The purpose of this study is to describe the use of the PHILOS plate (Synthes) in reverse configuration to treat complex distal humeral non-unions.

Non-union is a frequent complication of distal humeral fracture. It is a challenging problem due to the complex anatomy of the distal humerus, small distal fragment heavily loaded by the forearm acting as a long lever arm with powerful forces increasing the chances of displacement. Rigid fixation and stability with a device of high “pull-out” strength is required. The PHILOS plate has been used in reverse configuration to achieve good fixation while allowing central posterior placement of the implant.

11 patients with established non-union of distal humeral fractures were included in this study. No patient in whom this implant was used has been excluded. Initial fixation was revised using the PHILOS plate in reverse configuration and good fixation was achieved. Bone graft substitutes were used in all cases. Patients were followed to bony union, and functional recovery.

All fractures united. One required revision of plate due to fatigue failure. Average time to union was 8 months with excellent restoration of elbow function.

A reversed PHILOS plate provides an excellent method of fixation in distal humeral non-union, often complicated by distorted anatomy and previous surgical intervention. It has a high “pull-out” strength and may be placed in the centre of the posterior humerus, allowing proximal extension of the fixation as far as is required. It provides secure distal fixation without impinging on the olecranon fossa. It is more versatile and easier to use than available pre contoured plating systems.

The aim of this audit was to assess the union rate of humeral shaft fractures treated conservatively in a functional brace in our unit, compared to a “gold standard” of 98% as reported by Sarmiento (JBJS 1977). A retrospective clinical and radiographic review of 155 closed humeral shaft fractures managed with a humeral brace from 2005–2012 was performed. Pathological fractures and patients under 18 were excluded. The mean age was 60 (18–94) with 45 males and 72 females. 15 (10%) patients under 18 and 8 (5%) pathological fractures were excluded; 15 (10%) patients were lost to follow up. Of the remaining 117 fractures, 83 (71%) went on to union and 34 (29%) developed a non-union. Mean time to union was 131 days (47–622). 80% of distal fractures and 75% of midshaft fractures united but only 58% of proximal fractures went on to unite. There was no significant difference in union rates between multi fragmentary (> 3 parts) and simple fracture patterns (69% vs 71% respectively). Our study suggests that a lower threshold for operative intervention of proximal third humeral shaft fractures may be required

Fractures of the humeral diaphysis occur in a bimodal distribution and represent 3-5% of all fractures. Presently, the standard treatment of isolated humeral diaphyseal fractures is nonoperative care using splints, braces, and slings. Recent data has questioned the effectiveness of this strategy in ensuring fracture healing and optimal patient function. The primary objective of this randomized controlled trial (RCT) was to assess whether operative treatment of humeral shaft fractures with a plate and screw construct provides a better functional outcome than nonoperative treatment. Secondary objectives compared union rates and both clinical and patient-reported outcomes. Eligible patients with an isolated, closed humeral diaphyseal fracture were randomized to either nonoperative care (initial sugar-tong splint, followed by functional coaptation brace) or open reduction and internal fixation (ORIF; plate and screw construct). The primary outcome measure was the Disability Shoulder, Arm, Hand (DASH) score assessed at 2-, 6-, 16-, 24-, and 52-weeks. Secondary outcomes included the Short Musculoskeletal Functional Assessment (SMFA), the Constant Shoulder Score, range of motion (ROM), and radiographic parameters. Independent samples t-tests and Chi-squared analyses were used to compare treatment groups. The DASH, SMFA, and Constant Score were modelled over time using a multiple variable mixed effects model. A total of 180 patients were randomized, with 168 included in the final analysis. There were 84 patients treated nonoperatively and 84 treated with ORIF. There was no significant difference between the two treatment groups for age (mean = 45.4 years, SD 16.5 for nonoperative group and 41.7, SD 17.2 years for ORIF group; p=0.16), sex (38.1% female in nonoperative group and 39.3% female in ORIF group; p=0.87), body mass index (mean = 27.8, SD 8.7 for nonoperative group and 27.2, SD 6.2 for ORIF group; p=0.64), or smoking status (p=0.74). There was a significant improvement in the DASH scores at 6 weeks in the ORIF group compared to the nonoperative group (mean=33.8, SD 21.2 in the ORIF group vs. mean=56.5, SD=21.1 in the nonoperative group; p < 0 .0001). At 4 months, the DASH scores were also significantly better in the ORIF group (mean=21.6, SD=19.7 in the ORIF group vs. mean=31.6, SD=24.6 in the nonoperative group; p=0.009. However, there was no difference in DASH scores at 12-month follow-up between the groups (mean=8.8,SD=10.9 vs. mean=11.0, SD=16.9 in the nonoperative group; p=0.39). Males had improved DASH scores at all timepoints compared with females. There was significantly quicker time to union (p=0.016) and improved position (p < 0 .001) in the ORIF group. There were 13 (15.5%) nonunions in the nonoperative group and four (4.7%) combined superficial and deep infections in the ORIF group. There were seven radial nerve palsies in the nonoperative group and five (a single iatrogenic) radial nerve palsies in the ORIF group. This large RCT comparing operative and nonoperative treatment of humeral diaphyseal fractures found significantly improved functional outcome scores in patients treated surgically at 6 weeks and 4 months. However, the early functional improvement did not persist at the 12-month follow-up. There was a 15.5% nonunion rate, which required surgical intervention, in the nonoperative group and a similar radial nerve palsy rate between groups

Background. Peri-prosthetic humerus fractures are relatively uncommon occurrences that can be difficult to manage non-operatively. Locking plate technology has enhanced the surgical management of these fractures. We describe an osteosynthesis technique utilizing a locking plate with eccentrically placed screw holes to place “skive screws” in the proximal end of the plate to achieve fixation around the stem of the implant. Methods. A retrospective review of prospectively collected data was performed for a consecutive series of patients treated with this skive screw technique from May 2011 to September 2014. Seven patients presented with postoperative type B peri-prosthetic humerus fractures. Average follow-up was 24 months. Radiographic analysis was performed on most recent postoperative imaging. Clinical outcomes were assessed using VAS pain, ASES total score, ASES functional score, SST, SANE, range of motion and strength. Results. At an average of follow-up of 24 months, all patients demonstrated fracture healing. Functional outcomes were limited with only two patients achieving forward elevation above 90 degrees and average ASES Function score was 27.5. Pain relief was nearly uniform with an average VAS Pain score of 0.5 (Figure 1). Conclusions. Peri-prosthetic humeral shaft fractures can be successfully treated with hybrid fixation technique using a locking plate with eccentric holes that facilitate placement of proximal “skive screws”. Using this technique, a 100% union rate was observed with excellent pain relief

The patterns of nerve and associated skeletal injury were reviewed in 84 patients referred to the brachial plexus service who had damage predominantly to the infraclavicular brachial plexus and its branches. Patients fell into four categories: 1. Anterior glenohumeral dislocation (46 cases); 2. ‘Occult’ shoulder dislocation or scapular fracture (17 cases); 3. Humeral neck fracture (11 cases); 4. Arm hyperextension (9 cases). The axillary (38/46) and ulnar (36/46) nerves were most commonly injured as a result of glenohumeral dislocation. The axillary nerve was ruptured in only 2 patients who had suffered high energy trauma. Ulnar nerve recovery was often incomplete. ‘Occult’ dislocation refers to patients who had no recorded shoulder dislocation but the history was suggestive that dislocation had occurred with spontaneous reduction. These patients and those with scapular fractures had a similar pattern of nerve involvement to those with known dislocation, but the axillary nerve was ruptured in 11 of 17 cases. In cases of humeral neck fracture, nerve injury resulted from medial displacement of the humeral shaft. Surgery was performed in 7 cases to reduce and fix the fracture. Arm hyperextension cases were characterised by injury to the musculocutaneous nerve, with the nerve being ruptured in 8 of 9. Five had humeral shaft fracture or elbow dislocation. There was variable involvement of the median and radial nerves, with the ulnar nerve being least affected. Most cases of infraclavicular brachial plexus injury associated with shoulder dislocation can be managed without operation. Early nerve exploration and repair should be considered for:. Axillary nerve palsy without recorded shoulder dislocation or in association with fracture of the scapula. Musculocutaneous nerve palsy with median and/or radial nerve palsy. Urgent operation is necessary for nerve injury resulting from fracture of the humeral neck to relieve ongoing pressure on the nerves

Durable humeral component fixation in shoulder arthroplasty is necessary to prevent painful aseptic loosening and resultant humeral bone loss. Causes of humeral component loosening include stem design and material, stem length and geometry, ingrowth vs. ongrowth surfaces, quality of bone available for fixation, glenoid polyethylene debris osteolysis, exclusion of articular particulate debris, joint stability, rotator cuff function, and patient activity levels. Fixation of the humeral component may be achieved by cement fixation either partial or complete and press-fit fixation. During the past two decades, uncemented humeral fixation has become more popular, especially with short stems and stemless press fit designs. Cemented humeral component fixation risks difficult and complicated revision surgery, stress shielding of the tuberosities and humeral shaft periprosthetic fractures at the junction of the stiff cemented stem and the remaining humeral shaft. Press fit fixation may minimise these cemented risks but has potential for stem loosening. A randomised clinical trial of 161 patients with cemented vs. press fit anatomic total shoulder replacements found that cemented fixation of the humeral component provided better quality of life, strength, and range of motion than uncemented fixation but longer operative times. Another study found increased humeral osteolysis (43%) associated with glenoid component loosening and polyethylene wear, while stress shielding was seen with well-fixed press fit humeral components. During reverse replacement the biomechanical forces are different on the humeral stem. Stem loosening during reverse replacement may have different factors than anatomic replacement. A systemic review of 41 reverse arthroplasty clinical studies compared the functional outcomes and complications of cemented and uncemented stems in approximately 1800 patients. There was no difference in the risk of stem loosening or revision between cemented and uncemented stems. Uncemented stems have at least equivalent clinical and radiographic outcomes compared with cemented stems during reverse shoulder arthroplasty. Durable humeral component fixation in shoulder arthroplasty is associated with fully cemented stems or well ingrown components that exclude potential synovial debris that may cause osteolysis

Aims

To determine the impact of COVID-19 on orthopaediatric admissions and fracture clinics within a regional integrated care system (ICS).

Methods

A retrospective review was performed for all paediatric orthopaedic patients admitted across the region during the recent lockdown period (24 March 2020 to 10 May 2020) and the same period in 2019. Age, sex, mechanism, anatomical region, and treatment modality were compared, as were fracture clinic attendances within the receiving regional major trauma centre (MTC) between the two periods.

This prospective five-year study analyses the impact of methicillin-resistant Staphylococcus aureus (MRSA) on an Irish orthopaedic unit. We identified 318 cases of MRSA, representing 0.76% of all admissions (41 971). A total of 240 (76%) cases were colonised with MRSA, while 120 (37.7%) were infected. Patients were admitted from home (218; 68.6%), nursing homes (72; 22.6%) and other hospitals (28; 8.8%). A total of 115 cases (36.6%) were colonised or infected on admission. Many patients were both colonised and infected at some stage. The length of hospital stay was almost trebled because of the presence of MRSA infection.

Encouragingly, overall infection rates have not risen significantly over the five years of the study despite increased prevalence of MRSA. However, the financial burden of MRSA is increasing, highlighting the need for progress in understanding how to control this resistant pathogen more effectively.
