Aims. The aim of this study was to investigate mortality and risk of intraoperative medical complications depending on delay to hip fracture surgery by using data from the Norwegian Hip Fracture Register (NHFR) and the Norwegian Patient Registry (NPR). Patients and Methods. A total of 83 727 hip fractures were reported to the NHFR between 2008 and 2017. Pathological fractures, unspecified type of fractures or treatment, patients less than 50 years of age, unknown delay to surgery, and delays to surgery of greater than four days were excluded. We studied total delay (fracture to surgery, n = 38 754) and hospital delay (admission to surgery, n = 73 557). Cox regression analyses were performed to calculate relative risks (RRs) adjusted for sex, age, American Society of Anesthesiologists (ASA) classification, type of surgery, and type of fracture. Odds ratio (OR) was calculated for intraoperative medical complications. We compared delays of 12 hours or less, 13 to 24 hours, 25 to 36 hours, 37 to 48 hours, and more than 48 hours. Results. Mortality remained unchanged when total delay was less than 48 hours. Total delay exceeding 48 hours was associated with increased three-day mortality (RR 1.69, 95% confidence interval (CI) 1.23 to 2.34; p = 0.001) and one-year mortality (RR 1.06, 95% CI 1.04 to 1.22; p = 0.003). More intraoperative medical complications were reported when hospital delay exceeded 24 hours. Conclusion. Hospitals should operate on patients within 48 hours after fracture to reduce mortality and intraoperative complications. Cite this article: Bone Joint J 2019;101-B:1129–1137

Purpose. Surgical correction of upper limb deformities in severe osteogenesis imperfecta (OI) is technically difficult and less absolving, hence we aimed to analyse the surgical complications of rodding the humeri in severe OI. Methods and results. Retrospective analysis was carried out for consecutive humeral roddings for severe OI in last 3 years. Surgical technique for all humeri included retrograde telescopic nailing (female or both of FD or TST rods) with entry from olecranon fossa, exploration of radial nerve followed by osteotomies. Deformities were quantified and sub-classified as per level of deformity). Variables such as number of osteotomies, radiological union, intraoperative and postoperative complications, improvement in ROM and subjective patient satisfaction were recorded. Total 18 humeri in 12 patients with type III OI (except 1) with mean age of 8.9 years underwent nailing. All patients achieved radiological union at 6–10 weeks. Total 8 complications (44.4 %) were reported within mean 8.4 months follow up. Four segments (22.2 %) had intraoperative fractures at distal third of the humerus while negotiating the nail. Significantly higher intraoperative complications were encountered in humeri fixed with both components combined and upper third level deformities, deformities > 900 and more than 2 osteotomies. Other complications were prominent implant at upper end (2) with growth and one each of contralateral fracture and distal humeral varus. All patients reported improvement in ROM and functional status. Conclusion. Significant complications are associated with humeral nailing for severe OI. Quantification of the deformity with meticulous surgical planning and execution is advised. Despite these complications outcomes show benefits of the surgical treatment. Level of evidence.

Introduction. When translating the principle of intramedullary nailing for trochanteric femoral fractures to Asian patients, design modifications made to adjust for anatomic differences resulted in an PFNA Asia. The primary endpoint of this study was the rate of complications attributable to fracture fixation. Material and methods. A prospective multicenter case series was performed; 176 patients with a median age of 84 with unstable trochanteric fractures treated with a PFNA Asia were included and followed for one year postoperatively. Complications were reviewed by a complication review board (CRB). Intra- and postoperative fracture fixation complications are presented according to type and incidence proportions (risk). Results. The CRB identified a total of three intraoperative (1.7%) and 14 postoperative fracture fixation complications (8%). Intraoperative complications included a problem with distal locking (1) and poor intraoperative reduction (2). Postoperative fracture fixation problems included significant neck shortening (8), implant breakage (3), cut-outs (2), and one severe loss of reduction. Outcome for most complications was adequate and none were classified as definitely related to the implant design but rather to surgical technique. Discussion & Conclusion. The adaptation of size and geometry to Asian patients leads to a low incidence of intra- and postoperative fracture fixation complications comparable to other studies

Objective. High grade hallux rigidus is a forefoot deformity characterized by a limitation of dorsiflexion of the first toe associated with pain, and severe damage of the first metatarsophalangeal joint. Most authors recommended resection arthroplasty or arthrodesis of the first metatarsophalangeal joint. The aim of this study was to present the results of our series of 42 consecutive cases of severe hallux rigidus treated by resection of the first metatarsal head and implant of a poly D-L lactic (PDLLA) bioreabsorbable spacer to promote the interposition of fibrous tissue to preserve the range of motion of the joint. Material and methods. Forty-two feet in 27 patients affected by high grade hallux rigidus were included in the study. Surgical treatment consisted of resection of the first metatarsal head and positioning of a poly D-L lactic acid (PDLLA) bioreabsorbable implant. Post-operative care consisted in gauze bandage of the forefoot, and immediate weight-bearing with talus shoes for 3 weeks. All patients were clinically and radiographically evaluated preoperatively and checked at a mean 6 (5–7) year follow-up. Results. No intraoperative complication occurred. No sinus formation were observed. All implants resulted well tolerated by the patients. Mean AOFAS score was 42±14 preoperatively and 81±9 postoperatively. Mean preoperative metatarsophalangeal joint ROM was 27±17 degrees and mean postoperative metatarsophalangeal joint ROM was 75±8 degrees. Conclusions. First metatarsophalangeal joint arthroplasty using bioreabsorbable implant demonstrated to be an effective surgical option for treatment of high grade hallux rigidus, thank to its ability to promote fibrous tissue formation during its reabsorption

Introduction. A review of the literature showed a discrepancy between biomechanical and clinical studies on fracture fixation failure in patients with poor bone quality. The objective of the present study is to assess the influence of local bone status on complications after surgical treatment of proximal humerus fractures. Methods. A prospective cohort study was initiated in 2007. The inclusion criteria were closed displaced fractures of the proximal humerus, primary fracture treatment with a Philos plate, patients aged 50 to 90, normal pre-trauma function of both shoulders in accordance to age, and monotrauma. There was active follow-up for one year with radiological assessment at clinical centers from four countries. Bone quality at the proximal humerus was determined preoperatively for the contralateral side of the fracture by CT scan, and at the contralateral radius within six weeks post-surgery by DXA. The occurrence of complications was monitored up to one year post-surgery. Independent x-ray evaluation and final classification of all complications will be performed at the end by a study review board using anonymous data and x-rays. Preliminary Results. 157 patients, 127 female (79%) met the inclusion criteria. Their mean age at time of surgery is 69 (range 50–89). 119 patients (100%) attended the 1-year follow-up assessment, 64 (96%) the one at 3 months, and 148 (99%) the 6 week follow-up examination. According to the WHO criteria, 107 patients (71%) suffered from either osteopenia or osteoporosis, while 43 patients (29%) had a normal T-score. The overall reported complication rate was 39%. However, the number of intraoperative complications was 0.6%, bone/fracture complications 19.1%, implant complications 15.3%, and general complications 14.6%. Discussion. Fixation of proximal humerus fractures with Philos plates in elderly people with osteoporotic bone is associated with a high rate of fixation failure. Final results will be reported after x-rays, local BMD (CT- based) and complications assessment have been conducted

Objectives. Juxtafacet cysts of the spine can cause radicular pain, neurological symptoms and are often associated with spinal degeneration. The mainstay of treatment of juxtafacet cysts is surgical resection with laminotomy and resection of the cyst. Other methods, including epidural steroid and facet injections are mostly temporarily effective. The aim of this study is the sufficient decompression with reduced traumatization and destabilization with the full-endoscopic interlaminar and transforaminal technique. Methods. 60 patients with unilateral, single-level juxtafacet cysts were included in this study. 30 Patients (group 1) were operated in full-endoscopic technique (22 interlaminar, 8 trans-/extraforaminal) and 30 Patients (group 2) with conventional microscopic-assisted technique. The full-endoscopic operation was performed with 6.9-mm endoscopes with 4.1-mm intra-endoscopic working canal. The follow-up was 18 months. 27 (91%) patients were followed. Additionally to general parameters validated scores were used. Results. No intraoperative complications occurred. 2 patient in group 1 and 4 patients in group 2 showed transient dysaesthesia. The mean operation time in group 1 was 32 minutes, in group 2 56 minutes. There was no measurable blood loss in group 1, and a mean blood loss of 85 ml in group 2. The follow-up showed satisfactory subjective results in 53 patients. There were no significant differences between the two groups or within group 1 between the transforaminal and interlaminar technique in the clinical results. Group 1 showed significant advantages in different clinical, technical and economical parameters. The maximum time in hospital for group 1 patients was 3 days and 6 days in group 2. No recurrence of the cyst was found in the follow up. Conclusion. The full-endoscopic operation of lumbar facet cysts with full-endoscopic technique is an alternative to the conventional microscopic-assisted procedure for sufficient decompression of juxtafacet cyst. It enables selective procedure with direct visualization, sufficient decompression and less traumatization of the access pathway and the spinal canal structures

Purpose. Exeter stem was introduced to Japanese market at 1996. Since then, owing to its excellent clinical results, the number of the stem used has been increased year by year and more than 2000 stems have been implanted during the year 2009. The present study aims to prove its efficacy for Japanese patients by evaluating short term results of four major dedicated hip centers. Method. We present the short-term multi-center results of primary THA with Exeter stem combined with modern cementing technique in 881 patients (1000 hips). The average age of the patients at operation was 62.3years (ranging 23 to 89 years). Mean postoperative follow up period was 4.0 (ranging 2 to 9) years. Results. Intraoperative complications such as femoral fracture were observed in 6 hips. Postoperative cementing grade using Barrack's classification was judged as A for 735 hips, as B for 246 hips, and as C for 4 hips, respectively. Twenty-four patients died with unrelated disease and 52 patients were lost during follow-up period. Follow-up ratio was 94.8%. Thirty postoperative complications which include 9 infections, 14 dislocations, 5 deep vein thrombosis, and 2 sciatic nerve palsies were observed. Symptomatic pulmonary embolization or femoral fracture was not observed. Re-operations for infection and dislocation were performed for 8 and 6 hips, respectively. At the final follow-up, no radiolucent line at bone-cement interface was observed. Cortical hypertrophy was observed in 9.6% at Gruen zone 2 to 6. Kaplan-Meier survivorship analysis predicted a rate of survival at 5 years of 100% with radiolucent line at bone-cement interface of the femur as the endpoint, and of 98.8% when re-operation for any reason was used. Conclusion. The present study revealed excellent short-term result was obtained using Exeter stem combined with modern cementing technique for primary THAs in Japan

PURPOSE. To evaluate the late radiographic and functional complications occurring after treatment of reverse oblique trochanteric fractures with the proximal femoral nail. PATIENTS. This is a retrospective study which was conducted between October 2004 and October 2009. 55 patients with a reverse oblique trochanteric fracture were treated with the Gamma 3 nail. According to the AO classification, there were 36 type AIII-1, 8 AIII-2, 11 AIII-3 fractures. Closed reduction was achieved in all patients. The long gamma 3 nail was used in 34 fractures. The mean follow up was 18 months (range 9 to 32 months). The patients were evaluated clinically (Harris hip score) and radiographically. RESULTS. No intraoperative complications were recorded. During surgery, satisfactory reduction and acceptable nail insertion was assessed in all patients. No early postoperative technical failures were noticed. Complete union was achieved in 51 patients. The mean Harris hip score was 80.2. The results were excellent in 23 patients (41.8%), good in 19 (34.5%), fair in 9 (16.3%), and poor in 4 patients (7%). Late radiographic complications included secondary varus displacement due to cut-out of the proximal screw in three patients (5.4%), and calcification at the tip of the greater trochanter in nine patients (16%). Stress shielding as evidenced by the lack of cortical hypertrophy at the level of the tip of the implant were detected in 5 patients. Patients treated with a long gamma 3 nail achieved a statistically significant better result (p< 0.005). Three patients (5.5%) required a reconstructive procedure. CONCLUSION. Proximal femoral nailing provides stronger fixation of the proximal part in reverse oblique trochanteric fractures reducing mechanical complications. The implant choice, the accuracy of fracture reduction, and the correct placement of the nail are the key factors influencing the final outcome

Aim. to compare the medium term clinical and functional results of total hip arthroplasty after intertrochanteric osteotomy and primary total hip replacement. Material and methods. We compared 2 groups of patients: Group I-93 patients with total hip arthroplasty after intertrochanteric osteotomy and Group II-93 patients with primary total hip arthroplasty. The patients in the control group (Group II) were randomly chosen from the cases operated by the same surgical team using the same kind of implant like those in Group I. The osteotomies were of different types: medial displacement (27), varisation(19), valgisation (18), flexion(25), rotational (4). The demographic parameters were similar in the 2 groups. Technical intraoperative challenges were noted. The Harris Score was determined at 12 months and 3 years after surgery. Clinical and radiological check-ups were performed each year. The duration of each surgical procedure was recorded. Complications were noted during the entire follow-up. The mean follow-up was 77 months. Results. The average time interval between osteotomy and total hip replacement was 76 months. The average Harris Score (HHS) at 1 year after surgery was 88 in Group I and 93 in Group II. At 3 years, the average values of HHS were 85 in the first group and 92 in the second. After an average follow-up of 6 years, 6 patients in group I (6,45%) required revision arthroplasty, while in the second group this procedure was not necessary. The indication of revision was loosening of the femoral component in 4 cases and of both components in 2 cases. The duration of a total hip arthroplasty after an ostheotomy was almost two times longer than a primary total hip replacement. In most cases, the surgical procedure implicated removal of a blade plate or others fixation devices, reaming of the femur, osteotomies of the greater trochanter, reverse osteotomies of the intertrochanteric region and the use of special design (thin or curved) femoral stems. In group I, intraoperative complications included fractures of the femoral diaphysis, fractures of the greater trochanter, false passage for the femoral component and malposition of the femoral stem. Postoperative complications consist in dislocations, early loosening, heterotopical ossifications, wound sepsis, etc. Conclusions. Total hip arthroplasties after intertrochanteric osteotomies have clinical results a little bit inferior of those of primary total hip replacements, but the difference is not significative. The survival rate of prosthesis implanted after intertrochanteric osteotomies at 6 years is significantly inferior. Both the intraoperative and postoperative complications rates are far superior of those of the primary arthroplasties

Aims

Echocardiography is commonly used in hip fracture patients to evaluate perioperative cardiac risk. However, echocardiography that delays surgical repair may be harmful. The objective of this study was to compare surgical wait times, mortality, length of stay (LOS), and healthcare costs for similar hip fracture patients evaluated with and without preoperative echocardiograms.
