Aims. Resection of the proximal humerus for the primary malignant bone
tumour sometimes requires en bloc resection of the
deltoid. However, there is no information in the literature which
helps a surgeon decide whether to preserve the deltoid or not. The
aim of this study was to determine whether retaining the deltoid
at the time of resection would increase the rate of local recurrence.
We also sought to identify the variables that persuade expert surgeons
to choose a deltoid sparing rather than deltoid resecting procedure. Patients and Methods. We reviewed 45 patients who had undergone resection of a primary
malignant tumour of the proximal humerus. There were 29 in the deltoid
sparing group and 16 in the deltoid resecting group. Imaging studies
were reviewed to assess tumour extension and soft-tissue involvement.
The presence of a fat rim separating the tumour from the deltoid
on MRI was particularly noted. The cumulative probability of local
recurrence was calculated in a competing risk scenario. Results. There was no significant difference (adjusted p = 0.89) in the
cumulative probability of local recurrence between the deltoid sparing
(7%, 95% confidence interval (CI) 1 to 20) and the deltoid resecting
group (26%, 95% CI 8 to 50). Patients were more likely to be selected
for a deltoid sparing procedure if they presented with a small tumour
(p = 0.0064) with less bone involvement (p = 0.032) and a continuous
fat rim on MRI (p = 0.002) and if the
We reviewed 101 patients with injuries of the
terminal branches of the infraclavicular brachial plexus sustained between
1997 and 2009. Four patterns of injury were identified: 1) anterior
glenohumeral dislocation (n = 55), in which the axillary and ulnar
nerves were most commonly injured, but the
Residual muscle weakness in obstetric brachial plexus palsy results in soft-tissue contractures which limit the functional range of movement and lead to progressive glenoid dysplasia and joint instability. We describe the results of surgical treatment in 98 patients (mean age 2.5 years, 0.5 to 9.0) for the correction of active abduction of the shoulder. The patients underwent transfer of the latissimus dorsi and teres major muscles, release of contractures of subscapularis pectoralis major and minor, and
Physiological studies have revealed that the central nervous system controls groups of muscle fibers in a very efficient manner. Within a single skeletal muscle, the central nervous system independently controls individual muscle segments to produce a particular motor outcome. Mechanomyographic studies on the deltoid muscle have revealed that the deltoid muscle, commonly described as having three anatomical segments, is composed of at least seven functional muscle segments, which all have the potential to be at an important level independently coordinated by the central nervous system.[. 1. ] In this study we tried to anatomically describe and quantify these different functional segments within the deltoid muscle, based on the branching out pattern of the
Analysis of orthopaedic malpractice claims has shown that highest impact allegations (highest payment dollars per claim) were those that were related to failure to protect anatomic structures in surgical fields. The prevalence of subclinical peripheral neurologic deficit following reverse and anatomic shoulder arthroplasty has been reported to be 47% and 4%, respectively. We propose the following five rules in order to avoid neurovascular injury during shoulder arthroplasty cases:. Pre-operative planning would assure a smooth operation without intra-operative difficulties. Adequate planning would include appropriate imaging, obtaining previous operative reports, complete pre-operative neurovascular examination and requesting the necessary operative equipment. Tug test: It is crucial to palpate the
In reverse shoulder arthroplasty (RSA), a high complication rate is noted in the international literature (24.7%), and limited local literature is available. The complications in our developing health system, with high HIV, tuberculosis and metabolic syndrome prevalence may be different from that in developed health systems where the literature largely emanates from. The aim of this study is to describe the complications and complication rate following RSA in a South African cohort. An analytical, cross-sectional study was done where all patients’ who received RSA over an 11 year period at a tertiary hospital were evaluated. One-hundred-and-twenty-six primary RSA patients met the inclusion criteria and a detailed retrospective evaluation of their demographics, clinical variables and complication associated with their shoulder arthroplasty were assessed. All fracture, revision and tumour resection arthroplasties were excluded, and a minimum of 6 months follow up was required. A primary RSA complication rate of 19.0% (24/126) was noted, with the most complications occurring after 90 days at 54.2% (13/24). Instability was the predominant delayed complication at 61.5% (8/13) and sepsis being the most common in the early days at 45.5% (5/11). Haematoma formation, hardware failure and
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
Proximal humeral fractures are common fractures that may lead to severe functional disability. In open reduction and internal fixation of these fractures deltopectoral approach is pereferred by many surgeons being an internervous plane and because of familiarity. However when this aprroach is used extensive soft tissue dissection is inevitable and control of the commonly displaced tuberculum majus fragment which is displaced posterolateraly is difficult. In this prospective study we compared deltopectoral and lateral deltoid splitting approach by using the same fixation material. Between October 2005 and March 2007 42 patients were included in the study group. In Group A a lateral deltoid split approch and in Group B deltopectoral approach was used. Group A consisted of 22 cases; mean age 60.95 (26–90 years old); 12 female and 10 male, Group B 20 cases; mean age 56.9 (24–86 years old); 13 female, 7 male. Philos locking plate fixation (Synthes) was used in every case. When deltoid split approach was used
Introduction. Osteoarthritis of the glenohumeral joint leads to global degeneration of the shoulder and often results in humeral or glenoid osteophytes. It is established that the axillary neurovascular bundle is in close proximity to the glenohumeral capsule. Similar to other compressive neuropathies, osteophytic impingement of the
Fractures of the proximal humerus can offer a difficult surgical challenge particularly if they occur in elderly patients and/or are a complex fracture configuration. Much of the morbidity of the surgery relates to the extensile delto-pectoral approach traditionally used for operative treatment of these fractures. A minimally invasive technique for approaching these fractures has was developed using a proximal deltoid split approach at the anterior edge of the deltoid and sliding a precontoured proximal humeral locking plate submuscularly after provisional fracture reduction. This technique was tested in a cadaver model to identify “safe” and “at risk” holes in the plate for percutaneous fixation in relation to the
The patterns of nerve and associated skeletal injury were reviewed in 84 patients referred to the brachial plexus service who had damage predominantly to the infraclavicular brachial plexus and its branches. Patients fell into four categories: 1. Anterior glenohumeral dislocation (46 cases); 2. ‘Occult’ shoulder dislocation or scapular fracture (17 cases); 3. Humeral neck fracture (11 cases); 4. Arm hyperextension (9 cases). The axillary (38/46) and ulnar (36/46) nerves were most commonly injured as a result of glenohumeral dislocation. The
Plate fixation of the proximal humerus fractures may now be more desirable with the use of a biological approach by limiting surgical insult and allowing accelerated rehabilitation by a solid fixation. To evaluate the safety and efficacy of minimally invasive plating of the proximal humerus using validated disease-specific measures. During a period of one year, thirty patients were operated with use of the LCP proximal humerus plate (Synthes) through a 3cm lateral deltoid splitting approach and a second 2 cm incision at the deltoid insertion. The
Purpose: The objective of the study was to perform a prospective evaluation of thermal capsulorraphy for the treatment of multidirectional instability of the shoulder. Summary of Methods: Over a period of two years, 19 patients with multidirectional instability were treated with thermal shrinkage. Fifteen patients had involuntary dislocation and four voluntary. The predominant direction of instability was anterior/inferior in 10, posterior in 5 and multiple directions in 4. Patients were followed for a minimum of two years or until surgical failure and recurrence of symptomatology. Postoperatively patients were immobilised in a sling for a period of 3 weeks and were reviewed at 6 weeks and 3, 6, 9 and 12 months and then at six monthly intervals. The Western Ontario shoulder Instability Index was used as a clinical outcome measure as well as subjective and objective evaluation of patient’s function, range of motion, pain and instability. Results: Nine patients had recurrence of their instability occurring at an average of nine months following their surgical procedure (range 7–14 months). One patient had
Introduction and purpose: Different neurovascular structures may be damaged when making arthroscopic portals to the shoulder joint. The description of new portals poses new challenges. The goal of the present study is to provide an update on the anatomic vasculonervous responses of the current approaches to shoulder arthroscopy. Materials and methods: 16 fresh cadavers were systematically dissected. The most usual arthroscopic portals were marked and, then, the dissection started on a plane-to-plane basis. Relationships were identified and distances were measured to the most important neurovascular elements with a standard caliber (accuracy: 0.5mm). Results: The portals studied and the structures at risk were the following:. * Posterior portal: anterior branch of the
Abstract. Background/Objectives. The incidence of reverse total shoulder replacement (rTSR) implantation is increasing globally, but apprehension exists regarding complications and associated challenges. We retrospectively analysed the senior author's series of rTSR from a tertiary centre using the VAIOS shoulder system, a modular 4th generation implant. We hypothesised that the revision rTSR cohort would have less favourable outcomes and more complications. Methods. 114 patients underwent rTSR with the VAIOS system, over 7 years. The primary outcome was implant survival. Secondary outcomes were Oxford shoulder scores (OSS), radiographic analysis (scapular notching, tuberosity osteolysis, and periprosthetic radiolucent lines) and complications. Results. There were 55 Primary rTSR, 31 Revision rTSR and 28 Trauma rTSR. Implant survival: Primary rTSR- 0 revisions, average 3.35-year follow-up. Revision rTSR-1 revision (4.17%), average 3.52-year follow-up. Trauma rTSR- 1 revision (3.57%), average 4.56-year follow-up OSS: Average OSS improved from 15.39 to 33.8 (Primary rTSR) and from 15.11 to 29.1 (Revision rTSR). Average post-operative OSS for the Trauma rTSR was 31.4 Radiological analysis and complications: Low incidence of scapular notching One hairline fracture below the tip of stem, noted incidentally, which required no treatment. One periprosthetic fracture after alcohol related fall. Treated non-surgically One joint infection requiring two-stage revision to rTSR. One dislocation noted at 2 year follow up. This patient had undergone nerve grafting within 6 months of rTSR for
The standard approach is through the deltopectoral interval. Among patients with prior incisions, one makes every effort to either utilise the old incision or to incorporate it into a longer incision that will allow one to approach the deltopectoral interval and retract the deltoid laterally. The deltopectoral interval is most easily developed just distal to the clavicle, where there is a natural infraclavicular triangle of fat that separates the deltoid and pectoralis major muscles even in very scarred or stiff shoulders. Typically, the deltoid is retracted laterally leaving the cephalic vein on the medial aspect of the exposure. The anterior border of the deltoid is mobilised from the clavicle to its insertion on the humerus. The anterior portion of the deltoid insertion together with the more distal periosteum of the humerus may be elevated slightly. The next step is to identify the plane between the conjoined tendon group and the subscapularis muscle. Dissection in this area must be done very carefully due to the close proximity of the neurovascular group, the
Abstract. Introduction. Local anaesthetic injections are regularly used for perioperative pain relief for shoulder arthroscopies. In our practice all shoulder arthroscopies were performed under general aneasthesia supplemented by perioperative subacromial local anaesthetic injections or landmark guided

After establishing anatomical feasibility, functional reconstruction to replace the anterolateral part of the deltoid was performed in 20 consecutive patients with irreversible deltoid paralysis using the sternoclavicular portion of the pectoralis major muscle. The indication for reconstruction was deltoid deficiency combined with massive rotator cuff tear in 11 patients, brachial plexus palsy in seven, and an isolated
Latissimus dorsi tendon transfer (LDTT) is technically
challenging. In order to clarify the local structural anatomy, we undertook
a morphometric study using six complete cadavers (12 shoulders).
Measurements were made from the tendon to the nearby neurovascular
structures with the arm in two positions: flexed and internally
rotated, and adducted in neutral rotation. The tendon was then transferred
and measurements were taken from the edge of the tendon to a reference
point on the humeral head in order to assess the effect of a novel
two-stage release on the excursion of the tendon. With the shoulder flexed and internally rotated, the mean distances

Although new locking plates allows for secure fixation of osteoporotic fractures in the proximal humerus, extensive soft tissue dissection is needed for their insertion. We report on a prospective clinical trial of the first thirty patients treated with plating of the proximal humerus though a minimally invasive percutaneous approach. All fractures healed within the first 6 months with no avascular necrosis or

due to nonunion of a fracture of the proximal third of the humerus may
benefit from reverse total shoulder replacement. This paper reports
a prospective, multicentre study, involving three hospitals and
three surgeons, of 35 patients (28 women, seven men) with a mean
age of 69 years (46 to 83) who underwent a reverse total shoulder
replacement for the treatment of nonunion of a fracture of the proximal humerus.
Using Checchia’s classification, nine nonunions were type I, eight
as type II, 12 as type III and six as type IV. The mean follow-up
was 51 months (24 to 99). Post-operatively, the patients had a significant
decrease in pain (p <
0.001), and a significant improvement in
flexion, abduction, external rotation and Constant score (p <
0.001), but not in internal rotation. A total of nine complications
were recorded in seven patients: six dislocations, one glenoid loosening
in a patient who had previously suffered dislocation, one transitory

Proximal humerus is the common site for primary bone malignancies that surgical treatment consists of wide excision of the tumor and reconstruction with tumor resection prosthesis or allograft. The ultimate function of the shoulder depends on the degree of sacrification of adjacent structures. Thirty-two patients with primary malignancies have been treated by wide excision and endoprosthetic replacement by senior author between 1989–2005 12 patients were female, 20 patients were male, mean age was 26,6 years (range 7–69 years). Histological diagnosis was 14 osteosarcoma, 4 Ewing’s sarcoma, 4 chondrosarcoma, 3 parosteal sarcoma, 4 giant cell tumor, 1 aneurysmal bone cyst, 2 synovial sarcoma. Synovial sarcoma, osteosarcoma and Ewing’s sarcoma patients received neoadjuvant chemotherapy prior to excision. Mean follow-up was 50,4 months (range 6–153 months). Oncologic results were 20 patients NED (no evidence of disease), 2 patients AWD (alive with disease), 10 patients DOD (died of disease). Functional outcome was scored according to Musculo-Skeletal System Tumor Society (MSTS) rating scale, 7 patients were excellent, 22 patients were good and 3 patients were poor. Regarding complications 2 patients developed local recurrence, 2 patients had superficial infection. Infected cases were treated by systemic antibiotic treatment. All patients had dexterity of the hand and elbow. Regarding shoulder abduction and forward flexion, 7 patients whose deltoid muscle and
Background: The Inferior Glenohumeral Ligament (IGHL) has a well known mechanical and propioceptive relevance in shoulder stability. The interrelation of the IGHL anatomical disposition and innervation has not actually been described. The studys purpose was to determine the IGHL innervation patterns and relate them to dislocation. Material &
methods: Forty-five embalmed and 16 fresh-frozen human cadaveric shoulders were studied. Massons Trichrome staining was used to detail the intra-ligamentous nerve fibre arrangements. Neural behaviour of the articular nerves was studied dynamically at the apprehension position and while anteroinferior dislocation of the shoulder joint was performed. Results: The anatomy of the IGHL was clearly defined. However, in 7 out of 61 cases the anterior band was only a slight thickening of the ligament. It averaged 34 mm (range, 28 to 46 mm) in length. The posterior band was only seen in 40.98 % of the cases. The
Treatment of proximal humerus fractures (PHF) is controversial in many respects, including the choice of surgical approach for fixation when using a locking plate. The classic deltopectoral (DP) approach is believed to increase the risk of avascular necrosis while making access to the greater tuberosity more difficult. The deltoid split (DS) approach was developed to respect minimally invasive surgery principles. The purpose of the present study (NCT-00612391) was to compare outcomes of PHF treated by DP and DS approaches in terms of function (Q-DASH, Constant score), quality of life (SF12), and complications in a prospective randomized multicenter study. From 2007 to 2016, all patients meeting the inclusion/exclusion criteria in two University Trauma Centers were invited to participate in the study. Inclusion criteria were: PHF Neer II/III, isolated injury, skeletal maturity, speaking French or English, available for follow-up (FU), and ability to fill questionnaires. Exclusion criteria: Pre-existing pathology to the limb, patient-refusing or too ill to undergo surgery, patient needing another type of treatment (nail, arthroplasty),
Latissimus dorsi anterior to major transfers have been advocated in the setting of loss of external rotation and elevation in conjunction with reverse shoulder replacement. Reverse shoulder replacement is a prosthesis specifically designed for shoulders with poor rotator cuff function. In the vast majority of cases, some teres minor function at the minimum is maintained in shoulders destined for a reverse shoulder replacement. However, in certain circumstances there is complete loss of any external rotation, and a muscle transfer can be performed in order to restore some external rotation function. A reverse shoulder replacement in the absence of any rotator cuff function goes into obligate internal rotation with elevation. A minimum of external rotation strength is necessary in order to maintain the arm in normal rotation. The first tip is patient selection. Physical examination of active external rotation, external rotation strength and forward elevation should be just performed. A latissimus transfer is indicated in patients who cannot maintain their arm in neutral to at least a few degrees of external rotation. A lag sign is another physical examination finding which can indicate complete loss of rotator cuff function. The latissimus dorsi transfer is performed by first identifying and releasing the latissimus from its insertion on the anterior humerus. The arthroplasty is performed. The passage for the latissimus muscle is developed carefully and being mindful of the
Reverse shoulder arthroplasty is becoming a frequent treatment of choice for patients with shoulder disorders. Complication rates after reverse shoulder arthroplasty may be three-fold that of conventional total shoulder arthroplasty especially in high risk patient populations and diagnoses like revision arthroplasty, fracture sequelae, and severe glenoid bone loss. Complications include component malposition, stiffness, neurological injury, infection, dislocation or instability, acromial or scapular spine fractures, scapular notching, and loosening of implants. Recognition of preoperative risk factors and appropriate 3D planning are essential in optimizing patient outcome and intraoperative success. Failure of reverse shoulder arthroplasty is a significant challenge requiring appropriate diagnosis of the failure mode. The most common neurological injuries involve the brachial plexus and the
Shoulder arthritis in the young adult is a deceptive title. The literature is filled with articles that separate outcomes based on an arbitrary age threshold and attempt to provide recommendations for management and even potential criteria for implanting one strategy over another using age as the primary determinant. However, under the age of 50, as few as one out of five patients will have arthritis that can be accurately classified as osteoarthritis. Other conditions such as post-traumatic arthritis, post-surgical arthritis including capsulorrhaphy arthropathy, and rheumatoid arthritis create a mosaic of pathologic bone and soft tissue changes in our younger patients that distort the conclusions regarding “shoulder arthritis” in the young adult. In addition, we are now seeing more patients with unique conditions that are still poorly understood, including arthritis of the pharmacologically performance-enhanced shoulder. Early arthritis in the young adult is often recognised at the time of arthroscopic surgery performed for other preoperative indications. Palliative treatment is the first option, which equals “debridement.” If the procedure fails to resolve the symptoms, and the symptoms can be localised to an intra-articular source, then additional treatment options may include a variety of cartilage restoration procedures that have been developed primarily for the knee and then subsequently used in the shoulder, including microfracture, and osteochondral grafting. The results of these treatments have been rarely reported with only case series and expert opinion to support their use. When arthritis is moderate or severe in young adults, non-arthroplasty interventions have included arthroscopic capsular release, debridement, acromioplasty, distal clavicle resection, microfracture, osteophyte debridement,
Optimal surgical management of proximal humeral fractures remains controversial. We report our experience and the study on our surgical technique for proximal humeral fractures and fracture-dislocations using locking plates in conjunction with calcium sulphate augmentation and tuberosity repair using high strength sutures. We used the extended deltoid-splitting approach for fracture patterns involving displacement of both lesser and greater tuberosities and for fracture-dislocations. We retrospectively analysed 22 proximal humeral fractures in 21 patients. 10 were male and 11 female with an average age of 64.6 years (Range 37 to 77). Average follow-up was 24 months. Fractures were classified according to Neer and Hertel systems. Pre-operative radiographs and CT scans in three and four-part fractures were done to assess the displacement and medial calcar length for predicting the humeral head vascularity. According to the Neer classification, there were 5 two-part, 6 three-part, 5 four-part fractures and 6 fracture-dislocations (2 anterior and 4 posterior). Results were assessed clinically with DASH scores, modified Constant & Murley scores and serial post-operative radiographs. The mean DASH score was 16.18 and modified Constant & Murley score was 64.04 at the last follow-up. 18 out of 22 cases achieved good clinical outcome. All the fractures united with no evidence of infection, failure of fixation, malunion, tuberosity failure, avascular necrosis or adverse reaction to calcium sulphate bone substitute. There was no evidence of
Non-operative management has frequently been adopted for closed injuries of the infraclavicular brachial plexus and its branches in the belief that spontaneous recovery is likely to occur, and surgical exploration is performed only if recovery has not occurred in the expected time. This paper correlates the clinical and electrophysiological features with the operative findings in six patients with such injuries. The
The scapula is a rare site for a primary bone tumour. Only a small number of series have studied patient outcomes after treatment. Previous studies have shown a high rate of recurrence, with functional outcomes determined by the preservation of the glenohumeral joint and deltoid. The purpose of the current study was to report the outcome of patients who had undergone tumour resection that included the scapula. We reviewed 61 patients (37 male, 24 female; mean age 42 years (SD 19)) who had undergone resection of the scapula. The most common resection was type 2 (n = 34) according to the Tikhoff-Linberg classification, or type S1A (n = 35) on the Enneking classification.Aims
Methods
Opinion varies as to the incidence of nerve lesions in anterior dislocation of the shoulder after low-velocity trauma. Most studies are retrospective or do not use EMG. We have investigated the incidence and the clinical consequences of nerve lesions in a prospective study by clinical and electrophysiological examination. Axonal loss was seen in 48% of 77 patients. The
We describe 11 cases of posterior fracture-dislocation of the shoulder that required open reduction and fixation. Difficulties with access through anterior approaches led us to use the superior subacromial approach. This is an extension of the approach often used to expose the rotator cuff; the joint is opened by splitting the supraspinatus tendon 5 mm behind the cuff interval. The glenoid, proximal humerus and any fracture fragments can be seen from above, allowing reduction of the dislocation and osteosynthesis to be performed with minimal risk of damage to the humeral head and its blood supply. The proximity of the
We reviewed 28 patients with brachial plexus lesions caused by shoulder dislocation. Contrary to most other reports, we found that the neurological lesions involved the infraclavicular and the supraclavicular brachial plexus. With supraclavicular lesions the involvement was always of the suprascapular nerve, and this always recovered spontaneously. Isolated
Displaced proximal Humeral fractures at Inverclyde Royal Hospital prior to 2008 were previously treated with the antegrade Acumed Polaris Proximal Humeral, predominantly in 2 part fractures. The Philos plate was introduced in 2008, initially being used to treat select non unions, and then expanded to acute fractures. The aim of this study was to assess time to union and complications in the lower volume District General setting comparing to published outcomes. From February 2008 – January 2011, 20 patients were identified. Age range 49–75 (mean 61.2) years, 8 male; 12 female. Left 9, Right 11 Neers 2 part 35%; 3 35%; 4 30%. 16 (80%) were performed in acute fractures with 4 for non-unions, 3 of which were previous polaris nail fixations. 2 patients were lost to follow up after 6/52 but were progressing well. Union was confirmed radiologically and clinically in all but 2 remaining patients (10%), one of whom suffered a significant complication of plate fracture, the second treated with revision for painful non union. 2 other significant complications were observed: transient
Traumatic rupture of the tendon of the subscapularis muscle was documented as an isolated lesion in the shoulders of 16 men. The injury was caused either by forceful hyperextension or external rotation of the adducted arm. The patients complained of anterior shoulder pain and weakness of the arm when it was used above and below the shoulder level. They did not experience shoulder instability. The injured shoulders exhibited increased external rotation and decreased strength of internal rotation. A simple clinical manoeuvre called the 'lift-off test', reliably diagnosed or excluded clinically relevant rupture of the subscapularis tendon. Confirmation of the clinical diagnosis was best achieved by ultrasonography or MRI, but arthrography or CT arthrography were also useful. Surgical exploration confirmed the diagnosis in every case. Repair of the ruptured tendon was technically demanding and required good exposure to identify and protect the
In 45 patients we assessed the functional results and complications for three different reconstructive procedures after resection of primary tumors of the proximal humerus. An osteoarticular allograft was used in 11, a clavicula pro humero operation in 15 and a tumour prosthesis in 19. The glenoid was resected with the proximal humerus in 25 patients. The
Our purpose was to study the functional outcome and electrophysiologically to assess the axially nerve function in patients who have undergone surgery using a deltoid-splitting approach to treat complex proximal humeral fractures. This was a prospective observational study and was carried out in the Shoulder injury clinic at a university teaching hospital. Over a one-year period we treated fourteen locally-resident patients (median age 59 years) who presented with a three- or four-part proximal humeral fracture. All patients were treated using the extended deltoid-splitting approach, with open reduction, bone grafting and plate osteosynthesis. All patients were prospectively reviewed and underwent functional testing using the DASH, Constant and SF-36 scores as well as spring balance testing of deltoid power, and dynamic muscle function testing. At one year after surgery, all patients underwent EMG and nerve latency studies to assess
We conducted a prospective evaluation of patients with anterior dislocation of the shoulder associated with a fracture of the greater tuberosity. Thirty-four anterior dislocations of the shoulder with greater tuberosity fractures were reviewed with a minimum follow-up of one year from the time of injury. Eight required open reduction. The final outcome with regard to pain, range of movements, and function was assessed in 34 patients. In open reduction, there were five good results, one fair, one poor and one patient died. In the non-operative group, results were good in 11 patients, fair in eight, poor in one, not assessed in five and one patient died. Two patients have died in this series, one in the open reduction group. Associated injuries are:
Complications in internal fixation of proximal humeral fractures can lead to an unsatisfactory outcome. We retrospectively reviewed 22 patients at a mean follow-up of 13 months (range 3–30). The average age was 58 years (36–86) in 10 male and 12 female patients. The mechanism of injury involved a simple fall in 17, MCA in 3, assault in 1 and metastasis in 1. The operation was performed at a mean of 11 days after the injury (range 1–29). There were 12 3-part, 6 2-part, 2 4-part fractures, 1 fracture dislocation and 1 pathological fracture. Only 13 out of 22 patients (59%) did not develop any complications. We had hardware problems in 5 patients including hardware pull-out, plate prominence, screw penetration, loosening or breakage. 2 wound infections, 1
Although, reverse shoulder arthroplasty has initially been introduced for rotator cuff arthropathy, its application has been expanded on fracture sequelae, chronic dislocations and even comminuted fractures of the humeral head in elderly patients. The purpose of this study is to present our experience and the mid-term clinical results of this type prosthesis. Between 2006 and 2008 16 reverse shoulder arthroplasties have been carried out in our department. Fourteen patients were female and 2 male with an average age of 72.4 years (55–81). Eleven patients had true rotator cuff arthropathy, 3 malunion of 4-part fractures, one chronic anterior shoulder dislocation and finally one patient had bilateral chronic posterior shoulder dislocation. In 2 cases we used the Delta prosthesis and in a further 14 cases the Aquealis Arthroplasty. Routine postoperative follow up was at 3,6,12 and 24 months and included plain radiographic control and clinical evaluation with the Constant Shoulder Score. All patients report significant pain relief and an average improvement of the Constant Score from 40.5 to 72.3. Two patients had anterior dislocation of the prosthesis 4 days postoperatively and we proceeded to the application of a 9 mm metal spacer and bigger polyethylene size. In one patient neuroapraxia of the
