Incorporating Cone-Beam CT Into the Diagnostic Algorithm for Suspected Radiocarpal Fractures: A New Standard of Care?

OBJECTIVE. The purpose of this study was to assess the result of adding cone-beam CT to the standard imaging algorithm for patients with suspected radiographically occult traumatic radiocarpal fractures. SUBJECTS AND METHODS. A prospective review was performed on all patients who had cone-beam CT investigation of acute wrist pain after normal initial radiographs. Patients with no identified fractures were clinically reassessed and referred for MRI if concern for a fracture persisted. RESULTS. In all, 117 patients were assessed; 50.4% had fractures identified with a total of 67 radiographically occult fractures. One fracture was identified on MRI that was not seen on cone-beam CT. Cone-beam CT had sensitivity of 98.3% (95% CI, 91.1-100%), specificity of 100% (95% CI, 93.7-100%), positive predictive value of 100%, and negative predictive value of 98.3% (95% CI, 89.1-100%). Accuracy was 99.1% (95% CI, 95.3-100%). CONCLUSION. Incorporating cone-beam CT into routine clinical practice as part of a standardized diagnostic algorithm yielded a 50% fracture detection rate in patients with negative wrist radiographs but ongoing clinical concern for radiocarpal fracture. Cone-beam CT provides more diagnostic information than radiographs at a lower radiation dose than conventional MDCT. Given the poor accuracy of radiographs for acute radiocarpal fractures and the high fracture prevalence in this cohort, we feel that cone-beam CT should be regarded as the new standard of care in the investigation of these patients.

Glenohumeral joint osteoarthritis is not associated with clavicle fractures in a large arthroplasty cohort.

Introduction: A recent study based on a large osteological collection reported an association between clavicle fractures and osteoarthritis of the glenohumeral joint. No clinical study has yet addressed this potential association. Other radiographic parameters such as the critical shoulder angle have been associated with the risk of glenohumeral joint osteoarthritis. The primary outcome of this study was to determine if there is an association between glenohumeral joint arthritis and clavicle fractures. The secondary outcome was to determine the association between critical shoulder angle and glenohumeral joint arthritis in our patient cohort. Methods: We retrospectively analysed 572 consecutive shoulder arthroplasty surgeries. Osteoarthritis was the indication for 343 shoulder arthroplasties. 229 shoulder arthroplasties were performed due to another diagnosis such as trauma or fracture, cuff arthropathy, or revision surgery. Three fellowship trained consultant shoulder surgeons assessed the pre- and post-operative radiographs of all patients. Results: A clavicle fracture was suspected in 5/343 (1.5 %) shoulder arthroplasties performed due to osteoarthritis and 5/229 (2.1 %) shoulder arthroplasties performed for another diagnosis. Interobserver variability was assessed using a Fisher Exact test and showed no significant relationship between osteoarthritis and a fracture of the clavicle (p = 0.531). Critical shoulder angle results correlated with the previously published literature regarding critical shoulder angle and osteoarthritis and rotator cuff arthropathy. Conclusion: Clavicle fractures were not associated with glenohumeral osteoarthritis in our patient cohort of shoulder arthroplasty patients. Critical shoulder angle results were consistent with published literature. Further research in the form of prospective long term studies are needed to establish if any association exists between clavicle fractures and osteoarthritis of the glenohumeral joint. Level of evidence: Level III. Retrospective analysis.

A physiotherapy triage service for orthopaedic upper limb service: an effective way to reduce clinic visits and identify patients for operative intervention.

INTRODUCTION: Waiting times for orthopaedic outpatient clinics are steadily increasing over the past number of years worldwide. Physiotherapy triage clinics are being utilised to improve access for patients with non-urgent or routine musculoskeletal disorders, to be seen in a timely manner in specialised out-patient clinics. Using these clinics, the aim is to ultimately stratify patients into appropriate management pathways. The aim of our study is to review the effectiveness of a physiotherapy triage clinic run by advanced practitioner physiotherapists (APP), who specialise in the review of upper limb referrals from primary care physicians. METHODS: For this study, a prospective, observational design was used. Patients were referred to the Department of Orthopaedic Surgery, Upper Limb Service at a national elective Orthopaedic Unit. The patients' referrals were reviewed and allocated to a physiotherapy triage pathway if deemed routine, non-urgent cases. After assessment in the APP clinic, the physiotherapist made recommendations and highlighted patients who required review or case discussion with an orthopaedic surgeon. The discharge rate and outcome of patients referred on for further interventions or operative procedures was followed over a 3-year period. The outcomes for the patients were reviewed, including whether patients who met an orthopaedic surgeon went on to have surgical intervention. RESULTS: During the study, 646 patients were reviewed in an upper limb APP physiotherapy triage clinic. Of those reviewed, only 201 patients required review by an orthopaedic surgeon. Of those, 56 patients were scheduled for an operative procedure. Within the 3-year period, 50 patients of those scheduled underwent the procedure. The most commonly performed procedure being an arthroscopic subacromial decompression with or without acromioplasty or rotator cuff repair. A total of 145 patients referred by the physiotherapist had a shoulder injection including subacromial and glenohumeral intra-articular injection. The initial discharge rate was 68%. CONCLUSIONS: There is a high initial discharge rate after initial assessment by APP triage clinics for upper limb musculoskeletal pathology. This is beneficial in alleviating waiting list pressures allowing only those patients in need of intervention to be placed on the ever expanding waiting lists to see orthopaedic surgeons. This study shows a high proportion of patients being offered surgical intervention after being referred by the APP. We conclude from this that the agreement between the physiotherapist's initial diagnosis and that of the consultant surgeon being similar in identifying patients who would benefit from operative intervention.

Outcome of subscapularis muscle release for shoulder contracture secondary to brachial plexus palsy at birth.

Children with unresolved brachial plexus palsy frequently develop a disabling internal rotation contracture of the shoulder. Several surgical options, including soft tissue procedures such as muscle releases and/or transfers, and bone operations such as humeral osteotomy are available to correct this deformity. This study describes the effect of subscapularis muscle release performed in isolation. Thirteen patients (5 boys, 8 girls) were reviewed at an average of 3.5 years after their surgery (range, 2-7 years). Their mean age at operation was 4.7 years (range, 1-8 years). Three children had C5-C6 palsies, 8 had C5-C7 palsies, and 2 had C5-C8 palsies. Postoperatively, patients presented significant gains in shoulder active lateral rotation (+49 degrees, from 5 to 54 degrees), active abduction (+30 degrees, from 63 to 93 degrees), active flexion (+46 degrees, from 98 to 144 degrees), and active extension (+23 degrees, from 7 to 30 degrees). Gains were also observed in passive range of motion, but of a lesser degree. Subscapularis muscle release is a procedure we found to have few significant complications and was highly effective in increasing active range of motion and restoring shoulder function.
