ABSTRACT
Aims: The primary aim of this study was to report the radiological outcomes of patients with a dorsally displaced distal radius fracture who were randomized to a moulded cast or surgical fixation with wires following manipulation and closed reduction of their fracture. The secondary aim was to correlate radiological outcomes with patient-reported outcome measures (PROMs) in the year following injury. Methods: Participants were recruited as part of DRAFFT2, a UK multicentre clinical trial. Participants were aged 16 years or over with a dorsally displaced distal radius fracture, and were eligible for the trial if they needed a manipulation of their fracture, as recommended by their treating surgeon. Participants were randomly allocated on a 1:1 ratio to moulded cast or Kirschner wires after manipulation of the fracture in the operating theatre. Standard posteroanterior and lateral radiographs were performed in the radiology department of participating centres at the time of the patient's initial assessment in the emergency department and six weeks postoperatively. Intraoperative fluoroscopic images taken at the time of fracture reduction were also assessed. Results: Patients treated with surgical fixation with wires had less dorsal angulation of the radius versus those treated in a moulded cast at six weeks after manipulation of the fracture; the mean difference of -4.13° was statistically significant (95% confidence interval 5.82 to -2.45). There was no evidence of a difference in radial shortening. However, there was no correlation between these radiological measurements and PROMs at any timepoint in the 12 months post-injury. Conclusion: For patients with a dorsally displaced distal radius fracture treated with a closed manipulation, surgical fixation with wires leads to less dorsal angulation on radiographs at six weeks compared with patients treated in a moulded plaster cast alone. However, the difference in dorsal angulation was small and did not correlate with patient-reported pain and function.
ABSTRACT
BACKGROUND: To determine whether there is any difference in graft rerupture rates and clinical outcomes between cases having vancomycin graft presoaking vs. no vancomycin presoaking in anterior cruciate ligament (ACL) reconstruction (ACLR). METHODS: Systematic review and meta-analysis. PubMed, Embase, CINAHL, and Cochrane CENTRAL were searched. Full published studies reporting on the relation between vancomycin graft presoaking and rates of graft rerupture and/or clinical outcomes in ACLR surgery vs. no vancomycin graft presoaking were included. Data extraction and quality appraisal were performed. Meta-analysis was conducted using a random effects model. The study's protocol was prospectively registered with PROSPERO (CRD42021290608). RESULTS: The literature search identified 907 records. After removing duplicates and those not meeting inclusion criteria, 8 studies were included. Meta-analysis showed that the estimated risk of hamstring graft rerupture was lower in cases presoaked with vancomycin vs. those having no presoaking (3.2% vs. 6.2% rerupture rate, risk ratio [RR] = 0.507, 95% CI, 0.39-0.737, p < 0.001). Similarly, the estimated risk of graft rerupture was lower in cases presoaked with vancomycin vs. those having no presoaking when the analysis included various ACL graft types (2.7% vs. 3.9% rerupture rate, RR = 0.557, 95% confidence interval [CI], 0.403-0.771, p < 0.001). Meta-analysis also showed that vancomycin graft presoaking was associated with similar International Knee Documentation Committee scores as compared with no presoaking when looking at hamstring grafts (estimated mean difference 0.112, 95% CI, -2.359 to 2.582, p = 0.929) or when considering various graft types (estimated mean difference 0.933, 95% CI, -0.140 to 2.006, p = 0.088). CONCLUSION: Vancomycin graft presoaking is a safe practice and does not compromise ACL graft rerupture rates or clinical outcomes. LEVEL OF EVIDENCE: Level IV.

The aim of this retrospective study was to assess the relation between carpal malalignment correction and radiological union rates in surgery for scaphoid nonunions. A total of 59 scaphoid waist fracture nonunions treated with open reduction and palmar tricortical autograft were divided according to their pre- and postoperative scapholunate (SL) and radiolunate (RL) angles. We found that carpal malalignment failed to correct in 32 of 59 (54.2%) patients despite meticulous surgical technique and placement of an appropriately sized wedge-shaped graft. In total, 43 (72.9%) fractures united at a mean of 4.47 months (range 3-11). Of the 27 fractures with postoperative SL and RL angles within the normal range, 21 united, whereas 22 of the 32 remaining fractures that failed to achieve postoperative angles within the normal range went on to union. The postoperative SL and RL angles were not related to union. Our findings suggest that in scaphoid fracture nonunion surgery, carpal malalignment may not be corrected in a substantial proportion of patients, but such correction may not be essential for bony union. Our findings also show that there is no marked collapse of the scaphoid graft in the early postoperative period. LEVEL OF EVIDENCE: IV.
ABSTRACT
Aims: Aseptic loosening is the most common cause of failure following cemented total knee arthroplasty (TKA), and has been linked to poor cementation technique. We aimed to develop a consensus on the optimal technique for component cementation in TKA. Methods: A UK-based, three-round, online modified Delphi Expert Consensus Study was completed focusing on cementation technique in TKA. Experts were identified as having a minimum of five years' consultant experience in the NHS and fulfilling any one of the following criteria: a 'high volume' knee arthroplasty practice (> 150 TKAs per annum) as identified from the National joint Registry of England, Wales, Northern Ireland and the Isle of Man; a senior author of at least five peer reviewed articles related to TKA in the previous five years; a surgeon who is named trainer for a post-certificate of comletion of training fellowship in TKA. Results: In total, 81 experts (round 1) and 80 experts (round 2 and 3) completed the Delphi Study. Four domains with a total of 24 statements were identified. 100% consensus was reached within the cement preparation, pressurization, and cement curing domains. 90% consensus was reached within the cement application domain. Consensus was not reached with only one statement regarding the handling of cement during initial application to the tibial and/or femoral bone surfaces. Conclusion: The Cementing Techniques In Knee Surgery (CeTIKS) Delphi consensus study presents comprehensive recommendations on the optimal technique for component cementing in TKA. Expert opinion has a place in the hierarchy of evidence and, until better evidence is available these recommendations should be considered when cementing a TKA.
ABSTRACT
Identifying risk factors for fracture occurrence in breast cancer (BC) skeletal metastases (SM) may guide the management of such bone deposits. There is sparse evidence regarding receptor status in SM and their relationship to fracture occurrence. Our study aimed to determine the relationship between estrogen (ER), progesterone (PR) and HER2 receptor status and Ki-67 index and fracture occurrence in SM of BC. Exactly 152 samples of SM of BC obtained from individual patients were evaluated. The status of the aforementioned receptors and Ki67 index were determined in SMs samples. Their expression was compared between SM that did and did not develop a fracture. Ninety-one cases sustained a pathological fracture at the SM site, and 61 did not. Patients who sustained a pathological fracture had a higher rate of PR positivity at their SMs as compared to those with no fracture. There was no significant difference between the two groups concerning ER, HER2+ or Ki67 status. SMs secondary to BC with a fracture are more likely to be PR positive than those with no fracture. Determining the receptor status in SMs may identify high-risk groups for fracture occurrence, and determining the PR status may also guide surgical and hormonal therapy.

Aims: Loosening of components after total knee arthroplasty (TKA) can be associated with the development of radiolucent lines (RLLs). The aim of this study was to assess the rate of formation of RLLs in the cemented original design of the ATTUNE TKA and their relationship to loosening. Methods: A systematic search was undertaken using the Cochrane methodology in three online databases: MEDLINE, Embase, and CINAHL. Studies were screened against predetermined criteria, and data were extracted. Available National Joint Registries in the Network of Orthopaedic Registries of Europe were also screened. A random effects model meta-analysis was undertaken. Results: Of 263 studies, 12 were included with a total of 3,861 TKAs. Meta-analysis of ten studies showed high rates of overall tibial or femoral RLLs for the cemented original design of the ATTUNE TKA. The overall rate was 21.4% (95% confidence interval (CI) 12.7% to 33.7%) for all types of design but was higher for certain subgroups: 27.4% (95% CI 13.4% to 47.9%) for the cruciate-retaining type, and 29.9% (95% CI 15.6% to 49.6%) for the fixed-bearing type. Meta-analysis of five studies comparing the ATTUNE TKA with other implants showed a significantly higher risk of overall tibial or femoral RLLs (odds ratio (OR) 2.841 (95% CI 1.219 to 6.623); p = 0.016) for the ATTUNE. The rates of loosening or revision for loosening were lower, at 1.2% and 0.9% respectively, but the rates varied from 0% to 16.3%. The registry data did not report specifically on the original ATTUNE TKA or on revision due to loosening, but 'all-cause' five-year revision rates for the cemented ATTUNE varied from 2.6% to 5.9%. Conclusion: The original cemented ATTUNE TKA has high rates of RLLs, but their clinical significance is uncertain given the overall low associated rates of loosening and revision. However, in view of the high rates of RLLs and the variation in the rates of loosening and revision between studies and registries, close surveillance of patients who have undergone TKA with the original ATTUNE system is recommended.

Introduction: Radial head arthroplasty (RHA) is used for the management of unstable or unreconstructable injuries of the radial head. Our aim was to investigate clinical and radiographic outcomes in patients treated with the Acumed anatomic radial head press-fit system for trauma. Methods: Clinical and radiographic assessment of RHAs undertaken for trauma with minimum 2-year follow-up. Results: 16 consecutive patients, mean age 53 (21-82) and 66 month ± 27 (26-122) clinical follow-up were included. There were marked radiographic changes with 11/16 showing periprosthetic lucent lines and 13/16 showing subcollar osteolysis. Radiographic changes occurred early post-surgery. Stem loosening was associated with larger cantilever quotients (0.47 vs 0.38, p = 0.004). Overall survivability was 81.2%, with 3 RHAs removed. Clinical outcomes for the retained RHAs were acceptable with mean flexion 134°, extension deficit of 10°, pronation of 82°, and supination of 73°. Mean VAS scores were 8.5 ± 14.4, QuickDASH 13.8 ± 18.9, Mayo Elbow Performance Scores were 91.5 ± 12.5 with no poor scores. Conclusion: Mid-term clinical functional outcomes following the Acumed anatomic RHA are acceptable in most cases. However, in view of the extensive periprosthetic lucencies and surgical removal due to loosening, patients should be cautioned when consented for implantation of the prosthesis, especially if a large collar is anticipated.
ABSTRACT
Frozen shoulder is a common, painful condition that results in impairment of function. Corticosteroid injections are commonly used for frozen shoulder and can be given as glenohumeral joint (GHJ) injection or suprascapular nerve block (SSNB). Both injection types have been shown to significantly improve shoulder pain and range of motion. It is not currently known which is superior in terms of relieving patients' symptoms. This is the protocol for a randomized clinical trial to investigate the clinical effectiveness of corticosteroid injection given as either a GHJ injection or SSNB. The Therapeutic Injections For Frozen Shoulder (TIFFS) study is a single centre, parallel, two-arm, randomized clinical trial. Participants will be allocated on a 1:1 basis to either a GHJ corticosteroid injection or SSNB. Participants in both trial arms will then receive physiotherapy as normal for frozen shoulder. The primary analysis will compare the Oxford Shoulder Score (OSS) at three months after injection. Secondary outcomes include OSS at six and 12 months, range of shoulder movement at three months, and Numeric Pain Rating Scale, abbreviated Disabilities of Arm, Shoulder and Hand score, and EuroQol five-level five-dimension health index at three months, six months, and one year after injection. A minimum of 40 patients will be recruited to obtain 80% power to detect a minimally important difference of ten points on the OSS between the groups at three months after injection. The study is registered under ClinicalTrials.gov with the identifier NCT04965376. The results of this trial will demonstrate if there is a difference in shoulder pain and function after GHJ injection or SSNB in patients with frozen shoulder. This will help provide effective treatment to patients with frozen shoulder.
ABSTRACT
Objective: To assess the effect of PRP on knee articular cartilage content (thickness/volume) and examine the correlation between cartilage changes and clinical outcomes in patients with knee OA. Method: A systematic literature search was performed using the Cochrane methodology in four online databases. Studies were included if they reported on cartilage content with cross-sectional imaging pre- and post-injection. A random-effects model meta-analysis was performed. Correlation with clinical outcomes was evaluated. Results: 14 studies (n â= â1099 patients) from 1452 records met the inclusion criteria: seven RCTs (n â= â688), one prospective (n â= â50), one retrospective (n â= â68), and four case-series (n â= â224). The PRP preparation process and treatment protocol varied widely (follow-up 6-12 months). In meta-analysis, PRP treatment was not associated with a significant increase in cartilage thickness (4 studies, n â= â187, standardized mean difference: Hedges g: 0.079; 95%CI: 0.358 - 0.516; p â= â0.723). Meta-analysis of 3 RCTs (n â= â112) showed no significant difference in the change of overall knee cartilage content with PRP injections compared with no PRP (Hedges' g: 0.217; 95%CI: 0.177 - 0.611; P â= â0.281). Conclusion: The current literature does not support the PRP as chondrogenic in treatment of knee OA. However, there is substantial heterogeneity in the evaluated studies which limits the robustness of any conclusion. An adequately powered RCT, with a standardized PRP regime and standardized high-resolution MRI is needed to definitely define any effect of PRP on knee cartilage content and its relation to clinical outcomes. Until such high-quality evidence becomes available, we recommend that PRP is not administered with the intention of promoting chondrogenesis.
ABSTRACT
BACKGROUND: The impact of concurrent upper limb and fragility hip fractures has not been well defined. A greater understanding of this can guide decision making in the early peri-operative period and subsequent rehabilitation of such patients. AIMS: To identify if patients with concurrent upper limb and fragility hip fractures have different outcomes and demographics than those with an isolated hip fracture. METHODS: A search of MEDLINE and EMBASE was performed to identify cohort and case-control studies, comparing concurrent hip and upper limb fractures with isolated hip fractures. Meta-analysis was conducted using RevMan 5.4. Subgroup analyses were performed for concurrent distal radius and concurrent proximal humerus fractures. RESULTS: 13 studies were included reporting on 196,916 patients with an isolated hip fracture and 13,373 with concurrent hip and upper limb fractures. Patients with concurrent upper limb fractures had a significantly longer length of hospital stay (mean difference: 3.97 days, 95% CI: 1.36, 6.57, P=0.003) as compared to those with isolated hip fractures. Patients with concurrent upper limb fractures were significantly more likely to be female (OR: 0.57, 95% CI: 0.46, 0.70, P<0.00001), reside at home pre-injury (OR: 0.6, 95% CI: 0.37, 0.96, P=0.03) and have no cognitive impairment (OR: 0.54, 95% CI: 0.35, 0.84, P=0.006). Patients with concurrent distal radius fractures had significantly lower 90-day mortality (OR: 0.70, 95% CI: 0.49, 0.99, P=0.04) and 1-year mortality (OR: 0.68, 95% CI: 0.51, 0.90, P=0.008). CONCLUSIONS: Concurrent fragility hip and upper limb fractures are associated with increased length of hospital stay. We recommend early, aggressive, individualised rehabilitation to help improve outcomes and early hospital discharge in this highly vulnerable patient group.

OBJECTIVE: To determine the value of obtaining additional preoperative imaging in patients with a traumatic hip fracture and a history of malignancy in whom plain radiographs show no lesion suspicious for metastases. DESIGN: Retrospective review. SETTING: Teaching NHS Trust in the United Kingdom, over an 8-year period treating 4421 hip fractures. PATIENTS/PARTICIPANTS: Three hundred sixty-seven patients with hip fracture and a history of malignancy at a site distant to the hip. Three hundred thirty patients had a history of trauma and no lesion on the plain radiograph suspicious for metastases. MAIN OUTCOMES MEASUREMENTS: Whether obtaining additional imaging preoperatively (MRI, CT, and bone scan) identified metastases or affected management. RESULTS: 32/330 patients had further preoperative imaging, none of which demonstrated a pathological fracture secondary to malignancy. On follow-up, 3/330 (0.9%) cases were found to have occult metastasis at the hip fracture site. All 3 had only plain radiographs before surgery. In 2, this was identified on histological examination of intraoperative samples, and in 1, radiologically as a metastatic metaphyseal lesion 18 months after a hemiarthroplasty. Only in the latter case, preoperative identification of hip metastasis could have altered surgical management. Patients undergoing further preoperative imaging waited significantly longer for surgery (35 ± 26 vs. 51 ± 26 hours, P = 0.0011). CONCLUSIONS: In the absence of a suspicious metastatic lesion on initial plain radiographs, further preoperative imaging is unlikely to identify a lesion that will affect management and confers significant delays to surgery. Sending intraoperative histological samples may help guide postoperative oncological management, but further work is needed to prove its utility. LEVEL OF EVIDENCE: Diagnostic Level IV.

A large Hill-Sachs lesion that engages the glenoid rim and predisposes to recurrent anterior instability confers a substantial management challenge. Arthroscopic remplissage, either in isolation or combined with anterior labral repair, gives the arthroscopic surgeon a tool to stabilize the shoulder without reverting to more extensive open procedures or bone block reconstructions. In arthroscopic remplissage, the posterior capsule and infraspinatus are sutured into the humeral defect to limit such engagement between the HilleSachs lesion and the glenoid rim. The double-pulley technique using 2 transtendon anchors makes arthroscopic remplissage technically simpler, and potentially more reproducible, than earlier techniques. As we refine remplissage techniques, we need to further explore issues such as the optimal distance between the 2 anchors (and hence the resultant tendon bridge) as this distance-along with the pliability of the tendon-potentially determines how much compression against the bone can be achieved. Furthermore, as remplissage techniques are proven to be effective in restoring shoulder stability and conferring successful clinical function, there is even more need for high-quality comparative studies to define their role versus that of more extensive open stabilization procedures. Mechanistic studies are also needed to define the fill-effect versus the possible check-rein and neuromuscular control activation components of remplissage.

OBJECTIVES: To undertake a systematic review and meta-analysis to determine the relationship between perioperative hypothermia and mortality after surgery for hip fracture. DATA SOURCES: A systematic literature search of Medline, EMBASE, CINAHL, and Cochrane CENTRAL databases was performed using the Cochrane methodology for systematic reviews with no publication year limit. Only studies available in the English language were included. STUDY SELECTION: Predetermined inclusion criteria were patients of any age with a hip fracture, exposure was their body temperature and outcome was mortality rate. Any comparative study design was eligible. DATA EXTRACTION: The quality of selected studies was assessed according to each study design with the Methodological Index for Non-Randomised Studies (MINORS) used for all the retrospective comparative studies. The GRADE approach was used to assess the quality of evidence. DATA SYNTHESIS: A meta-analysis was conducted using a random-effects model. RESULTS: The literature search identified 1016 records. After removing duplicates and those not meeting inclusion criteria, 3 studies measuring 30-day mortality were included. All included studies were carried out in the United Kingdom. The mortality rate was higher in the hypothermic groups as compared with the normothermic group in all the studies, with the difference being significant in 2 of the studies (P < 0.0001). The meta-analysis showed that low body temperature was associated with an increased mortality risk (estimated odds ratio: 2.660; 95% confidence interval: 1.948-3.632; P < 0.001) in patients undergoing surgery for hip fracture. CONCLUSIONS: This study shows that low body temperature in hip fracture patients is associated with an increased 30-day mortality risk in the United Kingdom. Randomized control trials are required to determine whether the association between perioperative hypothermia in hip fracture patients and mortality is causal. Nevertheless, based on this analysis, we urge the maintenance of normal body temperature in the perioperative period to be included in national hip fracture guidelines. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

The aim of this study was to determine if the type of reamer used in tibial tunnel creation during anterior cruciate ligament (ACL) reconstruction influences the dimensions of the tunnel's outer aperture. Tibial tunnels were created in tibial saw bones by reaming over a guidewire using an 8 mm acorn or fluted reamer in an antegrade manner. Reaming was aimed either in line with the guidewire, or with 10-degree inferior/superior deviation in relation to the wire. The shape and size of the outer aperture of the tibial tunnel were compared between the two reamers. When using the acorn reamer, a 10-degree deviation in relation to the guidewire resulted in minimal change in outer aperture length (mean 13.6 vs. 15.6 mm, p = 0.11) and width (11.6 vs. 11.1 mm, p = 0.51). However, when using the fluted reamer, although the aperture width showed no substantial change with reamer/guidewire deviation (11.4 vs. 11.2 mm, p = 0.71), the mean length almost doubled (14.7 vs. 28.1 mm, p = 0.002). The use of a fluted reamer when reaming the tibial tunnel creates a distal aperture which is inconsistently sized, larger, and of oblong shape compared with an acorn-shaped reamer. This should be taken in consideration when using a fluted reamer for creating the tibial tunnel in ACL reconstruction.

Anterior cruciate ligament (ACL) reconstruction, using an ipsilateral hamstring graft, may necessitate an alternative graft source if the obtained graft is insufficient with regards to length or diameter. The study aims to determine the rate of insufficient ipsilateral hamstring graft harvesting in primary ACL reconstruction. Retrospective review of 50 consecutive primary ACL reconstructions performed by a single surgeon in the United Kingdom. In 3 of 50 cases, there was insufficient ipsilateral hamstring graft harvesting and a contralateral hamstring graft was used. In two cases, this was due to premature division of the ipsilateral hamstring tendons (3/100 harvested tendons). In one case, an adequate length of semitendinosus was obtained, but its central portion was too thin. Retrospective review of preoperative magnetic resonance imaging identified the thin part of the tendon in the latter case. Insufficient ipsilateral hamstring graft harvesting is a recognized, yet unusual intraoperative complication in primary ACL reconstruction. Presurgical planning as to how to manage such complications is essential.

BACKGROUND: After anterior cruciate ligament (ACL) injury, the optimal timing of ACL reconstruction and the influence of this timing on chondral damage remain unclear. PURPOSE: To assess the effect of timing of ACL reconstruction on the presence of chondral injuries via a systematic review and meta-analysis. STUDY DESIGN: Systematic review and meta-analysis; Level of evidence, 4. METHODS: Two reviewers independently performed systematic literature searches of 5 online databases using the Cochrane methodology for systematic reviews. Eligibility criteria were any comparative study of patients aged >16 years that assessed the relationship between timing of primary ACL reconstruction surgery and rates of chondral injuries. Meta-analysis was conducted using a random-effects model. RESULTS: After screening, 14 studies (n = 3559 patients) out of 2363 titles met the inclusion criteria: 3 randomized controlled trials (n = 272), 3 prospective cohort studies (n = 398), and 8 retrospective cohort studies (n = 2889). In analysis of the studies, chondral injury rates were compared between ACL reconstructions performed before and after 3 time points: 3, 6, and 12 months after injury (eg, ≤3 vs >3 months). The rates of chondral injury increased with each time point. The increase was mostly due to low-grade injuries at 3 months (estimated odds ratio, 1.914; 95% CI, 1.242-2.949; P = .003), with the increase in high-grade injuries becoming predominant after 12 months (estimated odds ratio, 3.057; 95% CI, 1.460-6.40; P = .003). CONCLUSION: Our findings suggest that delaying ACL reconstruction surgery results in a higher rate of chondral injuries and the severity of these lesions worsens with time. These findings are comparable with those of our previously published study, which demonstrated a higher risk of meniscal tears associated with delayed ACL surgery. When ACL reconstruction is indicated, surgery ≤3 months after injury is associated with a lower risk of intra-articular damage. REGISTRATION: CRD42016032846 (PROSPERO).

BACKGROUND: Frozen shoulder is a common condition resulting in severe pain and restricted range of motion. An assessment of the effectiveness of interventions may provide an improved understanding of the development and management of frozen shoulder. METHODS: A literature search was conducted using Embase, the Cumulative Index of Nursing and Allied Health (CINAHL), the Cochrane Central Register of Controlled Trials (CENTRAL), and National Center for Biotechnology Information PubMed using relevant terms. Studies were included if they assessed the outcomes of interventions on the suprascapular nerve that aim to improve the symptoms of frozen shoulder. RESULTS: A database search returned 196 articles. After review, 9 articles met the inclusion criteria and were included in the analysis. Suprascapular nerve interventions (nerve block, pulsed radiofrequency lesioning) are associated with improvement in pain, motion, and function. Meta-analysis showed that pain (Hedges g, -3.084 [95% confidence interval (CI), -4.273 to -1.894]; p < 0.001) and range of motion (Hedges g, 2.204 [95% CI, 0.992 to 3.415]; p < 0.001) improved significantly following suprascapular nerve block (SSNB). CONCLUSIONS: SSNB is associated with significant improvements in shoulder pain and range of motion in patients with frozen shoulder. Further randomized controlled trials comparing SSNB with intra-articular injection and other nonoperative treatments are required to fully define its role in the management of frozen shoulder.

OBJECTIVES: To explore the experiences and perceptions of trial participants and healthcare professionals in the UK Frozen Shoulder Trial (UK FROST), a multicentre randomised controlled trial that compared manipulation under anaesthesia (MUA), arthroscopic capsular release (ACR) with a 12-week early structured physiotherapy programme (ESP) in people with unilateral frozen shoulder referred to secondary care. DESIGN: Nested qualitative study with semistructured interviews. We used constant comparison method to develop our themes. SETTING: This qualitative study was nested within the UK FROST. PARTICIPANTS: 44 trial participants (ESP: 14; MUA: 15; ACR: 15), and 8 surgeons and 8 physiotherapists who delivered the treatments in the trial. RESULTS: Trial participants found UK FROST treatments acceptable and satisfactory in terms of content, delivery and treatment benefits. Participants in all arms experienced improvements in pain, shoulder movements, and function. Participants said they would choose the same treatment that they received in the trial.Surgeons and physiotherapists felt that the content and delivery of UK FROST treatments was not significantly different to their routine practice except for the additional number of physiotherapy sessions offered in the trial. They had mixed feelings about the effectiveness of UK FROST treatments. Both stressed the value of including hydrodilatation as a comparator of other treatment options. Physiotherapists raised concerns about the capacity to deliver the number of UK FROST physiotherapy sessions in routine clinical settings.Shared perceptions of trial participants, surgeons and physiotherapists were: (1) Pain relief and return of shoulder movements and function are important outcomes and (2) Adherence to exercises leads to better outcomes. CONCLUSION: In general, our findings indicated that trial participants, and surgeons and physiotherapists who delivered the treatments had positive experiences and perceptions in the UK FROST. Early qualitative investigations to explore the feasibility of delivering treatments in real-world settings are suggested in future trials in the frozen shoulder.

BACKGROUND: Determining trends in managing humeral shaft fractures may help identify variation in practice which might benefit design of clinical guidance. We aimed to determine the practice of members of the British Elbow and Shoulder Society (BESS) in managing humeral shaft fractures. METHODS AND MATERIALS: An electronic survey was sent to members of BESS. Questions related to preferred surgical and nonsurgical approaches for management of humeral shaft fractures. This was divided into management of proximal, middle and distal third diaphyseal fractures. RESULTS: 91 fully completed responses were analysed. Nonsurgical management was preferred by 90.1% (n=82) for middle-third and 80.2 % (n=73) for proximal third fractures, however 52.7% (n=48) favoured surgical treatment for distal third fractures. CONCLUSIONS: 1. The management preference for humeral shaft fractures amongst surgeons is highly variable. 2. This may be partly attributed to the sparsity of high-quality evidence. 3. Well-designed randomised trials or pro-spective cohort studies may help further guide management of these injuries.

BACKGROUND: Frozen shoulder is a common, poorly understood condition affecting the shoulder joint, with poor long-term outcomes in some in relation to pain and mobility. Understanding the pathophysiology of frozen shoulder at a cellular level and a molecular level may help in the development of novel treatments. The aim of this study was to perform a systematic review of studies examining the cellular, molecular, and metabolic findings in frozen shoulder. METHODS: A literature search was conducted using Embase, CINAHL (Cumulative Index of Nursing and Allied Health Literature), and PubMed using relevant terms. Studies were included if they assessed cellular, molecular, or metabolic alterations in tissue or blood samples of patients with frozen shoulder. RESULTS: Of 4,794 studies identified, 25 were included for analysis. Histological findings included nonspecific chronic inflammation and the proliferation of fibroblasts, adipocytes, and blood vessels. Molecular studies showed increased pro-inflammatory mediators, reduced matrix metalloproteinases (MMPs), and increased activity of factors promoting fibroblast activation and nerve growth. Metabolic alterations included an increase in blood lipids. CONCLUSIONS: Frozen shoulder is thought to occur after a primary insult to the shoulder triggers a complex cascade and upregulation of growth factors and cytokines with an increased turnover of the extracellular matrix, activation of myofibroblasts with deposition of collagen, and reduced matrix degradation. The presence of a background pro-inflammatory state (e.g., patients with diabetes or hyperlipidemia) may exacerbate these abnormalities. Further work assessing patients in early stages of the disease and comparing the inflammatory or fibrogenic characteristics of the shoulder capsule with those of the other joints may help to determine the initiating factors and to explain the predisposition of the shoulder to stiffness. CLINICAL RELEVANCE: Our findings may form the basis for identifying new targets for the clinical management of frozen shoulder.
