Abstract. Objective. Radial to axillary nerve and spinal accessory (XI) to suprascapular nerve (SSN) transfers are standard procedures to restore function after C5 brachial plexus dysfunction. The anterior approach to the SSN may miss concomitant pathology at the suprascapular notch and sacrifices lateral trapezius function, resulting in poor restoration of shoulder external rotation. A posterior approach allows decompression and visualisation of the SSN at the notch and distal coaptation of the medial XI branch. The medial triceps has a double fascicle structure that may be coapted to both the anterior and posterior division of the axillary nerve, whilst preserving the stabilising effect of the long head of triceps at the glenohumeral joint. Reinnervation of two shoulder abductors and two external rotators may confer advantages over previous approaches with improved external rotation range of motion and strength. Methods. Review of the clinical outcomes of 22 patients who underwent a double nerve transfer from XI and radial nerves. Motor strength was evaluated using the MRC scale and grade 4 was defined as the threshold for success. Results. 18/22 patients had adequate follow-up (Mean: 29.5 months). Of these, 72.2% achieved ≥grade 4 power of shoulder abduction and a mean range of motion of 103°. 64.7% achieved ≥grade 4 external rotation with a mean range of motion of 99.6°. Conclusions. The results suggest the use of the combined nerve transfer for restoration of shoulder function via a posterior approach, involving the medial head branch of triceps to the axillary nerve and the XI to SSN

Aim. To assess clinical outcome of massive rotator cuff tear repair using triceps myotendinous flap. Method. This is a prospective cohort of 43 patients (24 male, 19 female) with average age of 62 years. The primary indication of surgery was pain. Patients with massive rotator cuff tear involving supraspinatus and infraspinatus, showing retraction and fatty infiltration in MRI were selected. Few (8/43) were with failed surgical treatment and rest had conservative treatment failed. They underwent rotator cuff repair during Feb 1999 to Jan 2004. The long head of the triceps was detached from the olecranon, rotated 180 degrees from its pivot point with its major vascular pedicle under the deltoid and acromion through the posterior capsule and attached to the greater tuberosity and any remnant of remaining cuff. All patients were assessed pre-operatively, at 3, 6 and 12 months post-operatively clinically and also using UCLA pain and functional score for shoulder. Shoulder range of motion was assessed before and after the surgery. 24 patients had minimum of 1 year and 19 had 2 year minimum follow-up. Results. The mean total UCLA score of 9.7 pre-operatively improved to 27.8 (p<0.0001) following the operation. The mean pre-operative UCLA pain score 2.2 improved to 7.8 post-operatively (p<0.001). The UCLA functional score improved from a pre-operative average of 3.4 to 8.2 (p<0.0001) following the operation. There was significant improvement in forward elevation, external and internal rotation but not abduction. There was no weakness in elbow extension. Complications: 3 superficial infections, 1 ulnar neuritis (resolved in 6 weeks), 1 olecranon bursitis (resolved in 3 months). Conclusion. Long head triceps tendon transfer is an effective technique to alleviate pain and improve functions in patients with massive rotator cuff tear, specially in difficult group of patients with limited options

Intraarticular fractures of the distal humerus comprise 1% of all fractures in adults. Triceps reflecting and olecranon osteotomy approach provide adequate exposure in intraarticular fracture with its own advantage and disadvantages. Forty consecutive patients with fractures of the distal humerus were treated over a 36-month period. The patients were randomly allotted into two groups; group A consists of twenty patients with olecranon osteotomy and group B consists of twenty patients with triceps reflecting approach. In both the groups fracture was fixed using orthogonal or parallel plating techniques. Clinical outcome was assessed using the DASH SCORE, radiological union and complications was noted in both the group and compared. In group A the mean DASH score was 15.9 points. Three patients underwent a second procedure for hardware removal, 2 patients had non-union at osteotomy site, one patient had transient ulna nerve neuropraxia and one patient had superficial infection. In group B the mean DASH score was 14 points. There was no statistical significance between both groups regarding final outcome except complications were more in osteotomy approach. We conclude both approach is an effective procedure with an excellent or good functional outcome but osteotomy approach has more complications

Adequate exposure is a prerequisite for treatment of distal humeral fractures. In this study, we compared the clinico-radiological and functional outcome of TRAP approach with that of olecranon osteotomy for distal humerus fractures. 27 patients with distal humerus fractures were randomized into 2 groups: Group 1 (n=14, TRAP approach), Group 2 (n=13, Olecranon osteotomy). All patients were operated with bi-columnar fixation. All patients were mobilized from day 2. Follow-up evaluation was done at 1, 3, 6 and 12 months. All patients achieved union. The mean surgical time was higher in group 1 (120 min) as compared to group 2 (100 min). The final ROM was higher in group 1 (1160) as compared to group 2 (850). Two patients in group 2 needed posterior release. 5 patients in group 2 had hardware complications related to olecranon osteotomy and needed removal. Two patients in Group 1 had transient ulnar nerve paraesthesias. There was no difference in triceps power in both groups. Our results demonstrate that TRAP approach is extensile and safe enough in treating these complex fractures with better final ROM and fewer complications

Introduction

The gastrocnemius tendon extends from the musculotendinous junction proximally to the conjoint junction with soleus distally. The morphology of the junction has not, to our knowledge, been described previously. Lengthening of the gastrocnemius tendon is a standard surgical procedure in surgery for cerebral palsy. The aims of the study were to describe the morphology of the conjoint junction and to identify the location of the gastrocnemius tendon relative to palpable bony landmarks to assist with incision planning.

Acromial morphology has been implicated as a risk factor for unidirectional posterior shoulder instability. Studies utilising plain film radiographic landmarks have identified an increased risk of posterior shoulder dislocation in patients with higher acromion positioning. The aims of this study were to develop a reproducible method of measuring this relationship on cross sectional imaging and to evaluate acromial morphology in patients with and without unidirectional posterior shoulder instability. We analysed 24 patients with unidirectional posterior instability. These were sex and age matched with 61 patients with unidirectional anterior instability, as well as a control group of 76 patients with no instability. Sagittal T1 weighted MRI sequences were used to measure posterior acromial height relative to the scapular body axis (SBA) and long head of triceps insertion axis (LTI). Two observers measured each method for inter-observer reliability, and the intraclass correlation coefficient (ICC) calculated. LTI method showed good inter-observer reliability with an ICC of 0.79. The SBA method was not reproducible due suboptimal MRI sequences. Mean posterior acromial height was significantly greater in the posterior instability group (14.2mm) compared to the anterior instability group (7.7mm, p=0.0002) as well when compared with the control group (7.0mm, p<0.0001). A threshold of 7.5mm demonstrated a significant increase in the incidence of posterior shoulder instability (RR = 9.4). We conclude that increased posterior acromial height is significantly associated with posterior shoulder instability. This suggests that the acromion has a role as an osseous restraint to posterior shoulder instability

Olecranon fractures are common injuries representing roughly 5% of pediatric elbow fractures. The traditional surgical management is open reduction and internal fixation with a tension band technique where the pins are buried under the skin and tamped into the triceps. We have used a modification of this technique, where the pins have been left out of the skin to be removed in clinic. The purpose of the current study is to compare the outcomes of surgically treated olecranon fractures using a tension-band technique with buried k-wires (PINS IN) versus percutaneous k-wires (PINS OUT). We performed a retrospective chart review on all pediatric patients (18 years of age or less) with olecranon fractures that were surgically treated at a pediatric academic center between 2015 to present. Fractures were identified using ICD-10 codes and manually identified for those with an isolated olecranon fracture. Patients were excluded if they had polytrauma, metabolic bone disease, were treated non-op or if a non-tension band technique was used (ex: plate/screws). Patients were then divided into 2 groups, olecranon fractures using a tension-band technique with buried k-wires (PINS IN) and with percutaneous k-wires (PINS OUT). In the PINS OUT group, the k-wires were removed in clinic at the surgeon's discretion once adequate fracture healing was identified. The 2 groups were then compared for demographics, time to mobilization, fracture healing, complications and return to OR. A total of 35 patients met inclusion criteria. There were 28 patients in the PINS IN group with an average age of 12.8 years, of which 82% male and 43% fractured their right olecranon. There were 7 patients in the PINS OUT group with an average age of 12.6 years, of which 57% were male and 43% fractured their right olecranon. All patients in both groups were treated with open reduction internal fixation with a tension band-technique. In the PINS IN group, 64% were treated with 2.0 k-wires and various materials for the tension band (82% suture, 18% cerclage wire). In the PINS OUT group, 71% were treated with 2.0 k-wires and all were treated with sutures for the tension band. The PINS IN group were faster to mobilize (3.4 weeks (range 2-5 weeks) vs 5 weeks (range 4-7 weeks) p=0.01) but had a significantly higher complications rate compared to the PINS OUT group (6 vs 0, p =0.0001) and a significantly higher return to OR (71% vs 0%, p=0.0001), mainly for hardware irritation or limited range of motion. All fractures healed in both groups within 7 weeks. Pediatric olecranon fractures treated with a suture tension-band technique and k-wires left percutaneously is a safe and alternative technique compared to the traditional buried k-wires technique. The PINS OUT technique, although needing longer immobilization, could lead to less complications and decreased return to the OR due to irritation and limited ROM

Introduction. Although Total elbow arthroplasty (TEA) generally provides favorable clinical outcomes, its complications have been reported with high rate compared with other joints. Previously, we used the Bryan & Morrey approach in TEA, which included separating the triceps muscle subperiosteally from the olecranon; however, since 2008, in order to prevent skin trouble and deficiency of the triceps, we performed TEA by MISTEA method, which required no removal of the subcutaneous tissue in the region of the olecranon and no release or stripping of the triceps tendon. Objectives. The purpose of this study was to examine the utility of the MISTEA method by evaluating and comparing muscle strength and complications by using both the Bryan & Morrey approach and MISTEA method. Materials and Methods. The study was conducted on 23 elbows, on which elbow muscle strength could be measured postoperatively at more than 6 months after TEA. Thirteen elbows were operated on the Bryan & Morrey approach (BM group; mean age, 62.3 years; mean follow-up period, 27 months), and 10 elbows on the MISTEA method (MIS group; mean age, 67.6 years; mean follow-up period, 19.1 months). To determine the elbow extensor and flexor strengths, measurements were conducted on the affected side for the BM group, and on both the affected and healthy sides for the MIS group. Further, the “extension/flexion ratio” as well as the “affected/healthy side ratio” and complications were assessed. Results. Excluding the elbow extensor strength of 3 elbows in the BM group, which could not be measured too week. The extension/flexion ratio was as follows: in the BM group, 0.61 and in the MIS group, 0.93 on the affected side and 0.81 on the healthy side. For the MIS group, in which measurements could be performed on both the sides, the “affected/healthy side ratio” was 0.72 in flexion and 0.91 in extension. In terms of complications, skin trouble was found on 2 elbows in the BM group and on 1 elbow in the MIS group; further, rupture of the triceps tendon was suspected in 3 elbows in the BM group but was not found in the MIS group. Discussion. In our study, deficiency in triceps muscle was found in 3 of 13 elbows with the Bryan & Morrey approach. MISTEA method may be the reason for prevention of deficiency or rupture of the triceps tendon. The MIS group had higher extension/flexion ratio in the affected side, suggesting the possibility that either the extensor strength had increased or the flexor strength had weakened. Further, in the MIS group, the extension showed an “affected/healthy side” ratio, which means that an extensor strength almost equivalent to that of the healthy side was maintained, whereas the flexor strength was 72% of that on the healthy side, suggesting that the flexor strength may have decreased. Loss of the flexor strength may be because the MISTEA method involves partial release of the brachialis muscle and the joint's center of rotation to move slightly towards the proximal side

Aim. Reconstruction of composite soft-tissue defects with extensor apparatus deficiency in patients with periprosthetic joint infection (PJI) of the knee is challenging. We present a single-centre multidisciplinary orthoplastic treatment concept based on a retrospective outcome analysis over 20 years. Method. One-hundred sixty-seven patients had PJI after total knee arthroplasty. Plastic surgical reconstruction of a concomitant perigenicular soft-tissue defect was indicated in 49 patients. Of these, seven presented with extensor apparatus deficiency. Results. One patient underwent primary arthrodesis and six patients underwent autologous reconstruction of the extensor apparatus. The principle to reconstruct missing tissue ‘like with like’ was thereby favoured: Two patients with a wide soft-tissue defect received a free anterolateral thigh flap with fascia lata; one patient with a smaller soft-tissue defect received a free sensate, extended lateral arm flap with triceps tendon; and three patients received a pedicled medial sural artery perforator gastrocnemius flap, of which one with Achilles tendon. Despite good functional results 1 year later, long-term follow-up revealed that two patients had to undergo knee arthrodesis because of recurrent infection and one patient was lost to follow-up. In parts, results have been published under doi: 10.7150/jbji.47018. Conclusions. A treatment concept and its rationale, based on a single-centre experience, is presented. It differentiates between various types of soft-tissue defects and shows reconstructive options following the concept to reconstruct ‘like with like’. Despite good results 1 year postoperatively, PJI of the knee with extensor apparatus deficiency remains a dreaded combination with a poor long-term outcome

Estrogen fluctuations have been implicated in the soft tissue injury gender-bias due to the hormones effect on the viscoelastic properties. The isolated effect of estrogen on the mechanical behaviour of human tendon is unknown. The purpose of this study was to elucidate the effect of circulating levels of estrogen on the strain properties of the human Achilles tendon. Twenty females (18–35 years) who were using the pill together with 20 matched, non-pill users, participated in this study. Non-pill users were tested at the time of lowest (menstruation) and highest (ovulation) estrogen whilst pill users, who exhibited constant and attenuated estrogen levels, were tested at menstruation and two weeks later. At each test session, maximal isometric plantarflexion efforts were performed on a calf-raise apparatus whilst synchronous real-time ultrasonography of the triceps surae aponeurosis was recorded. Connective tissue length (Lo) of the triceps surae complex was measured and tendon strain was calculated by dividing aponeurosis displacement during plantarflexion by Lo. Repeated measures ANOVA revealed a significant (p < 0.05) main effect of subject group with significantly higher Achilles strain rates (16.1%) in the non-pill users compared to the pill users. Augmented Achilles tendon strain was associated with higher average estrogen levels in non-pill users. Those results suggest that higher estrogen levels diminish the joint stabilising capacity of the triceps surae musculotendinous unit and may alter the energy storage capacity of the Achilles tendon during stretch-shorten cycle activities. This may result in a higher incidence of injuries during periods of high estrogen concentration

We report the case of a 12-year-old boy with flexion loss in the left elbow caused by deficient of the concavity corresponding to the coronoid fossa in the distal humerus. The range of motion (ROM) was 15°/100°, and pain was induced by passive terminal flexion. Plain radiographs revealed complete epiphyseal closure, and computed tomography (CT) revealed a flat anterior surface of the distal humerus; the coronoid fossa was absent. Then, the bony morphometric contour was surgically recreated using a navigation system and a three-dimensional elbow joint model. A three-dimensional model of the elbow joint was made preoperatively and the model comprising the distal humerus was milled so that elbow flexion flexion of more than 140° could be achieved against the proximal ulna and radius. Navigation-assisted surgery (contouring arthroplasty) was performed using CT data from this milled three-dimensional model. Subsequently, an intraoperative passive elbow flexion of 135° was obtained. However, active elbow flexion was still inadequate one year after operation, and a triceps lengthening procedure was performed. At the final follow-up one year after triceps lengthening, a considerable improvement in flexion was observed with a ROM of −12°/125°. Plain radiographs revealed no signs of degenerative change, and CT revealed the formation of the radial and coronoid fossae on the anterior surface of the distal humerus. Navigation-assisted surgery for deformity of the distal humerus based on a contoured three-dimensional model is extremely effective as it facilitates evaluation of the bony morphometry of the distal humerus. It is particularly useful as an indicator for milling the actual bone when a model of the mirror image of the unaffected side cannot be applied to the affected side as observed in our case

Avulsion fractures of the tip of the olecranon are a common traumatic injury. Kirshner-wire fixation (1.6mm) with a figure of eight tension band wire (1.25mm) remains the most popular technique. Hardware removal mat be required in up to 80% of cases. Modern suture materials have very high tensile strength coupled with excellent usability. In this study we compare a repair using 1.6mm k-wires with a 1.25mm surgical steel, against a repair that uses two strands of 2 fibrewire. Twelve Pairs of cadaveric arms were harvested. A standard olecranon osteotomy was performed to mimic an avulsion fracture. In each pair one was fixed using standard technique, 2 × 1.6mm transcortical ?-wire plus figure of 8 loop of 1.25mm wire. The other fixed with the same ?-wires with a tension band suture of 2.0 fibrewire (two loops, one figure of 8 and one simple loop). The triceps tendon was cyclically loaded (10-120 Newtons) to simulate full active motion 2200 cycles. Fracture gap was measured with the ‘Smart Capture’ motion analysis system. The arm was fixed at 90 degrees and triceps tendon was loaded until fixation failure, ultimate load to failure and mode of failure was noted. The average gap formation at the fracture site for the suture group was 0.91mm, in the wire group 0.96mm, no specimen in either group produced a significant gap after cyclical loading. Mean load to failure for the suture group was 1069 Newtons (SD=120N) and in the wire group 820 Newtons (SD=235N). Both types of fixation allow full early mobilisation without gap formation. The Suture group has a significantly higher load to failure (p=0.002, t-test). Tension Band suture allows a lower profile fixation, potentially reducing the frequency of wound complications and hardware removal

Aims. Compression and absolute stability are important in intra-articular fractures such as transverse olecranon fractures. This biomechanical study aims to compare tension band wiring (TBW) with plate fixation by measuring compression within the fracture. Methods. A cross-over design and synthetic ulna models were used to reduce variation between samples. Identical transverse fractures were created using a 0.5mm saw blade and cutting jig. A Tekscan(tm) force transducer was calibrated and placed within the fracture gap. Twenty TBW or Acumed(tm) plate fixations were performed according to the recommended technique. Compression was measured while the constructs were static and during simulated elbow range of movement exercises. Dynamic testing was performed using a custom jig reproducing cyclical triceps contraction of 20N and reciprocal brachialis contraction of 10N. Both fixation methods were tested on each sample. Half were randomly allocated to TBW first and half to plating first. Data was recorded using F-scan (v 5.72) and analysed using SPSS(tm) (v 16). Paired T-tests compared overall compression and compression at the articular side of the fracture. Results. The mean overall compression for plating was 819N (+/− 602N 95%CI), TBW overall compression: 77N (+/−19N 95%CI) (P=0.039). Articular side compression for plating: 343N (+/− 276N 95%CI), TBW: 1N (+/− 2N 95%CI). (P=0.038). During simulated movements, overall compression reduced in both groups: TBW -14N (+/−7N) Plating -173N (+/−32N) and no increase in articular side compression was detected in the TBW group. Conclusion. Precontoured plates such as the Acumed(tm) olecranon system can provide significantly greater compression, compared to TBW in transverse olecranon fractures. This was significant for compression over the whole fracture surface and specifically at the articular side of the fracture. Also, in TBW, overall compression reduced and articular side compression remained negligible during simulated triceps contraction, challenging the tension band principle

This study reviews the early results of Distal Humeral Hemiarthroplasty(DHH) for distal humeral fracture and proposed a treatment algorithm incorporating the use of this technique in the overall management of distal humeral fractures. DHH was performed on 30 patients (mean 65 years; 29-91) for unreconstructable fractures of the distal humerus or salvage of failed internal fixation. A triceps on approach was used in six and an olecranon osteotomy in 24. A Sorbie Questor prosthesis (Wright Medical Technology) was used in 14 patients and a Latitude (Tornier) in 16. Clinical review at a mean of 25 months (3–88) included the American Shoulder and Elbow Surgeons elbow outcomes instrument (ASES), Mayo Elbow Performance Index (MEPI) and radiological assessment. At follow up of 28 patients mean flexion deformity was 25 degrees, flexion 128 degrees, range of pronosupination 165 degrees, mean ASES 83, MEPI 77 and satisfaction 8/10. Acute cases scored better than salvage cases. Re- operation was required in 16 patients (53%); two revisions to a linked prosthesis for periprosthetic fracture and aseptic loosening at 53 and 16 months, 12 metalwork removals and four ulnar nerve procedures. Posterolateral rotatory instability was present in one elbow, four had laxity and mild pain on loading (two with prosthesis or pin loosening), four had laxity associated with column fractures (two symptomatic) and 10 had asymptomatic mild laxity only. The triceps on approach had worse instability and clinical scores. Uncomplicated union occurred in all olecranon osteotomies and 86% of column fractures. One elbow had an incomplete cement mantle and seven had lucencies >1 mm; one was loose but acceptable. Five prostheses were in slight varus. Two elbows had early degenerative changes and 15 developed a medial spur on the trochlea. This is the largest reported experience of DHH. Early results of DHH show good outcomes after complex distal humeral fractures, despite a technically demanding procedure. Better results are obtained for treatment in the acute setting and with use of an olecranon osteotomy. As a result of this experience anatomical and clinical pre-requisites and advise on technique are outlined. An algorithm for use of DHH in relation to total elbow arthroplasty and ORIF for the treatment of complex intra-articular distal humeral fractures with or without column fractures is proposed

Fracture or resection of the radial head can cause unbalance and long-term functional complications in the elbow. Studies have shown that a radial head excision can change elbow kinematics and decrease elbow stability. The radial head is also important in both valgus and varus laxity and displacement. However, the effect of radial head on ulnohumeral joint load is not known. The objective of this experimental study was to compare the axial loading produced at the ulnohumeral joint during active flexion with and without a radial head resection. Ten cadaveric arms were used. Each specimen was prepared and secured in an elbow motion simulator. To simulate active flexion, the tendons of the biceps, brachialis, brachioradialis, and triceps were attached to servo motors. The elbow was moved through a full range of flexion. To quantify loads at the ulnohumeral joint, a load cell was implanted in the proximal ulna. Testing was conducted in the intact then radial head resected case, in supination in the horizontal, vertical, varus and valgus positions. When comparing the average loads during flexion, the axial ulnar load in the horizontal position was 89±29N in an intact state compared to 122±46N during radial head resection. In the vertical position, the intact state produced a 67±16N load while the resected state was 78±23N. In the varus and valgus positions, intact state resulted in loads of 57±26N and 18±3N, respectively. Conversely, with a radial head resection, varus and valus positions measured 56±23N and 54±23N loads, respectively. For both joint configurations, statistical differences were observed for all flexion angles in all arm positions during active flexion (p=0.0001). When comparing arm positions and flexion angle, statistical differences were measured between valgus, horizontal and vertical (p<0.005) except for varus position (p=0.64). Active flexion caused a variation in loads throughout flexion when comparing intact versus radial head resection. The most significant variation in ulnar loading occurred during valgus and horizontal flexion. The vertical and varus position showed little variation because the position of the arm is not affected by the loss of the radial head. However, in valgus position, the resected radial head creates a void in the joint space and, with gravity, causes greater compensatory ulnar loading. In the horizontal position, the forearm is not directly affected by gravitational pull and cannot adjust to counterbalance the resected radial head, therefore loads are localised in the ulnohumeral joint. These findings prove the importance of the radial head and that a radial head resection can overload the ulnohumeral side

Total Elbow Arthroplasty (TEA) is a procedure to treat a number of conditions including rheumatoid arthritis (RA), post-traumatic arthritis, and osteoarthritis. To date, there has been minimal literature published on the Latitude since its release in 2001. There is one study reporting outcomes from the Latitude, a German study published in 2010. The purpose of this study was to analyse outcomes from primary Latitude TEAs. We performed a retrospective case series of 23 TEAs performed on 20 patients. 6 patients required revision surgery and were not included in the analysis. One patient was lost to follow up, resulting in 17 patients included for ROM analysis. All patients received Latitude TEA through a posterior approach and underwent a standard rehab protocol. 11 Patients were recalled at least two years post-op and were administered DASH and MAYO questionnaires. Complications such as triceps insufficiency, ulnar nerve dysfunction, infection, and aseptic loosening were recorded. Outcomes were compared using the Wilcoxon Signed-Rank test in STATA. Immediate post-op radiographs and patients most recent radiographs were analysed by a blinded upper-extremity surgeon not involved in the initial operation and analysed for loosening and implant malpostioning. Mean follow up was 4.8 years (range 2.6–7.5 years). Analysis of 17 TEAs in 16 patients revealed no difference in pre-operative ROM and post-operative ROM for flexion (121°±20 vs 129°±16, p=0.13) extension (40°±27 vs 27°±15, p=0.19), pronation (73°±13 vs 75°±24, p=0.55) or supination (64°±22 vs 68°±14, p=0.52). Patients who underwent TEA for RA had a significant improvement in flexion (121°±15 vs 135°±10, p<0.02). There was a statistically significant improvement in flexion-extension arc post-operatively (101°±28) compared to pre-operative scores (83±23 degrees, p<0.02). DASH and MAYO scores were calculated from 11elbows in 11 non-revision patients able to return for examination. The average MAYO score was 87.9 with nine patients in the “excellent” category, two patients in the “good” category, one patient in the “fair” category, and one in the “poor” category. The average DASH score was 32.9. Two patients underwent revision for periprosthetic fractures, two patients underwent revision for infection, one underwent revision for aseptic loosening and two for radial head dissociation (rate of 30%). This is one of the first studies examining the outcomes of the Latitude TEA. This retrospective case series demonstrates that the Latitude TEA has promising outcomes with respect to improving patient pain and functioning as assessed by the MAYO. Treatment using the Latitude TEA results in favorable functional outcomes for a majority of patients and offers an improvement in flexion-extension arc. Furthermore, our results are comparable to the MAYO scores reported by other studies analysing different prosthesis designs. The complication rate in our series was comparable to published rates of 20–40%

Aim. To compare radiological and clinical outcomes between triceps-detaching and triceps-sparing approaches in total elbow arthroplasty, with specific focus on cementing technique and post-operative range of motion. Methods. A retrospective review was completed of medical records and radiographs of 56 consecutively managed patients who underwent a primary total elbow arthroplasty between 2000 and 2012 at a tertiary hospital. Rheumatoid Arthritis was the predominant pathology (47/56). Data analysed included patient demographics, range of motion pre-operatively and at various stages post-operatively, approach utilized, operative time and complications. Cementing technique was graded as adequate, marginal or inadequate according to Morrey's criteria. Results. 12 patients were lost to follow-up or had incomplete records, leaving 44 patients for analysis. 15 patients had a triceps-sparing approach, and 29 had a variation of a triceps-detaching approach. Average follow-up was 56.1 months. Flexion range of motion in the triceps-sparing group improved from 25°–122° (±19.6°) pre-op to 10°–140° (±22.5°) at final follow-up, and in the triceps-detaching group from 41°–104° (± 22.2°) pre-op to 27°–129° (±35.0°) at final follow-up. Tourniquet time averaged 85.4 (±17.0) minutes for the triceps-sparing group and 96.1 (±22.6) minutes for the triceps-detaching group. The complication rate in the triceps-sparing group was 13.3%, and included one olecranon fracture and one case of superficial wound sepsis. The complication rate for the triceps-detaching group was 24.1%, and included one patient with persistent ulnar nerve symptoms requiring transposition, one medial condyle fracture and five triceps ruptures. Three patients who had attempted repairs of the rupture developed deep infections requiring multiple further surgeries. Cementing technique was adequate in 91.7% in the triceps-sparing group and in 70.6% in the triceps-detaching group and marginal in the remainder of the cohort. Conclusion. A triceps-sparing approach results in a predictable improvement in range of motion with no compromise of the cement mantle. NO DISCLOSURES

Aim. Chronic osteomyelitis still remains challenging and expensive to treat in spite of advances in antibiotics and operative techniques. We present our experience with free muscle flap after radical debridement of chronic osteomyelitis, performed as a single stage procedure. Methods. We retrospectively identified eight patients (5 Females) with mean age of 63 yrs (Range 40–71 yrs) Case notes were reviewed for co morbidities, Pre and post treatment inflammatory markers (plasma viscosity and CRP) and clinical staging. Mean follow up was 3 yrs (Range 1–6 yrs). All the patients were jointly operated by orthopaedic and plastic surgeons and underwent thorough debridement and muscle flap (Seven free flaps and one rotational flap) in the same sitting. All the patients were reviewed regularly by plastic and orthopaedic surgeons. Seven patients had free Gracilis flap and one had Triceps flap. Clinical assessment of reinfection was made on presence of erythema and wound discharge. Primary outcome measure was resolution of infection. Results. All patients had full resolution of osteomyelitis as evident by clinical examination and inflammatory markers. One patient had minor wound discharge at three years which settled with conservative management. One further patient developed eczematous dermatitis around the flap which was managed successfully by the dermatologist. Conclusions. We believe this to be the only study in which both the procedures (debridement and muscle flap) are performed in one sitting. This technique is a successful and useful addition to the armamentarium of surgeons in the management of chronic osteomyelitis

Trans-articular coronal shear fractures of the distal humerus pose a significant challenge to the surgeon in obtaining an anatomical reduction and rigid fixation and thereby return of good function. A variety of approaches have been described which include the extended lateral and anterolateral approaches and arthroscopically-assisted fixation for non-comminuted fractures. Fixation methods include open or percutaneous cannulated screws and headless compression screws directed either anterior to posterior or posterior to anterior. We describe an illustrated, novel approach to this fracture which is minimally invasive but enables an anatomical reduction to be achieved. A 15 year old male presented with a Bryan and Morrey type 4 fracture as described by McKee involving the left distal humerus. He was placed in a lateral position with the elbow over a support. A posterior longitudinal incision and a 6cm triceps split from the tip of the olecranon was made. The olecranon fossa was exposed and a fenestration made with a 2.5mm drill and nibblers as in the OK (Outerbridge-Kashiwagi) procedure. A bone lever was then passed though the fenestration and used to reduce the capitellar and trochlear fracture fragments into an anatomical position with use of an image intensifier to confirm reduction. The fracture was then fixed with two headless compression screws from posterior to anterior into the capitellar and trochlear fragments (see images). Early mobilisation and rehabilitation were commenced. Follow-up clinical examination and radiographs at six weeks revealed excellent range-of-motion and function with anatomical bony union. We believe that this novel approach to this fracture reduces the amount of soft tissue dissection associated with conventional approaches and their associated risks and also enables earlier return to function with restoration of anatomy

Between 1994 and 2002, 81 patients underwent ulnohumeral arthroplasty for elbow arthritis at our institution. All patients were sent a questionnaire with a request to attend for a clinical evaluation. Forty replied and 34 attended for clinical examination, 6 females and 34 males with an average age of 63 years (32-80) and a mean follow-up of 6 years (2-10). There were 22 (55%) patients with primary osteoarthritis, 14 (35%) with osteoarthritis secondary to trauma, two patients with rheumatoid arthritis and one patient each with arthrogryphosis multiplex congenital and post-septic arthritis of the elbow. Using the VAS (0-10), the pain score was seen to improve from a mean pre-operative score of 8 (6-10) to 4 (0-9). 21 patients (50%) were on minimal or no analgesia and 31 (75%) patients felt they would have the surgery again for the same problem. The arc of motion as regards flexion/extension was found to increase by 19% while prono-supination was found to increase by 30%. There was one patient each with superficial infection, anterior interosseous nerve neuropathy and myositic ossificans while two patients had triceps rupture. Radiological examination showed that in 12 cases the trephine hole was partially obliterated while in 4 cases it was completely obliterated. This could not be correlated clinically. Patients with loose bodies seemed to do better in the post-operative phase. Ulnohumeral arthroplasty has a role in the management of the arthritic elbow as it provides pain relief in the post-operative period; however, the improvement in the range of movement is limited particularly as regards the arc of extension
