Supracondylar fractures of the humerus (SCH) are the most common fractures sustained following a fall on an outstretched hand in healthy children, and one of the leading causes of hospital admission and surgical intervention. With increasing severity of injury, treatment options become more invasive and the potential for long lasting complications increases. The aim of this study is to examine the causes and circumstances surrounding SCH in public play spaces particularly to determine whether or not the playground equipment implicated in injurious falls is compliant with Canadian Standards Association (CSA) standards.

Children aged 6–12 years who sustained SCH while playing at a public play space between 2017 and 2019 were recruited from the paediatric orthopaedic clinic. Public playgrounds within a 50 km radius of the clinic were visited by research assistants. Using GPS coordinates from photographs taken by the children at the site of injury or play structures identified by the children using Google Maps, play structure type, dimensions, height of fall, and the type and depth of the surface material were collected from each site and compared to the relevant CSA standard.

Of the 89 SCH injuries reported during the recruitment period, 49 (55%) occurred on public play structures. Thirty-nine injury sites, representing 42 SCH cases, were accessible to conduct site visits and were included in the analysis. Thirteen children (31%) sustained Type One, 19 (45%) were Type Two, and 10 (24%) were Type Three SCHs. The mean child age at injury was 7.13 years. Of the 42 SCH cases, 37 sites had woodchips surfacing (88%); three had rubber (7%), one had cement (2%), and one had sand (2%). Of the 36 sites where woodchip depth measurements could be obtained, only seven (19%) met the minimum CSA depth. Out of the 42 SCH cases, 29 injuries (69%) involved upper body equipment (i.e. monkey bars or similar) and track rides. Fourteen of these 29 injuries (48%) occurred on structures that did not meet CSA standards for fall height. All rotating play structures had less than half of the required clearance between the components.

Eighty-six percent of SCH cases occurred in playgrounds where at least one of the required CSA standards was not met. Woodchip surfacing was of particular concern because 81% of woodchip surface depths failed to meet CSA standards. Of the 14 injuries where fall height did not meet CSA standards, 11 (79%) also did not meet minimum CSA surface depth. Field investigation into the characteristics of playgrounds in which children sustain SCH can guide preventative policy and practice measures. Municipalities and school boards should be alerted to the need for regular maintenance of woodchip playground surfacing, in order to remain compliant with the minimum surface depth and prevent serious injuries. Additionally, compliance with minimum surface depths can also decrease fall heights to meet CSA standards. By minimizing the prevalence of SCH injuries occurring on play structures and the need for emergency department visits, the burden to healthcare systems and families of injured children can potentially be reduced.

Introduction and objective: Distal biceps tendon ruptures commonly occur in the dominant arm of male between 40 and 60 years of age. The degenerative tendon avulses from the radial tuberosity. Conservative treatment results in decreased flexion and supination strength. Surgical reattachment is the treatment of choice and several surgical approaches and fixation devices have been proposed. The purpose of this study was to compare the results of two different techniques.

Materials and Methods: Twenty-four consecutive patients with distal biceps tendon ruptures were randomly assigned to one of two treatment groups: 12 using 2 biodegradable anchors through a modified 2-incision technique (group A) and 12 patients underwent distal biceps repair using an Endobutton^® (Acufex Smith & Nephew, Andover MA) using a single transverse anterior incision (group B). All patients were male. Average age was 40 (33–57) in groupA and 42 (29–59) in group B. The rupture was located in the dominant arm in 6 patients in groupA and 7 in group B.

The interval between injury and surgery was similar in both groups (< 12 days). Postoperative protocol and rehabilitation was the same in both groups. Full range of motion as tolerated was allowed two week after surgery.

Active range of motion, Mayo Elbow Performance Score (MEPS), pain, strength (Dexter isokinetic testing), patient satisfaction, operative time and elbow radiographs were evaluated at 12 months postoperatively. The mean follow-up was 17 months (range, 12–34).

Results: Average operative time (minutes):50 (group A) and 42 (group B). There were no complications in group B. Two patients in group A had a transient posterior interosseous nerve neurapraxia with spontaneous full recovery after 3 months, and other one developed symptomatic heterotopic bone formation and synostosis was resected. There was no statistical significant difference in MEPS score, range of motion, time to return to work or strength between both groups. All patients in both groups were satisfied with their final result and eventually returned to their pre-injury activity level without sequelae after 12.2 (group A) and 10.3 (group B) weeks.

Conclusion: Functional results of the two techniques studied were similar. Anterior approach showed lesser complications and less time off work than 2-incision technique. Endobutton^® single approach assisted tecnique should be considered the gold standard procedure for distal biceps tendon repair due to its shorter operative time and lower morbidity. However, we need series with a longer follow-up to confirm these results.

Aim: To assess the functional and occupational outcome of open elbow arthrolysis for post-traumatic contractures.

Materials and Methods: Prospective evaluation of 60 consecutive cases (86% male,14%female) of post-traumatic extrinsic elbow stiffness. Average age was 37 years (24–48). Moderate to high physical demand at work in 96% of cases. 56% of cases involved the right side.

Open arthrolysis (column procedure) trough a lateral (72%) or posterior (28%) approach followed a minimum rehabilitation period of 6 months post original injury. In 8 cases, an anterior transposition of the ulnar nerve was required. Patients received postoperative analgesia with Bupivacaine 0,0125% trough an indwelling catheter. No chemical or radiotherapy ectopic calcification prophylaxis was used. Postoperative complications, range of motion, X-ray evaluation, time to return to work, activity level and workers’ compensation were evaluated at the end of follow-up (24 months, range 12–36).

Results: Complications occurred in 14% of cases. Two patients required revision surgery for ectopic calcifications restricting prono-supination. The flexo-extension (FE) arc of motion improved from 49 ° to 115 ° and that of prono-supination (PS) from 100 ° to 158 ° The results were found to be statistically significant for FE (p= 0.054) and PS (p> 0,00001).

In 20% of cases, patients returned to their previous job with some restrictions (33% disability) and 12% changed to a less physically demanding occupation.

Conclusions: Open arthrolysis is an effective surgical procedure to improve mobility in post-traumatic stiff elbows. It is indicated when the joint interline is preserved. Good functional and occupational outcome in a high percentage of case in the working population was observed.

Objective: The purpose of this study was to determine which factors may influence in the outcome of the surgical treatment of Carpal Tunnel Syndrome (CTS).

Material and Methods: During 2005, 175 patients were treated with the diagnosis of CTS by open carpal release (short palmar incision) without ligament reconstruction. 113 cases were selected: 39 males and 74 females, with an average age of 41 years (21 to 64 years) and a follow-up of 24 months (12–36 months). The dominant hand was treated in 58%. The subcutaneous cellular tissue (SCT) was sutured in 14% and 11% were immobilized with a cast for 2 weeks after surgery.

We considered factors such as: systemic conditions, functional work requirement, preoperative time, surgical technique, and their correlation with complications, clinical outcome and time to return to work and activity level.

Results: Complications: 41% pillar pain, 9% suture dehiscence, 3,5% ulnar neuritis, 1,7% trigger finger, 1,7% reflex sympathetic dystrophy, and 1,8% wound infection. 5 patients were re-operated. Complications rate due to surgery was 3,5% after 12 months of follow-up. The average time out of work was 9 weeks (2–43 weeks) and was higher (13 weeks) in patients with post-operative immobilization. All patients, except one, returned to their previous activity level. History of systemic conditions and dominance had not influence on the final outcome. The suture of the SCT and the postoperative immobilization showed lower wound dehiscence and pillar pain cases.

Conclusions: The surgical treatment of the CTS provides good clinical and labour results. Patients with suture of the SCT and cast immobilization show less post-operative surgical complications.

Objective: The purpose of this study was to compare the functional and workers compensation results of displaced intra-articular distal radius fractures treated with three diferent type of treatments.

Material and Methods: A randomized prospective study to evaluate 70 patients with displaced intraarticular distal radius fractures. The mean age were 40 years (range, 22–65 years) and all patients were medium or high level workers (40% dominant-hand). Three randomized groups were treated: 19 patients with close reduction and a cast (group 1); 24 patients with close reduction, percutaneous fixation with Kw and a cast (group 2); and 27 patiens with close reduction and external fixation and Kw (group 3).

Postoperative complications, pain (visual analogue scale), clinical and functional outcome based on DASH score, grip strength, X-ray evaluation, time to return to work and activity level were evaluated and compared at 3, 6 and 12 months of prospective follow-up.

Results: Consolidation was obtained in all cases at 7 weeks. Results at 12 months of follow-up: Pain evaluation score: 2.3 (group 1), 2.9 (group 2) and 1.5 (group 3); mean lost of ROM was 11° (group 1), 11° (group 2) and 23.9° (group 3); mean DASH score was 7 (group 1), 29 (group 2) and 12 (group 3). Average lost of pinch strength was 18.3% (group 1), 23% (group 2) and 35% (group 3). Non-aceptable X-ray parameters: 65% (group 1), 35% (group 2) and 50% (group 3).

Re-operations: 10% (group 1), 7.6% (group 2) and 14.8% (group 3). The average time to return to work (weeks) was 12 (group 1), 14 (group 2) and 19.3 (group 3). All patients return to the work and activity level they had before injury.

Conclusions: Similar results were obtained in the three groups at 12 months but better clinical results for the conservative group (group 1) at 3 and 6 months of FU. The orthopaedic treatment achieved better functional results with lesser lost of ROM, time out of work, more grip strength and better DASH score. Percutaneous fixation achieve better X-ray results at the end of FU with lesser re-operations. The functional and clinical outcomes after one year still are unknown. Hence, more and longer studies are required to confirm these results.

Aim: Total Wrist fusion is the main procedure for treatment of postraumatic and degenerative wrist osteoarthritis. During the last decade, midcarpal fusion has become more and more popular as it preserves motion. The purpose of this study was to compare the functional and workers compensation results of both treatments on active workers.

Material and Methods: A prospective study to evaluate 77 patients (76 male and 1 female) who underwent wrist fusion, between 2002 to 2006, with an average of 28 months of follow-up (range, 12–58 months) were made. The mean age were 32 years (range, 25–48 years) and all patients were medium or high level workers with postraumatic and degenerative wrist osteoarthritis. The aethiology in 67% of the patients was SNAC wrist. Right hand was involved in 65% of the patients.

Thirty-eight patients were treated with scaphoid excision and 4-corner fusion using dorsal circular plate. Thirty-nine patients were treated with total wrist fusion using one single, dorsal, precontoured and tapered plate for osteosynthesis and third carpometacarpal joint (CMCJ-3) was included. All patients were immobilised in a cast for 4 weeks after surgery.

Postoperative complications, pain (visual analogue scale), clinical and functional outcome based on Green and O’Brien score, grip strength, X-ray evaluation, time to return to work and activity level were evaluated and compared.

Results: Consolidation was obtained in all cases at 10 weeks. Pain evaluation score was 19,2 (4-corner) and 13,8 (total fusion) on post-op time. The mean modified Mayo wrist score was 70,4 (4-corner) and 69 (total wrist). Average lost of pinch strength was 43% (4corner) and 21% (total fusion). 2 patients with 4-corner fusion required total wrist arthrodesis. Three cases who had a total wrist fusion, required implant removal.

The average time to return to work was 17 weeks (4-corner) and 16,2 weeks (total fusion). All patients return to work. Twelve percent of four-corner fusion and 72% of total wrist fusion return to the same work level with restrictions (until 33% of activity). Twenty-two percent of 4-corner fusion and 28% of total wrist fusion were unable to return to their previous activity level, performing lower intensity work activities. Overall satisfaction was high in both groups with 85% (4corner) and 93% (total fusion).

Conclusion: Both fusion techniques allows an effective stabilization, maintaining the bone stock and eliminate wrist pain with fast return to work.

Total wrist fusion had less surgical failures, better level of satisfaction, lesser lost of force than 4-corner fusion, with less potential for further deterioration with time. However, 4-corner fusion allows return to work with a similar activity level and preserve a functional range of motion in patients with high levels of activity.

Introduction: Intraarticular fractures of distal radius are associated with high energy mechanisms, are severe and difficult to obtain a surgical reduction. The aim of our paper is to compare the clinical, radiographically and activity results in workers treated with surgical and conservative procedures.

MATERIAL AND METHODS: A prospective study was organized in 43 heavy-labour workers (34 male and 9 female) with unstable fractures of distal radius, treated between 2003 and 2005. The minimal follow-up was of one year. The mean age were 40 years (22–65 years) and dominant limb was involved in 40% of the cases. To treatment groups were established. Group 1, conservative treated with indirect reduction and cast immobilization (n=20) and Group 2 surgically treated with indirect reduction and percutaneous fixation with K-wires and cast immobilization (n=24).

Pain, mobility and radiograhs were evaluated and also strength (isokinetics), functionality (DASH score) and, finally, the return to work at 3, 6 and 12 months.

RESULTS: Fracture healing was obtained at 7 weeks but the time to return to work were 14 weeks after surgery. Pain score, at 12 months, were 2,3 points for conservative treatment and 2,9 points for the surgically group. The flexion – extension mobility loss, in relation to the contralateral wrist, was lesser in the conservative group at 3 and 6 month but similar (11°) at 12 months in both groups. Radiographs corrections were anatomically in 38% of the cases of group 1 and in 80% of group 2. Functional and strength results were similar in both groups. All the patients return to the same work activity.

CONCLUSIONS: Percutaneous fixation of unstable intraarticular distal radius fracture is comparable to the conservative treatment but the percentage of anatomical reductions was higher. It would be of importance in the evolution of the patients.

AIM: We present the results of scaphoid non-unions treated with open reduction, bone grafting and internal fixation with biodegradable implants on active heavy labour workers.

MATERIAL AND METHODS: Between 2002 to 2004, 20 patients with scaphoid non-unions were treated by open reduction, bone grafting and internal fixation using self-reinforced poly-L-lactic acid screws. The mean prospective follow-up was 24 months (range, 12–38 months). The mean age was 28 years (range, 18–42 years). All patients were male and heavy-labour workers.

The patients were assessed clinically (modified Mayo wrist score) and radiograhically. The grip and pinch strength were also studied.

RESULTS: We find 13 excellent results, good in 5 cases and poor in 2 cases. A Matti-Russe group patient was revised 6 months after the first intervention. Any fragment displacement, implant loosening or adverse reaction was found. Most of the patients (90%) return to the same work and the same level without complications.

CONCLUSION: Both groups are a good alternative for the scaphoid non-unions treatment. However, biodegradable implants disappears in the time, the removal are no necessary, facilitate the revision surgery, if necessary, and permitted MRI studies to evaluated the graft viability.
