comparative study has compared the extensile lateral approach (ELA) and sinus tarsi approach (STA) for Sanders type 2 calcaneal fractures. This randomized comparative study was conducted to confirm whether the STA was prone to fewer wound complications than the ELA. Methods. Between August 2013 and August 2018, 64 patients with Sanders type 2 calcaneus fractures were randomly assigned to receive surgical treatment by the ELA (32 patients) and STA (32 patients). The primary outcome was development of wound complications. The secondary outcomes were postoperative complications, pain scored of a visual analogue scale (VAS), American Orthopaedic Foot and Ankle Society (AOFAS) score, 36-item Short Form health survey, operative duration, subtalar joint range of motion (ROM), Böhler’s angle and calcaneal width, and posterior facet reduction. Results. Although four patients (12.5%) in the ELA groups and none in the STA group experienced complications, the difference was not statistically significant (p = 0.113). VAS and AOFAS score were significantly better in the STA group than in the ELA group at six months (p = 0.017 and p = 0.021), but not at 12 months (p = 0.096 and p = 0.200) after surgery. The operation time was significantly shorter in the STA group than in the ELA group (p < 0.001). The subtalar joint ROM was significantly better in the STA group (p = 0.015). Assessment of the amount of postoperative reduction compared with the uninjured limb showed significant restoration of calcaneal width in the ELA group compared with that in the STA group (p < 0.001). Conclusion. The ELA group showed higher frequency of wound complications than the STA group for Sanders type 2 calcaneal fractures even though this was not statistically significant.

Aims. This study aimed to investigate the clinical characteristics and outcomes associated with culture-negative limb osteomyelitis patients. Methods. A total of 1,047 limb osteomyelitis patients aged 18 years or older who underwent debridement and intraoperative culture at our clinic centre from 1 January 2011 to 31 December 2020 were included. Patient characteristics, infection eradication, and complications were analyzed between culture-negative and culture-positive cohorts. Results. Of these patients, 264 (25.2%) had negative cultures. Patients with a culture-negative compared with a culture-positive status were more likely to have the following characteristics: younger age (≤ 40 years) (113/264 (42.8%) vs 257/783 (32.8%); p = 0.004), a haematogenous aetiology (75/264 (28.4%) vs 150/783 (19.2%); p = 0.002), Cierny-Mader host A (79/264 (29.9%) vs 142/783 (18.1%); p < 0.001), antibiotic use before sampling (34/264 (12.9%) vs 41/783 (5.2%); p＜0.001), fewer taken samples (n＜3) (48/264 (18.2%) vs 60/783 (7.7%); p＜0.001), and less frequent presentation with a sinus (156/264 (59.1%) vs 665/783 (84.9%); p < 0.001). After initial treatments of first-debridement and antimicrobial, infection eradication was inferior in culture-positive osteomyelitis patients, with a 2.24-fold increase (odds ratio 2.24 (95% confidence interval 1.42 to 3.52)) in the redebridement rate following multivariate analysis. No statistically significant differences were found in long-term recurrence and complications within the two-year follow-up. Conclusion. We identified several factors being associated with the culture-negative result in osteomyelitis patients. In addition, the data also indicate that culture negativity is a positive prognostic factor in early infection eradication. These results constitute the basis of optimizing clinical management and patient consultations. Cite this article: Bone Joint J 2024;106-B(7):720–727

Aims. This study aimed to investigate the role of quantitative histological analysis in the diagnosis of fracture-related infection (FRI). Patients and Methods. The clinical features, microbiology culture results, and histological analysis in 156 surgically treated nonunions were used to stratify the likelihood of associated infection. There were 64 confirmed infected nonunions (one or more confirmatory criteria: pus, sinus, and bacterial growth in two or more samples), 66 aseptic nonunions (no confirmatory criteria), and 26 possibly infected nonunions (pathogen identified from a single specimen and no confirmatory criteria). The histological inflammatory response was assessed by average neutrophil polymorph (NPs) counts per high-power field (HPF) and compared with the established diagnosis. Results. Assuming a cut-off of over five neutrophils per high-power field to diagnose septic nonunion, there was 80% sensitivity and 100% specificity (accuracy 90%). Using a cut-off of no neutrophils seen in any high-power field to diagnose aseptic nonunion, there was a sensitivity of 85% and a specificity of 98% (accuracy 92%). Conclusion. Histology can be used in a bimodal fashion as a diagnostic test for FRI. The presence of more than five NPs/HPF had a positive predictive value for infected nonunion of 100%, while the complete absence of any NPs is almost always indicative of an aseptic nonunion (positive predictive value of 98%).

Background:. In 1931, Gaenslen reported treatment of haematogenous calcaneal osteomyelitis through an incision on the sole of the heel, without the use of antibiotics. We have modified his approach to allow shorter healing times and early mobilisation in a modern series of cases. Method:. Sixteen patients with Cierny-Mader Stage IIIB chronic osteomyelitis were treated with split-heel incision, calcaneal osteotomy, radical excision, local antibiotics, direct skin closure and parenteral antibiotics. 4 patients had diabetic foot infection with neuropathy, 5 had infection after open injuries, 4 had haematogenous osteomyelitis and 3 had Grade 4 pressure ulceration with bone involvement. 14 had sinuses/ulcers and 12 had undergone previous surgery. Primary outcomes were eradication of infection, time to sinus/ulcer healing, mobility and need for modified shoes. Results:. Mean hospital stay was 19.2 days (7–44). 14 patients had no recurrence of infection at final follow-up (minimum 12 months; mean 53 months). Ulcers healed between 4 and 15 weeks. 2 patients with recurrent infection required amputation. Of the 14 salvaged patients, 10 mobilised unaided. 9 required modified shoes. Conclusion:. This protocol gave effective control of infection, ulcer healing and mobilisation within an acceptable time, but amputation remains a risk

Prosthetic joint infections provide complex management, due to often-difficult diagnosis, need for multiple surgeries and increased technical and financial requirements. “2 in 1” single stage approaches have been advocated due to reduction in risks, costs and complications. This study aimed to investigate the results of single stage revision using metaphyseal sleeves for infected primary Total Knee Replacement (TKR). Prospective data was collected on all patients presenting with an infected primary TKR over an 8-year period (2009–17). All revision procedures were undertaken in a single stage using metaphyseal sleeves. 26 patients were included, 2 of which had previously failed 2 stage revision and 3 failed DAIR procedures. Mean age was 72.5. Mean BMI was 33.4. Median ASA 2. Mean time to revision was 3.5 years range 3 months to 12 years. Six patients had actively discharging sinuses at the time of surgery. Only 4 of the 26 patients had no positive microbiological cultures from deep tissue samples or joint aspirates. Only one patient has a recurrence of infection. This patient did not require further surgery and is treated on long term antibiotic suppression and is systemically well. There were statistically significant improvements in both the pain and function component of AKSS scores. There was no significant improvement in flexion, however mean extension and total range of movement both showed statistically significant improvements. Using Metaphyseal sleeves in single stage revision for infected TKR are safe and lead to an improvement in pain, function and have excellent efficacy for eradication of infection

Aim. The aim was to investigate the value of quantitative histological analysis in the diagnosis of fracture-related infection (FRI). Patients and Methods. The clinical features, microbiology culture results and histological analysis in 156 surgically treated non-unions were used to stratify the likelihood of associated infection. There were 64 confirmed infected non-unions (≥1 confirmatory criteria; pus, sinus and bacterial growth in ≥2 samples), 66 aseptic non-unions (no confirmatory criteria) and 26 possibly infected (pathogen identified from a single specimen and no confirmatory criteria). The histological inflammatory response was assessed by average neutrophil polymorphs (NPs) counts per high power field (HPF) and compared to the established diagnosis. Results. Assuming a cut-off of >5NPs/HPF for positive histological diagnosis, there was 80% sensitivity and 100% specificity (accuracy 90%). Using a cut-off of any NPs/HPF (>0) for negative histological diagnosis there was a sensitivity of 98% and a specificity of 85% (accuracy 92%). Conclusion. Histology can be used in a bimodal fashion as a diagnostic test for FRI. The presence of >5 NPs/HPF has a positive predictive value of 100%, while the complete absence of any NPs is almost always indicative of an aseptic non-union (negative predictive value: 98%)

Aims

Fracture-related infections (FRIs) are a devastating complication of fracture management. However, the impact of FRIs on mental health remains understudied. The aim of this study was a longitudinal evaluation of patients’ psychological state, and expectations for recovery comparing patients with recurrent FRI to those with primary FRI.

Objective. High grade hallux rigidus is a forefoot deformity characterized by a limitation of dorsiflexion of the first toe associated with pain, and severe damage of the first metatarsophalangeal joint. Most authors recommended resection arthroplasty or arthrodesis of the first metatarsophalangeal joint. The aim of this study was to present the results of our series of 42 consecutive cases of severe hallux rigidus treated by resection of the first metatarsal head and implant of a poly D-L lactic (PDLLA) bioreabsorbable spacer to promote the interposition of fibrous tissue to preserve the range of motion of the joint. Material and methods. Forty-two feet in 27 patients affected by high grade hallux rigidus were included in the study. Surgical treatment consisted of resection of the first metatarsal head and positioning of a poly D-L lactic acid (PDLLA) bioreabsorbable implant. Post-operative care consisted in gauze bandage of the forefoot, and immediate weight-bearing with talus shoes for 3 weeks. All patients were clinically and radiographically evaluated preoperatively and checked at a mean 6 (5–7) year follow-up. Results. No intraoperative complication occurred. No sinus formation were observed. All implants resulted well tolerated by the patients. Mean AOFAS score was 42±14 preoperatively and 81±9 postoperatively. Mean preoperative metatarsophalangeal joint ROM was 27±17 degrees and mean postoperative metatarsophalangeal joint ROM was 75±8 degrees. Conclusions. First metatarsophalangeal joint arthroplasty using bioreabsorbable implant demonstrated to be an effective surgical option for treatment of high grade hallux rigidus, thank to its ability to promote fibrous tissue formation during its reabsorption

Aims

The aim of this study was to evaluate the diagnostic value of preoperative serum CRP, white blood cell count (WBC), percentage of neutrophils (%N), and neutrophil to lymphocyte ratio (NLR) when using the fracture-related infection (FRI) consensus definition.

Aims

In this randomized study, we aimed to compare quality of regenerate in monolateral versus circular frame fixation in 30 patients with infected nonunion of tibia.

Aims

Many authors have reported a shorter treatment time when using trifocal bone transport (TFT) rather than bifocal bone transport (BFT) in the management of long segmental tibial bone defects. However, the difference in the incidence of additional procedures, the true complications, and the final results have not been investigated.

Aims

The aim of this prospective randomised controlled trial was to compare non-operative and operative management for acute isolated displaced fractures of the olecranon in patients aged ≥ 75 years.

In this retrospective observational cohort study, we describe 17 patients out of 1775 treated for various fractures who developed mycobacterium tuberculosis (MTB) infection after surgery. The cohort comprised 15 men and two women with a mean age of 40 years (24 to 70). A total of ten fractures were open and seven were closed. Of these, seven patients underwent intramedullary nailing of a fracture of the long bone, seven had fractures fixed with plates, two with Kirschner-wires and screws, and one had a hemiarthroplasty of the hip with an Austin Moore prosthesis. All patients were followed-up for two years. In all patients, the infection resolved, and in 14 the fractures united. Nonunion was seen in two patients one of whom underwent two-stage total hip arthroplasty (THA) and the other patient was treated using excision arthoplasty. Another patient was treated using two-stage THA. With only sporadic case reports in the literature, MTB infection is rarely clinically suspected, even in underdeveloped and developing countries, where pulmonary and other forms of TB are endemic. In developed countries there is also an increased incidence among immunocompromised patients. In this paper we discuss the pathogenesis and incidence of MTB infection after surgical management of fractures and suggest protocols for early diagnosis and management.

Aims

To compare the outcomes for trochanteric fractures treated with a sliding hip screw (SHS) or a cephalomedullary nail.

Aims

This is a prospective randomised study which compares the radiological and functional outcomes of ring and rail fixators in patients with an infected gap (> 3 cm) nonunion of the tibia.

Aims

The aim of this study was to identify risk factors for the failure of exchange nailing in nonunion of tibial diaphyseal fractures.

Our aim was to compare polylevolactic acid screws with titanium screws when used for fixation of the distal tibiofibular syndesmosis at mid-term follow-up. A total of 168 patients, with a mean age of 38.5 years (18 to 72) who were randomly allocated to receive either polylevolactic acid (n = 86) or metallic (n = 82) screws were included. The Baird scoring system was used to assess the overall satisfaction and functional recovery post-operatively. The demographic details and characteristics of the injury were similar in the two groups. The mean follow-up was 55.8 months (48 to 66). The Baird scores were similar in the two groups at the final follow-up. Patients in the polylevolactic acid group had a greater mean dorsiflexion (p = 0.011) and plantar-flexion of the injured ankles (p < 0.001). In the same group, 18 patients had a mild and eight patients had a moderate foreign body reaction. In the metallic groups eight had mild and none had a moderate foreign body reaction (p <  0.001). In total, three patients in the polylevolactic acid group and none in the metallic group had heterotopic ossification (p = 0.246).

We conclude that both screws provide adequate fixation and functional recovery, but polylevolactic acid screws are associated with a higher incidence of foreign body reactions.

We have managed 21 patients with a fracture of the tibia complicated by bone and soft-tissue loss as a result of an open fracture in 10, or following debridement of an infected nonunion in 11, by resection of all the devitalised tissues, acute limb shortening to close the defect, application of an external fixator and metaphyseal osteotomy for re-lengthening. The mean bone loss was 4.7 cm (3 to 11). The mean age of the patients was 28.8 years (12 to 54) and the mean follow-up was 34.8 months (24 to 75).

All the fractures united with a well-aligned limb. The mean duration of treatment for the ten grade-III A+B open fractures (according to the Gustilo-Anderson classification) was 5.7 months (4.5 to 8) and for the nonunions, 7.6 months (5.5 to 12.5). Complications included one refracture, one transient palsy of the peroneal nerve and one equinus contracture of 10°.

Between June 1999 and May 2003 we undertook direct primary closure of the skin wounds of 173 patients with Gustilo and Anderson grade-IIIA and grade-IIIB open fractures. These patients were selected from a consecutive group of 557 with type-III injuries presenting during this time. Strict criteria for inclusion in the study included debridement within 12 hours of injury, no sewage or organic contamination, no skin loss either primarily or secondarily during debridement, a Ganga Hospital open injury skin score of 1 or 2 with a total score of ten or less, the presence of bleeding skin margins, the ability to approximate wound edges without tension and the absence of peripheral vascular disease. In addition, patients with polytrauma were excluded.

At a mean follow-up of 6.2 years (5 to 7), the outcome was excellent in 150 (86.7%), good in 11 (6.4%) and poor in 12 (6.9%). A total of 33 complications occurred in 23 patients including superficial infection in 11, deep infection in five and the requirement for a secondary skin flap in three. Six patients developed nonunion requiring further surgery, one of whom declined additional measures to treat an established infected nonunion.

Immediate skin closure when performed selectively with the above indications proved to be a safe procedure.

We undertook a retrospective study of 50 consecutive patients (41 male, 9 female) with an infected nonunion and bone defect of the femoral shaft who had been treated by radical debridement and distraction osteogenesis. Their mean age was 29.9 years (9 to 58) and they had a mean of 3.8 (2 to 19) previous operations. They were followed for a mean of 5.9 years (2.0 to 19.0). The mean duration of the distraction osteogenesis was 24.5 months (2 to 39). Pin-track infection was observed in all patients. The range of knee movement was reduced and there was a mean residual leg-length discrepancy of 1.9 cm (0 to 8) after treatment. One patient required hip disarticulation to manage intractable sepsis. In all, 13 patients had persistant pain. Bony union was achieved in 49 patients at a mean of 20.7 months (12 to 35).

Although distraction osteogenesis is commonly used for the treatment of infected femoral nonunion with bone defects, it is associated with a high rate of complications.
