Diminished coordination skills may predispose injury to lesser toe fractures-a pilot study.

INTRODUCTION: Lesser toe fractures of the foot are a common lower extremity injury. The common mechanism of injury is a direct impact of force on the toe due to a collision of the toe with an object, often related as accidental injury or clumsiness. MATERIALS AND METHODS: This is a case-control study. We compared patients with lesser toe fractures to a healthy control group. We used a motor imagery tool to evaluate the proprioception and function of the pre-motor, center of motion planning cortex. Forty images of the left/right feet in various positions were incorporated into a dedicated software application. Participant reaction time and accuracy of recognition were recorded. RESULTS: Forty-two adult participants (20 with lesser toe fractures and 22 in the control healthy group) were included in the study. There was no difference in the participant's self-perception of clumsiness or involvement in activities that are related to better coordination. There was no difference in the accuracy or the reaction time in the motor imagery tool. The control group was significantly (p < 0.05) more accurate in recognizing their dominant side, whereas the fracture group was more accurate in recognizing their non-dominant side. CONCLUSIONS: Our findings do not support the premise that diminished coordination skills may predispose to injury to lesser toe fractures. Our findings may suggest that mixed laterality (hand/foot) is related to lesser toe fractures and thus may be related to clumsiness. Whether these alterations in perception bare merit in other types of physical injuries has yet to be explored.

Treating Hallux Valgus Associated Metatarsus Adductus by Minimally Invasive Surgery: A Simple Solution for a Difficult Problem.

This study aims to assess a novel minimally invasive surgical technique that addresses hallux valgus accompanied by metatarsus adductus. We retrospectively analysed the results of 20 patients (21 feet) that underwent a newly developed percutaneous osteotomy procedure of the lesser metatarsal bones in order to correct hallux valgus deformities accompanied by metatarsus adductus. We used x-ray studies in order to evaluate changes in the hallux valgus angle, the first intermetatarsal angle, and the metatarsal angle (using the modified Sgarlato method). We also compared the pre- and postoperative American Orthopaedic Foot and Ankle Society scores when available. The paired sample t test was used to compare variables. At a 1-y follow-up the mean hallux valgus angle, inter-metatarsal angle and the metatarsal angle have been reduced by 31.62 (-3 to 9), 3.86 (11-52) and 14.69 (4-36) respectively (p < .001 for all). The mean American Orthopaedic Foot and Ankle Society score (n = 15 feet available) has been improved by a mean of 44.53 (22-72, p < .001). In addition, the patient satisfaction rates were high. Patients suffered from mild to moderate midfoot pain during the first few weeks following surgery, which resolved when union occurred. No cases of lesser metatarsal nonunion have been documented. The presented minimally invasive method can be used effectively to correct hallux valgus that is associated with metatarsus adductus. Proximal minimally invasive metatarsal osteotomy can effectively correct hallux valgus accompanied by metatarsus adductus.

Lateral Column Lengthening for Flexible Flat Foot: Was It Short to Begin With?

BACKGROUND: Flexible flatfoot (FF) is a common foot deformity that can often consist of foot pain. Surgical treatment is designed to lengthen the lateral column. OBJECTIVES: To resolve whether radiographic standing feet measurements of normo-plantigrade feet and FF, symptomatic or not, differ and to determine whether the lateral column is shorter. METHODS: The study comprised 72 patients (127 feet) consecutive patients, 18 years of age and older, who were divided into three groups: normal feet (56), asymptomatic FF (29), and symptomatic FF (42). All patients had a standing anterior posterior (AP) and lateral radiographs. AP images were used for the measurement of the talocalcaneal angle, talar-1st metatarsal angle, and talonavicular coverage. Lateral X-rays were used to estimate the talocalcaneal angle, talar-1st metatarsal angle, calcaneal pitch, naviculocuboid overlap, and column ratio. RESULTS: All three of the AP radiograph measurements differed among groups, and higher values were measured in the symptomatic FF group. Post hoc analysis found that the talonavicular coverage and the talocalcaneal angles also differed between symptomatic and asymptomatic FF patients. While some lateral measurements differed within groups, only the lateral talar-1st metatarsal angle distinguished between asymptomatic and symptomatic patients. The lateral column length was not found to be shorter among FF patients, weather symptomatic or not. CONCLUSIONS: Only the talonavicular coverage, the AP talocalcaneal, and the lateral talar-1st metatarsal angles were found to differ between asymptomatic and symptomatic FF patients. The lateral column was not found to be shorter.

Locking versus standard screw fixation for acetabular cups: is there a difference?

INTRODUCTION: Total hip replacement has been established as a valid treatment option for displaced subcapital fractures. However, insufficient primary fixation may be the reason for early loosening in these osteoporotic patients. Primary fixation of the cup is usually achieved by press-fit fixation that can be enhanced using screws. Locking the screws into their respective cups may seem to improve the primary fixation of the construct, as locked plates proved superior fixation for osteoporotic fractures. METHODS: The study consisted of three groups: in each group, three cups were fixed into blocks of foam bone using press-fit technique. In the first group, no additional screws were used, in the second group two standard screws were inserted, while in the third group two acetabular screws were cemented into the cup to simulate locked screw fixation. Load was applied onto the rim of the acetabular component to cause shearing between the cup and the block. Cup fixation was examined by a loading machine that acquired load versus displacement. The stiffness (load vs. displacement) was calculated. RESULTS: Screws, either locked or non-locked, enhanced cup fixation by 26 % (p value <0.01). No significant changes were found between the locking and non-locking screws groups. DISCUSSION: These experimental results indicate that acetabular screws enhance primary cup fixation. This may become significant in conditions where the acetabular bone stock is suboptimal, such as when performing total hip arthroplasty after displaced subcapital fractures. However, there is no superiority for locked screws over standard screw fixation.

Do weight-bearing films affect decision making in hallux valgus surgery?

Hallux valgus is a complex deformity of the first ray and forefoot that can be surgically treated using different procedures and osteotomies. Preoperative planning includes anteroposterior and lateral plain films. The effect of weight-bearing on the results of the standardized measurements is still the subject of debate. We evaluated the effect of weight-bearing on the results of measurements and decision making by expert evaluators. A total of 21 foot and ankle surgeons were given weight-bearing and non-weight-bearing anteroposterior plain foot films of patients with hallux valgus. They were asked to measure 3 standard angles and then to select the most appropriate procedure from a short list. Using a paired Student's t test, no difference in the angles measured nor in the procedures chosen was detected between the weight-bearing and non-weight-bearing films. Although it is generally accepted that decisions regarding the treatment of hallux valgus should be based on plain weight-bearing films, in the present study, we established that non-weight-bearing films can reliably be used to choose the surgical procedure.

Ankle tourniquet pain control in forefoot surgery: a randomized study.

BACKGROUND: Forefoot surgery is often performed under regional anesthesia in awake patients, using tourniquet or Esmarch bandage to obtain a bloodless field. The purpose of this study was to examine the value and need for local tourniquet pain control using local subcutaneous analgesic mixture in patients undergoing forefoot surgery under ankle block anesthesia. MATERIALS AND METHODS: We prospectively randomized 56 patients who underwent forefoot surgery under ankle block to receive either subcutaneous local anesthetic mixture under the tourniquet or no additional anesthetic. We checked for local tourniquet pain score (VAS 0 to 100) and skin condition during and after the procedure. RESULTS: The tourniquet was quite tolerable in both groups, with an average VAS score of 7 to 21. No difference was observed between groups throughout most of the procedure. No correlation between VAS scores and procedure length or patient's age or gender was found. CONCLUSION: An ankle tourniquet was well-tolerated by patients without need for local anesthetic beneath the cuff.

Fractures of the distal humerus in elderly patients treated with a ring fixator.

The aim of distal humerus fracture treatment is articular surface reduction and stable fixation for early mobilisation and rehabilitation. This is usually performed by open reduction and internal fixation with plates. In the elderly osteoporotic patient this treatment is difficult to achieve due to fixation failure in fragile bone. We present our experience with treatment by closed reduction and external fixation with a non-bridging ring fixator in distal humerus fractures in elderly patients. There were ten females, aged 70-89 (average 78.4). Fracture types (AO/ASIF) included three supracondylar fractures (type A) and seven intercondylar fractures (type C). All patients were treated by closed reduction and external fixation with a non-bridging ring fixator of the distal humerus and immediate postoperative mobilisation of the elbow. External fixation was removed on an average of 72 days (range 62-90). All fractures united. Average time to union was 56 days. Average range of movement at six months was 22° extension lag (range 15°-30°) and 115° flexion (range 110°-120°). Complications included one patient with transient radial palsy and one patient with a superficial decubitus ulcer on the chest wall from the hardware. Minimally invasive treatment by closed reduction and external fixation with a ring fixator is effective for treatment of fractures of the distal humerus in elderly patients with osteoporotic bone. This treatment enables immediate mobilisation of the elbow, and allows return to function. It should be considered an alternative to open reduction and internal fixation or total elbow replacement.

Multidisciplinary team led by internists improves diabetic foot ulceration outcomes a before-after retrospective study.

STUDY OBJECTIVE: Diabetic foot ulceration (DFU) is associated with high mortality and morbidity. A multidisciplinary approach has been suggested, but as these patients usually present with various comorbidities, leadership of a multidisciplinary team by internists was initiated. Our aim was to evaluate the impact of the leadership of the multidisciplinary team by internists on the outcomes of patients with DFU. METHODS: Outcomes of patients with salvable DFU admitted pre and post introduction of the multidisciplinary team were compared, i.e., a major amputation (above or below the knee), blood stream infection, major medical complications, 30 day mortality, vascular interventions, diabetes control, medication regiments and laboratory results. RESULTS: The cohort included 315 patients, 207 - multidisciplinary pre-period and 108 - multidisciplinary period. During the multidisciplinary period, the rates of major amputations, blood stream infections were found significantly lower than the pre-multidisciplinary period (10% vs. 14%; p = 0.01 and 2% vs. 13%, p = 0.04, respectively). The 30 day mortality rates tended to be lower (5% vs. 11%, p = 0.08). Vascular interventions increased significantly (18% vs. 1%, p<0.01). The diabetes control significantly improved (median glucose levels 163 vs. 185 mg/dl, p = 0.03). Treatment consisting of angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers, statins) were updated and laboratory results at discharge (albumin, CRP) showed improved disease control. CONCLUSION: The treatment of hospitalized DFU patients by a multidisciplinary team led by internists using a holistic therapeutic approach demonstrated improved clinical outcomes.

Correction of Severe Hallux Valgus with Metatarsal Adductus Applying the Concepts of Minimally Invasive Surgery.

The combination of hallux valgus and metatarsus adductus presents a surgical challenge even for the experienced foot and ankle surgeon, as the position of the lesser metatarsals restricts the space for metatarsal head displacement. We describe the application of concepts of minimally invasive techniques to correct this deformity. Proximal metatarsal osteotomy to correct the position of lesser metatarsals, followed by minimally invasive bunion surgery, shows promising results. In a short series, proximal metatarsal osteotomy showed excellent correction of the deformity. At final follow-up, all the deformed feet consolidated in correct positions.

Treating civilian gunshot wounds to the extremities in a level 1 trauma center: our experience and recommendations.

BACKGROUND: Gunshot wounds impose a continuous burden on community and hospital resources. Gunshot injuries to the extremities might involve complex soft tissue, bone, vascular, musculotendinous, and nerve injuries. A precise knowledge of anatomy is needed to evaluate and treat those injuries. OBJECTIVES: To review our experience with gunshot wounds to the extremities. METHODS: We retrospectively reviewed all civilian cases of gunshot wounds to the limbs treated in our institution during 2003-2005. Altogether, we evaluated 60 patients with 77 injuries. RESULTS: Of the 60 patients 36 had fractures, 75% of them in the lower extremity and 81% in long bones. The most common fixation modality used was external fixation (33%), followed by intramedullary nailing (25%). This relatively high percentage of fracture treated with external fixation may be attributed to the comminuted pattern of the fractures, the general status of the patient, or the local soft tissue problems encountered in gunshot wounds. About one-fifth of the fractures were treated by debridement only without hardware fixation. We treated 10 vascular injuries in 8 patients; 6 of them were injuries to the popliteal vessels. Fractures around the knee comprised the highest risk factor for vascular injuries, since 5 of the 12 fractures around the knee were associated with vascular injury requiring repair or reconstruction. There were 13 nerve injuries (16.8%), most of them of the deep peroneal nerve (38%). Only three patients had concomitant nerve and vascular injuries. The overall direct complication rate in our series was 20%. CONCLUSIONS: To successfully treat complex gunshot injuries a team approach is necessary. This team should be led by an orthopedic surgeon knowledgeable in the functional anatomy of the limbs.

Outcome of non-surgical treatment of proximal femur fractures in the fragile elderly population.

INTRODUCTION: With the aging of the population the rate of fragility hip fractures increases. While medical recommendations are for hasten surgical treatment, for some older patients burdened with severe comorbidities, this might be risky. AIMS: To compare the outcomes of patients treated non-surgically to those of the most fragile patients treated surgically. PATIENTS AND METHODS: A retrospective cohort study, of individuals aged ≥65 years who presented with fragility hip fractures between 01.01.2011-30.06.2016, to a primary trauma center. Patients treated surgically were stratified according to their age-adjusted Charlsons' comorbidity index (ACCI) score. Patients in the upper third of ACCI score, representing the more fragile population, were compared to patients treated non-surgically. RESULTS: 847 patients presented with fragility fractures. 94 (11%) were treated non-surgically and 753 (89%) underwent surgery. Medical reasons were the leading cause for non-surgical treatment (61.7%). Surgically-treated patients were stratified according to their ACCI and 114 patients with ACCI > 9 were chosen for comparison. While both groups were comparable in terms of age, the non-surgical treatment group had more female patients (p. = 0.026) and a smaller proportion of independent walkers (p < 0.001). The ACCI was higher for the surgical treatment group (p < 0.001). In-hospital mortality was similar (14.9% and 18.1% for the operative and non-surgical groups respectively, P. = 0.575). However, one-year mortality was significantly higher for the non-surgical group (48.2% vs. 67.0%, P. = 0.005). The rates of in-hospital complications and 1-year readmissions were similar. CONCLUSIONS: Operative treatment for fragility hip fracture reduces long-term mortality rates even in the more fragile patients, compared to non-surgical treatment.

Medial forefoot fillet flap for primary closure of transmetatarsal amputation: A series of four cases.

Amputation of the forefoot is a salvage procedure for several forefoot acute or chronic infection. A good, sensate and durable skin cover is important for quicker and better rehabilitation. The use of filleted flaps (or "spare parts technique") has been published in the past as a creative technique. The purpose of this article is to introduce a reproducible, pre-planned, technique that requires less creativity for the use of the "spare parts". The authors describe a case series of 4 patients with deep infection and osteomyelitis of the forefoot, without involvement of the medial skin that underwent two staged procedure for transmetatarsal amputation with medial forefoot fillet flap. The first procedure was amputation of the 4 lesser metatarsal and the wound was left open. After a few days the second operation was done with amputation of the first metatarsal bone and using the filleted medial skin and subcutaneous tissue for closure of the wound. In conclusion the medial fillet flap is an effective method of covering large wounds after partial, lateral forefoot amputation. This method shortens the healing time of the patient, and in hospital stay. The authors recommend using the staged method when dealing with diabetic patients with partial, central and lateral forefoot deep infection and/or necrosis.

Chondrolysis of the Hip following Septic Arthritis: A Rare Complication of Magnetic Resonance Arthrography.

Magnetic resonance arthrography (MRA) is commonly used to detect labral tears of the hip. Complications of MRA are unusual and include minor reactions such as chemical synovitis and urticaria. This paper presents a rapidly progressive chondrolysis of the hip in a young patient after arthrography. The patient had suffered from acute septic arthritis and was treated by emergent arthroscopic surgery followed by appropriate antibiotics. At 18 months of followup, there were no signs of active infection but evidence of joint chondrolysis. Magnetic resonance arthrography (MRA) of the hip is an invasive procedure and should therefore be recommended judiciously. Post-MRA pain is common but often mild and temporary, while post-MRA joint infection is rare; nevertheless, severe joint pain and limitation should raise suspicion for septic hip.

Gender differences among patients with proximal femur fractures during rehabilitation.

BACKGROUND: Proximal femoral fractures (PFFs) frequently occur in the elderly population and increase with age. Previous studies reported gender differences in previous functional level and co-morbidity among PFF patients. However, data relating to the relationship between gender differences of PFF patients and their rehabilitation outcome is ambiguous. OBJECTIVE: The aims of the present study were to describe PFF patients within a rehabilitation setting and to examine if there were gender differences between patients. METHODS: This was a cohort study of 823 PFF patients (649 women and 174 men; average age, 82.36 [7.62] years) admitted consecutively to the Department of Geriatric Orthopaedic Rehabilitation in a post-acute geriatric rehabilitation center between January 1, 2006 and December 31, 2009. The collected data included demographic variables: variables related to fracture, including fracture type and side, treatment type, time from fracture to operation, and weight bearing instruction; clinical variables, including co-morbidities and albumin and hemoglobin levels; and functional variables, such as patients' pre-fracture functional status and functional level on admission using the Functional Independence Measure, the Mini Mental State Examination, and mood state measured by the Geriatric Depression Screening Scale. RESULTS: More subcapital fractures were found among the men, and more pertrochanteric fractures were found among the women. More men were educated, lived at home with a caregiver, were functionally independent before the fracture event, and had more co-morbidities than women. No significant differences in the functional outcome measures score were found between the 2 genders. Significantly more men died during rehabilitation. CONCLUSIONS: The lack of differences in functional gain between the genders during rehabilitation might be explained by the similarity in admission functional and cognitive levels between the genders, which were found to be the most important factors affecting rehabilitation outcome.

Trends in femoroacetabular impingement research over 11 years.

Femoroacetabular impingement is the abutment between the proximal femur and the rim of the acetabulum. It is a common cause of labral injury that has been identified as an early cause of hip osteoarthritis. The diagnosis of femoroacetabular impingement of the hip is currently well defined in orthopedic surgery but should attract the attention of physicians in other disciplines. Conversely, much less is known about the etiology and natural history of femoroacetabular impingement.The goal of this study was to assess the number of articles published on femoroacetabular impingement over 11 years in orthopedic vs nonorthopedic medical journals, and to evaluate the quality of available evidence. PubMed and OvidSP databases were searched for articles on femoroacetabular impingement published from 1999 to 2009. Articles were characterized by publication type and journal type per year. Regression analysis was used to determine the effect of publication year on number of publications of each type. The search yielded 206 publications on femoroacetabular impingement during the evaluation period. Seventy-two percent were published in orthopedic journals. Overall, the number of publications increased exponentially with time. There was an increase in clinical trials over the course of the study period. However, studies with high-quality evidence were scarce. The increase in data from orthopedic and nonorthopedic disciplines is welcome. Nevertheless, high-quality evidence on femoroacetabular impingement is lacking. We believe the current trend toward evidence-based orthopedic surgery will impact future research on this relatively new disorder.
