Non-operative management of terrible triad injuries of the elbow; not so terrible?

Introduction: Terrible triad injuries (TTIs) of the elbow have traditionally been reported to have poor outcomes, hence requiring surgical stabilisation. We identified and reviewed patients with TTIs treated non-operatively within our department. Methods: We retrospectively reviewed patients with TTI treated non-operatively with standardised elbow-instability rehabilitation from 2010 to 2020. We used Mason and Morrey classifications for radial head and coronoid fractures, respectively. Non-operative indications included a congruent joint on CT, significant co-morbidities pre-disposing to high-risk surgery and/or patient preference. Outcomes included Oxford Elbow Score (OES), ROM and complications. Results: Nineteen patients were included (mean age 49; 37% female). At an average of 6 years (range 2-11 years) post-treatment, mean OES was 46 ± 7. At last clinic review, mean 6 months (2-15), average ROM was 131 ± 11° flexion, 8 ± 10° extension, 85 ± 12° supination and 85 ± 13° pronation. One patient required arthrolysis and another had an incongruent ulnohumeral joint which developed clicking with a functional ROM. Conclusion: Our report suggests non-operatively managed and appropriately rehabilitated TTI injuries can achieve good function and ROM. We recommend conservative management as a viable option in cases with joint congruency and no mechanical block in patients with significant co-morbidities or those refusing surgery but patients must be assessed on a case-by-case basis.

Radial head replacement - A comprehensive review.

Background: Radial head fractures represent 1-4% of all adult fractures and 1/3rd of elbow fractures (Kaas et al., 2010). Radial head is an important secondary stabilier of the elbow. The aim of the treatment of radial head fractures is to achieve stability and good functional outcome. Radial head replacement (RHR) is indicated when robust reconstruction and fixation of the fracture fragments is not possible. Methods: This article explores history and evolution, anatomical considerations, biomechanics, implant designs, indications, surgical outcomes and controversies in radial head replacement based on current evidence. Results: There is a wide range of RHR designs available without conclusive evidence to support the superiority of one design over the other. Ranges of motion, functional outcomes and complication were comparable among different designs with a high incidence of complications reported in many studies. Conclusion: RHR remains a good option in unreconstructible radial head fractures, with potential to regain excellent function. It is imperative to continue with the quest to innovate and improve on current designs, to reduce complications in the long term.

Reliability analysis of radiologic and intraoperative loosening in total elbow arthroplasty.

BACKGROUND: Revisions of total elbow arthroplasties (TEAs) are commonly performed because of prosthetic loosening. UK National Joint Registry data show that TEA revisions are becoming increasingly common, with 123 TEA revisions performed in 2018 and 76 performed in 2017. TEA radiologic assessment is based on subjective interpretation with no published criteria. We defined TEA loosening by the presence of at least one of the following criteria: (1) progressive widening of the bone-cement, bone-prosthesis, or cement-prosthesis interface; (2) fragmentation or fracture of cement; (3) prosthetic component migration; and (4) bead shedding in porous-coated prostheses. Using this definition, we looked at interobserver and intraobserver agreement on radiologic loosening and compared this assessment with intraoperative findings. METHODS: In our tertiary care center, we conducted a retrospective review to identify TEA revisions performed between November 2008 and July 2018. Radiologic implant loosening was independently assessed by 5 orthopedic surgeons. Interobserver agreement (κ coefficient) was calculated. The majority's view of radiologic loosening was compared with intraoperative findings. RESULTS: We identified 93 sets of radiographs with implant stability clearly documented in their operative notes. The κ coefficient between assessors for humeral implant loosening was 0.87 (almost perfect). The κ coefficient for ulnar loosening was 0.75 (substantial). The κ coefficients for radiologic and intraoperative findings of humeral loosening and ulnar loosening were 0.67 and 0.71 (substantial), respectively. Intraobserver reliability was almost perfect for humeral loosening (κ = 0.86) and substantial for ulnar loosening (κ = 0.74). CONCLUSION: Our definition of loosening provides reproducible interobserver and intraobserver agreement on radiographic component loosening. In our center's experience, radiologic findings may not translate to intraoperative findings, and we would advise that surgical strategies for TEA revision include the possibility of needing to perform a dual-implant exchange.

Revision total elbow arthroplasty: Is it safe to perform a single-stage revision for presumed aseptic loosening based on clinical assessment, normal inflammatory markers, and a negative aspiration?

BACKGROUND: Revision total elbow arthroplasty (TEA) is a challenging procedure that is becoming increasingly common. In our unit, we regard it as essential to exclude infection as the underlying cause of TEA loosening. In all patients with arthroplasty loosening, we undertake a careful history and examination, perform radiographs, monitor inflammatory markers, and undertake a joint aspiration. If any investigation suggests infection as the etiology, then a 2-stage revision is undertaken. Open biopsies are not routinely performed. The aim was to ascertain from our outcomes whether it is safe to perform a single-stage revision for presumed aseptic loosening using these criteria. METHODS: A retrospective review of a consecutive series of revision TEAs was performed in our unit over a 10-year period (2008-2018). Single-stage revisions performed for presumed aseptic loosening were identified. Case notes, radiographs, bloods, aspiration results, and microbiology of tissue samples taken at revision were reviewed. RESULTS: A total of 123 revision elbow arthroplasty cases were performed in the study period. Sixty cases were revised for preoperatively proven infection, instability, or implant failure and were excluded from this study. In 63 cases, aseptic loosening was diagnosed based on history, clinical examination, blood markers, and aspiration. There were 21 dual-component and 42 single-component revisions. In the dual-component revision group, tissue samples taken at the time of revision were positive in only 1 case (5%). In the single-component revision group, positive culture samples were present in 3 cases (7%). χ2 analysis showed no significant difference between single- and dual-component revisions (P = .76). No cases with positive culture samples from either group have required subsequent revision surgery. CONCLUSION: Given the results of this study, we conclude that is safe to perform single-stage revision arthroplasty for implant loosening based on history, examination, normal inflammatory markers, and negative aspiration results without the need for open biopsy.

Sternoclavicular joint dislocation and its management: A review of the literature.

Dislocations of the sternoclavicular joint (SCJ) occur with relative infrequency and can be classified into anterior and posterior dislocation, with the former being more common. The SCJ is inherently unstable due to its lack of articular contact and therefore relies on stability from surrounding ligamentous structures, such as the costoclavicular, interclavicular and capsular ligaments. The posterior capsule has been shown in several studies to be the most important structure in determining stability irrespective of the direction of injury. Posterior dislocation of the SCJ can be associated with life threatening complications such as neurovascular, tracheal and oesophageal injuries. Due to the high mortality associated with such complications, these injuries need to be recognised acutely and managed promptly. Investigations such as X-ray imaging are poor at delineating anatomy at the level of the mediastinum and therefore CT imaging has become the investigation of choice. Due to its rarity, the current guidance on how to manage acute and chronic dislocations is debatable. This analysis of historical and recent literature aims to determine guidance on current thinking regarding SCJ instability, including the use of the Stanmore triangle. The described methods of reduction for both anterior and posterior dislocations and the various surgical reconstructive techniques are also discussed.

A rare case of floating clavicle and a novel technique for stabilizing the sternoclavicular joint.

We present the first ever case report of a floating clavicle with a unique combination of a posterior sternoclavicular joint dislocation and an associated grade III acromioclavicular joint dislocation. We treated this injury surgically by stabilizing both ends of clavicle using a polyester surgical mesh device (LockDown™; Mandaco 569 Limited, Redditch, UK; previously called the Nottingham Surgilig).

Myositis ossificans of the humeral insertion of pectoralis major.

We report on a rare case of myositis ossificans of the humeral insertion of pectoralis major muscle following a single episode of trauma which, to our knowledge, has not previously been documented.

Extended lateral approach for elective hind foot surgery--a safe and versatile incision.

AIM: The aim of our study was to review our experience of the extended lateral approach to the hind foot in treatment of non-traumatic foot disorders with particular reference to wound complications. MATERIALS AND METHODS: We retrospectively reviewed 51 consecutive patients who under went extended lateral approach to the hind foot for treatment of various non traumatic foot disorders. We documented the indication for surgery, co-morbidity, quality of wound healing and other wound related problems. RESULTS: The mean age was 47.9. There were three superficial wound infections (5.8%). One had slight sensory loss close to the scar, one developed hypersensitivity over the scar. There was no wound break down or any deep infection. No sural nerve deficit was noted. Six patients had the calcaneal screw removed due to prominent metal work (11.7%). CONCLUSION: The extended lateral approach to hind foot is safe in the surgical treatment of a wide variety of non-traumatic foot conditions. Despite the larger deep dissection, the arterial anatomy ensures reliable wound healing and a low incidence of wound complications.

MRSA colonisation in patients admitted with hip fracture: implications for prevention of surgical site infection.

In a prospective study we assessed 440 patients, sequentially admitted to the trauma unit with hip fracture. Of the 403 who had a swab on admission, 5.2% (21/403) were found to be colonised with MRSA. Fifty two percent of MRSA colonised patients were admitted from their own home, 29% from residential homes and 19% from nursing homes. MRSA colonisation was found in 3.6% of patients admitted from their own home, 10.9% of residential home patients, and 17.4% of nursing home patients. A high proportion (80.9%) of colonised patients had been admitted to a hospital within the previous one year, and the high prevalence of previous hospitalisation among people from institutional care may explain the higher rates of MRSA carriage among these individuals. When a patient gives a history of hospitalisation within the previous year, it is clearly sensible to consider the use of an agent such as teicoplanin for perioperative prophylaxis.

Functional outcome following proximal humeral interlocking system plating for displaced proximal humeral fractures.

AIM: To assess the functional outcome following internal fixation with the PHILOS (proximal humeral interlocking system) for displaced proximal humeral fractures. PATIENTS AND METHODS: We reviewed 30 consecutive patients treated surgically with the proximal humeral locking plate for a displaced proximal humeral fracture. Functional outcome was determined using the American Shoulder and Elbow Society (ASES) score and Constant Murley score. RESULTS: Average age of the patients was 58 years (range, 19-92 years). The average overall ASES score was 66.5. The average overall Constant score was 57.5. CONCLUSION: Our results show that good fracture stability was achieved, and the functional outcome was very good in younger patients and it declined with increasing age. Early mobilization of the shoulder can be achieved without compromising fracture union.

Treatment of mid-shaft clavicle fractures: A comparative study.

We retrospectively evaluated 51 patients (17 in each of three groups) with mid shaft clavicle fractures. Group 1 underwent intramedullary stabilization using clavicle pins. Group 2 underwent open reduction and internal fixation using plates and group 3 underwent non operative treatment with a sling. Group1 patients progressed to union within 8 to 12 weeks. In Group 2, six patients had scar related pain and two had prominent metal work and discomfort and in group 3, three patients developed non union and one had symptomatic malunion. Our results suggest that the displaced and shortened midshaft clavicle fractures require operative fixation and the techniques of clavicle pinning resulted in less complications, short hospital stay and good functional outcome.
