Radial head fractures are the most common fractures occurring around the elbow and are often associated with other fractures or soft tissue injuries in the elbow. The purpose of this study was to characterise the morphology and to evaluate the outcome of the surgical management of radial head fractures in complex elbow injuries.

Nineteen patients with this pattern of injury underwent surgical treatment in our unit. In addition, seven patients had posterior dislocation of the elbow, 2 medial collateral ligament rupture, one capitellar fracture, 3 posterior Monteggia, 1 Essex-Lopresti lesion and 5 coronoid fracture plus posterior dislocation. Non comminuted radial head fractures were treated by open reduction and internal fixation or simple excision of small fragments. Patients with comminuted, displaced radial head fractures underwent radial head replacement.

The average follow up was 44 months. Two patients developed post-traumatic elbow contractures, one elbow instability and 2 mild arthritis. Overall, according to the DASH Outcome Measure, the results were excellent in 12 patients, fair in 3 and poor in 4.

In complex injuries of the elbow the characteristics of the radial head fracture and in particular the comminution, the fragment number, the displacement as well as the age of the patient should determine the appropriate surgical technique which will lead to satisfactory long-term results. Anatomical restoration and maintenance of elbow stability will allow early mobilisation of the elbow joint and should be the goals of surgical management.

Introduction: Chronic ruptures of the distal biceps tendon are relatively infrequent and are complicated by the retraction of the tendon and extensive scar formation, which preclude satisfactory repair. Bibliographical data presents different surgical procedures for the reconstruction of chronic ruptures using allograft soft-tissue constructs with varying results. The purpose of this study was to describe the surgical technique for reconstruction of the tendon with local soft tissue as graft and to report our experience with this procedure.

Methods: 17 patients with an average age of 54 years underwent surgical reconstruction of a chronic disruption of the distal biceps tendon. The mean interval between tendon rupture and reconstruction was 14 months. In all patients a flap from lacertus fibrosus was used in continuation with the remnants of the tendon. A based distally strip of the biceps was reversed and entubulated in the lacertous fibrosus flap and the whole construct was then advanced to the bicipital tuberosity. The biceps was released and mobilized as necessary. In addition, 3 patients underwent a fractional lengthening of the muscle. All procedures were performed through a single anterior approach. Anchors and anchor sutures were used to stabilize the tendon to the tuberosity.

Results: After an average duration of follow-up of 3.5 years, all patients had an excellent subjective result and they had all returned to their previous occupation. Furthermore, the strength of flexion and supination was comparable with that on the contralateral side in 13 patients. According to the Mayo Elbow performance score, the results were excellent in 9 patients, good in 4 and fair in 4. Complications that were encountered included a superficial infection which resolved with oral antibiotics, a transient median nerve palsy and a case of puncture wound of the brachial artery.

Conclusions: The aforementioned technique yields satisfactory postoperative results for this challenging problem with almost equal development of force and functionality on both sides and with a minimal possibility of re-rupture.

Aim: Postraumatic elbow stiffness is a common condition after elbow trauma. Sometimes it is a quite disabling symptom not responding to conservative measures. We present the surgical treatment of such cases of posttraumatic elbow stiffness.

Material: Twenty three patients, fourteen male and nine female with an average age of 34 yrs, underwent a surgical treatment of their stiff elbow. The average preoperative range of motion regarding elbow flexion-extension was 65° and the average rotational movement was 123°. All patients had received a resection of the anterior capsule, release or resection of posterior elements, removal of loose bodies and resection of osseous beaks if it was necessary. Two patients received a triceps lengthening. The results evaluated with the Mayo Elbow Performance Score.

Results: The average follow up was twenty nine months. All the patients were available for clinical assessment. There was an improvement of the average ROM to 115°, regarding flexion extension and to 164° regarding supination pronn. Postoperatively a dynamic elbow splint was used in twenty patients and a hinged external fixator in the remaining patients. Revision elbow release was performed in three patients and in one patient the elbow stiffness was deteriorated. Sixteen patients had an excellent or good result, and seven had a fair or poor one.

Conclusion: Elbow stiffness is an extremely disabling condition causing a functional impairment. Surgical elbow release is quite reliable, and relatively safe procedure given the fact that the patient follows strictly the rehabilitation protocol.

Aim: The aim of the study was to investigate the efficacy of the multidetector CT scan in the diagnosis and classification of pelvic and acetabular fractures.

Material and Method: 41 patients, 13 women and 28 men suspect for acetabular or pelvic fracture were examined. Patient’s ranged from 15 to 72 years. Fracture classification was based in that of Letournel and Judet. Examination was performed with a Multidetector CT scanner (Phillips-Brilliance), withnmultiple detectors and thin slices of 2 mm Multilevel and three dimensional reconstructions were performed.

Results: in 15 patients suspects for pelvic or acetabular fracture in plain xray, the CT scan was negative for revealing a fracture. In the rest 26 patients, there were 19 fractures of the anterior column, 4 fractures of the posterior column, 11 acetabular fractures and 7 sacral fractures. All the fractures were detected at the horizontal plane. MPR views were offered additional information for the sacral and acetabular fractures. In 7 patients the fractures diagnosed only after the CT scan was performed. In these patient plain x-rays were negative for fracture. In 6 patients the treatment algorithm was modified, based on CT scans findings

Conclusion: We believe that MDCT is an appropriate as well as an essential method in patients suspects for pelvic or acetabular injuries. MPR and three dimensional reconstructions are very helpful in revealing the personality of the fracture element very important for classification purposes as well as for planning treatment.

Aim: The aim of the study is to evaluate the usefulness of the MDCT scan in the diagnosis of calcaneal fractures and its use in the surgical treatment

Material. 112 calcaneal fractures were examined with a MDCT scan (slices one to two mm, pitch 1.5) with multilevel reconstruction as well as three dimensional reconstruction. The fractures were classified according to Munich classification system. Findings that were evaluated were the involvement of the subtalar joint, the number of fragments of the posterior facet and the extent of displacement.

Results: There were 85 intraartiular fractures and 27 extraarticular. 32 fractures were of type I according to Munich classification system (extraarticular without displacement). 15 fractures were of type II (extraarticular with some displacement). 2 fractures were of type III (intraarticular without displacement). 27 were of type IV (two fragments). 19 were of type V (with free fragments in the joint and 17 were type VI (more than four fragments).

Conclusion: The above mentioned radiological method of evaluating calcaneal fractures offers a quick diagnosis since it can depict the fragments and its displacement very accurately. Furthermore this method permits a very precise preoperative planning for the surgical treatment of these injuries

Backround: To present the results in a series of patients with complex distal radius fractures featuring comminution of the articular surface and the metaphysis in whom we used a volar as well as a dorsal approach in order to control the axial alignment and reconstitute the articular surface.

Material: There were sixteen patients with an average age of 26 years. All the fractures were classified as C3 according to AO Universal Classification. All the patients underwent an open reduction and internal fixation through a dorsal as well as a volar approach. Secondary operations were necessary for five patients.

Results: The average extension was 56, the average flexion was 51, pronation 70 and supination 76. The grip strength was 75% of the contralateral hand. The average ulnar inclination was 20°, 3 dorsal inclination, 0.9 mm ulnar variance and 1 mm articular incongruity. Three patients had radiological signs of radiocarpal arthritis. Excellent or good results achieved in the 40% of the patients according to the system of Green and O’Brien

Conclusion: The combination of dorsal and volar approach it is necessary for the carpus to be well aligned in order to achieve stability and give the opportunity for early mobilization. Sometimes additional operations are necessary.

Aim: The aim of this study is to evaluate the efficacy of the multidetector CT scan in shoulder fractures and to correlate these findings with those of plain x-rays.

Material and Method: A 105 patients with shoulder fracture were examined with a multidetector CT scanner after the acute injury. There were 64 male and 41 female with an average age of 52 yrs (range 16–95 yrs). The examination was performed with a CT PHILIPS BRILLIANCE, and six groups of detectors were used, with thin slices (1.6–2 mm). MPR and three dimensional reconstructions were performed.

Results: The mechanism of injury was fall during walk in 66 patients, fall from a height in 11 patients, and road traffic accident in 28 patients. They were detected 210 fractures at the shoulder region. A 135 fractures were located at the proxd imal end of the humerus, 75 at the scapula, in 95 out of 105 patients. In 10 patients with a comminuted fracture of the upper end of the humerus, the exact number of fragments as well as the precise location of them was not accurately assessed with plain xrays. MDCT control with multilevel anasynthesis and three dimensional reconstruction improved the understanding of the anatomic orientation in complex fractures and fractures–dislocations and in detection of subluxation of the fragments of the shoulder headin four part fractures in two patients.

Conclusion: Our results would orient us for using the MDCT scan in patients with acute shoulder injury, especially in cases with comminuted fractures, because it is better assessed the place, the orientation and the displacement of fragments, which are not easily identified in plain xrays. Furthermore, these reconstructions improve the preoperative planning in those patients

Aim: To retrospectively review the results of the use of adductor digiti quinti flap in failed cases of primary carpal tunnel tunnel release. The concept under this procedure is to provide a highly vascularised bed for axonal regeneration.

Material: Twenty cases of failed carpal tunnel release included in the study. The average age of patients was 43 years. There were thirteen female and five male patients. In two cases, one male and one female the procedure performed bilaterally.

All patients had a repeat of release ading a neurolysis of the median nerve. The adducor digiti quinti flap was dissected up to its neurovascular bundle and flipped over..

Results: In thirteen cases the procedure was successful as this was detected objectively and subjectively. In four cases the situation was unchanged and in three a revision surgery required for decompression of the nerve. Complex regional pain syndrome developed in three cases.

Conclusion: Although postoperative healing and rehabilitation time is lengthy due to more extensile dissection, pain relief, motor and sensory improvement, and hand dexterity justify the procedure.

We present a new inflatable self-locking intramedullary nailing system for the treatment of intertrocanteric and subtrochanteric fractures.

Material: We used this system in 63 cases with an average age of 81 yrs. 23 cases were intertrochanteric fractures and 40 cases subtrochanteric. A standard technique of closed reduction was used and the nail was implanted through an entry portal at the tip of the great trochanter.

Results. 38 patients were available for clinical and radiological examination. 13 patients were contacted by telephone and 12 patients could not be reached. The patients were mobilized with the instruction of weight bearing as tolerated. Each fracture was consolidated on average of 8 weeks. In two patients a cut out of the central peg was noted and the system was removed after fracture union. In three patients a mild malalignment was noted but without clinical significance. The mean blood loss was 90 cc and the mean operative time was 36 minutes.

Discussion The features of this system and the advantage of the technique include: fixation along the entire length of the nail, lack of distal interlocking screws, reduced exposure of the surgeon to x-ray and reduced operating time. Our results are very promising and it seems that this system is an innovative, effective, simple and minimally invasive treatment for fractures on the trochanteric region.

Introduction: Noncontiguous fractures of the tibial diaphysis and ipsilateral ankle is an uncommon entity. The aim of this study is to highlight the unique fracture pattern with emphasis on the necessity for surgical treatment. Material: There were 17 patients with an average age of 42 years, who sustained ipsilateral, noncontiguous fractures of the tibia and ankle. All but two fractures were closed. The level of the tibia fracture included midshaft (two), middle-distal third (ten), distal third (five). Eleven ankle fractures were classified as Weber B, five as Weber C and one Pilon. Two fractures were treated by cast immobilization, eleven with internal fixation of both fractures and four with a combination of internal and external fixation. Seven fractures were treated initially in long leg casts, but each required surgical intervention to control fracture alignment. Results: The average follow up was twenty-three months. The non-operatively treated fractures resulted in a malunion and decreased ankle mobility. Of the cases managed operatively, nine had complete structural and functional recovery; two patients regained 70% of ankle mobility and one developed post-traumatic ankle arthritis. Discussion: The resulted experience from the treatment of these injuries showed their extremely unstable nature. It has been our experience that the nature of the forces acting upon the fragments usually underestimated since reduction of one fracture displaces the other. Furthermore if acceptable reduction is achieved by closed means, progressive slippage of the fragments occurs. We believe that stable fixation of both fractures should be the treatment of choice

Introduction: Primary surgical treatment has been recommended for unstable clavicular fractures if consequences of non-union or malunion have to be avoided. A prospective study was undertaken to evaluate the results of a conservative treatment of very unstable fractures of the middle third of the clavicle, with emphasis to very early mobilization. Material: Patients to be included in the study had to met the following criteria: 1) Fractures of the middle third of the clavicle, severely displaced or comminuted, 2) Closed injuries, 3) No neurovascular complications, 4) No pneumothorax or hae-mothorax and 5) No other injury in the ipsilateral upper extremity. Twenty-three patients with an average age of 24 years included in the study. Each patient evaluated with AP and 45-degree cephalad-tilted views. All patients treated with an arm sling and strongly instructed for early mobilization. All patients were evaluated in a weekly interval and assessed with the American Shoulder and Elbow Surgeonñs shoulder evaluation form. Results: The average follow up was 21.4 months. All fractures were consolidated and all malunited; but no patient had residual symptoms or functional impairment of the limb. On patient developed mild hypesthesia in the ulnar nerve territory. Conclusion: The extremely encouraging results of our study, within the bounds of the above-mentioned follow up, indicate that conservative treatment with very early mobilization may be considered as a valid therapy. However it is a concern the functional result in a longer follow up as well as the cosmetic result.

Introduction: Common misconceptions about distal radius fractures result in undertreatment, particularly in active population.Loss of reduction can cause a symptomatic malunion. The aim of the study is to present the clinical consequences of a dorsally malunited distal radius fractures and the results of a corrective osteotomy for the treatment of this problem

Material: 18 patients with distal radius fractures healed in a dorsal angulation and a mean age of 39 years, treated with a corrective osteotomy. 13 patients had been treated by closed means, and 5 had undergone a earlier surgical procedures without success. 11 patients had a DISI instability of the wrist. 12 patients underwent a radius corrective osteotomy alone, 4 had a cpmined radial osteotomy amd ulnar shortening osteotomy, and 2 underwent only a Sauve-Kapandji procedure.

Results: The average follow up was 26 months. All the osteotomies healed. 15 of the deformities were corrected. 7 patients with DISI deformity were regained normal wrists whereas the rest 4 remained with DISI instability. One patient with normal wrist led to DISI instability postop.

Conclusion: Distal radius corrective osteotomy is a technically demanding operation, and by no means can guarantee a postop normal anatomy. Furthermore and despite the functional improvement it is unknown the remote consequences wth a ersidual DISI deformity.

Introduction: We describe an operation, which have performed in patients with rheumatoid arthritis, valgus deformities of the ankle and hind foot with overlying ulcer.

Materials and Methods: The operation has been performed in seven female patients with an average age of 69 years. All patients had severe functional problems.

Technique: The ulcer is excised through an elliptical incision and the medial malleolous is excised level with the ankle joint. Then the tibia surface is osteotomized just above the ankle joint with a planar cut perpendicular to the long axis of the tibia in both saggital and coronal planes. The talus is also transected, with the cut parallel to the sole of the foot and the arthrodesis is closed. The patient starts to mobilize weight bearing in a POP cast with an over boot with rigid sole and rocher in 2–3 days. After 8 weeks the patient is transferred to a shoe with fixed double iron attached. This is retained until radiological union occurs.

Results: Primary healing of the skin was obtained in all cases. Each patient was able to walk within the bounds of their disease early after surgery. In every case union has been delayed. No patient has had recurrent deformity or ulceration.

Conclusion: Such deformity severely impairs the functional status of the patient and may threaten the viability of the foot. Primary surgery with excision of the medial malleolous and correction of the deformity of the ankle has proved successful in treating pain, deformity and ulceration in this small series.

Introduction: Various surgical techniques existed for the treatment of three and four part proximal humeral fractures with variable outcomes. The aim of this study is to present a technique using small materials, to preserve all the biologic principles of fracture fixation, in the treatment of these challenging injuries.

Material: We perform a study taking as inclusion criteria: 3 and 4 parts proximal, closed, humeral fractures, treated surgically by open reduction and a modular biological internal fixation.

Surgical technique: Through a standard deltopectoral approach the fragments reduced, taking care to preserve the periosteum and manipulate meticulously the soft tissues. All the fractures were fixed with a combined system of Kirschner wires inserted to the proximal fragments, connected by “bone clips” forming a modular construction and fixed to the main distal fragment by AO screws.

Results: 24 patients complied with the inclusion criteria and were followed up a mean of 18 months. All patients achieved a satisfactory result except a fracture-dislocation that developed AVN and was revised into a shoulder arthroplasty and two demented elderly patients with metalware failure that were also revised.

Conclusion: In this first series of non-selected cases the outcome of fracture consolidation is promising. Although this technique is in its embryonary phase of development and the functional results are currently been assessed, the radiological outcomes suggest that the technique described is a valid alternative to the treatment of these fractures if we indicate an osteosynthesis method that combines biology and stability.

Introduction: The aim of the study was to assess the efficacy of the distal radius π-plate in the surgical treatment of acute, dorsally displaced, unstable distal radius fractures.

Material: 37 patients with an average age of 41 yrs included in the study. Upon dorsal exposure of the fracture and provisional reduction with the aid of a distractor and K-wires, a bending template was used to verify plate length and contour. The plate was then applied and the type, number and location of screws and buttress pins to be used were determined. Eight patients had supplementary fixation. Autologus bone graft was used to fill defects in 28 patients.

Results: The average follow up was 21 months. Radiographic evidence of union was documented at an average of 6 weeks postop. No loss of reduction occurred in any of the patients and no patient complained of residual deformity. The average ROM was 79% of the contralateral side, the average grip strength was 64% of the contralateral wrist and the average pinch strength was 76% of the contralateral hand. No infections, nonunions, wound problems or plate failures occurred. 5 patients developed irritation and 4 had their plates removed.

Concussion: The results of this study verify the safety and the efficacy of the π-plate for the treatment of complex fractures of the distal radius. Furthermore considering the technical advantages of the π,-plate it seems that complex distal radius fractures can effectively be addressed through a dorsal approach and stable internal fixation.

Introduction: Noncontiguous fractures of the tibial diaphysis and ipsilateral ankle is an uncommon entity. The aim of this study is to highlight the unique fracture pattern with emphasis on the necessity for surgical treatment.

Material: There were 11 patients with an average age of 40 years, who sustained ipsilateral, noncontiguous fractures of the tibia and ankle. All but one fracture ware closed. The level of the tibia fracture included midshaft (two), middle-distal third (seven), distal third (two). Seven of the ankle fractures were classified as Weber B, three as Weber C and one Pilon. One fracture was treated by cast immobilization, eight with ORIF of both fractures and two with a combination of internal and external fixation. Of the patients treated operatively, five were treated initially in long leg casts, but each required surgical intervention to control fracture alignment.

Results: The average follow up was twenty- three months. The non-operatively treated fracture resulted in a mal-union and a severe loss of ankle mobility. Of the cases managed operatively, seven had complete structural and functional recovery, two patients regained 70% of ankle mobility and one developed ankle arthritis.

Discussion: The resulted experience from the treatment of these injuries shows their extremely unstable nature. It has been our experience that the forces acting upon the fragments usually underestimated since reduction of one fracture displaces the other. Furthermore if acceptable reduction is achieved by closed means, a progressive slippage occurs over the time. We believe that stable fixation of both fractures should be the treatment of choice.

Objective: Deformity post distal radius fracture can be associated with alterations in carpal kinematics. This study presents a review to detect the prevalence and clinical implications of such deformities and the variables that influence the outcome following osteotomy.

Material & Methods: 29 patients with distal radius mal-union, and an average age of 43 yrs, were treated by a single surgeon with a corrective osteotomy. Along with pain scales, wrist motion, and grip strength, pre and post osteotomy radiographs were evaluated. Preoperatively, 18 patients had dorsal deformity, 9 volar and 2 shortening and malrotation alone. 20 patients had carpal malalignment and 9 normal carpal alignment.

Results: The average follow up was 21 months. 24 out of 29 radial deformities were corrected to normal. Overall 17 patients had post-op normal carpal alignment. Three groups resulted; Group I: 11 patients with pre and post-op “fixed” deformities. Group II: 8 patients with normal pre and post-op carpal alignment; and Group III: 9 patients with “lax” pre-op malalignment converted to normal post-op. 1 patient was normal pre-op and converted to DISI at post-op. There was no statistically difference in outcome with regard to pain, forearm rotation, wrist extension, patient age or time to surgery between the three groups. There was statistically significant greater wrist flexion in Group II and III compared to Group I.

Conclusions: Carpal malalignement post radius osteotomy will have a negative effect on the functional outcome compared to those patients with preoperative carpal deformity, which corrects with radius osteotomy. Knowledge of this association will help advice patients of expected outcomes.

Introduction: The aim of this study was to compare the serum cobalt and chromium levels in patients with Oxford Universal hips and Cenator hips. Both systems are composed of cobalt chromium alloy and have modular cobalt chromium heads, however only the Oxford hip has a sliding mechanism.

Material: The serum levels of chromium and cobalt were measured in 20 patients with Oxford Universal Hip replacement (Group 1). This was compared to the serum levels of chromium and cobalt in 17 patients with Cenator Hip replacement (Group 2) and 20 patients with no implants (Group 3). Patients in Group 1 and 2 were assessed clinically and with plain radiographs. Patients were excluded if there was evidence of loosening, if they had other joint implants or any other known cobalt or chromium implant and if they had impaired renal function. All hip replacements were performed as primary procedures. Specimens were analysed by electrothermal atomization atomic absorption spectrometry.

Results: There was no statistically significant difference in serum cobalt and chromium levels between groups 1 and 2. Patients in groups 1 and 2 had statistically significant higher serum levels of chromium and cobalt than group 3 patients.

Discussion: This study demonstrates that serum levels of chromium and cobalt are elevated in patients with stable hip implants composed of this alloy but not in a normal population. Although it is not known what the long-term effects of chronic low-grade exposure to these ions are, these levels are many order of magnitude below the toxic range. Furthermore, our results show that the Oxford Universal Hip releases no more metal ions into the circulation than an implant without a sliding mechanism.

Purpose: The purpose of the study is to compare the disease severity at the time of surgical intervention between patients undergoing primary joint replacement under the National Health Service and Private Health-care Systems.

Materials: 166 patients were included in the study – 101 NHS and 65 Private. Inclusion criteria were: 1) hip or knee osteoarthritis, 2) primary joint replacement, and 3) informed consent of the patient. Patients with arthropathy of inflammatory, infectious or neoplastic aetiology were excluded. Physician evaluation included medical history, calculation of Charleson Comorbidity Scores, and Knee Society rating. Patients were given self-assessment health questionnaires including WOMAC, SF-36, and Nottingham Health Profile.

Results: Mean age was 69.4 years and did not vary significantly between NHS and Private groups. Charleson Comorbidity Scores were significantly worse in the NHS group than in the private. Health assessment questionnaire scores were all adjusted for age, sex, and comorbidity. In NHS patients undergoing TKR, we demonstrate significantly worse pre-operative comorbidity than in private group for indices of function and pain. Patients undergoing THR showed little difference in pre-operative comorbidity.

Conclusion: NHS patients undergoing primary TKR have significantly more advanced disease than their counterparts who are privately insured. Access to TKR surgery is determined by the healthcare delivery system rather then a threshold level of disease severity. Further follow-up of the outcomes of TKR in these two groups needs to be carried out to determine the long-term effects of accessing surgical care at a more advanced stage of disease.

Introduction: The aim of this study is to present a modification of the single tension band technique for the treatment of olecranon fractures, using a double tension band with smaller wires, preserving all the biological parameters for fracture fixation, in an effort to decrease related complications.

Material: Thirty-three patients with olecranon fractures treated with a double tension band fixation. Surgical Technique: Through a posterior approach the fracture is reduced keeping all principles for biologic fixation and stabilized with two parallel small K-wires inserted from the olecranon process and exit through the anterior cortex of the ulna. Then the extensor carpi ulnaris and flexor carpi ulnaris are partly elevated from the ulna and two 1.5-mm transverse drill holes are made through the ulna 3 and 4 cm distal to the fracture. Two 22-gauge wires are passed through the proximal and distal holes, bent into a figure of 8 over the dorsal ulna and simultaneously tightened. The proximal ends of the K-wires are bent and impacted into the olecranon process.

Eleven patients needed supplemental fixation with screws. All patients mobilized the first postop day.

Results: All the fractures consolidated. All patients but two regained full range of motion. No hardware failure was noted except one patient in whom one band was broken but without clinical relevance.

Conclusion: It seems that a double tension band fixation despite the smaller material utilized, provides a very stable construct, permitting early mobilization. Furthermore two bands tensioned independently provide greater compression forces at the fracture site and offer a back up in case that one band fails.
