Aims

In patients with a failed radial head arthroplasty (RHA), simple removal of the implant is an option. However, there is little information in the literature about the outcome of this procedure. The aim of this study was to review the mid-term clinical and radiological results, and the rate of complications and removal of the implant, in patients whose initial RHA was undertaken acutely for trauma involving the elbow.

Aims

The aim of this study was to evaluate the outcome of complex radial head fractures at mid-term follow-up, and determine whether open reduction and internal fixation (ORIF) or radial head arthroplasty (RHA) should be recommended for surgical treatment.

Aims

The ulna is an extremely rare location for primary bone tumours of the elbow in paediatrics. Although several reconstruction options are available, the optimal reconstruction method is still unknown due to the rarity of proximal ulna tumours. In this study, we report the outcomes of osteoarticular ulna allograft for the reconstruction of proximal ulna tumours.

Aims

To propose a new method for evaluating paediatric radial neck fractures and improve the accuracy of fracture angulation measurement, particularly in younger children, and thereby facilitate planning treatment in this population.

Aims

Isolated fractures of the ulnar diaphysis are uncommon, occurring at a rate of 0.02 to 0.04 per 1,000 cases. Despite their infrequency, these fractures commonly give rise to complications, such as nonunion, limited forearm pronation and supination, restricted elbow range of motion, radioulnar synostosis, and prolonged pain. Treatment options for this injury remain a topic of debate, with limited research available and no consensus on the optimal approach. Therefore, this trial aims to compare clinical, radiological, and functional outcomes of two treatment methods: open reduction and internal fixation (ORIF) versus nonoperative treatment in patients with isolated ulnar diaphyseal fractures.

Aims

Acute and chronic injuries of the interosseus membrane can result in longitudinal instability of the forearm. Reconstruction of the central band of the interosseus membrane can help to restore biomechanical stability. Different methods have been used to reconstruct the central band, including tendon grafts, bone-ligament-bone grafts, and synthetic grafts. This Idea, Development, Exploration, Assessment, and Long-term (IDEAL) phase 1 study aims to review the clinical results of reconstruction using a synthetic braided cross-linked graft secured at either end with an Endobutton to restore the force balance between the bones of the forearm.

Aims

This study aimed to evaluate rasterstereography of the spine as a diagnostic test for adolescent idiopathic soliosis (AIS), and to compare its results with those obtained using a scoliometer.

Aims

Multiple secondary surgical procedures of the shoulder, such as soft-tissue releases, tendon transfers, and osteotomies, are described in brachial plexus birth palsy (BPBP) patients. The long-term functional outcomes of these procedures described in the literature are inconclusive. We aimed to analyze the literature looking for a consensus on treatment options.

Despite being one of the most common injuries around the elbow, the optimal treatment of olecranon fractures is far from established and stimulates debate among both general orthopaedic trauma surgeons and upper limb specialists. It is almost universally accepted that stable non-displaced fractures can be safely treated nonoperatively with minimal specialist input. Internal fixation is recommended for the vast majority of displaced fractures, with a range of techniques and implants to choose from. However, there is concern regarding the complication rates, largely related to symptomatic metalwork resulting in high rates of implant removal. As the number of elderly patients sustaining these injuries increases, we are becoming more aware of the issues associated with fixation in osteoporotic bone and the often fragile soft-tissue envelope in this group. Given this, there is evidence to support an increasing role for nonoperative management in this high-risk demographic group, even in those presenting with displaced and/or multifragmentary fracture patterns. This review summarizes the available literature to date, focusing predominantly on the management techniques and available implants for stable fractures of the olecranon. It also offers some insights into the potential avenues for future research, in the hope of addressing some of the pertinent questions that remain unanswered.

Over 500 supracondylar humerus fractures (SCHF) are treated at our institution each year. Our standard post-operative pathway includes a 3-week visit for splint removal, wire removal, and radiographs. Subsequent follow-up occurs at 12 weeks for a clinical examination. In an effort to minimize unnecessary follow-up visits, we investigated whether photographs and/or patient-reported outcome measure (PROM) scores could identify patients who do not need routine 3-month in-person follow-up. At the 3-month visit, 248 SCHF patients (mean 6.2 yrs; 0.75-11yrs) had bilateral elbow motion (ROM) and carrying angles measured; and photographs documenting frontal and sagittal alignment of both injured and uninjured upper extremities, in both maximum elbow flexion and extension. Two independent assessors made the same measurements off the clinical photographs to compare these with the clinical measurements. Two PROMs: Self-Assessment Questionnaire (SAQ: 0 best to 14 worst) and QuickDASH (0 best to 100 worst) were completed at the 3-month visit. Inter-rater reliability of the photograph measurements was excellent (Kappa: 0.88-0.93), but weakly concordant with clinical measurements (carrying angle Kappa=0.51;max flexion Kappa=0.68;max extension Kappa=0.64). SAQ moderately correlated with QuickDASH (Kappa=0.59) and performed better at identifying patients with abnormalities. SAQ score ≥ 4 identified patients meeting 3-month follow-up criteria, with sensitivity: 36.1%; specificity: 96.8% and negative-predictive-value (NPV): 87%. We did not find that photographs were reliable. Although SAQ-score has high NPV, a more sensitive fracture-specific PROM is needed to identify patients who do not need a 3-month follow-up visit

Aims. The conventionally described mechanism of distal biceps tendon rupture (DBTR) is of a ‘considerable extension force suddenly applied to a resisting, actively flexed forearm’. This has been commonly paraphrased as an ‘eccentric contracture to a flexed elbow’. Both definitions have been frequently used in the literature with little objective analysis or citation. The aim of the present study was to use video footage of real time distal biceps ruptures to revisit and objectively define the mechanism of injury. Methods. An online search identified 61 videos reporting a DBTR. Videos were independently reviewed by three surgeons to assess forearm rotation, elbow flexion, shoulder position, and type of muscle contraction being exerted at the time of rupture. Prospective data on mechanism of injury and arm position was also collected concurrently for 22 consecutive patients diagnosed with an acute DBTR in order to corroborate the video analysis. Results. Four videos were excluded, leaving 57 for final analysis. Mechanisms of injury included deadlift, bicep curls, calisthenics, arm wrestling, heavy lifting, and boxing. In all, 98% of ruptures occurred with the arm in supination and 89% occurred at 0° to 10° of elbow flexion. Regarding muscle activity, 88% occurred during isometric contraction, 7% during eccentric contraction, and 5% during concentric contraction. Interobserver correlation scores were calculated as 0.66 to 0.89 using the free-marginal Fleiss Kappa tool. The prospectively collected patient data was consistent with the video analysis, with 82% of injuries occurring in supination and 95% in relative elbow extension. Conclusion. Contrary to the classically described injury mechanism, in this study the usual arm position during DBTR was forearm supination and elbow extension, and the muscle contraction was typically isometric. This was demonstrated for both video analysis and ‘real’ patients across a range of activities leading to rupture. Cite this article: Bone Jt Open 2022;3(10):826–831

Aims

The aim of this study was to assess and compare active rotation of the forearm in normal subjects after the application of a short-arm cast (SAC) in the semisupination position and a long-arm cast (LAC) in the neutral position. A clinical study was also conducted to compare the functional outcomes of using a SAC in the semisupination position with those of using a LAC in the neutral position in patients who underwent arthroscopic triangular fibrocartilage complex (TFCC) foveal repair.

Abstract. Objectives. Falling studies have been conducted in controlled environments but not in field studies for ethical reasons; this limits the validity and applicability of previous studies. We performed field studies on existing YouTube © videos of skateboarders falling. The aims were to measure the wrist angle at impact on videos of real unprotected falls and to study the dynamics of the upper limbs when falling. Methods. Youtube © videos of skateboarders falling were studied assessing the direction of the fall, the positions of both upper limbs and especially the wrists on impact. This study would not be ethical by other means. Results. In study one (the more quantitative study) there were 48 men and 50 falls. The mean elbow flexion was 300 (range 00 to 800) and the mean maximal wrist extension was 800 (range 500 to 1100). The secondary wrist extended less or the same in > 90%. The second wrist only one (of 31) extended > 900 which should minimise the risk of toppling. Falls onto only one wrist gave significantly greater maximal wrist extension. In the second more qualitative study we observed the “upper limb falling reflex” where the response to falling is for the upper limb(s) to align with the direction of falling of the body with the elbow mostly but not fully extended. Initially the wrists extend c. 400–500 with the fingers held mildly flexed. Immediately before impact the fingers hyper-extend with some compensatory wrist flexion to c. 300. The fingertips impact the ground first followed by the hand. Conclusion. These studies confirm wrist extension at impact around 800 but the wrist(s) may hyper-extend risking toppling. Falls on both wrists minimise the risk of toppling. The “upper limb falling reflex” is defined; it is a rapid dynamic response leading to the fingers impacting the ground first on falling.

Introduction and Objective. There remains much debate regarding the optimal method for surgical management of patients with long head of biceps pathology. The aim of this study was to compare the outcomes of tenotomy versus tenodesis. Materials and Methods. This systematic review and meta-analysis was registered on PROSPERO (ref: CRD42020198658). Electronic databases searched included EMBASE, Medline, PsycINFO, and Cochrane Library. Randomized controlled trials (RCTs) comparing tenotomy versus tenodesis were included. Risk of bias within studies was assessed using the Cochrane risk of bias v2.0 tool and the Jadad score. The primary outcome included patient reported functional outcome measures pooled using standardized mean difference (SMD) and a random effects model. Secondary outcome measures included visual analogue scale (VAS), rate of cosmetic deformity (Popeye sign), range of motion, operative time, and elbow flexion strength. Results. 751 patients from 10 RCTs demonstrated (369 tenotomy vs 382 tenodesis) were included in the meta-analysis. Pooled analysis of all PROMs data demonstrated comparable outcomes between tenotomy vs tenodesis (SMD 0.17 95% CI −0.02 to 0.36, p=0.09). Sensitivity analysis comparing RCTs involving patients with and without an intact rotator cuff did not change the primary outcome. Secondary outcomes including VAS, shoulder external rotation, and elbow flexion strength did not reveal any significant difference. Tenodesis resulted in a lower rate of Popeye deformity (OR 0.27 95% CI 0.16 to 0.45, p<0.00001). Conclusions. Aside from a lower rate of cosmetic deformity, tenodesis yielded no measurable significant benefit to tenotomy for addressing pathology in the long head of biceps. This finding was irrespective of the whether the rotator cuff was intact

Acute distal biceps tendon repair reduces fatigue-related pain and minimises loss of forearm supination and elbow flexion strength. We report the short- and long-term outcome following repair using an EndoButton technique. Between 2010 – 2018, 102 patients (101 males; mean age 43 years) underwent acute (□6 weeks) distal biceps tendon repair using an EndoButton technique. The primary short-term outcome was complications. The primary long-term outcome was the Quick-DASH (Q-DASH). Secondary outcomes included the Oxford Elbow Score (OES), EuroQol-5D-3L (EQ-5D), return to function and satisfaction. At mean short-term follow-up of 4 months (2.0 – 55.5) eight patients (7.8%) experienced a major complication and 34 patients (33.3%) experienced a minor complication. Major complications included re-rupture (n=3, 2.9%), unrecovered nerve injury (n=4, 3.9%) and surgery for heterotopic ossification excision (n=1, 1.0%). Three patients (2.9%) required surgery for a complication. Minor complications included neuropraxia (n=27, 26.5%) and superficial infection (n=7, 6.9%). At mean follow-up of 5 years (1 – 9.8) outcomes were collected from 86 patients (84.3%). The median Q-DASH, OES, EQ-5D and satisfaction scores were 1.2 (IQR 0 – 5.1), 48 (IQR, 46 – 48), 0.80 (IQR, 0.72 – 1.0) and 100/100 (IQR, 90 – 100) respectively. Most patients returned to sport (82.3%) and employment (97.6%) following surgery. Unrecovered nerve injury was associated with a poor outcome according to the Q-DASH (p< 0.001), although re-rupture and further surgery were not (p > 0.05). Acute distal biceps tendon repair using an EndoButton technique results in excellent patient reported outcomes and health-related quality of life. Although rare, unrecovered nerve injury adversely affects outcome

Upper limb amputations, ranging from transhumeral to partial hand, can be devastating for patients, their families, and society. Modern paradigm shifts have focused on reconstructive options after upper extremity limb loss, rather than considering the amputation an ablative procedure. Surgical advancements such as targeted muscle reinnervation and regenerative peripheral nerve interface, in combination with technological development of modern prosthetics, have expanded options for patients after amputation. In the near future, advances such as osseointegration, implantable myoelectric sensors, and implantable nerve cuffs may become more widely used and may expand the options for prosthetic integration, myoelectric signal detection, and restoration of sensation. This review summarizes the current advancements in surgical techniques and prosthetics for upper limb amputees.

Management of the pathologic long-head biceps tendon remains controversial. Biceps tenotomy is a simple intervention but may result in visible deformity and subjective cramping. Comparatively, biceps tenodesis is technically challenging, and has increased operative times, and a more prolonged recovery. The purpose of this study was to determine the incidence of popeye deformity following biceps tenotomy versus tenodesis, identify predictors for developing a deformity, and compare subjective and objective outcomes between those that have one and those that do not. Data for this study were collected as part of a randomized clinical trial comparing tenodesis versus tenotomy in the treatment of lesions of the long head of biceps tendon. Patients 18 years of age or older with an arthroscopy confirmed biceps lesion were randomized to one of these two techniques. The primary outcome measure for this sub-study was the rate of a popeye deformity at 24-months post-operative as determined by an evaluator blinded to group allocation. Secondary outcomes were patient reported presence/absence of a popeye deformity, satisfaction with the appearance of their arm, as well as pain and cramping on a VAS. Isometric elbow flexion and supination strength were also measured. Interrater reliability (Cohen's kappa) was calculated between patient and evaluator on the presence of a deformity, and logistic regression was used to identify predictors of its occurrence. Linear regression was performed to identify if age, gender, or BMI were predictive of satisfaction in appearance if a deformity was present. Fifty-six participants were randomly assigned to each group of which 42 in the tenodesis group and 45 in the tenotomy group completed a 24-month follow-up. The incidence of popeye deformity was 9.5% (4/42) in the tenodesis group and 33% (15/45) in the tenotomy group (18 male, 1 female) with a relative risk of 3.5 (p=0.016). There was strong interrater agreement between evaluator and patient perceived deformity (kappa=0.636; p<0.001). Gender tended towards being a significant predictor of having a popeye with males having 6.6 greater odds (p=0.090). BMI also tended towards significance with lower BMI predictive of popeye deformity (OR 1.21; p=0.051). Age was not predictive (p=0.191). Mean (SD) satisfaction score regarding the appearance of their popeye deformity was 7.3 (2.6). Age was a significant predictor, with lower age associated with decreased satisfaction (F=14.951, adjusted r2=0.582, p=0.004), but there was no association with gender (p=0.083) or BMI (p=0.949). There were no differences in pain, cramping, or strength between those who had a popeye deformity and those who did not. The risk of developing a popeye deformity was 3.5 times higher after tenotomy compared to tenodesis. Male gender and lower BMI tended towards being predictive of having a deformity; however, those with a high BMI may have had popeye deformities that were not as visually apparent to an examiner as those with a lower BMI. Younger patients were significantly less satisfied with a deformity despite no difference in functional outcomes at 24 months. Thus, biceps tenodesis may be favored in younger patients with low BMI to mitigate the risk of an unsatisfactory popeye deformity

Aims

It has been hypothesized that proximal radial neck resorption (PRNR) following press-fit radial head arthroplasty (RHA) is due to stress-shielding. We compared two different press-fit stems by means of radiographs to investigate whether the shape and size of the stems are correlated with the degree of PRNR.

Aims

Brachial plexus injury (BPI) is an often devastating injury that affects patients physically and emotionally. The vast majority of the published literature is based on surgeon-graded assessment of motor outcomes, but the patient experience after BPI is not well understood. Our aim was to better understand overall life satisfaction after BPI, with the goal of identifying areas that can be addressed in future delivery of care.
