Aims. We aimed to address the question on whether there is a place for shoulder stabilization surgery in patients who had voluntary posterior instability starting in childhood and adolescence, and later becoming involuntary and uncontrollable. Methods. Consecutive patients who had an operation for recurrent posterior instability before the age of 18 years were studied retrospectively. All patients had failed conservative treatment for at least six months prior to surgery; and no patients had
The burden of hospital length of stay (LOS) and readmissions for total hip arthroplasty (THA) patients has resulted in great scrutiny. The purpose of this study was to determine our patients' LOS and hospital readmissions over the past 7 years. The second purpose was to determine what comorbidities affected the LOS and readmissions of 1440 THA patients. 1440 THA patients were retrospectively reviewed. The group included 622 males, 818 females. The average age of the cohort was 60 years (12 to 94 years). Ninety-day hospital readmissions were measured for the patients. Fisher's exact test, independent Sample t-test and Spearman correlation coefficients were used to determine associations of patient characteristics and comorbidities with readmission status and LOS with comorbidity status. The LOS decreased over the time of the study (p=0.02), however; readmissions remained constant at approximately 6% (p=0.73). The mean LOS for patients not readmitted was significantly shorter than for those readmitted (3.2 vs. 4.4 days; p=0.0003). Comorbidities associated with a longer hospital stay included diabetes (p=0.0052), hypertension (p=0.04), coronary artery disease (p=0.0034), congestive heart failure (p=0.0012), peripheral vascular disease (p=0.015), chronic obstructive pulmonary disease (p=0.016), renal disease (p=0.009), and
Aims. This paper aims to review the evidence for patient-related factors associated with less favourable outcomes following hip arthroscopy. Methods. Literature reporting on preoperative patient-related risk factors and outcomes following hip arthroscopy were systematically identified from a computer-assisted literature search of Pubmed (Medline), Embase, and Cochrane Library using Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines and a scoping review. Results. Assessment of these texts yielded 101 final articles involving 90,315 hips for qualitative analysis. The most frequently reported risk factor related to a less favourable outcome after hip arthroscopy was older age and preoperative osteoarthritis of the hip. This was followed by female sex and patients who have low preoperative clinical scores, severe hip dysplasia, altered hip morphology (excess acetabular retroversion or excess femoral anteversion or retroversion), or a large cam deformity. Patients receiving workers’ compensation or with rheumatoid arthritis were also more likely to have a less favourable outcome after hip arthroscopy. There is evidence that obesity, smoking, drinking alcohol, and a history of
Given the high prevalence of psychiatric illness in the total joint arthroplasty (TJA) population, relatively little is known about how these two conditions affect each other. Therefore, the purpose of this study is to evaluate the role of major psychiatric illness on patient specific outcomes after TJA. We hypothesize that patients with major psychiatric illnesses will report inferior outcomes and have more complications after TJA compared to those without any psychiatric illness. We matched and compared two cohorts of patients undergoing TJA from a prospectively collected database registry, which included those with and without a major

Patients with above knee amputation (AKA) often experience poor socket fit exacerbated by minor weight changes, sweating, and skin problems. A transcutaneous, press-fit distal femoral intra-medullary device was designed in 1999, such that the distal external aspect serves as a hard point for AKA prosthesis attachment. The implant is placed in a retrograde fashion, followed 6-8 weeks later by stomatisation and connected via direct extention to an AKA prosthesis. Thirty-seven patients with 39 limbs (30 males, 7 females) underwent two-stage prosthesis implantation with the Endo-Exo Femurprosthesis (EEFP) in Germany between 1999 and January 2008. Their indications for surgery were persistent AKA prosthesis socket difficulties with absence of major comorbid physical or
The safety and efficacy of bone-healing enhancement with Bone Morphogenetic Protein-7 (BMP) has been studied in the clinical setting of persistent post-traumatic and post-partum pelvic instability. Prospective collection and analysis of all cases with pelvic ring instability after trauma or childbirth, treated with reconstruction and local application of BMP-7. Patient demographics, hospitalisation, operative interventions before and after the BMP-7 grafting, and follow-up data were recorded and evaluated. The median follow-up period was 1 year (range 12 to 18 months). Over a two-year period (March 2005 – January 2007) nine patients (8 females) with median age of 39 years (31–62) were operated for persistent pelvic instability and pain. The mean number of previous operations was 1,6 procedures. Reconstruction of the pelvic ring included 4 cases of post-partum pubic symphysis instability, 2 traumatic non-unions of pubis symphysis and 3 sacroiliatis (1-septic and 2-aseptic). Reconstruction included double plating of pubis symphysis (4-cases), external pelvic fixation (2-cases), sacroiliac screw fixation (1-case) and anterior sacroiliac plating (2-cases). In 4 cases BMP-7 was used alone; in 5 it was used together with iliac crest autograft. All patients were mobilizing with a wheelchair for a period of 8 weeks (6–12) before progressing to full weight bearing. Clinical and radiological union occurred in 8/9 cases at a median time of 14 weeks (range 12–20). One female patient with post-partum pubic symphysis instability and a chronic
Purpose: To understand the epidemiology and risk factors of an osteoporotic hip fracture in a non-elderly patient. Methods: Retrospective study covering the period 1999–2004, assessing individual and family history, fracture type, hospital stay, time until surgery, type of treatment and possible study or treatment of bone fragility. Results: 38 cases. 23 patients (60.5%) presented some risk factor related to osteoporosis: enolism 7, liver pathology 3, neuromuscular disease 13, steroid treatment 4 and anticonvulsant 3. Seven patients (18.4%) presented some type of

The aims of this study were to validate the Forgotten Joint Score-12 (FJS-12) in the postoperative evaluation of periacetabular osteotomy (PAO), identify factors associated with joint awareness after PAO, and determine the FJS-12 threshold for patient-acceptable symptom state (PASS). Data from 686 patients (882 hips) with hip dysplasia who underwent transposition osteotomy of the acetabulum, a type of PAO, between 1998 and 2019 were reviewed. After screening the study included 442 patients (582 hips; response rate, 78%). Patients who completed a study questionnaire consisting of the visual analogue scale (VAS) for pain and satisfaction, FJS-12, and Hip disability and Osteoarthritis Outcome Score (HOOS) were included. The ceiling effects, internal consistency, convergent validity, and PASS thresholds of FJS-12 were investigated.Aims

The aim of this study was to compare the early postoperative mortality and morbidity in older patients with a fracture of the femoral neck, between those who underwent total hip arthroplasty (THA) and those who underwent hemiarthroplasty. This nationwide, retrospective cohort study used data from the Japanese Diagnosis Procedure Combination database. We included older patients (aged ≥ 60 years) who underwent THA or hemiarthroplasty after a femoral neck fracture, between July 2010 and March 2022. A total of 165,123 patients were included. The THA group was younger (mean age 72.6 (SD 8.0) vs 80.7 years (SD 8.1)) and had fewer comorbidities than the hemiarthroplasty group. Patients with dementia or malignancy were excluded because they seldom undergo THA. The primary outcome measures were mortality and complications while in hospital, and secondary outcomes were readmission and reoperation within one and two years after discharge, and the costs of hospitalization. We conducted an instrumental variable analysis (IVA) using differential distance as a variable.Aims

Purpose: The double mobility of the G. Bousquet cup—head-polyethylene,polyethylene metal cup—considerably reduces the risk of total hip arthroplasty displacement. Material and methods: We observed seven cases of “intra-prosthetic” displacement in patients with this type of cup. Progressive wear of the polyethylene retention ring allowed displacement of the femoral head. These displacements occurred in six patients (one bilateral case) aged 43–58 years, on the average ten years after the implantation (range 3.5 – 15 years). All patients underwent revision. Results: The polyethylene retention ring was worn in all cases allowing the femoral head to escape. Revision surgery was performed very early in six hips to change the modular base and the polyethylene ring and re-establish retaining capacity. A satisfactory result was achieved in all cases. One patient required revision five years later to change the prosthesis subsequent to haematogenous infection. Another patient underwent a late revision to change the modular base and the entire cup of a press fit implant. This hip was in excellent condition but revision was decided on because of four dislocations. Discussion: Intra-prosthetic displacement of the polyethylene head of a double-mobility cup is exceptional in our experience. Wear of the retention ring is favoured by different elements: 1) direct phenomena: neck and head diameter causing early contact between the neck and the cup; 2) indirect phenomena: factors limiting the mobility of the polyethylene metal cup couple (fibrosis, repeated interventions, ossification). In our experience, intra-prosthetic displacement occurs more readily in patients with favouring conditions (alcoholism, muscle deficiency,
Repeated lumbar spine surgery has been associated with inferior clinical outcomes. This study aimed to examine and quantify the impact of this association in a national clinical register cohort. This is a population-based study from the Norwegian Registry for Spine surgery (NORspine). We included 26,723 consecutive cases operated for lumbar spinal stenosis or lumbar disc herniation from January 2007 to December 2018. The primary outcome was the Oswestry Disability Index (ODI), presented as the proportions reaching a patient-acceptable symptom state (PASS; defined as an ODI raw score ≤ 22) and ODI raw and change scores at 12-month follow-up. Secondary outcomes were the Global Perceived Effect scale, the numerical rating scale for pain, the EuroQoL five-dimensions health questionnaire, occurrence of perioperative complications and wound infections, and working capability. Binary logistic regression analysis was conducted to examine how the number of previous operations influenced the odds of not reaching a PASS.Aims

The use of multimodal non-opioid analgesia in hip fractures, specifically acetaminophen combined with non-steroidal anti-inflammatory drugs (NSAIDs), has been increasing. However, the effectiveness and safety of this approach remain unclear. This study aimed to compare postoperative outcomes among patients with hip fractures who preoperatively received either acetaminophen combined with NSAIDs, NSAIDs alone, or acetaminophen alone. This nationwide retrospective cohort study used data from the Diagnosis Procedure Combination database. We included patients aged ≥ 18 years who underwent surgery for hip fractures and received acetaminophen combined with NSAIDs (combination group), NSAIDs alone (NSAIDs group), or acetaminophen alone (acetaminophen group) preoperatively, between April 2010 and March 2022. Primary outcomes were in-hospital mortality and complications. Secondary outcomes were opioid use postoperatively; readmission within 90 days, one year, and two years; and total hospitalization costs. We used propensity score overlap weighting models, with the acetaminophen group as the reference group.Aims
