HYDROTHERMAL ABLATION IN RECURRENT OR CHRONIC OLECRANON BURSITIS: A PROSPECTIVE STUDY.

BACKGROUND: Olecranon bursitis can be difficult to treat, resulting in persistent or recurrent symptoms. Bursectomy is a frequently applied treatment option for refractory cases but has high complication rates. This is the first in-vivo study to investigate the safety and efficacy of hydrothermal ablation, a new treatment modality for recurrent or chronic olecranon bursitis that aims to cause thermal obliteration of the bursal lining by irrigation with heated saline. METHODS: First, a pilot animal trial was set up to determine a safe irrigation temperature window. Second, in a human trial the bursae of patients with chronic, recurrent or refractory olecranon bursitis were irrigated with a 3 mL/s flow of physiological saline for a duration of 180 seconds at temperatures between 50 and 52 °C. Patients were followed up for 6 months, allowing for assessment of the surgical site to screen for adverse events, volumetric ultrasound assessment of the bursae, and collection of QuickDASH, Patient Global Impression and Clinical Global impression scores, as well as data on return to activities or work. RESULTS: 24 elbows were prospectively included and underwent a full cycle of hydrothermal ablation. The mean age was 58.4 years (range 40.5 - 81.5), including 20 male and 4 female patients. None had clinical signs of septic bursitis. Bursal fluid cultures were positive in only one case. The average preoperative bursal volume was 11.18 cc (range 4.13-30.75). 18 out of 24 elbows (75%) were successfully treated, showing a complete remission of symptoms or decided improvement within 6 weeks and without any signs of recurrence during the entire follow-up period of 6 months. The average reduction of ultrasound-measured bursal volume was 91.9% in the group of patients that responded to treatment. In patients without recurrence the mean QuickDASH-scores before and after treatment were 13.6 (range 0-50) and 3.1 (range 0-27.5) respectively, showing a statistically significant improvement. All patients were able to fully return to work within 6 weeks after the index procedure. No serious adverse events were encountered. Moderate local adverse events were found in 2 patients. Increasing temperatures of irrigation did not result in a higher treatment efficacy. CONCLUSION: Hydrothermal ablation at temperatures between 50 and 52 degrees is a safe treatment option for recurrent or chronic olecranon bursitis with less complications than open bursectomy and a comparable efficacy.

A novel plating technique for Ideberg type 1 A glenoid fractures: a report of five patients.

BACKGROUND: Glenoid rim fractures are uncommon and generally associated with high complication rates. The most common treatment techniques include screw or anchor fixation. Here, we introduce a new fixation method to treat Ideberg type 1 A fractures. METHODS: A retrospective analysis was performed on patients treated with open reduction and plate fixation for Ideberg type 1 A fractures. The active range of motion capacity of both shoulders was recorded postoperatively. Constant-Murley score and Oxford disability index scores were used as outcome tools. RESULTS: Five patients (three men and two women) were evaluated; their mean age was 56 years (standard deviation (SD), 10 years). The mean follow-up period was 25 months (range, 6-69 months); all fractures healed radiologically during the follow-up period. The mean Constant-Murley score was 80.36 (SD 11.01); the mean Oxford disability index was 37 (SD 9). The subsequent flexion and external rotation of the injured shoulders were similar to those of the uninjured side (injured vs. uninjured side: flexion, 176 ± 5.4 vs. 178 ± 4.4; external rotation, 48 ± 10.9 vs. 60 ± 0). No patient showed signs of osteoarthritis, stiffness, instability, or chronic pain at the last follow-up. DISCUSSION: Open reduction and internal fixation with a plate is suitable for Ideberg type 1A glenoid fractures.

Entrapment of the Median Nerve after Elastic Intramedullary Nailing of a Pediatric Forearm Fracture.

Closed reduction and fixation with elastic intramedullary nails is a popular technique to treat displaced pediatric forearm fractures and has yielded good functional results. Postoperative neurological symptoms can be due to neuropraxia and expectative treatment has been advised for 3 months until further investigation is necessary. We present a case of an 11-year-old boy that presented with median nerve palsy 2 months after a displaced forearm fracture treated with elastic intramedullary nails. Ultrasound and nerve conduction study confirmed the presence of a median nerve entrapped in the callus of the radial fracture. Surgical exploration demonstrated that the nerve was twisted around the intramedullary device. After neurolysis and surgical repair the patient finally recovered 2 years after the operation. This case highlights the possibility of median nerve entrapment after reduction with elastic intramedullary nails. Symptoms should be recognized early, and urgent surgical exploration is needed to prevent irreversible damage.

Coracoid process transfer for anterior shoulder instability : a pectoralis minor sparing method.

The Latarjet procedure alters scapulothoracic motion by releasing the pectoralis minor insertion to the coracoid process and by changing the vector of the conjoint tendon. The purpose of this study is to evaluate the feasibility of retaining the pectoralis minor insertion and a part of the conjoint tendon on to the remainder of the coracoid, and to evaluate the efficiency of the procedure in avoiding scapular dyskinesis, without concessions to glenohumeral stability. Since June 2017, a modification to the Latarjet procedure has been used in the treatment of posttraumatic anterior shoulder instability. The pectoralis minor insertion and a part of the conjoint tendon is retained on its anatomical position, by harvesting only the lateral part of the coracoid. We retrospectively enrolled the first 9 consecutively treated shoulders with a minimum of 6 months follow up and recorded scapulothoracic position and scapulothoracic motion, patient satisfaction, Oxford score, and Short Form (SF)-36. All patients underwent a radiographic review at final follow up. No scapular dyskinesis was observed at final follow- up. Radiographies consistently showed a bony spur at the original osteotomy site, suggesting a functional attachment of the pectoralis minor tendon to the scapula. Harvesting only the lateral part of the coracoid is technically feasible, efficient in treating anterior shoulder instability and avoids scapular dyskinesis. Level of evidence : Level IV, Retrospective Cohort study, Treatment study.

Intra-Articular Osteotomy for Symptomatic Bennett Fracture Malunion.

Bennett's fractures are the most common fractures around the trapeziometacarpal joint but require specialized radiographs to be correctly diagnosed. If a fracture is missed at initial presentation, it may heal with an intra-articular gap, leading to joint incongruency and a painful trapeziometacarpal joint. We present a new technique to correct the intra-articular gap and restore joint congruency in the event of a symptomatic Bennett malunion with a gap of at least 2 mm. The joint is exposed through an anterolateral approach, and the malunion is marked with K-wires under fluoroscopic control. A closing wedge osteotomy with excision of the malunion site is then performed to restore joint congruency. The osteotomy is fixed with 3 interfragmentary screws, and the joint is immobilized for 2 weeks before passive mobilization is initiated. Hardware can be removed between 3 and 6 months postoperatively after consolidation of the osteotomy. We recommend this technique in active patients without trapeziometacarpal osteoarthritis who present with a painful Bennett malunion. Restoration of the joint congruency reduces pain and may prevent the development of posttraumatic osteoarthritis.

Treatment of severe glenoid deficiencies in reverse shoulder arthroplasty: the Glenius Glenoid Reconstruction System experience.

BACKGROUND: The treatment of glenoid bone deficiencies in primary or revision total shoulder arthroplasty is challenging. This retrospective study evaluated the short-term clinical and radiologic results of a new custom-made patient-specific glenoid implant. METHODS: We treated 10 patients with severe glenoid deficiencies with the Glenius Glenoid Reconstruction System (Materialise NV, Leuven, Belgium). Outcome data included a patient-derived Constant-Murley score, a visual analog score (VAS), a satisfaction score, the 11-item version of the Disabilities of the Arm, Shoulder and Hand score, and the Simple Shoulder Test. We compared the postoperative position of the implant with the preoperative planned position on computed tomography scans. RESULTS: At an average follow-up period of 30.5 months, the mean patient-derived Constant-Murley score was 41.3 ± 17.5 points (range, 18-76 points) with a visual analog scale of 3.3 ± 2.5 points (range, 0-7 points). The mean 11-item version of the Disabilities of the Arm, Shoulder and Hand score was 35.8 ± 18.4 (range, 2-71), and the mean Simple Shoulder Test was 47.5% ± 25.3% (range, 8%-92%). Eight patients reported the result as better (n = 3) or much better (n = 5). One patient had an elongation of the brachial plexus, and 1 patient had a period of instability. The average preoperative glenoid defect size was 9 ± 4 cm3 (range, 1-14 cm3). The mean deviation between the preoperative planned and the postoperative version and inclination was 6° ± 4° (range 1°-16°) and 4° ± 4° (range 0°-11°), respectively. CONCLUSION: Early results of the Glenius Glenoid Reconstruction System are encouraging. Adequate pain relief, a reasonable functionality, and good patient satisfaction can be obtained in these difficult cases. Further follow-up will determine the bony ingrowth and subsequent longevity of this patient-specific glenoid component.

Pulley Reconstruction for Symptomatic Instability of the Tendons of the First Extensor Compartment Following de Quervain's Release.

Background Surgical management of de Quervain's tenosynovitis is based on decompression of the first extensor compartment. A simple release of the first compartment can cause instability of the extensor pollicis brevis (EPB) and abductor pollicis longus (APL) tendons in zone seven of the extensors. The WHAT test (wrist hyperflexion and abduction of the thumb) is very effective in diagnosing this instability. Patients and Methods In this retrospective monocentric study, we analyzed a case series of 10 patients all of whom underwent a reconstruction of the first extensor compartment using a retinacular graft because of symptomatic instability after decompression surgery. The reconstruction was a modified technique of the sixth compartment. Functional outcome and characteristics of the newly reconstructed pulley were examined by physical examination with the aid of ultrasound and internationally validated questionnaires. Results Four patients had a good-to-excellent functional outcome, all of those had a maximum of two surgical procedures performed on the first extensor compartment. Six patients presented poor functional outcome. In four of them, more than two surgical procedures were performed. Minor residual instability was noted in six cases, found in both the groups. Conclusion The reconstruction procedures on the first compartment seemed to be satisfactory in treating instability of the EPB and APL tendons after primary surgical release for de Quervain's disease. Level of Evidence Level IV, observational study without controls.

The Oblique Metaphyseal Shortening Osteotomy of the Distal Ulna: Surgical Technique and Results of Ten Patients.

Background Ulnocarpal abutment is a common condition following distal radius fractures. There are different surgical methods of treatment for this pathology: open and arthroscopic wafer procedure or an ulnar shortening osteotomy. We describe an oblique metaphyseal shortening osteotomy of the distal ulna using two cannulated headless compression screws. We report the results of 10 patients treated with this method. Materials and Methods Out of 17 patients, 10 could be reviewed retrospectively for this study. Patient-rated outcomes were measured using the VAS (visual analogue scale) for pain, PRWHE (patient-rated wrist and hand evaluation) survey, and Quick-DASH (disability of arm, shoulder and hand) survey for functional outcomes. At the review we measured the range of motion (ROM) of the wrist (extension and flexion, ulnar and radial deviation, pronation and supination). Grip strength, pronation, and supination strength of the forearm was measured using a calibrated hydraulic dynamometer. ROM and strength of the affected wrist was compared with ROM and strength of the unaffected wrist. Surgical Procedure Oblique long metaphyseal osteotomy of the distal ulna (from proximal-ulnar to distal-radial), fixed with two cannulated headless compression screws. Results The average postoperative VAS score for pain was 23.71 (standard deviation [SD] of 30.41). The average postoperative PRWHE score was 32.55 (SD of 26.28). The average postoperative Quick-DASH score was 28.65 (SD of 27.21). The majority of patients had a comparable ROM and strength between the operated side and the non-operated side. Conclusion This surgical technique has the advantage of reducing the amount of hardware and to decrease the potential hinder caused by it on medium term. Moreover, the incision remains smaller, and the anatomic metaphyseal localization of the osteotomy potentially allows a better and rapid healing.

Parameters influencing glenoid loosening.

INTRODUCTION: There is a lack of organization in existing studies on the outcome and complications of total shoulder arthroplasty. As a result, it is difficult to gain substantial evidence regarding the rate and risk factors for the occurrence of glenoid loosening which remains the most common cause of prosthetic failure. To improve the quality of future studies, an agreement should exist on definitions of glenoid loosening and on the potential risk factors. AREAS COVERED: Reviewing the literature, loosening can be defined as the appearance of radiolucent lines, radiological loosening, clinical loosening and revision as the end stage. Three different categories of influencing parameters can be distinguished: implant related, patient related and surgeon related. Expert commentary: The aim of this review is to organize the available knowledge on glenoid failure, as well as to describe the gaps so that it will constructively contribute to the debate on how to prevent glenoid failure in the anatomic total shoulder arthroplasty.

Fracture of the proximal humerus with disruption of the tendon of the pectoralis major.

Combined pectoralis major disruption and proximal humeral fractures are uncommon. A simple radiologic diagnostic tool which consists of the measurement of the displacement from the humeral shaft to the lateral side of the humeral head (lateral to the outer proximal cortex) can help to diagnose this combined lesion.

Can an extracorporeal glenoid aiming device be used to optimize the position of the glenoid component in total shoulder arthroplasty?

PURPOSE: Successful total shoulder arthroplasty (TSA) requires a correct position of the glenoid component. This study compares the accuracy of the positioning with a new developed glenoid aiming device and virtual three-dimensional computed tomography (3D-CT) scan positioning. MATERIALS AND METHODS: On 39 scapulas from cadavers, a K-wire (KDev) was positioned using the glenoid aiming device. It consists of glenoid components connected to the aiming device, which cover 150° of the inferior glenoid circle, has a fixed version and inclination and is available with several different radii. The aiming device is stabilized at the most medial scapular point. The K-wire is drilled from the center of the glenoid component to this most medial point. All scapulas were also scanned with CT and 3D reconstructed. A virtual K-wire (Kct) was positioned in the center of the glenoid and in the scapular plane. Several parameters were compared. Radius of the chosen glenoid component (rDev) and the virtual radius of the glenoid circle (rCT), spinal scapular length with the device (SSLdev) and virtual (SSLct), version and inclination between KDev and Kct, difference between entry point and exit point ("Matsen"-point). RESULTS: Mean rDev: 14 mm ± 1.7 mm and mean rCT: 13.5 mm ± 1.6 mm. There was no significant difference between SSLdev (110.6 mm ± 7.5 mm) and SSLct (108 mm ± 7.5 mm). The version of KDev and Kct was -2.53° and -2.17° and the inclination 111.29° and 111.66°, respectively. The distance between the "Matsen-point" device and CT was 1.8 mm. CONCLUSION: This glenoid aiming device can position the K-wire on the glenoid with great accuracy and can, therefore, be helpful to position the glenoid component in TSA. The level of evidence: II.

Pulley Reconstruction As Part of the Surgical Treatment for de Quervain Disease: Surgical Technique with Medium-Term Results.

Background Simple decompression of the first extensor compartment is commonly used for treating de Quervain disease, with the possible complication of subluxation of the tendons of the abductor pollicis longus (APL) and extensor pollicis brevis (EPB) over the radial styloid. To prevent this painful subluxation of the tendons, several methods of reconstructing the pulley have been proposed. Questions/Purposes The purpose of our study was to evaluate a new technique for reconstructing the first extensor compartment following a release for de Quervain disease. Patients and Methods A retrospective study (mean length 40.4 months) was performed in 45 patients. The outcome assessment involved two different questionnaires and ultrasound evaluation of any tendon subluxation. Results None of the patients required reoperation for tendon instability or incomplete decompression of the first extensor compartment. Two patients experienced clicking around the radial styloid after surgery. This was not related to the amount of volar migration of the tendons. Conclusions We believe the reconstruction proposed here is an effective method of preventing painful subluxation of the APL and EPB following a release of the first extensor compartment.

De Quervain Tenosynovitis Following Trapeziometacarpal Ball-and-Socket Joint Replacement.

Background One of the surgical treatment options for trapeziometacarpal (TMC) joint arthritis is a prosthetic ball-and-socket replacement. One of the complications in the postoperative setting is de Quervain tendinopathy. Purposes Although this complication has been reported following a resection athroplasty, we questioned whether lengthening of the thumb following the Ivory (Memometal, Stryker Corporate, Kalamazoo, MI, USA) ball-and-socket arthroplasty could be a causal factor. Methods In a prospective study regarding the overall outcome of the Ivory prosthesis, we analyzed 96 cases (83 patients; 69 female, 12 male, 8 bilateral) of primary implanted Ivory prosthesis and the incidence of de Quervain disease during the first year following surgery. We found a particularly high incidence (17%) of de Quervain tendinopathy the first year following this ball-and-socket arthroplasty. We measured the lengthening of the thumb radiographically in the group presenting de Quervain and the asymptomatic group and compared this measure between the two groups. Results We did not find any measurable or statistically significant difference between the groups regarding lengthening. Discussion These findings suggest that lengthening of the thumb following ball-and-socket arthroplasty is not a causal factor in the development of de Quervain tendinopathy within one year after surgery.

Diagnostic value of active protraction and retraction for sternoclavicular joint pain.

BACKGROUND: Sternoclavicular joint (SCJ) arthropathy is an uncommon cause of mechanical pain. The aim of this study is to evaluate the diagnostic value of two active clinical tests for localizing the sternoclavicular joint as the source of mechanical pain. METHODS: All patients between June 2011 and October 2013 that visited the orthopedic departments of three hospitals with atraumatic pain in the area of the SC joint were evaluated. Local swelling, pain at palpation, pain during arm elevation and two newly described tests (pain during active scapular protraction and retraction) were evaluated. CT images were evaluated. The patients were then divided into two groups according to whether they had a ≥50% decrease in pain following the SCJ injection. Sensitivity and specificity for local swelling, the four clinical tests and CT-scan were measured. RESULTS: Forty eight patients were included in this study and SC joint pain was confirmed in 44. The tests with highest sensitivity were pain on palpation, (93% sensitivity) and pain during active scapular protraction (86%). CT-scan showed a sensitivity of 84%. Local swelling showed a high specificity (100%). CONCLUSION: Pain at the SCJ during active scapular protraction is a good clinical diagnostic tool for SC arthropathy.

Use of the clavicular part of the pectoralis major in treatment of failed revision osteosynthesis of the clavicle.

BACKGROUND: Symptomatic atrophic nonunion after multiple clavicle osteosynthesis can be difficult to treat. The aim of this study was to evaluate the results of a transfer of the clavicular part of the pectoralis major muscle as augmentation of osteosynthesis of these nonunions. MATERIALS AND METHODS: A retrospective study included all patients who were treated between 2001 and 2010 (minimum 2-year follow-up). The indications for primary surgery, the number of operations, and the indication for a pectoralis major transfer were evaluated. Time of radiologic consolidation and postoperative complications were assessed. Clinical evaluation was performed with preoperative and postoperative satisfaction ratings and Constant-Murley scores. RESULTS: The study included 11 patients. The indications for a primary osteosynthesis were acute displaced fractures (7), delayed union (2), nonunion (1), and malunion (1). On average, 3.7 procedures were performed (range, 2-6) before the tendon transfer. At revision, there were 2 patients with infection and 9 without infection. Of the 11 clavicles, 10 showed radiologic consolidation after a mean time of 10 weeks (6-20 weeks). The mean follow-up was 62 months (24-132 months). The mean Constant-Murley score increased from 37 (24-55) preoperatively to 59 (43-98), and the satisfaction rating increased from 2 (1-3) to 7 (2-10). Complications included nonunion (1), hardware removal (2), hardware irritation (4), and donor site pain (1). CONCLUSION: The use of the clavicular part of the pectoralis major transfer as an augmentation in revision for symptomatic atrophic nonunion after multiple clavicle osteosynthesis showed good radiologic and acceptable clinical results.

Addition-subtraction osteotomy without ligamentoplasty for symptomatic trapezial dysplasia with metacarpal instability.

Trapeziometacarpal joint pain is often associated with a dynamic adduction deformity of the thumb metacarpal, combined with radial subluxation at the base of the thumb metacarpal, due to trapeziometacarpal dysplasia. Addition-subtraction osteotomy is a surgical option to correct the bony deformity when conservative treatment fails. Eight patients who underwent surgery with this technique were prospectively evaluated. All patients were female and mean age was 42 (range 27-59) years. Mean follow-up period was 23 (range 10-42) months postoperatively. Seven patients (87.5%) were very satisfied. Joint mobility and strength of the operated thumb was restored to a degree comparable to the contralateral thumb. Overall function according to the Quick-DASH score improved by 75.5% and pain according to the Visual Analogue Scale decreased by 65%. Radiological evaluation showed a decrease of the trapezial slope. Mean angle between the articular surface of the trapezium and the long axis of the second metacarpal measured 1420 preoperatively 1290 and postoperatively. In the present study results of addition-subtraction osteotomy without ligamentoplasty were promising, especially for function and pain. The technique may be a valuable treatment option for trapeziometacarpal dysplasia with metacarpal instability.

Epidermoid cyst of the phalanx of the finger caused by nail biting.

Intraosseous epidermoid inclusion cysts of the phalanx of the finger are rare, and are regarded as reactive or post-traumatic pseudotumours. We describe a case of an epidermoid cyst in the distal phalanx of the fifth finger caused by chronic nail biting, which was successfully excised.

Treatment of fractures of the proximal phalanx of long fingers with an isometric traction splint.

Treatment of fractures of the proximal phalanx of the long fingers remains difficult and challenging ; several options have been used. We report our experience with an isometric traction splint, modified from the Southampton design. A cohort of 32 patients with displaced fractures of a proximal phalanx was treated and assessed retrospectively after a short term (9 weeks after splint application). Traction splint was applied to realign the fracture and to control rotation. This construct was used for approximatively 5 weeks (mean: 36 days; range: 21-44 days), considering the usual progression of fracture healing in closed phalangeal fractures and patient tolerance to the splint. Three weeks after splint removal, almost full range of motion was regained in the metacarpophalangeal and interphalangeal joints in all patients, except in 3 cases. Two of these three patients had a displaced fracture of the proximal phalanx as a result of a compression trauma. The combination of the trauma type with static traction splint led to a tenodesis effect with a severe active flexion deficit in the metacarpophalangeal and interphalangeal joints. Our results suggest that isometric traction splint is a valid treatment option for displaced fractures of the proximal phalanx, however compression type fractures should be excluded.

Subscapularis release in shoulder replacement determines structural muscular changes.

BACKGROUND: Osteotomy of the lesser tuberosity in shoulder arthroplasty allows bony healing of the subscapularis tendon but does not prevent fatty degeneration in its muscle. Occurrence or increase in fatty degeneration may depend on the surgical technique. QUESTIONS/PURPOSES: We (1) assessed fatty degeneration in the subscapularis muscle and its cross-sectional area after a C-block osteotomy of the lesser tuberosity with minimal mobilization of the subscapularis muscle, and (2) determined whether this technique had any adverse effect on function, fatty degeneration, and cross-sectional area of the subscapularis muscle. METHODS: We retrospectively examined 36 patients with shoulder replacements who had C-block osteotomies. Constant-Murley scores and clinical signs of subscapularis insufficiency were recorded. We radiographically assessed prosthetic placement. On CT scans, lesser tuberosity healing, fatty degeneration, and cross-sectional area of the subscapularis muscle were determined. The minimum followup was 13 months (mean, 18 months; range, 13-33 months). RESULTS: The mean absolute Constant-Murley score was 71.2. Two patients had weakness of the subscapularis muscle without loss of active motion. All tuberosities healed anatomically. A normal glenohumeral relationship was found in all cases. Fatty degeneration was Grade 0 in 44%, Grade 1 in 39%, Grade 2 in 14%, and Grade 3 in 3%. The subscapularis muscular cross-sectional area decreased from 16.7 cm(2) preoperatively to 14.5 cm(2) postoperatively (13%). CONCLUSIONS: The C-block osteotomy with minimal dissection of the subscapularis is associated with a low incidence of fatty degeneration in the subscapularis muscle after shoulder arthroplasty although the muscular cross-sectional area of the subscapularis decreased. LEVEL OF EVIDENCE: Level IV, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.

Angulated greenstick fractures of the distal forearm in children: closed reduction by pronation or supination.

The purpose of this study was to evaluate a reduction method that is based on the theory of Evans to reduce angulated greenstick fractures of the distal forearm with a rotation manoeuvre, to evaluate an immobilisation technique and to evaluate a brief survey on surgeon practice for treatment of these fractures. A retrospective study was performed on 21 patients. Fractures were reduced with a pronation or supination manoeuvre depending on the angulation of the fracture and were immobilised in pronation or supination. A good reduction was achieved in all patients. Six weeks after manipulation a loss of reduction was seen in 6 out of 21 patients, but with a reangulation of less than 15 degrees. There was no significant difference between fractures immobilized in pronation or in supination. There was no need for remanipulation. At the 2008 Osteosynthesis and Trauma Care Foundation (OTC) meeting, a brief informal survey was performed concerning the reduction method and the use of K-wires after reduction. No surgeons indicated they would perform only a rotation manoeuvre.
