RESUMO

Background: The aim of this study is to compare the surgical and non-operative management of displaced radial head fractures via a network meta-analysis of randomised controlled trials (RCTs). Methods: RCTs comparing management of isolated, displaced radial head fractures in adults were included in our review and statistical analysis. A systematic review of electronic databases (Medline, Embase and Cochrane Library) were screened for comparative RCTs reporting on the management of displaced radial head fractures in August 2021. Two investigators independently reviewed studies for eligibility and an assessment of bias was performed for each study. A Bayesian network meta-analysis of the included RCTs was performed. Results: Five RCTs (326 patients) were included in our meta-analysis. Treatment methods included radial head arthroplasty (RHA), open reduction internal fixation (ORIF) with metal implants (ORIF-M), ORIF with biodegradable implants (ORIF-B) and non-operative management. In our network meta-analysis of 'good' or 'excellent' patient-reported outcome measures (PROMs), RHA was significantly favourable to ORIF-M (OR: 0.04, CrI: 0.0011, 0.87), ORIF-B (OR: 0.1 CrI: 0.00076, 6.37). Nonoperative treatment was not shown to be significantly worse than RHA (OR: 0.01 CrI: 2.5e-0.5, 3.61). Conclusions: This network meta-analysis shows that in displaced radial head fractures, RHA is associated with significantly superior functional PROMs than ORIF-M based on the evidence available. Nonoperative management has not been shown to be significantly worse. Level of Evidence: Level III (Therapeutic).

RESUMO

Background: Distal biceps rupture presents with an increasing incidence and evidence suggests that although a surgical repair is not mandatory, it results in superior functional outcomes when compared to non-operative management. As implant technology has advanced, several devices have been utilised and studied in managing this pathology. We present our single-centre experience with the use of the ToggleLoc Ziploop reattachment device, a knotless cortical button implant, using a single-incision technique. Methods: Retrospective series of 70 consecutive distal biceps tendon repairs, at a mean follow-up of 45.6 months after surgery, using a standardised single implant, single-incision technique, and post-operative rehabilitation programme. Results: There was one (1.4%) re-rupture in our patient cohort. The range of motion was complete in all patients except for one patient who had symptomatic heterotopic ossification, causing limitation in pronation. Complications were minor with the commonest being transient neuropraxia of the lateral cutaneous nerve of the forearm. The mean Oxford elbow score was 46.9 out of 48, and the patient global impression of change scale was 7 out of 7 in 77% of cases. Conclusion: Our data support this technique and implant combination when dealing with acute and chronic distal biceps tendon rupture.

RESUMO

BACKGROUND: We assessed distal humeral column preservation effects on clinical, radiographic and patient reported outcomes following distal humerus hemiarthroplasty for acute unreconstructable fractures. METHODS: Thirty-seven consecutive patients (mean age, 75; range, 29-93 years) with an average follow-up of 61 months (range, 24-105 months) after distal humerus hemiarthroplasty using a triceps preserving approach were studied. QuickDASH and Oxford Elbow Score assessed patient reported outcomes. Clinical and radiographic assessments comprised range of motion, grip strength, instability, implant loosening, chondral wear, heterotopic ossification and condylar union. RESULTS: Average QuickDASH was 14.9 (range, 0-63) and Oxford Elbow Score 40.35 (range, 25-48). Mean flexion arc was 108°, extension deficit 17° and pronosupination arc 155°. Average operative sided grip strength was 31.05 kg versus 31.13 kg contralaterally. Column preservation had no statistically significant effect on QuickDASH (p = 0.75), Oxford Elbow Score (p = 0.78), flexion-extension (p = 0.87), pronosupination (p = 0.78) or grip strength (p = 0.87). No progressive radiographic loosening or symptomatic chondral wear occurred. All fixed columns united. Three cases of immediate post-operative laxity fully resolved on elbow mobilisation. Four post-operative complications required further surgery: one ulnar neuropathy, one heterotopic ossification, one wound breakdown and one traumatic dislocation. CONCLUSION: Medium-term outcome of distal humerus hemiarthroplasty for acute unreconstructable distal humeral fractures is reliable irrespective of condylar preservation.

RESUMO

We present a case of volar rotatory subluxation of index finger proximal interphalangeal joint (PIPJ) following a skiing accident. The injury was initially perceived to be a central slip rupture and treatment was directed as such. After the initial delay in the diagnosis, the patient underwent surgery during which his radial collateral ligament was found to be avulsed from the proximal origin, the radial lateral band palmarly subluxed and was interposed in the joint space. This structure was also adhered to the uninjured volar plate.PIPJ volar rotatory subluxation could be readily missed in the acute setting. Without surgery, the functional outcome could be mediocre and to the patient's detriment.

RESUMO

PURPOSE: The porosity of the femoral head prepared for hip resurfacing has not been previously described. This is important as greater pore size increases the penetration of bone cement and excessive cement penetration can cause osteonecrosis. METHODS: 96 osteoarthritic femoral heads were harvested at total hip arthroplasty and prepared for hip resurfacing. The porosity of the bone cement interface in hip resurfacing was calculated from digitised black and white photographs using MatLab software. RESULTS: The mean porosity was 0.63. Increased porosity was associated with larger femoral heads in both the coronal and sagittal dimensions and cysts in the femoral head. It was not associated with gender, age, body mass index (BMI), smoking, alcohol or corticosteroid consumption. CONCLUSION: The porosity of the femoral head has been shown to be 0.63. Future studies of cementing techniques in hip resurfacing should include this porosity in their designs. The surgeon prior to hip resurfacing should consider altering his cementing technique when cysts are present on the preoperative radiographs.

RESUMO

BACKGROUND: Malunited proximal radius fractures causing dislocation of the radio-capitellar joint are rare. We present a case of a two-year-old female patient with such an injury who was treated with a proximal radius osteotomy with good long-term outcomes. METHOD/RESULTS: Case study of a single patient with a malunited proximal radius fracture which was identified as causing radio-capitellar dislocation who underwent corrective osteotomy with a good result. CONCLUSION: Our opinion is that a corrective osteotomy for a malunited proximal radius fracture causing radio-capitellar dislocation is a sound treatment option and that no supplementary soft tissue reconstruction such as annular ligament exploration/reconstruction is necessary.

RESUMO

BACKGROUND: Scaphoid fractures account for 90% of carpal fractures and occur predominantly in young men. The use of immediate surgical fixation to manage this type of fracture has increased, despite insufficient evidence of improved outcomes over non-surgical management. The SWIFFT trial compared the clinical effectiveness of surgical fixation with cast immobilisation and early fixation of fractures that fail to unite in adults with scaphoid waist fractures displaced by 2 mm or less. METHODS: This pragmatic, parallel-group, multicentre, open-label, two-arm, randomised superiority trial included adults (aged 16 years or older) who presented to orthopaedic departments of 31 hospitals in England and Wales with a clear bicortical fracture of the scaphoid waist on radiographs. An independent remote randomisation service used a computer-generated allocation sequence with randomly varying block sizes to randomly assign participants (1:1) to receive either early surgical fixation (surgery group) or below-elbow cast immobilisation followed by immediate fixation if non-union of the fracture was confirmed (cast immobilisation group). Randomisation was stratified by whether or not there was displacement of either a step or a gap of 1-2 mm inclusive on any radiographic view. The primary outcome was the total patient-rated wrist evaluation (PRWE) score at 52 weeks after randomisation, and it was analysed on an available case intention-to-treat basis. This trial is registered with the ISRCTN registry, ISRCTN67901257, and is no longer recruiting, but long-term follow-up is ongoing. FINDINGS: Between July 23, 2013, and July 26, 2016, 439 (42%) of 1047 assessed patients (mean age 33 years; 363 [83%] men) were randomly assigned to the surgery group (n=219) or to the cast immobilisation group (n=220). Of these, 408 (93%) participants were included in the primary analysis (203 participants in the surgery group and 205 participants in the cast immobilisation group). 16 participants in the surgery group and 15 participants in the cast immobilisation group were excluded because of either withdrawal, no response, or no follow-up data at 6, 12, 26, or 52 weeks. There was no significant difference in mean PRWE scores at 52 weeks between the surgery group (adjusted mean 11·9 [95% CI 9·2-14·5]) and the cast immobilisation group (14·0 [11·3 to 16·6]; adjusted mean difference -2·1 [95% CI -5·8 to 1·6], p=0·27). More participants in the surgery group (31 [14%] of 219 participants) had a potentially serious complication from surgery than in the cast immobilisation group (three [1%] of 220 participants), but fewer participants in the surgery group (five [2%]) had cast-related complications than in the cast immobilisation group (40 [18%]). The number of participants who had a medical complication was similar between the two groups (four [2%] in the surgery group and five [2%] in the cast immobilisation group). INTERPRETATION: Adult patients with scaphoid waist fractures displaced by 2 mm or less should have initial cast immobilisation, and any suspected non-unions should be confirmed and immediately fixed with surgery. This treatment strategy will help to avoid the risks of surgery and mostly limit the use of surgery to fixing fractures that fail to unite.

RESUMO

OBJECTIVE: The purpose of this study was to identify the external and internal reliability and responsiveness of the validated patient-reported outcome measures (PROMs) of neck pain to a standardized regimen of physiotherapy administered acutely after mild whiplash injury using the clinically significant improvement components of the Patient Global Impression of Change (PGIC) as the outcome measure. METHODS: Eighty-six patients with neck pain alone were referred for physiotherapy within 2 weeks of whiplash injury. They completed the Copenhagen, Northwick Park (NP), and Neck Bournemouth (NBQ) questionnaires and the Neck Disability Index (NDI) before starting and after treatment when they also completed the PGIC. Treatment comprised deep soft tissue massage, myofascial releases, muscle energy techniques, joint articulation and manipulation techniques, and a home exercise program. The duration of treatment was between 3 and 6 weeks. A PGIC of 6 or 7 was considered to be clinically significant improvement. RESULTS: The external reliability of the PROMs was >0.7 and internal >0.87. All components of the PROMs contributed to the final score except headache in the Copenhagen and upper-limb dysesthesia in the NP. The most reliable questionnaire was the NBQ, which was significantly more responsive than the Copenhagen (P = .008). The NBQ was slightly more responsive than the NDI and NP. The NBQ and NDI were successfully completed more frequently than the NP and Copenhagen. CONCLUSION: The NP, NDI, and NBQ are all reliable and responsive measures of change after physiotherapy for neck pain after acute whiplash injury.

RESUMO

Background Ulnocarpal impaction occurs when there is excessive loading between the ulnar carpus and the distal ulna. Ulnar shortening osteotomies (USOs) decompress the ulnocarpal joint. Many studies have evaluated USO but none have considered the effect of early active mobilization on union rate. Questions Does early active mobilization affect rate of union following USO? Does early active mobilization affect rate of complications following USO? Patients and Methods We performed a retrospective review of 15 consecutive patients that underwent 16 USOs between 2011 and 2015. There were seven males and eight females. Median age at time of shortening osteotomy was 47 years (range: 11-63 years). The median time of the procedure was 62 minutes (range: 45-105 minutes) and the median change in ulnar variance was 5.5 mm (range: 0-10.5 mm). Six patients were initially immobilized in incomplete plaster casts postoperatively, while the remainder had only wool and crepe dressings. Early active mobilization commenced after the first postoperative visit at 12 days. Results There was a 100% union rate in our series and 12 patients were pain-free at final follow-up. However, three of the patients with the longest times to union were smokers. Additionally, some patients may have achieved union between follow-up clinic visits. Conclusion Early active mobilization after USO does not affect union rate. Prospective, randomized studies are required to investigate the effect of early active mobilization in light of factors known to increase time to union, such as smoking. Level of Evidence This is a Level IV, case series.

RESUMO

Descriptions of multiple extensor slips and accessory extensor tendons of the hand are extensively published in the contemporary literature. Despite their varied anatomy, accessory tendons seldom have a functional implication for the patient. We report a case detailing a previously undescribed accessory extensor tendon of the hand, which resulted unusually in an aberration in the mechanics of a single digit. This was explored and corrected surgically, resulting in an excellent outcome for the patient.

RESUMO

Injuries to the elbow are commonly encountered in orthopaedic practice. They range from low energy, simple isolated fractures, to high energy complex fracture dislocations with severe ligamentous disruption. Recognising the precise pattern of injury is critical in restoring elbow function and preventing chronic instability, pain and weakness. This article discusses the important osseous and ligamentous stabilisers of the elbow joint and provides management protocols for the common patterns of complex injury encountered by the practising surgeon.

RESUMO

BACKGROUND: Patient-reported outcome measures (PROMs) are important tools for assessing outcomes following injuries to the hand and wrist. Many commonly used PROMs have no evidence of reliability, validity, and responsiveness in a hand and wrist trauma population. This systematic review examines the PROMs used in the assessment of hand and wrist trauma patients, and the evidence for reliability, validity, and responsiveness of each measure in this population. METHODS: A systematic review of Pubmed, Medline, and CINAHL searching for randomized controlled trials of patients with traumatic injuries to the hand and wrist was carried out to identify the PROMs. For each identified PROM, evidence of reliability, validity, and responsiveness was identified using a further systematic review of the Pubmed, Medline, CINAHL, and reverse citation trail audit procedure. RESULTS: The PROM used most often was the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire; the Patient-Rated Wrist Evaluation (PRWE), Gartland and Werley score, Michigan Hand Outcomes score, Mayo Wrist Score, and Short Form 36 were also commonly used. Only the DASH and PRWE have evidence of reliability, validity, and responsiveness in patients with traumatic injuries to the hand and wrist; other measures either have incomplete evidence or evidence gathered in a nontraumatic population. CONCLUSIONS: The DASH and PRWE both have evidence of reliability, validity, and responsiveness in a hand and wrist trauma population. Other PROMs used to assess hand and wrist trauma patients do not. This should be considered when selecting a PROM for patients with traumatic hand and wrist pathology.

RESUMO

BACKGROUND: Rehabilitation protocols after distal biceps repair are highly variable, with many surgeons favoring at least 2 weeks of immobilization. Is this conservative approach necessary to protect the repair? METHODS: This was a consecutive series of 22 distal biceps tendon repairs in which a cortical button system was used. Patients were encouraged to mobilize their elbow actively from the day of surgery. Physiotherapy commenced at 3 weeks, with strengthening exercises when full range of movement (ROM) was achieved. The primary outcome measured was the clinical integrity of the repaired tendon. Secondary outcomes comprised wound or nerve complication, elbow ROM, and patient-reported outcome measures (the 11-item version of the Disabilities of Arm, Shoulder and Hand, Mayo Elbow Performance Index, and Oxford Elbow Score). RESULTS: All patients were male, and the dominant arm was repaired in 60%. Mean age was 40.6 years (range, 27-62 years), and mean time to surgery was 17 days (range, 5-99 days). Mean follow-up was 16.6 months (range, 3.8-29 months). All tendons were clinically intact at time of review. No wound breakdown occurred. Mean extension was -6° (range, -10° to 10°), and flexion was 144° (range, 135°-150°). All patients achieved full pronosupination. ROM was equivalent to the uninjured arm (P = .7). The mean 11-item version of the Disabilities of Arm, Shoulder and Hand score was 2.7 (range, 0-15.9), the Mayo Elbow Performance Index was 97.8 (range, 70-100), and the Oxford Elbow Score was 46.9 (range, 43-48) at the latest follow-up. One-third of patients experienced a transient sensory neurapraxia. CONCLUSION: Immediate mobilization after biceps tendon repair with a cortical button is possible, and in this series was not associated with failure of the repair, wound breakdown, or patient dissatisfaction. However, this series emphasizes the high incidence of nerve complication that can be associated with the single transverse incision technique.

RESUMO

BACKGROUND: We aimed to determine the degree of contracture in the ring and little fingers at which hand function became importantly impaired. METHODS: Five activities of daily living were incorporated into a newly developed and validated Dupuytren's assessment tool (DAT). Sixty healthy participants were assessed with the DAT wearing a range of 12 dorsal blocking splints. Half wore them on their right little finger, the other half on their ring finger. These induced flexion deformities mimicking DC of the MCPJ, PIPJ and a combination of the two. The angles of flexion deformity at which important hand disability occurred were calculated using receiver operating characteristic curves. RESULTS: Clinically important hand disability occurred for the little finger MCPJ, PIPJ and combined MCPJ and PIPJ angulation at 52.5, 67.5, and 75 degrees respectively. For the ring finger joint, the angulations were 52.5, 67.5 and 75 degrees respectively. CONCLUSIONS: This information will provide information for clinicians and patients as to when clinically important disability tends to occur in DC.

RESUMO

We present the case of a lady with rapidly growing haemorraghic bullae in the digits of both hands. There was no effect of antibiotics and surgical debridement was detrimental. The lesions regressed following steroid therapy. We discuss the cutaneous complications of haematological malignancies. We emphasize the importance of avoiding surgery in these cases and explain that immunosuppressive therapy should form the basis of treatment.

RESUMO

PURPOSE: To compare the cement mantle characteristics associated with use of a narrow nozzle cement gun versus the use of a 60-mL catheter tip syringe. METHODS: Twelve cadaveric distal humeri were cemented with either a cement gun or a syringe without canal occlusion. The humeri were sectioned and photographed. The corticocancellous junction and the outer margin of the cement mantle were analyzed digitally. The corticocancellous junction defined the available area for cement penetration. The outline of the cement mantle defined the actual area of penetration. The ratio of penetration to the available area was recorded for each slice. The mean ratio for each humerus was multiplied by the number of slices in that sample containing cement to calculate a cement index. RESULTS: The cement penetration ratios observed in cross-sections at the same level and the cement index were significantly greater with the use of the cement gun than with the use of the syringe. There was no difference in the number of slices that contained cement. CONCLUSIONS: The use of a cement gun with a narrow nozzle improved cement mantle characteristics compared with the use of a syringe when measured in a cadaveric model in the absence of canal occlusion. CLINICAL RELEVANCE: Improving cement mantle characteristics may decrease the incidence of aseptic loosening after total elbow arythroplasty.

RESUMO

Pyogenic myositis is uncommon. It normally affects the large muscle groups in the lower limb or trunk and the most common causative organism is Staphylococcus aureus. We present a case of an immunocompetent man who, unusually, had a recurring form of the disease in subscapularis and teres minor. The causative organism was also highly unusual (Fusobacterium).

RESUMO

BACKGROUND: Arthroscopic triple fusion has several advantages over open techniques, but its use has yet to become widespread. Preliminary published techniques use five portals with neurovascular risk. Our aim was to assess the safety and efficacy of an alternative lateral two portal technique. METHODS: Four cadaveric hindfeet were arthroscopically prepared for a triple fusion using two lateral portals. The distance to relevant subcutaneous nerves was measured as well as the prepared joint surface percentage. RESULTS: Mean distance from mid-lateral portal to the nearest sural nerve branch was 22.3mm (range 20-24mm) and from the dorsolateral portal to the intermediate branch of the superficial peroneal nerve was 7.8mm (range 4-11mm). Mean percentages of joint preparation were 63% (talar head), 62% (navicular), 75% (calcaneum) and 74% (cuboid). CONCLUSIONS: Two lateral arthroscopic portals allow adequate joint preparation for triple fusion procedures. The proximity of subcutaneous nerves is important to appreciate when using these portals.
