Abstract Background Femoral component subsidence is a known risk factor for early failure of total hip arthroplasty (THA) using cementless stems. The aim of the study was to compare an enhanced recovery concept with early full weight-bearing rehabilitation and partial weight-bearing on stem subsidence. In addition, the influence of patient-related and anatomical risk factors on subsidence shall be assessed. Methods One hundred and fourteen patients underwent primary cementless THA and were retrospectively analyzed. Sixty-three patients had an enhanced recovery rehabilitation with early full weight-bearing and 51 patients had rehabilitation with partial weight-bearing (20 kg) for 6 weeks. Postoperative subsidence was analyzed on standing pelvic anterior–posterior radiographs after 4 weeks and 1 year. Subsidence was measured in mm. Anatomical and prosthetic risk factors (stem size, canal flare index, canal fill ratio as well as BMI and demographic data) were correlated. Results Femoral stem subsidence rate was significantly higher for the group with an enhanced recovery concept compared to the group with partial weight-bearing at the first radiological follow up after 4 weeks [2.54 mm (SD ± 1.86) vs. 1.55 mm (SD ± 1.80)] and the second radiological follow up after 1 year [3.43 mm (SD ± 2.24) vs. 1.94 (SD ± 2.16)] (p < 0.001, respectively). Stem angulation > 3° had a significant influence on subsidence. Canal flare index and canal fill ratio showed no significant correlation with subsidence as well as BMI and age. Conclusion In the present study, cementless stem subsidence was significantly higher in the group with enhanced recovery rehabilitation compared to partial weight-bearing. Small absolute values and differences were demonstrated and therefore possibly below clinical relevance. Anatomical radiological parameters and anthropometric data did not appear to be risk factors for stem subsidence.

Introduction: Femoral neck stress fractures are uncommon and depending on their location, can be at high risk for non-union and significant morbidity.  Their prevalence is higher among runners and military recruits, and women seem to be at higher risk. Methods: A 27-year-old female, who was enrolled in military recruit, reported left side groin pain after a strenuous running exercise. Due to persistent pain an X-Ray was ordered, which revealed no signs of acute lesions. Further imaging studies with CT scan and MRI identified a compression-type femoral neck stress fracture. Results: The patient was submitted to conservative treatment consisting of restricting from full weight-bearing. Six weeks after she initiated partial weight-bearing, becoming asymptomatic at seven months. Follow-up imaging studies revealed union of the fracture. Discussion: This diagnosis should be considered when evaluating military and athlete populations. Early recognition of these injuries is crucial because complication and morbidity rates are high.

From July 1998 to October 2004 forty-seven patients with open tendo-Achilles injuries were treated pull down the proximal tendon with no.1 prolene. In this surgical method no.1 prolene was threaded through the proximal tendon and the same suture material passed through the distal tendon and its bilateral ends were tightened over the rubber button either under the heel or by the sides of the heel. Box sutures apposed cut ends of the tendon. The ankle was placed in the cast in near neutral position. At six weeks the cast was removed and active flexion program was started. Partial weight bearing was allowed at seven weeks and full bearing was allowed at ten weeks after surgery. The average follow up period is 1.8 years. All the patients exhibited full range of motion at the final follow-up. doi: 10.3329/taj.v21i2.3792 TAJ 2008; 21(2): 132-134

Abstract Introduction Aim of this study was to biomechanically compare two different acetabular cup fixation constructs in terms of fracture fixation for displaced acetabular fractures involving the anterior column with hemitransverse fracture under partial and full weight-bearing conditions. Methods Two different reinforcement rings designed as cages for primary THA were biomechanically tested in terms of managing a complex acetabular fracture. Single-leg stance cyclic loading was performed to assess fracture gap movement and fragment rotation. Twelve hemi pelvis Sawbones were divided into two groups: primary THA with acetabulum roof reinforcement plate (ARRP) (n = 6) and primary THA with Burch–Schneider reinforcement cage (BSRC) (n = 6). Results During loading under partial weight-bearing (250 N) fracture gap movement tended to be larger in the BSRC group as compared to the ARRP group. Under full weight-bearing conditions, the ARRP showed 60% significantly less motion (p = 0.035) of the os ilium to os ischii gap compared to BSRC. Fracture gap movements between the os ilium and spina iliaca fragments were significantly reduced by 76% (p = 0.048) for ARRP in contrast to BSRC. The ARRP group also demonstrated significantly less movement in the fracture gaps os ischii to quadrilateral plate (62% reduction, p = 0.009) and quadrilateral plate to spina iliaca (87% reduction, p < 0.001). Significantly less rotational movement of the quadrilateral plate to the os ilium was exhibited by the ARRP group (p = 0.015). Conclusions The presented acetabulum roof-reinforcement plate (ARRP) provides stable conditions at the acetabular component with adequate stabilization of a displaced acetabular fracture.

Category: Midfoot/Forefoot Introduction/Purpose: We report the middle-term outcomes after performing Lisfranc ligament anatomical reconstruction surgery (LARS), using an optimal route of reconstruction based on anatomical measurements of and biomechanical experiments with cadavers. Methods: Subjects included 20 patients (8 female and 12 male, mean age: 35.5 years, mean follow-up period: 35 months) who were diagnosed with Lisfranc joint injury and underwent surgical treatment from 2012 to 2015. Acute case were fourteen cases, chronic cases were 6 cases. The optimal anatomical route of reconstruction was calculated from anatomical measurements obtained from 78 legs of cadavers. The Myerson’s classification and the Kaar’s classification based on stress X-rays were used to classify the injuries at the time of their occurrence. Furthermore, the Japanese Society for Surgery of the Foot (JSSF) Midfoot scale and Stein’s radiographic assessment were used for clinical evaluation postoperatively. Results: According to the Myerson’s classification, Type B1 was one case, Type B2 was 15 cases, Type C1 and Type C2 were each 2 cases. According to the Kaar’s classification, 17 patients had transverse-type injuries and 3 patients had longitudinal-type injury. Partial weight bearing was encouraged within 6 week and return to exercise within 12 weeks. Average JSSF scores at final follow-up were 93.8 points in both examples (85-100) respectively. Joint congruities on X ray were appropriate in most cases but admitted a little diastasis by one case of chronic and one acute case. Conclusion: LARS achieves both static and dynamic stability, does not require removal of the internal fixation material, and enables all patients to support a full load 8 weeks postoperatively. LARS is beneficial for maintaining anatomical reduction, preserving the joint, and shortening the post-therapy period. Our newly developed ligament reconstruction is not only able to acute injuries but also to the chronic injuries.

Background: Stress fracture of the femoral neck is rare in children. Its differential diagnosis includes muscle strain, synovitis, infection, dysplasia, etc. Since physicians rarely see this type of fracture in children, they often overlook it or misdiagnose it.  Case Report: A seven-year-old girl presented to our service with right groin pain following a fall on her right hip 15 days ago. Pelvic and knee radiographs of her right limb showed a fracture line with sclerosis at the femoral neck. Magnetic-resonance imaging (MRI) confirmed the diagnosis of a stress fracture of the femoral neck. We opted for conservative management and gave the patient analgesics and limited weight-bearing with the help of crutches for eight weeks. Three weeks after her first visit, the patient presented with severe limping and inability to bear weight on her right leg. Right hip radiographic imaging showed a varus displaced fracture of the femoral neck, which we managed surgically with an open reduction and internal fixation using plate and screws, followed by immobilization of the right hip with a hip spica cast. Six weeks following the surgery, the patient had no complaints, and the radiographic images showed an appropriate reduction and signs of union. The patient was allowed to start partial weight-bearing for a further six weeks before proceeding to full weight-bearing. Conclusion: Our case emphasizes the importance of considering femoral neck stress fracture in children, through a thorough clinical evaluation and imaging analysis, especially for those carrying classical risk factors. Failure to do so can complicate the disease course and may lead to a displaced fracture requiring more invasive and timely management.

A Sixteen-year-old male had a road traffic accident resulting in crush and loss of lateral two metatarsals of the left foot. The Lateral plantar arch was reconstructed with a vascularized fibula osteocutaneous flap. Flap survived and partial weight-bearing was started by 3 months and full weight-bearing was started 6-months post-surgery. At a 16-month follow-up patient had a normal gait and integrity of the lateral plantar arch was maintained. Vascularized fibula osteocutaneous flap is an excellent option for one-stage reconstruction of the lateral arch of the foot and gives satisfactory results in terms of functions of foot and in avoiding long-term morbidity.

Background: Lower extremity alignment-correcting procedures for unicompartmental osteoarthritis are experiencing a rapid rise. Medial open-wedge high tibial osteotomy (MOW-HTO) thereby represents the most common technique among osteotomies but is limited in cases of severe malalignment. Some cases make a double-level osteotomy necessary. Indications: If planning of malalignment correction using a MOW-HTO results in a mechanical medial proximal tibial angle (mMPTA) of more than 93° (causing an oblique joint line), double-level osteotomy is indicated to avoid nonphysiological knee kinematics. Technique Description: After clinical examination and detailed analysis of malalignment (full-weight-bearing long-leg radiograph: hip-knee-angle [HKA], mMPTA, mechanical lateral distal femoral angle [mLDFA], joint line convergence angle [JLCA]), as well as individualized planning of the correction, the surgical procedure starts with an arthroscopy to evaluate the cartilage conditions and eventually treat intraarticular pathologies. Then, the femoral supracondylar correction is performed (closed wedge, biplanar osteotomy [ to increase bony healing]) according to the presurgical planning by resecting the osteotomy wedge with the measured length. K-wires are placed to check the correction. An angle-stable plate is used for osteosynthesis. The wedge taken out will be used as bone stock for the MOW-HTO afterward. The biplanar open-wedge tibial osteotomy is then performed subsequently using a medial tibial approach and an angle-stable plate. Opening of the osteotomy is then performed and double checked with intraoperative fluoroscopy using an alignment rod. Postoperative partial weight bearing for 6 weeks is recommended. Results: In recent literature, only few publications report on results of double-level osteotomies. Babis et al reports that it is a valuable procedure for patients with large varus deformity. Nakayama et al noted a significant improvement in patient-registered clinical outcomes in early postoperative evaluation of 20 patients. Schröter et al reports on 37 knees and findings include good clinical results, despite progressive osteoarthritis. Discussion/Conclusion: In cases of severe malalignment, adequate axis correction may require a double-level osteotomy. Exact preoperative planning is essential. Results reported in recent publications are promising. By splitting 1 large correction into 2 smaller ones, complications like hinge fracture and delayed bone healing are lowered.

Hip fractures may not be evident on initial radiographs but can be demonstrated with special imaging studies. These “occult fractures” can displace if not promptly treated. In a four-year period, 34 occult fractures around the hip in 33 patients were diagnosed in one general hospital. There were 6 men and 27 women, with a mean age of 74 years (22/92). The medical records and imaging studies were retrospectively reviewed. Two patients presented with a displaced femoral neck fracture one month and 10 days respectively after a fall and initial radiographs resulting normal. In the remaining 31 patients with normal radiographs, 30 fractures were detected with MRI obtained at an average of 6.8 days (0/35) from the onset of symptoms, and one with bone scan. Treatment consisted in partial weight-bearing or surgery, depending on the location and displacement of the fracture. Fractures united in all patients treated non-operatively and in those treated with internal fixation. One patient with a displaced fracture underwent a hip arthroplasty. At an average follow-up of 16.7 months (6/46) all patients remained ambulatory. In a selected group of patients with high suspicion of hip fracture, full-sequence MRI proved to be useful for early diagnosis and localization of an occult fracture around the hip.

(1) Background: High primary stability is important for the long-term survival of cementless femoral stems in total hip arthroplasty (THA). The objective of this study was to investigate the migration pattern of a hydroxyapatite-coated cementless hip stem developed for minimally invasive surgery using model-based radiostereometric analysis (RSA). (2) Methods: In this randomized controlled trial, 44 patients with an indication for cementless primary THA were randomly allocated to receive either the SL-PLUS MIA stem, developed for minimally invasive surgery, or the SL-PLUS stem (Smith & Nephew Orthopaedics, Baar, Switzerland) which served as a control group. Unlimited weight-bearing was permitted postoperatively in both groups. Model-based RSA was performed after six weeks and after 3, 6, 12 and 24 months postoperatively. (3) Results: Mean total stem subsidence at two-year follow-up was 0.40 mm (SD 0.66 mm) in the SL-PLUS group and 1.08 mm (SD 0.93 mm) in the SL-PLUS MIA group (p = 0.030). Stem subsidence occurred during the first six weeks after surgery, indicating initial settling of the stem under full weight-bearing. Both stem designs showed good osseointegration and high secondary stability with no further migration after initial settling. (4) Conclusions: Settling of a cementless straight femoral stem occurs during the first six weeks after surgery under full weight-bearing. Although initial stem migration was higher in the SL-PLUS MIA group, it had no influence on secondary stability. All implants showed good osseointegration and high secondary stability with no signs of implant loosening during this two-year follow-up period.
