Hip Arthroplasties

Background: Hip arthroplasties are increasing worldwide resulting in an increasing number of periprosthetic fractures. These fractures are difficult to treat with various the different fixation or revision options described, many of which have high complication rates. Purpose: To investigate whether our described method of treating periprosthetic fractures is an effective, safe and reproducible method of treating patients. Methods: We describe the largest series of a cable plate fixation system combined with a single cortical strut allograft to treat patients with periprosthetic fractures of the hip (Unified Classification System B1 and selected B2, C and D). Results: Between July 2006 and March 2015, 28 patients were treated using this method. The mean follow-up was 2.2 years (3 months to 9 years). The mean Oxford Hip Score (OHS) at final follow-up was 32 and the mean modified Harris Hip Score (mHHS) 67. There were 3 complications including 1 failure that required revision surgery, 1 case of infection successfully treated with debridement, antibiotics and retention, and a case of discomfort from the metalwork which we managed conservatively. Conclusion: This method of anatomical restoration of the femur with dual-plane fixation is a highly effective method of treating this complex group of patients, and should be considered as a first line of treatment. It shows that there is a role for successful treatment with internal fixation of certain B2, C and D fractures with this technique.

Hip Arthroplasties

Aims Short-stemmed femoral implants have been used for total hip arthroplasty (THA) in young and active patients to conserve bone, provide physiological loading, and reduce the incidence of thigh pain. Only short- to mid-term results have been presented and there have been concerns regarding component malalignment, incorrect sizing, and subsidence. This systematic review reports clinical and radiological outcomes, complications, revision rates, and implant survival in THA using short-stemmed femoral components. Materials and Methods A literature review was performed using the EMBASE, Medline, and Cochrane databases. Strict inclusion and exclusion criteria were used to identify studies reporting clinical and radiological follow-up for short-stemmed hip arthroplasties. Results A total of 28 studies were eligible for inclusion. This included 5322 hips in 4657 patients with a mean age of 59 years (13 to 94). The mean follow-up was 6.1 years (0.5 to 20). The mean Harris Hip Score improved from 46 (0 to 100) to 92 (39 to 100). The mean Oxford Hip Score improved from 25 (2 to 42.5) to 35 (12.4 to 48). The mean Western Ontario & McMaster Universities Osteoarthritis Index improved from 54 (2 to 95) to 22 (0 to 98). Components were aligned in a neutral coronal alignment in up to 90.9% of cases. A total of 15 studies reported component survivorship, which was 98.6% (92% to 100%) at a mean follow-up of 12.1 years. Conclusion Short-stemmed femoral implants show similar improvement in clinical and radiological outcomes compared with conventional length implants. Only mid-term survivorship, however, is known. An abundance of short components have been developed and used commercially without staged clinical trials. Long-term survival is still unknown for many of these components. There remains tension between innovation and the moral duty to ensure that the introduction of new implants is controlled until safety and patient benefit are demonstrated. Implant innovation and subsequent use should be driven by proven clinical outcomes, rather than market and financial forces, and ethical practice must be ensured.

Objectives: To determine the rate of return to sport (RTS) in high-level athletes undergoing bilateral hip arthroscopy and report minimum 1-year patient-reported outcomes (PROs) for this cohort. We hypothesized that RTS rates, as well as sport-specific PROs, will be lower than the rates and scores previously reported in the literature for unilateral hip arthroscopy. Methods: Data were prospectively collected on all patients undergoing hip arthroscopy at our institution from November 2011 to July 2018. Patients were included if they underwent bilateral hip arthroscopy and were either a high school, collegiate, or professional athlete prior to their first surgery. RTS was defined as a patient’s return to competitive participation in their respective sport. Additional PROs, including modified Harris Hip Score (mHHS), nonarthritic hip score (NAHS), and Hip Outcome Score-Sports Specific Subscale (HOS-SSS), as well as complication rates and future surgeries were documented and compared for all patients. Results: A total of 87 patients met inclusion criteria, for which follow-up was available for 82 (94.3%). At latest follow-up, 44 (53.7%) patients returned to sport. Of patients returning, 56% did so at the same level or higher. The most common reasons for not returning to sport were due to graduation/lifestyle change (47.4%) and hip symptoms (44.7%). Patients returning to sport had significantly higher PROs at latest follow-up relative to those who did not return, including for mHHS (93.7 vs. 87.5), NAHS (94.4 vs. 88.2), HOS-SSS (90.9 vs. 78.2) (P < 0.05). Rates of achieving PASS and MCID for mHHS were not significantly different. However, for HOS-SSS, patients who returned had significantly higher rates of achieving the MCID and PASS. Conclusion: Rates of RTS after bilateral hip arthroscopy are lower than those after unilateral hip arthroscopy. When comparing patients that returned to sports and those who did not return, we show that although both groups show a significant improvement in PROs following surgery, those that returned to sport achieved significantly higher scores in all outcome measures. In addition, patients returning to sports showed a significantly higher rate of attaining MCID and PASS scores for the HOS-SSS, possibly attesting to the validity of this score and its thresholds.

Introduction and methods: From January 2004 to December 2008, 188 total hip arthroplasties were performed using a cemented dual mobility cup. 174 patients were available for final analysis. Their mean age was 76.8 (range 54-98 years). The mean follow-up was 7.7 years (range 5-10 years). Results: There were no dislocations. Survivorship rates of the femoral and acetabular components were 100% at a minimum of 5 years. At the latest follow-up, the mean Harris Hip Score significantly increased from 31.6 (only arthritic patients) points preoperatively to 84.5 points. No patients had progressive osteolysis, component migration, or loosening on radiographs. 2 patients presented with periprosthetic fractures treated conservatively. 2 patients presented with infection treated without implant removal and 1 patient presented with transient femoral palsy. Conclusions: The results of this consecutive series confirmed the good performance of the cemented dual mobility cup at mean 7.7 years follow-up with no revision and no dislocations.

Abstract Background: To evaluate the clinical features and results of the revision total hip arthroplasties (THA) in patients with catastrophic failures and metallosis. Methods: Fifteen hips of 14 patients with catastrophic failure and metallosis in hip arthroplasties were evaluated. They were followed for at least 4.2 years after the revision THA. Clinical evaluation was performed using Harris hip score. Osteolysis, loosening or presence of metallosis was evaluated with standard radiographs. Metallosis was evaluated intraoperatively according to the metallosis severity classification. Results: The mean time from failure until revision surgery was 9.4 years. It was observed that in the primary THA, metal-on-ceramic (MoC), ceramic-on-ceramic (CoC) and metal-on-conventional polyethylene (MoCPE) bearings were used in 1, 3 and 11 hips, respectively. Grade III metallosis was observed in all patients during revision surgeries. The mean Harris hip score increased from 55 points before revision THA to 75 points at the final follow-up. In revision arthroplasty, MoCPE and CoC bearings were used in 13 and 2 hips, respectively. The femoral stem was replaced in 5 hips. All acetabular cups, except that of one hip, were revised. Conclusions: Revisions of THAs with catastrophic failures and metallosis are quite challenging. Routine follow-up of arthroplasty patients is beneficial to examine for osteolysis, loosening, and asymmetric wear.

Background:The acetabular labrum plays important roles in proprioception, nociception, synovial fluid seal effect, and static and dynamic joint stability and as a shock absorber. Clinical and radiographic risk factors for unsalvageable labral tear in femoroacetabular impingement (FAI) are not well established.Purpose:To identify predictors of unsalvageable labral tear during initial hip arthroscopic management of FAI.Study Design:Case-control study; Level of evidence, 3.Methods:Patients were included who underwent primary hip arthroscopic treatment for FAI between March 2009 and March 2014. Patients were excluded who had <2-year follow-up, underwent bilateral surgery, or had a history of surgery, osteoarthritis (Tönnis grade 2 or 3), and other diagnoses, including lateral center-edge angle <25° diagnosed as developmental hip dysplasia. Patients were divided into 2 groups according to their labral condition: reconstruction and refixation. Unsalvageable labral tear was defined as any irreparable labral tear, including severe degenerative tear, frayed labrum, labral ossification, flattened labrum, and failed prior repair during surgery. Univariate and multivariate analyses identified risk factors for segmental labral reconstruction. Patient-reported outcome scores and postoperative revision rates were also assessed.Results:Twenty-five hips (18 male, 7 female) and 126 hips (65 male, 61 female) were included in the reconstruction and refixation groups, respectively. The mean ± SD ages were 52.6 ± 15.0 and 36.5 ± 16.1 years in the reconstruction and refixation groups, respectively. In the reconstruction group, the mean modified Harris Hip Score significantly improved from 67.3 ± 14.9 preoperatively to 95.0 ± 8.1 at final follow-up ( P < .001), and the mean Nonarthritic Hip Score improved from 63.0 ± 18.3 preoperatively to 89.5 ± 10.1 at final follow-up ( P < .001). In the refixation group, the mean modified Harris Hip Score significantly improved from 69.2 ± 18.6 preoperatively to 93.0 ± 11.2 at final follow-up ( P < .001), and the mean Nonarthritic Hip Score improved from 60.7 ± 18.8 preoperatively to 88.6 ± 15.0 at final follow-up ( P < .001). No significant difference was noted in patient-reported outcome scores and revision hip arthroscopy rates. The rate of conversion of total hip arthroplasty was higher in the reconstruction group than in the refixation group. Risk factors for unsalvageable labral tear were age ≥45 years (odds ratio [OR], 8.83; P < .007), body mass index ≥23.1 kg/m2(OR, 13.05; P < .001), and vertical center anterior angle ≥36° (OR, 19.03; P < .001). Furthermore, in this study, unsalvageable labral tears were present in cases with at least 2 of the 3 risk factors.Conclusion:Age ≥45 years, body mass index ≥23.1 kg/m2, and vertical center anterior angle ≥36° are risk factors for unsalvageable labral tear at initial hip arthroscopic surgery for patients with FAI.

Abstract Background: Dorr Type C femoral bone exhibits a wide, stovepipe-shaped femoral canal and thin cortices in the proximal femur. Dorr C bone combined with severe osteoporosis is an important challenge in primary hip arthroplasty. In this study, we assessed the effects of short metaphyseal fitting cementless stems on preformatted primary total hip arthroplasties in young adult osteoporotic patients with this femoral presentation.Methods: A total of 42 hip arthroplasties were performed in 35 young patients (range, 20 to 36 years) using a short Tri-lock bone preservation metaphyseal-fitting cementless femoral component between 2012 and 2017. The mean age at surgery of the 27 male (33 hips) and 8 female (9 hips) patients was 27.5 ± 3.7 years (range 20.3 to 35.8 years). The mean body mass index (BMI) was 20.2 kg/m2 (range, 16.8–23.2 kg/m2). According to Dorr’s criteria, all 42 femora were classified as type C bone and all femurs suffered from severe osteoporosis (Singh index≤3). Results: The mean follow-up period was 5.5 ± 1.1 years (range, 3.0–8.0 years). The clinical and functional results improved for the Harris hip score, WOMAC, and UCLA activity scores. The Harris Hip score improved from 48.0 ± 8.0 (range 38.0 to 61.0) preoperatively to 87.0 ± 9.0 (range 77.0 to 92.0) at 12 months after surgery and 91.0 ± 8.0 (range 85.0 to 98.0) at final follow-up. The preoperative UCLA activity score was 3.0±0.5 points (range, 1.0–4.0 points), which significantly improved to 7.5±0.7 points (range, 6.0–8.0 points) at the final follow-up. No patient exhibited thigh pain at the final follow-up. The mean stem-to-canal fill percentages were 97% ± 2.1% (anteroposterior view at midstem). For stem alignment, 40 hips (95.2%) of the femoral stem were positioned neutral to 3° of varus with reference to the femoral shaft axis. The remaining two were positioned at 4° varus to 4° valgus. Radiographic evaluation showed good osteointegration of the implants in follow-up.Conclusions: Based on the tapered-wedge design and proximal porous coating, the shortened tapered conventional stem can achieve reliable stability through neck filling and metaphyseal fixation, which does not depend on the isthmus hoop stress. This stem was suitable in severe osteoporotic patients with Type C bones in young adults who presented with a correspondingly straightened femoral canal with a wide isthmus and thin cortex.

In revision arthroplasty, MoCPE and CoC bearings were used in 13 and 2 hips, respectively. The femoral stem was replaced in 5 hips. All acetabular cups, except that of one hip, were revised. Conclusions Revisions of THAs with catastrophic failures and metallosis are quite challenging. Routine follow-up of arthroplasty patients is beneficial to examine for osteolysis, loosening, and asymmetric wear.

The purpose of this study was to review retrospectively the primary total hip arthroplasties operated upon with the cementless Wagner self-locking stem in patients with Type C femoral bone. Twenty-five total hip arthroplasties were performed in 23 patients aged ≥60 years using a cementless Wagner self-locking femoral component between 2006 and 2011. According to Dorr's criteria, all 25 femora were classified as type C bone. Mean follow-up period was 62 months (range, 47–85 months). Average Harris Hip score preoperatively was 46 ± 9 (range, 39–62) and at the last follow-up was 90 ± 9 (range, 83–98). The mean proximal stem-to-canal fill percentage was 95% ± 3.5% (anteroposterior view) and 90% ± 2.8% (lateral view) and the mean distal canal fill was 93% ± 4.5% (anteroposterior) and 92% ± 3.9% (lateral). Radiographic evaluation demonstrated good osteointegration of the implants in follow-up. Based on the long-straight cylindrical tapered stem design, the cementless Wagner SL stem can achieve reliable stability by close apposition of stem and wide stovepipe femoral canal from metaphysis to diaphysis in Type C bone.

Background Glenoid rim fractures are uncommon and generally associated with high complication rates. The most common treatment techniques include screw or anchor fixation. Here, we introduce a new fixation method to treat Ideberg type 1 A fractures. Methods A retrospective analysis was performed on patients treated with open reduction and plate fixation for Ideberg type 1 A fractures. The active range of motion capacity of both shoulders was recorded postoperatively. Constant-Murley score and Oxford disability index scores were used as outcome tools. Results Five patients (three men and two women) were evaluated; their mean age was 56 years (standard deviation (SD), 10 years). The mean follow-up period was 25 months (range, 6–69 months); all fractures healed radiologically during the follow-up period. The mean Constant-Murley score was 80.36 (SD 11.01); the mean Oxford disability index was 37 (SD 9). The subsequent flexion and external rotation of the injured shoulders were similar to those of the uninjured side (injured vs. uninjured side: flexion, 176 ± 5.4 vs. 178 ± 4.4; external rotation, 48 ± 10.9 vs. 60 ± 0). No patient showed signs of osteoarthritis, stiffness, instability, or chronic pain at the last follow-up. Discussion Open reduction and internal fixation with a plate is suitable for Ideberg type 1A glenoid fractures.

Abstract Background Dorr type C femoral bone exhibits a wide, stovepipe-shaped femoral canal, and thin cortices in the proximal femur. Dorr C bone combined with severe osteoporosis is an important challenge in primary hip arthroplasty. In this study, we assessed the effects of short metaphyseal fitting cementless stems on preformatted primary total hip arthroplasties in young adult osteoporotic patients with this femoral presentation. Methods A total of 42 hip arthroplasties were performed in 35 young patients (range 20 to 36 years) using a short Tri-lock bone preservation metaphyseal-fitting cementless femoral component between 2012 and 2017. The mean age at surgery of the 27 male (33 hips) and 8 female (9 hips) patients was 27.5 years (range 20.3 to 35.8 years). The mean body mass index (BMI) was 20.2 kg/m2 (range, 16.8–23.2 kg/m2). According to Dorr’s criteria, all 42 femora were classified as type C bone and all femurs suffered from severe osteoporosis (Singh index ≤ 3). Results The mean follow-up period was 5.5 years (range 3.0 to 8.0 years). The clinical and functional results improved for the Harris hip score, WOMAC, and UCLA activity scores. The Harris Hip score improved from 48.0 ± 8.0 (range 38.0 to 61.0) preoperatively to 87.0 ± 9.0 (range 77.0 to 92.0) at 12 months after surgery and 91.0 ± 8.0 (range 85.0 to 98.0) at final follow-up. The preoperative UCLA activity score was 3.0 ± 0.5 points (range, 1.0–4.0 points), which significantly improved to 7.5 ± 0.7 points (range 6.0 to 8.0 points) at the final follow-up. No patient exhibited thigh pain at the final follow-up. The mean stem-to-canal fill percentages were 97% ± 2.1% (anteroposterior view at midstem). For stem alignment, 40 hips (95.2%) of the femoral stem were positioned neutrally to 3° of varus with reference to the femoral shaft axis. The remaining two were positioned at 4° varus to 4° valgus. Radiographic evaluation showed good osteointegration of the implants in follow-up. Conclusions Based on the tapered-wedge design and proximal porous coating, the shortened tapered conventional stem can achieve reliable stability through neck filling and metaphyseal fixation, which does not depend on the isthmus hoop stress. This stem was suitable in severe osteoporotic patients with type C bones in young adults who presented with a correspondingly straightened femoral canal with a wide isthmus and thin cortex.
