A rare cause of foot pain in an adolescent due to os paracuneiforme: a case report and review of the literature.

Os paracuneiforme is an extremely rare accessory ossicle located at the medial aspect of the medial cuneiform bone. Although foot pain secondary to accessory ossicles is well known, symptomatic os paracuneiforme that requires surgical excision is rarely reported in the current literature. Herein, a 12-year-old boy with symptomatic os paracuneiforme is presented, and its clinical and imaging findings as well as the treatment are discussed.

Comparison of magnesium versus titanium screw fixation for biplane chevron medial malleolar osteotomy in the treatment of osteochondral lesions of the talus.

PURPOSE: This retrospective study aimed to compare the clinical and radiological outcomes of patients who underwent biplane chevron medial malleolar osteotomy (MMO) for osteochondral lesions of the talus (OLT), fixed with either magnesium (Mg) or titanium (Ti) screws. METHODS: A total of 22 patients (12 male and 10 female) with a mean age of 40.6 ± 12.5 years (range 18-56 years) who underwent MMO for OLT treatment were included in this retrospective study. Of the 22 patients, MMO was fixed with bioabsorbable Mg screws (Alloy: MgYREZr) in 11 patients, and in the remaining 11 patients (one bilateral) MMO was fixed with Ti screws. All patients were followed up for at least 1 year with a mean of 20.7 ± 8.9 months (range 12-49 months). The American Orthopedic Foot and Ankle Society (AOFAS) scale and the visual analog scale (VAS) were used to evaluate the clinical results. Union of the osteotomy, postoperative displacement and all other complications were followed and analyzed. RESULTS: An improvement in the AOFAS scale and VAS points were recorded in both groups with no statistically significant difference between the groups (p 0.079 and 0.107, respectively). Complete union of the osteotomy was obtained in all patients. One patient in the Ti group required implant removal due to pain and irritation. There were no other significant complications in either group. CONCLUSIONS: The results of this study showed that bioabsorbable Mg compression screws have similar therapeutic efficacy to Ti screws in respect of functional and radiological outcomes in MMO fixation. Bioabsorbable Mg screw is an alternative fixation material which can be safely used for MMO in ankle surgery. LEVEL OF EVIDENCE: Level IV, retrospective case series.

Fixation of medial malleolar fractures with magnesium bioabsorbable headless compression screws: short-term clinical and radiological outcomes in eleven patients.

OBJECTIVE: The purpose of this retrospective study was to evaluate the outcome of medial malleolar fractures treated with magnesium (MgYREZr) bioabsorbable compression screw fixation. MATERIALS AND METHODS: Eleven patients with a medial malleolar fracture (either isolated or accompanied by bimalleolar or trimalleolar ankle fractures) who were treated with magnesium bioabsorbable compression screws between 2015 and 2016 in our hospital were retrospectively evaluated. Patients were monitored with a mean follow-up of 17.3 ± 4.1 months (range 12-24 months). The mechanism of injury was ground level falls in all patients. All fractures were classified as closed fractures. American Orthopedic Foot and Ankle Society's (AOFAS) scale and the visual analog scale (VAS) were used to evaluate the clinical results during the final follow-up. Bone union and a possible loss of reduction were assessed with serial radiographs. Potential complications including revision surgery and infection were recorded and reported. RESULTS: There were 11 patients (4 female, 7 male) with a mean age of 41 ± 21.9 years (range 20-78 years). Six patients had Herscovici type C and five patients had type B fractures. At the final follow-up the mean AOFAS score was 94.9 ± 5.7 points (range 85-100 points) and the mean VAS score was 0.4 ± 1.2 points (range 0-4 points). Radiographic solid union was achieved in all cases. No complications were seen during the follow-up. No patients required implant removal or revision surgery. CONCLUSIONS: This is the first study that investigates the use of bioabsorbable magnesium compression screws in medial malleolar fractures. The results of this study revealed that fixation of medial malleolar fractures with bioabsorbable magnesium compression screws provides adequate fixation with good functional results. LEVEL OF EVIDENCE: Level IV, therapeutic, retrospective case series.

Conversion of hip fusion to total hip arthroplasty: clinical, radiological outcomes and complications in 40 hips.

OBJECTIVE: The purpose of this retrospective study is to report the clinical and radiological outcome of total hip arthroplasty in patients with previous hip arthrodesis. PATIENTS AND METHODS: We retrospectively reviewed 28 (40 hips) prospectively followed patients in whom ankylosed hips were converted to total hip arthroplasty (THA) between 2010 and 2014 in our institution. The average age at the time of the conversion operation was 40.8 ± 9.8 years (range 24-62). The ankylosis had lasted 20.4 ± 13.0 years (range 3-56) before conversion surgery. The etiology of the ankylosis was septic arthritis in 10 (25%), post-traumatic hip osteoarthritis in 8 (20%), developmental hip dysplasia in 6 (15%), rheumatoid arthritis in 6 (15%), primary osteoarthritis in 5 (12.5%) and ankylosing spondylitis in 5 (12.5%) hips. The indications for arthroplasty were intractable low back pain in 14 (50%), hip pain in 24 (85.7%), and ipsilateral knee pain in 19 (67.8%) patients. Harris Hip Score (HHS) was used to rate the clinical results before and after the surgery. Radiographic evaluations included component malposition and loosening. All complications during the study period were recorded. RESULTS: The mean follow-up period was 39.9 ± 10.6 months (range 24-60). The mean preoperative HHS was 33.3 ± 8.6 (range 18-50) and the mean HHS at the final follow-up was 74.9 ± 8.6 (range 52-97). There was a statistically significant increase in HHS (p = 0.0001). HHS was excellent in 1, good in 6, fair in 14 and poor in 7 patients. Increase in HHS was lower than 20 points in one patient (18 points), and one patient required two-staged exchange procedure due to deep infection. Thus, according to our success criteria (increase in HHS more than 20 points, radiographically stable implant, and no further surgical reconstruction), 92.8% (26/28) of patients had benefit from the surgery. Trendelenburg sign was positive in 12 hips. There was limb length inequality in 11 patients (mean 0.5 cm, range 1-3 cm). No patients had heterotopic ossification, sciatic nerve palsy or dislocation. There were five intra-operative fractures of the greater trochanter that were treated with cable wiring. One patient had trochanteric avulsion injury and was treated with trochanteric grip and cables. One patient (2.5%) had deep infection one year after the conversion THA and was treated with two-staged exchange procedure. CONCLUSION: Conversion hip arthroplasty is an effective treatment method which provides functional recovery and patient satisfaction. However, a proper surgical technique and planning is necessary to minimize the complications.

Removal of a bent intramedullary nail in lower extremity: report of two cases and review of removal techniques.

Removal of a bent intramedullary nail (IMN) is a rare but challenging orthopedic problem. Several removal techniques have been described up to date; however, there is no extensive review and no algorithm to manage these cases in current literature. The purpose of this paper is to present two cases that presented with bent IMN and provide an algorithm for management of this rare complication.

Isolated Adult Tillaux Fracture Associated With Volkmann Fracture-A Unique Combination of Injuries: Report of Two Cases and Review of the Literature.

Avulsion fractures of the anterior inferior tibiofibular ligament from its tibial attachment, Tillaux fractures, are usually seen in adolescents during the interval of the distal tibial epiphyseal closure. However, this pattern of fracture is rare in adult patients, because the ligaments will usually fail before the bone fails. Avulsion fracture of the posterior inferior tibiofibular ligament from its tibial attachment, Volkmann fracture, is the posterolateral counterpart of a similar injury. In the present study, the cases of 2 adult patients with simultaneous Tillaux and Volkmann fractures are reported and the mechanism of injury, diagnosis, and treatment discussed. This fracture pattern is extremely rare and, to the best of our knowledge, has not been previously reported.

Publication rate of abstracts presented at the emergency medicine congresses held by the European Society for Emergency Medicine (EUSEM) in 2011 and 2012.

PURPOSE: The purpose of this study was to assess the publication rate of the abstracts presented at the 6th Mediterranean Emergency Medicine Congress, 2011 and the 7th European Congress on Emergency Medicine, 2012. MATERIALS AND METHODS: All abstracts, both posters and oral presentations, from the international emergency medicine congresses held by the European Society for Emergency Medicine (EUSEM) in 2011 and 2012 were identified. To establish whether these abstracts were subsequently published in peer-reviewed medical journals, the names of all the authors and the title of the abstracts were searched for in the databases of Clinical Key/Elsevier, EBSCO Discovery Service, MD Consult, Science Direct, Scopus, EMBASE, Medscape, Google Scholar and local ULAKBIM. The year of publication, consistency of author names and titles, the type of study, the journals in which papers were published and countries from which reports were submitted were all recorded. RESULTS: A total of 1721 abstracts were examined; 626 from 2011 (307 oral presentations and 319 posters) and 1095 from 2012 (154 oral presentations and 941 posters). Of all abstracts in 2011, 172 (27.5%) and of all abstracts in 2012, 265 (24.2%) were subsequently published as full-text reports in peer-reviewed journals. Of the 172 papers published in 2011, 152 (88.4%) were accepted by Science Citation Index (SCI) and/or SCI Expanded (SCI-E) journals and 155 (58.5%) of 265 papers were accepted by SCI and/or SCI-E journals in 2012 (p=0.0001). CONCLUSIONS: The publication rate of abstracts submitted to international emergency medicine congresses held by EUSEM over those 2 years was low compared with that of abstracts presented in other emergency medicine congresses. Presenters should be encouraged to send their studies to peer-reviewed journals. During the selection process by the scientific panel, constructive critics should be notified to the presenters instead of simply accepting or rejecting the studies that submitted to the congress, which may increase the subsequent publication rate.

Intramedullary nailing versus minimally invasive plate osteosynthesis for distal extra-articular tibial fractures: a prospective randomized clinical trial.

PURPOSE: The purpose of this randomized clinical trial is to compare intramedullary nailing (IMN) versus minimally invasive plate osteosynthesis (MIPO) for the treatment of extra-articular distal tibial shaft fractures. MATERIALS AND METHODS: Twenty-five consecutive patients with distal extra-articular tibial fractures which were located between 4 and 12 cm from the tibial plafond (AO 42A1 and 43A1) were randomly assigned into IMN (n: 10) or MIPO (n: 15) treatment groups. All patients were followed for at least 1 year. Foot function index, time to weight bearing, union time, duration of operation, length of incision, intra-operative blood loss, intra-operative fluoroscopy time, rotational and angular malalignment, rate of infection, secondary interventions and complications were compared between groups. RESULTS: All patients completed the trial and were followed with a mean of 23.1 ± 9.4 months (range 12-52). Foot function index, weight bearing time, union time, rate of malunion, rate of infection and rate of secondary interventions were all similar between groups (p = 0.807, p = 0.177, p = 0.402, p = 0.358, p = 0.404, p = 0.404, respectively). Intra-operative blood loss, length of surgical incision, radiation time and rotational malalignment were higher in the IMN group (p = 0.012, p = 0.019, p = 0.004 and p = 0.027, respectively). CONCLUSIONS: Results of our study showed that both treatment methods have similar therapeutic efficacy regarding functional outcomes and can be used safely for extra-articular distal tibial shaft fractures, and none of the techniques had a major advantage over the other.

A comparison of telephone interview versus on-site completion of Lysholm knee score in patients who underwent arthroscopic ACL reconstruction: are the results equivalent?

INTRODUCTION: The purpose of this study was to compare two different modes of administration (telephone versus face to face) for Lysholm knee score (LKS) to test their multi-mode equivalence and reliability. MATERIALS AND METHODS: Two LKSs were obtained in 100 patients who underwent ACL reconstruction surgery. First LKS was completed through telephone interview, and second LKS, which was at least 2 weeks later, was completed face-to-face interview at the hospital. To analyze the test-retest reliability, the relative level of agreement between the two modes of administration for LKS was calculated using interclass correlation coefficient (ICC) in 95 % confidence interval. RESULTS: The mean LKS was 93.01 ± 9.12 (range 59-100) at telephone interview and 93.56 ± 7.93 (range 59-100) at face-to-face interview (p = 0.130). Both the total point and the each item's point were statistically similar (p < 0.05 for each item). The total score was same in 66 (66 %) subjects. The mean difference between two scoring was only 1.83 ± 3.14 points (range 0-15). However, eight (8 %) patients were assigned to different grading groups (excellent, good, fair, and poor). The overall LKS and the each item of the LKS had acceptable test-retest reliability [ICC = 0.954 (95 % CI 0.931-0.969)]. CONCLUSIONS: LKS can be reliably completed through telephone interview, which would provide accurate data similar to face-to-face interview. Researchers can design studies using telephone interview as a mode of administration for LKS or use mix-mode designs.

Functional outcomes and complications after surgical repair of triceps tendon rupture.

OBJECTIVE: The purpose of this study was to present the functional outcomes and complications after primary repair of triceps tendon ruptures (TTR). PATIENTS AND METHODS: A retrospective review was performed on eight patients (six males, two females) who underwent transosseous suture repair for TTR. Mayo elbow score, range of motion, muscle strength and patient satisfaction were evaluated after at least 1-year follow-up. RESULTS: The mean age of the patients was 25.1 years (range 16-42). The mechanism of injury was a sports injury in three patients, simple fall (fall on outstretched hand) in four and motorcycle accident in one patient. Two patients had associated radial head fracture, and one had a radial head fracture and trochlear fracture, and one patient had a medial epicondyle fracture. In two patients the diagnosis was missed at the initial admission to ED (delay, 20 and 75 days). Only one patient, who was a bodybuilder, had a history of anabolic steroid use, and the rest had no underlying disease or a predisposing factor for TTR. One of the patients with radial head fracture (displaced three parts) underwent simultaneous fixation using two headless screws. Patients were followed up for a mean of 18.8 months (range 12-26). At the final follow-up, all patients were satisfied with the treatment and the Mayo elbow score was excellent in six patients and good in two patients. There was 5° extension loss in two patients. Triceps muscle strength was 5/5 in all patients. Ulnar nerve entrapment occurred in one patient, so ulnar nerve release and anterior transposition were performed 3 months after surgery. Posterior interosseous nerve palsy occurred in one patient who underwent simultaneous radial head fracture fixation, but eventually returned back to normal 3 months postoperatively. All patients returned to their previous level of activity and occupation. CONCLUSION: Transosseous suture technique is a safe and effective treatment method for acute TTR with a low rate of complications and excellent functional outcomes. LEVEL OF EVIDENCE: Retrospective case series, Level IV.

The prevalence of knee injuries ipsilateral to tibial shaft fractures and their impact on clinical outcome.

OBJECTIVE: The purpose of this prospective study was to examine the prevalence of occult knee injuries in patients with ipsilateral tibial shaft fractures and determine their impact on clinical outcome. MATERIALS AND METHODS: Preoperative knee MRI examination was performed in 41 patients (42 knees) with isolated tibial shaft fractures. Menisci, cruciate ligaments, collateral ligaments, extensor mechanism, osteochondral lesions, bone contusions and knee effusion were evaluated. All patients were treated with reamed and locked intra-medullary tibial nailing without an additional surgical procedure for knee injuries. All patients were followed to at least fracture union and were evaluated with knee examination and Lysholm knee score. RESULTS: Of the 42 knees, 41 (97.6 %) showed at least one defined injury around the knee. There was only one patient who had totally normal knee MRI findings. One or more ligamentous injuries of the knee were identified in 35 (83.3 %) of the knees. Five patents (11.9 %) had medial meniscal tear in posterior horn. Extensor mechanism injuries were seen in two patients. Mild to marked joint effusion was observed in 35 (81 %) knees. Twenty-two knees demonstrated bone bruise; femoral condyle (n = 7), tibial plateau (n = 12), patella (n = 2) and fibular head (n = 1). No patients had osteochondral lesion. Patients were followed with a mean of 13.2 ± 3.6 (range 8-22) months. Clinical knee examination revealed Grade II (+) anterior drawer test in two patients. The mean Lysholm knee score was 99.1 ± 2.14 (range 91-100) at the final follow-up. CONCLUSIONS: Ipsilateral intra-articular, extra-articular or combined knee injuries may occur at the time of injury with tibial shaft fractures. However, most of these injuries are not clinically relevant and heal without any sequel or remain asymptomatic late after fracture union. Routine use of preoperative knee MRI examination in patients with tibial shaft fractures is not necessary.

Carpometacarpal dislocation of the thumb associated with fracture of the trapezium.

Carpometacarpal dislocation (CMC) of the thumb associated with fracture of trapezium is an extremely rare injury, with only 12 cases that sustained similar injuries reported in the literature. In this article, another patient with this rare injury was reported, and all previously published cases were extensively reviewed. The presented case and all previously published cases had a longitudinally oriented trapezium fracture, which is naturally unstable and almost always associated with dislocation of the CMC joint. In contrast to previous descriptions, we believe that CMC joint dislocation and trapezium fracture are not two distinct pathologies that occur simultaneously by chance but share cause and consequence.

Fatty degeneration and atrophy of the rotator cuff muscles after arthroscopic repair: does it improve, halt or deteriorate?

OBJECTIVE: The purpose of this study was to evaluate the changes in fatty degeneration and atrophy of rotator cuff muscles after arthroscopic repair. We further assessed the factors affecting the functional outcomes and integrity of the rotator cuff. MATERIALS AND METHODS: One hundred and two prospectively followed patients who underwent single-row arthroscopic repair for full-thickness rotator cuff tears between 2008 and 2010 in our institution were included. All patients underwent shoulder MRI examination before the arthroscopic repair and at the final follow-up at least 2 years after the surgical repair. Supraspinatus muscle atrophy was measured and evaluated according to the Thomazeau classification. The fatty degeneration of the cuff muscles was graded according to the Goutallier classification. Functional outcomes were assessed with the Constant shoulder score. The changes in fatty degeneration and atrophy were analyzed during the treatment period. Correlation coefficients (Pearson r) and stepwise, multiple linear regression were used to determine the relationship between the outcome variables (final Constant score and integrity of the cuff), and the predictor variables, age, sex, follow-up duration, initial muscle atrophy, final muscle atrophy, initial fatty degeneration and final fatty degeneration. RESULTS: Of the 102 patients reviewed, 87 patients responded and concluded the final clinical follow-up and MRI examination (85.2 % follow-up rate). There were 67 females and 20 males with a mean age of 62.5 ± 8.3 years (range 40-80 years). Mean follow-up period was 30.1 ± 5.8 months (range 24-43 months). At the final follow-up, the mean Constant shoulder score was 94.2 ± 8.2 (range 70-100), and 66 (75.9 %) patients rated as excellent, 14 (16.1 %) as good, and 7 (8.0 %) as fair. No patient had poor results. There was re-rupture in 26 (29.9 %) patients on final MRI examination. No patient had improvement in muscle atrophy and fatty degeneration. The atrophic changes between intact tendon and re-rupture cases were statistically similar (p = 0.300). The deterioration of fatty degeneration was significantly higher in the re-rupture group (p = 0.0001). The Constant shoulder score was significantly lower in patients with re-rupture (97.4 ± 5.0 versus 86.6 ± 9.3, p = 0.001).Multiple stepwise regression analysis showed that the Constant score was dependent on the final integrity of the tendon and the size of the tear (R (2) 0.420, p 0.001). The final integrity of the tendon was dependent on the age of the patient, initial and final fatty degeneration of the cuff muscles and the size of the tear (R (2) 0.669, p 0.001). CONCLUSION: Initial muscle atrophy and fatty degeneration did not improve even after a successful rotator cuff repair where the tendon anatomic integrity was maintained for at least 2 years. It may continue to deteriorate, and the best possibility was preservation of the preoperative status. On the other hand, in cases of re-rupture, fatty degeneration and atrophy continued to worsen significantly. The factors affecting tendon integrity were found to be the age of the patient, the size of the tear and the severity of preoperative fatty degeneration in the rotator cuff.

Comparison of patient positions without traction table for proximal femoral nailing: Supine, semilithotomy and lateral decubitus positions.

BACKGROUND: Femur intertrochanteric fractures are performed commonly in a supine position with a traction table. There is a challenge in obtaining traction tables, especially in low- and middle-income countries. However, there is still a debate on which position should be preferred if the traction table cannot be obtained. METHODS: A total of 123 patients who were treated for femur intertrochanteric fracture (AO/OTA A1 or A2) using cephalomedullary nail (CN) were retrospectively analyzed. All three positions without traction table (supine:25 patients, semilithotomy:36 patients and lateral decubitus:62 patients) were compared according to preparation time, surgical time, Tip-Apex distance (TAD), zones of lag screw placement, collodiaphyseal angle (CDA), CDA difference (∆ CDA), postoperative posterior sag, medial cortical support and Baumgardner reduction quality criteria. RESULTS: The preparation time was longer in the semilithotomy group, and surgery time was longer in the supine position group. There was no difference according to total time, surgical time, TAD, CDA difference (∆ CDA), postoperative posterior sag, medial cortical support and Baumgardner reduction quality criteria. Target lag screw placement is superior in supine and semilithotomy group than lateral decubitus. CONCLUSION: This study concluded that there was a difference in preparation time, surgery time and optimal lag screw placement in the lateral plane between groups. The surgeon may prefer all three methods according to patient benefit and surgeon familiarity.

Is there a relationship between attention deficit/hyperactivity disorder and Osgood-Schlatter disease?

PURPOSE: The purpose of this prospective study is to investigate the relationship between Osgood-Schlatter disease (OSD) and attention deficit/hyperactivity disorder (ADHD). METHODS: Seventy-four children with a diagnosis of OSD were referred to child and adolescent psychiatry department for the evaluation of ADHD. Diagnostic and Statistical Manual of Mental Disorders was used for diagnostic criteria. RESULTS: Diagnosis of ADHD was made in 56 (75.6 %) out of 74 children. CONCLUSIONS: Results of this study suggest that ADHD is a significant risk factor for OSD. During the evaluation of a patient with OSD, a thorough history should be obtained about the behavioral symptoms that indicate underlying ADHD. In case of suspicion, these patients should be referred for an additional evaluation by a child psychiatrist. LEVEL OF EVIDENCE: II.

Inter- and intraobserver reliability of the Crowe and Hartofilakidis classifications in the assessment of developmental dysplasia of the hip in adult patients.

BACKGROUND: The purpose of this study is to investigate the inter- and intraobserver reliability of Crowe and Hartofilakidis classifications in the assessment of developmental dysplasia of the hip in adult patients. MATERIALS AND METHODS: Two consultant orthopedic surgeons classified 141 dysplastic hips on 103 standard anterior-posterior pelvis radiographs according to the Crowe and Hartofilakidis classifications. Assessments were performed in random order by each observer on two separate occasions, at least 4 weeks apart. Kappa statistics were used to establish a relative level of agreement between observers for the two readings and between separate readings by the same observer. RESULTS: At the first readings, interobserver reliability analysis revealed kappa coefficient of 0.71 for the Crowe classification and 0.54 for the Hartofilakidis classification. At the second reading, the kappa coefficient was 0.72 for the Crowe classification and 0.75 for the Hartofilakidis classification. Intraobserver reliability analysis revealed kappa coefficients of 0.71 for the Crowe and 0.80 for the Hartofilakidis classification for observer A, and 0.76 and 0.70 for observer B. CONCLUSIONS: In conclusion, we have found substantial inter- and intraobserver agreement for Crowe classification and substantial to moderate agreement for Hartofilakidis classification in this study. Both classification systems assess the different aspects of developmental dysplasia of hip in adults. Each system has advantages and disadvantages. We suggest using both of these classifications together to increase the accuracy.

Treatment of high hip dislocation with a cementless stem combined with a shortening osteotomy.

INTRODUCTION: The purpose of this study was to review the clinical and radiographic outcomes and report the major complications in a group of hips with Crowe type IV developmental dysplasia that underwent reconstruction with a cementless total hip arthroplasty and a transverse subtrochanteric shortening osteotomy fixed with locking compression plate and screws. METHOD: Fifteen consecutive patients (21 hips) who had coxarthrosis secondary to Crowe Group IV developmental dysplasia of the hip were treated with a cementless prosthesis and a transverse subtrochanteric osteotomy fixed with locking compression plates at a mean age of 41. The mean follow-up period was 5 years. The acetabular cup was placed in the position of the anatomical hip center in every patient. Subtrochanteric femoral shortening osteotomy was fixed with plates and screws in all patients. RESULTS: The mean Harris hip score improved from 36.2 ± 9.8 points to 90.8 ± 2.5 points. Trendelenburg sign was positive in seven hips and two patients complained about continuing anterior thigh pain at the final follow-up. There was no infection. No cases of nonunion were encountered. Two patients had dislocation on early postoperative period (15th and 20th postoperative day). Of these patients, femoral head was changed to 28 mm with stem revision in one patient, and one had acetabular component revision with use of constrained acetabular liner. There was one permanent sciatic nerve palsy. One patient had implant related pain during lying laterally. Plate and screws were removed at postoperative 16th month. CONCLUSION: Cementless total hip arthroplasty combined with subtrochanteric osteotomy for the treatment of patients with Crowe Group IV developmental dysplasia of the hip is an effective technique to reduce the hip to its original acetabular location and restore the rotational deformities. Plate and screw fixation is a viable option for a secure and stable fixation of femoral stem after subtrochanteric osteotomy.

Management of a wild boar wound: a case report.

Injuries caused by wild boar attacks are rare. A 34-year-old male shepherd sustained injuries caused by a wild boar attack, and was brought to our emergency department. The patient had 2 skin and deep tissue lacerations on the posterior aspect of his thigh. Herein, we discuss the clinical management of a wild boar bite wound with a review of the literature.

Single versus double screw fixation for the treatment of scaphoid waist fractures: Finite element analysis and preliminary clinical results in scaphoid nonunion.

OBJECTIVES: This study aims to compare the single versus double screw fixation of scaphoid waist fractures using finite element analysis, and to present the preliminary clinical results of double screw fixation in a consecutive series of patients with scaphoid nonunion. PATIENTS AND METHODS: A transverse scaphoid waist fracture (Herbert type B2) model was fixed with either single or double cannulated compression screws. Displacement and rotation of the fragments were performed using three-dimensional finite element analysis in three different wrist positions. A retrospective review was performed on 13 male patients (mean age 31.6±12.8 years; range, 17 to 64 years) who underwent double screw fixation for an established scaphoid nonunion in our clinic between January 2015 and December 2017. Assessment of union was established with serial plain radiographs in eight patients and with wrist computed tomography in five patients. Clinical evaluation was performed using the Mayo wrist score and visual analog scale (VAS). RESULTS: In all wrist positions, the displacement of the fracture gap in double screw fixation in all planes (x, y, and z) was less than in single screw fixation. Similarly, rotation of the fracture fragments around the longitudinal axis of the scaphoid was lower in double screw fixation. Complete union was obtained in all patients. The mean time to union was 5±0.75 months (range, 4 to 6 months). The mean VAS was 0.8±0.9 (range, 0 to 3). Mayo wrist score was 91±6.9 (range, 80 to 100) at the final follow-up. CONCLUSION: Double-screw fixation technique may be a solution to reduce the rate of scaphoid nonunion in unstable type B2 scaphoid fractures or nonunion.
