Early radial head excision for displaced and comminuted radial head fractures: considerations and concerns at long-term follow-up.

Objectives: The aim of this study is to retrospectively review the outcomes of patients with comminuted radial head fractures surgically treated with early radial head excision. Design: Retrospective follow-up study. Setting: University orthopaedic trauma center. Patients: Forty-two patients with unilateral, isolated, closed, displaced, or comminuted radial head fracture (Mason type 2-10, Type 3-32). Intervention: Early radial head excision. Main Outcome Measurements: Patients were clinically and radiographically evaluated at an average follow-up of 18 years. The uninjured contralateral limb was used as a comparison. Clinical evaluation was rated using the Broberg and Morrey system, the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, and the visual analog scale (VAS) for pain. Results: At last follow-up, 36 patients had no complaints, whereas six admitted to occasional pain. The mean Broberg and Morrey score was 91.2 ± 6.3, and the mean Disabilities of the Arm, Shoulder and Hand score was 10.1 ± 8.8. Conclusion: Early radial head excision represents a viable option in case of displaced and comminuted fractures. According to the results of this study, it demonstrated a high rate of good results and patient satisfaction, a quick recovery after surgery, and a low rate of complications with durable results at long-term follow-up. Level of Evidence: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Total hip arthroplasty in developmental hip dysplasia using cementless tapered stem. Results after a minimum 10-year follow-up.

Acetabular and femoral abnormalities make total hip arthroplasty in developmental hip dysplasia a challenging procedure. We present details of long-term follow-up of a series of patients affected by developmental hip dysplasia treated with total hip arthroplasty using a cementless tapered stem. Thirty-five hips in 20 patients (18 women and 2 men) aged between 44 and 60 years (mean 51 years) were observed. Clinical evaluation was conducted using the Harris Hip Score (HHS). Radiographic evaluation consisted in standard anteroposterior and axial view radiographs of the hip. According to Crowes classification, 25 hips had grade 2 and 10 hips grade 3 dysplasia. All patients were treated with total hip arthroplasty using a cementless tapered stem (Wagner Cone Prosthesis™). After surgery the patients were clinically and radiographically evaluated at 1, 2, 3, 6 and 12 months and annually thereafter. The average follow-up was 12 years (range 10–14 years). The average HHS was 57±7 (range 45–66) preoperatively, 90±7 (range 81–100) 12 months after surgery and 90±6 (range 83–100) at last follow-up. Radiographic evaluation demonstrated excellent osseointegration of the implants in most cases. Signs of bone resorption were present in 5 hips, but no evidence of loosening was observed and none of the implants have been revised. The tapered stem achieved adequate stability and orientation, and may be a suitable option for total hip arthroplasty for arthritis following developmental hip dysplasia.

Surgical Treatment of Cavus Foot in Charcot-Marie-Tooth Disease: A Review of Twenty-four Cases

Charcot-Marie-Tooth disease is the single most common diagnosis associated with cavus foot. The imbalance involving intrinsic and extrinsic muscles has been suggested as the main pathogenetic cause of cavus foot in this disease. The goal of surgical treatment is to correct the deformity to obtain a plantigrade foot. In the presence of a flexible deformity and the absence of degenerative arthritis, preserving as much as possible of the overall range of motion of the foot and ankle is advisable. Twenty-four cavus feet in twelve patients with Charcot-Marie-Tooth disease were included in the study. Clinical evaluation was summarized with the Maryland Foot Score. Radiographic evaluation assessed calcaneal pitch, Meary angle, Hibb angle, and absence of degenerative joint changes. Only patients who had a flexible deformity, with varus of the heel reducible in the Coleman-Andreasi test, and did not have degenerative joint arthritis were included in this study. Surgical treatment consisted in plantar fasciotomy, midtarsal osteotomy, extensor hallucis longus tendon transfer to the first metatarsal (Jones procedure), and dorsiflexion osteotomy of the first metatarsal. Mean follow-up was six years (range, two to thirteen years). The mean Maryland Foot Score was 72 preoperatively and 86 postoperatively. The postoperative result was rated as excellent in twelve feet (50%), good in ten (42%), and fair in two (8%). Mean calcaneal pitch was 34° preoperatively and 24° at the time of the latest follow-up, the mean Hibb angle was 121° preoperatively and 136° postoperatively, and the mean Meary angle was 25° preoperatively and 2° postoperatively. Plantar fasciotomy, midtarsal osteotomy, the Jones procedure, and dorsiflexion osteotomy of the first metatarsal yielded adequate correction of flexible cavus feet in patients with Charcot-Marie-Tooth disease in the absence of fixed hindfoot deformity. The fact that the improvement in the outcome score was only modest may be attributable to the lack of motor balance.

Single level cervical fusion by an anterior approach using autologous bone graft influences the adjacent levels degenerative changes: clinical and radiographic results at 10-year minimum follow-up

IntroductionCervical degenerative pathology can produce pain and disability and, in case of failure of conservative treatment surgery is indicated.Materials and methods107 patients affected by single level cervical degenerative pathology were surgically treated by Cloward procedure. On radiographs, the sagittal segmental alignment (SSA) of the affected level and sagittal alignment of the cervical spine were measured.Results Preoperatively, mean SSA was 0.6° and at the last follow-up 1.8°. In particular, adjacent-level degeneration occurred more frequently in Group A than in Group B.Conclusion Lordotic SSA angle can be considered a protective factor against adjacent-level degeneration.

Surgical treatment of hallux valgus associated with flexible flatfoot during growing age

PurposeDuring growth, hallux valgus could present associated with flatfoot. Considering the current disagreement about correction of hallux valgus during growth and the lack of reports about simultaneous correction of hallux valgus associated with flexible flatfoot, we present simultaneous treatment of both deformities during growth combining subtalar arthroeresis and SERI first metatarsal osteotomy, reporting results at an average five-year follow-up.MethodsThirty-two children (64 feet, age range 8–12 years) affected by hallux valgus associated with flexible flatfoot underwent surgical treatment combining SERI first metatarsal osteotomy and subtalar arthroereisis with bioabsorbable endorthotic implant. Clinical evaluation was summarized with AOFAS score, and standard standing radiographs were performed.ResultsAOFAS score ranged from 86 ± 2 to 98 ± 2 (hindfoot) and from 80 ± 4 to 98 ± 2 (forefoot). HVA ranged from 21° ± 2 to 5° ± 2, IMA from 14° ± 2 to 7° ± 2, DMAA from 18° ± 2 to 2° ± 2, and Meary’s angle from 162° ± 11 to 175° ± 4. Complications included one case of delayed wound healing, inflammatory skin reaction around the outlet of the percutaneous Kirschner wire in two cases, displacement of the endorthotic implant in one case, and a second surgery to replace the implant.ConclusionsSERI osteotomy and subtalar arthroereisis resulted in an effective, technically simple and easily combined approach, with a high rate of good results and low rate of complications at mid-term follow-up. These techniques performed simultaneously represent a viable option in case of hallux valgus associated with flexible flatfoot during growth. Nevertheless, considering the limitations of this study, we believe that a larger case series and a longer follow-up should be desirable.

Wound drainages in total hip arthroplasty: to use or not to use? Review of the literature on current practice

Aim of this study is to analyze data reported in literature concerning the efficacy of using wound low-vacuum suction drainages in orthopedic surgery after total hip arthroplasty. We analyzed studies concerning the use of drainages in prosthetic hip replacement surgery, performing our research through Pubmed, Cochrane database and Google Scholar, and selecting the ones evaluating the following parameters: bleeding, the need for blood transfusions, number or reinforcement of post-operative medications, length of hospitalization, functional results, periprosthetic and surgical wound infection, post-operative hematoma. Our review did not show any demonstrated advantage from the use of wound drainages in total hip arthroplasty. Moreover, some studies enlighted a possible complication related to their employment, represented by the greater need for blood transfusions. Despite the absence of a statistically demonstrated positive influence on wound outcome using suction drains after total hip replacement, many orthopedic surgeons still recommend using drainages, just because there is no certified proof of a negative effect.

Surgical treatment of complex tibial plateau fractures by closed reduction and external fixation. A review of 32 consecutive cases operated

Complex tibial plateau fractures are a challenge in trauma surgery. In these fractures it is necessary to anatomically reduce the articular part of the fracture and to obtain stable fixation. The aim of this study is to review the results of a surgical technique consisting of fluoroscopic closed reduction and combined percutaneous internal and external fixation. Thirty-two complex tibial plateau fractures in 32 patients were included. Twenty-one fractures were closed, 4 were open Gustilo grade I, 3 were Gustilo grade II and 4 were Gustilo grade III. The mean age was 37.8 years (range 21–64 years). Surgery was performed with patients in transcalcaneal traction and the knee flexed at 30° was used. Through a 1-cm incision centred over the tibial metaphysis of the tibia, a 3.2-mm hole was drilled in the antero-medial tibial aspect. The tibial plateau fracture fragments were elevated using either 1 or 2 curved Kirschner wires under fluoroscopy to control the reduction. Then the fragments were fixed with 2 cannulated AO screws inserted through small incisions into the medial aspect of the tibial plateau. Knee rehabilitation started postoperatively. Weight bearing started after 8–12 weeks depending upon the radiographic appearance. All external fixators were removed in outpatient facilities. All patients were clinically and radiographically evaluated at a mean follow-up of 48 months (range 38–57 months). Clinical results were evaluated according to the Knee Society clinical score. Average healing time was 24 weeks (range 18–29 weeks). In 1 patient a non-union occurred. This patient was treated with open reduction and plate fixation. In 2 patients a varus knee deformity occurred and a surgical correction was performed. There were no surgical complications. Mean knee range of motion was 105° (range 75–125°) and mean Knee Society clinical score was 89. Twenty-five results were scored as excellent, 4 good, 2 fair and 1 poor. Using this technique there is limited soft tissue damage and virtually no periosteum damage to the fracture fragments. However anatomical reconstruction of the joint can be obtained. Furthermore knee rehabilitation can be started immediately after surgery. We think that these factors were responsible for the optimal clinical long-term results.

The clubfoot over the centuries.

The aim of this paper is to review all treatment methods of the clubfoot over the years through the documentation present in the literature and art with the aim of better understanding the pathoanatomy of the deformity, but to also clarify factors that allow a safe, logical approach to clubfoot management. The initial part of this paper traces the most representative iconographic representations of clubfoot in history to describe how his presence was witnessed since ancient times. Hippocrates, the father of medicine, was the first to present written references about treatment methods of clubfoot. After the dark period of the Middle Ages, during the Renaissance, there were more detailed studies on the disease, with the creation of the first orthopedic orthotics, designed to correct the deformity with the help of famous names in medicines history. In the XVIII century, as we witness the birth of orthopedics as a distinct discipline in medicine, more and more brilliant minds developed complex orthoses and footwear with the aim of obtaining a proper correction of the deformity. In the last part of the paper, there is a description of the main surgical techniques developed over the years until the return to conservative treatment methods such as the Ponseti method, internationally recognized as the gold standard of treatment, despite the presence of some unresolved issues such as the possible recurrence of the disease.

Two-stage surgical treatment for septic non-union of the forearm

AIM To investigate the effectiveness of a two-stage surgical procedure for the treatment of septic forearm non-union. METHODS Septic non-unions are rare complications of forearm fractures. When they occur, they modify the relationship between forearm bones leading to a severe functional impairment. Treatment is challenging and surgery and antibiotic therapy are required to achieve infection resolution. It is even harder to obtain non-union healing with good functional results. The aim of this study is to present a two stages surgical treatment for septic forearm non-union with revision and temporary stabilization of the non-union until infection has cleared and subsequently perform a new synthesis with plate, opposite bone graft strut and intercalary graft. We retrospectively reviewed 18 patients with a mean age at the time of primary injury of 34.5 years (19-57 years) and a mean follow-up of 6 years (2-10 years). All patients presented an atrophic non-union with a mean length of the bone defect of 1.8 cm (1.2-4 cm). Complications and clinical results after surgical treatment were recorded. RESULTS Mean time to resolution of the infectious process was 8.2 wk (range 4-20 wk) after the first surgery and specific antibiotic therapy. All the non-union healed with an average time of 5 mo (range 2-10 mo) after the second step surgery. Cultures on intraoperative samples were positive in all cases. No major intraoperative complications occurred. Two patients developed minor complications and one needed a second surgical debridement for infection resolution. At the last follow-up functional results were excellent in 5 (27.8%) patients, satisfactory in 10 (55.5%) and unsatisfactory in 3 (16.7%) patients. No activities of daily living (ADLs) limitations were reported by 12 (66.6%) patients, slight by 3 (16.6%) and severe limitation by 3 (16.6%) patients. Mean visual analog scale at the last follow-up was 1 (0-3). CONCLUSION The two-step technique has proven to be effective to achieve resolution of the infectious process and union with good functional results and low rate of complications.

Prenatal Diagnosis of Clubfoot: A Review of Current Available Methodology

Abstract Background: Clubfoot is one of the most common congenital limb deformities. Prenatal diagnosis of the condition is essential as it can help treat the malformation as early as possible. We reviewed the recent available literature concerning the current methods for prenatal diagnosis of clubfoot. Methods: The following databases were searched from 1966 to 2015: PubMed, OVID, Cochrane, CINAHL, Google scholar and Embase. Results: Out of a total number of 197 retrieved articles, after abstract or title page evaluation, 158 articles not matching the inclusion criteria were excluded. The full text versions of the remaining 39 articles were obtained, and their reference lists screened, with the addition of another 5 full-text articles. Conclusions: Currently, ultrasonography is considered the most reliable method of prenatal diagnosis of clubfoot. Ultrasonographic diagnosis of clubfoot appears more likely between the 18th and the 24th week of pregnancy. Alternative imaging is not indicated. There is no agreement whether to propose foetal karyotyping when isolated clubfoot is diagnosed by prenatal ultrasonography. Early detection of clubfoot should prompt a careful surveillance during pregnancy in order to detect any possible additional abnormalities and, if any of these are detected, invasive testing should be offered.
