Subtrochanteric femoral fractures are a subset of hip fractures generally treated with cephalomedullary nail fixation\[1\]. Single lag screw devices are most commonly-used, but integrated dual screw constructs have become increasingly popular\[2,3\]. The aim of this study was to compare outcomes of fixation of subtrochanteric femoral fractures using a single lag screw (Gamma3 nail, GN) with a dual screw device (InterTAN nail, IN). The primary outcome was mechanical failure, defined as lag screw cut-out, back-out, nail breakage or peri-implant fracture.

Consecutive adult patients (18yrs) with subtrochanteric femoral fracture treated in a single centre were retrospectively identified using electronic records. Patients that underwent surgical fixation using either a long GN (2010–2017) or IN (2017–2022) were included. Medical records and radiographs were reviewed to identify complications of fixation. Cox regression analysis was used to determine the risk of mechanical failure and secondary outcomes by implant design. Multivariable regression models were used to identify predictors of mechanical failure.

The study included 622 patients, 354 in the GN group (median age 82yrs, 72% female) and 268 in the IN group (median age 82yrs, 69% female). The risk of any mechanical failure was increased two-fold in the GN group (HR 2.44 \[95%CI 1.13 to 5.26\]; _p=0.024_). Mechanical failure comprising screw cut-out (_p=0.032_), back-out (_p=0.032_) and nail breakage (_p=0.26_) was only observed in the GN group. Technical predictors of failure included varus >5° for cut-out (OR 19.98 \[2.06 to 193.88\]; _p=0.01_), TAD;25mm for back-out (8.96 \[1.36 to 58.86\]; p=0.022) and shortening 1cm for peri-implant fracture (7.81 \[2.92 to 20.91\]; _p=<0.001_).

Our results demonstrate that an intercalated screw construct is associated with a lower risk of mechanical failure compared with the a single lag screw device. Intercalated screw designs may reduce the risk of mechanical complications for patients with subtrochanteric femoral fractures.

A fracture of the tuberosity is associated with 16% of anterior glenohumeral dislocations. Manipulation of these injuries in the emergency department is safe with less than 1% risk of fracture propagation. However, there is a risk of associated neurological injury, recurrent instability and displacement of the greater tuberosity fragment. The risks and outcomes of these complications have not previously been reported. The purpose of this study was to establish the incidence and outcome of complications associated with this pattern of injury.

We reviewed 339 consecutive glenohumeral dislocations with associated greater tuberosity fractures from a prospective trauma database. Documentation and radiographs were studied and the incidence of neurovascular compromise, greater tuberosity fragment migration and intervention and recurrent instability recorded.

The mean age was 61 years (range, 18–96) with a female preponderance (140:199 male:female). At presentation 24% (n=78) patients had a nerve injury, with axillary nerve being most common (n=43, 55%). Of those patients with nerve injuries 15 (19%) did not resolve. Greater tuberosity displacement >5mm was observed in 36% (n=123) of patients with 40 undergoing acute surgery, the remainder did not due to comorbidities or patient choice. Persistent displacement after reduction accounted for 60 cases, later displacement within 6 weeks occurred in 63 patients. Recurrent instability occurred in 4 (1%) patients. Patient reported outcomes were poor with average EQ5D being 0.73, QDASH score of 16 and Oxford Shoulder Score of 41.

Anterior glenohumeral dislocation with associated greater tuberosity fracture is common with poor long term patient reported outcomes. Our results demonstrate there is a high rate of neurological deficits at presentation with the majority resolving spontaneously. Recurrent instability is rare. Late tuberosity fragment displacement occurs in 18% of patients and regular follow-up for 6 weeks is recommended to detect this.

Though knee osteoarthritis (OA) is diagnosed and monitored radiographically, full thickness cartilage loss (FTCL) has rarely been correlated with radiographic classification. This study aims to analyse which classification system correlates best with FTCL and assessing their reliability.

Prospective study of 300 consecutive patients undergoing total knee arthroplasty (TKA) for OA. Two blinded examiners independently graded preoperative radiographs using 5 systems: Kellgren-Lawrence (KL); International Knee Documentation Committee (IKDC); Fairbank; Brandt; and Ahlback. Interobserver agreement was assessed using the intraclass correlation coefficient. Intraoperatively, anterior cruciate ligament (ACL) status and FTCL in 16 regions of interest were recorded. Radiographic classification and FTCL were correlated using the Spearman correlation coefficient.

On average, each knee had 6.8±3.1 regions of FTCL, most common medially. The commonest patterns of FTCL were medial with patellofemoral (48%) and tricompartmental (30%). ACL status was associated with pattern of FTCL (p=0.02). All classification systems demonstrated moderate ICC, but this was highest for IKDC: whole knee 0.68 (95%CI 0.60–0.74); medial compartment 0.84 (0.80–0.87); and lateral compartment 0.79 (0.73–0.83). Correlation with FTCL was strongest for Ahlback (Spearman rho 0.27–0.39) and KL (0.30–0.33), though all systems demonstrated medium correlation. The Ahlback was the most discriminating in severe OA. Osteophyte presence in the medial compartment had high positive predictive value for FTCL, but not in the lateral compartment.

The Ahlback and KL systems had the highest correlation with confirmed cartilage loss. However, the IKDC system displayed best interobserver reliability, with favourable correlation with FTCL in medial and lateral compartments, though less discriminating in severe disease.

Glenohumeral dislocation is complicated with a greater tuberosity fracture in 16% of cases. Debate regarding the safety of closed reduction in the emergency department exists, with concerns over fracture propagation during the reduction manoeuvre. The study aim was to report the results of closed reduction, identify complications and define outcome for these injuries.

188 consecutive glenohumeral dislocations with a tuberosity fracture were identified from a prospective database from 2014–2017. 182 had an attempted closed reduction under appropriate sedation using standard techniques, five were manipulated in theatre due to contra-indications to sedation. Clinical, radiographic and patient reported outcomes, in the form of the QuickDASH and Oxford Shoulder Score (OSS), were collected.

A closed reduction in the emergency department was successful in 162 (86%) patients. Two iatrogenic fractures of the proximal humerus occurred, one in the emergency department and one in theatre, representing a 1% risk. 35 (19%) of patients presented with a nerve lesion due to dislocation. Surgery was performed in 19 (10%) cases for persistent or early displacement (< 2 weeks) of the greater tuberosity fragment. Surgery resulted in QuickDASH and OSS scores comparable to those patients in whom the tuberosity healed spontaneously in an anatomical position (p=0.13). 18 patients developed adhesive capsulitis (10%).

Glenohumeral dislocation with greater tuberosity fracture can be safely treated by closed reduction within the emergency department with a low risk of humeral neck fracture. Persistent or early displacement of the tuberosity fragment will occur in 10% of cases and is an indication for surgery.

There is currently no information regarding long-term outcomes following total hip replacement (THR) for hip fracture in patients selected in accordance with national guidelines. We define the long-term outcomes and compare these to short-term outcomes in the same previously reported cohort.

We prospectively identified patients who underwent THR for a displaced hip fracture over a 3-year period from 2007–2010. These patients were followed up at 10 years using the Oxford hip score(OHS), the Short-form 12(SF-12) questionnaire and satisfaction questionnaire. These outcomes were compared to the short-term outcomes previously assessed at 2 years. We identified 128 patients. Mean follow up was 10.4 years. 60 patients(48%) died by the time of review and 5 patients(4%) developed dementia and were unable to respond. 3 patients were untraceable. This left a study group of 60 patients with a mean age of 81.2.

Patients reported excellent outcomes at 10 year follow up and, when compared with short-term outcomes, there was no statistically significant change in levels of satisfaction, OHS, or SF-12. The rates of dislocation(2%), deep infection(2%) and revision(3%) were comparable to those in the literature for elective THR. Mortality in the hip fracture group at 10 years is lower than that of elective registry data.

Long-term outcomes for THR after hip fracture in selected patients are excellent and the early proven benefits are sustained. Our data validates the selection process of national guidelines and confirms low complication rates. THR is a safe and highly effective treatment for fit elderly patients with displaced hip fractures.

Limited long term data exists comparing operatively and non-operatively treated Achilles tendon ruptures. A previous randomised controlled trial comparing early outcomes showed a short term advantage for surgery, but there are no long term prospective randomised comparisons. Our aim was to determine whether surgery conferred long term benefits in terms of patient reported outcomes or re-rupture.

64 patients (80%) were followed up with postal questionnaires. Patients were asked to complete the Short Musculoskeletal Function Assessment (SMFA), Achilles Tendon Total Rupture Score (ATRS) and EQ-5D questionnaires, and to report re-ruptures.

32 patients were treated non-operatively and 32 operatively; 59 completed the SMFA and 64 the ATRS and EQ-5D assessments. There was no significant difference in SMFA score (median 1.09, IQR 4.89 in the cast group versus 2.17 and 7.07 in the operative group; p=0.347), ATRS (median 96, IQR 18 versus 93 and 15; p=0.509), EQ-5D Index (median 1.0, IQR 0.163 versus 1.0 and 0.257; p=0.327) and EQ-5D Visual Analogue Score (median score 85, IQR 15 versus 85 and 24; p=0.650). There were 2 re-ruptures in the operative group and 4 in the non-operative group (p=0.067).

This is the first prospective, randomised, long term report comparing operative and non-operative management. At follow up between 13–17 years after injury, patients reported good function and health related quality of life. There was no significant difference in re-rupture rate between the treatment groups.

Aim

The aim of this study was to determine whether the absence of periosteal reaction on plain radiographs was predictive of exchange nail failure in lower limb diaphyseal fracture non-unions.

Methods

A consecutive cohort of 20 femora and 35 tibiae undergoing exchange nailing for diaphyseal aseptic (n=39) and septic (n=16) fracture non-union at a single centre from 2003 to 2010. Multiple causes of non-union were found in 29 patients (53%) with infection present in 16 cases (29.1%). Of this cohort 49 fracture non-unions had complete radiographic records (19 femora and 30 tibiae) allowing evaluation of the periosteal callus. The primary outcome was the number of number of revision procedures required to achieve union. Failure was defined was as the requirement of >two revision procedures to achieve union.

Background

Acetabular fractures occur as a result of high-velocity trauma and are often associated with other life threatening injuries. Approximately one-third of these fractures are associated with dislocation of the femoral head but there are only few studies documenting the long term outcomes of this group of acetabular fracture.

Methods

This was undertaken at the Royal Infirmary of Edinburgh which provides the definitive orthopaedic treatment for all major trauma including all acetabular fractures for the South East of Scotland. We retrospectively reviewed patients who sustained an acetabular fracture associated with a posterior hip dislocation from a prospectively gathered trauma database between 1990 to 2010. Patient characteristics, complications and the requirement for further surgery were recorded. Patient outcomes were measured using the Oxford Hip score and Short Form SF-12 health survey.

The aim of this study was to identify risk factors for failure of exchange nailing for femoral diaphyseal fracture non-unions. The study cohort comprised 40 patients with femoral diaphyseal non-unions treated by exchange nailing. The main outcome measures were union, number of secondary fixation procedures required to achieve union and time to union. Univariate analysis and multiple regression were used to identify risk factors for failure to achieve union.

The mean age of the patients at exchange nail surgery was 37 years. The median time to exchange nailing from primary fixation was 8.4 months. Multiple causes for non-union were found in 14 (35.0%) cases, with infection present in 12 (30.0%) patients. Further exchange procedures were required in nine (22.5%) cases, one patient (2.5%) required the use of another fixation modality, to achieve union. Union was ultimately achieved in 35 (94.5%) patients. The median time to union was 9.4 months after the exchange nail procedure. Univariate analysis confirmed that cigarette smoking and infection were predictive of failure (p<0.05). Multi-regression analysis found that Gustilo-Anderson grade, presence of dead bone or a gap and infection were predictive of exchange nail failure (p <0.05).

Exchange nailing is an effective treatment for aseptic femoral diaphyseal fracture non-union. Patients with infection required more than one procedure. Smoking, infection and the presence of dead-bone or a gap at the fracture site were associated with an increased risk of further fixation surgery.

This study reports on the natural history of acetabular fracture dislocations. We retrospectively reviewed patients who sustained an acetabular fracture associated with a posterior hip dislocation from a prospective database. Patient characteristics, complications and the requirement for further surgery were recorded. Patient outcomes were measured using the Oxford Hip score and Short Form SF-12 health survey.

A total of 99 patients were treated over a 24 year period. The mean age was 41 years. Open reduction and internal fixation was performed in the majority (n=87), 10 were managed conservatively following closed reduction and two underwent primary total hip replacement (THR). At a median follow up of 12.4 years (range 4–24 years) patient outcomes were available for 53 patients. 12 patients had died. 19 patients went onto have a THR as a secondary procedure, of which 11 had confirmed avascular necrosis. Median time to THR was 2 years (range 1–17 years). The mean Oxford hip score was 35 (range 2–48), SF-12 physical component score (PCS) was 40 and a third of the patients used a walking aid. In THR group the mean Oxford score was 32 (range 3–46), SF-12 PCS was 39 and almost all required a walking aid.

This is the first study to present the long term outcomes following an acetabular fracture dislocation. Our study suggests there is considerable disability in this group of patients and the requirement for subsequent THR has inferior patient reported outcomes.

We define the medium-term outcomes following total hip replacement (THR) for hip fracture. There is currently no information regarding longer term clinical and patient reported outcomes in this group of patients selected in accordance with national guidelines.

We prospectively identified patients who underwent THR for a displaced hip fracture over a three year period between 2007 and 2010. These patients were followed up at 5 years using the Oxford hip score, Short-form 12(SF-12) questionnaire and satisfaction questionnaire.

We identified 128 patients. Mean follow up was at 5.4 years with a mean age of 76.5 years. 21 patients (16%) had died, 12 patients (9%) had developed dementia and 3 patients had no contact details, leaving a study group of 92 patients. 74 patients(80%) responded. Patients reported excellent functional outcomes and satisfaction at 5 years (mean Oxford Hip Score 40.3; SF-12 Physical Health Composite Score 44.0; SF-12 Mental Health Composite Score 46.2; mean satisfaction 90%). The rates of dislocation (2%), deep infection (2%) and revision (3%) were comparable to those quoted for elective THR. When compared with 2 year follow up, there was no statistically significant change in outcome.

Medium-term outcomes for THR after hip fracture are excellent and the early proven benefits of this surgery are sustained. Mortality rates are equivalent to elective THR registry data and significantly lower than overall mortality rates following hip fracture. Our data validates the selection process detailed in national guidelines and confirms the low complication rate. THR is a safe and highly effective treatment for fit elderly patients with displaced hip fractures.

The aim of this study was to identify risk factors for failure of exchange nailing in tibial diaphyseal fracture non-unions. The cohort comprised 99 tibial diaphyseal fracture non-unions treated by exchange nailing. The mean age of the patients at exchange nail surgery was 36 years. The median time from primary fixation to exchange nailing was 6.4 months. The main outcome measures were union, number of secondary fixation procedures required to achieve union and time to union. Univariate analysis and multiple regression were used to identify risk factors for failure to achieve union.

Multiple causes for non-union were found in 31.3% cases, with infection present in 32.3%. Further exchange procedures were required in 35.4%, 7.1% required the use of other fixation modalities. Union was ultimately achieved in 97.8%. The median time to union was 8.7 months. Univariate analysis revealed that cigarette smoking, an atrophic pattern of non-union and infection were predictive for failure of exchange nailing (p<0.05). Multi-regression analysis found that only infection was statistically significantly predictive (p<0.05) of exchange nail failure.

Exchange nailing is an effective treatment for tibial diaphyseal non-unions even in the presence of infection. Smoking, atrophic pattern of non-union and infection are associated with an increased risk of further fixation surgery.

Tibial plateau fractures are common intraarticular fractures. The principal long-term complication is post-traumatic osteoarthritis (PTOA) with the usual salvage procedure being total knee arthroplasty (TKA). Our aim was to define the incidence of PTOA requiring TKA following tibial plateau fractures and identify the risk factors.

We looked at all tibial plateau fractures between 1995 and 2008. There were 888 tibial plateau fractures. 23% were Schatzker I, 25% II, 14% III, 22% IV, 8% V and 8% VI. To date 25 have undergone TKA (2.8%). The mean age of patients at time of fracture was 56 in the overall cohort and 65 in those requiring TKA; this was statistically significant (p=0.04). 4% of females with tibial plateau fractures required TKA in comparison to 2% of males. The Schatzker I fractures were the least likely to require TKA at 1% with the most likely requiring arthroplasty surgery being type III at 6%. Only 1% of the patients treated non-operatively later underwent TKA

The overall incidence of TKA after tibial plateau fractures was 3%. For displaced fractures requiring internal fixation this rose to 4%. Risk factors were increasing age, split depression fractures and female gender. Although tibial plateau fractures are commonly associated with degenerative radiographic changes, we concluded that the incidence of symptomatic OA severe enough to require TKA is low.

Background

There is increasing interest in the use of Total Hip Replacement (THR) for reconstruction in patients who have suffered displaced intracapsular hip fractures. Patient selection is important for good outcomes but criteria have only recently been clearly defined in the form of national guidelines. This study aims to investigate patient reported outcomes and satisfaction after Total Hip Replacement (THR) undertaken for displaced hip fractures and to compare these with a matched cohort of patients undergoing contemporaneous THR for osteoarthritis in order to assess the safety and effectiveness of national clinical guidelines.

Methods

100 patients were selected for treatment of displaced hip fractures using THR between 1 January 2007 and 31 December 2009. These patients were selected using national guidelines and were matched for age and gender with 300 patients who underwent contemporaneous THR as an elective procedure for osteoarthritis.

The outcome of 77 high energy tibial plateau fractures treated by locking or conventional plating was reviewed. The aim of the study was to determine if there was any advantage of locking plates in reducing the complication rates associated with fixation of these injuries. All patients had a high energy injury pattern (medial or bicondylar plateau fractures). There were 32 locked plates and 45 non-locking plates used.

Compartment syndrome complicated 5 patients (16%) in the locked plate group and 3 (7%) in the non-locked group (p = 0.198). Superficial infection occurred in 4 (13%) patients with locked plates and 7 (16%) patients with non-locked plates. Thromboembolic complications occurred in 3 (7%) patients treated with non-locked plates. There were no thrombembolic complications in the locked plate group (p = 0.135).

Overall, malunion of the plateau occurred in 10 (22%) patients treated with non-locked plates compared to 7 (22%) patients who received locked plates. This was due to residual malreduction in 4 (13%) patients in the locked plate group and 6 (13%) patients in the non-locked plate group at the time of surgery. In the remaining cases loss of reduction after fixation occurred in 4 (9%) patients who received non-locked plates and in 3 (9%) patients who were treated with locked plates. No statistically significant difference was noted in the treatment outcomes of patients managed with locked plates or non-locked plates, regardless of fracture severity.

We concluded that there is no definite advantage associated with the use of locked plating for high energy tibial plateau fractures.

Background

Hyperlaxity is associated with a high incidence of shoulder dislocations. Collagen V regulates the diameter of fibrils of the abundant collagen type I. Decorin and biglycan are members of the small leucine rich proteoglycans(SLRP's)family and play important roles in the regulation of collagen fibrillogenesis. The aim of this study was to identify if there was a link in hyperlaxity, capsule strength, collagen V and SLRP's expression.

Methods

Data was collected for 10 patients undergoing open shoulder stabilization for recurrent instability. Beighton score was used to assess hyperlaxity. Localization of Collagen V and SLRP's was studied by immunohistochemical staining of paraffin embedded sections of shoulder capsule. Grading of the stain was done on a 0-4 scale(0=no staining and 4=strong staining>50% of the slide)by three observers. Shoulder capsules were mounted on a material testing system and vertical load was applied to reach yield.

Background

Hyperlaxity is associated with a high incidence of sporting injuries. Collagen V regulates the diameter of fibrils of the abundant collagen type I. Decorin and biglycan are members of the small leucine rich proteoglycans(SLRP's)family and play important roles in the regulation of collagen fibrillogenesis. The aim of this study was to identify if there was a link in hyperlaxity, tissue strength, collagen V and SLRP's expression.

Patients and methods

Data was collected for 25 patients. 12 had open shoulder stabilization and 13 had primary ACL reconstruction. Beighton score was used to assess hyperlaxity. Localization of Collagen V and SLRP's was studied by immunohistochemical staining of the paraffin embedded sections of the skin. Grading of the stain was done on a 0-4 scale(0=no staining and 4=strong staining>50% of the slide)by three observers. Tissue specimens were mounted on a material testing system and vertical load was applied to reach yield.

Purpose

The aim of the present study was to investigate the relationship between generalised ligament laxity and requirement for revision ACL reconstruction.

Materials and methods

126 patients undergoing primary ACL reconstruction were included in the study along with 35 patients undergoing revision ACL surgery. 62 patients without any knee ligament injury formed an age and sex matched the control group.

The Beighton score was used to quantify the ligamentous laxity in all cases with a score more than 4 classified as having generalised ligamentous laxity. The revision ACL patients were evaluated to identify technical errors at the time of the primary procedure or subsequent traumatic injury that could have contributed to primary graft failure.

The aims of this study were to undertake a prospective randomised trial to compare functional outcome, and range of motion after treatment of medial collateral ligament injuries by either early unprotected mobilisation or mobilisation with a hinged brace.

Patients were randomised into either unprotected mobilisation or mobilisation with a hinged brace. Assessments occurred at 2 weeks, 6 weeks, 3 months and 6 months. Outcome measures included validated questionnaires (International Knee Documentation Committee and Knee Injury and Osteoarthritis Outcome Score scores), range of motion measurements and strength testing.

Eighty six patients (mean age 30.4) were recruited. There were 53 men and 33 women. The mode of injury was sport in 56 patients (65%) with football, rugby and skiing being the most common types of sport involved.

The mean time to return to full weight bearing was 3 weeks in both groups. The mean time to return to work was 4.6 weeks in the braced group and 4.1 weeks in the non-braced group (p=0.79).

Return to running was at a mean of 14.3 weeks in the braced group and 12.8 weeks in the non-braced group (p=0.64). Return to full sport was 22 weeks in the braced group and 22.1 weeks in the non-braced group (p=0.99). There was no significant difference in range of movement or pain scores between the two groups at 2,6,12 and 24 weeks.

The use of a hinged knee brace does not influence recovery after a medial collateral injury.
