Fixation Techniques

The valgus-impacted (VI) 4-part fractures are a subset of fractures of the proximal humerus with a unique anatomic configuration characterized by a relatively lower incidence of avascular necrosis after operative intervention. We systematically reviewed clinical studies assessing the benefits and harms of least possible fixation techniques (LPFT) for this unique fracture type. Such information would be potentially helpful in developing an evidence-based approach in the management of these complex injuries. We performed analytic searches of PubMed, Embase, Web of Science, Google Scholar and the Cochrane Library, restricting it to the years 1991-2014. Included studies had to describe outcomes and complications after primary osteosynthesis with any type of LPFT apart from plate-screws and intramedullary nailing. Eligibility criteria were also included English language, more than 5 cases, minimum follow up of one year and report of clinical outcome using at least one relevant score (Constant, Neer or ASES). Based on 292 database hits we identified 12 eligible studies including 190 four-part valgus impacted fractures in 188 patients. All eligible studies were case series composed of min 8 to max 45 patients per study. The gender distribution was 60% (112) female and 40% (76) male. The average age of the patients at the time of injury was 54.5 years. In 8/12 studies an open reduction was used for fracture fixation using different surgical techniques including KW, cerclage wires, cannulated screws and osteosutures. Closed reduction and percutaneous fixation was used in 4 studies. Mean follow-up time ranged from 24 to 69 months. A good functional outcome (constant score >80) was reported in 9/12 studies. The most common complication was avascular necrosis of the humeral head with an overall incidence of 11% (range, 0-26.3%). Total avascular necrosis (AVN) was found in 15/188 patients (7.9%) and was more common in percutaneous techniques and partial AVN in 6/188 (3.1%) being more common in open techniques. The overall re-operation rate was very low (3.7%). Insufficient study designs cannot provide definite treatment recommendations and quantitative data synthesis of outcome. In general, LPFT for 4-part VI fractures leads to satisfactory outcomes with low incidence of complications. A considerable risk of biases can be attributed to fracture classification, proper radiological control, mean age of patients, mixed types of fixation methods, nonage adjusted clinical scoring and small follow up periods. These factors are discussed in detail. Level of evidence: systematic review of literature (level IV) as most of the studies were level IV.

Category: Hindfoot Introduction/Purpose: Avascular necrosis (AVN) of the talus is commonly caused by trauma and often requires surgical management. It is recommended that healthy patients, in pre-collapse stages, undergo joint preservation procedures. Good results have been published in patients in pre-collapse stages who undergo vascularized bone grafting. Although many graft options exist, more recently the medial femoral condyle (MFC) free vascularized graft has been introduced. This graft typically utilizes vascularized corticoperiosteal bone but can be modified to the use of solely periosteum, which theoretically decreases morbidity and operative time. There is limited research on the periosteal-only MFC flap to treat AVN of the talus. We present a case series and surgical technique utilizing a periosteal vascularized pedicle graft to teat AVN of the talus. Methods: A surgical technique is presented, in addition to a retrospective review of AVN of the talus of 6 lower extremities. Treatment included talus core decompression along with an ipsilateral medial femoral condyle free vascularized periosteal graft. All patients included were in the pre-collapse stage. Short-term clinical outcome measures of Foot & Ankle Ability Measure- Activities of Daily Living (FAAM-ADL) subscale, Short Form-12 (SF-12), and Visual Analog Scale (VAS) for pain were recorded for all patients post-operatively. Paired T-tests were used to compare pre- and post-operative functional scores. Post-operative MRIs were reviewed by a musculoskeletal radiologist. Results: The causes of AVN included trauma (2/6, 33%), sepsis (2/6, 33%), and idiopathic (2/6, 33%). Post-operative FAAM-ADL (P=0.004) and VAS (P=0.003) scores showed statistically significant improvement from pre-operative values at an average of 16.0 months (range, 6-28 months) after surgery. Additionally, all patients (100%) reported being “very satisfied” with their surgical outcome. There was 1 minor complication, with one patient reporting minimal paresthesias following surgery. Post-operative MRIs, taken at a mean of 12.7 months, demonstrated both resolution of marrow edema and soft tissue inflammation surrounding the areas of AVN and a lack of AVN progression in 100% of lower extremities, when compared to pre-operative MRIs. Conclusion: Medial femoral condyle free vascularized periosteal graft is a complex procedure which requires a team comprised of a foot & ankle surgeon and a plastic/hand surgeon familiar with microvascular surgery. This study shows promising initial results for the treatment of an extremely challenging diagnosis: AVN of the talus. Long-term, prospective studies are needed to confirm the findings presented in the current study.

Introductions: Avascular necrosis and non-union are common but when the neck of femur fracture in adult is neglected, the chances of complications rises. Among various treatment options, we report the outcome of free fibular strut graft along with two cannulated hip screws in neglected fracture neck of femur. Methods: The outcome analysis of ‘fibular strut graft and two cannulated hip screws’ was conducted in patients with fracture neck of femur who presented at least three weeks after the time of injury, during August 2008 to December 2017, at Lumbini Zonal Hospital and Lumbini Hospital Technical College, Butwal, Nepal. All adult patients aged 18 to 60 years were included. Outcome variables were healing of fracture (union, delayed union, non-union), avascular necrosis and Harris Hip Score (HHS). Results: Out of 20 fractures, 17 (85%) united uneventfully, 2 (10%) had delayed union and 1 (5%) nonunion. We had 3 (15%) avascular necrosis of femoral head. The HHS was excellent in 8 (40%), good in 4 (20%), fair in 6 (30%) and poor in 2 (10%). Conclusions: Fibular Strut graft with two hip screws resulted in fracture union and improved hip functions in patients with neglected fracture of neck of femur.

Aims Preserving growth following limb-salvage surgery of the upper limb in children remains a challenge. Vascularized autografts may provide rapid biological incorporation with the potential for growth and longevity. In this study, we aimed to describe the outcomes following proximal humeral reconstruction with a vascularized fibular epiphyseal transfer in children with a primary sarcoma of bone. We also aimed to quantify the hypertrophy of the graft and the annual growth, and to determine the functional outcomes of the neoglenofibular joint. Patients and Methods We retrospectively analyzed 11 patients who underwent this procedure for a primary bone tumour of the proximal humerus between 2004 and 2015. Six had Ewing’s sarcoma and five had osteosarcoma. Their mean age at the time of surgery was five years (two to eight). The mean follow-up was 5.2 years (1 to 12.2). Results The overall survival at five and ten years was 91% (confidence interval (CI) 95% 75% to 100%). At the time of the final review, ten patients were alive. One with local recurrence and metastasis died one-year post-operatively. Complications included seven fractures, four transient nerve palsies, and two patients developed avascular necrosis of the graft. All the fractures presented within the first postoperative year and united with conservative management. One patient had two further operations for a slipped fibular epiphysis of the autograft, and a hemi-epiphysiodesis for lateral tibial physeal arrest. Hypertrophy and axial growth were evident in nine patients who did not have avascular necrosis of the graft. The mean hypertrophy index was 65% (55% to 82%), and the mean growth was 4.6 mm per annum (2.4 to 7.6) in these nine grafts. At final follow-up, the mean modified functional Musculoskeletal Tumour Society score was 77% (63% to 83%) and the mean Toronto Extremity Salvage Score (TESS) was 84% (65% to 94%). Conclusion Vascularized fibular epiphyseal transfer preserves function and growth in young children following excision of the proximal humerus for a malignant bone tumour. Function compares favourably to other limb-salvage procedures in children. Longer term analysis is required to determine if this technique proves to be durable into adulthood.
