A modified minimally invasive osteotomy for hallux valgus enables reduction of malpositioned sesamoid bones.

BACKGROUND: The current minimally invasive distal metatarsal osteotomy for hallux valgus (HV) is V-shaped, which prevents the correction of the rotational metatarsal head deformity and reduction of the sesamoid bones. We sought to determine the optimal method for sesamoid bone reduction during HV surgery. METHODS: We reviewed the medical records of 53 patients who underwent HV surgery between 2017 and 2019 using one of three techniques: open chevron osteotomy (n = 19), minimally invasive V-shaped osteotomy (n = 18), and a modified straight minimally invasive osteotomy (n = 16). The sesamoid position was graded using the Hardy and Clapham method on weight-bearing radiographs. RESULTS: When compared to open chevron and V-shaped osteotomies, the modified osteotomy resulted in significantly lower postoperative sesamoid position scores (3.74 ± 1.48, 4.61 ± 1.09, and 1.44 ± 0.81, respectively, P < 0.001). Furthermore, the mean change in postoperative sesamoid position score was greater (P < 0.001). CONCLUSION: The modified minimally invasive osteotomy was superior to the other two techniques in correcting HV deformity in all planes, including sesamoid reduction.

The effect of postoperative weight-bearing status on mortality rate following proximal femoral fractures surgery.

INTRODUCTION: Proximal femur fractures are associated with an increased mortality rate in the elderly. Early weight-bearing presents as a modifiable factor that may reduce negative postoperative outcomes and complications. As such, we aimed to compare non-weight-bearing, partial-weight-bearing and full weight-bearing cohorts, in terms of risk factors and postoperative outcomes and complications. METHODS: We retrospectively reviewed our database to identify the three cohorts based on the postoperative weight-bearing status the day of surgery from 2003 to 20014. We collected data on numerous risk factors, including age, cerebrovascular accident (CVA), pulmonary embolism (PE), surgical fixation method and diagnosis type. We also collected data on postoperative outcomes, including the number of days of hospitalization, pain levels, and mortality rate. We performed a univariate and multivariate analysis; P < 0.05 was the significant threshold. RESULTS: There were 186 patients in the non-weight-bearing group, 127 patients in the partial-weight-bearing group and 1791 patients in the full weight-bearing group. We found a significant difference in the type of diagnosis between cohorts (P < 0.001 in univariate, P < 0.001 in multivariate), but not in fixation type (P < 0.001 in univariate, but P = 0.76 in multivariate). The full weight-bearing group was diagnosed most with pertrochanteric fracture, 48.0%, and used Richard's nailing predominantly. Finally, we found that age was not a significant determinant of mortality rate but only weight-bearing cohort (P = 0.13 vs. P < 0.001, respectively). CONCLUSION: We recommend early weight-bearing, which may act to decrease the mortality rate compared to non-weight-bearing and partial weight-bearing. In addition, appropriate expectations and standardizations should be set since age and type of diagnosis act as significant predictors of weight-bearing status.

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.

Accuracy measures of 1.5-tesla MRI for the diagnosis of ACL, meniscus and articular knee cartilage damage and characteristics of false negative lesions: a level III prognostic study.

BACKGROUND: MRI is the most accurate imaging modality for diagnosing knee pathologies. However, there is uncertainty concerning factors predicting false negative MRI, such as meniscal tear patterns as well as patient factors. The aims of this study were to report 1.5-Tesla MRI accuracy of ACL, meniscus and articular cartilage damage and characterize false negative lesions. METHODS: Two hundred eighteen consecutive knee arthroscopies performed in our institution between 2013 and 2016 and their respective prospectively-collected MRI reports were reviewed. Inclusion criteria were age > 15 years-old, primary arthroscopy, 1.5-Tesla MRI performed at the same institution, and time interval MRI-surgery < 6 months. Exclusion criteria were revision arthroscopy and arthroscopic-assisted fracture fixation or multiligament surgery. Accuracy measures and Kappa coefficients were calculated comparing the MRI diagnosis to the arthroscopic findings. Moreover, the arthroscopic findings of false negative MRI were compared to the findings of true positive MRI using the Fisher-exact test. Pearson correlation was used for testing the correlation between MRI accuracy and patient age. RESULTS: The highest accuracy was observed in medial meniscus and in ACL findings. For the medial meniscus sensitivity, specificity, agreement, and Kappa coefficient were 77, 92, 86%, and 0.7, and for the ACL these measures were 82, 97, 87%, and 0.73. MRI accuracy was lower in the lateral meniscus and articular cartilage with Kappa coefficient 0.42 and 0.3, respectively. More specifically, short peripheral tears in the posterior horn of the medial meniscus were characteristic of false negative findings compared to true positive findings of the MRI (p <  0.01). MRI accuracy correlated negatively compared to arthroscopic findings with patient age for the medial meniscus (r = - 0.21, p = 0.002) and for articular cartilage damage (r = - 0.45, p <  0.001). CONCLUSION: 1.5-Tesla MRI will accurately diagnose ACL and medial meniscal tears and can reliably complete the diagnostic workup following physical examination, particularly in young adults. This modality however is not reliable for diagnosing short peripheral tears at the posterior horn of the medial meniscus and partial thickness articular cartilage lesion of the femoral condyles. For these lesions, definitive diagnosis may require cartilage-specific MRI sequences or direct arthroscopic evaluation. LEVEL OF EVIDENCE: Prognostic study, Level III.

VIRTUAL ORTHOPEDIC-REHABILITATION-METABOLIC COLLABORATION FOR TREATING OSTEOPOROTIC HIP FRACTURES.

Objective: To evaluate the effectiveness of a virtual, closed-loop protocol that treated hip fracture patients without formal clinic visits. Methods: In this prospective cohort study, an intervention group of 85 hip fracture patients (33.6%) with vitamin D levels ≥65 nmol/L who received recommendations for osteoporosis treatment, was compared to a nonintervention group of 168 (66.4%), with vitamin D <65 nmol/L. Treatment included vitamin D loading in orthopedic and rehabilitation departments for patients from both groups, and virtual, osteoporosis treatment recommendations by Metabolic Clinic physicians to patients from the intervention group upon achieving a vitamin D level ≥65 nmol/L. Recommendations were given without requiring clinic visits. Osteoporosis drug recommendations were relayed to primary care physicians. The primary endpoint was patients receiving osteoporosis drugs within 12-months post-surgery. Secondary endpoints were patients issued drugs within 3- and 6-months post-surgery, and 1-year post-fracture mortality rates. Results: Among 253 hip fracture patients (81.3 ± 10.7 years-of-age, 68.8% women), the postintervention osteoporosis medication issue rate was higher than in the nonintervention group (48.2% versus 22.0%, respectively; P<.001). More intervention group patients received drugs 3 months (18.8% versus 2.9%; P<.001) and 6 months after surgery (40% versus 5.9%; P<.001). One-year mortality was lower among patients who received any osteoporosis medications (either through our intervention or from community physicians) than among untreated patients (5.1% versus 26.3%; P<.001). Conclusion: Virtual orthopedic-rehabilitation-metabolic collaboration increased osteoporosis treatment rates post-hip fracture. Yet, treatment rates remained <50%. Additional research is required to increase treatment rates further, such as providing drug therapy shortly after surgery, perhaps during rehabilitation, or lowering the vita-min D threshold.

Does the IOFix implant improve union rates?

BACKGROUND: First metatarso-phalangeal joint fusion is the current gold standard for severe hallux rigidus. Data regarding the union rate and the re-operation rate when IOFix (an Intra-osseous fixation device, Extremity medical, New Jersey, USA) is used for hallux rigidus fusion is limited but promising. The aim of this study was to review our outcomes with the IOFix implant. METHODS: We have conducted a retrospective chart review, following the approval of the hospital IRB committee. Exclusion criteria included bilateral operations on the same patient, multiple surgeries, charcot foot or other structural foot abnormalities (except hallux valgus), rheumatoid arthritis and a recent foot trauma. We collected demographic data, physical examination documentation, functional score evaluations (AOFAS), and Plain radiographic studies. RESULTS: Thirty patients were included in the study. The mean age was 60.36 ± 9.12 (range 36 to 77) years, 18 (60%) female patients and 12 (40%) male. Fourteen (53.33%) were left side pathologies. The average follow up period was 36.2 ± 12.31 (range 12 to 54) months. Union was obtained in 28 (93.33%) patients, of whom none had requested a hardware removal due to a prominent hardware during a minimum of 2 year follow up period. The mean postoperative AOFAS score was 80.5 ± 10.87 (range 35 to 90). A more stringent inclusion criteria and fusion definitions would have led to an exclusion of two more patients and a dropout of two patients from the "fused" group, which would have led to a fusion rate of 85.71%. CONCLUSIONS: This is the largest series of hallux rigidus patients that were operated with an IOFix device. The rates of fusion and hardware removal in MTPJ1 arthrodesis performed with an IOFix implant were found to be similar at most when compared to previously described rates that were obtained with other cheaper and more simple fixation devices.

Combined reconstruction of the medial patellofemoral and medial patellotibial ligaments: outcomes and prognostic factors.

PURPOSE: To report outcomes after combined medial patellofemoral ligament (MPFL) and medial patellotibial ligament (MPTL) reconstruction and test associations between prognostic factors and clinical outcomes. It was hypothesised that combined MPFL and MPTL reconstruction would result in significant improvement in function, and that outcomes would be associated with age, sex, Beighton score, concomitant articular lesions, and preoperative function. METHODS: All combined reconstructions of MPFL and MPTL were reviewed. Inclusion criterion was minimum 2-year follow-up. Exclusion criteria were age at surgery ≥ 35 years and concomitant osteotomies. Kujala, Tegner and Marx scores were completed prospectively. Patients were evaluated at a minimum 2-year follow-up. Associations between potential prognostic factors and Kujala and Tegner scores were tested using bivariate analyses followed by multivariate regression models. RESULTS: Of 22 patients (26 knees), 19 (23 knees) met inclusion criteria, and 16 (20 knees) were available for follow-up. Mean age at surgery was 18 years (range 14.5-23). Mean follow-up was 43 months (range 24-73). Postoperative Kujala score significantly improved compared to before surgery (86.4 ± 12.5 vs. 54.9 ± 15.2, p < 0.01). Postoperative Tegner score was nonsignificantly higher compared to before surgery (4.8 ± 2.4 vs. 4 ± 3, p = ns) and lower compared to before first patella dislocation (4.8 ± 2.4 vs. 5.9 ± 1.2, p < 0.01). Postoperative Kujala score was associated with male sex (p = 0.02), with medial patellofemoral chondral lesions (p = 0.01) and with preoperative Kujala score (p = 0.05). Postoperative Tegner score was associated with male sex (p < 0.01), with preoperative Tegner level (p < 0.01), and with Beighton score (p < 0.01). Patella apprehension was recorded in two knees (10%) in two patients. CONCLUSION: Combined MPFL and MPTL reconstruction in young adults results in significant improvement in subjective knee function with minimal risks, although preinjury activity levels are not consistently restored. Associated factors of improved outcome include higher preoperative knee scores and activity levels, medial patellofemoral chondral lesions, decreased Beighton scores, and male sex. This supports the advisability of the procedure and can also assist in setting realistic goals for specific groups of patients. LEVEL OF EVIDENCE: Case series, Level IV.

Orthopedic-Metabolic Collaborative Management for Osteoporotic Hip Fracture.

OBJECTIVE: Osteoporotic hip fractures are associated with increased morbidity, mortality, and secondary fractures. Although osteoporosis treatment can reduce future fracture risk, patients often do not receive it. We report results of a coordinator-less fracture liaison service in Israel addressing hip fracture patients. The primary endpoint was attending the Metabolic Clinic. Secondary endpoints included vitamin D measurement, calcium and vitamin D recommendations, initiation of osteoporosis treatment, and mortality 1-year post-fracture. METHODS: This prospective study included 219 hip fracture patients who were compared with historical controls. Data on hospitalized patients were collected before and after implementation of a structured protocol for hip fracture patients, led by a multidisciplinary team, without a coordinator. RESULTS: The study included 219 and 218 patients ≥60 years old who were operated on in 2013 and 2012, respectively. Metabolic Clinic visits increased from 6.4 to 40.2% after the intervention ( P<.001). Among 14 patients who attended the Clinic in 2012, 85.7% began osteoporosis therapy; among 88 who attended in 2013, 45.5% were treated at the first visit. Vitamin D measurements and calcium and vitamin D supplementation increased postintervention (0.5-80.1%, P<.001; 30.8-84.7%, P<.001, respectively). Patients receiving osteoporosis medications had lower mortality rates than untreated patients (4.3% vs. 21.8%). CONCLUSION: An Orthopedic-Metabolic team implemented by existing staff without a coordinator can improve osteoporosis care for hip fracture patients. Yet, gaps remain as only 40% had Metabolic Clinic follow-up postintervention, and of these, only half received specific treatment recommendations. Hospitals are encouraged to adopt secondary fracture prevention protocols and continuously improve them to close the gaps between current management and appropriate metabolic assessment and treatment.

The correlation of supraspinatus outlet view with computed tomography for visualization of the anterior acromial undersurface.

INTRODUCTION: Understanding the real shape of the undersurface of the acromion prior to acromioplasty is indispensable. Today, Supraspinatus outlet view (SSOV) is a standard view used to determine the shape of the anterior acromion. Three types of acromial undersurface were described by Bigliani and Morrison. The purpose of this study was to find out whether the real acromial type can be visualized on X-ray SSOV and compare the shape of the anterior undersurface of the acromion visualized on SSOV, with the shape revealed on 2D CT reconstructions. METHODS: The SSOV X-rays and CT scans of 30 consecutive patients suffering from rotator cuff dysfunction were retrospectively analyzed. The shape of the acromion visualized on plain X-rays was classified according to Bigliani and Morrison classification system. Two-dimensional CT reconstructions were performed, reproducing the lateral, middle, and medial sections of the acromion. The acromial type that was visualized on each of those reconstructions was separately classified according to the Bigliani and Morrison system. A complete profile of the acromial undersurface was constructed from the integration of acromial types seen on each CT section. The acromial morphology seen on X-rays and CTs was compared. RESULTS: A total of 30 patients comprised the study cohort; mean age was 57 (STD = 8.5) years. Three Type I, 22 Type II, and 5 Type III acromions were visualized on the SSOV X-rays. CT reconstructions revealed seven different morphological acromial profiles (I,I,I; I,II,II; I,II,III, etc.), which we divided into 3 groups: (1) Uniform (30%), (2) Internally curved (20%), and (3) Internally hooked (50%). The acromial type visualized on X-ray correlated with the acromial type on at least one CT section in all of the cases. In the case of uniform acromial profile, there is a full correlation between the acromial type visualized on X-rays and the type visualized on CT. In non-uniform profiles, there was an incomplete correlation between the types of the acromion visualized on SSOV and CT. SSOV X-rays correlated with or underestimated, but never overestimated, the acromial morphological type. DISCUSSION: The curved or hooked portion of the acromial undersurface is not always visualized on the SSOV. On X-rays, the middle and lateral sections are seen more accurate than the medial section. CONCLUSION: Surgeons should be aware that SSOV X-rays may underestimate the true type of the acromial undersurface.

Injuries can be prevented in contact flag football!

PURPOSE: This original prospective cohort study was conducted in an attempt to significantly reduce the incidence and the severity of injuries in an intervention cohort as compared to a two-season historical cohort, and to provide recommendations to the International Federation of Football (IFAF) pertaining to prevention measures to make the game safer. METHODS: A total of 1,260 amateur male (mean age: 20.4 ± 3.9 years) and 244 female (mean age: 18.5 ± 1.7 years) players participated in the study. Four prevention measures were implemented: the no-pocket rule, self-fitting mouth guards, ankle braces (for those players with recurrent ankle sprains) and an injury treatment information brochure. All time-loss injuries sustained in game sessions were recorded by the off-the-field medical personnel and followed up by a more detailed phone injury surveillance questionnaire. RESULTS: There was a 54 % reduction in the total number of injuries and a significant reduction in the incidence rate and incidence proportion between the intervention cohorts as compared to the historical cohort (p < 0.001). There was no statistically significant reduction in the number of injuries in any of the body parts, except for in hand/wrist injuries related to the use of pockets (p < 0.001), as well as the severity of mild-moderate injuries (p < 0.05). CONCLUSION: This study provided evidence that hand/wrist injuries can be significantly reduced in flag football. Recommendations to the IFAF include strict enforcement of the no-pocket rule, the use of soft headgear, comfortable-fitting ankle braces and mouth guards and additionally, to change game rules concerning blocking.

Injuries in a Developing Sport, Cachibol (Newcomb Ball).

BACKGROUND: Cachibol (known as kadureshet in Hebrew) is a team ball game whose characteristics are similar to those of volleyball. The game is becoming increasingly popular, particularly among adult women and is the fastest growing female sport in Israel. Despite its growing popularity, data on the epidemiology of injuries incurred from this sport are sparse. OBJECTIVES: To investigate the incidence and severity of injuries among adult female cachibol players. METHODS: We conducted a cross-sectional survey and observational cohort study of 612 amateur female cachibol players participating in a 3 day national tournament; 355 players completed questionnaires relating to traumatic injuries incurred during previous cachibol activity (58% response rate). All injuries sustained during the tournament were reported. RESULTS: Fingers were the most commonly injured part of the body, mostly due to a direct hit by the ball. Finger injuries, though considered mild, may have long-term implications: over 50% of the injured players reported long-term finger discomfort. After finger injuries, ankles and knees were the second most commonly injured parts of the body, with a higher rate of absence from sports activity and work and for a longer time compared to finger injuries. CONCLUSIONS: Due to the unique characteristics of cachibol, the rate of finger injuries is higher than in volleyball. Injuries are a growing cause for concern in view of the rapidly increasing number of cachibol players. Our findings may be useful for developing effective injury prevention programs for cachibol players.

Value of Early Postoperative Computed Tomography Assessment in Ankle Fractures Defining Joint Congruity and Criticizing the Need for Early Revision Surgery.

Previous investigators have questioned the reliability of plain radiographs in assessing the accuracy of ankle fracture reduction when these were compared with the computed tomography (CT) evaluation in the preoperative setting, in particular, in fractures with syndesmosis injuries or trimalleolar fragments. The role of CT assessment, however, has not been investigated in the early postoperative setting. In the early postoperative setting, reduction still relies most commonly on fluoroscopy and plain radiographs alone. In the present study, we hypothesized that early postoperative CT assessment of ankle fractures with syndesmosic injuries and posterior malleolar fragments can add valuable information about the joint congruity compared with plain radiographs alone and that this information could affect the decisions regarding the need for early revision surgery. A total of 352 consecutive operated ankle fractures were reviewed. Of these, 68 (19%) underwent early postoperative CT assessment and were studied further to identify the causes that prompted revision surgery. Of the 68 cases, despite acceptable reduction found on the plain radiographs, 20 (29%) underwent early (within 1 week) revision surgery after studying the CT scans, which revealed malreduction of the syndesmosis, malreduction of the posterior lip fragment, and intra-articular fragments. We concluded that in ankle fractures involving disruptions of the syndesmosis or posterior malleolar fragments, early postoperative CT assessment could be justified, because it will reveal malreduction and prompt early revision intervention for a substantial proportion of these patients.

Lower Extremity Kinematic Profile of Gait of Patients After Ankle Fracture: A Case-Control Study.

The present study examined the differences in the lower extremity gait kinematic profile of patients recovering from ankle fracture compared with healthy controls. In addition, we inquired whether the profile would differ among fracture severity groups. A total of 48 patients participated in the present prospective, case-control study. The gait of 24 patients recovering from an ankle fracture injury and 24 healthy matched controls was examined using an inertial measurement unit sensor system. The following gait parameters were evaluated: knee range of motion (ROM) during the swing phase, maximum knee flexion angle during stance, thigh and calf ROM, and stride duration. Statistically significant differences were found between the ankle fracture group and the control group for all parameters. The patients with ankle fracture had a lower knee ROM during swing phase compared with the control group (mean ± standard deviation 43.0° ± 15.5° compared with 66.7° ± 5.1°, respectively; p < .001). The maximum knee flexion angle during stance was lower in the patients with ankle fracture than in the control group (mean ± standard deviation 10.5° ± 6.1° compared with 21.2° ± 4.5°, respectively; p < .001). Patients with ankle fracture also had lower gait cycle thigh and calf ROM angles (p < .001) and a longer stride duration (p < .001) compared with the control group. No statistically significant differences were found among the severity groups. These results suggest that the gait kinematic characteristics vary between healthy people and patients recovering from an ankle fracture injury during the short-term period after injury.

[A NOVEL GENDER-SPECIFIC VEST FOR FEMALE INFANTRY RECRUITS DOES NOT REDUCE THE INCIDENCE OF OVERUSE PAIN SYNDROMES: A PROSPECTIVE RANDOMIZED STUDY AMONG 240 RECRUITS].

INTRODUCTION: Overuse pain syndromes constitute a troublesome byproduct of military infantry training, particularly in female fighters. These injuries result in lost days of training, pain and discomfort and can affect fitness and fighting abilities. We hypothesized that a gender specific vest would reduce the incidence of overuse pain syndromes in a population of female recruits during basic training. OBJECTIVE: The purpose of this study was therefore to examine the effect of a novel gender-specific combat vest on the incidence of lower back pain (LBP), anterior knee pain syndrome (AKPS), and plantar heel foot pain (PHFP) among female recruits. MATERIAL AND METHODS: A prospective randomized study was conducted among 243 female border police infantry recruits who were followed over 4-months of basic training. In this group, 101 females were equipped with standard unisex special unit fighting vest (SUFV) and compared to 139 females who were equipped with a novel well-padded new fighting vest (NFV), specifically designed to fit the upper body morphology of females. This novel vest was supplied in three sizes, and equipped with adjustable straps. Information regarding the occurrence of overuse injuries was collected every two weeks. Medical records and clinic visits were evaluated. Attention was given to complaints of low back pain (LBP), anterior knee pain (AKP) and plantar heel foot pain (PHFP). RESULTS: Two hundred and forty recruits completed the study. Three recruits were lost to follow-up. Anterior knee pain was recorded in 65% of recruits in the SUFV group versus 62% in the NFV group (p = ns). Lower back pain was recorded in 86% of the SUFV group versus 82% in the NFV group (p = ns), and plantar heel foot pain was recorded in 73% of the SUFV group versus 69% in the NFV group (p = ns). DISCUSSION: Overuse pain injuries are more commonly reported among female fighters. These injuries result in lost days of training, pain and discomfort and can affect combat ability. Several researchers have found that changes in fighting equipment, such as size and weight, can affect the rates of these injuries. There is still a lack of information regarding changes related to gender-based fighting equipment and their effects. CONCLUSION: A gender-specific combat vest, designed to fit the upper female body, did not have any protective effect on the occurrence of overuse pain syndromes of the back, knee and foot in this study. It seems that in order to reduce the incidence of these injuries in female recruits, emphasis should be directed at other factors such as modifications in equipment weight, as well as modifications in the intensity of the training programs.

Plasma rich in growth factors (PRGF) as a treatment for high ankle sprain in elite athletes: a randomized control trial.

PURPOSE: Syndesmotic sprains are uncommon injuries that require prolonged recovery. The influence of ultrasound-guided injections of platelet-rich plasma (PRP) into the injured antero-inferior tibio-fibular ligaments (AITFL) in athletes on return to play (RTP) and dynamic stability was studied. METHODS: Sixteen elite athletes with AITFL tears were randomized to a treatment group receiving injections of PRP or to a control group. All patients followed an identical rehabilitation protocol and RTP criteria. Patients were prospectively evaluated for clinical ability to return to full activity and residual pain. Dynamic ultrasound examinations were performed at initial examination and at 6 weeks post-injury to demonstrate re-stabilization of the syndesmosis joint and correlation with subjective outcome. RESULTS: All patients presented with a tear to the AITFL with dynamic syndesmosis instability in dorsiflexion-external rotation, and larger neutral tibia-fibula distance on ultrasound. Early diagnosis and treatment lead to shorter RTP, with 40.8 (±8.9) and 59.6 (±12.0) days for the PRP and control groups, respectively (p = 0.006). Significantly less residual pain upon return to activity was found in the PRP group; five patients (62.5 %) in the control group returned to play with minor discomfort versus one patient in the treatment group (12.5 %). One patient in the control group had continuous pain and disability and subsequently underwent syndesmosis reconstruction. CONCLUSIONS: Athletes suffering from high ankle sprains benefit from ultrasound-guided PRP injections with a shorter RTP, re-stabilization of the syndesmosis joint and less long-term residual pain. LEVEL OF EVIDENCE: II.

Anatomic Reconstruction Technique for a Plantar Calcaneonavicular (Spring) Ligament Tear.

Acquired flatfoot deformity in adults is usually due to partial or complete tearing of the posterior tibial tendon, with secondary failure of other structures such as the plantar calcaneonavicular (spring) ligament (SL), which maintain the medial longitudinal arch. In flexible cases, the tibialis posterior can be replaced with the flexor digitorum longus. It is common practice to suture the SL directly in the case of a tear; however, if the tear is complete, suturing directly to the ligament alone will not be possible. Reconstruction of the ligament is needed; however, no validated methods are available to reconstruct this ligament. The operative technique of SL reconstruction described in this report as a part of acquired flatfoot deformity reconstruction consists of augmenting remnants of the spring from the navicularis to the sustentaculum tali and suspending it to the medial malleolus using 2-mm-wide, long-chain polyethylene suture tape. This technique results in the firm anatomic reconstruction of the SL, in addition to "classic" medial arch reconstruction. We recommend SL reconstruction for medial arch reconstruction when the SL is torn.

Use of a spinal cage for creating stable constructs in ankle and subtalar fusion.

In complicated foot surgery with reconstruction of the hindfoot, a gap will sometimes be present between the bones that must be filled and stabilized. Bone grafting with structural bone graft is 1 alternative; however, it can collapse and must be stabilized with screws or a nail. A locking intramedullary nail can be used but could lead to nonunion owing to distraction. Newer nails include a compression device but that can result in shortening. We developed a technique that includes distraction of the fusion area with a spinal cage and then compression of the construct by inserting a compression screw through the cage. We present our experience with this technique.We reviewed the data from 7 patients who had undergone surgery using this technique. The technique included distraction of the fusion area and insertion of a titanium cylindrical spinal cage filled with autologous cancellous bone graft. A cannulated compression screw was then inserted through the cage, creating compression of the fusion area against the cage and achieving stabilization of the fusion area. Postoperatively, a non-weightbearing cast was applied for 3 months, followed by a full weightbearing cast until radiographic fusion was apparent. Complete radiographic union was observed in all 7 patients within 6 to 12 months postoperatively. At the latest follow-up visit, the mean American Orthopaedic Foot and Ankle Society scale score was 54 ± 16 (range 30 to 71) points. The use of a cylindrical titanium cage with a local bone graft and stabilization by distraction and compression provided a stable construct, avoided shortening, and led to good fusion. In addition, donor site complications and unpredictable strength loss and lysis of bone allograft were avoided.

The prevention of injuries in contact flag football.

PURPOSE: American flag football is a non-tackle, contact sport with many moderate to severe contact-type injuries reported. A previous prospective injury surveillance study by the authors revealed a high incidence of injuries to the fingers, face, knee, shoulder and ankle. The objectives of the study were to conduct a pilot-prospective injury prevention study in an attempt to significantly reduce the incidence and the severity of injuries as compared to a historical cohort, as well as to provide recommendations for a future prospective injury prevention study. METHODS: A prospective injury prevention study was conducted involving 724 amateur male (mean age: 20.0 ± 3.1 years) and 114 female (mean age: 21.2 ± 7.2 years) players. Four prevention measures were implemented: the no-pocket rule, self-fitting mouth guards, ankle braces (for those players with recurrent ankle sprains) and an injury treatment information brochure. An injury surveillance questionnaire was administered to record all time-loss injuries sustained in game sessions. RESULTS: There was a statistically significant reduction in the number of injured players, the number of finger/hand injuries, the incidence rate and the incidence proportion between the two cohorts (p < 0.05). CONCLUSIONS: This one-season pilot prevention study has provided preliminary evidence that finger/hand injuries can be significantly reduced in flag football. Prevention strategies for a longer, prospective, randomised-controlled injury prevention study should include the strict enforcement of the no-pocket rule, appropriate head gear, the use of comfortable-fitting ankle braces and mouth guards, and changing the blocking rules of the game.

Displaced mid-shaft clavicular fractures: is conservative treatment still preferred?

BACKGROUND: A clavicular fracture accounts for 2.6%-5% of adult fractures. Fractures in the middle-third (OTA 15-B) represent 69%-82% of all clavicular fractures. There is no consensus among orthopedic surgeons regarding treatment for these fractures: many support conservative treatment even for displaced middle-third clavicular fractures, while others choose operative treatment. OBJECTIVES: To assess the attitudes of orthopedic surgeons regarding treatment of displaced mid-shaft clavicular fractures. METHODS: We conducted a survey in which we interviewed orthopedic surgeons from various countries during the 2012 EFORT meeting in Berlin. The questionnaire included an X-ray of a displaced middle-third clavicular fracture, as well as questions regarding the surgeon's proposed treatment plan. RESULTS: A total of 177 orthopedic surgeons completed the questionnaire; 49% preferred operative treatment for a displaced middle-third clavicular fracture. Among the orthopedic trauma specialists, 58% suggested operative treatment, as did 82% of shoulder specialists. Most surgeons preferred a locking plate for fixation. CONCLUSIONS: The treatment approach for a displaced middle-third clavicular fracture seems to be evenly split between conservative and operative approaches. The tendency toward operative treatment was.even more remarkable among orthopedic trauma specialists and shoulder specialists who completed the questionnaire. Most surgeons prefer a locking plate as a fixation system for this type of fracture.

The effect of minimally displaced posterior malleolar fractures on decision making in minimally displaced lateral malleolus fractures.

PURPOSE: Despite the high incidence of cases of minimally displaced lateral or posterior malleolus ankle fractures, treatment guidelines are still an issue of controversy. The purpose of this study was to delineate treatment preferences among orthopaedic surgeons in these fractures with and without concomitant posterior malleolus fractures. We hypothesized that concomitant minimally displaced fractures of the posterior malleolus can shift treatment preference towards operative intervention. METHODS: A questionnaire-based study was conducted among orthopaedic surgeons attending the 2012 European Federation of National Associations of Orthopaedics and Traumatology Conference (EFORT) in Berlin, Germany. Treatment preferences were reported for minimally displaced lateral malleolus fractures seen on radiographs and were then compared with treatment preferences when computed tomography (CT) was added revealing a concomitant minimally displaced posterolateral fracture of the posterior malleolus. RESULTS: The cohort comprised 177 surgeons from all six continents. When radiographs showing a minimally displaced lateral malleolus fracture were presented, nonoperative management was indicated by 35 % (62) of participants, whereas 65 % (115) preferred operative intervention. After CT views were added showing an accompanying minimally displaced posterolateral posterior malleolus fracture, 79 % (140) suggested operative intervention and only 21 % (37) advocated nonoperative management (p = 0.03). CONCLUSIONS: Most surgeons prefer open reduction with internal fixation for minimally displaced lateral malleolar fractures. The presence of concomitant posterior malleolus fractures in these cases shifts treatment preference further towards open reduction with internal fixation. Because the posterior malleolus fragment might not be well delineated on standard ankle radiographs, a high index of suspicion is warranted, and the use of CT should be considered in these cases.
